How It Works Gov't Studies Pollutants Specs Six Proven Air-Cleaning Technologies: True, Permanent HEPA Filter for the most effective protection against dust & allergens. Recommended by Department of Homeland Security and U.S. Centers of Disease Control. The most absorbent filter material known to man. Ionizer which disperses negative ions to seek out and remove particles & bacteria from the air. Photocatalyst Oxidation Filter which effectively reduces chemicals, bacteria and odors. Extremely Quiet Operation ensuring peace and quiet while running, even with its powerful fan. Includes "Ultra-Quiet" fan setting for virtually silent operation. Low Energy Usage despite the mighty power of the Multi-Tech S3500 (Just 85W power usage on high!). Includes the quiet "Low" fan setting for optimal energy savings. Also Features: Excellent Dust Removal and Much More. Like many expensive air purifiers, the Multi-Tech S3500 is highly efficient at removing dust particles, as a result of its 99% effective HEPA filter, and highl

Features:• Compact and Portable Size• Up to four stages of air filtration• Low electrical use, low maintenance• Quiet Operation• Variable Speed Controller for ozonator function• With high quality solid wooden box.• Stainless steel construction• No chemicals/ no residual contamination.• Energy saving, only consumes 20 watt power. • Coverage area: 3500sq ft.Comes With A 3 YEAR WARRANTY!Specifications:11.3 TRILLION ions generated per second 110V AC/60Hz 12-15 kv power supply , 43W 120 cfm 12 volt DC variable speed fan Height: 12.5 "; Width: 8.25"; Length 9.10" Weight 18 lbs The 300a is a two stage air purifier with a negative ion generator and a dual-ceramic ozone plate filter. The 300a's ozone function can oxidize the particles in the air and eliminate indoor contaminates. By significantly reducing various particulates in the air such as smoke, bacteria, dust, and allergens the 300a can greatly reduce the irritation of these con

This air ionizer removes particles as small as .01 Microns. Our Air negative ionizer emits no detectable ozone so don't expect the ozone smell that ozone generators create. The Wein Vortex Negative ionizer is a true high density negative air ionizer.n one hour, the VI-2500 will remove over 98% of the most respirable particles from the air in a very large room. These are the germs or pollutant particles that can lodge deep in the lungs that the body cannot exhale. The results are ten times better than the competitive widely sold unit. A sealed safety room would continue to be almost particle free as long as the unit runs continuously.Ion output:450 trillion ions/sec cm2 at 2.5cm, Coverage:800 sq. ft. (40' x 20') room, Purified airflow output: greater than 100 feet/minute.Negative Ions are molecules that have gained an extral electron. These are beneficial to the environment because they help attract dust, cigarette smoke, pet dander, pollen, mold spores, viruses, and bacteria; thus, helping eliminate them from the air you breathe. Have you ever noticed how fresh air smells after a rainfall or near a waterfall? If so, then you have experienced ionization in its grandest form.
