For the thing you drink all day

Your biggest exposure is probably in your glass

One liter of bottled water can hold about 240,000 plastic particles, most of them nanoplastics small enough to cross into tissue. Water is the highest-volume exposure route for most people. Scan your water, bottles and filters, and find lower-plastic options near you.

How the water audit works

  1. Scan what you drink

    Bottled brands, your reusable bottle, the kettle, the filter pitcher. Each gets a score with its reasons.

  2. Compare against tested brands

    Our bottled water database ranks brands by measured particle counts from published lab tests.

  3. Fix the routine, not just the bottle

    Hot car bottles, worn filter cartridges and plastic kettles all move the number. The app tells you which matters most.

What the research says about water

Water scores lean on the strongest measurement studies in the field, linked inside every result.

Bottled vs tap

Bottled water typically carries far more particles than tap. Scans show the gap for your specific brands.

Filters that actually help

Some filters measurably reduce microplastics, some do nothing. Tested lists show which is which.

Reusable bottle materials

Glass, steel and plastic bottles age differently. Scratched plastic bottles shed more with every wash.

Refill stations near you

The nearby map surfaces refill stations and better options around you, so the low-plastic choice is also the easy one.

Plastic Coach

Ask the Plastic Coach

A coach trained on the same research as the scanner. Ask it anything about your results, in plain language.

Is my bottled water actually a problem?

Depends on the brand. Scan it and I will show you where it lands against lab-tested brands. If it is high, the swap that removes the most exposure is usually a filter plus a steel or glass bottle.

My filter pitcher is 4 months old. Does that matter?

Yes. Past the rated life, filters stop capturing what they were catching before, and a degrading cartridge can shed. Replace the cartridge and your water score usually recovers immediately.
