As we all know, we need fresh air in our life. Fresh air is vital to our health. Without air, humans and animals can't live. We should protect the air from pollution and protect our common home.

Usually, we can plant more trees, because plants can absorb carbon dioxide in the air, release fresh air and provide oxygen for our daily life. When we go out, we should drive as few private cars as possible and take more buses to reduce the air pollution caused by automobile exhaust gas, thus minimizing the pollution to our living environment.

If it is indoors, we also have good ways to keep the air fresh. For example, classrooms, dormitories, and homes should always open windows for ventilation, so that air can circulate, turbid air can be discharged, and fresh air can enter the room.

Windows are often opened in the room, which can purify the air, and can also be disinfected by sunlight. In addition, through active cleaning, our indoor environment is clean and healthy, which is beneficial to our health.

If you want to breathe fresh air every day, you must start from me now and work together to protect the environment.

In the morning, when we open our eyes, there are layers of fog outside the window, trapping the whole world in ashes. In the evening, but when we got off work, the fog didn't decrease much. I decided to make an air freshener.

Air freshener is an automatic man-controlled all-around machine flying in the air. It has many functions. Let me tell you first! Function 1: There is a device for measuring pm2.5 and three outlets for fresheners. If the measured pm2.5 is slightly polluted or above, it will automatically fly into the sky, open the first air outlet, and let the small and medium-sized fresh people each send one.

If after a while, the air becomes fresh and the value of pm2.5 drops, it means that the hair has been done successfully. If you don't drop it, send another big one. Function 2: Refreshing agent is a unique sun-exposed pm2.5 removal powder, but it takes a long time to prepare. The freshener can be placed directly on the ground, which is more convenient to wrap up and use. It evaporates in 2-3 hours.

It's not enough to let air fresheners reduce smog, it needs everyone's efforts! We want to reduce fireworks, so we can put less, so we don't put more!

Everyone must pay attention to it, pollute the environment less and be a green messenger!
