The HELIX.iso™ is a New Zealand made Wool Fibre Filters are designed to work in conjunction with the BONZ MerinoShield knitted face mask. HELIX.iso™ Filter Media traps the smallest of particles and bacteria and allows people to breathe purified air in a polluted environment. Chosen by NASA for their next mission to the Moon, the filters performance is driven by specially formulated wool fibres from a composite sheep breed called the Astino.


Wool doesn’t burn readily, and HELIX™ Filter Technology captures invisible particles and locks them inside the matrix just like a dust magnet. The wool fibre also has an amazing propensity to manage moisture. It can absorb 30 per cent of its own weight in moisture before it feels wet; synthetics are less than 10 per cent.
