Welcome Stephen!
I've had a lot of success by using a simple coffee filter and rubber band around the float inlet. It seems to cut down on the clean up of the cartridge.
I also use a Steripen after filtering the water to help kill any virus that may have slipped through. I don't know if it's overkill or not, but I haven't gotten sick from any of the suspect water that I've poured down my gullet.
If you haven't purchased one yet, you might want to purchase a maintenance kit for the Miniworks. It's pulled my bacon out of the fire more than once when an O-ring goes bad out on the hike.
Hope to see you on the trail.
Thanks boom,
I have been looking around for these repair kits as they do seem like a good investment. Hard to find little suckers though. Either sold out or the store wants an arm and a leg for them. I may solve the o-ring problem by hitting up the nearest Canadian tire and raiding the garden hose isle. See if any sizes match.
Awesome avatar pic BTW.
