Universal 10x48 Cut-to-Fit Activated Carbon Filter (4 Pack) Charcoal Air Filter Sheet for Air Purifiers

I bought the 24" x 24". They are about 2 mm thick (0.07" thick - not 0.2" as advertised). Not at all sufficient for what is needed. Flimsy. Super disappointed.

The product is ok, I guess. I haven't really used it. I just received it after waiting 38 days. The company proudly boasts that this product is made in the USA. Company is in Minnesota. I went directly to the company website and started a chat communication asking about the month and a half shipping time estimate, and never received a response. I used the chat feature during normal business hours. It appears no one's home. No one making product, shipping product, or responding to consumers.

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.

Great value and not flimsy

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.
