HeiQ Viroblock is added to fabric during the final stage of the manufacturing process. It uses a unique combination of silver and vesicle technologies in a dual defence against dangerous pathogens :

  1. The HeiQ vesicle technology – many viruses are coated by a lipid (fatty) membrane that protects them. HeiQ vesicle technology targets the membrane surrounding the virus. This exposes the virus, deactivating and making it useless within minutes. 
  2. HeiQ silver technology – inhibits the replication of bacteria and deactivates viruses.

Standard face masks can be a dangerous surface for viruses and bacteria. When you touch the face mask (pick it up, take it off or adjust it on your face) there is a risk of transferring pathogens. Due to the self sanitising nature of the anti-bacterial treatment on the fabric, AVIRO reusable face masks need not be washed daily. We recommend washing after approximately 20 hours of use or if it gets visibly dirty. Wash in gentle wash in laundry bag in 30℃ and below. Light detergent & no fabric softener. Not intended for medical use. *Identification of Viral Strains: Influenza H1N1 ATCC VR-1683, Coronavirus (Feline), Strain Munich. *antimicrobial activity slowly reduces from 99.69% to 99.29% after x15 washes.
