We're on an old well and I'd been wondering. It takes about a minute and you match the colors to the chart. It isn't a lab test and they don't say it is, but it told me I should get the iron looked at.

Everything looked okay, which was nice to know.

Tested the rain barrel out of curiosity. Glad I filter it.

How It Works
Dip a strip in your water. Wait about a minute. Match the colors to the chart on the bottle. It checks 17 factors, including metals and chemical indicators.
What It Does, and What It Doesn't
It's a quick check, not a lab report.
A clean result doesn't prove water is safe to drink. If a result worries you, or you suspect chemicals, don't drink it. Stick to stored water and call your water utility or a certified lab.
Shipping
Standard shipping is $4.95 and Express is $9.95. Delivery times are on our Shipping and Returns page. Every order ships the next business day, tracked and insured.

You can't tell by looking
A filter straw removes bacteria and protozoa. It doesn't remove chemicals or heavy metals, and CDC says boiling can't make chemically contaminated water safe. So it helps to have a way to check when something seems off.

Questions people ask
What does it check for?
17 factors, including metals and chemical indicators.
How fast is it?
Results take about a minute.
If the test looks fine, is the water safe to drink?
Not necessarily. It's a quick check, not a lab report. It can't promise water is safe. If you suspect chemicals, don't drink it.
Does it replace a lab test for my well?
No. If you're on a well and worried, use a certified lab. This is for a quick look at home or in an emergency.
Does the straw fix what this finds?
Not if it's metals or chemicals. The straw removes bacteria and protozoa. It doesn't remove viruses, chemicals, heavy metals or salt.
How fast does it ship, and what if I change my mind?
