Designed for large rooms up to 20 by 20 feet, this air purifier changes the air up to seven times per hour and provides a CADR of 260 for smoke, 260 for dust, and 245 for pollen. Its effective three-speed whisper-quiet fan draws air into the unit without excessive noise, and exhausts clean, purified air back into the room from the top of the unit to avoid stirring up settled particles. The purifier also comes equipped with a True HEPA filter that effectively captures 99.97-percent of all airborne particles as small as 0.3 microns in size that pass through the filter. For 30-percent better odor reduction, its separate carbon prefilter reduces cooking, tobacco, and pet odors while also capturing larger dust particles, lint, and pet hair from dirty air.
The air purifier can be programmed to automatically adjust the fan speed up to four different times per day. Choose to have the same programs for every day of the week or choose different programs for the weekdays and the weekend. Other details include push-button controls, a power indicator light, a one-year suggested HEPA filter life, filter-change indicators, and a digital LCD screen that shows the time of day and cleaning level. Even more, the unit's space-saving slim-line styling fits flush against the wall, so it won't encroach on living areas or interfere with household activities. Replacement filters include a 30901 prefilter and a 30940 HEPA filter.
