Take off the mask in English

The English translation of "Take off your mask" is "Take off your mask"

"Take off your mask" means asking the other person to take off their mask. Masks are generally used to protect the respiratory system and prevent the transmission of viruses and other pathogens, so they need to be worn in certain situations, such as in hospitals, public transportation, crowded places, etc. But in some situations, such as at home, in a personal space or when it is necessary to show facial expressions, it may be appropriate to remove the mask.

"I can't understand you with your mask on. Could you please take it off?" (I can't hear you clearly with your mask on, can you take it off?)

So you can use this expression when you want to ask someone to take off their mask.
