Some filters or strategies solely take care of micro organism and protozoa, while others could solely do viruses.

The outdated triad of value vs. bulk vs. weight is at all times going to be a balancing act for us folks who like to hold all the pieces on our backs. If you happen to’re a car-camper, day-hiker or slush-fund-recipient, then a few of these choices received’t be as essential.
