Why Now

America’s water is getting harder — and dirtier.

The numbers behind the category are not subtle.
Hard water is the national default, emerging contaminants are showing up at the kitchen tap,
and the pipes delivering it all are aging faster than they’re being replaced.

Ca
85%
of U.S. homes are supplied with hard water, per analyses of U.S. Geological Survey hardness data.
F
45%+
of all U.S. tap water is estimated to contain at least one PFAS “forever chemical,” according to a USGS study.
Pb
Millions
of lead service lines are still delivering drinking water to American homes based on EPA estimates.

The Htruo Difference

Connected to your plumbing architecture — not just your Wi-Fi.

Most water treatment equipment is installed, then trusted on faith. HtruO is engineered around a different premise: a system can only work flawlessly if it knows — continuously — what the water is doing. That’s why integration with the home’s plumbing architecture isn’t a feature. It’s the condition for flawless.

01 · Measure

Know the water

Inlet sensing profiles hardness, TDS, pressure, and flow in real time — because your water changes by season, by source, and by hour.

02 · Treat

Respond to reality

Regeneration and filtration keyed to measured demand, not timers and guesses — less salt, less waste, no quiet drift in performance.

03 · Verify

Prove the result

Post-treatment sensing confirms outlet quality against setpoint. If performance drifts, you know before your fixtures do.

04 · Protect

Defend the system

Treatment, heating, and monitoring on one data layer protect each other — and the entire plumbing system they serve.

Coming from Htruo

Three product families. One measured standard.

02
Softening

Smart Softening Series

Demand-based softeners that regenerate on the grains actually exchanged — not a timer — cutting salt and water waste while holding a continuously verified soft-water setpoint.

03
Scale Defense

Engineered for Tankless

A softening and scale-defense line purpose-built for tankless water heaters, protecting the compact high-efficiency heat exchangers where mineral scale does its most expensive damage. Pairs natively with Trutankless.

Final series names, configurations, and specifications will be announced at launch.

The Parent Company

Award winning engineering

Trutankless pioneered the connected electric tankless water heater — hardware designed around live data, real-time diagnostics, and app-level control.

HtruO extends that same engineering philosophy to everything else your water touches: filtration, softening, and scale defense for the whole home.
