PM2.5 (Particulate Matter 2.5) refers to fine particles with diameter of 2.5
micrometers or less. Due to its tiny size, PM2.5 can be absorbed into
bloodstream and the lungs, which may cause eye and nose irritation, cough,
asthma, emphysema, lung disease, heart attacks, cancer and etc.
Temperature & Humidity may often be ignored however they do have a significant
impact on 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 electricity and etc.
AQI (Air Quality Index) is a quick guide showing how clean or polluted the air is,
using a range from 0 to 500, where higher index values indicate higher levels of
air pollution and higher risks to health. There are six pollutants for AQI in US
standard: PM2.5/10, O3, SO2, NO2, CO, where Temtop only focus on PM2.5/10
and follows the US EPA Standards to compute AQI.
