Best Filter For Large Groups!

Great filter if you need a lot of water. Like a troop setting.

Pure Water Less Effort

Absolute Best Gravity System In The Market

If budget is no object - then this is the filter to buy. I also have the Sawyer Gravity system which costs 4x cheaper. Not just a mere filter, it is a also purifier - and the carbon filter is the icing on the cake and makes the filtered water pleasant tasting. Everything about the package is pure premium. MSR did not skimp on the components and it looks and feel as expensive as it actually is. Operating is easy. Long term storage is a bit tedious - it is a 1 hour procedure - but I don't mind doing to ensure tip top performance and longevity. I know some complain about the flow rate. I never measured - I mean between the claimed 2 mins to reputedly slower 2m30secs in the field .. it is rather irrelevant to me for my use. Which is base camp use where I wont be moving for days. Part of enjoying the outdoors is the being calm about everything and 10L filtered water that comes about a few mins late, is a non-issue for me. And it is really great to produce so much filtered water for camp use effortlessly AND it is supercomforting to know that it is (if the claims are to be believed) the only filter to meet military grade specifications. That seems overkill for me but then why not! Downsides : long term storage and PRICE. This filter is insanely priced.

Awesome System

It's just a great and reliable system. Even my kids can use it. We are a family of 5 who go camping with friends and we need a lot of water often we use 70 liters on a weekend. With the gravity system we never run out of water and the system does not require attention so it's very good for camping with small kids.
