Breathe NaturallyUniversal Cut To Fit Carbon Activated Air Filter - Replacement Charcoal Filters - Pre Filter Carbon Sheet for Air Purifier, Vent Filters & More - Made in USA (Pack of 6, 16x48)

This brand is thick, opaque and doesn’t flake charcoal unlike the thin, transparent and fragile filter that came with my portable AC. The removal of odors is excellent and the quality should insure filtering NO2 and large particles pollution. The filter is easy to cut with a sharp box cutter or scissors. The material doesn’t pill when cut. It’s the correct 16” width and it is long enough for 6 pieces, making changing the filter economical. I like that it is made in MN. The resealable bag is great for storing.

Nice big sheet of filter, I needed different sizes and this does the job, it's a bit thick but it works, I don't know if measuring and cutting is not what you want to do then I wouldn't suggest this product.

I have these on top of my mini split units in my shop to filter the dust and odor before it gets to the unit's air filter. They are awesome!!

Very nice product

Seems to do the intended job. I wrap the filter in my air purifier. I vacuum it off weekly and it seems to work for about a 6 month. I've read that you can wash and reuse this type filter, but they really don't work once washed, because all the charcoal washes out.
