Built because I kept forgetting
I'm a homeowner, not a maintenance guru. But I got tired of the same hits: HVAC filter clogged in July, smoke alarm chirping at 2 a.m., pool water cloudy right before people come over, and my wife asking if I changed the fridge filter yet. (I had not.)
Every time — I knew what to do. I just didn't know when. The filter size was written on a Post-it somewhere. Last year's Amazon order was buried. And I wasn't signing up for another $9/month app to guilt me about chores.
So I built CheckingFilters.com: a dead-simple list of the stuff around your house that needs swapping on a schedule. Punch in your sizes once. Get one email when it's due. Tap to reorder if you want. Mark done. Done.
No giant product database. No monthly bill — pay once for lifetime if you want unlimited reminders. The whole point is staying ahead of the boring maintenance so you're not paying for emergency HVAC calls or standing in an aisle guessing filter sizes.
If it saves you one sweaty summer night or one trip to Home Depot where you buy the wrong filter — it's worth it.
