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.

The filter is awesome, but arrived punctured and bent by UPS. After sending pictures of the damaged filter and shipping label, another filter was promptly mailed out and I hope it arrives undamaged.
The filter appears sturdy. Being able to wash it will
Help keep wasted filters entering landfills

Seems to be great construction!!! Hope this is last filter we will buy!!! Resting it out now!!! Liked the instructions. Air flow and wash this way!!!
I use to have another washable for years. I decided to buy the month ones. I would get busy and forget to buy a new one. So I decided to get this one for that reason. So far so good. It fit perfect.
