Face Mask Filter

Using the knowledge gained by making mask filters for the CSIRO in recent trials, we have created this highly efficient face mask filter.

100% Made in Australia from Hollow Conjugated Polyester for moisture absorption and extremely effective particle filtration.

Each pack contains

4 x A4 sheets, measuring 210mm × 297mm

for use with your own cotton outer.

Makes up to 24 refills.

Refills are washable but we recommend

replacing them after each use.
