The following personal experience
1. Select glass
Glass is the healthiest and will not produce harmful substances because of high temperature. But glass has a disadvantage that it is hot and easily broken, so you should choose single-layer or double-layer glass as appropriate. Double-layer glass is not hot, and it cools slowly, while single-layer glass is small and cools quickly. For home use, you can choose one without a cup cover. If you need to carry it out, you'd better choose a covered one to avoid dust polluting the water.
Choose plastic cups
Plastic cups are generally cheaper than glasses, but they are made of many kinds of materials. Some plastic cups can hold high-temperature boiling water, but some plastic cups will release toxic substances when exposed to high temperature. Generally, the bottom of the plastic cup will be marked with materials, so I won't give an example here. Just make it yourself.
Be sure to distinguish whether the cup you bought is boiled water or normal temperature water. In order to pay attention to the material when buying, otherwise it is not worthwhile to use unqualified cups to fill hot water, which will damage your health.
3. Insulating water cup
Generally, the price of this kind of cup is higher, and some good ones cost hundreds of dollars. I bought a small thermos cup for my son, more than 200 yuan, which is already cheap, keeping warm and cold. It is a very happy thing to have a thermos cup in winter and drink warm hot water at any time.
Moreover, the shape of the thermos cup should be in various colors, with cartoon characters. You can choose one you like and love drinking hot water.
4. Zisha Cup
You'd better find a professional to accompany you when you buy this kind of water cup. It's easy to buy fake industrial cups without knowing how to do it. It will have a strong industrial smell and do some harm to your health. My husband recently bought a small cup from 20 yuan on the Internet, which is very small and funny. When he bought it home, he found the cup stinky, and then hung it on the balcony. It didn't dry, so I advised him not to use it, so as not to drink it badly.
A good purple sand cup is good for your health. You can find information online to avoid buying fake ones.
5. Ceramic cups
Ceramic cups we also become mugs. White-collar workers usually put a mug on their desks. Girls will choose cute ones, and boys will choose big ones. Anyway, ceramic cups are clean, hygienic and easy to take care of, which is suitable for drinking scenes frequently. However, it is recommended to buy a mug with a lid to avoid forgetting to drink water when you are busy with work. There is little dust in the water.
