Unfortunately it is not possible to process the FFP masks from Dräger for reuse.

All FFP masks contain electrostatic filter materials. The charge of these materials is destroyed by heat, radioactive radiation, UV radiation and the like, causing the mask to lose most of its filtration properties. Disinfectants like isopropyl, ethanol and other cleaning agents also destroy the charge of the filter material.

Since all of the aforementioned approaches permanently damage the filter material, Dräger is not working on developing a reprocessing method. In this respect, observe the information provided in the instructions for use for the product in question.

As the manufacturer, Dräger advises against using its FFP masks and respiratory filters if they are expired. It is impossible to make any statements across the board as to how effective they actually still are. For example, an expired FFP3 mask may no longer provide the effective protection required by an FFP3 rating. The reason for this is that electrostatic properties of the filter material degrades as the years progress. Only testing in an approved lab with the appropriate equipment can deliver information based on the EN 149 standard, which can then be checked and measured against the current performance of the mask.

One FFP is good to wear for no more than eight hours, i.e. one shift. If there is an infective agent like a virus in the environment, the FFP must be disposed of as soon as it is taken off. This information is also provided in the instructions for use for the product. One of the reasons for this is the way the mask is put on and removed. When putting it on again, it is impossible to ensure that the potentially contaminated exterior of the mask has not come into contact with the interior of the mask or even directly with the face of the user. Moreover, it is not clear in this process what has happened to the mask in the meantime: after being removed the first time, where and how was it kept? Did any other person potentially come into contact with the mask?

A surgical mask is designed to prevent liquid aerosols from coming into contact with the nose and mouth of the wearer, and to protect others from droplets breathed out by the wearer. A respiratory protection mask (breathing mask) protects the wearer from breathing in fine particles and droplets in the air.

It may be beneficial for a layperson to wear a surgical mask in order to protect others, if the wearer is at risk of spreading infectious agents.

The Robert Koch Institute (RKI) recommends using FFP2 or FFP3 masks as personal protective equipment when treating and caring for patients infected with the coronavirus SARS-CoV-2 (Covid-19).
