Arizona Dust and Dirt

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.

Match Game 2023

Filter was an exact match to the one installed by Villara Systems. I was taking a risk as the Mfg referred me to a Wholesale Supplier whom I had no account. I used your website and it looked like an exact match, finish & dimensions and it turned out to be correct. It was promptly installed and doing it’s job!

So Far So Good

We have had our new filter a short time but are very happy so far. It seems to be made very well and to our specific measurements, as it was custom made.

Great filter very well made

I love my new filter I'll never have to buy another one again I'm so happy that I bought it and I hope everyone gets one

Amazing Filter

Use to have a Bo Air filter and now have purchased 2 of these never buy filters after purchasing a new AC system. I use them by swapping out the dirty one and sliding in the clean one. Great system , never buy paper frame filters.

Furnace filters

Made super good delivery was great just remember that they are made to order so takes a little while to get them

As advertised, just installed. Will re-evaluate in six months after several cleanings.

True to the name

I have had the MaxMerv9 in use for 5 years. It has worked great! I wash it once a month and it cleans up great. I will never need to buy another filter.

Wrong size

Are you a robot?
I responded with a plea for some help, as I ordered the wrong size and wondered if you could exchange 19x15 filters for 18x15 filters.
