Based on previous filter performance, I feel the newly ordered, although unused, will perform equally as well.

SIZED INCORRECTLY
on December 24, 2017
Posted by: Christy Q.
The 4 filters that I purchased sized 24 cx 36 are not 24 x 36 although they are clearly marked. They, in fact, measure 25 x 36 and do not fit. I need to get a refund.

Solid product at a Great Price
on December 20, 2017

Received the product in a timely fashion exactly to specifications. A robust custom filter that held up well despite all the cajoling it takes to install in my ceiling air system. My one caveat is that the sizing increments are not uniformly in 1/8 inch increments - which would make a world of difference in ensuring a good fit. Fantastic product! Will be a return customer when this one wears out.

They came in a timely fashion and were exactly as described. They fit great and hoping they will work great as well. So far so good.

I have not used the filters yet so I am unable to rate them. Get back in touch in four months.
