Associate Professor Dr. Weeraphon Thongma, President of Maejo University, and Assistant Professor Dr. Nuttawut Dusdi, Acting Vice President gave their honor to donate 15 sets of air purifiers to various organizations within the university on Friday, May 1, 2020, at 10:00 a.m. at the Hall on the First Floor in the University Office Building. Each set was a self-made air purifier (made by Energy and Environment Conservation Work) under the coronavirus disease (Coronavirus Disease 2019) and PM 2.5 prevention project. It was hoped that the organizations would use them to protect their personnel and use them as a model to create ones to use in their organizations, too.
