our story
why we built coastflow.
the mission is simple: make tap-mounted filtration easier to understand, easier to buy and easier to live with.
the mission
we like products that remove friction rather than add another routine. coastflow is built around the tap you already use, with a replaceable cartridge format instead of another benchtop appliance.
so coastflow isn't trying to reinvent water. it's trying to remove the friction between good tap water and the glass in your hand.
how we design
one job, done well
it filters where you pour. no app, no extras, no features it doesn't need.
form follows the tap
the shape comes from the fitting and the flow — not from a marketing brief.
the display stays useful
the built-in display includes a filter-life indicator. when the life bar turns red, it's time to replace the cartridge and reset the display.
serviceable, not disposable
when the cartridge runs out, you swap the cartridge. the object stays on the tap.
