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

I like the way that it captures all the dust in the air. Works well with my Germ Guardian air filter. I dont notice the air being fresher though. With the way the carbon should work. Overall happy with this filter cartridge. Would buy again.

Great by nice and thick great deal! Will buy again.

This toilet bowl cleaner is the bomb. It makes it much easier for me to clean the toilet. It has enough cleaner that I can clean 2 toilets with one wand.

These organic vapor filters work pretty well. I have the air purifier in the basement apartment. The dog comes down here and sleeps on the couch and her farts (shes a fat black labrador) are devastating, but these filters quickly filter out her stinkbombs.

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.

Changing this pre-filter on a regular basis will extend the life of the hepa filter. Also, keeps the air cleaner. Well worth the modest cost.

The HEPA filters can be expensive and this little layer not only removes any odors from the air but acts as a prefilter for dust. This is a multi pack and you simply peal off the old one (best done outside) and then stick the new one on using the velcro strips.

I just changed my pre-filter after 3-4 months of use. I changed it based on time rather than a change in machine operation. It was extremely dirty; it looks like it did its job well. It protected the more expensive HEPA filter. Will buy more when needed.

They fot a little snug but definitely work.
