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.

We for the lifetime warranted MaxMERV9 air filter. Customer service is kind and generous. We highly recommend NeverBuyAnotherFilter!
We have had the filters for only a short time but we have already noticed a significant difference on air quality in our home.
I have only had the filter in for a week now but it seems so far t be working fine. I will know more once I have taken it out and washed it to see how it performs. The delivery was quick and it arrived in perfect condition. I would have given it five stars except I haven't cleaned it yet, so I am not completely sure yet but all indications seem good.
Received damaged filter and customer service immediately put another in the mail. Couldn’t be more impressed! Also, love the filter. Wish had bought years ago
