Merv 11 filters

These fit the 20x30 filter panel perfectly. Other manufacturers filters (20x30j are just a little to big and you have to bend the filter to fit it.

A filter that fits!

I've made the mistake of purchasing other brand filters, only to find they don't correctly fit the opening in the air return. These filters are a good value I wouldn't purchase anything else.

A filter that fits!

Honeywell brand filters are the only filters that fit the opening in my return. I made the mistake of buying a different brand when these were out of stock, and I will never make that mistake again!
