Different filtration approaches are built differently. Compare the questions, tradeoffs, and options that fit your home.
Water use can vary by system and installation. Review the details of the approach you are considering.
A current water report can help you ask better questions before selecting a filtration option.
The right choice depends on your water source, household needs, and the details of the system you are considering.
Use the comparison as a starting point, then review your own water information before deciding.
Compare system details with your household’s water needs before making a decision.

One published test
A scoped before-and-after result.
In one independent Tempe before-and-after test of the complete under-sink system, quantified PFAS fell 97.44–99.93%; several measured PFAS were non-detect after filtration.
PFAS exposure is associated with health concerns; review the EPA PFAS guide for public-health information. This result is one test, not a prediction for other water sources.

One report
One Salt Lake City PFAS result was about 400× an EWG advocacy health guideline while legal limits were met.
Review the source details, reporting period, and the facts that apply to your own water system before making a filtration decision.
One published test
A scoped pH result.
In one Tempe under-sink test, pH measured 6.83 before filtration and 8.21 after.
That result is specific to the tested water and system; it is not a health-outcome claim.

Why it's worth it
The difference you feel at home
A Sentry H2O system starts with the questions that matter at home: where you use water, what your report says, and which options you want to compare.
Water for everyday routines
Explore under-sink and whole-home filtration for the places your household uses water most.
Options for shower routines
Consider shower filtration alongside the rest of your home’s water plan.
A better starting point
Use your water report and household needs to compare the available options.
Less reliance on single-use bottles
A home water plan can help you consider alternatives to bottled water.
