Our Face Masks are made with a slot to be able to insert a filter and we recommend this for greater protection. 

This pack includes 7 replacement filter elements that can be easily cut to size to fit most masks.

HELIX.iso™ filters are made from natural NZ wool fibre for enhanced protection and may contain organic markings. Any organic markings are harmless and are proof of the filter’s natural origin. They do not affect the performance of the filter.

We recommend that the filter should be replaced as often as possible depending on how much use the mask has. All contaminated filter elements must be disposed of safely when replaced and should not be re-used.
