MSR Guardian vs APEC Water Systems WFS-1000

The MSR Guardian is an exemplary product and one of the very best Backpacking Water Filters at the $390 budget.

The APEC Water Systems WFS-1000, however, doesn't seem to have enough data available for us to be able to draw any meaningful conclusions. If you're considering Backpacking Water Filters in the $130 range, you might want to check out some other options.
