About Us


Silver-impregnated material on the internal layer is proven to kill 99.9% of bacteria, viruses and fungi. Active against human coronavirus OC43.


Data shows that the fabric is still active after 400 washes, although we recommend changing after 200 washes.


Polyester cotton provides comfort and breathability meaning the masks can be worn for extended periods.


Wearing a mask reduces transmission of aerosols and airborne infectious disease from person to person.

It is a crucial part of a holistic strategy to suppress transmission of viral infections such as COVID-19 and save lives.

Why silver?

Silver has been added to a range of fabrics to improve safety, hygiene and product longevity. 

Every Cloud face coverings have an internal silver ion impregnated layer which is activated by moisture.

Moisture from your breath will maintain activation during use, meaning they can be worn for extended periods.

Not all silver fabrics are the same. Our products are impregnated meaning the silver doesn’t leech out into the environment over time and remains active within the mask.



  • Our products are fully tested in accredited laboratories.
  • Our silver impregnated textile significantly deactivates human Coronavirus strain OC43, under test conditions.
  • Our products have been developed to maximise your safety.
  • We offer additional products to increase protection: pouch, washbag, activator spray and sanitiser.

  • Our products are environmentally friendly: waste is reduced and the silver can be reclaimed from the fabric.
  • Our face coverings are impregnated with silver meaning the silver does not leech into the environment.
