How does this combination of filtration mechanisms work? To start with, the dust collection grid is electrostatically charged to capture airborne particles like a magnet. The HEPA filter captures allergens, dust and other airborne particles.

Gases, odors, and chemical smells are trapped by the activated carbon filter before they find their way into your nostrils. The Germicidal UV lamp of the XJ-3800 kills airborne disease causing microorganisms to ensure that your family is protected from flu, common colds, and other airborne illnesses.

The XJ-3800 uses smart sensors to monitor and display the conditions of your room. It utilizes dust, odor, and allergen sensors to let the user know the exact air pollutant detected in a room. Whether it detects chemicals, cigarette smoke, dust mites, pet dander, mold spores, or pollen, the XJ-3800 will let you know the pollutant in your room. You don’t have to guess.

In addition, its diagnostic sensors notify the user when to replace filters with new ones and when to clean the dust collector. Furthermore, the XJ-3800 uses sensors to ensure that electricity usage is minimized. However, from our research, we noted that this unit consumes more electricity than most air purifiers of same or higher capacity.

If you are looking for a quiet air purifier, the XJ-3800 offers the quiet setting to allow you to enjoy clean and fresh air in a noise-free environment. This setting offers nearly silent operation and it is suitable for places that demand quietness such as bedrooms.

Users' feedback

Users quotes on Amazon.comIt's bigger than it looks in the pictures: Stands about thigh-high. This put me off at first...but then I plugged it in. First impression: It's not doing anything. After two days: I want to have it's babies. I have allergies...miserable miserable allergies, and I just moved back to maryland during the worst allergy season I've seen in years. To a house with three smokers. And Two Dogs. And Two Cats. This house has clutter (re: dust) and mold and four plants in the livingroom and old carpets. It has old furniture and crummy filters but it DOES have ceiling fans! This house is allergy hell. and this purifier?...Ah...I swear I can breathe again. It cleans up the air (auto setting rocks!) of the entire 500 sq/ft first floor from *awful* to *clear* in roughly 20 minutes, and if it's running constantly, it never gets intolerable. In fact, it barely ever gets to worse than "do you smell something?" for more than a minute or two, even if there has been cooking and smoking and the dogs were in the rain. Even if it only lasted 6 months before it totally broke down, it would be worth the price to pay every six months to get another one. I am in love. Make more of these. Buy it. Buy ten and give them to your friends. Send this link to anyone with allergies. Or gas."

Users quotes on Amazon.comI've had two of them for 2-3 years now. I can say it's one of the best. It cleans well -- everything as far as I can tell -- and stays quiet except when it kicks into high, if there's a burst of dust (or odor I suppose). Filters are easy to clean, and reasonably priced for replacement. I have a top of the line Blueair for allergens. If I do serious experimentation with efficacy of various air cleaners, I'm afraid I'd die from allergy before finishing. So I can't attest to the efficacy of this unit in HEPA. I had, however, tried a bunch of low-end filters with supposed HEPA before and they did nothing."
