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.

Perfect fit, fast delivery and even a follow up from this company. For us, it was money well spent. Thanks
I've had a set of washable filters for about a year, and am quite pleased with them and not having to buy and dispose of paper filters every two months. the only problem was getting them dry before reinstalling them, particularly in cold weather when we wanted the furnace on. I just bought a second set - problem solved!
Only have had my custom filter for two weeks but it fit like a glove and is working as listed.
This filter works great. It's easy to clean. There's more air flow and sure beats paying $10/month!
Ordered a filter, came in damaged. Reached out to CustomerCare and they were willing to offer me a discount. I tried putting up the filter and noticed that the filter didn’t fit. The filter was bigger than I expected. Reached out to CustomerCare and explained the situation and they sent me a new filter with the right measurements. Great customer service!
