This clever bottle filters as they sip, reducing lead and removing 99.9%* of microbial cysts. It also reduces the taste and smell of chlorine to make cleaner, tastier water they’ll enjoy all day, every day. And by making sure water always tastes great, you’re helping them develop healthy preferences that will last as they get older. The bottle is easy to clean in hot, soapy water or on the top shelf of your dishwasher - but please remove the filter first. This should not be cleaned or washed - it looks after itself and will last for up to 2 months before needing to be replaced.
