I'm curious, what's the new vacant room like?

The new vacant room is the abbreviation of fresh air room, and the facilities are actually the same as those of ordinary rooms, except for a set of equipment for purifying the air with algae calcium. The equipment seems to be called Gleason algae calcium air purifier, and there is also a algae calcium air purifier. If you are curious, you can go to a hotel with a smog room to experience it.
