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.
