Face Masks

£4.00

IMPORTANT
These face masks do not replace N95’s for health professionals. Wearing one of these masks however, means we can save the N95’s for the frontline workers who need them. These masks will fit over N95’s.

A Cambridge University Study from 2013 * tested the effectiveness of home made masks.
The study found that 2 layers of tightly woven cotton fabric would EACH capture 61-69% of 1-micron particles , which is smaller than produced when we cough or sneeze, providing good breathability and effective protection.

3 layers increases effectiveness by to 74% – added filtration such as 2 layers of blue shop roll increases this to up to 93% of particles as small as 0.3microns. Paper towels can be used but are not as effective as the blue roll. The more layers the poorer breathability but greater protection.

When choosing a 2 or 3 layer mask you should weigh up the length of time you will be wearing it, against breathability. The 3 layers can be work as is or with an addition 4th filter layer added.

Available in 4 sizes: XS – Toddlers, S – School age children, M – Womens, L – Mens can be purchased with or without filter packs (3 layer only) Please get in touch if you have a fabric request or would like to see a sample of the fabrics listed.
