Can notice the improvement over my old ones

Excellent filter, works well

The only thing I could complain about is how big the box they came in was

I would recommend this brand to anyone looking to purchase a filter, and MERV 8 is all you need to buy unless your HVAC system was designed for a higher filter level

They fit my air handler and my intake air vents with no problems or issues

Hard to find size, great filter Works great meets need Still working my way through the first order
