Clean your bottle or water container thoroughly before filling with water and using a StayPure capsule for the first time.

When using a capsule for the first time, rinse the capsule itself under the cold tap before placing it in the water container. When placing the capsule into the container, allow it to sink to the bottom. Occasionally shaking the container improves the performance of StayPure capsule.

The capsule should remain immersed in water for optimal performance. Your bottle or container can be topped up with fresh drinking water regularly without any need to empty the water already there.
