What is a whole house air purifier?

Air purifiers for whole homes are devices which are either connected to your existing HVAC system or are standalone units which are capable of filtering the air in the entire house or apartment.

The whole house air purifiers which are installed within the HVAC system do not require any power and clean and filter the air as it passes through the system when you are cooling or heating your home. The standalone air purifiers for whole homes do require to be plugged in and are portable, so you can move them from one room to another when necessary.

Whole home air purifiers are designed to be able to cover the entire area of your home, and to remove all air pollutants, such as dust, dust mites, pet hair or dander, germs, viruses, mold spores, mildew, fungus, fumes, smoke, pollen, VOCs, odors and all other airborne pollutants flying in the air in your home.

The idea is to minimize or eliminate the allergens or other harmful pollutants which can cause adverse reactions in people with allergies, asthma, weak immune systems, as well as ensure that you and your family are breathing healthy, clean and fresh air at all times.

Should you buy an air purifier for the whole home?

An air purifier of this type is indispensable if you or a family member has a dust or pet allergy or suffer from hay fever, asthma, COPD or other respiratory problems.

Also, if you live in a heavily polluted area, a whole house air purifier can ensure that you will be breathing clean and healthy air when you are home.

Such air purifiers are also very useful for homes with pets, with smokers, with small children or with elderly people. These devices can successfully eliminate viruses and germs and bacteria, as well as harmful fumes, VOCs, carbon monoxide, mildew, mold, fungus and bad smells from the air.

A whole house air purifier will also save you money and space for having to purchase separate smaller ones for the separate rooms and areas in your home. If you decide to install an air purifier in your HVAC system you will not need to use up any space at all, and you won’t need to power it either.

Most of these devices are designed to last long and have filters which don’t need to be replaced as often as those of smaller air purifiers.

Most good quality air purifiers for whole homes can work 24/7 and usually, operate quietly. Many of the standalone plug-in air purifiers have timers so you can set them to work for a limited time as well.

All of our top picks for the plug-in variants have sensors and auto mode, which means that you can let these units do the thinking and the adjustment for you, as they will automatically turn up the speed when low-quality air is detected and will decrease the speed when the air is fresh and clean.

What kind of area coverage do they provide?

The different types and models of air purifiers for entire homes offer different coverage. They are much more powerful than regular room air purifiers, and in some cases can clean the air efficiently in homes as large as 3,000-4,000 square feet and more.

A rule of the thumb is to choose a whole house air purifier which has a capacity which is slightly larger than the size of your home so that you can be sure that it will work effectively and will clean the air properly.

Some other performance metrics and terms to keep in mind

CFM – this is the capacity of the air purifier’s airflow in cubic feet per minute. The CFM will give you an idea about how many cubic feet the air purifier can clean per minute. The higher the CFM, the larger space it can clean. To figure out what CFM to look for, measure the size of your home, and choose a unit with a CFM equal to about 100 CFM per every 250 square feet.

MERV – this is the Minimum Efficiency Reporting Value used to determine the efficiency of a filter to trap airborne pollutants and particles. The higher the MERV rating is – the more efficient the filter is. MERV ratings start from 1 and reach up to 15, with MERV 16 being able to capture more than 95% of all airborne particles sized as small as 0.3 microns.

HEPA – High-Efficiency Particulate Air is an air filter which needs to meet the set standards and to remove up to 99.97% of airborne particles (in the USA according to ASME), and up to 99.95% (in Europe) from the air with the smallest particles trapped by the filter being as small as just 0.3 microns.

Features to look for when buying an air purifier for your whole home

You should look for the following features when you are shopping for a whole-home air purifier:

  • Its coverage – choose a purifier which has a capacity slightly greater than the actual size of your home
  • The filter type – choose the type of filter or filtering systems depending on your specific needs. HEPA filters are excellent for allergic people or those with respiratory problems, ozone generators are great if you want to sterilize the house and remove germs, viruses and other harmful pollutants or nasty odors, activated carbon filters are very efficient for removing smells and smoke, and pre-filters trap the pollen and larger airborne particles. MERV filters are rated by their ability to filter the air – the higher the number – the better the filtration.
  • The air change rate – this is the number of times that the air purifier completely filters the air in the house per hour. It is a good idea to invest in a more powerful model so that you can use it at a lower speed and thus lower the energy consumption and the noise it makes.
  • Clean Air Delivery Rate (CADR) is the amount of purified air which the purifier can deliver. The larger your home is – the higher the CADR should be if you want the air at home to be fresh at all times.
  • Smart sensors and automatic mode – this is very useful if you want the air purifier to adjust itself in accordance with the quality of the air at home instead of having to adjust the settings manually and to keep monitoring the air quality yourself.
  • Budget – of course, your set budget for an air purifier for whole homes is essential as well. The top of the line air purifiers in this range can be quite expensive, but there are budget-friendly options as well. Also, check how much the replacement filters cost and how often they will need to be replaced so that you can calculate this cost as well. Plus, look for energy saving units which will not add up too much to your electricity bill too.
