T42 Economy Mask.Replaceable filter
Price: EUR 140
Why do you need to change the filter in the mask? An old filter will drastically reduce the protection provided by the mask. It doesn't matter if you use the mask a lot or a little, as the filter is activated when it is removed from the packaging and comes into contact with air for the first time.
We recommend storing the mask and filter in a sealed bag or box and insert the mask between uses. This prolongs the life of the filters and avoids getting dust into the mask.
