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

Good quality and value. fast shipping

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.

These were supposed to come with the other part of the filter for the air purifier!! I even asked if thats all i needed and I was told yes!!! The box part that the black filter is supposed to go on you never said i needed that as well!!! Now I have these black filters but the box part is missing!!! Thats not right at all!!!

Easy to use, and has a uv light plus quiet.

These filters are thicker and much better quality than the one that came with the air purifier. Very happy with purchase!

I have owned three of these air purifiers for a number of years. Very easy to use quiet and do a great job. I have ordered this one for a friend who has severe asthma.

These are thicker than other filters I have bought before which is nice because it actually helps filter. Some filters I have bought are so small that they don’t really filter. These were definitely worth the price, especially since I won’t have to buy filters for awhile.

Purchased these multiple times already whenever I need to replace my filters. They seem to have gone up in price this last order, but so had everything else

It goes to my air purifier that I purchased from you but I have not installed these are extra

Easy to install and good to have on hand!!
