Kitchen and Housewares Reviews of Friedrich C-90B Electronic Air Purifier
Customer Review: Yes, it's that good
Summary: 5 Stars
This really is an outstanding air cleaner. It eliminates almost all my allergy symptoms. I've had mine for four years now, and it's as excellent as the day I bought it. I've run it 24/7 the entire time, and even put it on an A/V cart so I can easily move it from room to room occasionally.
I replaced the carbon filter once a couple years ago, but I really don't notice one way or the other on it. A room just doesn't smell any more if you let the cleaner run a while. Even when the carbon filter is depleted, the cleaner still makes a tremendous difference in a room's air.
Customer Review: Great Product, Owners Manual Missing Some Info
Summary: 5 Stars
I've had this product for a bit over a week and it works very well so far. The cleaning directions in the manual aren't nearly as good as they could be. The Honeywell manual for products which use the same air cleaner cell suggests placing several water glasses on your lower rack in order to support the air cell, rather than just dropping it onto the tines. It also says to not use the dry cycle, as it will bake the dirt into the cell.Customer Review: Very nice Unit
Summary: 5 Stars
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

Customer Review: Friedrich C-90A Air Purifier
Summary: 5 Stars
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.
Customer Review: Works well, minor quibbles -- first invest in well-sealed ducts
Summary: 4 Stars
Indeed this unit works much better than units by Honeywell and others I've used. It doesn't sound like a jet engine, like the Honeywell blasters. Importantly, the C-90 doesn't have coatings on its filters that can bother some sensitive people. Other brands do have those coatings. There isn't another filtration unit on the market that can touch the C-90's cleaning efficiency. Although the famous (and litigious) consumer magazine says that the C-90 produces less ozone than competitive products, I am able to smell the ozone when the unit functions, but not on competitive products. I called Friedrich about this, but the person they said would respond never called me.
The price of the C-90's carbon filter is downplayed, but it is far from free. The unit should have casters for easier movement, although it is not terribly heavy.
It's worth noting that this unit, designed to clean a small space, costs about the same as a good whole house filtration unit, which may be a better investment. The whole house cleaner is installed directly in the duct system, and is silent.
I just had my old ducts replaced and cleaned, which made a far bigger difference than running the C90 AND a whole house unit simultaneously. If you have a lot of dust, then you should consider updating your ductwork. Having done so, I no longer need to run the C-90.
Update: Consumer Reports, which previously rated this unit highly, now does not recommend it, or any other electrostatic cleaner, because of the ozone it generates.
