Out-of-style filter jugs
If you don’t have a Brita jug at home, you should definitely get one. They work great at removing invisible particles from tap water, which would otherwise end up in your bodies and potentially causing harm. However, make sure you shop at a retail store or online shop that sells stuff from this century.
Brita jugs can last a long time, which is what makes them perfect for having around. However, if your filter jug is over ten years old, first of all, congratulations for taking such good care of it. That said, swap it out for something smaller or for a filter tub that fits inside of your refrigerator.
