MaxMERV9 - CUSTOM SIZE

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.
