Ionic Air Purifier PM 100 helps to remove pollutants, allergens and germs from the air right down to the sub-micron level (less than 0.015 microns). The silent and filter-less unit is effective at removing airborne viruses, bacteria, mould spores, fumes, odours, cigarette smoke, dust, and pollen all without a fan or a filter. Unit floods the air with negative ions that help people feel better and stay alert.Silent & Unobtrusive: With no fan or moving parts the PM 100 circulates purified air silently and efficiently. In 20 seconds, the PM 100 can purify the smoky air in an enclosed glass cover. Features: Use advanced electronic ionic air movement technology, soundless design, no motor, silent, cost efficient, low power consumption only uses 3.4 watts Static electric dust collector captures airborne dust, pollen, mould, mites and allergen. Circulates trillions of air-cleaning negative ions, collects airborne pollutants on magnetically-charged cell Loniser dust collector, convenient to cl
