A water bottle with an integrated filter is a great hydration option for day trips or any situation where you want travel light. The Platypus Meta is cleverly designed: The bottle can be used with or without an internal microfilter that removes bacteria and protozoa, such as giardia and cryptosporidium. The soft-sided bottle drives H2O through the filter cartridge and doesn't taint water with plastic taste. Keeping the filter clean to maintain a good flow rate is as simple as shaking the bottle (though it's a good idea to scoop from a clear, silt-free water source).
