I have purchased brand before and they are made very well. This purchase was for our den and I am going to start ordering for
the upstairs unit and the downstairs unit. I like the six pack price! Thank you Filterbuy.

The Product wasn't the advertized size

the product said it was 20X20 but it was actually 19 3/8ths by 19 3/8 which does not fit our machine.

Best Possible Reminder to Keep HVAC Healthy
on March 30, 2026
Posted by: Customer
Getting filters in the mail is the best possible reminder. You literally have to work around them until you're up to date. Super efficient. I have them changed in five minutes and my HVAC loves me for it.

Filter was too small it
on March 30, 2026
Posted by: Customer
Filter was too small it said 18x24x1 but it actually was about a half inch we had to put filler around it to fit it in the unit it's also thinner then the ones we used to buy we will see if it lasts the 3 months it's supposed to more to come
