Kassensturz test results

Filter performance of the filter

In Kassensturz, the filter performance of goSnow was rated at 99%, as good as that of the test winner. In contrast to the test winner, petertools also had the goSnow tested for aerosols of 300nm size by Testex AG in Zurich/Vienna. With these, goSnow achieves a filter performance of 97%.

(Air) resistance of the filter

A good filter performance is always in conflict with the air resistance, especially if the filter almost completely retains aerosols of 300nm size.
The tested effect of air resistance can be simulated as follows: 1. Press the goSnow with the filter surface in front of the mouth and breathe through the fabric. 2. 2. then put the goSnow on correctly (as in the picture below) and observe the breathing. You will notice that the air resistance is much greater with 1. than with 2.

In the Kassensturz test, the filter performance of the petertools goSnow was determined to be 99%!

Made in Switzerland

goSnow was developed in cooperation with the sewing factory IDM in Thun. To ensure a sufficiently efficient production, petertools cooperates with various small sewing workshops and training centres in Switzerland and, of course, all raw materials are also purchased in Switzerland. Production outside of Switzerland was out of the question for us, as we consider it a challenge to create opportunities for others to earn money in these difficult times.


We are very pleased about the order at petertools. As soon as the sale is completed, the women will start packing and shipping at the Hindelbank prison. So that our customers will soon benefit from the protection of goSnow.

How to wear goSnow

The goSnow tube scarf was developed for use while skiing. During a day on the slopes, two main situations alternate. On the one hand, the movement phase outdoors, on the other hand, the queuing before boarding the gondola or ski lift as well as the ride in the cable car. While skiing, the risk of infection is practically zero, even without wearing a ski scarf. The dangerous situations occur when queuing in front of the lift and much more extremely in the gondola.

goSnow is worn relatively snugly around the head and securely closed at the nape of the neck with the Velcro fastener. The triangular shape makes it possible to wear goSnow in the front part under the ski jacket. The ski scarf is made of a soft and elastic organic cotton sweat, which can be stretched well and thus sits very non-slip over the mouth and nose.

It is important that the ski scarf is pulled over the mouth and nose as soon as a woman gets into a crowd, disappears under the ski jacket as shown in the photo on the left and the jacket is zipped up to the top. This ensures that you only breathe through the membrane filter and that you are optimally protected in dangerous situations.

The Bionicman uses the One-Hand Community Mask

Michel Fornasier was born with only one hand and now, as the superhero Bionicman with his prosthesis, he is setting out to “unravel” the world, as he says, together with other affected people. The One-Hand Community Mask convinced him from the very first time he wore it. “Daniel Peter has succeeded here in creating a great innovation that fits my concept perfectly: It is a tool that will help many people to relieve themselves! The One-Hand Community Mask means a piece of independence for me”. From the sale of the petertools Community Mask, a contribution will flow into Michel Fornasier’s foundation Give Children a hand. “We want to help children with a handicap to move better in life. With our “Prosthetic Hand” project we help young people to lead a better life. The prostheses are produced on ultra-modern 3D printers and enable the young wearers:inside undreamt-of new possibilities.”
