Good value, work for GermGuardian tower, and can be used for other appliances/applications
September 24, 2016
I recently purchased a replacement HEPA filter for my GermGuardian and didn't realize that it also came with a carbon activated pre-filter, so I also ordered this 4 pack. The quality is the same as the one that came with the GermGuardian branded HEPA filter, although the sizing was a bit different. I do not think I would have a problem fitting this into the GermGuardian, but they are also easily altered simply by cutting them with a scissors.
As I had 4 more carbon filters than I needed for a while, I used two of them for another separate air conditioner; I cut the filters to fit and inserted them behind the mesh filter in front of the rear air intake, effectively adding an additional filter where there was none from the factory. As the air conditioner runs 24/7 in the summer, I now had the added benefit of extra air/odor filtration, and the room smelled noticeably crisper.
These filters will work for your GermGuardian and are a good value, but be aware they can also be reconfigured for other applications where you might need a carbon filter. I even saw a picture on a website of someone who had attached them to the rear of an oscillating fan to help with filtration! Excellent for multipurpose use.
