These were purchased as a result of struggling with allergies in Florida. They have helped to purify our air and mitigate incoming allergens.

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.
