How to Swap to Non-Toxic cups:
Here's how to swap to non-toxic cups:
What to know about cups
The material your cups are made of matters because they're in direct contact with the liquids you drink — often multiple times a day. Some materials are naturally inert and won't interact with your beverages, while others may leach unwanted substances, especially with hot drinks.
- Hot beverages increase the chance of materials releasing substances into your drink, so cups used for coffee or tea deserve the most attention.
- Cups you or your kids use daily are a good place to start since frequency and direct mouth contact make them a higher priority.
Check the cups you already have
Look at the materials your everyday cups are made from. Welpr prioritizes glass, stainless steel, and ceramic or stoneware that has been tested free of lead and cadmium. Plastic cups or cups with plastic linings are worth flagging.
- Flip your cups over and check for material markings — look for terms like 'lead-free,' 'cadmium-free,' or '100% stainless steel.'
- Set aside any plastic cups, travel mugs with plastic interiors, or older ceramic mugs with cracked or worn glazes to review first.
Use your current cups more safely
If you're not ready to replace all your cups right away, a few small changes can make a difference. This is especially helpful for plastic or older ceramic cups you still use regularly.
- Avoid using plastic cups for hot drinks — reserve them for cold or room-temperature beverages only.
- If you have older ceramic or hand-painted mugs with visible glaze wear or crazing, switch those to decorative use and drink from newer, tested cups.
Choose cleaner replacements
When shopping for new cups, focus on simple, non-reactive materials. Glass and stainless steel are among the safest options. Ceramic and stoneware are great choices too, as long as they're confirmed free of lead and cadmium.
- Look for cups that clearly state their materials and avoid any with plastic touching the drinking surface — BPA-free plastic is still plastic.
