SimPure Gravity Water Filter, Portable Gravity-Fed Water Purifier with 3L Bag, Tree Strap, BPA Free Survival Gear and Equipment for Camping Hiking Emergency Preparedness

The water filter works great. It hold plenty of water for multiple people to be able to use although it isn’t huge. It packs down small and doesn’t weigh much. I was fine when I used the filter provided, however I did decide to get and inline sawyer filter for peace of mind.

I used this filtering system on one trip and it worked as expected. Filtered and enjoyed lake water on a 4-day trip to boundary water with no issues. It takes about five to 8 minutes to filter three gallons. Performed a little test on the last day of the trip by drinking a cup of unfiltered water and got sick for a few days. It works lol. haven't checked to see if replacement filter is available.

Compact and nice addition to have while hiking or camping.Happy with purchase

This is a must-have for camping. The capacity is enough for a couple of people without having to constantly refill it. It's easy to use, and the water tasted great. It worked so well that I bought a few extra to donate to those impacted during the 2024 hurricanes.

I live off grid so this filter is great for my needs. It does take about 30 minutes to fill a gallon container, but I can do other things while it's doing the job. I filter roof rain run off (containing dirt/ fire ash/ chem trails) and it's clear when it comes out. If the filter sits too long I do have to clear the inlet by smacking it against my hand once in a while. Overall, for me, this filter is exactly what I needed

Keeping this in our emergency kit, I have not used it but it’s reassuring to know that I can filter water if needed.

This is constructed very well, I have not taken it in to a major trail for days on end but have done a good bit of testing and using it around the yard and have not had any problems, it takes most personal filters with no problem, I also try to keep two or three empty bottles to fill with this.

We saw this on the Wooded Beardsman's YouTube channel, and had to get one to treat the water at our hunting camp. Our camp's water comes out of the ground into a collector, then it overflows into a reservoir, before traveling by pipe into the camp. The water should be pure, but you never know if something may have died where the water supplies the spring or even in the reservoir or collector.We hang the bag on a nail and let it drip into our 7 gallon water cube, and let gravity do all the work. It is slow going, and I've heard that pressing the bag will help it move faster, but we just let it do its own thing on its own time. The bag has a handle that slides on and off for filling and hanging.The most important thing to remember is to get all the air bubbles out of the tube, so the water flows well. Tapping and squeezing the tube will remove the air, and then gravity does the rest. There is no taste issue, and the water is completely clear. A must for anyone with the time to purify water.
