It is unfortunately not as simple as open your window and let in some "fresh" air, especially not if you live in a big city. The outdoor air in cities is dangerous and should pass through the ventilation system before entering. A good advice to solve air quality problems in apartments, homes and offices, involve actions like eliminating or controlling the sources of pollution, increasing and maintain ventilation systems, and installing air purification devices.
