Face masks (particle filtering half masks) are worn by adults and children from the age of seven in the context of the current coronavirus pandemic, both in public areas and indoors, voluntarily or according to law.
They protect against the inhalation of the viruses as well as airborne allergens; this includes cat allergens.
According to the international literature (as at 27 February 2022), standardised tests have been conducted on the FFP2 mask and surgical masks in terms of their protective effect in adults with grass pollen allergies. However, given the properties of the two masks, it can be inferred that they are also suitable for protection against cat allergens, with the FFP2 mask being advantageous.
