Founded in Hong Kong, PM2.5 Limited were established in 2014 out of necessity to fulfill one family’s promise to provide the best care for their children. In 2010, when our youngest grandchild Ryan was suffering from debilitating asthma symptoms and losing sleep because of irritable skin inflammations, we changed his diet, limited his outdoor exposure, and bought the best leading brand of indoor air purifiers.
While Ryan saw some improvement, the solutions available were not all very effective and his quality of life didn’t meet our standard. We delved deep into our own research of air pollution when the best medical professionals came up short of effective long-lasting solutions and with the help of industry-leading engineers, Team AIRO2 built the first AIRO2 prototype and gave Ryan the only long-lasting solution.
Since then PM 2.5 Limited has been granted six patents in Mainland China and Hong Kong, and we have successfully manufactured eight AIRO2 models. Designed and engineered specifically for Hong Kong and the rest of Asia, our patented fresh air purifiers provide a fresh airflow solution for almost any residential and commercial building, new or old.
