Ruumiõhku

Ruumiõhku, often translated as "room air" or "indoor air," refers to the atmosphere within enclosed spaces such as homes, offices, schools, and other buildings. It is distinct from outdoor air due to differences in composition, temperature, and humidity, which are influenced by both external conditions and internal activities. The quality of ruumiõhku is a significant factor in human health, comfort, and productivity.

The composition of ruumiõhku is a dynamic mixture. Primarily, it consists of nitrogen (approximately 78%) and oxygen (approximately 21%), with smaller amounts of argon, carbon dioxide, and trace gases. However, numerous pollutants can be introduced from both indoor and outdoor sources. Indoor sources include building materials, furnishings, cleaning products, personal care products, cooking, and human respiration. Outdoor sources are drawn in through ventilation systems or infiltration and can include particulate matter, pollen, and industrial emissions.

Maintaining good ruumiõhku quality involves controlling the concentration of these pollutants. Ventilation, whether natural (opening windows) or mechanical (using fans and air handling systems), plays a crucial role in diluting and removing indoor contaminants and supplying fresh outdoor air. Air purification systems, such as filters and purifiers, can also help reduce the levels of airborne particles and gases. Factors like temperature and humidity also affect perceived air quality and can influence the growth of mold and dust mites. Poor ruumiõhku quality has been linked to various health issues, collectively known as Sick Building Syndrome, which can include headaches, fatigue, and respiratory problems.
