Structure of the masks

The inner fabric is antiviral and antibacterial. It destroys viruses as well as its own and foreign bacteria.


A high-performance filter holds back viruses and dust. Due to its special nature, it does not offer viruses and bacteria any survival space.

Splash guard

The outer fabric has a special liquid-repellent coating and protects against infections caused by coughing and sneezing.



Avidef Model D (2021)

Mask with front seam and therefore optimal dimensional stability. High protection factor through special seam. Large air reservoir.


Avidef Model E (2021)

Mask without seam inside the mask. Maximum protection factor. Due to the special processing of the inner fabric, an enormous amount of space was gained for an even larger air reservoir.

Avidef Model E + (2021)

Like model E but with 30% more breathing space and a special construction on the inside of the mask, which prevents the mask from being pressed to the mouth even with air pressure from outside and air suction from inside. Ideal for athletes with high air requirements and / or airflow. Also perfect for choirs. Model E + can be produced with even more breathing space on request.


Avidef model E2

Like model E, but with an extremely powerful filter. Ideal in environments with Covid-19 infected people and high protection requirements. The breathing resistance is slightly higher than that of model E.


Avidef Model F (2021)

Top security as with model E. Perfect fit of the mask. No mouth contact, the inside does not get wet. Optimal breathability as there is no tubular material covering the mask. Supple and stretchable hose material. Adjustment of the size of the hose diameter is easily guaranteed.

Binding systems


Ear loop

The ear loop is suitable for frequently putting on and taking off the mask. This when shopping and when visiting public institutions, restaurants etc. The locking devices are made of soft material and cannot be felt. They can be used to increase or decrease the pressure of the mask on the face as desired.


Head loop

The head loops are beneficial if the mask is to be worn for a long period of time. It relieves the ears. Since there are two loops, there is no complicated knotting at the back of the head. The elastic band can be adjusted quickly and easily with locks.
