FAQ

As a general guide, we recommend replacing your MEO filter every 2-3 weeks. For the MEO Lite and Kids filter, we suggest replacing every 50 hours of usage, or 10 days if used daily. For pollution protection, these recommendations are based upon an Air Quality Index (AQI) of between100-150.

Our Helix™ filters are made of natural wool fibre. Wool fibre is comprised of a protein called keratin, which is the same protein as human hair. Wool will decompose when left in damp environments, such as soil, for a prolonged period of time.

You can wash the mask cover, but not the filter.
The mask filters are designed to be disposable, and should not be washed. This wool has natural electrostatic properties, which will be damaged when in contact with water.

You can wash the mask cover when you replace the filter. The mask cover can be hand-washed in warm water with gentle soap, and left to dry naturally.

It is recommended you store the mask away from moisture, heat, and sunlight; in a cool and dry place.
