20x32x1 MERV 13 Pleated Air Filter

I have an odd size HVAC return and they fit perfectly. One of our kids has asthma and the monthly delivery makes it impossible to overlook the filter change.

Buy 4... Have them auto shipped annually, and set a reminder to change it every 3 months. Your A/C will love you, your allergies will love you, and you are getting incredible filters at the best prices available. Customer service here is second to none. I accidentally chose the wrong size the first time... They asked me to donate the ones I received to someone in need, and sent me the size I needed, with only the cost of the difference in size. I will never look elsewhere for air filters again. Thank you for a wonderful buying experience.

I order the Merv 13 because it covers almost every dust partical you can think of.

Fit perfectly. Difficult size.

filter fit perfectly. the shipping time was reasonable, but could be improved. overall it has been a positive experience and i will purchase again from filterbuy when the time comes..very pleased with the filter so far.
