What Is A Whole House Air Purifier?

As the name suggests, a whole house air purifier is a home appliance that has the ability to clean and purify the air in the whole house. As opposed to other air purifiers, most of which I have addressed in the past, the best whole house air purifier remains the best in removing the polluted air from a home.

According to the Environmental Protection Agency (EPA), contrary to what many people think, the reality is that indoor air can be polluted up to 5x compared to outdoor air. For this reason alone, you need a whole house air purifier system that can be able to remove polluted air of this magnitude.

In order to help whole house air purifiers do their work effectively, manufacturers use a variety of filters. The four main filters you can find in the best whole home air cleaner include:

UV filters – these high-end filters use ultraviolet light that has the ability to kill all types of mold and bacteria.

Electronic filters – with the help of all-time electrostatic field, these filters have a unique ability to capture the tiniest particles.

Media filters – unlike electronic filters, media filters are renowned for their ability to capture and destroy large particles.

Electrostatic filters – these filters use charged particles, after which they are able to kill germs and bacteria that may not be visible to the naked eye.

How Does a Whole House Air Purifier Work?

Although you’ve seen the four main types of filters whole house air cleaners use, you may still ask, how does a whole house air cleaner work? Well, it is simple.

For a whole house air purifier to do its job, it must be integrated with your house’s heating as well as cooling system. The aim of doing this is to be able to control the air quality of your house at the same time you are adjusting the temperature of the house.

Depending on the type(s) of filters that are in the machine, the air in the house will heat or cool thus kill mold, bacteria, remove fumes, and destroy all harmful particles from your house.

Features To Consider While Choosing a Whole House Air Purifier

If you have used a whole house air purifier, you know the benefits the appliance has given you. Nonetheless, if some time has passed since you got your home use appliance, chances are you’ve forgotten what wooed you to buy the machine.

Besides, it maybe this is your first time to buy a whole house air purifier. If so, this part will be of help to you. It will help you make a wise decision on buying the best whole house air purifier.

  • Coverage Area

This first and fundamental factor will help you determine the type of home air purifier you will buy. The beauty is manufacturers are helping you in this, making it easier for you to decide wisely.

Most air purifier for home manufacturers do not leave it at a chance. Whether it is on the package or on their websites, they have indicated the number of square feet each air purifier for the whole house will cover.

Perhaps, you have seen that this review shows the least number of square feet to be 600 while the largest being 3500.

If you intend to use the best whole house air purifier for a large house that has among other things, has a basement, pets, and several rooms, you need the best whole house filtration system that can clean air in a large area.

  • Filter Type

Filtration is key and differs from one whole house purifier to another. I tried to speak about this subject at the beginning, when I pointed out that the best whole house air purifier uses four main filters.

However, perhaps you have seen that some of the high-end air purifiers for the whole house use a variety of filters in their air filtration and purification process. Whether it is photocatalytic oxidation, ionization, UV, or even the use of ordinary permanent filters, your primary focus should be how effective the air purifier’s filtration system is.

  • Noise Level

No one can withstand a sturdy, nice-looking, yet noisy whole house air purifier. Largely, many homeowners prefer the air purification system to work at night. If you agree with me on this, then it beats logic that you’d go for a house air filter with the lowest dB levels.

From my review, I can see one with as low as 10dB when at its low mode and a maximum of a meager 53dB when at the high mode.

If you have small children, an elderly person, or someone struggling with an ailment in the house, you will do better to go for a whole house air purifier with UV light that is almost silent whether at its high or low mode.

Conclusion

With the availability of the best whole house air purifiers in the market, you do not have to put your family’s health and that of your pets at stake. Take your time to choose the ideal whole house HEPA air purifier that can be able to clean the air in your home. Whether it is the recommended hospital grade whole house air purifier or a small air purifier for a single room, ensure it cannot disturb your loved ones when it is working.
