What are the misunderstandings of the elderly buying water cups?

1. Cheap is good

Many elderly people think that the same daily necessities, the cheapest is the best value for money. The editor is not very familiar with other categories of daily necessities, but the editor is professional in the water cup. The editor said responsibly that more than 90% of the "cheap" water cups understood by the elderly are substandard products.

2. Plastic water cups are healthy

Not all plastic water bottles are healthy. In order to attract the elderly to buy, some unscrupulous merchants will use recycled materials for production at a very low price, and then attract the elderly to buy at a low price.

3. Stainless steel water cups are safe

Similarly, not all stainless steel water cups are food-grade safe, especially some bad e-commerce platforms attract the elderly to buy a stainless steel thermos cup for a few yuan. Most of the materials used in such water cups are not 304 stainless steel. Although the water glass is stamped with 304 stainless steel, this cannot be believed, because there is no legal and institutional requirement that the material name must be marked. These are the actions of the water bottle factory itself, so there are many versions in the water bottle market that show the wrong version of the actual material.

4. Aluminum cups are harmful to health

Many elderly people think that aluminum has heavy metals, so aluminum water cups will not be used and will not be purchased. This idea is wrong. The safety of food-grade aluminum is not lower than that of 304 stainless steel, and even exceeds 304 stainless steel in some attribute indicators, so the water cup made of food-grade aluminum can be used with confidence.

5. The insulation cup only uses the insulation time as the identification of the quality of a water cup

The shape of the water cup is different, and the production process is different. Although the heat preservation time of all stainless steel thermos cups must be different. There are international and domestic industry standards for the duration of heat preservation. It does not mean that the longer the heat preservation time, the better the water cup is. Usually, a thermos cup is a qualified thermos cup with a heat preservation time of 6-8 hours. If it is too hot, it will affect the need of the elderly to replenish water in time.
