Some important context:

An FFP (filtering facepiece) mask (also called respiratory protection mask or simply respirator) is a type of protective mask certified by the European Union. The EN 149 standard defines three classes of filter efficiency for these masks, namely FFP1, FFP2 and FFP3. [Wikipedia]

FFP masks must have a CE mark printed on them and, according to the UK’s Health & Safety Executive, any company that sells them during the COVID-19 crisis must supply documentation to prove that their masks have been tested by an EU notified body.
