Further to my post yesterday about the EU recall of Dr Frei reusable face masks I came across this from WHICH testing this morning:
The highest scoring face covering tested was the Airpop Pocket (£24.99for 4), available direct from Airpop or on Amazon. The covering is made from similar materials to disposable masks and does a superb job of filtration - though it is semi reusable so can only be washed a set number of times before it needs to be thrown away.
Other high performers were masks from Superdrug (£4.99 for three), The Big Silk (£16.90 for one) and Marks and Spencer (£9.50 for five) which scored well for filtration, breathability and comfort.
Worst performing were Adidas (£17.00 for a pack of three, sold at retailers including ASOS, Next and Sports Direct and the Vita Shield face covering (£9.99 for three) dropped from 60% filtration to 38% after five washes.
