Matilda's Own DIY Filter for DIY Face Masks
Using the knowledge gained by making mask filters for the CSIRO in recent trials, Matilda's Own have created this highly efficient face mask filter. Made in Australia from 100% Hollow Conjugated Polyester for moisture absorption and extremely effective particle filtration.
Each pack contains 4 x A4 sheets, measuring 210mm x 297mm for use with your own cotton outer and makes up to 24 refills. Refills are washable but we recommend replacing them after each use.
Pack includes a free downloadable pattern, or search the internet for free face mask patterns in your preferred style.
