Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns.
AQI value of 100 generally corresponds to an ambient air concentration that equals the level of the short-term national ambient air quality standard for protection of public health. AQI values at or below 100 are generally thought of as satisfactory. When AQI values are above 100, air quality is unhealthy
Fine particulate matter PM2.5 are fine inhalable particles of size 2.5 micrometers and smaller, they are dangerous to human health as they can go into lungs and bloodstream. Particles from smokeless heating fuels, road dust, combustion particles, organic compounds, mold, large bacteria etc.
Particulate Matter PM 10 are inhalable particles, with diameters that are generally 10 micrometers and smaller. It includes dust, pollen, pet dander, smoke, gaseous pollutants, etc.
These are extremely fine particulate matter (PM) particles of diameter less than 1 micron — significantly smaller than PM 2.5. These can measure the lowest finer particles of the particulate matter including microorganisms like bacteria, fungus and other organic compounds.
Carbon di Oxide in indoors go higher with more people occupy confined space, poor ventilation, combustion by products. When carbon dioxide levels spike, it increases the likelihood of health issues like sleepiness, distraction, lethargy and affecting productivity, concentration, and work performance.
VOCs, volatile organic compounds, are cancer-causing gas chemicals released by products or processes. they can react with other gases and form other air pollutants after they are in the air. Total volatile organic compounds (TVOC) is a group of VOCs used to represent the entire pool of pollutants.
Formaldehyde (CH2O) is a naturally occurring organic compound, a chemical that is used in building materials and to produce many household products. The dangerous gas is commonly emitted by wooden painted surfaces, fabrics, carpets, adhesives & glues in furniture, and building materials like pressed wood & particle board.
Uniformity of temperature is important to comfort and wellbeing. Improper temperature in the indoor is a serious risk for your health and can cause insufficient humidity. Maintaining the proper temperature for the indoors is very critical to maintain healthy indoor air quality.
Humidity level is just as important as the indoor temperature. Humidity affects comfort, overall health, and the air quality. When the humidity threshold is breached it enhances the growth of Bacteria, Viruses Mold spores, dust mites and other allergens that cause respiratory infections.
Dew Point is critically important to the end result of the Air Quality. Dew point is focused primarily on temperature and relative humidity. It refers to the dew point temperature of a gas under pressure. This is important because changing the pressure of a gas changes the dew point temperature of the gas.
