Air pollution is a major public health issue in India, especially in Delhi which has the dirtiest air of any city worldwide according to WHO. Chronic exposure to air pollution significantly increases health risks and diseases like asthma and COPD. While people spend most of their time indoors, indoor air can be 3-5 times more polluted than outdoor air. New technologies like PHIO+ and CPT can effectively purify indoor air and improve health by generating oxidizing ions and plasma to eliminate pollutants, microbes, and odors while also saving energy. These technologies can help maintain healthy indoor air quality in homes and buildings.
