The MaxMERV9 is our newest filter design, using the latest polypropylene weave technology to achieve a MERV 9 rating. That is the highest MERV rating given to any permanent, washable filter on the market today. We did not cut corners in developing the MaxMERV9. It features a super strong and lightweight aluminum frame and corrugated grid with double rivets and extra drain holes. This filter has a slightly higher air resistance rating but still provides better airflow than most quality pleated disposable filters. Like all of our filters, it develops a natural electrostatic charge as air passes through the media layers. This static charge captures and holds onto dust particles until the filter is cleaned. Designed for residential use, the frame is durable enough to be used in commercial or industrial applications. If you are looking for a permanent, washable filter that will capture the most dust and trap the smallest particles, the MaxMERV9 is your choice.
This filter is 7/8 inch thick
PEAK ARRESTANCE: 83.2%
INITIAL RESISTANCE: 0.252" WG
DUST HOLDING: 68 grams
AIRFLOW RATE: 295 FPM
END POINT OF TEST: 1.00" WG

If you do the math for I have to buy 8 20" x 20" filters and 4 12x12 filters annually. At your regular box stores they cheapest ones are around 14-25 dollars a piece. These washable filters will pay for themselves in one year and never have to buy another filter again!
haven’t put in u but, will in about two weeks
You asking me to review a filter I have yet to receive. Please ask me after I’ve received and used the item. Thank you
This has yet to arrive. I would be willing to rate again once it arrives- looking forward to getting it!
Is there anyway I can exchange for a flexible one I got the solid frame in and I can’t get it out I’m afraid I’m going to bend it
