Friedrich C 90A Air Purifier Review and Test Results

WATCH THE FRIEDRICH C 90A Air Purifier VIDEO BELOW...

OVERVIEW: I start by reviewing the Friedrich C90B which came after the Friedrich C 90A Air Purifier. C90B - replaced the C90A but both are identical versions. I've had one of these for awhile and I call it the "HUMMER OF AIR PURIFIERS". It's big, it's like an industrial strength air purifier, and Consumer Reports has had it at the top of the list for most of it's reviews. When you think of it think of "Truman Cell On Steroids" because it uses lots and lots of washable plates. The technology is also called electrostatic and electronic, but it all means the same.

3 Stages Of Filtration

Stage 1 - a prefilter which is washable for dust

Stage 2 - A large ionizer (positive and negatively charged air) with many, many plates

Stage 3 - A very thin Carbon filter as the air leaves the machine. It must be changed periodically


Pro's & Con's

Pro's 1 - Large washable electrostatic plates

2 - Covers 500 sq. ft.

3 - Heavy Duty Design

Con's 1 - No UV to kill viruses, bacteria Mold, No Hepa to collect Mold spores, pollen, particulates.

2 - Produces Ozone .005 and .020 ppm - though well below the FDA Standards

3 - Manufacturer stopped making any Air Purifiers including the C90B in 2008 and the C90 in 2005

4 -Parts are still available. Air comes in the back, so can't place it too close to a wall

Conclusion

If you have a lot of dust or smoke then it might be of use, or you have a heavy duty application (warehouse, garage, etc.) where you can wash it out every day or so then it might be a fit. It's too big and ugly for a house, doesn't collect enough pollen (no Hepa), and won't kill germs and bacteria for my liking.
