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.

Received it and it fit perfectly. So excited to put it through its paces (it’s a little late in the season now). Very well built and should last for many years. Thanks for good work and good work done in the USA!
Looks great, fits great, works great.
Well built, quality filter that does not restrict air flow.
It’s a great filter. But the metal frame makes it larger than 1 in depth. I had a tighter fit than expected in a new house - that I wasn’t aware of. If 3/4 inch depth offered, would have gone with that
I was very please with my custom filter. It's of great quality. Also I had great customer service and I received it quickly. Fast shipping. Works as advertised.
