Designed to provide optimum performance & protection. The unique Waire™ Respirator Mask incorporates the HELIX™ smart, natural, science-based wool formula to provide optimum performance and protection.  This unique mask features 55% wool content. Natural wool fibre has amazing capabilities which synthetics can't match. Wool is the world's most positively-charged fibre, which translates to an electrostatic filter which acts as a magnet to capture a whole range of particles in the air. The Waire™ face masks also have low breathing resistance making them easier to breathe through. Waire™ masks are designed and manufactured to offer AS/NZS1716: P2 / N95* level protection when fitted and used correctly.
