Moosejaw Staff Pick
"I have had the MSR Miniworks EX Microfilter for almost 10 years now and it has never failed me. Sure, there are faster filters now, but this guy will simply not let you down because it's really easy to use and field maintain. Just screw your large mouth bottle on the bottom of the filter, throw your hose in the water, and then pump away. The ceramic cartridge is super durable, as well as the housing. I have dropped it a lot and never had anything break on it. The carbon core filter actually flavor corrects the water too, so you don't have strong mineral tastes, and you can even pair the MSR Miniworks EX up with any tab you would use to kill viruses. Use the tab, then filter that water through this and it will be virus, bacteria, and grit free, but still taste fresh. A great piece of reliable gear."
