Gravity Water Purifier, Water Filtration System with 3L Gravity Bag and 0.01 Micron Straw Filter, Versatile Use, for Hiking, Camping and Outdoor Activities.

I am an outdoor enthusiast, and I accidentally bought a portable filter from this new brand before. The quality is very good, and I like it very much, so I followed this brand. This time I tried their new product, and it was pretty good overall.

This is a pretty good product that compares well to similar products. I don't really use the "gravity" method as it's too slow and cumbersome. It would be fine if you need to put the water into another container to, for example, put a flavor/electrolyte packet into the clean water. Twisting the filter straight onto a bottle drinking from it is the easiest way in my opinion just for straight clean water. That's what I did most of the time testing it and it worked well.This is a good product and well made. It's not any better or worse than similar style water filter products. It would use it again.
