Friedrich C-90B Review

If you're looking for a top quality electrostatic air cleaner and purifier that is unmatched and outstanding when it comes to removing removing airborne particles and elements, then the Friedrich C90B is yours for the taking! Now I know some users of the Friedrich C90B may have quibbles with this electrostatic air purifier when it comes to the maintenance and cleaning department. After all, its plate filters take quite a while to clean...AND you should clean it on a regular bases.

Coming as an upgraded version of the C90A, the Friedrich C90B comes with an enhanced clean air delivery rate (this is known as CADR for short). Not to mention it provides wider and better coverage for larger room sizes. Here's the bottom line - when compared to its predecessor (C90A which was well loved by the industry and especially those who used it) this air purifier is 15 percent more powerful and efficient!

Let's take a look at its CADR in a closer and more detailed fashion - it an remove 384 types of dust, 326 tobacco smoke, 421 pollen, and combine that with a 506 square feet coverage, the Friedrich C90B is an air purifier that can rival even the more expensive and more popular brands out there like the BlueAir 501 air purifiers that can remove 377 dust, 388 smoke, and 378 pollen.

The C90 purifiers, especially the Friedrich C90B, have a huge following, and it's not really surprising why. There are a couple of points or rooms for improvement, though, that I would like to bring to your attention. First and foremost, in high particle rooms, say bars and clubs where tobacco smoke is present and in high quantities, the electrostatic cell's efficiency will degrade very rapidly. With that in mind, you should wash the plates very frequently.

If washing is taken for granted, which is very common among air purifier owners, the electrostatic purifier will bypass many of the finer particles...it will leak just like any cheap HEPA air filter would. Not the most pleasant news in my book! Overall, however, I'm highly recommending the Friedrich C90B to anyone. Just remember, you need to maintain it on a consistent basis.
