Water Filter Decision Assistant Phase-1 Pro Tool

Answer 5 questions. Get a clear, explainable recommendation — plus what to avoid and realistic cost expectations.

Step 1/5

1) What’s your main water source?

This changes the “default risk.” Well water usually needs pre-filtration. City water usually needs taste/chemical reduction.

City / MunicipalCommon issues: chlorine/chloramine taste, aging pipes, occasional advisories.

Private WellCommon issues: sediment, sulfur odor, iron, nitrates, bacteria risk (varies).

Not sureWe’ll recommend a safe default that avoids expensive overkill.

2) What’s your #1 water problem?

Pick the one that would make you fix it first. This prevents “buying everything.”

Bad taste / chlorine smellWater tastes like pool / metallic / “off,” ice and coffee taste worse.

Health concerns (lead / chemicals / baby use)You want stronger reduction of contaminants (not just taste).

Stains / scale / appliance damageHard water spots, scaling, orange/brown stains, soap not lathering.

Rotten egg / sulfur smellStrong odor (often well water). Usually not solved by pitchers.

Low pressure / filters clog fastFlow drops quickly; sediment likely needs upstream treatment.

Not sure — just want safer waterWe’ll give a conservative recommendation that doesn’t waste money.

3) Household size?

This affects flow rate and how quickly filters get exhausted.

1–2 peopleLower daily demand; simpler systems often suffice.

3–4 peopleMedium demand; under-sink systems shine here.

5+ peopleHigh demand; avoid tiny pitchers and slow RO without capacity.

4) Do you own or rent?

Renters usually shouldn’t drill or install permanent whole-house equipment.

OwnYou can consider under-sink RO or whole-house options if justified.

RentWe’ll prioritize removable filters and no-drill options.

5) Upfront budget (realistic)?

We constrain recommendations so you don’t get upsold into maintenance pain.

Under $100Works only for limited goals (usually taste on city water).

$100–$300Best value zone for under-sink carbon & countertop systems.

$300–$800Opens RO options and higher-capacity setups.

$800+Whole-house + specialized treatment becomes realistic (if needed).

Important: This tool is a decision assistant, not medical advice. It suggests filter types based on common household patterns and your answers.
