MaxMERV9 (1 INCH THICK) - The High Arrestance Washable, Permanent, Electrostatic A/C Furnace Filter

Great Product so Far

Fit perfectly because actually checked. Saw some previous reviews and was puzzled by the feedback. Filters are a standard size/

OK, I bought one for upstairs in 2021 and I LOVE IT. I take it outside and use an air electric pump and you should see what got out in the atmosphere. It will blow your mind and not go in your LUNGS. Finally, I bought one for downstairs and it is just great, also. Yes, you initially have to put out money for a great filter BUT it is WORTH EVERY PENNY YOU PAY!!!

A better filter?

I replaced my 25 year old filter with this new one. They appear similar but this new filter is not as heavy or of the same quality of my older filters. I’m sure they’ll work, but may not be as durable. I love the concept of these filters, and the reusable nature of them.
