Just the FAQs
How does the LARQ Bottle PureVis™ 2 hydration tracking system work?
The cap has a built-in sensor for hydration tracking. After filling the bottle and screwing on the cap, place the bottle on a flat table. The cap will glow a white light indicating that a measurement has been taken; this can take up to 5 seconds after placing it on the table.Hydration tracking works best with cold or room-temperature liquids. Hot liquids will fog up the sensors and tracking will not be accurate.
How often does the Bottle Filter need to be replaced?
The bottle filter should be replaced every 40 gallons (151 liters) or about 2 months.
Can I use the LARQ Bottle PureVis™ 2 in the backcountry?
Yes! For use in the backcountry, first, take out the Filter Straw and use PureVis™ Adventure Mode (double-click) on its own. Then, put the Filter Straw back in. Finally, fill with water that is clear to the eyes with no sediments.As a rule of thumb in the backcountry or on hikes, stick to running water sources such as rivers, streams, or waterfalls, further away from vegetation.
What contaminants will the filter remove?
