The reusable water bottle category is huge — and not all of them are actually safer than disposables. Here’s how we evaluate them.
Trust: 18/8 stainless steel + borosilicate glass
Both are food-grade, durable, and don’t leach. Stainless is lighter and travel-friendly; glass is the cleanest taste.
Trust with caveats: food-grade silicone
Excellent for travel + folding bottles. Look for platinum-cured silicone.
Skip: thin plastic with #7 codes, painted interiors, mystery linings
Even “BPA-free” plastics can contain analogues like BPS. For something you drink from daily, we recommend stepping up to metal or glass.
Three questions to ask
- What’s the interior surface?
- Is the lid easy to clean (no hidden seals)?
- Are replacement parts available?
Our top everyday pick: insulated stainless steel water bottle.
