Clean fresh air...your good health and well-being depend on it. But according to the Environmental Protection Agency, today's tightly-sealed homes and offices can have air that is up to 100 times more polluted than outdoor air. An air cleaner is an excellent way to minimize indoor pollutants. The C-90B, Friedrich's second generation electronic air cleaner, effectively cleans the air for a healthier, more pleasant indoor environment. They've taken the best and made it even better. The C90 has been consistently top-rated by leading publications. It quickly eliminates dust, tobacco smoke, pollen, pet dander and other allergy and asthma triggers. The C90B's clean air delivery rates (CADR) are as much as 18% higher than its predecessor, the C90A, which already outperformed 99% of the AHAM certified air cleaners on the market. And, no other air cleaner rated for 600 sq. ft. or less, outperforms the new C90B. The C90B is ENERGY STAR qualified. It uses about the same amount of electricity as a household light bulb. Growing concerns about ionizers and indoor ozone levels have caused confusion about what is safe. In independent test, the C90 was selected as the best safe and effective choice, producing only minimal amounts of ozone. In standardized industry testing, the C90 produced only .014 parts per million of ozone, well below the UL and FDA limit of .050 ppm. And the Friedrich C90B has been proven effective by the Association of Home Appliance Manufacturers (AHAM). The C90B is quiet and unobtrusive. At times you may not even know it's running. On the low setting, it runs at 45.89 dBs, almost as quiet as a PC. This makes it ideal for bedrooms and offices, as well as for family rooms and other high-activity areas. You can keep the unit operating at peak efficiency by periodically washing the electronic cell. Simply lift out the cell and submerge it in a bathtub ot other suitable container. It may also be placed in an automatic dishwasher. The pre-filter can be rinsed with Average Rating of 4.00 out of 21 reviews

BEWARE OF HORRIFIC MESS!!! - V. Bramlett, Mar 03, 2008
I am a very careful shopper, and meticulously care for my property. This air cleaner was purchased on the recommendation of Consumer Reports.
The air cleaner would work well for awhile, but then I would notice BLACK FLECKS all over the walls, ceiling, windows, throughout the air cleaner ...... everywhere throughout the room!!!!!
This mess is caused by the replaceable "carbon filter" at the back of the air cleaner, and the mess DOES NOT clean up with soap and water - a heavy cleaning agent is required!!!!!
After the 4th mess throughout the family room, and numerous replacements of the "carbon filter" (one $24.00 filter lasting a whole 2 weeks before it spewed all over the walls and the air cleaner itself), I ordered a "pre-cleaning filter" to replace the "carbon filter", but the air cleaner no longer turned on. I believe too much BLACK GUNK from the carbon filter had ruined the air cleaner - and there is no way to take the air cleaner apart to clean the inside.
I made contact with the company for help with the problem. They merely guessed at what might have happened and offered no solutions.
After only 2 years this $500.00 air cleaner (not including the numerous replaceable "carbon filters") now rests in a land fill!!!

5 stars for the product, 1 star for the manual - Trevor Goodchild, Sep 24, 2007
I have owned this guy since it came out and am very happy with the product, but the manual could use some improvement.
Used properly you'll get years of trouble free, cheap and clean air. The chief concern with a unit of this type is ozone production. Ozone is *bad* for you. This unit is *the* best rated unit for ozone production and its ozone levels are very safe -- *IF* the unit is properly serviced.
What the manual doesn't tell you -- if you smell ozone you need to clean the element. You will need to clean the element a lot. If you cant/won't do that, this is not the air cleaner you are looking for.
The second problem with the manual is the cleaning directions are frankly harmful. The manual says to use dish detergent. The dish detergent will react with the aluminum and over a long enough time line turning the element black. This deposit will act like a dielectric (just like the dirt the element collects naturally) and the thing will spew out ozone. Once this had happened I could not get the element clean again and had to replace it.
I suggest you clean the element in your dishwasher, with *no* soap and no jet dry. Fill the soap bucket with pure white vinegar and do a light wash. It will come out sparkling clean and so far mine has not changed colors -- sometimes simple is better. Vinegar is a natural aluminum cleaner. Do *NOT* add cream of tartar or baking soda (this is a common aluminum cleaning recipe) -- this will get baked on to the element and it will *never* come off. Ask me how I found out? :-)
Lastly, the element is a very standard Honeywell element. You can purchase one for around $125 from online HVAC sites should yours become soiled or damaged (the part # is stamped on the side of the element).

Awesome Air Purifier - Mojo Risin, Jul 16, 2007
This is a wonderful air purifier. I did my research before buying and pulled the trigger about 2 months ago. I am so glad I did. I no longer have the allergy issues that I had in years past. My main focus was clean air without the costly filter replacements. That is what you get with the C-90B. I placed mine in the bedroom and run it whenever I sleep. I just cannot begin to tell you how much it has improved my life. I sleep better and my waking hours are better as well. I would highly recommend this product to anyone as I am very pleased. Thank you Friedrich for making such a great product!

Might want to cut larger filters - M. L. Morgan, Jul 10, 2007
Air cleaner works fine, but filters that came with machine are a little small. It is easy to cut furnace filters to fit the cases. I live with 4 dogs, and they shed dust elephants worth of hair daily, so cleaners are put to hard use.

Cleans great but poor quality control; the truth about "snapping" - Patrick D. Kelly, Jun 10, 2007
We've bought 4 of these for use throughout our home ahd have had to return half of them (50%) due to quality control problems and "snapping". This is ridiculous for a product of this high rating and price. We've been seemingly through the trenches with these, dealt with dealers AND the factory and here's the result of our research.
Now, here's the deal re "snapping". There is appropriate snapping and inappropriate snapping/rubbing noises. Like bug zappers, large dust and dirt particules drawn into the cleaner are ionized and charged, sticking to the metal filter elements and may create a sharp electrical, bug-zapper type snapping noise. We've noticed that and can discern it. This is good and we have no problem with it.
The other snapping noise we've had is the fan blades hitting the inner plastic appliance/fan housing, especially when run on high. This is NOT good and we've had repeated problems. Our current crop of 90-B we can run the one in the basement on High and its quiet. The living room one we can only run on Med; on High in a short time we hear this rubbing/snapping-type noise. Both sit on level hard floors.
I let one of these run a while snapping/rubbing and upon examination of the inner plastic fan housing (you can look when you clean the filters) noticed black skuff marks where the fan blades (black plastic...that can flex on higher rpms?) rubbed the bottom of the housing. Taking coarse sandpaper I rubbed the scuff area repeatedly, over time eventually removing enough excess plastic, and the fan stopped the rubbing/snapping.
I called another high volume allergy product retailer in the area and asked if they had any problems, the clerk responded "You mean like parts rubbing? Uh...no. Never! Never had any problems". Well, the disingenuous answer and tone told me this was something they had heard before. I described the problems and types of noises to the Factory and they suspected the fan may have gotten misalligned, hence rubbing, in shipping to the distributor...told me to return it immediately. My retailer in Delaware had a good return policy, I kept all papers and documentation and conversations and actions on our part, worked with us and we were eventually able to weed through poorly performing units and do Frederich's QC research for them.
In summary, an incredible air cleaner when it works like its supposed to that I'd love to rate high but recommend to purchase only after reviewing your vendor's return policy (definately NOT mail order!!!) ...and don't modify the unit like we did to fix the problem as it will likely void any warranty. BTW, we've also not noticed any odor problems or anything else.
