HCHO

Pollution Sources: Paint and construction materials include blankets, insulation, wood-based products, floors finishes and other decoration materials. Bacteria spread through ventilation systems, live in the air, and thrive in humid and poorly ventilated places.

O₃

Pollution Sources: Air purifiers, printerss, fax machines, computers...etc. Bacteria spread through ventilation systems, live in the air, and thrive in humid and poorly ventilated places.

Health effects: Stimulates and damages the deep respiratory tract, can damage the central nervous system, and has a mild irritating effect on the eyes; hinders blood oxygen delivery, causing body tissue hypoxia; impairs thyroid function, calcifies bones, and can cause potential body systemic effects, Such as induced lymphocyte chromosomal aberrations.

CO₂

Pollution Sources: 瓦斯、香菸、煤炭、蚊香等不完全燃燒現象。另外，汽車排放進入室內。

Health effects: 頭痛、頭暈、噁心、嘔吐、疲勞、虛弱，嚴重者視網膜出血、損害心臟及中樞系統、胎兒畸形等。

PM_2.5

Pollution Sources: Ammonium sulfate, nitrate, other gaseous pollutants and motor vehicle exhaust, etc., in addition, printer toner is also a source of pollution. Bacteria spread through ventilation systems, live in the air, and thrive in humid and poorly ventilated places.

Health effects: Harmful to the respiratory tract, including the mouth, nose, pharynx, larynx, bronchial areas and alveolar areas. May causes shortness of breath, chest tightness, inflammation, allergies and other symptoms, leading to diseases such as night lung disease, asbestosis, anemia, infertility, etc.

Fungi , Bacteria

Pollution Sources: Fungi often attach to the surface of indoor objects, such as clothing, leather, furniture, devices, home appliances and other surfaces to grow and multiply. Bacteria spread through ventilation systems, live in the air, and thrive in humid and poorly ventilated places.

Health effects: Respiratory allergy symptoms, mild nasal congestion, runny nose, sneezing, severe breathing difficulties, wheezing. Once the disease occur, it’s often unhealed over years. It can cause nasal polyps, emphysema, and pulmonary heart disease over time.
