Rowenta's new Intense Pure Air has a four-stage air filter that offers an unusual level of protection from airborne allergens and pollutants in your home. 

Quiet and easy to maintain, the Intense Pure Air traps up to 99.97 percent of the particles in the air starting with a pre-filter for large particles like dust and animal hair. Next comes an Active Carbon filter for odors, gases and volatile organic compounds (VOCs) found in some paints. A HEPA filter then captures the smallest particulate matter like mold, pollen, and bacteria.

The fourth stage is a patented NanoCaptur fiter which captures and destroys formaldehyde, a particularly unhealthy chemical which the U.S. Centers for Disease Control's Agency for Toxic Substances and Disease Registry (ATSDR) calls a common indoor air pollutant that can be released by building materials, textiles, and furniture; it also notes that most air filters do not help lower formaldehyde levels in homes. (Formaldehyde is more likely to be a problem in homes built after 1990, as they are better insulated and have fewer air leaks.) 

Other features include an automatic quiet mode at night, an intelligent filtration system with two pollutants sensors that inform the user of pollution levels and automatically adjusts the air speed accordingly. The Intense Pure Air is quiet, running at 22 decibels on the lowest setting (about as loud as a whisper) and 45 decibels on the highest (falling somewhere between a library and a conversation at home). The largest model has a suggested retail price of $379 and is available from 20/20 Special Markets.
