The UK recommends the use of FFP3 respirators when caring for patients in areas where high risk aerosol generating procedures (AGPs) are being performed. When FFP3 respirators are not available, then FFP2 respirators may be used.
The World Health Organization(WHO) recommends FFP2 and N95 respirators for AGPs and these are widely used in other countries. The N95 respirator is not CE marked but has been tested against standards similar to European standards.
