What measures should be taken at home to effectively prevent aerosol transmission?

At home, the following measures should be taken to prevent formaldehyde from spreading aerosols and droplets and indoor pollutants: 1. Open the window often and get plenty of ventilation. Window ventilation can effectively replace indoor and outdoor air, dilute indoor air pollutants such as CO2, formaldehyde and TVOC, and dilute indoor aerosol virus concentration. 2. Do a good job of indoor sanitation and disinfection regularly, especially household appliances such as air conditioners and computers that are easy to accumulate dust and bacteria, as well as places such as bathrooms and kitchens that are easy to breed germs; 3. When the outdoor air is bad, close the doors and windows in time to avoid being infringed by outdoor pollutants. At the same time, it is recommended to buy fresh air air conditioners, air environment machines and other products with fresh air disinfection function, and families with conditions can choose to install fresh air systems. At present, I use EBC fresh air sterilizer in my own home. In foggy days or back to the south, indoor and outdoor ventilation can be realized without opening the window.
