I think most people use some kind of filter. Mine is an MSR pump kind of deal about the size of a soda can. It’s a few years old and a little heavy but these things get expensive and it’s hard to keep up with it smaller and lighter technology.
The little dissolvable tablets are a pain in the neck because they take a long time. And there are those hearty few that just dip and drink but I would not attempt that especially in a low snow year.
