Plastic cups are cheap and not afraid of falling, so they are very popular with office workers. It is best not to use plastic cups in the office. The first choice for drinking water should be a glass. Don't think that glass is just transparent and beautiful. Among all the cups made of materials, the glass is the healthiest. Heating plastic cups will precipitate some chemicals and easily breed bacteria. Although the plastic surface looks smooth, in fact, there are many cracks, which are easy to hide evil and shelter evil. In the office, people only use clean water to wash cups, and cups cannot be thoroughly cleaned and disinfected. Experts suggest that it is best to use stainless steel cups or glasses in the office and clean them every day. It is best to use detergent and wash with hot water. In addition, the cup is affected by static electricity such as computers and cabinets, which will absorb more dust, bacteria and germs and affect health for a long time. To this end, experts suggest that it is best to provide a lid for the cup and keep it away from computers and other electrical appliances. Usually, we should keep the indoor air circulating, open the window for ventilation, and let the dust go with the wind.

Hope to adopt, thank you.
