If you’re sensitive to the air around you in your home, chances are you’ve heard of an air purifier before. These devices take in the air surrounding you, filter it out, and put it back without all the dust, mold, pollen, and more that can cause harm.

But are they just for those with sensitivity and allergies? Nope! These are great devices for anyone to have in their home. If you’re new to them, there are a few questions you likely have before actually picking one up for yourself. Let’s talk about a few of them.

What do air purifiers do?

Air purifiers take in air from their surroundings and run it through a filter or series of filters. These filters take out a majority of the particles in the air that can harm your lungs and cause allergies to flair.

Homes with lots of dust, mold, or pollen are common places to use an air purifier. Once the harmful particles are filtered out, the air is pumped back out into your home for you to breathe safely.

Are air purifiers loud?

Many of them are designed to be extremely quiet. Typically they range from 20-50 decibels while in use depending on how hard you have them working. For reference, 20 decibels is quieter than a whisper, and 50 decibels is about the same level as a quiet refrigerator.

So regardless, you shouldn’t notice much noise at all while in operation. That being said, some of the options featured in our list have modes that produce white noise. This helps those who like a bit of background noise while going to sleep.

Can an air purifier purify my whole house?

Most likely the answer will be no. These featured purifiers all cover maximum areas of around 1000 square feet. For the most effective use, you may want to put your purifier in your larger, more commonly used rooms such as a bedroom or living room.

Why do I want a HEPA-specific air purifier?

HEPA stands for high-efficiency particulate air filter. These standards are set by the US Department of Energy. To be considered HEPA, the filter must remove at least 99.97% of particles such as dust, pollen, mold, bacteria, and other airborne particles. You would want to use a HEPA air purifier because of how effective it will be at removing particles and purifying the surrounding air.

An important aspect of any air purifier is the level of sound it produces. The WELOV P100 is library quiet, operating at as low as 23 decibels while in sleep mode.
