Things to know before buying air purifier


Maintaining an air purifier is easy. You slip out the old filter and slide in the replacement. Some use conventional fiberglass filters; others are pleated or electrically charged to pick up particles. Air filters generally include a range of standard sizes, with a few that can adapt to fit different-sized 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.

Terms to Know

MERV: Many whole-house filters list a minimum efficiency reporting value (MERV), developed by ASHRAE (formerly the American Society of Heating, Refrigerating and Air-Conditioning Engineers). The higher the number the finer the filtration. The top performers in our tests typically have a MERV higher than 10.

MPR: This is the Microparticle Performance Rating, developed by 3M. It rates the filters on the ability to capture airborne particles smaller than 1 micron. The best filters have an MPR between 1,500 and 1,900.

FPR: Home Depot uses its own rating system, on a scale of 1 to 10, called the Filter Performance Rating. The higher the number the better it filters.

HEPA: Fitting a furnace with an electrostatic filter, which uses an electrical charge to help trap particles, or a high-efficiency particulate air (HEPA) filter can reduce the amount of dust blown through the heating system. That might help people with asthma and other chronic lung diseases, but there’s little evidence that other people need such filtration.

Final note

Air filters, in general, do a good job of clearing the air. But do they actually make you feel better? The medical verdict is still out.

According to pulmonary specialist Andrew Filderman, no controlled studies have been done on the subject. “We know these things filter the stuff, but we don’t know if it helps,” he says. “It’s difficult to prove because there are so many provocative things in the air, and you don’t always know what’s causing the problem.” Dr. Filderman adds that while some allergic or asthmatic patients report benefits from air filters, the evidence remains anecdotal. “If source control and ventilation don’t help,” he says, “it’s not unreasonable to try a filter.”
