Reusable Polypropylene Filter


3-layer masks with a polypropylene filters are now recommended by Canada's Chief Public Health Officer Dr. Theresa Tam.

  • The Public Health Agency of Canada is now recommending Canadians choose three-layer non-medical masks with a filter layer to prevent the spread of COVID-19 as they prepare to spend more time indoors over the winter.
  • "To improve the level of protection that can be provided by non-medical masks or face coverings, we are recommending that you consider a three-layer nonmedical mask," she said.
  • According to recently updated guidelines, two layers of the mask should be made of a tightly woven fabric, such as cotton or linen, and the middle layer should be a filter-type fabric, such as non-woven polypropylene fabric.


Our polypropylene filters are:

  • Reusable
  • Designed to fit our masks and provide maximum coverage
  • Come in 4 sizes (Adult Large, Adult Medium/Small, Child Large, Child Medium/Small)
  • Have markings as visual aids to help ensure that the filter is inserted for best effectiveness


How they help and how to use them:

  • Polypropylene has an electrostatic property which helps to repel viruses.
  • When polypropylene is washed, it loses this electrostatic property.
  • After washing, the electrostatic property can be reactivated by ironing on a low-heat setting or rubbing against something like a rubber glove.
  • The reactivated filter can then be reinserted into the mask.
