I use the Hydrapac inline filter, pretty quick for a squeeze type, just make sure you shake it out after you use it and maybe tuck it in your jacket until you're sure it's dry.
anything with hoses, even the insulated ones is going to be a pain if it gets cold enough, wide mouth nalgene, or better yet wide mouth hydropac flex bottle in an insulated sleeve is the ticket, also helps to flip your container upside down so the lid doesn't freeze as bad, if it's real cold finding flowing water is a bigger problem, melting snow is fuel intensive but sometimes better than walking miles to get water...
