The Honeywell 50150 offers efficient localized air purification in a quiet, efficient package. At 18-inch x 18-inch x 15.1-inch and 18 lb, this Honeywell air purifier is small enough to be placed at the corner of any room, yet powerful enough to purify up to 235 sq ft of living space. An activated carbon pre-filter removes odors and traps harmful vapors, while a HEPA air filter removes airborne particles down to 0.3 microns. A 360-degree air intake and discharge design offers fast and consistent purification, while three different cleaning power levels allow the user to tailor this Honeywell 50150's fan speed and filtration power to the needs of the particular environment. Unlike other products that require frequent filter changes, this Honeywell air purifier utilizes a permanent glass fiber. When indicated by the filter replacement indicator, this HEPA air filter can simply be vaccumed clean. The filtration system never loses effectiveness, ensuring that indoor air pollution such as dust mites, pet danger, mold spores, pollen, and smoke are continually removed from the environment. Homeowners looking for a high-efficiency filtration system will find the Honeywell 50150 a low-maintenance and economical choice for any room, large or small.
