According to the US Environmental Protection Agency (EPA) indoor air can be five times more polluted than the outdoor air. As indoor air remains enclosed and not circulated as much as outside air, many pollutants tend to thrive inside, which increases the risk of respiratory infections, neurological problems, etc. for the occupants. Pet dander, pollen, dust mites, paint fumes, smoke released from cooking are some of the common types of indoor allergens that can deteriorate the air quality. Besides, lack of ventilation, dirty upholstery, and humid environments contribute to the harmful indoor environment, making children, aged population, and people with chronic conditions more vulnerable to numerous health issues. However, high-efficiency particular air (HEPA) filter can help to clean the bad indoor air by accumulating pollutants. It works to pull air into the machine at the base through a fan, the instilled filters catch the pollutant in the perforations, and the machine then releases the fresh air into the surroundings. A true HEPA filter can remove up to 99.9% of the dust particles, measuring as small as 0.3-micron diameter. Some types of air purifiers have charcoal filters that can absorb odors and harmful chemicals while others have UV filters that kill harmful microbes present in the surrounding air.
