– Start by removing the filter from the mask.
– Proceed to boil filtered water.
– Once the water reaches the boiling point, immerse it in the water for 5 minutes in order to re-activate the ACF (Active Carbon Fabric).
– Let dry in the sun if possible.
– Place it back in the mask once dry.
– We recommend to re-activate it every 2 weeks (frequent use) to 1 month depending on use.
