It’s not very scientifically grounded, this ‘journalism’. Note how Adam Speight relies upon implication and fails to mention the particulate size of coronaviruses (80 to 120 nanometres). In passing, he states vaguely that N95 and FFP2 masks are ‘more effective’ than cloth masks.

So there are more questions than answers and we the public are left floundering.

In chasing his payday, the question Adam Speight is deliberately skirting around is this…

How effective are cloth masks against viruses?

If we know this then we get some measure of how effective N95 and FFP2 masks are.

Answers can be found here inside 42 historical, peer-reviewed scientific studies, all undertaken before the government and media endorsed hysteria descended, and all confirming to varying degrees that cloth masks are ineffective against viruses:
