This is best filter company. Great for a number of reasons including price, and very great communications about my purchase and recommendations.

My 18 by 24 inch filter is short in both dimensions and leaves a gap

My 18 by 24 filter is short in both directions and leaves a gap. I need a true 18x24 filter or a refund. I am very disappointed and have never run into this!

So far we have been impressed with our filter buy filters, they fit well, and seem to do the job. They are well made and the fact they are shipped once a year is wonderful.

I am so happy we decided to order several at a time, rather than one at a time. This was a suggestion by our PM company after we left our filter in too long. We will be doing this on a regular basis now!

I like your product but I need you to STOP sending filters because I have plenty in stock.
PLEASE DON’T SEND MORE UNTIL FURTHER NOTICE.
