Perfect fit
on May 11, 2026
Posted by: Customer
I have been purchasing this filter by the dozen for a six month supply at our house. They are a perfect fit for the filter housing. They are also a perfect fit for us. We have a dog and a cat, and a persons with environmental allergies (just not to cats or dogs). These work great for us! Buying them a dozen at a time makes them an affordable choice given that we need a non-standard size.

Filters fit great, have been using this brand for over three years
I change filters every 6 months, don't use the HVAC that often.
