  • 4 trips & it works fine
I've taken it on 4 trips & it works fine. Filling it is a little tricky. The flow is usually a fast drip, not a steady stream. I fill it, hang it, and leave it to do other tasks. I found it's important to clear the water line of bubbles to get a good flow. Also, you will need to clean it well and dry it after each trip. ... show more

  • Easy assembly, quick filtering action
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. ... show more

  • No moving parts to break.
This is the best system I have ever used. No pumping needed; just gravity.

  • Good filter kit for camping or bug-out bags!
Because we ARE +78% water we need to keep topping off the tank... and polluted water WILL NOT do the trick. Which is why we ALL need a SOURCE of fresh clean water. Arrived promptly and in good condition. Saving it for a rainy day if I have to... make sure YOU have access to SAFE drinking water.

  • Product works.
My son's and I just spent 3 days on the Colorado River, in Glen Canyon. We did the back hall services up to the dam and kayaked down through horse shoe bend. We did 14 miles and camped two nights. This little filter provided us all the water we used over the three days we were there, we filter at least 8 different bag fills to meet our needs. It worked great. Will use again and probable purchase a second one for back up for long back woods trips. ... show more

  • Great small and light solution for wilderness activities.
It's nice for motorcycle adventure riding (and probably backpacking) because it packs down really small. It's not a speed filter by any means, but if you need drinking water in the wilderness, you'll wait 10 mins for the filter to do its thing.

  • 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
