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 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
