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

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.

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.

Easy to install and came on time. You get exactly what you pay for and it’s good quality. This is the second time I have bought this product and will be buying again in the future. Would definitely recommend.

Works well in cleaning the air in a small room if you have pets

Easy to attach. I am able to vacuum it clean and only have to change it every third month. I vacuume it the month after changing. Easy to do but I did put tape on edges to make it last one more month before changing. These pre filters are inexpensive and worth it.

PRO: Can extend the life of your primary HEPA filter CON: (Not really a con, just an observation): Unless you put yourself on a schedule to replace this PRE-FILTER to extend the life on your HEPA PRIMARY filter, youre probably better off getting the combined product which allows for quick, clean, reliable replacement of BOTH filters at once.

I bought this to go with the filter that it lists in the title but I had to cut it to fit the filter. Not completely compatible

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.

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 filters were folded into half. There is no way to smooth the folded winkles.
