Solar Outdoor Air Purifier With Air Quality Monitor

The solar-powered air purifier

Pollution has wreaked havoc on the planet, with pollution levels increasing. While the long-term answer to pollution is to identify and minimize pollution sources, we must first bring existing pollution levels under control. The most effective method of pollution management is through the use of air purifiers. However, conventional interior air purifiers are tiny, low-power machines that lack the filtering performance required for outdoor environments. Additionally, there is the issue of power supply for outdoor machinery.

As a result, we created a heavy-duty outdoor air purifier that is designed for outdoor use and is powered by solar panels, making it completely self-sufficient. Our solar air purifier is equipped with a powerful suction fan that draws air from the bottom of the unit through a layer of HEPA and carbon filters, effectively removing PM 10 and PM 2.5 pollutants as well as gases.

The purifier utilizes a two-layer purification system, with the first layer being HEPA and the second being an active carbon filter. The combination of these two filters results in dual filtration, in which a significant volume of air is sucked in and purified of dust particles using centrifugal force.

Now, this suction fan is used to extract air by sucking it out with high-powered centrifugal force and blowing it out from the top. Additionally, the system has an air quality sensor and display that indicates the current air quality. We now power our home with a solar panel. The panel supplies electricity to the battery, which powers the motor that drives the suction fan.

For ease of movement, the machine is equipped with four castor wheels and a handle. This makes the air purifier portable, allowing it to be readily transported to school playgrounds, parks, residential areas, and public locations for effective and immediate pollution control.

Air pollution: a problem that solar-powered air purifiers can help

Air pollution, a dangerous source of contaminated air generated by man-made innovations such as emissions from industries, automobiles, and airplanes, has plagued our age for far too long. This is not just because of the consequences of climate change, but also because of the consequences for individual and public health and welfare as a result of increased mortality and morbidity. Smog is a byproduct of the combustion of fossil fuels and their derivatives that contains a diverse array of particulate matter and greenhouse gases.

The World Health Organization reports that over four million people die prematurely as a result of outdoor air pollution. Karachi, Pakistan; New Delhi, India; Beijing, China; Lima, Peru; and Cairo, Egypt are among the world’s most polluted cities. However, many industrialized countries suffer from air pollution as well. Smog City is a nickname for Los Angeles, California. To reintroduce breathing to the planet, Dutch architect, designer, and inventor Daan Roosegaarde constructed the Smog Free Tower, a twenty-three foot tall (seven meter) air purifier that has grown to be the world’s biggest.

If you spend the most of your time indoors, I recommend looking for the best air purifiers.

How the Smog Free Tower works

The solar-powered Smog Free Tower operates similarly to a vacuum cleaner, vacuuming dust and filth from the polluted environment and releasing clean, purified air for people to breathe toxic-free via the process of air ionization. Air ionization is a well-established technique that has been applied in a variety of applications, including the decrease of static electricity and the separation of particles from the air. « The gadget collects polluted air from the sky and absorbs ultra-fine smog particles with the use of unique ion technology while utilizing the least amount of power feasible. The clean air that is blown out again will create a ‘Smog Free Park,’ a bubble of pure air that we may inhale and enjoy air that is 75% cleaner than the rest of the city. By applying a tiny positive current to the Smog Free Tower, an electrode will release positive ions into the air. These ions will cling to microscopic dust particles. The positive ions, together with the small dust particles, will subsequently be drawn in by a negatively charged surface — the counter electrode. The fine dust that would ordinarily injure humans is collected and kept inside the tower along with the ions. This device is capable of capturing ultra-fine smog particles that are missed by conventional filter systems.

Purifying over 30,000 cubic meters of air every hour

The piece was shown in parks in Beijing, Tianjin, and Dalian, China, as well as in Rotterdam and Kraków. According to Roosegaarde, it operates according to the law of electrostatic energy, which everyone has observed on balloons at some point during their educational careers and as children; friction caused by rubbing a material against an insulator displaces electrons from one side, the positively charged side, to the other negatively charged side. The same is true for the Smog Free Tower: by emitting positive ions into the air, smog microparticles that would normally harm us are attacked and then sucked into the tower’s negative ions, where they are stored – the tower has the capacity to purify over thirty thousand cubic meters of air per hour, equivalent to the size of a soccer stadium in a day and a half when powered by 1,400 watts of green energy. According to Roosegaarde, “what distinguishes our technology from others is its efficiency against all types of fine dust, its low energy consumption, its minimal maintenance requirements, its capacity to clean vast volumes of air simultaneously and at a fast rate of speed”.

There is no waste generated when a smog particle is retrieved from the air

The cleaning radius of the tower is determined by the wind, humidity, and meteorological conditions in the surrounding area. It assures that no waste is generated throughout the air purification process, since the smog particles recovered from the air may be transformed into distinctive pieces of jewelry at the conclusion of the operation. This is accomplished by compressing carbon-containing smog dust into jewelry goods such as rings and cufflinks that include smog dust purified from 1,000 cubic meters of air. Following the tower’s success in China, Poland, and the Netherlands, Roosegaarde and his team at Studio Roosegaarde have attempted to institute and promote a campaign, as well as devote time and effort to arranging workshops with students and teaching them on the value of such undertakings. “New designs must incorporate innovative thinking in order to create practical answers for sustainable living. Occasionally, these initiatives make use of technology that we design from scratch, and occasionally, they make use of concepts inspired by nature”.

The Dutch designer is confident that people are resistant to being convinced just on the basis of facts and figures. His idea for combating air pollution intends to pique people’s imaginations for a new world capable of mobilizing them and enticing them to participate in the solution. “We live in a society where, rather than a scarcity of technology, there is a dearth of creativity. Imagination is how we wish the future to appear, and if we are unable to conceive it, we will also be unable to construct it. That is why we are trapped; we are terrified of the unknown as humans. Prototypes for the city of the future, they are recommendations for how we should begin to view the world; not as a utopia, but as a protopia, to demonstrate, to learn, to fail, and to improve the world around us”.

Prototypes and concepts for the metropolis of the future

With more than half of the human population now residing in metropolitan regions, humankind has extracted resources from all over the earth and concentrated them in cities. While some may claim that these tactics may maintain a contemporary metropolis, others believe that they are a primary cause of the environmental deterioration we are now experiencing as a human species. “There is a Dutch term called ‘Schoonheid,’ which means both beauty and inventiveness, as well as clarity or cleanliness, as in clean air, pure water, and clean energy. These are the future values of our society, and it is only by including them in our new standard that we can begin to progress. These initiatives are blueprints for the city of the future; they are visions of how the world should be, urging everyone to become more sustainable and to contribute to the creation of a more sustainable future”.

Numerous governments have made initiatives to mitigate global warming by reducing or limiting greenhouse gas emissions. Roosegaarde and his team intend to expand the use of smog-free towers to numerous other nations where haze poses a hazard to inhabitants’ health and wellbeing. According to the Dutch designer, “the Smog Free Project is a long-term effort to promote clean air. The seven-meter-tall Smog Free Tower is the world’s tallest air purifier, creating a bubble of pure air that residents may experience for free. We are pioneers in the worldwide arena for the livability of our future terrain. Not just clean air, but also clean water, clean energy, and clean space are our new future ideals, and they should be available to all”.

Daan Roosegaarde is an artist, designer, architect, and inventor who attended the Berlage Institute in Rotterdam to study Fine Arts and subsequently Architecture. In 2007, he established his business, which paved the way for his breakthrough with ideas such as the Smog Free Tower. According to Forbes and Wired, Roosegaarde is one of our generation’s innovators and a NASA Innovation Team member.
