The inserted HELIX.iso™ wool-based filters have been tested by a science technology venture based in Auckland that has spent a decade developing its organic/hybrid HELIX.iso™ Filter Media, based on the science of DNA genetics from specially selected sheep flocks that have been bred in NZ to produce a truly unique and high performing wool fibre optimised for filtration. The HELIX.iso™ filter omit virus-sized particles up to 80% using one layer of filter and higher filtration power if 2-layers were used.
