The most affordable, efficient and quiet, 6-stage all in one Purifier I have seen or tested! Auto-Air mode automatically senses odors in the air, and adjusts the fan speed. On the lowest fan setting, you cannot even tell the machine is working, and when on high fan mode is on, it will not disturb your usual daily activities! I personally have 2 of these in my home. The 3 in one replacable filter is long lasting, since you can wash the pre-filter, and very affordable when you do want to replace it.


True, Cleanable HEPA Filter for the most effective protection against dust & allergens, such as pollen, ragweed, mites and mold spores. The Multi-Tech 8500 uses a Professional-Grade HEPA filter, which is made with ultra-fibrous and ultra-absorbent HEPA material, which is more effective than the typical True HEPA filter. It collects more and maintains a high level of effectiveness for a longer period of time. HEPA filters are recommended by the Department of Homeland Security and the U.S. Centers of Disease Control.


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.

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.

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.

Photocatalyst Oxidation Filter which effectively reduces chemicals, bacteria and odors. Found to be highly effective in tests commissioned by the U.S. Dept. of Energy.

Cleanable Pre-Filter for larger particles, prolonging the life and enhancing the performance of the other filters. Pre-filters are recommended by the Dept. of Homeland Security.
