Six Proven Air-Cleaning Technologies:

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. (More Info)

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. (More Info)

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. (More Info)

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. (More Info)

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.

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.

Maintenance-Free.

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 it Works:

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.

(More Info)


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.

(More Info)


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.

(More Info)


Sanitizer

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.

Notes:

Hydrogen Sulfide Test. Each unit was tested in a sealed chamber (2 hours) for its ability to remove Hydrogen Sulfide (H2S), a very difficult-to-remove toxic gas. An air purifiers ability to remove H2S is very indicative of its ability to remove chemicals, odors and other toxic contaminates.

Particle Removal Test. Each unit was placed in a sealed, smoke-filled chamber for one hour and tested for the percentage removed.

About Hydrogen Sulfide. H2S is a strong gas created by stagnant sewage, and is one of the very worst, and most difficult-to-remove pollutants known to man. An air purifiers ability to remove H2S is a good indication of its ability to remove strong odors, odor-causing toxins and volatile organic chemicals (VOCs).

Aspergillus Mold Test.
The ability of the Multi-Tech to kill aspergillus mold was also tested. In one hour of time, the Multi-Tech successfully destroyed 100% of the aspergillus mold cultures. Aspergillus is one of the most toxic and allergenic types of indoor mold.

Just some of the many types of pollutants removed by the Multi-Tech XJ-3000D:


Dust/Dust Mites. The Hepa air filter in the Multi-Tech "D" is highly effective at capturing solid particles such as dust and dust mites. According to the Journal of Hygiene, ionizers help to increase the efficiency of filters by causing airborne particles to conglomerate, making them easier to capture in the filtration material. Plus, negative ions also cause airborne particles to precipitate out of the air you breathe, and have been found to be extremely effective at controlling dust without the presence of a filter, through studies conducted by the U.S. Dept. of Agriculture. UV light can be deadly for dust mites.


Bacteria. Much of the bacteria floating around in the air can be effectively captured by the Hepa air filter, while the germicidal UV lamp serves to disinfect the bacteria trapped by the Hepa filter. Plus, according to studies by the U.S. Dept. of Agriculture, negative ion-producing ionizers are extremely effective at reducing airborne bacteria.


Pollen and Other Allergens. Hepa air filters are the most commonly recommended filter for allergens, and are generally considered the most effective type against them. Negative ion-producing ionizers increase the efficiency of filters by causing airborne particles to conglomerate, making them easier to capture. Plus, negative ions also cause airborne particles to precipitate out of the air you breathe.


Mold/Fungi. Mold spores are effectively captured by Hepa air filters, especially with the help of negative ion-producing ionizers. UV light is deadly against the microbiological toxins associated with mold. A second, high-powered UV light, adds to the germicidal power of the Multi-Tech "D" when activated. The activated carbon filtration, along with the programmable sanitizer, are effective against mildew smells often emitted by household molds.


Cigarette Smoke. The carbon air filter in the Multi-Tech "D" absorbs smoke particles and the toxic chemicals associated with cigarette smoke. When activated, the programmable sanitizer helps to reduce or eliminate odors from cigarette smoke. The negative ions also remove smoke particles from air.


Chemicals and VOCs (Volatile Organic Compounds). The carbon air filter is very effective at absorbing chemicals and gases.


Germs/Viruses. The UV light is deadly against micro-organisms such as germs and viruses, and highly effective at destroying them as they pass by the UV lamp. Negative ions have also been known to help neutralize viruses.


Odors. Both the programmable sanitizer and activated carbon air filter are effective at eliminating or reducing strong odors.


Carbon Monoxide. A statistically significant decrease of CO values was found with an ionizer activated. This was discovered by researchers at Brompton Hospital in London, and published in European Respiratory Journal.
