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.

Good ship time, box and filter had a couple dings but nothing to affect fit and function. Quality of materials is good, and well thought out design. I’ve only had the two filters in place for 10 days so too soon for a review. Send me the review request again in a couple of months and we’ll get down to details. BTW I’m ordering one for my daughter tonight.
I’ve had this filter for a few months now. It is easy to clean, I blow the dust out carefully with an air compressor.
Filter media is loose in the frame and can pop out during handling of you’re not careful
I have the handyman coming back in three months to replace/clean the filter. I have not used or even opened your package as yet. I am 85 years old and lie alone so I depend on the local handyman to do anything. I will let you know when the filter can be installed. thank you!
I have only had the Never Buy Another Filter in my system now for 7-10 days but the air does smell MUCH fresher. The mold smell in my down stairs that was present much of the time is nearly gone and only shows up after the rain. I am very pleased with it so far.
