Fit and install

What it does
What does Lull filter?
Lull reduces chlorine and its smell and catches rust and sediment. It also has a vitamin C stage, made for city water.
Does it soften hard water?
No. Lull doesn't soften water, and we won't pretend it does. It's made to reduce chlorine, which is what most people notice in their hair and skin.
