5 Best Basement Air Purifiers To Keep Dust, Allergens And Odors At BayVIA MERCHANT

Good air quality has always been critical, even before the world was hit with the coronavirus. Unfortunately, basements are often neglected in favor of upstairs living areas and bedrooms. The good news is that adding a basement air purifier to your home’s subterranean space is easy to do and relatively affordable.

Often dank and humid, basements (even finished ones!) are known to harbor dust, mold and other airborne pollutants. Air purifying machines effectively eliminate the threat of microscopic particles, impurities and allergens that can lead to severe health problems—especially for those suffering from asthma or allergies. Basement air purifiers are also excellent for removing unpleasant, musty odors due to excess humidity, a leaky sewage line or a faulty sump pump.

With families spending a lot of time “below ground” these days doing laundry, tinkering on DIY projects or playing ping pong, air purifiers are more important than ever. But you can breath a (clean) sigh of relief: We found the best basement air purifier to suit everyone’s needs.

How do air purifiers work?

Air purifiers are electronic devices that sanitize air to remove impurities and pollutants. They work by using a fan to suck air in and send it through one or more filters. The filters capture and neutralize the particles as they pass, pushing the clean air back out into the living space. Additionally, some have ionizers to help improve air quality.

What’s the difference between an air purifier and a dehumidifier?

Air purifiers do just that: purify the air. Dehumidifiers, on the other hand, draw humidity out of the air. Drying up a moist basement suppresses the growth of unhealthy mold and discourages bugs such as silverfish, cockroaches and spiders from moving in.

Do air purifiers work for removing smell and mold in basements?

Does your basement have disagreeable household odors? To stamp out bad smells, a basement air purifier with a carbon filter is a must.
