I want to get a washable, permanent air filter for our HVAC. I see two options for myself. One is a unit like this, same brand except different size (20x30) at my local Lowes, about $20-25. Nothing wrong with the price, but the company itself has a ramshackle website and I'm not sure if the material is even made in America or if it filters as well as it claims to (Merv 8 rating). My second option is to go with a K&N. I can get a 20x30 for $60 plus, and it is MERV 11, higher than the product I use now. If I do go with K&N, it is expensive, but even at that, I'll break even after 4-5 years, and then I'll make money, as well as eliminate the disposal of an air filter every 2-3 months. So if I have to go that route, I'd be ok. But I am wondering if there is anything in between these two, price wise?. I really don't need MERV 11. I'm fine with the current filters we are running, that are 600 MPR (=8 MERV).
