Multi-Tech S4000

Most Effective Air Purifier Multi-Tech S4000:

High CADR (Clean Air Delivery Rate) rating for dust particle removal.

Multiple technologies to remove nearly all pollutant types, including chemicals, odors & micro-organisms (6 proven technologies).

Very powerful fan (175 cfm) for high efficiency and large coverage area.

Very quiet, affordable replacement filters.

Effectively Removes: dust, allergens, mold, micro-organisms, cigarette smoke, odors, chemicals, bacteria and much more, thanks to the combination of several air-cleaning technologies.

Outperforms more than 80% of all air purifier models tested by AHAM, yet also includes additional technologies that for other pollutant types that are not factored in by the CADR testing method. This includes activated carbon filtration for chemicals and odors, germicidal UV lamp for micro-organisms, and photocatalytic oxidation filter for chemicals and bacteria.

Air-Cleaning Technologies

Six Proven Air-Cleaning Technologies:

  • True HEPA Filter for the most effective protection against dust & allergens. Recommended by Department of Homeland Security and U.S. Centers of Disease Control.
  • Two Germicidal UV Lamps to more effectively destroy micro-organisms such as germs, viruses, bacteria and fungi (such as mold toxins). Recommended by U.S. Centers of Disease Control.
  • Activated Carbon Filter for chemicals, gases odors and cigarette smoke. The most absorbent filter material known to man.
  • Ionizer which disperses negative ions to seek out and remove particles & bacteria from the air. Proven by government studies to be effective, and to enhance performance of filters.
  • Photocatalyst Oxidation Filter which effectively reduces chemicals, bacteria and odors.
  • Anti-Bacterial Pre-Filter for larger particles, lengthening the life of the other filters.

Other Important Benefits:

  • Large Coverage Area as a result of the extremely powerful fan. Covers up to 800 square feet.
  • 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 S4000. Includes Ultra-Quiet fan setting for optimal energy savings.
  • Low Replacement Costs even when considering there are 6 purification stages.
  • Advanced Controls to suit your specific needs. Includes timer and independent Ion/UV control.

Excellent Dust Removal and Much More

Excellent Dust Removal and Much More

Like many expensive air purifiers, the Multi-Tech S4000 is highly efficient at removing dust particles, as proven by its CADR of 245. Unlike most air purifiers in this class, the S4000 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 S4000 includes two germicidal UV lamps for a larger dead zone for micro-organisms such as germs, viruses, bacteria and fungi. In addition, these germicidal lamps sterilize particles trapped in the filters, which can otherwise reproduce and recirculate with other air purifiers. The S4000'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 S4000 also includes a photocataytic filter to add to its effectiveness against chemicals.

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 S4000) 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 S4000's powerful fan effectively circulates these air-cleaning negative ions throughout the area.
