Filter quality seems good enough. I just installed one today, however the size isn't actually 24". It 23. 5 and is almost too small to fit the filter box properly allowing a small slit to be unfiltered.

Filters work fine. They’re basic and do the job. I do want call out that the website made me think I would receive them in 2 days but that did not end up being true.

Unlike the hardware store, my size is always in stock

I've gone to my local hardware store on multiple occasions to find my size sold out. So my filters are doing extra duty while I wait. This will eliminate that problem. I set a reminder in my calender to go down and change it out. Now FilterBuy needs to put a QR code in the box so when I pull the last one out I scan the code and click a reorder button.

I'm very pleased with my purchase of six 16x25x1" filters. They were shipped with adequate wrapping to protect them from any danagevduring handling. The price is also a plus!
