Why do you need a salt-free water softener?
If you have water that has high contents of calcium, magnesium, magnesium carbonate or other minerals, this means that you have hard water.
Some signs that the water in your home is hard, include – the soaps not lathering properly, rings in the sinks or bathtubs, spots on the dishes, stains on the ironed clothes, a reduced water flow, dingy-looking laundry and others.
While there are other types of water softeners, salt-free ones do not add sodium to the water, and thus the water is healthier for drinking and cooking, as well as better for the environment.
Plus, salt-free water softeners do not actually remove the minerals from the water which runs in your house, they just prevent it from sticking on and building up on the inside of the pipes, in your appliances, and on your bathroom and kitchen furniture.
The minerals which remain in the water are actually good for you, for your pets, and your plants.
Salt-free water softeners are also easier to maintain and a superb addition to the whole house water filter system.
Features to consider when buying the perfect salt-free water softener
Since many of the salt-free water softeners are quite expensive, buying a system like this needs some preliminary planning to ensure that you are making a wise long-term investment.
Here are some tips on how to choose the perfect salt-free water softener for your needs, as well as the main features to look for.
Test your water for your grain rating
Testing your water with a home test kit or by using a professional to do it is essential if you want to buy a system or device which can actually help make the water in your home softer.
A home water test may also help you identify other potentially harmful and dangerous issues like high levels of bacteria, viruses, chlorine or other contaminants in your water.
The test results will show you the numbers of grains of the different minerals are present in a gallon of water.
This will give you the grain rating you should look for when shopping for a salt-free water softener.
If you use municipal water, you can ask the city to provide you with the grain rating per gallon, instead of doing the test yourself.
The difference in the grain ratings of city and well water can differ very much. In most cities, the allowed tolerance is for 15 grains per gallon of water, while some wells can contain water with 40 grains or more per gallon.
Most of the salt-free water softeners have a capacity to handle 15 grains per gallon, but if the grain rating of your water is higher than that, you may want to opt for another type of water softener or one with a higher capacity.
The water flow rate
Since the salt-free water softeners do not backflush the materials filtered, and instead turn them into non-adhesive crystalized ions which remain on the surface of the filter, the water passing through them will retain its continual up flow.
You should choose the water softening system in accordance with the water consumption and flow in your home.
While some of the systems can cause a drop in the water flow when several appliances or faucets are turned on, others have a higher water flow rate and will not have an impact on the water flow in the house.
A rule of thumb to follow is that one member of the household uses 4 gallons per minute. You should add another 1-2 gallons per person, to get the total water flow rate you will need.
In other words, the more people living in your home – the higher the water flow rate you will need.
For example, if four people are living in your home, you should opt for a salt-free water softener with a flow rate of 7 to 10 GPM.
The maximum pressure
The different salt-free water softeners have different maximum pressure rates. Choose a system that does not require too much pressure, and which will decrease the overall water pressure in your home.
As you can see from our list, the water softeners can vary in size quite a lot. Make sure you have the space to install your salt-free water softener before buying it.
The technology used for softening the water
There are 4 basic types of water softeners on the market. It is essential to understand how which one works, and what its pros and cons are so that you can choose the most suitable type for your needs.
In order to understand the four different types of salt-free water softening systems, it is essential to note that as mentioned previously, these devices do not actually remove the minerals from the water.
They simply convert them into a form that is not harmful to the pipes, the plumbing, the hair, clothes, skin, appliances, and for the aesthetics and cleanliness of your sinks, toilets, bathtubs and others.
The fact is, mineral grains are good for our health. They are good for our pets and good for our plants as well.
So, these water softeners simply remove the negative impact these minerals have, instead of eliminating them.
To do so, salt-free water softeners use several different methods.
Here are the main types of salt-free water softeners which you can choose from:
Use of Polyphosphates for softening
Polyphosphates are perfectly safe chemicals that are added to the water. They coat the minerals in the water in a way that prevents them from sticking to the pipes, appliances, furniture, clothes and to you.
These chemicals do not remove the actual minerals from the water, they just reduce their harmful effect and the buildup of scale in the pipes on the heating elements of your appliances and elsewhere.
This type of water softening system is straightforward and has the sole purpose of softening the water. It will not resolve iron and sulfur contaminations from wells, and will not remove the chlorine from treated municipal water.
These systems will not remove bacteria, pesticides, or herbicides.
They usually have filters that will capture the larger particles and will allow the coated calcium and magnesium particles to pass through.
Systems like this do require regular cleaning as well as refilling with polyphosphates.
They are highly efficient in removing the buildup in your pipes and are a great option for the first step in a more complex water softening system.
Complete filtering systems
Apart from softening the water in your home, systems like this will filter out a variety of other contaminants from your water as well.
They are more complex than polyphosphate systems.
The water is softened by filtering units that crystalize and coat the mineral grains and thus preventing them from sticking to the pipes or to anything else.
The systems with additional filters can also remove chlorine and chloramines from municipal water, or herbicides, viruses, pesticides, and bacteria from well water.
This type of salt-free water softeners is the most recommended option for homes that use city water, although they can be very efficient for softening well water too.
But if your water comes from a well and has a very high grain rating, you may want to opt for another water softening system or pair this one with another technology.
The full filtering systems for softening and filtering the water are an excellent solution, but they do require regular filter replacements at about 6 to 12 months, which will add to the overall cost of maintaining such a system.
Electro-Magnetic softening systems
The electro-magnetic salt-free water softeners are amazingly easy to install. You just need to plug them in and connect their coils to a pipe at the entrance of the home, and it will do the rest.
These nifty and affordable devices send electromagnetic waves through the pipes in your home. As a result, the waves cause the mineral grains to magnetize and send them into the water, instead of clinging to the pipes and causing a build-up.
These water softening systems are suitable for homes that have a mineral grain rating of 15 or less per gallon. They are also perfect as an addition to another water softening system and can be installed at the end of the filtering and softening process for the best results.
These compact devices do not require that you cut any pipes, or do any plumbing. Nor do they require costly filter replacements or polyphosphate refills.
They use up very little electrical power, but they need to be plugged in constantly.
Magnetic water softening
These water softening systems are similar to the electromagnetic ones but do not use electricity to magnetize the mineral grains.
Instead, they use strong magnets which are attached to the pipes, and which magnetize all of the minerals passing through them.
Plus, over time, it will help loosen the buildup on the pipes and will flush the particles stuck to the pipes through your plumbing system.
The magnetic water softeners are the least effective ones, but they are permanent and require no maintenance whatsoever.
They are suitable for the final stage of a whole water softening system.
Chlorine filtration and reduction
If your home is supplied with chlorine-treated water, you should check out whether the salt-free water softener of your choice reduces the chlorine in the water.
It helps to get the water tested before buying and installing a system like this so that you know just how much of the chlorine you need to be filtered out and find one which meets your needs.
The operating temperature
Depending on where you live and also on where you are planning to install your salt-free water softener, you should pick a system that is capable of working in the temperatures there, as well as the water temperatures.
Check out the characteristics of your water softener to ensure that it will work properly at your given conditions.
Ease of installation
If you are a DIYer and would like to install your salt-free water softening system by yourself, it will help to check out whether it is sold with a detailed installation guide or DVD, and also if the package includes the parts you will need for the installation.
If you have picked an electromagnetic or a magnetic system, then you can easily install them by yourself, as they do not require any plumbing whatsoever.
But if you are opting for a more complicated system which requires cutting pipes, and other more complicated tasks, you may want to hire a professional plumber to do the job to prevent any incidents and to ensure that the system is installed correctly and it will do the job you have purchased it for.
Keep in mind that full filter systems will require regular filter replacements, and polyphosphate systems need to be cleaned and refilled periodically.
Check out how often you will need to buy replacement filters, polyphosphates, or will need to clean or otherwise maintain your home water softening system.
This will give you an idea of what kind of ongoing costs you should be prepared for, as well as the efforts which will be required to keep the water softening system working properly.
The materials used
If you have the chance, always check out whether the parts of your salt-free water softener which come into contact with the water, are made of safe materials. You should opt for BPA free materials, to reduce the risk of cancer caused by the carcinogens found in some plastics with BPA.
Stainless steel and BPA-free plastic are the best and safest options to opt for when choosing the materials because you will be using this water for drinking, cooking, washing your dishes, clothes and yourself.
As with any other purchase of expensive products for the home, it is essential to check out what kind of warranty is offered by the manufacturer, as well as what exactly is covered by this warranty.
Some of the products on our list come with warranties that will last the lifetime of the system, and others have shorter warranties, or offer money-back guarantees.
It makes sense to choose a salt-free water softener which comes with a more extended warranty which includes covering more problems, defects and others because a water softening system is supposed to be a long-term investment.
Which is better – salt-based or saltless water softeners?
There is a big difference between salt-based water softeners and salt-free water conditioners.
The systems which use salt to make the water softer replace the magnesium, calcium and other minerals into softer minerals – sodium and potassium. They do actually remove the minerals from the water.
The salt-free water softeners change the form of the mineral grains into ones that do not stick to the surfaces of the pipes, appliances, clothes and so on. But the minerals remain intact in the water, so the process should more appropriately be called water conditioning or descaling, and not softening.
Both types of softening have their pros and cons.
The advantages of the salt-based systems are that the water will give you a cleaner feeling when you are showering or bathing, the soap will lather more, your clothes will retain their bright colors after washing, and there will be no unsightly buildups on your sinks, toilets, and others.
The disadvantage is the regular refill of salt, as well as the presence of higher levels of sodium in the tap water, which can be harmful to people on low-sodium diets.
With the salt-free systems, the main advantage is the low maintenance required, and that these systems do not wastewater, and use no chemicals and salts. The water will not feel as slick and slippery, and the results may not be as apparent on your skin, clothes, and furniture.
