‘Fine dust’ refers to inhalable dust from the particulate dust that floats or blows in the air. Fine dust and ultrafine dust are categorized according to the diameter of the dust. Fine dust (PM10) is dust with a particle diameter of less than 10㎛. It not only causes lung diseases but also reduces your body’s immune system and causes skin, eye, or respiratory system diseases, so you have to manage fine dust with a proper prevention method to protect your health.
Carbon dioxide used as a key indicator of indoor pollution
Carbon dioxide is a colorless, tasteless gas with little toxicity in the gas itself, but in large quantities. Increased breathing speed can lead to breathing disorders, headaches, tinnitus, and elevated blood pressure caused by inhalation of many harmful gases. Carbon dioxide in the room is usually generated when a person comes out of the breathing process, or when heating or cooking. It is influenced by indoor volume, indoor number of people, heating status, and ventilation, so it is used as a major indicator of indoor pollution.
The Whiparang Portable Fine Dust Measuring Device can conveniently measure PM2.5 ultrafine dust / PM10 fine dust / temperature / humidity at the same time with the laser sensor anytime, anywhere in real-time.
