Great Filter
on July 7, 2026
Posted by: Customer
I have been using Filterbuy filters for numerous years and change them out regularly. I have always been pleased with just how good of a filter they are compared to other filters that do not even compare in quality. The price is very reasonable so that is why I always purchase 12 filters at a time and I received them within 2 days of ordering. I will continue using Filterbuy so I do not have to worry about my filters being great!

Great filter
on July 5, 2026

The filter is so solid. I previously bought this flimsy filter that bowed immediately and got sucked up into the HVAC unit. After that terrible experience, I had to find a better option. This filter is excellent—well constructed and filtering out inpurities.
