It is said that the key air purifier has adopted NCCO patented technology, and the effect is good. Can I use it in the hotel?

Our hotel is a four-star hotel. The main design problems of hotels in China, such as poor air circulation, mites, bacteria and poor air circulation, are widespread. The air purifier used in our hotel is a fresh key air purifier. Although March and April are the flu season, the cold has said goodbye to us. It's all because of the fresh key air purifier that we have helped so much.
