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.

Affordable and effective

I love these filters. Affordable and effective. It's amazing to see how much they have collected when it's time to change them. The subscription service is great. A little extra savings and a subtle reminder that you forgot to change them. LOL. But I usually notice when it's time if I forget, I find myself sneezing and having itchy eyes in the house. Which always improves once I change them Highly recommend these and Filterbuy

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.
