PureZone Elite HEPA air purifier safely cleans the air in your home making it more breathable, enjoyable, and healthier. In 60 minutes it purifies the air in large rooms that measure 990 sq ft, or just 12.5 minutes in small rooms of 205 sq ft. The modern design complements any decor and features a sleep mode for clean air while you and your family sleep, 3-speed settings, and an automatic 2-, 4-, or 8-hour timer to conserve energy and extend the life of the air filters. Plug it in and notice that the quiet 36-decibel operation and energy star rating contribute to a tranquil atmosphere while helping to protect the environment. The filter reset indicator lets you know when it's time to change the active carbon pre-filter and H13 true HEPA filter. Using a 4-stage purification process - which helps eliminate 99.97% of particles as small as 0.3 microns - PureZone Elite air purifier provides a perfect solution for making the air more comfortable for people who suffer from allergies, asthma, or other breathing issues.
