Offering a high level of protection when worn correctly, this comfortable mask is made from two layers of organic cotton. A flexible nose bridge can be moulded to ensure a good fit and toggles can be adjusted to ensure elastic ear loops fit well.

Designed to use in conjunction with HELIX.iso™ Filters (two included). These can also can be purchased separately. The exceptional electrostatic capabilities of HELIX.iso™ Filters capture the tiniest dangerous airborne particles. This same best-in-class technology has been scientifically developed for industrial, medical and respiratory health sectors and has been chosen by NASA for critical life support in the next manned exploration to the moon. Using one filter insert will capture more than 80% of particles 3 micron and larger. Protection levels increase to 95% with the use of two filters.

The HELIX.iso™ Filter matrix has extremely low breathing resistance, making it exceptionally easy to breathe through. Long term this Adjustable Helix Mask can be used to protect you from pollutants when you’re gardening or commuting by bike or on foot.

Please note: This is not an N95 mask or a respirator and is designed for general public use, not for use in a medical situation. We cannot guarantee wearing this mask will eliminate the risk of infection or contracting a disease.

*The test reports are for H100s, which is Helix.iso+ (Thus Helix.iso standard are H50s, and when two are used will perform the similar to H100 but has not been independently verified)

• The Helix.iso+ filters have superior performance to so called surgical or medical masks.
• When tested to standards for medical masks (ASTM F2299) they outperform medical masks by providing very high protection (99.6%) but with lower resistance.
• When tested to medical mask standard EN14683:2019 and ASTM F2109-19, they provide superior protection (99.8%) at lower resistance.
• When tested to N95 levels according to ASTM F3502-21 (a test which is significantly more rigorous than the medical mask, they provide protection to near N95 level - 85% not 95%, at significantly lower resistance).
