Review: Essential and excellent accessory - Very flexible and adaptable system, will work in very many different settings or activities. The Tygon tubing is good quality and the fit of all the parts is good. Because of its modular nature, this filtration system is quite compact and lightweight. The price is quite affordable. Per its usual, desertcart will deliver to your doorstep at lightning speed, so overall a very satisfactory purchase.
Review: Impressive and convenient water filtration - We used this bag and filter every day for a week of wilderness camping. I bought a second after being so pleased with this one. Flow rate is superb compared to competitor products. We had one or two days where an algae bloom heavily covered the surface water of the lake. We filtered water all week without problem. Backflushed easily on day 5 with clean water and was amazed to see the amount of algae and dirt that came from the back wash. Restored back to original flow rate. The bag is durable but I could see it getting damaged if not protected or stored properly. The water tasted good for the price point. Compact space saving design.

**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.

### ⭐⭐⭐⭐⭐ Awesome, it works, and gives you a lot of options
*by D***L on August 12, 2025*

This filter is awesome, used it on a three day backpacking trip recently. No issues whatsoever. For everyone’s information however, the reservoir bag does not seal fully when filled. The top, although it folds nicely into a handle for carrying - which is amazing and super convenient - it does not prevent water from coming out the top if you, let’s say, put the bag down on the ground to get the straps adjusted or something. So the reservoir is not for carrying water for long distances, unless you’re prepared to always keep it upright and never put it down until you can hang it. Still super doable if you’re going short distances, it doesn’t spill when you’re holding it by the handle, just if you put it down on the ground while filled and it falls over. Other than that, this kit is awesome. Gives you the option of reversing the steps, instead of filtering the water into the small plastic water bottle pouch, you fill the plastic bag with the unfiltered water, screw the filter straw onto the pouch, and drink it directly out of the filter (basically a life straw). I think the bag might be half a liter that it comes with, so if you want a bigger pouch then you’ll have to order one. This is the way I’ve seen most through hikers using it, usually with the sawyer filter setup. But this filter gives you both options, filter the clean water from the reservoir into the plastic flexi pouch or any other bottles you want, or collect the unfiltered water into the flexi pouch, attach the filter directly to the pouch, and drink through the filter. Super lightweight, condenses into a really small volume, durable (I carried water in the reservoir for more than 5 miles, by hand, leaning it against a tree when I had to put it down, and the material held up). We used it for three days and that was more than two weeks ago, long enough for any water born sicknesses to have shown if it didn’t work. Great purchase.
