How it works

Made with 5 layers and with a patented nano filter technology, the Kosette washable mask filters our particles such as bacteria and dust, helping to prevent infection and pollen/dust allergies. while increasing your airflow by 95%. Completely reusable. Conforms to KF80/KF95. PM2.5.Nanofibre is certainly an excellent form of filtration for viruses and bacteria, helping filter out even the smallest particles, being lightweight whilst adapting and moulding to the skin.

Unlike disposable masks this Kosette mask can be washed about 40 times, giving up to 3 months protection.



Measure the face, from the bridge of the nose to chin and then across the nose to the ears (bear in mind the straps will form part of the fit also, the mask will not go all the way to the ears).  Please note these are non-returnable products due to hygiene reasons.

As a note, most European faces require the large mask. It is better to be large and adjust to make smaller than to be too small.

The medium is perfect for teens, and smaller adults.
