UNDERSTAND YOUR OPTIONS
The right solution starts
with the right question.
Compare common approaches using appropriate water test results. Product purchase, installation help or more testing may fit. These are starting points, not equipment recommendations.
Mineral buildup? Compare product, testing and professional paths →Water softeners
For measured hardness and mineral buildup.
What it can address
Remove calcium and magnesium that cause hardness.
Know the limits
Do not remove disease-causing germs. Hardness treatment is separate from water-safety testing.
Find water softeners providers →Read the related problem guide →Helpful resources for this categoryWater filtration
For specific substances, tastes or odors.
What it can address
Depending on the media and model, address specific particles, tastes or odors.
Know the limits
No single filter removes everything. Most pitcher and refrigerator filters are not designed to remove germs.
Find water filtration providers →Read the related problem guide →Helpful resources for this categoryReverse osmosis
For specific dissolved chemicals at a tap.
What it can address
May reduce certain dissolved chemicals when the model supports that use.
Know the limits
A unit at one tap does not treat the whole home. Confirm the measured need and the model’s reduction claims.
Find reverse osmosis providers →Read the related problem guide →Helpful resources for this categoryTest before choosing treatment
Taste, smell and clarity cannot establish water safety. Identify the concern, check specific product reduction claims, and plan for maintenance and follow-up testing.
