The current government advice states that medical-grade masks should continue to be reserved for those who need them to protect against risks in their workplace, such as health and care workers, and those in industrial settings, like those exposed to dust hazards.

N95 masks fall under this category and you really don’t need one unless you are coming into regular close contact with people who have been diagnosed with COVID-19.

What is a face mask filter?

Face mask filters are used as an extra layer of protection to filter out particulate in the air. They usually sit in between the two outer layers of the mask. Several types of face mask filters exist, from basic cloth pieces to carbon filters and HEPA (high-efficiency particulate air) filters.

How often should I change my face mask filter?

There are several great reusable, washable non-medical face coverings on the market that come with removable filters. You should replace the filter regularly – ideally after each use – and wash your mask daily, waiting until it is completely dry before you put it on again.

For filters to work effectively, the mask should fit snugly to your face, with no gaps where air can escape.
