The original and only filter straw cap for Klean Kanteen and HydroFlask, the Aquagear Tap Water Filter Straw Cap is the key to on-the-go hydration, giving you access to safe, healthy, and great tasting water everywhere. Simply unthread the cap of your bottle and replace it with the straw cap and start enjoying clean water. This multi-patented product has been thoroughly tested in laboratories around the world for contaminant reduction, most recently by the Los Angeles County Agricultural Commissioner. These tests have proven that the Aquagear tap water filter is the industry leader when removing harmful contaminants commonly found in municipal tap water like chlorine (99.99%), lead (97.5%), fluoride (90%), mercury (99.6%), trihalomethanes (99.99%) DDT (98.8%), Chromium-6 (99.87%). These contaminants have all been linked to diseases and illnesses and DO NOT belong in the water you drink! Aquagear's patented filter meets and exceeds NSF Standards 42 and 53 as well as EPA/ANSI certification protocols.
