Hard water
White scale on fixtures, spots on dishes, soap that won't lather, stiff laundry.
Possible causes
- Dissolved calcium and magnesium picked up from rock and soil — the most common water condition in the U.S.
What evidence helps
A measured hardness value: your utility's reported range is a starting point, a $12 strip or a lab test gives you a number for your home.
Honest next steps
Get a number first
Softener sizing depends on measured hardness, household size and bathrooms — never buy on a guess.
Compare softening options
Ion-exchange softeners address hardness itself; filters don't. Conditioners alter scale behavior with different trade-offs.
Owner of a whole home?
A local professional can measure hardness during a visit and quote a properly sized system.
Hardness is a comfort, cost and appliance-lifespan issue — not evidence your water is unsafe.
