Your Tempest might come with a filter. If it does, the manual has a 10-page section about changing it. You’ll read it and feel overwhelmed. Then you’ll realize you forgot to buy a replacement. So you drink tap water from a fancy machine. We’ve all been there.

One quirky line in the manual says: "Do not use the filter if it smells like chlorine." This implies you have smelled chlorine. And that you would sniff a filter. You probably will.
