Review on 🔍 LINNIW 2 Pack H13 True HEPA Replacement Filter for MA-40 Air Purifier - High-Efficiency 3-in-1 Filters with Activated Carbon by Adam Krueger

I do not recommend these filters. After installing them and running the new air filter, I noticed a strange smell in the room, similar to cat pee. The witch is weird because I don't have cats. When I located it, I was surprised that the smell came from the air purifier. I took out the filter and sniffed it, sure it was the filter. I put in the second new filter I had and got the same order. I took them out and paid a little more for the brand name and the smell was gone. The lesson learned some things you don't want to skimp on.
