For whole-house filters, our recommended models did best at filtering dust and pollen without impeding the airflow of forced-air heating and cooling systems. The worst models weren’t terribly effective at any speed.
Whole-House Air Purifiers
If you already have forced-air heating and cooling, popping in a specialized filter is an inexpensive alternative to a built-in home unit. Basically, it acts as a furnace or central A/C filter that you replace regularly.
It’s easy. You slip out the old filter and slide in the replacement. Some are conventional fiberglass filters; others are pleated or electrically charged to pick up particles. (Note that the electrically-charged versions are not actually electrically powered, even when they have names like Electroclean, and they don’t produce ozone.)
Whole-house air filters generally include a range of standard sizes, with some that adapt to fit different-size filter-box or return-air openings.
For thicker filters to fit, you may possibly need to have your ductwork modified by a professional.
The filters must be replaced every one to three months.
Prices: From $20 to $80 per filter
