23.25x29.25x4 MERV 13 Pleated Air Filter

good stuff

I have been buying a large 4 inch filter from a mom & pop business about 1 hr away, for many years. As shipping costs have gone up...so has the filter prices making one filter a little less than $100 including shipping costs. They claimed these are once a year filters, but I always start seeing dust after about 3-4 months. Not sure why I waited so long to find an alternative supplier. I think because I was convinced they were custom made size. Thank goodness I did. I found FilterBuy and not only were they very consumer friendly, and a lot less expensive, (I got 4 for a little over $100), they also kindly and swiftly dealt with a shipping problem immediately. You guys rock!!
