The Community is made for enquiries concerning the ownership and use of the products, for all other questions (prices, orders, deadlines, etc.) please contact the customer service.
However, unfortunately, it happens that we sell products with several offers, either in Galaxus offer or in marketplace offer. Sometimes, the supplier chosen at the time of the order may simply not have updated the lead time or stock on our site. In this case, we will cancel the order and refund you. If the same item is available with another offer and a higher product, you can simply contact the service and normally a commercial gesture is possible :)
We apologise if a cancellation has been made without your knowledge. We invite you to contact our customer service (email, chat or phone) to clarify this: https://helpcenter.galaxus.ch/hc...
There should normally be a bracket that fits the filter, which is already supplied with the mask. In addition, the mask description indicates that the mask comes with the necessary bracket to attach the filter: 3M Full Face Mask 6800
So I would say that there is no need to buy anything other than the mask and the filter :)
