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.
