Seriously, how often should you swap it? The official answer is every two months (or 60 tank refills). That’s the boring truth.
But here’s the fun part: your water is a secret traitor. Hard water has minerals that play dirty. If your tap water leaves crusty rings in your kettle, you’re in hard-water country. Change your filter every month there.
Soft water? You can likely stretch it to three months. But don’t test it. Coffee tastes like rebellion, not chalk.
The Science (Made Fun)
Every filter is a tiny bouncer for your mug. It kicks out chlorine, sediment, and that weird metallic tang. Imagine a nightclub where the bouncer is asleep. That’s your old filter.
Your Keurig is basically a robot barista. It’s begging you for a fresh filter. Ignore it, and you get bitter coffee and a machine that clogs like a grumpy drain.
Fun fact: a clogged filter makes your brewer work 20% harder. That’s like you running a marathon in flip-flops. Not cool.
