The filters last a long time. As a matter of fact, when the one filter got dirty and needed changing, I just cleaned it off and re used it. I will definitely use a new one next time, though

Air is fresh in bedroom

Got this to replace our old filter. Fits and works well!

Nothing

If you need this replacement for your product that uses this, then this will work great. Have no complaints easy to replace the old one. Amazon prices this competitively with other retailers.

I have small apt and run in about 12 hours a day/night. It collects a lot of dust that I did not see on my tables. I change it more often than six months and I sweep filter every two weeks.

It takes out a lot of the dusty air we have in Yuma. Maybe not all of it but sure enough there is plenty in the filter. Thinking about having one in the bedroom too. Not real quite but its doing its job so..

This GENUINE Replacement filter for GermGuardian Air Purifier Models

It works great !

This is the third filter Ive used for my air purifier and They usually last a long time. I usually go 7-8 months before the purifier tells me it needs to be changed. The replacement times might be different for each house since dust levels might be different. I live in a very old dust prone house. They do a great job and every so often I vacuum off the dust thats accumulated on the back of the filter just to help make it last longer.
