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, you still need to remember what wooed you to buy the machine.

Besides, it maybe this is your first time buying a whole-house air purifier. If so, this part will be of help to you. It will help you decide 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 manufacturers are helping you with this, making it easier for you to decide wisely.

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

Perhaps you have seen that this review shows the most petite square feet to 600 while the most significant is 3500.

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

• Filter Type

Filtration is vital and differs from one whole house cleaner to another. I initially tried to speak about this subject when I pointed out that the best whole-house air purifier uses four primary filters.

However, perhaps you have seen that some high-end air purifiers for the whole house use various 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 on how effective the air purifier’s filtration system is.

• Noise Level

No one can withstand a sturdy, nice-looking, noisy whole-house air purifier. Primarily, many homeowners prefer the air purification system to work at night. If you agree with me, 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 at its low mode and a maximum of a meager 53dB at the high mode.

If you have small children, an older adult, 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. You can choose the ideal whole-house HEPA air purifier that can clean the air in your home.
