Cleaning your water bottle is a pain and chore, but there’s nothing grosser than a smelly contraption to drink from. Luckily, there are a couple of water bottles on the market that can clean themselves. That’s right, these water bottles disinfect themselves to remove any nasty smells and bacteria while you use them.

Our own shopping experts found a handful of top-rated, self-cleaning water bottles that may be right for you. While these water bottles are more of a splurge, we think a clean and safe drink of water is worth it.

(Note: While the water bottles below can deactivate germs, they cannot remove forever chemicals and heavy metals like lead. For a more complete water filtration solution, check out the LifeStraw Go Series water bottle with built-in filtration.)

Larq Bottle PureVis

This water bottle can eliminate 99% of bio-contaminants such as E. coli from your water and bottle. Just press its cap and shake the bottle to clean.

It’s rechargeable and will stay clean for up to 30 days.

This bottle is available in insulated (keeps water cold for up to 24 hours or hot for 12 hours) and non-insulated versions, plus two sizes. The non-insulated bottle is noticeably lighter.
