Respirator masks (which means they are made of a fabric designed to filter the air or impurities) are based on a grading system do indicate how much protection they offer.
First up is FFP1, which protects against materials in concentrations up to 4x OEL or 4x APF (assigned protection factor).
Next is FFP2 and these offer more protection than FFP1, at concentrations up to 12x OEL or 10x APF. They are the European equivalent of the N95 respirator masks used in the US and this kind meet the guidance from the World Health Organisation (WHO).
The masks that offer the highest level of protection are FFP3, which protect against materials in concentrations up to 50x OEL or 20x APF. This is substantially higher than FFP1 and they can block both liquid and solid aerosols.
Current NHS guidelines stipulate FFP3 face masks for virus and bacterial infection control when the contagion is spread through coughing and sneezing. They are also often used by healthcare professionals when handling hazardous pharmaceutical chemicals.
