Breathe Naturally Universal 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 1, 16x48)

Trying to control the musty odor from the crawl space until we can FIX the problem. This is working very well. It is easy to cut to fit the vents. It has helped more than I thought. Dust is less of a problem. For the price it has been worth the effort.

Great for covering vent covers to filter out mold spores, coupled with magnetic covers really help lower odours from vents. Nicely made.

I have been using these filters for years. The last three orders the manufacturer has made them thicker ....I love this new version ! Really have noticed better smell and lasting longer. Oh with some scissor work I can make 2 changes as a pre filter for a 24" x 30 air intake..

Fit with minor trimming in my health mate are cleaner. We have four dogs (one is a puppy and still not housebroken), and this has done a noticeable job in cutting down on odor.

Good product good price

Works great for fridge filters, ROI was exactly one expensive filter replacement and now I have enough for 4 years of filters... replacing these twice as often keeps everything smelling pretty fresh.

I needed these because we live in a downstairs apartment and share vents with cigarette smokers. If you don’t smoke then you know how bad it can smell and they start smoking at 5am. I took the vents down and cut the filter to size and just put them back up. There’s plenty left to change them out in 3 months.Results: they kinda work. I still smell the awful cigarettes through the vents but it’s not as powerful as it is without them . There’s plenty of air flow out of the filter but I’m slightly disappointed there is still a smell.

So far so good works great to hide dabsmell
