But speaking loudly and singing can spread even more droplets, which then have the capacity to linger in the air, particularly in indoor spaces with inadequate ventilation . Air cleaning devices that have a HEPA filter will reduce particles in the air and can be used in rooms with poor air circulation. If portable fans or air conditioning units are used, they should be set up to avoid blowing air directly from one person's breathing zone to other occupants of a room. Horizontal cross breezes should be avoided
