Q; Do the air purifier water filter types do a good job? I'm looking for an inexpensive way to treat my college dorm room. (Glen, Denver Colorado)
A: If you're looking to remove a little dirt and dust from the air (got allergies?) then it is better than nothing, yet not nearly as good as a small HEPA filter for dust. But for a small dorm room, and a small budget, it just might be the thing for your health. In this review I'll go into the pros/cons and brands to help you determine if a water air purifier filter is right for you.
Water works pretty well as a filter for dust, pollen, and dirt in the air and we would use the rainbow water vacuum as a way to quickly clean the air on occasion.
2 - No filters to replace
Con's 1 - Adds to humidity in the room
2 - May also increase mold/mildew
3 - Uses more energy. Primarily for small rooms as the amount of energy needed to draw air through water is greater than a HEPA filter.
1) Thermax Water air purifier water filter($56)I suggest you read the reviews on Amazon before you decide (click the link below) on this model. It says it covers 800 square feet but I'm not convinced of that until I try it. It's rather small, and a little louder than I like but the reviews were positive.
2) Sanyo ABC-VW24 Air Washer ($149.95) This is the only name-brand model I found and it has a full sized air purifier feel to it. 3) EcoGecko Pure H2O Water Based Mini Desktop Air Purifier ($24-30). A bit on the pricey side for a little ball of water with a fan. The disturbing thing for me was the way it is powered - by USB port. It's a cheaper way to manufacture it (no converter from 110 needed) but most geeks won't want to take up a USB port for this thing, let alone have something with water close to the computer.
So it's technically not an air purifier water filter but really a HEPA air purifier that uses electrolized water technology to purify the air.
You might be better off with a small $99 Air Purifier like the one below which has HEPA, UV, Tio2, washable Filters, Negative Ions and Carbon to do alot more and use less electricity.
