HELIX.iso™ Wool Fibre Filters are designed to work in conjunction with our Ecoprotect™ Filter Mask. 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.

The antibacterial and antimicrobial properties of the HELIX.iso™ filters naturally resist and reduce the growth of bacteria and microbes on the fibre surface. The Helix.iso™ Filter matrix has extremely low breathing resistance, making it exceptionally easy to breathe through. 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.

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.

Customer Reviews (4.8 / 5 · 5 reviews)

Joseph R. ★★★★★

I was skeptical about wool fibers for a mask, but these filters fit perfectly and the electrostatic claim seems legit—I've noticed a real difference in air quality during my commute.

Evelyn ★★★★★

Finally, a filter pack that doesn't fog up my glasses within five minutes of walking outside. The wool fibres really do hold their shape and stay breathable even after a full day of wear, which is more than I can say for the disposable ones. I've already ordered a second set for the office.

Abigail G. ★★★★★

I was skeptical about wool filter performance, but these eight filters have noticeably cleaner air after a week of daily use. The electrostatic charge seems to make a real difference in how fresh each breath feels.
