Friedrich C90A

Pros: Just about everything.

Cons: Noise, must be cleaned every week, expensive

The Bottom Line: The best mid-sized air cleaner hands down. If you are in need of one, you owe it to yourself to check this model out.

Review: I have to say that I am stunned that there has only been one review (prior to mine) on this product. The Friedrich C-90A air cleaner has been around for years and has been consistently rated as #1 by just about every consumer magazine out there. And ...

Pros: Fantastic unit, does the job very well.

Cons: Ugly, noisy on high, chore to clean all parts.

The Bottom Line: A must have for dust, pet, allergy, or odor problems in your house. You won't be sorry.

Review: I've run two C-90A purifiers in my house for more than two years now. There are a few downsides that you should watch for but I do recommend them. I bought them because we live in an incredibly dusty area and that was becoming intolerable. First, I ...

Pros: Good filtering; low maintenance costs; solid.

Cons: The fan hum bothers my wife (not me).

Review: Rather than most air filters which use disposable (and expensive) HEPA filter units, this Friedrich uses an electrostatic filter element to collect and trap dust particles. This is far superior to the electrostatic filters sold by Sharper Image because t ...

Pros: IT WORKS--unlike the Sharper Image ones. It works, it works.

Cons: None. We're delighted.

Review: My GF and I are both allergic to our cat, dog, dust, feathers... and of course we have some of each. We're used to waking up groggy and sneezy. No more. It really is a life-changer. Consumer Reports - gotta' love em - they raved about this being THE ...

Pros: Very effective. Cheap to operate. $15 a year for carbon filters.

Cons: Expensive. Other electrostatic precipitator air cleaners are cheaper. They may need carbon filtration added on.

The Bottom Line: Excellent electrostatic precipitator air cleaner. At low fan setting it is quiet and very effective. Only costs around $15 a year for bulk carbon filter material.

Review: I have had a Friedrich air cleaner for years. Here are some tips. Electrostatic precipitators (EP) produce ozone. Fresh carbon filter material catches it before it leaves the air cleaner. Consumer Reports reported no ozone from a Friedrich air cleaner ...

Pros: Very effective

Cons: Expensive , a little big & also boxy.Could have been a little sleeker looking

The Bottom Line: It is a little pricey at first , But seems to really work well

Review: I have only had this Purifier for 2 weeks so I can not give too much advice on it. I was in the market for an air purifier (cleaner) and like most people I was intrigued by the sharper image ionic breeze thingy (with the gp). After much research I ...

Pros: very effective, will quickly clean a room

Cons: large, little noisy, filter must be cleaned in dishwasher

Review: This is a powerful air cleaner that does a very good job at cleaning the air. My parents bought 2 after consumer reports rated it the best air cleaner. They have lots of dogs and cats, and I have allergies, and it significantly reduced my allergies when ...

Pros: Quiet, moves lots of air, seems to do a great job cleaning the air.

Cons: Frequent cleaning, Causes TV interference

Review: I've had this unit about three weeks. It move a lot of air even on low and medium speeds and is quiet compared to most other units that move large amounts of air. It seems to do a great job cleaning the room. The collection plates do need to be ...

Pros: Effective, quiet and works well on Medium and low settings. Filter cleans easily.

Cons: Could use wheels, makes occasional popping noise, Ozone smell apparent when cleaning a Musty room.

Review: This is our first Air Purifier and I have been amazed at how effectively it has helped the constant congestion and allergies my wife and I have suffered. We rent an Old San Francisco Victorian. The carpets are old and we have a dog. That combined with ...

Pros: When they work they are great.

Cons: Customer service is useless and dismissive.

The Bottom Line: If you are willing to take a chance with a $500 purchase, go ahead, most people like them. But don't expect any help from the company if you have problems.

Review: I purchased two of these units a year ago - an investment of $1,000. I used them over the last winter, and was very happy with them. Of the four people in the house, nobody noticed an ozone problem. I did not use them over the summer, but did clean ...
