Essential to campers and hikers, a dependable water filter should accompany any trip to someplace where the drinking water could be an issue. Portable filters tend to be bulky, but not the LifeStraw Personal Water Filter. It’s been recommended by The New York Times’ Frugal Traveler, Lucas Peterson, and filters up to 1,000 liters of contaminated water without chemicals like chlorine or iodine (so it won’t add any weird flavors to your drink). It also functions without batteries or moving parts. For Prime Day, you can score one for just $10, which is 43 percent off Amazon’s regular retail price of $17 (it goes for $20 if you buy direct from LifeStraw).
