First of all, nobody wants to drink water that tastes like a swimming pool. If your tap water has chlorine, sediment, or even a hint of metal, guess what? Your customers will taste it—especially in your tea and espresso. A good filtration system removes these nasties, so your drinks taste crisp and clean, not like a chemistry experiment.
And here’s a fun fact: unfiltered water can leave mineral deposits in your expensive espresso machine. That’s like scratching a Ferrari with a key—expensive and totally preventable. A filter saves you money on repairs and keeps your equipment purring like a happy kitten. (A very expensive, mechanical kitten.)
