Dust particles affect the respiratory system and also generate dust and dirt. The presence of chemicals (TVOC, total volatile organic compounds, OR HCHO, Formaldehído) also affects the respiratory system and cause eye discomfort. When sweeping, you are moving particles instead of removing them. If you are trying to reduce dust and chemicals at home, use a vacuum cleaner. If you have air-power heating/cooling systems, keep in mind that dirt and dust filters that are not changed regularly can lead to dusty surfaces and particles in the environment.
