2- HEPA Filter Upgrade in Air Handling Units, Things to Pay Attention
IAQ
Indoor Air Quality (IAQ) refers to the quality of the air inside buildings and structures, as it relates to the health and comfort of the occupants. It encompasses various factors, including the presence of pollutants, temperature, humidity, ventilation, and odors.
Poor indoor air quality can result from a variety of sources, both external and internal. External sources include outdoor air pollution, allergens, and contaminants that enter the building from the surrounding environment. Internal sources can include building materials, furniture, cleaning products, volatile organic compounds (VOCs) from paints and adhesives, tobacco smoke, cooking emissions, and biological contaminants like mold and bacteria.
Exposure to poor indoor air quality can have negative effects on human health, leading to symptoms such as respiratory problems, allergies, headaches, fatigue, eye and throat irritation, and exacerbation of existing conditions like asthma. Long-term exposure to certain indoor air pollutants may even increase the risk of developing respiratory and cardiovascular diseases, as well as certain cancers.
Improving indoor air quality involves various strategies, such as proper ventilation, filtration, source control, and maintenance practices. Adequate ventilation helps to dilute and remove indoor pollutants by bringing in fresh outdoor air. Filtration systems, such as HVAC filters and air purifiers, can capture and remove particles and contaminants from the air. Source control involves minimizing or eliminating the use of products and materials that release pollutants. Regular cleaning, maintenance, and addressing any moisture issues can help prevent the growth of mold and reduce the presence of other biological contaminants.
Monitoring and testing indoor air quality can be done through professional assessments or by using portable air quality monitors. It is important to maintain good indoor air quality to provide a healthy and comfortable environment for building occupants.
