Test your tap water for microplastics at home. Same method used by research labs — you just run it yourself.
What's in the box:
• 2 complete tests (tap vs. filtered, or any 2 sources)
• Nile Red fluorescence stain (pre-measured)
• Syringe + filter for sample collection
• Blue LED light + orange viewing filter
• Step-by-step instructions
How it works:
1. Fill the syringe from your tap
2. Add the stain, wait, push through the filter
3. Shine the blue light — microplastics glow pink
10 minutes of hands-on work. Upload your photo and we count the particles.
Most popular use: testing whether your water filter actually works. Run tap water, then filtered water, and see the difference
with your own eyes.
Works with any water source — tap, well, bottled, filtered, fridge, pitcher, whole house.
