Modified Indoor Air purifier

Abstract: Air purifier filters utilize fine sieves that filter particles out of the circulating air. As air flows into the air purifier, the finer the sieve inside of the air purifier, the smaller the particles it will trap. High Efficiency Particulate Air (HEPA) filters are the benchmark for air purifier filters, which are guaranteed to trap 99.97% of airborne particles larger than 0.3 microns in size. Microns are the standard unit that is used to measure the size of particles in the air. Each micron is equivalent to 1/25,400 of an inch. The naked eye cannot see anything that is smaller than 10 microns in size, so pollutants like bacteria and viruses escape detection. HEPA filters efficiently remove smaller-sized allergens like dust, smoke, chemicals, asbestos, pollen, and pet dander. Room air conditioner filters can only capture particles 10.0 microns or larger, so they are not as efficient as air purifier filters for cleaning the air. HEPA filters are designed to capture particles as small as 0.3 microns, including pollen, dust mites, and pet dander. Activated carbon filters are effective at removing odors and volatile organic compounds (VOCs) from the air. UV-C light is used to kill bacteria and viruses that may be present in the air. Air purifiers come in a variety of sizes and styles, ranging from small portable units to larger models that can purify the air in an entire building. Some air purifiers are designed for specific purposes, such as removing cigarette smoke or pet odours. Air purifiers are essential devices that help improve indoor air quality by removing harmful contaminants. They can be used in a variety of settings to reduce the risk of respiratory problems and improve overall health. With the advancement of technology, air purifiers have become more efficient and effective in removing harmful pollutants from the air we breathe.
