PurewellWater Purifier Pump with Replaceable Carbon 0.01 Micron Water Filter, 4 Filter Stages, Portable Outdoor Emergency and Survival Gear - Camping, Hiking, Backpacking

Great packaging and works well.

This is my first time using a pump filter for backpacking. The pump is pretty easy, but does take a bit of work to fill up my 3L water bladder. The clip on the hose helps keep the water flowing into the bag without having to mess with it. The filtration looks good, but I haven't tested it on murky water. Overall, it packs a bit larger and heavier than a Sawyer Squeeze filter, but is light and enough to be a good backpacking option.

I used this on a 30 mile Clarion river overnight kayaking trip. It worked well, but does take a while to produce any significant volume. My biggest gripe is the overall size and weight of the unit. Although not huge, it takes up a good amount of space in a pack, and the hoses are so soft and flexible that they kink constantly and restrict flow, making a slow pump even more aggravating. The cotton pre-filter also clogs up very quickly and had to be constantly smacked against the water to clear out enough to flow. The quality of the water was perfectly clear and had no taste, so the final product was great. Add some more rigid hoses, and wrap a coffee filter around the entire intake nozzle and it should be a lot better. I give it a solid "OK".

As advertised.

I drank water straight from the mountain fresh water creeks when camping. It takes a little time to pump a gallon thru the system but it really works well and durable. I recommend this item.

This was very easy to use & great for the price. I needed some budget-friendly backpacking gear & this performed well - the water came through clear & I didn’t get sick after using it for a few days, so far it works great! Pretty easy to pack back into the bag, too. No need to splurge on a brand name

I live in NYC and the tap water here is pretty good so I’m not concern about drinking straight from the tap. But some days of the month the chlorine level is a little stronger, so I do want to have a water filter for this reason. I had one of those filters with the 3 huge canister filters, the ones that you have to install under-the-counter and drilled a hole through your countertop and refit the plumbing to accept the additional water valve but to my horror those canisters leak every year. I disconnected it after the 2nd leakage and decided to try this camping filter. I was very surprised of the water quality it produced! It’s small so it doesn’t take up too much space and no need for all the strenuous installment routine and I’m worried free of any leakages. I wish I had discovered this before I met the first water filter disaster.

We used it for a 3 day backpacking trip, filtering a total of somewhere around 30L of water. The filter worked fine in terms of filtering performance. The water tasted fine and nobody got sick. But 3 things stand out: 1) the part that goes underwater won't stay there. It likes to float up and suck air. You need three hands to operate this thing. 2) the hoses are too short - making it more difficult to operate, particularly in moving water, 3) after about 6L of filtering it got really slow. The last few liters were torture. We were filtering very clear water, so I don't think it should have been clogging. I tried to figure out some sort of backflushing method but could not. I did figure out how to get a massive arm workout, for every liter pumped. I think it took about 150 pumps to filter 2.5L. Every pump was a workout. Imagine filling 4 peoples' water bladders! BEWARE if you will depend on this thing for water for several people or several days.
