As a NASCAR driver, Blake Koch knows the value of regularly changing the oil in his vehicles. He knows dirty oil will affect his motor and his race results, so changing his oil was easy to remember.
Blake has a little more trouble with his home’s air filter, however. He can never remember how long it’s been since he changed it, and when he remembers, he either doesn’t have a new one to replace it with, or he remembers it at the store, where he doesn’t remember the right size.

First of all, I did a Twitter contest for my followers to win a FilterTime hat and shirt, and to enter you had to tell me the last time you changed your air filter. I was shocked at some of the responses and how long people have gone without changing their air filters, but the majority was within the past 3 months, which is a good thing. Some people said it has been a year, some said 2 years, and a few people said they couldn’t even remember. It’s not an easy thing to remember, it’s out of sight out of mind. That’s why I started FilterTime.com. To take remembering to buy air filters off everyone’s to-do list for good.
