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.

PEAK ARRESTANCE: 83.2%
INITIAL RESISTANCE: 0.252" WG
DUST HOLDING: 68 grams
AIRFLOW RATE: 295 FPM
END POINT OF TEST: 1.00" WG

One of the filters came popping out of the side enclosure. I tried popping it back in then it started bending - what a kinda sorta mess. I am not sure it is worth the hassle of Fedex and such. Thanks for listening!
Awesome filter, well constructed and the BEST part is, it stays in place. Love it!!!
These filters are as advertised. Works well and easy to clean. I now have three in my house and we are fairly dust-free.
It is well made and appears to be doing a great cleaning job.
The build quality is readily apparent when you unbox your filters. I order two to allow drying between cleanings. I havent washed them yet, but I will be doing so this coming weekend. I am a firm believer in eliminating unnecessary waste, disposable filters seems to be on that list. I expect to get many years of use out of these. I hope the filter material will last. So far, I'm very happy with my decision to buy these filters.
