Sampling & lab/strip analysis
How a Water Test Kit works
The first step — measures what's actually in your water so you treat the real problem.
Typical cost: $15–$200 per kit
How it works
You can't choose the right system until you know what's in the water. A test kit measures the actual levels of contaminants and nuisance minerals so treatment is matched to your home, not guessed.
Quick test strips give an at-home read on hardness, chlorine, pH, iron, and nitrate. For health-related contaminants like lead, arsenic, or PFAS, you collect a sample and mail it to a certified lab for accurate numbers.
The results tell you which technology you need — softener, carbon, RO, oxidation, or a combination — and how to size it (WQA / EPA).

What each part does, in the order water moves through the system.
- 1Sample bottlesCollect clean samples to send to a lab.
- 2Test strips / reagentsGive fast at-home reads on common parameters.
- 3Color chart / appTranslates a strip's color into a measured value.

What it addresses
- Removes nothing — it measures, so you treat the right problem
- Reveals hardness, chlorine, iron, nitrate, pH, and more
- Lab kits quantify lead, arsenic, and other health contaminants

Pros & cons
Pros
- Cheapest, highest-leverage step — stops you buying the wrong system
- At-home strips give answers in minutes
- Lab kits deliver accurate, health-grade numbers
Cons
- Strips are approximate — not a substitute for a lab for health risks
- Lab kits take days to return results
- A single sample is a snapshot; water can change over time
Best for
Everyone — the right starting point before spending on any treatment system.
Sizing basics
- Match the kit to your question: strips for hardness/chlorine, lab for lead/arsenic/PFAS.
- Well owners should test annually and after any change in taste or color.
- Use the results to size and choose every downstream system.
