Carbon Activated Pre-Filter 4-pack for use with the Germ Guardian FLT4825 HEPA Filter, AC4800 Series, Filter B By Complete Filtration Services

Super easy to put in, works just like the one that came with the machine. very good value for the dollar.

I recently purchased a replacement HEPA filter for my GermGuardian and didnt 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.

Just what I needed

Works great in the air filtration unit but cannot be blown clean or washed. Must be replaced. So in the long run may be a little pricey

Very easy to use and they work great! Thank you

If you think this is a replacement for the one that comes with your air filter you are wrong. This is filter cloth but it looks as though someone free hand cut it with scissors including the wrong angles and thin pieces hanging on the side from bad cuts. they also do not have the Velcro boarder that sticks it in place. does it get the job done yes. Other side is look how much you are paying for it because thats what you would be getting for that price. Works, ill probably buy it again but dont expect perfection.

Fits as intended but feels a bit different than the stock one and doesn’t stick as well to the Velcro on the machine but works well

Filter for Guardian Air Purifier

Product arrived day before expected delivery. These prefilters are for my Germ Guardian Air filter. They are a tiny bit bigger and a little thicker but fit fine. Very happy with them.

Product is good and performs well but gets folded up and sent in a bag, leaving the filters crumpled and creased and difficult to make them stay in place and fitwell on the larger filter. I set mine underneath a book for several weeks to get it to flatten out. There really should be another velcro spot halfway down the filter to hold it more securely. Otherwise the product works quite well.
