Why we need to remove formaldehyde from home after renovation works

Formaldehyde is one of the Volatile organic compounds (VOCs) which is dangerous to human health. Formaldehyde is typically not acutely toxic, but instead have compounding long-term health effects. A major source of man-made VOCs are coatings, especially paints and protective coatings.


Allergy is a hypersensitivity disorder of the immune system. Allergic reactions occur to normally harmless environmental substances known as allergens; these reactions are acquired, predictable, and rapid. Strictly, allergy is one of four forms of hypersensitivity and is called type I (or immediate) hypersensitivity. It is characterized by excessive activation of certain white blood cells called mast cells and basophils by a type of antibody known as IgE, resulting in an extreme inflammatory response.

Asthma and Allergy

Some main signs of allergy are itchiness, sneezing, inflamed or infected eczema, watering/reddening eyes, runny nose and clogging in the lungs. Allergens that triggers of asthma can hide in the most unlikely places like on air conditioners. This is why regular air conditioner cleaning is vital.

IgE and Asthma

Immunoglobulin E, or IgE, is a natural substance in your body that plays an important role in the development of allergic asthma. Increased levels of IgE may result when you are exposed to triggers, such as:

  • Animal dander
  • Dust mites
  • Molds

When you're exposed to certain allergens, your body releases IgE, which then binds with several types of cells:

  • Basophils
  • Lymphocytes
  • Mast cells

When IgE binds with any of these cells, it can stimulate your immune system, cause your airways to become narrow and inflamed, and make your asthma symptoms worse.
