How would this impact the phones water resistance, I wonder? A removable battery would require some sort of user serviceable (breakable) seal on the door.
Maybe they could put the seal at the connection on the battery to the phone instead of around the door where it is likely to get debris lodged in it.
Prob a good reason he didn’t want it in his own office. Maybe mention it to him if you’re comfortable, if not you could email people asking for an air purifier and when asked why explain the printer concern. Health issue, I am not sure but comfort issue absolutely.
