How the S3500 HEPA Air Purifier Works
The Top 6 Air Purification Technologies - In One Unit.

1. Pre Filter. The air first enters pre filter, capturing the largest particles, which enhances the durability and performance of the other filters.

2. High-Efficiency HEPA Filter. The most effective type of air filter at capturing dust, allergens and other solid particles (including bacteria). HEPA filters are recommended by the U.S. Department of Homeland Security. The S3500 uses a permanent, washable HEPA, so it does not require replacement.

3. Activated Carbon Filter. The best type of air filter for trapping chemicals, gases, odors and cigarette smoke. According to Penn State Dept. of Aerobiological researchers, carbon filters serve to remove odors, volatile organic compounds (VOCs) and chemicals that other filters cannot.

4. Photocatalytic Oxidation Filter. This filter is coated with titanium dioxide, which produces highly reactive ions and electrons when combined with the UV light from the S3500's UV lamp. These highly reactive ions attach to chemical molecules, bacteria and odor-causing compounds, destroying them through oxidation. Independent tests by research scientists have proven photocatalytic oxidation to by highly effective. How TiO2 UV Photocatalytic Oxidation Works

5. Germicidal UV Lamp. The most effective way to destroy micro-organisms, such as germs, viruses, fungi (such as mold) and bacteria. Also destroys micro-organisms including those that are trapped by the HEPA air filter, preventing them from reproducing and recirculating through the room. UV lamps are recommended by the U.S. Centers of Disease Control.

6. Safe and Effective Ionizer. Circulates trillions of negative ions to neutralize floating pollutants throughout the room. A Journal of Hygiene study found negative ions to improve efficiency of filter units, and multiple studies (including those by the U.S. Dept. of Agriculture) have found ionizers to be highly effective against dust, bacteria, etc. Finally, the S3500's ionizer is proven to be safe, producing virtually no ozone whatsoever.

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 highly powerful fan. Unlike most air purifiers in this class, the S3500 also includes multiple other technologies to address all the other pollutants that are typically found indoors.

This combination of technologies results in several unexpected benefits, such as:

Destruction of Micro-Organisms. Very few air purifiers address the problem of micro-organisms. Airborne germs and viruses are commonly present in indoor environments, circulating sickness among occupants. Other micro-organisms can increase the risk of sickness, such as mycotoxins from indoor mold growth. Furthermore, dust is often loaded with bacteria. The S3500 includes a jumbo germicidal UV lamp for a larger dead zone for micro-organisms such as germs, viruses, bacteria and fungi. In addition, this germicidal lamps sterilizes particles trapped in the filters, which can otherwise reproduce and recirculate with other air purifiers. The S3500's photocatalytic filter also helps to neutralize micro-organisms, such as bacteria.

Removal of Chemicals, Fumes and Gases. Most air purifiers are equipped with a way to trap dust particles and other allergens. However, very few are able to take care of chemical fumes that are common in households today. Chemicals fumes are emitted by building materials, paint, carpet, and several other sources. Chemicals are also added to the environment frequently through the use of household cleaners. Activated carbon filtration is the most effective filter available at trapping chemicals. The S3500 also includes a photocataytic filter to add to its effectiveness against chemicals. How TiO2 UV Photocatalytic Oxidation Works

Odor Reduction. This is another area that air purifier makers often neglect. Your common dust removal filters will not reduce odors, a common indoor air quality problem. Activated carbon filters and photoycatalysis filters are effective against odors, which may be chronic (cigarette smoke or mold) or just a temporary problem (cooking) in your home or workplace.

Cigarette Smoke. If you have a smoker in your house or place of work, you need multiple technologies to cover all the pollutants associated with cigarette smoke. An ionizer will help to remove the smoke particles themselves, while the activated carbon filter and photoycatalytic filter will address the chemical pollutants and odors.

Ionizer Benefits. Not all high-end air purifiers include a built-in ionizer, but it is becoming more and more common, due to the clear benefits they offer. In a Journal of Hygiene study, negative ions (produced by an ionizer) were found to improve efficiency of filter units. Ozone-free ionizers (such as that found in the Multi-Tech S3500) do not present any potentially negative side effects at all. Plus, negative ions can remove airborne pollutants where they are floating, without requiring they pass through the air purifier. The S3500's powerful fan effectively circulates these air-cleaning negative ions throughout the area. Effects of Negative Ions
