Retention capacity of The Proper Mask vs. FFP2 masks: Mas-Q-Check by palas

The Proper Masks retention performance is significantly better compared to a normaly worn FFP2 mask due to its perfect fit and gapless sealing.

  • FFP 2, normal fit 30% 30%
  • The Proper Mask 80% 80%
  • FFP2, pressed down on face 80% 80%

Several studies were conducted at the TUM, including a high performance physical exercise test at the exercise biology lab, confirming the mask’s breathability.

In another scientific study conducted at the Chair of Analytical Chemistry and Water Chemistry at the Technical University of Munich, the filter of The Proper Mask achieved a retention capacity of well over 99% - in other words, the number of aerosol particles over the Covid relevant size range was reduced by more than two orders of magnitude.

The filter efficiency remains high even when wet.

According to the expert commission’s report, masks play a vital role in preventing the spread of airborne and aerosol transmitted diseases. The Commission also stated that this holds particularly true indoors and whenever safe distances cannot be maintained.

Furthermore, it is critical that the mask covers the mouth and nose permanently and that the mask allows no leakage, making The Proper Mask the ideal protection whenever it matters.

What our customers say about our masks

This is a revolution! I had to go 4h by train to attend a business meeting and this mask changed my world – breathing is way easier, it fits perfectly and I felt save during the whole trainride.

As a doctor, I need to make sure to be safe for myself and my patients. Wearing The Proper Mask essentially throughout the day, I really appreciate its comfort and easy breathability. But what convinced me the most was that my patients could understand me well again.

I'm a waiter and have to wear a mask all the time during work. All the masks I've tried didn't fit well and became itchy and warm over time. Now I sometimes even forget that I'm wearing a mask at all!
