FAQs
Answers about using the OTTO Water Quality Test to quickly compare water sources and see visible differences in clarity and overall condition.
What is the OTTO Water Quality Test?
OTTO is a quick, visual water-quality demonstration designed to help you compare water sources (tap vs. filtered, RO, RV, etc.) and spot visible differences in seconds.
Does OTTO identify specific contaminants?
No. OTTO provides visual feedback and is best used for comparisons and monitoring changes. It does not identify or quantify specific contaminants (like lead, PFAS, or pathogens).
For specific contaminant detection, use certified lab testing or targeted test kits.
How do I use the OTTO Test?
Fill a clear cup with water, add the recommended number of drops, swirl gently, and observe the change. For the best comparison, test two samples side-by-side (tap vs. filtered).
How long does it take to see results?
Most results appear within seconds. In some cases, a clearer comparison may develop after a short moment of settling.
What should I look for in the results?
Look for visible differences such as:
- Clarity changes (more/less cloudiness)
- Discoloration or tint differences
- Particles/sediment that become easier to notice
The goal is a clear before-and-after comparison, not a lab-grade identification.
Why do results vary by location or season?
Water chemistry changes based on the source, treatment method, pipe conditions, and seasonal shifts. For consistency, compare samples from the same source at the same time.
Can OTTO confirm my water is “safe” to drink?
OTTO is a visual demonstration and cannot certify safety. If safety is a concern (wells, springs, unusual taste/odor, boil notices), use certified laboratory testing.
Can I use OTTO to check my filtration system?
Yes. OTTO is great for a quick before-and-after comparison to see whether your filtration setup is making a noticeable difference over time.
Is it suitable for RV, travel, well, or spring water?
Yes. It’s especially useful when checking unfamiliar sources—RV hookups, campground water, travel locations, and private sources—so you can quickly spot visible changes.
How should I store the OTTO Test solution?
Keep the container tightly closed, store upright, and avoid extreme heat or freezing. Store out of reach of children and follow any label guidance.
Any tips for the clearest side-by-side comparison?
For the most consistent results:
- Use the same cup style and same water volume
- Use similar temperature samples
- Swirl both samples the same way
- Use clean cups to avoid residue
OTTO is a visual demonstration tool intended for comparisons and education. It does not identify or quantify specific contaminants, and results can vary with source-water chemistry and procedure.
