Before first use, fill the bottle to submerge the filter for 15 minutes. That’s it. You are good to go. If used regularly, the filter only needs to be activated once. You do not need to activate the filter every time you use the bottle. If your filter dries out completely (usually because it has not been used for several weeks), just reactivate and your bottle will be ready for use.
Just sip or suck gently to draw water through our powerful multi-layer filter. The water will flow more slowly than you might expect because the filter is removing harmful contaminants that other bottles can’t handle.
In general, you can fill up the bottle at a tap 2-3 times a day and the filter will last for 3 months.
Filters 200 liters/53 gallons depending on use. For example, if you are filtering water with heavy silt or sediment, filter life will decrease.
After three months of cumulative use we recommend replacing your filter. If you are traveling to a part of the world where the water is particularly unsafe we recommend changing the filter every two months.
Have fun and stay safe.
