    • Very happy with this filter
Purchased and been using since the summer of 2024. We have found it great for backpacking. Simple and so far still reliable. Main thing to remember is that it's difficult to get going with water / bubbles in the line and filter. Once you can get those out it's a strong steady fast drip to a trickle. We liked the water clarity and taste of our water compared to our friends filtration device by far. Next time I'll take an empty gallon jug of water to drip into while doing other things and just let gravity do it's work. Just used it again 7/25/26 and no changes in my opinion. ... show more

    • Great Product
Mechanically speaking, the filter was terrific. As far as the filtering of microorganisms, it's hard to know unless you were to use a test kit. I drank river water for 4 days and never had any ill effects. So I guess it worked great!

    • Good filter, capacity less than advertised
Bought this for a three day backpacking trip, I had used squeeze filters previously which were annoying to use to filter water for a group. This gravity filter worked well, had a very respectable flow rate compared to a friend's name brand filter, and I liked the catch tray around the filter input to prevent unfiltered water from running down the hose into my filtered water. My only gripe is that the capacity is not actually 3L of unfiltered water, even with the bag topped completely off, it only holds about 2.25-2.4 L. This shouldn't be disqualifying however, as the flow rate was great, but it was a bit annoying to have to fill a "3L" filter bag twice to fill a 3L hydration bladder ... show more

    • Easy to use. Packs small.
Easy to use. Packs small. Is light. Fills pretty easy. Filters well on my first backpacking trip. After washing, drying is a little difficult, as the bag is slim, so I had to stick something in it to dry properly after my trip.

    • If you go camping, this is a must have
My only regret is, I wish it was a little bit bigger. I highly recommend you pop probably purchased a couple of these because you’ll be going through the water faster than what you think.

    • Water tastes so much better with this!
Very durable, the water filtered threw very fast. We are going to travel with it so we have good drinking water. We use it for filtering city water also.

    • UPDATE!!!...GOOD CUSTOMER SERVICE RESPONSE...PROBLEMS PERSIST
ORIGINAL REWIEW INCLUDED BELOW...UPDATE 6-8-22 What to expect from a cost effective gravity water filter?...This is a different name brand which appears to be manufactured for/or imported by a company called "Membraine Solutions" which also markets products under that name. Having previously purchased one of the "Membrane Solutions" products in the past (which had quality issues), I decided to try another name brand...on the surface, both appear to be of the same quality with a few design/feature differences. My original SimPure filter came broken in the package, and to their credit, was replaced willingly and in a timely fashion by the seller. No big hassle. So, ready to test, right? Not entirely, this time I encountered a "small leak" at the bottom of the "raw water" bag. Not a big deal, patched and resolved with a water toy patch kit. Moving on.... using a irrigation canal water source, I proceed to test this filter, and yes, open water does contain "debris" which will clog the filter in short order, but there is a "flushing" method to "clear" some of the blockage which significantly reduces flow through the filter. With this in mind, I will set up this filter "first thing" when arriving at a camp site to allow an hour or so for it to filter it's capacity. I have not utilized this filter as a "straw" because I am very cautious about water safty, and utilize water "purification" tablets after filtering to lessen the risk of contamination or water born illness. So, in the end, my conclusion is that this filer will work for my inteded use (with precautions) and it comes down to a balanced choice of function, price, weight, and serviceable life compared to other filter options. Consider your personal needs, and be willing to try a few different systems (pumps, straws, advanced filters, gravity flow) to find the solution that works for you. Happy Camping :-) And always be prepared! ORIGINAL REVIEW>>> Well, if you're trying to find a reasonably priced, useable gravity filter for camping / hiking, you may wish to look elsewhere ... wish I could say that I had a chance to try this one, but it came broken in the box ... filler bag intact, but straw filter cracked at cap attachment point, so it just leaked all over the place ... I understand there are mistakes in manufacturing, but they should never make it to the consumer. ... show more
