(Free water filter giveaways until end of Tuesday the 26th! See post for details.) Review of the best survival filters for preppers I just finished a big 48-hour review of over 70 water treatment products for prepping. When the "what filter should I buy?" question comes up again and again, the usual answers are Sawyer Mini or Squeeze (or even LifeStraw, which we never recommend). But in the end we picked a Mini competitor, the relatively new HydroBlu Versa, as the best singular pick. Other models we like: Pumps: Katadyn Hiker Pro and MSR Guardian Bottles: LifeStraw Go, Aquamira Frontier Flow, Sagan Journey, and LifeSaver Liberty Gravity: HydroBlu Go Flow Straws: Survivor Filter, HydroBlu Sidekick (EDC) In the end, which filter makes sense for you depends on a variety of factors. But the right answer is usually a mix of 2-3 different models and types to cover all your bases. Personally, in one bug out bag I run a LifeStraw Go bottle with spare filter, HydroBlu Versa kit (with bags), and Katadyn Pocket. In another bag I plan on running a HydroBlu Go Flow gravity kit (with their inline filter), LifeSaver Legacy bottle, and Survivor Filter straw. What do you like, and have you compared it against others or just in a vacuum? Happy to answer any questions about filters, alternatives, water threats, or whatever!
