Even though my grandpa is an occasional smoker, I still worry about the second-hand smoke lingering in the air when my kids and I go visit him. Because we live nearby, I try to stay on top of making sure he has clean air filters, but I don’t always remember. With AirFilterReminder.com, I get a simple text each month that reminds me when his air filters need to be changed. It’s one step in the right direction.
