Great Filter

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

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.

Hopefully Will Fit

We bought these to replace the Filtrate filters. We have typical Florida ceiling vents. The Filtrate are VERY hard to insert. Read these are “smaller” and much easier to insert. We are seniors and do not feel safe climbing up, having to force the Filtrate in. We will begin using the Filterbuy next time we change them in a few months.
