5.0 out of 5 stars A PRODUCT THAT WORKS., March 19, 2008

I was surprised and not happy when I first looked into air purifiers and found the one recommended most often --Blueair--used filters that cost about $50 and had to be replaced every 6 months. That was a few years ago. Since then, I have not begrudged one dime of what I have spent for replacement filters. I have pets that shed, I live in Manhattan on a street that has been worked on constantly, creating lots of airborne dirt, and my building was repointed a couple years ago, providing more of the same. And I have allergies.

But I sleep well every night and wake up without a stuffy nose. These filters work, and so does the purifier-- as well as the day I first turned it on. So far it has outlived both the clock radio and a tower fan.

5.0 out of 5 stars Minimial cost for an excellent job, March 23, 2008

Like the other reviewer, I was a bit taken back by the $50 price of a filter that is supposed to be replaced every 6 months. But I bought the BlueAir 402 anyway.

This is one of those products that truly works! No false hype, no bogus claims. Since I don't have pets, and nobody smokes in my home, I have found that I can get a year out of a filter without a problem. At the same time, I am impressed at how well this filter performs. The intake side of my 402 air purifier gets dusty - the filter does show a darkening over time - and the outlet screen of the purifier has *never* needed cleaned. That says a lot about the effectiveness of this filter.

There may be cheaper, and there are systems that use multiple pre-filters to extend the filter life, but there are no better. If you are considering a BlueAir 402 or other model, don't let the price of this filter turn you away. You ARE getting what you pay for.

5.0 out of 5 stars Best prices. Best filters. But write down the date you put it in., January 19, 2007

This review is from: Blueair 400 Replacement Particle Filter for Model 402 Air Purifiers (Kitchen)

If you use the Blueair 402 Air Purifier for your office or bedroom, it truly is best if you change the filters every six months. It helps to write the date of the installation of the filter on the side facing you when you open the door of the unit so you know exactly when you put it in.

We found the best prices for replacement filters on Amazon.com. In the marketplace, they range from $[..] to $[..] each. Often, if you buy two or more, you get a good price break. They don't go "bad", so the pricing can make a difference on a per unit cost if you stock up on them in volume.

It's also good to clean the back metal screen on the unit ever other month. Turn off the unit, and clean upwards with a damp sponge until all the accumulated dust and dirt is removed. Let the screen dry and then turn on the unit again.

We find the 402 a great filter that makes no noise and does the job well.
