Features

  • 5-Stage Efficient Filtration: With adoption of premium-quality coconut shell activated carbon, 0.1 um ultrafiltration membrane and other raw materials, the Water Filter Straw can effectively reduce harmful substances like chlorine, particulates, sediment, stones, sand, dirt, bad taste &odor in water to ensure the water safety and deliver better drinking experience.
  • Longer Lifespan: The Waterdrop Filter straw can provide safe drinking water up to 1,400 gallons (5,300 liters), and ensures the maximum water flow rate of up to 700 ml/min to provide more relaxed outdoor water drinking experience.
  • Recyclable Straw: With innovative backwash purifier function, the inside of the Water Filter Straw can be kept clean at all times and it is recyclable, safe and pollution-free. If the water flow decreases or the filter has been used for a long time, you can remove the mouthpiece, flush it with clean water. (Standard water bag can be used or pop bottle with thread diameter of 27.5mm can be filled clean water for backwashing the filter straw.)
  • Versatile Uses: The Water Filter Straw can be connected with water bags or water bottles to filter water for drinking. Both ends of it can be disassembled and connected with the water bags and the water bottles to offer you clean drinking water anytime anywhere.
  • Outdoor Water Needs: Fulfill all your outdoor water demands: hiking, camping, domestic and international travel, emergency preparedness (tornadoes, rainstorms, earthquakes, floods, etc.) to meet the emergency water demand in a variety of situations. Each straw only weights 0.19 pounds.
  • Warm Prompt: Upon first use the filter, please uncap and infiltrate the straw in the clean water for 10 seconds to prime the filter. This will help the internal ultrafiltration membrane get wet and water can be filtered more easily. According to your area water quality, regularly backwash the straw with clean fresh water, which can prolong the service life and prevent blockage.

  • Great filter, light weight, and flavor/smell never an issue. Kept us safe and hydrated.
Style: Gravity Water Filter Straw/1
This water filter was awesome easy and light weight to carry on a week long trip with my daughter on Isle Royale. There are only a cpl places on the island to get drinking water off tap, you must have filters to get drinking water when back country. Packed easily into my bag, and allowed us to carry 2, 24 oz “Smart Water” sport bottles ea. Didn’t even touch our Sawyer Mini filters we’d taken as back up. Bag opening is easy to fill and close. Only issue, when bag is rolled closed it was not totally leak proof. Awareness to watch for drips into clean water. The bag/filter when hung, provided full 20 oz bottles in short time, maybe two mins to fill our bottles. Cleaned each day as directed. Remember the bag provided for cleaning! We had no issues at all. Took a little bit of space as it’s a rubber bag with long tube with a filter that is for sure longer than a Sawyer filter. Function and provided fast, clean water with ease. beat any space/weight concerns I had initially. Clean, clear water that had no taste issues at all. Pulled water from Lk. Superior and multiple inland lakes. Never an issue and flavor never a problem. Seemed clearer then the tap from Rock Harbor. Awesome product, for sure recommend. Filters are rather large, note the specs given from manufacture. Just be aware of space it does take up. We had no issues even with carrying Swayer minis as back ups. We never used them. 5 nights, 45 miles wandered. Thanks for keeping us with healthy, clean water. ... show more

  • Great filter
Style: Gravity Water Filter Straw/1
I used this on a 3 day backpacking trip on a lake erie island with no drinking water available other than lake water. This filter worked great the whole time giving us clean clear drinkable water the entire time we were there. The bag also held up nicely with no leaks. The water flow through the filter stayed consistent throughout the entire weekend. I will be using this system on future backpacking trips and I would highly recommend this to anyone else heading out into the wilderness for a few days. ... show more

  • Make sure to test ahead of time!
Style: Gravity Water Filter Straw/1
I bought this for a 6-day backpacking trip through Yosemite. It worked well and filled all four of our water bottles the entire time. It was easy to use, didn’t take too long & was lightweight for traveling. I also really loved the extra pouch that came with it because I was able to clip it on the outside as “just incase” water. However, I had to order this product twice because the first time I ordered it - the seal wasn’t secure and it leaked. i’m really glad I tested it out before hand. Second, the extra water pouch it comes with did rip right where it attached to the clip and ripped the whole bag making it useless. I would recommend this product but handle with care and make sure it’s properly functioning before taking it out. ... show more

  • Works as Described
Style: Gravity Water Filter Straw/1
The water purifier works as described. Filtering the water takes reasonable time. We filtered crystal-clear water from Washington creeks and rivers that tasted great.

  • Easy to setup and use. Lightweight for backpacking
Style: Gravity Water Filter Straw/1
If you have never had a water illness and know what it does to you, always use one of these to make sure. Very lightweight and holds 1.5 gallons. Hang it from a tree for easy flow.

  • Works great!
Style: Gravity Water Filter Straw/1
Not going to lie, when I saw the pre-filtered river water, I was really sketched out. But this filtration bag worked like a charm! Water was clear and tasted great! It did get clogged but we just had to rinse it out and blow through the life straw and that worked like a charm! Very thankful we had this thing-uh-ma-jig. It saved us a ton of room/weight during our canoeing/camping trip! ... show more

  • It's ok, leaks and flavor isn't great
Style: Gravity Water Filter Straw/1
The bag system seemed great, but I had to add some zip ties to keep it from leaking unfiltered water into the container I was filling. I tested this against my old filter and the flavor of the water tased the same as non carbon containing filters that don't claim to make the flavor better. I'll have to keep looking for something to help the flavor of the water I'm generally filtering while canoeing and hiking. ... show more
