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

I have two of the Pure Guardian AC4825 Purifiers and change the carbon filters in them about once every 3 months. This 4 pack is perfect and fits without any problems or cutting. The price is also a lot better than buying the Pure Guardian ones.

I like that it seems to catch so much. I didnt realize I was breathing all that stuff Even my furniture stays cleaner from dust an pet hair

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.

Easy to install and good to have on hand!!

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

Easy to replace

These carbon filters are half the thickness of original ones sent with the hepa filter 2 pack...not what I expected.

These are your basic charcoal filters. You do have to cut them to fit. I used them as a replacement for my air filter instead of the much more expensive ones. I change mine at least every few months. Not sure how long these will last, well see, but they are the same filters I used on my old Hepa filter and they did the job.

Work well. Easy to install.

These were cheaper than the other filters offered by other sellers. I cannot say how well they work in terms of the activated carbon absorbing anything but it helps to be able to replace the outer filters when they become dusty. I put them in a 1 gallon zip top bag once I got them to keep them fresh (prevent the carbon from absorbing as much as it would otherwise). On the downside, although the width was correct, the filters are not tall enough so I have to cut one of the others to fill the rest of the filter area.
