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

Filter for Guardian Air Purifier

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.

I am extremely allergic to dust and these catch a lot of dust in my air purifier. I ought these because after I rinsed out the first one that came with the filter, I really did not want to put it back on.

Exactly what they advertised.

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

Pleased

Well if you have to buy filters then this is a good brand. I dont know much about filters however i have used this brand numerous times with no issues. Of course in hindsight i wish i bought a filterless air purifier but in the meantime i will continue to use this product. Yes i will recommend.

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.

This is the best value for the pre-filters Ive found.

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.
