Sawyer - Sawyer Mini Water Filter. The popular Sawyer Water Filter just got smaller and lighter. The Sawyer Mini Water Filter weighs just 2 ounces and filters up to 100,000 gallons! What’s special about Sawyer filters is they filter to 0.1 micron absolute, exceeding EPA and NSF recommendations. Did we mention you can drink directly from the Mini, attach it to Sawyer Squeeze Pouches, use inline on a hydration pack, or attach it to the top of almost any bottled water? How about that for versatility?
