The repeated circulation of the same air throughout the space is the first issue with air conditioning. This implies that if someone sneezes or coughs, the germ will stay in the air and spread throughout the office for the remainder of the day. As more and more people sneeze over time, bacteria begin to accumulate, increasing the likelihood that you’ll breathe something unfavourable. Because of this, the room’s overall bacteria content will increase significantly as a result of your confinement. The same is true of dust, the majority of which is composed of dead skin, and allergens.
