1, choose energy-saving and environmental protection. Because the microwave field interacts directly with the heated food without any medium, there is no extra heat consumption, which can save electricity by 30% compared with electric furnace heating. When purchasing, you should check whether there is an energy-saving sign on the product.

2. Choose one that is evenly heated. Microwave ovens are mainly used to heat food. If the heating is uneven, it will affect the eating of food. When choosing, we must pay attention to microwave heating. Microwave heating is the simultaneous heating of the whole heated food inside and outside.

3. Choose a fast heating speed. Most food is a poor conductor of heat. If conventional heating is used, it will take a long time, while microwave heating can cook food in a short time. Therefore, the microwave oven with fast heating speed is more worth buying.

4, choose easy to clean. Microwave oven is also a common electrical appliance. If it is used frequently, dirt will adhere to the inside and outside, which may cause failure. But cleaning is a troublesome thing, so it is best to choose a microwave oven that is easy to clean and convenient to maintain.

5. The power consumption is more affordable. When buying a microwave oven, we should consider its power and power consumption, because microwave ovens are high-power appliances and have high frequency of use. If the power is too large and the power consumption is high, it will be impossible to save energy and electricity.
