"I ordered 4 air filters from them and I got 3 the correct size and one incorrect size. I had to take multiple photos of the incorrect filter, including using a tape measure, and finally I got them to agree to send me a replacement. And despite the invoice listing the correct size, they sent me another wrong size....not even close. This time it took over a week of hounding them, them requesting multiple photos, until I left a VM saying "You screwed this order up twice, now I just want a refund. Do the right thing!" No response. So I called again, and now they decided to refund me, except they refunded me the price of the wrong filter which was $20 less than the one I ordered. But by now I was so tired of arguing with them I just let it go. DO NOT USE THIS COMPANY!! BTW, these are the same people that also go by the website Filtermonkey.com. BEWARE!!!"
