Indoor Air Purifiers
Indoor air quality is becoming increasingly important topic in everyday life. The Environmental Protection Agency (EPA) estimates that indoor air pollutant levels may be two to five times higher than the pollutant levels outdoors, which raises some concerns. The concerns are elevated by the estimate that average American spends up to 90 percent of her time indoors. Indoor air pollutants include tobacco smoke, pollen, mold, dust and animal dander. Air purifiers may bring some relief to the situation. Main differences between the available indoor cleaners include the efficient volume of air the unit can purify, the technology used, and the efficiency of the purifying process. As for the commercial purifiers, they are typically able to purify larger volumes of air than residential purifiers or similar volumes but with better efficiency. Many of the newer technologies, such as ULPA (Ultra Low Penetrating Air) first have applications in the industrial environment, and slowly become available to the residential market. The industrial purifiers cost a lot more due to the fact that their production numbers are much smaller than the ones for residential purifiers. Indoor Air Purifiers - Manufacturers A good place to start comparing indoor air cleaners is cadr.org, which is a web site by Association of Home Appliance Manufacturers (AHAM) for CADR (Clean Air Delivery Rate), a measure to compare air purifiers. The web site has a good list of manufacturers, which includes both commercial and residential air purifier manufacturers. You can easily compare each manufacturers' products in terms of CADR, a measure which you'll find one for tobacco smoke, one for pollen and one for dust. The CADR indicates volume of filtered air delivered by an air cleaner. |
