According to the United States Environmental Protection Agency (EPA) indoor air can be five times more polluted than outdoor air. Since indoor air remains enclosed and does not circulate as much as outdoor air, many pollutants tend to thrive indoors, increasing 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 air quality. In addition, lack of ventilation, dirty upholstery, and humid environments contribute to the harmful indoor environment, making children, the elderly population, and people with chronic illnesses more vulnerable to numerous health problems. However, the special high-efficiency air (HEPA) filter can help clean polluted indoor air from contaminant buildup. It works to draw air into the machine at the base via a fan, the installed filters trap contaminant in the perforations, and the machine then releases fresh air to the surroundings. A true HEPA filter can remove up to 99.9% of dust particles, as small as 0.3 microns in diameter. Some types of air purifiers have carbon filters that can absorb harmful odors and chemicals, while others have UV filters that kill harmful microbes in the surrounding air.
Here is a list of the top ten air purifiers that provide effective protection against indoor pollutants.
