Great filters. Best of all I don’t have to think about it. They automatically come in the mail and is a great reminder to replace the filters on a regular basis.

I purchased 4 of these

I purchased 4 of these last year but didn't create an acct. I didn't pay close attention but I thought the pleats were evenly spaced. These, that I purchased this year are not. The one that measured range from a1/2" to 1-1/2'. and they are placed in the frame crooked. I have an old flip phone and cannot provide you with pictures nor video. otherwise, a GREAT filter!!

Our HVAC company confirmed that Filterbuy is their source. The prior home had electronic filters to wash in the driveway.
Much cleaner!

I’m happy with these guys. It comes when it’s supposed to, they’ve made changes to the packaging to make it more robust over the years, I’d recommend.

I think they do a great job. We live in the high step desert and it can get very dusty. Especially when the wind blows. Keep up the good work.
Thanks
