How to use

1. Fill

Fill your bottle from any fresh water source. (To prolong the filter life find water with the least amount of sediment)

2. Screw

Screw the filter to the bottle and then the lid to the filter. (Make sure its tight to avoid leakage)

3. Squeeze

Just squeeze the bottle to drink. (Will require more effort than drinking without a filter)


Please read our FAQs page to find out more.

Can it filter salt water?

No, our filters only work with fresh water

How do I know if the filter needs to be replaced?

The filter needs to be replaced once the flow rate has become significantly reduced

What is the lifespan of the filter?

The filter has an average lifespan of 150 Liters (this can vary with the quality of the water)

Does this only work with Specialized Purist bottles

Yes, the threads were designed to be compatible with purist bottles. But if you find a bottle with the same threads it will work

Can you use drink mix?

No, drink mix will clog the filter rendering it unusable. The best workaround is to use one bottle with a filter and use it to fill another filter-less bottle that has drink mix.
