LifeStraw Peak Series – Replacement Membrane Microfilter Compatible with Peak Series Collapsible Squeeze Bottles and Gravity Systems

My son spent 2 months with the Maasai Tribe learning center in conjunction with Prescott College of AZ. He loved the ease of use and taste, especially with the travel camel bag carrier we purchased. Magnificent and necessary items.

This replacement filter is great and works on the peak perfectly.

Great filter, works super well and fast. This is my second one, bought it as a backup in case I lose the other one.

Live in Alaska and use these on every hunting and fishing trip. Eliminates the need to haul water and this Brand, Life Straw has NEVER failed us. When you are on a Fly Out hunting or fishing trip you don't have to worry about having quality, safe water to drink. We have small 1 ltr for each person and the Mission 5 and 12 ltr systems for camp. Never had a problem. Best money you could ever spend.

It's Lifestraw. They work great. Water tastes better, not full of sediment and plastics. Get em!

These clog so fast and it makes filtering water impossible. It literally took me an hour in the backcountry to get a liter of water! Not a product you want when your life depends on it.

I’ve had the lifestraw for about a week and really liked it the bag form factor is interesting and quite useful (can pack it easily when empty) unfortunately it broke kind of suddenly. There was no abnormal use and I pull it out of my backpack to find the filter just floating and then realized it broke. For something that’s marketed towards camping, hiking, etc. I’m really disappointed that it broke while walking around an urban environment.Going to try and fix it with super glue
