Easy to cut to size
Used these to create custom filters for a 3D printer and to replace the filters on several air purifiers. They’re easy to cut to size and can be layered for a thicker filter if needed. Completely eliminated the smell from the 3D printer.

Good for odors.
Activated charcoal filters. Good for helping to eliminate odors. Can be placed in front of A.C. input to help eliminate sudden ( cooking, forget to take out the trash etc. ) odors. They are embedded with activated charcoal DON’T wash. You’ll remove the charcoal.

Good quality
The thickness is perfect to fit in my air cleaner. Very easy to cut down to fit in mine. No weird smells either. Good value for your money. I will buy these when needed again.

Using it for a Litter Robot 4 Carbon Filter
I have a litter robot 4 and the replacement carbon filters are very expensive – $30 for six. I knew I could buy these sheets & cut enough to come out with quite a savings & sure enough I did. These sheets are a bit thinner albeit they are denser – Even if I end up doubling the filters I will still come out on quite the winning side. I haven’t cut them all out, but based on the ones that I have cut out, I have more than doubled the quantity if I had bought the brand name filters. Based on the ones I have ready to go, it will be a year before I will need to purchase filters again – and I have three cats and empty the drawer bags twice a week so maybe that will help someone project how my use compares to theirs.
