Platypus GravityWorks Water Filter

by Christian

Great post about the Platypus GravityWorks Water Filter by Philip at Sectionhiker:

Once everything is connected, put the clean bag below the dirty bag and let the filtering begin. Once there are few inches of water in the clean bag, it’s important to lift it above the dirty bag, so that any air bubbles in the hose or filter element can bubble up and back into the dirty bag. This also serves to backflush the filter and prevent clogging. Once the bubbles stop, lower the clean reservoir and let the filtering complete.


It is so easy to backflush the filter this way, it makes sense to do it each time, thus reducing the risk of clogging the filter out in the field. 

I agree, the filter is ideal for two or more, a bit overkill for just a single hiker, but even then, I prefer this setup over a pump filter anytime. I've replaced the MSR Miniworks with this Platypus Gravity filter and don't look back–no more pumping! Also, and this might just be the Miniworks, I was fed up with the Miniworks constantly clogging up when the water was less than crystal clear. Philip is right, that it is a bit bulky, but since it is still reasonably light and filters fast, I think it is one of the better solutions out there.
