If you’re looking to escape into the woods for a hiking, camping or backpacking trip, it’s never a bad idea to be prepared for purifying your own water — especially if you’re heading way out into the backcountry.

For this task, there’s the LifeStraw personal water filter, which removes bacteria from water so well it goes above and beyond the EPA’s standard. (Hint: It’s also great to have in your emergency preparedness kit, just in case.) And right now, it’s back down to the lowest price we’ve seen in a year over at Amazon for Black Friday.

The LifeStraw is a simple, safe way to ensure you’re drinking clean water wherever you are. This is the lowest price we’ve seen on the LifeStraw since Black Friday of last year.

You don’t need batteries or a charger for this handy personal water filter, which purifies up to 1,000 gallons (or 4,000 liters) of water. (It’s even available in squeeze bottle form.)

LifeStraw does a very effective job of getting rid of the bad stuff: It removes at minimum 99.9999% (yes, four decimal places) of waterborne bacteria and 99.9% of waterborne protozoan parasites, and it filters water up to 0.2 microns. Plus, it doesn’t use iodine or chlorine to purify, so you don’t get a weird taste in the water; instead, it uses membrane microfilters made from fibers that trap all the gunk to just let clean water through on the other side.

And it’s not going to drag you down. This personal filter weighs just 2 ounces to make carrying it on the trail super easy. It also never expires, so you can prep ahead with peace of mind.

Not to mention, it’s one of our readers’ favorites. In fact, it was an Underscored top seller from Amazon in 2022. So buy yours now and drink up the savings before this deal expires or stock runs out — and be sure to peruse LifeStraw’s other discounts on everything from water pitchers to water bottles, also happening now.
