This is a quality high air flow filter. I took static pressure measurements with and without these filters and adjusted my HVAC max air flow settings for each zone to stay within a 0.5 to 0.8 range for static pressure. I installed 3 of these filters and 4 months later they are still clean and having almost no impact on air flow. These filters are far better and flow significantly more air than really cheap 3M filters. They also fit the housing tighter and seal better. I know because I had some from previous owners to compare. I gave that junk away on marketplace. These combined with a robot vacuum and mop have kept my home virtually dust free over these 4 months and they have a lot of life left. If you think these restrict your air flow too much, you need to get your HVAC settings adjusted and possibly get professional help if your ducts aren’t sized properly. Air flow issues are a problem with your system, not with these high flow filters.

The best filters! Less dust and easy to change!!!

Feels like a well made filter, not flimsy.
