For good indoor air quality

Pollutants that most often affect indoor

air quality (IAQ) are either biological

(living organisms, like mould, bacteria

and dust mites) or chemical (usually

from outside air, indoor combustion,

and common household products). To

improve IAQ, homeowners are advised

to both prevent them from entering the

home and to eliminate them from the

inside. A proper system can do both. In a

sealed home environment, most incoming

air can be directed by circulation fans

through a mechanical filtration system

that eliminates the bulk of common

airborne offenders. Even if windows or

doors are frequently opened, the air can

be channeled through the system. In

addition, electronic air cleaners can be

very effective at removing pollutants from

the air in specific rooms. A third portable

type called ion generators are also

common, but they should not be used if

they create harmful ozone gas as a byproduct,

as it can make breathing all the

more troublesome. If you’re unsure of the

best treatment for your home, consult a

reputable IAQ professional.
