Winix Air Cleaner - Plasmawave 9000 Review and Test Results

Retail Price: $299.99

OVERVIEW: The Winix Air Cleaner, called the Plasmawave 9000, 9000s and 5000 (we'll be reviewing the 9000 here) are a line of multi-technology air purifiers sold in stores - especially Bed, Bath and Beyond. Nothing really new here in it's technology, so after we watch the video review we'll look closely at the quality, replacement filter cost and value of this brand.

5 Stages of Purification

5 Stages sounds good, right? I had to say 5 but my review of the Winix Air Cleaner shows that it's not just how many...

Stage 1 Anti-bacterial pre-filter. This pre-filter will keep germs and bacteria from developing on the pre-filter (not in the air of the room).

Stage 2 Hepa Filter - our primary pollen and dust collector recommended by Doctors. You'll be paying $100 every 6 months in the average home to replace this filter

Stage 3 Silver Mesh Shield - neutralizes bacteria on contact (good for the inside of the machine, but won't help bacteria in the room)

Stage 4 Carbon Filter - Washable (very thin). Carbon absorbs gas and odor, and while you can wash it on occasion any water inside of it can create otehr problems in the room. This units carbon filter is very thin, so I doubt it will work very well, or absorb much before becoming filled with gas.

Stage 5 Plasma Wave On/Off switch (Electronic Grid - neg/pos charged) - (combines with water vapour produces Hydroxyls - kills some viruses and odors). I talked to several Scientists about the hydroxyl approach to viruses and they didn't believe it was very effective.

Score: 48 = Fair


Given the price of the Winix 9000 Plasmawave and the replacement filter cost I don't believe it is a very good value. But my opinion is it is better than the Oreck and other infomercial brands. The square footage is small, the replacements filters are $100, and it's too loud (even with a brushless motor).

The factory they are made at - I'll just say they rank in the middle of the field for quality. If you have a Bed, Bath, and Beyond nearby and want the convenience of returning it (you can't get a full refund if you use it at all) or replacing the filters locally it might be an option.
