I used to keep a LifeStraw on me. I'd be worried about it exceeding it's temperature range when kept in a locked car during the summer.
Probably a valid concern. My garage stays cool, but at work i have to leave my truck parked outside for weeks or a couple months at a time.
Do lifestraws work?
I've seen reviews stating that they can't even remove food coloring from water..?
They might not. I've never really cared to check. I figured they'd be better than nothing but not perfect. They're not particularly expensive, so it seems like a worthwhile investment to me.
