The Complete Air Purifier Buying Guide

You may have heard about the latest boom of using air purifiers.

There has been a surge in the sales and use of air cleaning appliances in the latest years, which is due to the growing concern over the quality the air which we breathe both outside and indoors.

It is also caused by the rising numbers of people suffering from different allergies, asthma and other respiratory and skin problems due to the pollution in the air.

Just recently, the US Environmental Protection Agency declared that the quality of the air inside our homes could be about five times and even more polluted than that outdoors. The main reasons are the constructions of the housing, as well as the harmful contaminants we bring home, or those released by our pets, household items, smoke, and others.

Since most people spend about 90% of their lives inside their homes, it is understandable that there has been a growing interest in improving the healthy environment inside, including air quality.

Thanks to modern air purifiers, you can rest assured that your home is free of allergens, toxins, pollutants, germs, bacteria, and other harmful microorganisms or particles.

But due to their increasing popularity, it has become quite a challenge for people to choose the most suitable air purifier for their needs.

The truth is, all air purifiers have a single goal of cleaning the air, but the different devices do it in different ways, and while some are designed to clean allergens, others are made for eliminating germs and viruses, while there are purifiers which deal with the bad smells and smoke inside.

We realize how confusing choosing the most appropriate air purifier can be which is why we have created this complete air purifier buying guide for you.

Read on to find out about the different types of air purifying devices, the types of pollutants they can eliminate the advantages of each type, and the features to look for when shopping for the best air purifier for your home or office.

What is an Air Purifier?

As its name suggests, the air purifier is a device which will filter and clean the air in your room, home or any other indoor area.

The different air purifiers use different filters and air filtering methods to clean the air and remove the airborne pollutants and other harmful particles.

The goal is to reduce the number of these potentially harmful pollutants from the air that you breathe and the air you are exposed to, in order to lower the risks of allergic reactions, lung and other respiratory problems, skin irritations, headaches, problems sleeping and other health issues which can arise when you are exposed to bad quality or potentially harmful air.

Breathing clean and fresh air is especially important for allergy or asthma sufferers who know how uncomfortable and even life-threatening breathing airborne irritants or allergens can be.

But even if you don’t have any health problems, you will still benefit from breathing clean air. This will alleviate the stress on your lungs, as well as improve your sleep, your mood, your cognitive function, and your productivity.

Also, your home will become cleaner, and the need for regular vacuuming and dusting will decrease.

Overall, you will find that your health and wellbeing will drastically improve if you start using an air purifier suitable for your home and for your specific needs.

What Airborne Pollutants do Air Purifiers Remove?

These powerful air filtering machines can remove a wide variety of visible and invisible pollutants from the air in your home.

Here are some of the common pollutants which can be captured, trapped or eliminated by most air purifiers:

  • Pollen from trees, grass or flowers
  • Fungi and plant spores
  • Dust
  • Dust mites
  • Pet hair and pet dander
  • Mold spores
  • Bacteria, germs, and viruses
  • Tobacco smoke and smell
  • Wood smoke and smell
  • Odors from cooking, cleaners, pets, and others
  • Toxins and fumes from chemicals, pesticides, and aerosol sprays
  • VOCs (Volatile Organic Compounds) from paints, cleaning detergents, varnishes, construction materials, new furniture or carpets, and others

Each of these air pollutants can be dangerous for the health, no matter whether you suffer from asthma, an allergy or are completely healthy.

The difference of the effect of these pollutants on people with such sensitivities is that the effect can show up immediately, while with healthy people, the effect may show up later on as a result of long-term exposure to one or more of these harmful airborne particles.

What exactly do you need an Air Purifier for?

When you are shopping for the best air purifier, it is essential to define why exactly you want it.

The reason for this is that most air purifiers are not made to tackle each and every pollutant found in the air.

In fact, most of them are designed and made to tackle specific airborne pollutants.

This is why it is vital to determine exactly what type of problem you are trying to tackle in order to find the best and most efficient air purifier for your needs.

Here are some of the basic questions you want to ask yourself before proceeding to invest in an air purifier, in order to make sure that you are making the best choice possible:

  • Do you have seasonal allergies, such as hay fever?
  • Do you have pet allergies and own a pet?
  • Are you planning on renovating your home and need to remove the harmful fumes and dust?
  • Do you or other members of your family often fall sick from viruses and infections?
  • Do you need a device to sterilize your home from all viruses, germs, and bacteria?
  • Do you have pets and want to deal with the problems with shedding, dander or odor?
  • Do you or someone at home smoke, and you want to get rid of the smoke and the smell?

After you have answered these, questions, it will be much easier to find the most suitable type of air purifier which will perform the air cleaning task you have purchased it for.

Read on to find out more about these different types of air-purifying devices, and the pros and cons of each one, and to find out more about the features to look for when shopping for an air purifier.

The most common reasons why people are buying air purifiers

Apart from the fact that the different air purifiers utilize different filtering and air cleaning systems and technologies, they also have different features which can be especially convenient for some people.

Here are the most common reasons why people are buying air purifiers in 2019:

To alleviate allergies

It is a shocking fact that more than 50 million people in the US suffer from respiratory or nasal allergies, which are commonly caused by airborne irritants.

Some air purifiers with pre-filters and True HEPA filters are incredibly efficient for removing the airborne and other allergens from home. Some of these common allergens are: pollen, pet hair, and dander, dust and dust mites, mold spores, smoke, and others.

Allergies to these irritants can cause serious discomfort and unpleasant symptoms such as eye inching and watering, nasal congestion, sneezing, coughing, wheezing, skin irritations, hives, headaches, and others.

By preventing exposure to the allergens, the need for medicaments and for treatment of the symptoms will decrease drastically which is why many people are buying and using air purifiers in their homes.

To help alleviate asthma

Unfortunately, over 300 million around the world suffer from asthma. Even worse, there is no known cure for asthma, and asthmatics often need to take medication and use inhalers on a daily basis to manage the symptoms and prevent dangerous asthma attacks.

One of the main causes of asthma issues and attacks is breathing air which is polluted.

Fortunately, an air purifier with a True HEPA filter can help remove these irritants from the air and can make life easier for people with asthma.

To reduce the dust buildup indoors

Dust can build up in your home no matter how often and how much you clean. In fact, cleaning can cause even more dust to become airborne.

Dust comes from the dirt we bring indoors, from our pets, from the dead skin cells from our bodies, from parts of foods, from insect dropping and from other pollutants which occur in any household.

Dust attracts dust mites which causes problems for those allergic to them.

A good air purifier capable of sucking in and trapping the airborne dust and dust mites can help alleviate the dust allergies, as well as reduce the buildup of dust indoors.

This is great news if you want to clean less but still live in a nice and clean home.

For mold elimination

Everybody knows that mold and mold spores can be harmful to the health, especially after prolonged exposure to them.

Some people already have chronic diseases due to being exposed to too much mold, and others suffer from allergies or other adverse effects from the mold spores which float in the air that we breathe.

There are some specialized air purifiers which are designed to filter out and eliminate mold spores from the air, and thus help eliminate the mold from the home.

There are also air purifiers which can eliminate the nasty mold odor from your home for good as well.

For reduction of pet hair and pet dander

About 30% of US adults and 40% of the children suffer from nasal allergies due to pet allergens. The main allergen is pet dander which is very difficult to remove from the environment indoors if you have a dog, cat or other pet.

Some pet owners who do not suffer from allergies are looking for ways to deal with the problem of fur and hair shedding in their homes as well.

There are excellent quality air purifiers which are capable of fixing both the issue with pet dander and with pet hair.

They work by collecting and trapping the hair and the danger which the pets shed.

This can not only help alleviate the symptoms of pet allergies but will also make your home much cleaner and free of pet hair stuck on every piece of furniture, carpet or just about anywhere else, which is a common sight in homes with pets, especially during the shedding seasons.

For removing smoke and its smell

Unfortunately, even after solid evidence about the risks of smoking, many people continue to smoke cigarettes, cigars or pipes indoors.

This can be very unpleasant and risky for both the smokers and the non-smokers in the household.

Second-hand tobacco smoke is known to cause a wide variety of health issues, including stroke, heart attacks, asthma attacks, respiratory and ear problems, problems with the development of unborn babies, reproductive problems and various types of cancer.

The good news is, there are air purifiers which are capable of efficiently collecting and trapping both the smoke and the smell of the smoke as well.

This is no doubt a huge relief for the non-smokers at home, especially if you have babies, small children, people with respiratory problems or people with weakened immune systems or pets at home.

Such air cleaning systems are also very useful for eliminating the smoke and smell from wood fires and wildfires.

So, now that you have hopefully managed to narrow down the reasons why you are interested in buying an air purifier, let’s take a look at the different types of air purifiers available on the market as well as the features to look for and those to avoid when shopping for one.

The different types of Air Purifiers to choose from

Since you are reading this article, chances are you have already done some research on air purifiers, so you have probably noticed just how many different types, models, brands and sizes are available on the market.

Even though the choice may look endless, the good news is that there are actually only four main types of air purifiers, or more specifically – there are four main types of filtration systems which these ingenious air cleaning devices use.

These are the four filtration types used in air purifiers:

HEPA (High Efficiency Particulate Air) Filters

HEPA filters are highly efficient filters which trap allergens, pollen, mold spores, dust, fungi, pet dander, pet hair, smoke, and other airborne particles. Even better, once trapped, these pollutants remain in the filter and are not released back in the air.

They are made either of highly dense paper, or mesh, and are a superb option for people suffering from allergies and asthma, as well as for those who want a cleaner and dust and hair-free home.

The mesh HEPA filters can be washed and reused, but the paper ones need to be replaced once in every 6-8 months.

Keep in mind, that if you want the best HEPA filtering system, you should look for air purifiers labeled as True HEPA devices.

This label is issued only for rated and certified filters which are capable of removing 99.97% airborne particles sized as small as 0.3 microns.

Other cheaper devices labeled as HEPA like or HEPA type will also clean the air but will capture the larger airborne particles and may not be able to filter out the smaller allergens and pollutants.

Unfortunately, a HEPA filter alone cannot remove odors or fumes from chemicals.

Ionic Filtration

This air filtering technology utilizes charged ions which are sent into the air by the ionic generator, and then attach themselves to the airborne contaminants.

As a result, they become too heavy to keep floating in the air and fall down to a dedicated tray or to the floor or other surfaces, where they need to be cleaned up with a vacuum cleaner.

Ionizers can remove airborne particles sized as small as 0.01 microns, including dust, mold spores, pollen, VOCs, fungi, bacteria, viruses, and smoke.

Ionizers are less expensive than HEPA filters and do not require filter replacements. They are also quieter than other air purifiers because they don’t have fans.

But keep in mind that these devices with ionic filtration will keep the pollutants out of the air, but they will still remain in the room (on the floor or furniture) until cleaned up.

Also, the negatively charged ions and the ozone created by the process are known to worsen the symptoms of asthma, so this type of filter is definitely not recommended for people with asthma or other chronic respiratory problems.

Carbon Filtration

These filters are made of porous carbon and are highly efficient in capturing and eliminating odors, gases, and fumes.

They are perfect for homes with smokers, as well as for those who want to get rid of the odor from cooking, their pets, the trash or others.

On the other hand, the carbon filter alone will not purify the air from other harmful particles, which is why it should be combined with another filter if you want to breathe both odor-free and clean air.

Ultra Violet (UV) Light

The air purifiers which utilize UV light actually emit this invisible light which attacks the pollutants in the air. The light is contained inside the device, and it is completely safe for people.

The purpose of the light is to kill the viruses and bacteria by destroying their DNA structures.

The UV light is a super option if you want to sanitize your home and kill off all germs, bacteria, and viruses.

It does not though purify the air from the other airborne particles.

So, if you want the effect of the UV light but also want your air filtered from pollutants, you should opt for an air purifier which has both a HEPA filter and a UV light function.

Other air purifier variations

Air purifiers can also be divided into two other types – smart and classic.

The classic air purifiers will clean the air in your home, but will not give you feedback regarding the air quality. Some of these purifiers do have air quality sensors and digital controls which help them work more efficiently, but still, you will know how the device is working only by looking at the filter and how dirty it is.

The smart air purifiers connect via apps to smartphones and other mobile devices and will inform you about the type and quantity of the pollutants in your air in real time.

These smart devices will keep you updated about the air quality in your home, and how efficiently it is being filtered.

What do ACH and CADR mean?

When you’re looking to buy an air purifier you’ll sometimes come across these two ratings in the specifications list.

Here is what these abbreviations stand for and what kinds of numbers to look for when you are shopping for an air cleaning device for your home or office:

ACH

ACH is an abbreviation for Air Changes per Hour.  It is one of the most important features to consider when you are choosing an air purifier for your needs.

It means the number of times the air purifier is able to completely clean and filter the air in a room of a specific size.

Look at the size and area for which the device is rated first. This is the first thing to keep in mind when choosing the best air cleaning appliance for your specific room, home or another area.

You should pick a purifier which is capable of filtering the air in that specific area or larger. Never opt for one which does not have the maximum capacity to cover the area you need it for, because then it will not clean the air efficiently, and thus will not serve its main purpose.

Now that you have determined that you need an air purifier rated for a room which is let’s say 400 square feet, you should look at its ACH number. If it says ACH 4x this means that the device will completely filter the air in a room sized 400 square feet or less 4 times per hour.

So, the higher the ACH number is – the better the machine will be able to keep the air clean in this room or area.

CADR

CADR is an abbreviation for Clean Air Delivery Rate. This is a specific rating which was developed by the AHAM (Association of Home Appliance Manufacturers) which helps consumers know how efficient the device is for cleaning the air from specific pollutants in a roo0m of a specific size or smaller.

Not all air purifiers have a CADR rating in their specifications. Only the ones which have been tested and rated by the AHAM will include this number.

The higher the CADR rating – the more efficient the air purifier is for filtering some types of common pollutants including pollen, dust and tobacco smoke.

Once again, the CADR rating is tightly connected to the maximum square footage for which the appliance is rated too.

So, when shopping for an air purifier, always first look for the maximum room size capacity which the device is made for, and then when you find one which is capable of cleaning up an area you are interested in, look for the CADR rating it has.

The tests done by AHAM are for the three most common airborne pollutants: dust, tobacco smoke, and pollen.

The CADR ratings can vary from 10 to 450. They are listed in sets of 3 numbers, such as 220/200/190, where the first number is the rating for filtering dust, the 200 is the rating for filtering tobacco smoke and 190 stands for the rating for filtering pollen.

So, if you are looking for an air purifier to tackle your hay fever allergy symptoms, then you should search for an appliance which has the largest CADR rating for filtering pollen (the third number in the set).

If you are looking for a device to clean the area or room from tobacco smoke – you should choose the one with a CADR rating as high as possible for this pollutant (the second number in the set).

And if you need an air purifier to deal with the dust at home, the first number in the CADR rating is the one which should interest you the most.

How to choose the Air Purifier with the right capacity for your needs?

As mentioned earlier, the capacity of the air purifier is the first feature to look for when shopping for such a device.

First, you will need to measure the room you are planning to use it for, and then calculate the total square footage of the room by multiplying the width and length of the room.

If your room is 10 feet wide and 30 feet long, then the total square footage is 10 x 30 = 300 square feet.

So, 300 sq. feet should be the minimum number you should be looking for when choosing an air purifier which can efficiently clean the air it this specific room.

If you are choosing a portable air purifier which you plan on moving around the house, you should measure the largest of the rooms you are planning on using it in, and based on that measurement – choose the capacity of the air purifier.

In case you will be using the air purifier for cleaning the air in several interconnected rooms, then sum up the square footage of all of these rooms, in order to find the total square footage.

It is advisable to always opt for a machine with a capacity which is equal to or higher than the one you need, rather than for one with a lower capacity, because buying an air purifier which is not capable of filtering the air in your specific room will be a waste of money, as it will not work as efficiently as expected.

Also, when buying an air purifier, always think about the placement of the unit before picking one. In order to work efficiently, an air purifier needs to be placed at least 2 to 3 feet away from the walls or from the furniture. Also, you should never place it under a table or hide it under other low furniture, because it will not be able to capture and filter the air properly.

If you are picking a device with an ionizer, then you should ensure that it is set up away from any furniture or walls, and provide with access to 360 degrees around the unit, if you want it to work efficiently in eliminating the pollutants from the air. In fact, the best placement for a unit like this is in or near the center of the room.

When you have chosen the spot where you will be keeping the air purifier, measure the available area, and look for a device which will fit properly there without getting in your way.

What are the other features to look for when shopping for an Air Purifier?

When you start looking for an air purifier you may feel overwhelmed by the number of different features listed in the specifications of each of these devices.

The fact is, some features are more important than others for making the best choice, and other features will only add to the cost without actually being beneficial for your specific needs.

Here are the main and most common features to look for when buying an air purifier:

Pre-filter – this is the outermost filter of the device which captures the largest pollutants from the air, such as dirt and hair, and prevents them from reaching the inner filters. This will help prolong the life of the HEPA or another filter inside the unit, and also will help keep the air cleaner from these common allergens – pet hair and dirt. These filters are usually easy to remove, wash and can be reused.

Adjustable fan speeds – the different air purifiers have different fan speed settings. Usually, they range from 2 to 5 speeds, from low to high. Some devices have a turbo speed option for cleaning a highly polluted room as quickly as possible.

Digital controls – these allow for setting the air quality control more precisely than using a classic push button or rotary dial.

Programmable timer – this is a useful feature which will allow you to set the device to switch on and off in certain time intervals, such as every 2, 4 or 8 hours per day. It is especially useful for ensuring that the air at home is clean even if you are currently not there.

Filter replacement indicators – these are very useful light alerts which will let you know when it is time to replace the different filters in the device. Keeping the filters fresh and clean is key to keeping the air purifier working properly and the air in the room clean too.

Air quality sensors – these sensors will monitor the air quality in the room and will adjust the fan power of the air purifier accordingly. In some cases, these sensors will also let you know when the air in the room is of low quality and when it is clean – in real time.

Anti-microbial treatment – this is a special coating inside the unit which prevents the buildup and growth of harmful microorganisms in the filters and will increase the lifespan of the filters for your device.

Carrying handle – if you are looking for a machine which you will be moving around the house, a carrying handle will make the task much easier for you.

Casters – just like with the carrying handle, if you need a portable air purifier, it helps if it is set on caster wheels, so you can roll it around your home instead of having to carry it.

PlasmaWave technology – this is a special type of ionization which does not produce ozone or omit negative ions and thus is safe for people, pets and asthmatics.

Photocatalytic Oxidation (PCO) – this is an advanced filtering system which utilizes UV light to oxidize chemicals in the air and destroy the airborne bacteria, mold, fungi, and VOCs.

Remote control – this will allow you to control the air purifier without having to go to the device.

Nightlight – this feature can help you locate the device in a dark room, like in a bedroom at night.

Mobile app – smart air purifiers can be connected to mobile apps and will allow you to monitor the air quality status, and the efficiency of the air purifier in real time from your mobile phone or another device.

Additional features to consider when buying an air purifier

Apart from the rated capacity, the ACH and CADR of the air purifier, and the abovementioned features, it is advisable that you consider several additional factors when choosing the best air purifier for your needs and for your budget.

With most air purifiers, the investment in the device itself is just an initial cost, and there are other ongoing costs which will come with the unit and will last for the lifetime of the device.

Here is what to keep in mind when choosing the most suitable air purifier for your budget as well as for your needs and expectations for its performance:

The Maintenance Costs

Air purifiers work efficiently when they are properly maintained. So, before buying an air purifier for your home, make sure you check how much this maintenance will cost you in the long run.

Air purifiers which use True HEPA filters and activated carbon filters will most likely require routine replacement of these filters. Over time, these filters will become clogged with the pollutants they have captured and will not be able to filter the air anymore.

The filter life depends on the air quality in the room, and how often the device is used. It also depends on whether the device has a pre-filter which can prolong the life of the internal filters, as well as whether it has an antimicrobial coating which protects the filters from growing mold, fungi, and other harmful microorganisms.

Make sure you check the manufacturer’s recommendations for the period in which the filters will need to be replaced, as well as the cost of the replacement filters.

Most filters have lifespans from 3 months to a year, and their cost can vary from $15 to $50 and more.

If you choose an ionic cleaner, you won’t need to worry about replacement filters because they do not use degradable filters which need to be replaced.

In some cases, the air purifiers might have HEPA or other filters which can be washed and reused, but this is usually the case for smaller sized and less powerful units.

The noise level

This may not be the first feature which pops in mind when you are shopping for an air purifier, but keep in mind that some air purifiers have powerful fans which draw the air in and out, and which may be quite noisy. This can be especially disturbing if you are sensitive to noises, or if you are a light sleeper and want to use the unit in your bedroom.

The slower the fan speed – the lower the noise level.

You should check the noise ratings for the air purifier of your choice, to ensure that it will be tolerable for your needs.

Also, if you pick a device which is capable of cleaning an area larger than the room it is intended for, you can run it at lower speed levels and still get the air cleaning efficiency you expect.

If you buy a less powerful device, chances are that you will need to run it at the highest speed at all times in order to make sure that the air is purified and filtered properly. And this means – more noise.

Ionic air cleaners do not use fans, so they are completely silent.

Energy Consumption

All air purifiers need electrical power to operate. Since it is recommended that the device runs continuously in order to ensure that the air quality in the room or area remains healthy and good, then it makes sense to check the power consumption of the device as well.

Most of these devices use 5 to 200 watts of electrical power. It is advisable to choose an air purifier which has an Energy Star rating and is energy saving.

The reputation of the manufacturer

Since air purifiers are not inexpensive, it makes sense to invest your hard earned money in a device of higher quality and made by a reputable manufacturer, if you want to be making a wise and long-term investment.

Unfortunately, some cheaper devices made by unknown manufacturers may not be able to clean the air in the room or house as expected and thus you will be wasting your money.

Thankfully, there are a lot of trustworthy manufacturers from the USA and Europe where there are strict standards and regulations for these machines.

Here are some of the manufacturers and brands of air purifiers that you can trust:

  • Austin Air
  • Alen Air
  • Blueair
  • Coway
  • Fellowes
  • Envion
  • GermGuardian
  • Honeywell
  • Hamilton Beach
  • Homes
  • Mammoth
  • Rabbit Air
  • O-ION
  • Winix
  • Whirlpool

The Warranty for the Air Purifier

As mentioned before, a good quality air purifier can be a serious investment, which is why it makes sense to look for the warranty offered by the manufacturer.

Make sure you check which parts and labor are covered by the warranty and for how long so that you can make sure that you are making a sound long-term investment.

FAQs about buying an air purifier

Here are some of the most common questions which consumers ask when shopping for an air purifier:

What type of air purifier do I need?

The answer to this question depends on which types of air pollutants you trying to get rid of, and why.

If you want to remove allergens such as pollen, mold spores, dust, pet dander, and tobacco smoke, then you should opt for a True HEPA or an ionic air cleaner.

If you want to get rid of smells, gases and fumes look for an air purifier with an activated carbon filter.

If you want to sanitize the room by killing the germs, viruses, and bacteria you should opt for a UV-C light air purifier.

How often should I switch on the air purifier?

If you want to have consistently clear air in the room or area day or night, then it is advisable to run the air purifier 24/7.

When you first switch it on, run it at the highest fan speed, so that it cleans out the air faster, and once that is done, adjust the setting to medium or low in order for the unit to keep the air clean continuously.

Some air purifiers have automatic sensors and will automatically switch to a higher setting if air contamination is detected.

In case you will be using the air purifier in a closed room such as a bedroom, then you can power it on only when it becomes time for sleep.

What kind of area can an air purifier cover?

All air purifiers are different, so make sure you check the maximum square footage rating of the unit before purchasing it. You should look for a device with a rating which is equal to or larger than the room square footage you need it for.

Do I need more than one air purifier?

This depends on your specific needs. If you want an air purifier for your bedroom only, then you only need one. In case you have several rooms which are not interconnected but you want the air in them filtered too, then you will need more than one air purifiers.

Some portable air purifiers can be carried or rolled around the house, so you can move the air cleaning system with you from the living room to the bedroom when you are going to sleep.

How do I know when it is time to replace the filter?

Some air purifiers have nifty filter replacement indicators which will let you know when the filter is clogged and needs replacement. In case your unit doesn’t have such an indicator, check the recommendations by the manufacturer and add the replacement time to your annual calendar, or schedule

Should I keep the window open when I am using an air purifier?

No, an air purifier needs a tightly closed space in order to clean the air efficiently. This means you should keep the windows and doors closed for maximum efficiency and if you want to air inside to be completely pollutant-free.

My area is not polluted, do I still need an air purifier?

Yes, because not all pollutants in your home come from outside. In fact, your cleaning detergents furniture materials, the paints and construction materials, the pets, the smoke and fumes, the mold, dust mites, and more pollutants are created within your home.

Are air purifiers safe for me and for my pets?

Most air purifiers are completely safe. The sole exceptions are the ones which produce ozone and which can cause irritations for people with asthma, coughing, chest pain and lung damage. Ozone is harmful to people and for animals as well.

How to properly use an air purifier

In order to get the best results you should use the air purifier as follows:

  • Allow it to run 24/7
  • Keep it in one place without furniture on top or with walls directly behind it
  • Close the doors and windows in the room
  • Check and replace the air purifier filters as recommended by the manufacturer

Is buying an air purifier a wise investment?

Yes, it is a wise investment, but only if you buy an air purifier which is suitable for your specific needs and for the room size you need it for.

If you need an air purifier to alleviate asthma or allergic symptoms, investing in a good quality air purifier can actually save you money in the long run for medication and for doctor’s visits.

It will also help you and your family to stay healthy and have lesser sick days due to infections and viruses, or other health issues caused by harmful air pollutants.

Also, an air purifier can keep your home free of mold and tobacco smoke and odor which is something that raises the value of your real estate as well.
