How do I fit the A1378?

No tools, a few minutes: 5 steps, listed on this page with the replacement video where the maker has one.

What happens if I don't change it?

Spent carbon stops removing odours and discolouration, and clogged pads slow the flow, so the filter moves less water through the tank.
