5.0 out of 5 stars Remarkably cleaner air, November 3, 2004

By	Timothy C (New York, New York) - See all my reviews

I bought this pricey air purifier because it received the highest rating in a Consumer Reports field test. It may be expensive to purchase, but it's worth it. This model works by drawing air through a series of filters using a powerful 3-speed fan. A prefilter removes large particles/hairs, then an ionization chamber clumps the smaller particles, allowing them to be easily removed by the final stage carbon filter. This combination seems particularly effectively at removing dust, cat dander, pollen, and other odors. It also greatly reduces the odor of cigarette smoke that wafts into my apartment from a chain-smoking neighbor downstairs. The filter also proved effective at removing the odor of cat urine/feces near a litterbox.

Like all air purifiers, the big downside of using one is the energy cost and the cost of replacing the filters. Surprisingly, this unit users much less electricity than cheaper models and costs less to maintain since the filters are washable. Only the carbon filter needs to be changed every 3-6 months since it slowly loses its ability to absorb odor.

The ionization produced by the unit leaves a slight but noticable ozone smell when the unit is running. This may be irritating to some, but it actually smells pleasant to my wife and I since we know that the unit is working. The smell disappears in an hour or less after the unit's been turned off, even if it's been left on for a night.

I would highly recommend this air purifier. Since an air purifier needs to run almost constantly while one is home if "fresh" air is also coming in through an A/C or fan, it's important to pay more attention to the maintenance/electricity costs than the initial sticker shock.

5.0 out of 5 stars Very nice Unit, July 20, 2005

By	G. Kline (Saint Anthony Minnesota) - See all my reviews (REAL NAME)

Owned this unit for 2 months and has been working Great! Easy to clean with or without a dishwasher. By far the best money can buy compared to other Ion cleaners. Some customers have complained about noise on TV screen from the unit, I have had none of that.

Update: 10/10/05 Recived portable TV (casio EV-4500) TV has moderate to high RF interference from 0 to 20 feet from C90A. as far as I can tell certain itams my be affected by unit.

Pros: very quiet on all speeds. Very easy to clean and filters are very cheep compared to other brands e.g. Oreck. Consumer reports top pick. Very low O-zone level output. Moves lots of air. light on top showing that Ion cells working correctly.

Cons: this unit is very Big and ugly about 30lbs

5.0 out of 5 stars Friedrich C-90A Air Purifier, July 4, 2005

By	T. Anderson - See all my reviews (REAL NAME)

Friedrich C-90A Air Purifier is a 3 stage air cleaner that operates mainly on electronic filtering of indoor air. Very high marks by noted product review magazine. In use for one month, reliable so far.
Prefilter removes large dust particles.
Electronic filter removes almost all other particles.
Final carbon filter is for odor control. It must be replaced (quarterly?) to control odors. But unit will remove all dust etc without the charcoal filter.
Clean electronic filter weekly with water. Dry completely before using again. No other maintenance.
