Are you still using bottled water?
Bottled water needs to be delivered to the door manually. It is troublesome to wait about time. Moreover, the product is bulky and difficult to replace. The water in the bucket has a drinking time limit of 7-15 days, beyond which the bacteria may exceed the standard and cause human illness. In addition, the water dispenser must be disinfected regularly. It should be cleaned and disinfected once every three to four months in summer and six months in winter. If it is not cleaned, a large number of bacteria, residues and even red insects will breed and adhere to the inner wall of the hot bladder. When these substances enter the human body, they will cause diseases in the digestive, nervous, urinary and hematopoietic systems.
The secondary pollution of drinking fountains is mainly caused by the fact that the dust in the air carries a large number of microorganisms. Algae, etc. enter the drinking fountains along with the air, especially the air outlets. The sewage outlets are easy to form dead corners, and the microorganisms multiply in large numbers. Over time, they can reach the level of endangering human health.
