The 16X20 that fit my unit perfectly!!

I had to find out the hard way that 16X20 filters are not alike. Good thing we keep the first filter and found out the true measurement. These filters fit perfect and provide a cleaner system for our ac/Heat unit. glad we found your product.

The right fit

These are the only filters I have found that actually fit in my heater. Actual size is perfect!

Merv 10 Air Filters

I have purchased 2 cases and I really enjoy how well they work. I was replacing my filter once a month like recommended. After using these Merv 10 air filters, my service company says I can change the air filter seasonally.
