Face masks are to become mandatory in shops and supermarkets as of July 24 as part of England’s coronavirus measures. Currently it is only compulsory to wear one on public transport, although it has been mandatory in Scotland’s shops since July 10. ITV Good Morning Britain expert, Dr Sarah Jarvis, pleaded with viewers to wear their masks properly and offered advice on the “correct” type to get.
She said: “On the whole we recommend the ones that don’t have a filter.
“There are masks that have filters, the so-called PPE masks, anything with N95 on it or FFB3, but they should absolutely be reserved for healthcare workers because there is a global shortage of them.
“What we do recommend is ideally two layers, preferably three.
“That’s new because we’re now seeing there’s better evidence of you protecting other people if you’re wearing two or three layers.”
Dr Jarvis continued: “In the past, I know Hilary Jones has said anything is okay, and that’s what the evidence was then.
“But now we’ve moved on, and we know it’s better if we’ve got two layers.”
The medical expert specified that she didn’t mean two or three masks at a time, but rather a mask with two or three layers.
She used the example of her homemade version which is made from three layers of material.
Dr Jarvis also dismissed the suggestion that masks could affect oxygen levels.
She explained that they wouldn’t impeded breathing because normal masks come onto faces around the edges.
The expert recommended practising wearing one at home if people were anxious about the experience.
The new face mask rules will be enforced by the police, not shop workers.
Children under 11 years old and those with “certain disabilities” will be exempt.
