What should I do if the residential area kills the first floor?

Solutions such as closing doors and windows, using air purifiers, and contacting property or management.

1. Close doors and windows: When smoke sterilization, closing doors and windows can prevent sterilization gas from entering the room.

2. Use air purifier: Indoor air is still affected, so you can turn on the air purifier.

3. Contact with the property or management: contact with the residential property or management in time. It can help to better understand the disinfection scheme and measures, put forward their own needs and opinions, and better protect the health of themselves and their families.
