Carbon powder on filter matrix

I used some of this on my mini-split indoor head units to reduce odors in the room. It does not have to fit snugly to do the job as long as some air passes through it. Also can use these sheets to cut a replacement carbon filter for my vertical cylinder type HEPA air filter. Helps with cooking odors. It does not shed any black particles unless you really agitate it.

Just what I needed

Exactly as expected. Easy to cut to any size. Nice surprise - a little thicker than I thought they would be. Great for using in/on soooo many things.

good quality carbon filter. can be cut to size

these carbon filters are just a little bit thicker than the ones that came with my air purifier. they work so much better than what came with the machine. they're perfect for keeping dust and smoke particles out of your air. you need these if you have an air purifier because it makes that expensive filter last longer. good quality long lasting. I would recommend these to anyone that needs them. these were not the exact size as my machine but I was able to cut them to fit. because they Velcro on
