Which company is better in Huai 'an and in addition to formaldehyde?

Jiangsu Yanjing Environmental Protection Engineering Co., Ltd. has done a good job in Huai 'an and has a good reputation. My home is in Yili Future City, and I asked them to do it. I found them in June 5438+last February in in addition to formaldehyde. After five days of formaldehyde removal and ventilation, there is basically no odor in the room. The smell was pungent when I opened the door before, and I felt dizzy after staying in it for a while. The formaldehyde content was 0.36 at that time. Highly recommended
