Look a little closer.

The exterior rarely shows every surface that touches your food or water.

Follow the contact pathway

Trace the reservoir, tubing, seals, lids, filters, and other surfaces that contact what you eat or drink. Record the source for each material claim and mark anything you cannot verify.

A useful checklist

• Which parts contact food or water?
• At what temperature and for how long?
• Are materials specified for the exact model?
• What changes with wear and maintenance?

Use this checklist while reading a product page, manual, certification listing, or comparison.
