Six Proven Air-Cleaning Technologies

1. True HEPA Filter for the most effective protection against dust & allergens, such as pollen, ragweed, mites and mold spores. HEPA filters are recommended by the Department of Homeland Security and the U.S. Centers of Disease Control.

2. Germicidal UV Lamp to destroy micro-organisms such as germs, viruses, bacteria and fungi (such as mold toxins). Recommended by the U.S. Centers of Disease Control and the Air Institute of Respiratory Education. Also disinfects the micro-organisms that are trapped in the HEPA filter, which is why the CDC recommends using a germicidal UV lamp and HEPA air filter together. The second UV lamp in the Multi-Tech XJ-3000D can be turned on when extra sanitization strength is needed.

3. Activated Carbon Filter for chemicals, gases odors and cigarette smoke. The most absorbent filter material known to man. Recommended by the Centers of Disease Control, the Dept. of Health and Human Services and the National Institute of Occupational Safety and Health.

4. 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. Found to be highly effective in multiple U.S. Dept. of Agriculture studies.

5. Programmable Sanitizer to neutralize powerful odors. Can be completely turned off when not needed. Includes High, Medium and Low settings for appropriate output according to need.

6. Anti-Bacterial Pre-Filter for larger particles, lengthening the life of the other filters. Pre-filters are recommended by the Dept. of Homeland Security.

Other Important Benefits:

Quiet Operation ensuring peace and quiet while running, even with its powerful fan.

Low Energy Usage ensuring low electricity costs, even if running the Multi-Tech continuously.

Low Replacement Costs. Just $25 to $50 per year for replacement filters and UV lamps.

Everything You Need in an Air Purifier

Proven Results.

Many air purifiers are claimed to be effective, but few on the market can provide proof that they are effective. The Multi-Tech air purifier has proven to be nearly 100% effective in clinical test results.

Most Effective Dust & Allergen Filter Available.

True HEPA filters (recommended by the Dept. of Homeland Security) are more effective than any other type of air filter at capturing dust, pollen, ragweed, dust mites, mold spores and other allergens. Furthermore, in a Journal of Hygiene study, negative ions were found to improve efficiency of filter units.

A Way to Kill Micro-Organisms.

Most air purifiers do not have a way to destroy germs, viruses and other micro-organisms. A germicidal UV lamp is the most effective way to meet this requirement. UV light air purification is recommended by the U.S. Centers of Disease Control (CDC). Multi-Tech's ionizer is also effective against micro-organisms. The U.S. Dept. of Agriculture studies show that releasing high doses of negative ions into the air can effectively reduce airborn bacteria. And negative ions are completely safe.

The Ability to Remove Chemicals, Fumes & Gases.

HEPA-only air purifiers cannot remove these prominent household pollutants from the air. An activated carbon filter is necessary for this job. According to Penn State Dept. of Aerobiology researchers, carbon filters serve to remove odors, volatile organic compounds (VOCs) and chemicals that other filters cannot.

A Way to Reduce Cigarette Smoke & other Odors.

Many air purifiers also do not have an answer for most minute types of particulate, either. The Multi-Tech has multiple technologies for these miniscule pollutants and impurities, including the activated carbon filter, ionizer and programmable sanitizer.

Seeks & Destroys Pollutants Across the Room.

An ionizer (i.e. negative ion air purification) is particularly well-suited for neutralizing airborne pollutants that do not pass through the filter. The Multi-Tech circulates trillions of negative ions with a powerful fan to maximize this ability. The U.S. Dept. of Agriculture found negative ion air purification (ionizers) to be 99% effective at removing airborne dust & particles.

Certified to Be Safe.

The Multi-Tech air purifier has been awarded ETL certification, proving that it is safe to use in your home or office. It has also been certified in the state of California, and passes the UL-867 safety standard.


Like most people, you are probably too busy to remember to clean your air purifier. Fortunately, the Multi-Tech does not require maintenance, so you can get on with your life, while still experiencing pure air.

How the air-cleaning technologies of the Multi-Tech work concert to neutralize the broad spectrum of common household pollutants.

Dirty air enters the the air inlet.

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.

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).

The programmable sanitizer can be turned completely off, or activated to help reduce or eliminate odors.

Two powerful & quiet fans create strong air movement (for increased air-cleaning performance), yet do not disturb your home or office with loud noise.

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.

The purified air, along with negative ions, are accelerated into the air.


 Technologies in Order of Position in the Air-Flow Stream

Anti-Bacterial Pre-Filter

The pre-filter is the first in line.

Preserves the life of other filters, so more pores can remain available in the activated carbon and HEPA air filters for the finer, harder-to-remove pollutants.

Helps to eliminate bacteria to help prevent them from reproducing and recirculating into the air.

Activated Carbon Air Filter

The activated carbon is next in line after the pre-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.

True HEPA Air Filter

After the air has moved past the pre-filter and carbon filter, removing larger particles, many bacteria, chemicals, odors, etc., it comes to the thick layer of HEPA filtration.

Removes 99.97% of particles (at .3 microns in size) that pass through the filter, as verified through strict testing procedures.

Largely considered the most effective type of air filter for solid particles, such as dust and other allergens, such as pollens, pet dander, mold spores, ragweed, dust mites, etc.

HEPA filters are recommended by the U.S. Department of Homeland Security.

Germicidal Ultraviolet Light

The UV lamp is positioned behind the HEPA air filter. The UV lamp destroys the micro-organisms (such as viruses and some bacteria) that cannot be captured by filters.

Destroys micro-organisms. UV light is scientifically proven to destroy viruses, germs, bacteria, fungi (including mold), etc.

Reduces illness & disease. UV light has been used for years by the medical field to sanitize rooms and equipment, and to prevent the spread of illness and disease.

Recommended by Centers for Disease Control (CDC) for its ability to destroy biological pollutants.

Sanitizes the HEPA Air Filter. This powerful UV lamp is positioned where it can effectively sanitize the Hepa air filter.


The sanitizer is completely programmable. If turned on, it ozonates the air as it passed through, along with the air in the room. It also provides added UV sanitization. This function can be turned off completely if not desired or needed.

Ozone Free Operation. By default, the ozone sanitizer is disabled. If activated, ozone output can be set to Low, Medium or High.

Powerful odor eliminator, which is a weakness of most other air purification methods.

Air Ionizer

The ionizer is located just inside the air outlet. It circulates air-cleaning negative ions into the air.

Effectively removes particulate from the air, such as bacteria, smoke, and allergens such as mold and dust mites.

Circulates ions throughout the room, in areas where the filter has little effect.

Increases the effectiveness of the HEPA by causing smaller particles to conglomerate into larger particles, according to Journal of Hygiene.

Government studies show negative ions to be effective at removing dust and micro-organisms from the air (U.S. Dept. of Agriculture).

Ozone Free. The ionizer does not produce ozone as a byproduct.
