Forget the manual for a second. Your senses are a decent backup. If the water tastes flat, metallic, or smells like a damp basement, the filter is done. If the flow slows down to a trickle, it’s clogged. Don’t be a hero—just replace it.
Also, check your local water report. Hard water? High chlorine? Your filters will die faster. I live in a city that loves chloramine, and my Brita cartridge is toast after 5 weeks. Your mileage will vary, and that’s okay.
Final (Slightly Sarcastic) Advice
Look, nobody wants to spend money on water filter cartridges. They’re like printer ink—overpriced and annoying. But think of it this way: you are paying for peace of mind. A $20 cartridge twice a year is cheaper than a case of bottled water or a plumber’s visit for a clogged fridge.
So, next time you pour that glass of water, ask yourself: How long has this filter been alive? If you’re guessing, it’s probably time. Change it today. Your future self—and your taste buds—will high-five you. I’ve already replaced mine. The water tastes like victory. Or at least like not-metallic.
Now go check your filter. I’ll wait. 😉
