The recommended level of indoor humidity is in the range of 30–60% in air conditioned buildings, [34] [35] but new standards such as the adaptive model allow lower and higher humidity, depending on the other factors involved in thermal comfort. Recently, the effects of low relative humidity and high air velocity were tested on humans after ...
Much has been made about the dangerous pandemic pathogens flying around the air outside of our personal bubbles this year, but in the cold months ahead, the safety of indoor locations may be a ...
The US Occupational Safety and Health Administration recommends indoor air be maintained at 20–24.5 °C (68–76 °F) with a 20–60% relative humidity, [13] equivalent to a dew point of approximately 4.0 to 16.5 °C (39 to 62 °F) (by Simple Rule calculation below).
When measuring environmental data from the Building Automation System, sensor placement must align with the recommended criteria for physical measurements. Temperature sensors should achieve an accuracy of ±0.5 °C (±1 °F) and humidity sensors ±5% relative humidity. The trending capabilities require data to be recorded at intervals of no ...
The Levoit Duual 200S Smart Humidifier is a compact and reasonably priced mister that can help maintain comfortable humidity levels in your home.
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. [2] Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest.
The World Health Organization in 1987 found that comfortable indoor temperatures of 18–24 °C (64–75 °F) were not associated with health risks for healthy adults with appropriate clothing, humidity, and other factors. For infants, elderly, and those with significant health problems, a minimum of 20 °C (68 °F) was recommended.
Mold growth can be inhibited by keeping surfaces at conditions that are further from condensation, with relative humidity levels below 75%. This usually translates to a relative humidity of indoor air below 60%, in agreement with the guidelines for thermal comfort that recommend a relative humidity between 40 - 60 %.
