Clean water and air are requisites for human health.

Requisit is building verifiable home hardware for the fundamental inputs to human health.

Measure. Build. Prove.

Named for what’s necessary.

Requisite: necessary, required. The water you drink and the air you breathe are not upgrades or wellness add-ons. They are requisites, not extras.

Requisit makes home hardware for them, starting with an under-sink reverse-osmosis purifier and then indoor air, so that what it does can be measured and what we say about it can be checked.

Proof over wellness.

Measure
Each product starts from an observable problem and a defined performance measure. If we can’t measure it, we don’t build for it.
Build
Established components where they lower risk, and our own engineering where it shapes the experience. We use AI to move faster, never in place of testing.
Prove
Independent testing against recognised standards, so performance claims rest on published results rather than branding. Until a result exists, we don’t claim it.

Small team, human sign-off.

A small founding team that uses AI for research and engineering. A founder makes every decision touching safety, money or public claims.
