Kitchen and Housewares Reviews of Friedrich C-90B Electronic Air Purifier
Customer Review: 5 stars for the product, 1 star for the manual
Summary: 5 Stars
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).
Description of Friedrich C-90B Electronic Air Purifier
Friedrich's C-90B electronic air purifier uses the same technology generally used in whole-house and commercial installations. This Friedrich Air Purifier is ideal for allergy sufferers because it is very effective in removing pollen, dust, mold spores, and other particulates from the airflow that trigger allergy symptoms. This filterless unit supports a thin carbon mat to absorb odors. This electronic unit works with two sets of plates. One set of plates charges the airflow and another collects any particles that were charged by the first set. This makes it a true electrostatic system. Since there is relatively little constriction of the airflow, the units tend to be quiet, producing only a quality white noise due to the operation of the fan.Allergy, Sinus & Asthma
