DESIGN AND FABRICATION OF INDOOR AIR PURIFIER & HUMIDIFIER IN FOOD INDUSTRY

In 2021, air pollution has gone beyond all limits. According to the WHO, 7 million people die annually as a result of air pollution. A whopping 91 percent of the world's population is now exposed to air pollution due to its wide distribution. This also implies that the air within your home is contaminated. In order to address this problem, we have developed a small air purifier that employs water as an air filter rather than pricey filters. Additionally, it functions as an air humidifier. The design and development of the next-generation indoor air purifier is the subject of this thesis. The project was carried out using a human-cantered design process, and a patient was the end outcome. The system uses two high performance, low noise centrifugal fans to draw air through a safety mesh. At the bottom of the purifier, there is a water tank through which the air is pushed and subsequently passed. Water catches dust, fungi, germs, and other contaminants, which causes the air it passes through to be automatically cleansed. If you suffer from asthma or another breathing difficulty, you may find a HEPA (sometimes defined as "high-efficiency particulate air," sometimes as "high-energy particulate arresting") air purifier (or a vacuum with a HEPA filter) well worth the investment.
