Air Cleaners and Dust Removal

Air purifiers work best on the tiny particles that remain airborne

by Bob Cobe, AllergyBuyersClub.com Staff

Many customers buy an air purifier to "remove dust" from their rooms and are disappointed when they still see dust.

An air purifier can remove only the particles that remain airborne long enough to go into the purifier. The dust that you and I (and the customers) see consists of large particles that have weight, which will cause many of the larger particles to "land" before they arrive at the purifier. Some particles will make it into the machine, but many, many will not.

Air cleaners work best on the tiny particles that remain airborne and float for a long time. These tiny particles, well below what we can see, are the ones that pass right through the hairs and mucus in our noses and lodge in the lungs. They are the size that bother us the most even though we can't see them. So while it may seem that an air purifier is not removing much dust, it is working just fine on the particles that actually bother us.

The heavier dust that lands on furniture needs to be dusted or vacuumed with a hepa vacuum cleaner to be removed.
