Frequently Asked Questions
Everything you need to know about your water-care journey.
How do I know if I have hard water?

How often should I replace my filter?
For optimal results, we recommend replacing your shower filter every 3 to 4 months, or after 13,000 liters of water, to ensure maximum chlorine and mineral removal.

Yes, our filter is designed with a universal 1/2" thread that fits standard fixed, rain, and handheld showerheads.
