1. Dirty air enters the air inlet.
2. High-Efficiency Filtration: Particles & pollutants are trapped by the 3-layer filter. The anti-bacterial pre-filter (blue) destroys bacteria and traps the larger particles, lengthening the life of the other filters. The activated carbon filter (dark gray) is the best type of air filter for trapping chemicals, gases, odors and cigarette smoke. The True HEPA filter (white) is the most effective type of air filter at capturing dust/allergens.
3. Germicidal UV lamp (positioned behind the filters) is the most effective air purification method available for destroying micro-organisms such as germs, viruses, bacteria and fungi (including mold).
4. The programmable sanitizer can be turned completely off, or activated to help reduce or eliminate odors.
5. Two powerful & quiet fans create strong air movement (for increased air-cleaning performance), yet do not disturb your home or office with loud noise.
6. A safe and effective ionizer circulates trillions of negative ions to neutralize floating pollutants throughout the room. Ionizers also enhance filter performance. Plus, the Multi-Tech ionizer creates virtually no ozone whatsoever.
7. The purified air, along with negative ions, are accelerated into the air.
