NO. . I bought 17. 25 x 21. 5 x 1 MERV 13. These are the ones that fit my air handler and these are the ones that were shipped. You guys are really great. I've been recommending Filterbuy for a long time now.

Its just been a few days since I replaced my regular filter with the Merv 13. Im a bit amazed at the difference. Allergies have been plaguing me for the last few months. Since I replaced my regular filter with the Merv 13 I have been feeling much better. Not so groggy in the morning. The headaches have disappeared and sneezing and coughing are not nearly as bad. I highly recommend these filters

As far as I can tell, these filters are as good as it gets and they save me a few bucks. I order direct and they ship quickly. Never an issue. I will continue to use these filters as long as I get this kind of quality and service.

Up until now have been using MERV 8. With the smoke from Canada decided to upgrade to the13 and found price sizing and were all I could ask for .What at this point I do not know and my furnace supplier could or would not say is if I would have enough pressure drop to negatively affect my furnace out performance.Am hoping the four inch pleated will do the job. Have just put in and seem to have at least a happy wife.
