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

Pleased

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.

I honestly didnt even know what these were when I got them. Now I know they make my filter last 4x longer. Nothing touched the filter with these pre-filters properly installed and changed regularly.

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

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.

Work well. Easy to install.

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.

Works fine but needs to be changed frequently. Like once a month maybe. Otherwise its gets blocked and the noise level increases

These came in a plastic bag with holes punched in it. Carbon filters degrade when exposed to air. All the other brands I have purchased come sealed in plastic for storage until opened. I dont think Ill purchase this brand again, because there is no indicator that the filters are fresh when they arrive.

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!!!
