Toilet Ventilation System

How many times did it happened to you in any hotel, even with many stars, after using the toilet, to have to wait a long time for the complete ventilation of the bathroom? The current systems make ventilation of the toilets with the fans mounted in the ceiling of the room, having the disadvantage that the smells in the first phase are scattered into the room and then being evacuated outside. The TVS aspire odors directly from the toilet bowl, preventing their spread into the room and evacuating them to the sewerage network.
