The new CAP1200-UVP from Abatement Technologies, Inc. (Duluth, GA), designed for residential and light commercial applications, joins the company’s line of central air purifiers. It handles 4- to 10-ton systems, delivering 50 to 80 clean air changes per day, says the company.
The 99.97%-efficient HEPA final filter captures airborne contaminants, the company says, while the UV Plus emitter produces germicidal UV to control airborne bacteria and viruses, plus a controlled level of ozone to impair mold and fungal growth, and chemically break down VOCs and unpleasant odors.
Research Products Corp. (Madison, WI) announced that recent tests performed at an independent laboratory indicate its Aprilaire electronic air cleaner, Model 5000, can remove 80% of airborne particulate ranging from 0.02 to 0.3 microns in size — the same size as airborne viruses such as influenza, measles, and the common cold.
Research Triangle Institute, a nonprofit organization located in North Carolina, performed the test using an ultra-fine KCI aerosol, 0.012 to 0.34 microns in size.
Bruce Darkow, spokesperson for the company, said, “We know of no other residential air cleaner that even comes close to delivering this kind of performance on particles so small.”
