Most manufacturers say every six months. That’s it. That’s the number. But let’s be real: who actually remembers to do that?
If you’re like me, you wait until the water tastes like a dusty sock. Or until the filter is so old it should be in a museum. Don’t be that person.
Set a reminder on your phone. Name it “Water Filter Shame Day.” It works, I promise.
But What If You’re a Super Weirdo (Like, a Heavy Water Drinker)?
If you live alone and drink one glass a day, your filter might last longer. But if you have a family of four who chug H2O like it’s a sport? Swap it every three months.
Filters have a literal lifespan, not just a calendar life. Think of them like a sponge that catches all the gross stuff. Eventually, that sponge gets full. And then it starts dumping the gross stuff back into your water.
Yummy. Who’s up for a second glass?
