Composition of air purifier

In normal study, work or life, we often see the figure of composition. According to different genres, composition can be divided into narrative, expository, practical and argumentative. So, how to write a composition? The following is a sample essay (7 articles in general) of air purifier I collected for you, for reference only. Welcome to read it.

Air purifier composition 1 Whenever autumn approaches, the air quality in Ningbo will decline. So my family bought an air purifier, which can make the indoor air extremely fresh. It's Blueair270Eslim.

The air purifier is a cuboid with a length of about 43 cm, a width of about 24 cm and a height of about 5 1cm. The whole fuselage is as big as a suitcase. It has an all-metal body and the whole body is white. It is simple, generous and beautiful, and it is like a work of art full of modernity in the room. It is mainly divided into three parts: shell, filter screen and turbine. There is an air inlet behind the air purifier, and the air inlet has a filter screen containing activated carbon. The filter is like a soldier, closely guarded to catch "bad elements" in the polluted air and prevent fish from escaping through the net. Above the air purifier is an air outlet from which filtered fresh clean air is slowly blown out. Next to the air outlet, there is a blue LED screen, which can show the indoor air cleanliness.

If you think this air purifier is just good-looking, it is all wet. Its function is also very powerful. Its cleaning efficiency is very high. Put it in a room of 20 square meters, and the air in the room will be clean in about 10 minutes. Although it has high efficiency, its noise is very low, and even in the silent night, its running sound can hardly be heard. Its energy consumption is also very low, and it is almost negligible after a day's work. It is also an intelligent air purifier, and the machine can adjust the air volume of the outlet air in real time according to the data on the LED screen. The judgment of the whole intelligent system can be compared with manual adjustment.

I remember that one winter, the air quality in Ningbo was very poor, so I opened an air purifier at home. When I go to school in the morning and walk out of the house, I obviously feel the difference between indoor and outdoor air: the air at home is fresh, the air outside is turbid, everything looks covered with a layer of gray fog, and it tickles after inhaling the turbid air into my nose. This shows that the purification effect of this air purifier is very good. Indeed, it can filter out several indoor particles harmful to human body, such as bacteria, dust mites, pollen, PM2.5 and so on. It can also filter out about 96% formaldehyde in the air-a gas harmful to human body.

I like this air purifier very much. Beautiful appearance, low energy consumption and high cleaning efficiency. Is a right-hand man to purify the air in our house.

I am a happy air purifier, and I keep blowing in spring, summer, autumn and winter!

I wear a golden coat, have a beautiful cuboid figure, and my beautiful big eyes on my face are particularly charming. According to the indoor air quality, I can change the flashing color. Red represents the worst air, pink represents the average air, and blue represents the best air, which is also my favorite color. There are a lot of blue buttons on my head, through which the young master commands and controls my various behaviors.

Every time the young master comes home, he will hug me warmly, as if to say, thank you, thank you for your hard work! Then press the switch, the clean wind blows, and I work happily. Sometimes, I will play naughty louder and louder, making the young master a little angry, and then I will shut up quietly at once.

Every night, my little master needs fresh air when he sleeps. I will continue to work hard. In order not to disturb his sleep, I will switch to the "silent" mode, quietly purify the air in the bedroom and wait for her, waiting for the moment when the young master wakes up and calls me to start full steam again!

Although I have a strong ability to purify the air, there are times when I can't do anything. Let's say winter in Chongqing, the weather is always foggy. In the morning, the original clear objects around become very blurred, as if immersed in milk. The little master's father said that this is the haze weather. Haze is a tiny dust particle floating in the air that we can't see with the naked eye, which not only affects our sight and air quality, but also easily causes respiratory diseases such as sore throat and asthma. Whenever this time, I feel ashamed, because I can only protect my young master from the smog at home, and there is nothing I can do on the road or at school! I really want to be a schoolbag or a red scarf, so that I can protect my little master anytime and anywhere every day!

Yesterday, I watched my young master sleep and had a beautiful dream that I became a "super air purifier", flying in the sky like an airplane, purifying and protecting the air of the whole city from smog, and giving everyone a clean and fresh air environment. Everyone is very happy at work, study and life!

This is me, a happy and dreamy air purifier!

Recently, the air pollution is very serious, which makes many people suffer from diseases. In order to purify the air pollution, my father bought two pots of chlorophytum. Put it at home to purify our air.

Its leaves are long and thin and soft, but the color is a bit special. The middle of each leaf is green, but the edge is pale yellow, like lace. My mother told me: this is Chlorophytum in Phnom Penh, as well as Chlorophytum in Golden Heart, Chlorophytum in Lipstick, Chlorophytum in Goldfish and so on. These strange names aroused my interest, so I looked up the varieties and pictures of chlorophytum on the Internet, which was really dazzling. Some chlorophytum has beautiful flowers, and the stems of some chlorophytum have fallen off a lot. Chlorophytum can not only decorate the room, but also purify the air and absorb toxic gases. The new furniture will smell strange. With chlorophytum, you can sit back and relax.

When my father left, he specifically told me: Chlorophytum should be watered frequently, and this task is left to you. I was very happy, but I always forgot the other day. Fortunately, my mother reminded me that under the careful care of our family of three, Chlorophytum is growing happily. Two new leaves have grown! I look forward to the day when my chlorophytum blooms. What kind of flowers will it bloom? Yellow? Red? Alas! Wait patiently!

The air in our house will be left to you in the future! Lovely chlorophytum, I will take good care of you!

Although the technology is developed now, the air pollution is serious. Now it is often said in the news that air pollution has seriously polluted the ozone layer, leading to the phenomenon that the temperature is hot and cold and the temperature is unstable. So I want to invent a temperature converter.

My air converter makes up for the bad air. Putting it in the room is not only beautiful, but also makes users feel relaxed and happy.

My invention is improved from several characteristics of trees-trees can absorb carbon dioxide and use sunlight to produce photosynthesis, thus releasing oxygen.

My air purifier is made of the characteristics of bionic trees. My air purifier can not only absorb odor and convert it into oxygen, but also absorb some tiny bacteria invisible to the naked eye, and then convert it into sugar through the small holes inside and then into electric energy to continue working. Now it is really a low-carbon energy-saving product!

This air converter can also treat some diseases caused by pollution.

One day, an old man in the hospital fainted because of the virus. Just when everyone was at a loss, a young man stood up and cured the old man with an air purifier.

You said my air purifier was amazing!

I have an air purifier at home. Although it is less than half my height, it can play a great role.

Its structure is divided into four parts, the bottom is the base, the middle is the fuselage (the main body of the machine), the top of the fuselage is the outlet for breathing fresh air, and the top is the button. The base is used to support the upper part of the body, and the fuselage is also used to suck the air. There are five buttons, the first is the master switch; The second is the child lock to avoid children's misoperation; The third is the light switch, which switches the light according to your preference; Fourth, wind speed adjustment, automatic mode, 1-5 wind speed; The fifth is the timing mode.

The brand of this air purifier is Philips. It is 69.8 cm high, 36.6 cm long and 25. 1 cm wide. It can purify particles of 0.02 micron, which is about the size of a microorganism. There are lights on its air outlet, and each light has a different meaning. Blue: the air is good; Dark blue: harmful to people with low resistance; Purple: the air is unhealthy; Red: Very unhealthy. PM2.5 is inhaled from the base and fuselage of air purification, and comes out from the air outlet after purification, becoming fresh air.

This air purifier is very easy to use. I remember once, the air pollution outside was very bad, and the PM2.5 was about 300. My mother coughed desperately. My father took out the purifier. When it is turned on, the indicator light turns red. After a while, the indicator light turned purple. I feel the air is much fresher, and the indicator light slowly turns into deep purple and blue. When it turns blue, my mother doesn't cough, and I feel comfortable all over. Father said: "With this magic weapon, we are not afraid of this smog."

I said, "This is called' the air purifier is in hand, and the smog is all scared away'". After that, we all laughed.

Since the smog began to affect our study and life, my classmates and I have complained. So, I want to invent a miniature air purifier.

This air purifier is colorless and transparent. Although it is only as small as a nano-robot, it is full of power! Numerous miniature air purifiers were thrown into the sky by helicopters. They were made of a new material "plastic cotton". Not only is it light, but it will never fall. Just throw it into the sky and it will start the internal chip. Although this chip is insignificant, it is one million times as large as the current domestic air purifier chip. When working, it will automatically filter the particles in the air.

You may ask, what if the micro air purifier is crowded with the sky? Hey hey, this question is too simple. You can take them back by helicopter, and when the smog strikes again, you can continue to throw them into the sky by helicopter. You may have to ask again, what if these air purifiers are all particulate matter? Oh, don't worry, they have automatic cleaning function inside their bodies, which can filter the dirty things in their bodies into fresh air and double them into the air.

With this miniature air purifier, we will no longer be disturbed by smog, and the sky will turn blue every day!

Air purifier component 7 air purifier, maybe everyone knows what it is. Some people also have air purifiers at home, but the air purifiers I want to talk about are not the kind at home. The air purifier I want to talk about has a great function.

Nowadays, people are suffering from air pollution. Exhaust gas from automobiles and smoke from forest fires will pollute the air and endanger human health. At this time, my air purifier can play a great role. Unlike the air purifier at home, it can only absorb indoor carbon dioxide. Just install air purifiers in roads, factories and other places with serious air pollution, and then install a mini carbon dioxide emitter on everyone's clothes, hair salons and even shoes. When people reach the place where the air pollution index exceeds the standard, the mini carbon dioxide emitter will transmit the surrounding carbon dioxide to the air purifier. At this time, let people enjoy the forest bath like bathing in the forest.

Speaking of which, people who love beauty are afraid that mini carbon dioxide emitters will affect your clothes, right? Don't worry about this, because my carbon dioxide emitter is 1000 times and 10000 times smaller than ants, and it is invisible to the naked eye. The air purifier is only as big as a box, so it won't get in the way.

If one day in the future, my air purifier is really invented. Then, there may never be smog in Beijing again, and people will not feel distressed by air pollution, and they can breathe healthy air every day. Ah! How wonderful all this will be!
