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.
This filter is 7/8 inch thick
PEAK ARRESTANCE: 83.2%
INITIAL RESISTANCE: 0.252" WG
DUST HOLDING: 68 grams
AIRFLOW RATE: 295 FPM
END POINT OF TEST: 1.00" WG

MaxMERV9 - The High Arrestance Washable, Permanent, Electrostatic A/C Furnace Filter
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.
Good design, well built. Get the most bang for the buck
Highly recommended! I am very pleased with this product. Very well made and fits in the existing filter slot like a glove. I anticipate years of no more filter buying with a better filtration rating as a bonus. The only suggestion I would make is adding a pull handle to one edge to make removal for cleaning easier. With a paper filter you can just collapse the filter to get a grip on it. You can't with these. So I added a small handle to one edge to make removal easier. No big deal. Great product!
