THE BIG QUESTION IS: Water FILTRATION or Water PURIFICATION?
Do I need a Water FILTER or a Water PURIFIER ?
YOU HAVE TWO EXCELLENT CHOICES DEPENDING ON YOUR NEED!
CHOICE #1 If you are only using treated water, tap or bottled, then you only need the Sawyer Biological Water FILTER to further filter your tap or bottled water. This filter removes 99.99999% of Bacteria and 99.9999% of Protozoa and Cysts. (DRP item 690-SP180)
CHOICE #2. If you will be drinking wilderness water (lakes, streams, or ponds) in addition to tap or bottled water, we recommend the Sawyer Viral Water PURIFIER . This filter/PURIFIER removes 99.99999% of Bacteria, 99.9999% of Protozoa and Cysts, and 99.997% of Viruses. (DRP item 691-SP190)
