CleanStream Gravity Filter

Using revolutionary Hollow Fiber technology and a little physics, the CleanStream microfilter system treats 4L of water in less than 2.5 minutes—all without a single pump stroke. Need a lot of water? Just refill the Dirty side - even before the Clean side is empty and you’ll be automatically refilling as you go. A quick-disconnect fitting allows for easy removal and filling of the Dirty reservoir and back flushing for optimal performance is as easy as changing the height of the reservoirs. No moving parts, no assembly, near-zero effort. It’s lightweight enough for two, and efficient enough for a whole group. Really—it is that good.
