Blueair Air Purifier with Remote Control

Its Best Features
The Blueair 403 Air Purifier is the upgraded version of the now discontinued Blueair 402 Air Purifier.  It offers 4 filtration speeds that allow you to choose the rate at which your air is cleaned. So when life come at you fast and the air gets thick, this cleaner can step up filtration to keep air quality high. 
Its HEPA Silent Technology allows it function effectively in the boardroom or your bedroom without adding to the noise level in your space.
Easy Maintenance
For the most comprehensive cleaning results, the filter should be replaced every 6 months.  The door on the side of the purifier opens for easy removal and replacement.  The optional Smokestop filter is available for an added layer of protection against smoke, odor, and volatile organic chemicals that can off-gas from paint, varnish, new carpet, and new furniture.

Gentle Stream of Clean Air
Its HEPA Silent filter technology eliminates pollutants both high efficiency particle arresting (HEPA) and electrostatic filters.  The surround air systems allows to it send air gently into the room rather than with a fast moving stream of air.  You will hardly know its on except that you notice an incredible difference in the way your air smells and how good you feel.
