Carbon dioxide(CO2) is a colorless and odorless gas usually derived
from the breath of humans and animals. High CO2concentration
means that fresh air or ventilation is required; otherwise, it may
cause problems such as drowsiness, dizziness, loss of attention,
and cognitive impairment.
Temperature &Humidity may often be ignored. However, they do have
a significant impact on an individual's well-being, comfort, health
and safety, as well as your property. High Humidity may lead to an
increase in household air pollutants, especially the biological contaminants
such as molds, bacteria, viruses, and dust mites; cold, low Humidity
may cause nosebleeds, skin and respiratory irritations, dyspnea, static
