## Description

desertcart.com : Waterdrop Gravity Water Filter Straw, Camping Water Filtration System, Water Purifier Survival for Travel, Backpacking and Emergency Preparedness, 1.5 gal Bag, 0.1 Micron, Light Blue : Sports & Outdoors

Review: Good, small portable water filter - I was looking for a decent, small water filter to use at out off grid cabin to filter the spring water. Thus worked out great. A bit big for backpacking. A little costly to use but nearly as bad as some others. Nice size that can be easily stored in a draw. Easy to setup, use and take down. Flows reasonable well so it doesn't take all day to filter a gallon of water. We do run the output of this into qallon, glass containers and add a drop of chlorine, then wait 24 hours to use. But our area has Guardia and some other 'nasty' things which is why we bought this!
Review: Highly recommend.Fresh water - Good quality, price ,will work,during next bicycle tour, work doesn't taste very good in different places don't have to buy good water now,takes all of the bad stuff out of water

## Features

- Multistage filtration: With adoption of 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.
- Professional Combination: Waterdrop Gravity Water Filter Straw with 1.5 gal Gravity-Fed Water Bag is an exclusive water purification combination created for outdoor activities and first aid survival. The large-capacity water bag can hold up to 1.5 Gallons of water at a time, which is about 11 bottles of 500 ml bottled purified water, and can meet the all-day demand for outdoor water drinking.
- 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.
- Warm Prompt: If the gravity bag is used to filter water, turn on the drainage valve first to empty air from the hose before connecting with the straw to avoid no water flow in a vacuum state.
- Multi-scene Application: As a necessity for outdoor water purification, the Waterdrop Gravity Water Filter Straw is applicable to hiking, camping, domestic and international travel, emergency preparedness (tornadoes, rainstorms, earthquakes, floods, etc.) to meet the emergency water demand in a variety of situations.

### ⭐⭐⭐⭐⭐ Clean water at a great price!
*by J***O on August 24, 2025*

Absolutely amazing system. Couldn't be happier. Not only is it lightweight, it filters relatively fast,and taste great. My last few trips backpacking, I was able to provide clean water to the groups of friends I was with. Doesn't leak, material is durable, and has a compact size. Well worth the money.
