Information on quality assurance in the manufacturing process of Atemious pro respirators

As a manufacturer of personal protective equipment for people, especially in the care and medical professions, it is a matter of course for us to ensure the best quality. The manufacturing process of the Atemious pro respirators is therefore continuously monitored so that each individual mask can be traced.

Quality assurance includes testing the filter material, the so-called meltblown. (Information about the meltblown here in the knowledge blog). The requirements for particle filtering respiratory protection are 94%. Each roll of meltblown is tested at several points on the winding in our own test laboratory. Only materials that separate at least 98% of aerosols are used. This is done as in the certification tests with sodium chloride solution.

The filtering effect of the meltblown can vary by up to 2% per roll, although our measurements of the roll run show that on average there is more of an upward deviation. Random samples that are regularly tested in our own UniLab test laboratory confirm this; the vast majority of respirators have a filter performance of more than 99%. In any case, each mask is always well above the 94% filter performance required for FFP 2 masks.

Traceability is ensured by the time stamp on each individual mask, which you will find on the outer left side. The date indicates the shelf life, which is legally limited to three years. For example, if it says 12/08/2023, the mask was produced on 12 August 2020. The three letters in the middle indicate the production line. Our eight lines are marked from UMA to UMH. UMC means for example the 3rd line etc. The sequence of digits after the line ID indicates the exact production time in the familiar hour/minute/second format. The stamping of each individual mask makes it possible to trace back exactly which meltblown, fleece, nosebands etc. have been used. For each line a digital diary of the production equipment used is kept without interruption.
