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.
Yes. Our permanent filters are available in standard and custom sizes. We offer 12 different filter types to fit most needs.

Some early permanent filters were very restrictive and gave the product a bad reputation in some cases. Some HVAC contractors still tell their customers that all permanent filters are bad.
However, not all permanent filters are created equal. Like any type of filter, there is a balance between dust arrestance and air resistance. Our filters have very low air resistance.
Even our most restrictive filters are no more so than a good pleated disposable filter.
With proper maintenance, you can expect your permanent filter to last at least as long as your HVAC unit. Some of our customers have been using their filters for over 15 years and counting.
No. All of our filters are electrostatic. They have special polypropylene media layers that build a natural static charge as air passes through the filter. The charge is broken and the dust is released when the filter is cleaned.
I’m using this filter in my woodworking shop to help filter the dust using my central dust filtration system. The custom filter fit perfectly in the unit and will help keep my lungs free of all the floating small dust particles that are produced from cutting wood. Best part is, I can just wash it and reinstall it, no longer throwing money away each time I need to replace the filter.
Sturdy and custom size was perfect
The filter is working correctly, but the delivery driver through the box over my fence on the concrete not sure if that when it was damaged.
Bought 2 filters 1 was bent I bent it back and is working ( not worth the hassle of trying to return it) does not look good but inside the AC no one will see it. The packing should have some air rap or extra cardboard to protect the filters, it was just placed in a box and shipped. Also the aluminum frame is very thin and bends by hand.
Standard size filters never fit properly and would end up bending within a few weeks. Max Merv9 fits perfectly and remains stable1
The MERV 9 is the only filter that does not pass all the dust and dirt there is in the air on a daily basis in Arizona, and it has about the same airflow resistance as a MERV 8.
Everything we do is built around trust and service.

I have been using my filter now for two weeks, and have noticed a difference in the air quality and coolness! My AC has been running more efficiently and the filter looks so much better than any previous filter I have purchased! The shipping is slow(made to order?) so unknowingly I ordered 2, and when I reached out they credited me for the second purchase, even though it was shipped. Highly recommend!
My order delivery address is clearly indicated, the front fmdoor is covered. FedEx delivered it to an apartment door (lower floor) with different street address that is uncovered. The package was buried in snow for two weeks. Never use FedEx!!!!!!!!!!!!!!
Filter is built sturdy and fit perfectly in my geothermal unit. Customer service was very prompt to answer questions about delivery of the filter during the Covid pandemic as well.
This is one of the best air conditioning filters that I have purchased.
My assessment is based on it's cost, permanent construction, easy cleaning, and it's filtration properties. Considering that you should change your air conditioning filters every two months, you can easiley see the return on investment. I Highly recommend it.
