Why we exist
Building in public, on purpose.
01
The category has a credibility problem.
Search for a shower filter and you get twenty-stage cartridges, lists of a dozen contaminants and dramatic promises about hair. Very little of it explains how the product works, and almost none of it says under what conditions any of those numbers were measured. We found that genuinely annoying, which is roughly how most products start.

02
So we are building it backwards.
Most brands in this category launch first and test later, if at all. We are doing the reverse: settle the hardware, test the finished production configuration, then write the claims from whatever the results actually say. It is slower and it means this site is thinner than a competitor's. That is the trade we chose.

03
You are early, and that is the point.
The founding list is not a mailing list with a nicer name. Finish, cartridge cost and which market we ship to first are all still open, and the people on the list are the ones we ask. When testing results come back, founding members see them before they become marketing.
