Our Premium cotton-spandex blend has a filtration efficiency of 97% for droplets under 300nm in size and a 99.2% filtration efficiency for droplets over 300nm.
This is why we can confidently say there is categorically no way you will be able to blow out a candle from 1m away while wearing our face coverings, proving our effectiveness at blocking air transfer.
If you can blow out a candle from 1m away wearing our mask, then we will refund your purchase and send you a packet of Percy Pigs.
Disclaimer - Our face covers are NOT medical grade or PPE. If I were you I wouldn't wear it on the operating table.
