## Features

- 5 STAGE EFFICIENT FILTRATION By using high-quality activated carbon from coconut shells, 0.1µm ultrafiltration membrane and other selected materials, the water filtration system can effectively reduce harmful substances such as chlorine, particles, sediment, stones, sand, dirt, as well as bad taste and odor. So it ensures safe water and a better drinking experience.
- LONGER LIFE The Waterdrop filter system delivers up to 5,300 litres of safe drinking water and ensures a maximum flow rate of up to 700ml/min to allow for a relaxed drinking experience outdoors.
- Reusable filter: thanks to the innovative backwash function, the interior of the water filter system always stays clean. It is reusable, safe and environmentally friendly. If the water flow decreases or the filter has been used for a long time, you can remove the mouthpiece and rinse it with clean water. (A standard water bag can be used, or a plastic bottle with a thread diameter of 27.5 mm can be filled with clean water to clean the filter by backwashing. ).
- Versatile Applications The water filtration system can be connected to water bags or bottles to filter water for drinking. Both ends can be disassembled and connected to water bags or bottles to provide clean drinking water anytime and anywhere.
- Outdoor water requirements: meets all your outdoor water supply requirements: hiking, camping, travelling at home and abroad as well as emergency preparedness (tornadoes, rain storms, earthquakes, floods, etc.) to meet the water needs in various situations in an emergency. Each filter weighs only 86g.
- Note: Before first use, please remove the cap and immerse the filter system in clean water for 10 seconds to prepare it. This makes the internal ultrafiltration membrane wet and water can be filtered more easily. Depending on the water quality in your region, you should rinse the filter system regularly with clean, fresh water. This extends the service life and prevents blockages.

**Q: how long does this product last? 1 day? 1 month?**
A: I  used it for the first time this weekend. On a backpacking trip. I thought it was useful to have in addition to a filter pump to bring water back to Camp. It seemed well-made, how long it will last Would probably depend on how dirty the water is that you put through it ,if you clean it consistently and if you were careful not to abuse it. But I will get $20 worth of use out of it for sure.  I expect it to last me for multiple trips.

**Q: Does it come with the bag?**
A: Hi Mike,

Thank you for your interest in our Water Filter Straw. Yes, the item comes with two bags.  One is the blue gravity water bag which is used to fill with the raw water, another is white used to fill with the filtered water. They are connected via the straw to filter the water for drinking.
