How often do I need to change my shower filter?Updated 24 days ago

Your Sans filter lasts roughly 90 days. There's no light or sensor to watch — it's time-based, so the easiest approach is to set a reminder every three months (or let a subscription handle it, below).

If you're on the heavier end of usage, or your water is especially hard, you may want to swap a little sooner. A good rule of thumb: if flow starts feeling weaker or you notice more scale around the nozzles, it's time.

If you'd rather not think about it, our filter subscription ships a fresh one to you every 90 days, and you can pause, skip, or cancel anytime from your account.
