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.
