Formaldehyde, CH2O is a colorless volatile organic compound with a strong odor. There are two main sources of it: off-gassing and combustion. Formaldehyde is presented outdoors, but its concentrations indoors are higher due to its emission prevalence in building materials and household products.

Temperature & Humidity
Generally, people feel comfortable at temperatures between 21°C to 27°C (69°F to 80°F).
Generally, people feel comfortable at a relative humidity between 40% to 60%.

Light intensity
Light intensity requirements depend on the space's specific purposes. The light levels for a conference room or a library should be 300-500 lux (30-50 fc), while professional laboratories require 750-1200 lux (75-120 fc). Workspaces and spaces for the elderly people need more than 500 lux (46 fc). In the evening hours, light intensity should be as low as 5 lux (0,46 fc) to eliminate sleep disruption.
Atmospheric Pressure
Noise
Noise levels above 70 dB over a prolonged time period may start to damage your hearing.
PM1, PM2.5, PM10
PM1 are ultrafine particles with a diameter smaller than 1 micrometer: dust, combustion particles, bacteria. PM2.5 can be made of different chemicals like black carbon, ammonia, sulfur dioxide, etc. PM10 or coarse dust particles refer to particles with a diameter less than or equal to 10 microns in size. They are about 30 times smaller than the width of human hair and are small enough to get inhaled into our lungs.

TVOC
Total Volatile Organic Compounds metric is the total concentration of volatile organic compounds in the air. VOCs are carbon-containing chemical gases emitted from solids and liquids. VOCs are not only hazardous but also play a significant role in the formation of ozone and fine particulates (PM) in the atmosphere.
Light Intensity
CO2
Carbon dioxide is an odorless non-toxic gas. People exhale CO2 when they breathe. When there are several people in a poorly ventilated room, CO2 concentration increases and affects occupants’ wellbeing. Safe standards for indoors: 400-1000 ppm.
Atmospheric pressure
When barometric pressure drops, your blood pressure decreases. For some, this can mean dizziness or even blurred vision. Also some people experience high-altitude headaches due to changes in barometric pressure, such as during plane travel.
