How to remove the odor in the room?

The method of eliminating indoor odor is as follows:

1, the first choice is to open the window for ventilation. Outdoor air comes in to generate convection indoors. At the same time, put a bottle of perfume with the lid opened in the room, and the room will be filled with fresh air in an instant.

2, put a pineapple in the room (need to be whole, don't peel), even if there is no one in the room, you can't open the window for ventilation, it will have a faint fruit fragrance and sweetness, which has a particularly good effect on removing odor.

Put a pot of jasmine in the hall of the room. Jasmine absorbs odor and can adjust the air. At the same time, insist on mopping the floor once a day. The smell in the room will easily disappear, bringing you another fresh and pleasant feeling.
