Drop-in Helix.iso™ Filter

What is the HELIX.iso™ Community Mask System

Lanaco is joining with community sewing groups across New Zealand to supply an open source mask design that can be locally produced and fitted with high-performance HELIX.iso™ filters for enhanced protection. We believe the community mask system will help support communities with employment, access to masks and create positive feelings of self-help.

We have provided an open-source mask body pattern designed by HK Mask, which you can download to use when making your masks.

The mask is designed to fit our special HELIX.iso™ and HELIX.iso+™ filters, which you can easily remove to replace when needed, the mask body (outer layers) can be re-used and washed regularly. All contaminated filter elements must be disposed of safely and should not be re-used or washed.

When correctly fitted, your mask containing a HELIX.iso™ or HELIX.iso+™ filters filter will provide excellent protection and comfort to enable prolonged use.

HELIX.iso™ is 50gsm and the HELIX.iso+™ (plus) is 100gsm.

This is not an N95 mask. N95 refers to a safety standard for industrial use.  (N95 is an INDUSTRIAL standard for adults in the workplace).
