Today’s air tight, energy-efficient homes keep you warm during the winter and cool in the summer. On the downside, your home can’t breathe. Air filtration machines—or air purifiers—will not only bring fresh air inside, they will improve air quality, reduce dust and relieve allergy and asthma symptoms.
It is important to note that not all units are beneficial or healthy. Here are some things to keep in mind when buying air purifiers.
HEPA Filtration—High Efficiency Particulate Air filtration is one of most efficient air purifiers for removing allergens and small particulates. These filters are similar to those that trap dust in your vacuum. They can eliminate 99.97 percent of air pollutants .3 microns or greater from the air. HEPA filters also get rid of tobacco smoke, dust, mold spores, animal dander and pollen.
Clean Air Delivery Rate (CADR)—This seal program was developed to help consumers select air purifiers. Based on the cubic feet of air a purifier can filter per minute, the higher the CADR number, the faster your air gets cleaned.
Dust Sensor of Air Quality Monitor—Some air purifiers are equipped with automatic sensors to determine how polluted the air is. They also can automatically adjust the unit’s cleaning speed. Unfortunately, you won’t have as much control over how much energy your air purifier uses or its noise level. These monitors are a plus if the room that houses them isn’t occupied.
Ozone—Stay away from air purifiers that are billed as air fresheners. They produce ozone, a sweet smelling fragrance that is a known lung irritant.
Asthma and Allergy Friendly—This certification from the Asthma and Allergy Foundation is fairly new. Purifiers must prove that they reduce, not redistribute, allergens.
UV-C Sanitizer—This ultraviolet light kills bacteria and eliminates odors caused by your pets, smoke or cooking.
