SUIXINEYI MERV 11 HVAC 16x20x1 Furnace Air Filter Pleated Air Filtersfor Home Air Conditioner,6 Packs

I have some chronic health issues and my medical team recommend better AC filters, and a standalone air filter, which I review elsewhere. I took a crash course on air filters. I do not pretend to be any kind of expert, and there are a lot of variables. What I learned for my purpose is that there is a point of diminishing returns regarding filter material and quality. I needed a Minimum Efficiency Reporting Values (MERV) of 10 . You can research the details behind MERV values online- there's tons, knock yourself our. Dr. Google summed it up best- "Sweet Spot: Most residential homes do best with a MERV 8 to MERV 11 filter." Higher MERV values sound like a good deal but can overstress older HVACs. Filters are made of all kinds of material, including reusable filters. Again there is lots of info online regarding types- all of which I flushed from my brain as soon as I made the decision to buy these. I am not in a position to be responsible enough to use the more environmental friendly filters as they require more work. I hope to do so in the future, but for my needs this seems to be a great choice. Instillation is straightforward, just like other filters I've used. Put the arrows in the right direction (do read first) and slide it in. This filter seems to be more substantial than some of the cheaper filters that I've had to use at times. This is $35 for a set of 6, and the recommendation is to replace at least every 2 months, up to 3. So the filters cost about $35 per year to use. That seems to be quite reasonable.
