Common questions
When will I notice a difference?
The stronger pressure you feel on the first shower. Skin and hair need time: most people notice softer skin and smoother hair after one to two weeks of daily use.
What does the filter remove?
The 3-layer cartridge catches chlorine, limescale, rust and sediment before the water reaches your skin — the usual suspects behind dry skin, dull hair and itchy scalp.
How often do I replace the cartridge?
Every 2 to 3 months, depending on your water hardness. You can literally see it: the cartridge darkens through the filter window when it is used up. Refills are in our shop.
Does it work with weak water pressure?
Usually yes — the narrow micro-nozzles concentrate the flow, so the spray feels stronger than a regular head, even in older buildings. Extremely low building pressure has physical limits though.
How hard is the installation?
Unscrew your old head, screw haya. onto the standard hose. About 30 seconds, no tools, no plumber.
What if I do not like it?
You have 30 days. Email support@hayabath.com and you get your money back.
