Hotel rooms without windows always smell. Is there any way to deodorize for a long time or get immediate results?

Haha, you asked the right person! ! The first method: ozone disinfection and filtration; Ozone machine 120 yuan; Completely kill bacteria, mold and so on! But when it is open, people should not be inside;

The second type: negative ion disinfection method, negative ion generator; Three negative ions can surround an odor ion and fall to the ground, which requires dust collection;
