Good, small portable water filter
I was looking for a decent, small water filter to use at out off grid cabin to filter the spring water. Thus worked out great. A bit big for backpacking. A little costly to use but nearly as bad as some others. Nice size that can be easily stored in a draw. Easy to setup, use and take down. Flows reasonable well so it doesn't take all day to filter a gallon of water. We do run the output of this into qallon, glass containers and add a drop of chlorine, then wait 24 hours to use. But our area has Guardia and some other 'nasty' things which is why we bought this!

Clean water at a great price!
Absolutely amazing system. Couldn't be happier. Not only is it lightweight, it filters relatively fast,and taste great. My last few trips backpacking, I was able to provide clean water to the groups of friends I was with. Doesn't leak, material is durable, and has a compact size. Well worth the money.

Good with adjustments
I love the concept of this but not the functionality. The clamp on the hose did not work well, it kept leaking so I had to keep the spout above the bag to keep from losing water.

Love this product. I recently bought it for my backcountry camping in Algonquin. Super easy to use, water comes out tasting just like water - no weird taste or chemical taste. I highly recommend. The only thing I wish it has was another bag to store the fresh clean water. Hard to only have the water come out as is instead of leave it to filter in a bag ready to drink. It comes with a little water bottle but it only attached to the filter. I ended up buying a water storage bag with a spout and it was perfect

I am taking this on a fishing trip up north and will use the lake water for drinking. I used it once with well water we are not " supposed " to drink . Water was good to drink otherwise I wouldn't be writing this.

Filters water perfectly, it taste great too depending on where you filter it. sometimes its hard to fill the bag depending on what kind of water source you can find. All in all, really good, wish the clamp worked a little better to hold the water in the bag.

Just received this water filter in about five days. It looks sturdy and good quality on opening the box, but haven't used it yet. I plan to keep it handy for emergency use only but it looks like it would be excellent for camping, hiking or survival use. I'll keep mine next to my big jugs of emergency water supply just in case. I can also quickly pack it into my car if I ever have to evacuate my home and can use it to keep hydrated from most water sources like lakes, rivers, streams, ponds etc. It can be used alone as a straw, or as gravity fed from the water bag provided, whatever the circumstances demand. All in all a good purchase in my opinion.
