Make your mask safer with HELIX.iso+™ drop-in filters.
- HELIX.iso+™ filters are compatible with most cloth masks that accommodate a replaceable filter and can be cut to shape. It is recommended to replace the filter as often as possible and should be disposed of safely.
- Offers Level 2 (highest) performance under the new ASTM F3502-21 standard for Barrier Face Coverings, meaning easier breathing and greater protection.
- Uses wool-based HELIX™ Filter Technology for greatest breathability. Any organic markings are harmless and are proof of the filter’s natural origin.
- Proudly made in New Zealand by Lanaco.
