slow but great filter
5 out of 5 stars
slow but great filter
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

    The portable water filter was perfect for my hiking trip. Small and lightweight enough to easily carry around. While on my hike I was able to get the water directly out of the river to drink or store in the water bag. I can even filter water out of a bottle due to the extension tube that can connect to a water bottle. The tube is a water filter that removes contaminates that can affect the water such as rocks, leaves, chlorine and mercury just to name a few. The removal rate is up to 99.99999. What a life saver it turned out to be on my hike.

    3.0 out of 5 stars UPDATE!!!...GOOD CUSTOMER SERVICE RESPONSE...PROBLEMS PERSIST
    Reviewed in the United States on May 19, 2022
    Verified Purchase
    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.
