What are VOC's?
Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products numbering in the thousands. G2Clean's VOC sensor directly measures ambient concentrations of a broad range of VOCs associated with bad air quality. Examples are: alcohols, aldehydes, ketones, organic acids, amines, organic chloramines, aliphatic and aromatic hydrocarbons. These gases all burn and cause the VOC sensor ppm output to increase.
Ventilation and Climate Control: Increasing the amount of fresh air in your home
will help reduce the concentration of VOCs indoors.
1. Increase ventilation by opening doors, windows, or dampers.
2. Keep both the temperature and relative humidity as low as possible or comfortable. HEPA filters will do a great job of capturing particles, but not the VOCs. To also remove formaldehyde and other VOCs, (chemical off-gassing) you will need an air purifier with additional technology. Air purifiers with plain activated carbon or granulated carbon are not as effective in removing VOCs.
As mold “consumes” its food, the chemical reactions of enzymes, substrates and mold growth produce carbon dioxide, water, and volatile organic compounds (VOC). ... When you smell a “musty-moldy” odor, it's generally the VOC you are noticing.
What are PM2.5's?
Fine particulate matter (PM2.5) is an air pollutant that is a concern for people’s health when levels in air are high. PM2.5 are tiny particles in the air that reduce visibility and cause the air to appear hazy when elevated. Dust, spores and pollen are some examples. PM2. 5 refers to particles that have diameter less than 2.5 micrometers (more than 100 times thinner than a human hair) and remain suspended in the air for long periods of time. These particles are formed as a result of burning fuel and chemical reactions that take place in the atmosphere.
Why Humidity Matters
The recommended average relative humidity for your indoors is 30 to 50%, when the outside temperature is 20°F or more. If the indoor relative humidity is above 60%, mold and mildew begin to form and these can pose quite a problem to the health of the building's occupants.
According to OSHA, humidity is one of the biggest contributing factors to poor indoor air quality. High indoor humidity can be a catalyst for mold and mildew growth. It can also facilitate perfect growing environments for bacteria and viruses, which can cause respiratory diseases and infections.
Concerns about CO2
Carbon Dioxide (CO2) is a relatively easy to measure surrogate for indoor pollutants emitted by humans, and correlates with human metabolic activity. Carbon dioxide at levels that are unusually high indoors may cause occupants to grow drowsy, to get headaches, or to function at lower activity levels. Humans are the main source of carbon dioxide in most buildings. Indoor CO2 levels are an indicator of the adequacy of outdoor air ventilation relative to indoor occupant density and metabolic activity.
The Basis for Our Standards
Our team, having a strong understanding of indoor air quality pollution from material off-gasing, realized that there was a need for ways to better understand indoor air quality. Due to the high variability of air quality and its tendency to quickly change, we believed that continuous air quality monitoring will become a necessity for indoor spaces. As we explored indoor air quality monitoring, we realized that there were no standards around how to monitor nor what specification requirements there should be for the actual monitors themselves.
