Good to know
Questions, answered
Yes. It screws onto the standard half-inch hand-shower fitting used across New Zealand, the US and Canada, and installs by hand in a couple of minutes, no tools or plumber. If your hose is an unusual size, a low-cost half-inch adapter from any hardware store sorts it.
It reduces fine sediment and chlorine taste and odour. It is not a drinking-water filter and does not soften hard water minerals, its job is a gentler, fresher-feeling rinse.
Every few weeks, depending on your water and how often you shower. One cartridge comes fitted in the head; a 20-pack of refills keeps most households going for around a year.
No. The spray holds a strong, even flow while it filters, even on lower-flow showers.
