The Multi-Tech II XJ-3000D is everything you need in an air purifier and uses six proven technologies to cover up to 600 square feet!

How it works

1. Pre-Filter

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

2. Activated Carbon Air Filter

  • Carbon filters remove odors, volatile organic compounds (VOCs) and chemicals that other filters cannot.

3. True HEPA Air Filter

  • Removes 99.97% of particles (at .3 microns in size) that pass through the filter, verified by strict testing procedures.
  • The most effective air filter for particle allergens such as dust, pollens, pet dander, mold spores, ragweed, dust mites, etc.
  • HEPA filters are recommended by the U.S. Department of Homeland Security.

4. Germicidal Ultraviolet Light

  • Destroys micro-organisms. UV light is scientifically proven to destroy viruses, germs, bacteria, fungi, and mold.
  • Recommended by Centers for Disease Control for its ability to destroy biological pollutants.
  • Sanitizes the HEPA Filter. This powerful UV lamp is positioned where it can effectively sanitize the Hepa air filter.

5. Sanitizer

  • Ozone free operation.
  • Powerful odor eliminator.

6. Air Ionizer

  • 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.
  • U.S. Department of Agriculture studies show negative ions to be effective at removing dust and micro-organisms from the air.
  • Columbia University researchers found negative ions to have relatively no side effects.
  • Ozone free.

What are the Benefits of the Multi-Tech II XJ-3000D?

  • Removes 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. 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. UV light can be deadly for dust mites.
  • Effective Against Bacteria
    The Hepa filter and anti-bacterial pre-filter are effective at capturing bacteria, which si then disinfected by the germicidal UV lamp. According to studies by the U.S. Dept. of Agriculture, ionizers/negative ions are extremely effective at reducing airborne bacteria.
  • Reduces Pollen and Allergens
    Hepa air filters are commonly recommended filter for allergens, and are generally considered the most effective filter for allergens. Ionizers/negative ions 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.
  • Obliterates Mold and Fungi
    Mold spores are effectively captured by the HEPA filter with the help of ionizers/negative ions. UV light is deadly against the microbiological toxins associated with mold, and ozone sanitization is effective against mildew smells. The ozone sanitizer can be completely turned off if not needed or desired.
  • Captures Cigarette Smoke
    The carbon filter absorbs smoke particles and the toxic chemicals associated with cigarette smoke. The programmable ozone sanitizer (which can be turned off), also helps to reduce or eliminate odors from cigarette smoke. The ionizer/negative ions also remove smoke particles from air.
  • Neutralizes Chemicals and VOCs (Volatile Organic Compounds)
    The carbon air filter is very effective at absorbing chemicals and gases. The ionizer also help to neutralize chemical fumes.
  • Reduces Germs and Viruses
    The UV light is deadly against micro-organisms such as germs/viruses, and highly effective at destroying them as they pass by the UV lamp. Negative ions have also been known to help to neutralize viruses.
  • Removes Odors
    Both the ozone sanitizer and activated carbon air filter are effective at eliminating or reducing strong odors. The ozone sanitizer output can be adjusted, or turn off completely if not needed or wanted.
  • Defends Against Carbon Monoxide
    Researchers at Brompton Hospital in London discovered a significant decrease of CO values was found with an ionizer activated.

We Asked Customers Why They Like the Multi-Tech II XJ-3000D Air Purifier

  • "The best air cleaner ever made! This is my fifth one. You may think why do I need five of them unless it breaks easily. Not at all! I had the xj 3000c first and then it was so good that I bought for two of my children who had allergy and they were in the dormitory at the time. And I kept giving it to my family members who needs this in their home. Now I bought XJ-3000 D. This one is much more quieter and powerful. Whenever we had a cooking order in the house we use it. In about an hour any strongest smells disappear with ozone. I like this so much that I cannot live without them." † ~ Soexci Ted
  • "Helps! I can tell a difference in the air - smells cleaner. I purchased 2 since I thought it was worth it. One for my teenager's room. It appears to help my allergies. No problems." † ~ E. Haught
  • "Wonderful for allergy sufferers! I suffer from horrible dust mite and cat allergies (I have 2 cats) and this purifier has made a world of difference. I no longer wake up with the stuffy nose and crusty eyes. It's a little loud, but not much louder than the air conditioning. I researched a lot of purifiers online and this one had great reviews for those I found around this price. Definitely worth the money. I've had it a few months now and I wouldn't sleep without it." † ~ ShastaLynne

Why is the Multi-Tech II XJ-3000D Air Purifier Different from the Others?

Still Not Sure a Multi-Tech II XJ-3000D Air Purifier Can Help You? Read These Reviews...

  • "Most sensible thing I've ever bought! started to run this air purifier exactly 52 hours ago, and it has already changed my quality of life. I have never owned an air purifier before. I have been literally choking on the air in my own apartment during the several months that I have been living here, and I had extremely unrealistic expectations about an air purifier: I imagined posting something like, "Wow! I could feel the difference after two hours!" Well, OK, it took more than two hours! But it happened." † ~ Marie-Claude
  • "The best purchase I have made in many years! I can't say enough about how good it works at removing smoke and tobacco odors in a fairly good size room. I've bought other so-called air cleaners and wound up putting them out for the trash. Not to mention the money I save on expensive room deodorant sprays (which never really work anyway as they only mask the smell for an hour or so). It feels good to come home and not smell cigarette smoke as soon as you walk in the door. Do not hesitate to buy it. It's worth every cent and more." † ~ sweet sue
  • "Smokers Heaven! I'm a heavy smoker,and can't stand the smell of smoke in my home. When company comes into my home, they swear it is free of the old smoke smell, that bothered me so before ... I would totally recommend this product to anyone who has stale or bother some odors, expecially a smoker in their homes, as this unit totally works!" † ~ camichel
