Why we need to clean air conditioner
Air conditioners can be excellent allergens (i.e. mold, yeast) & bacteria breading grounds. Dust gets deposited on the cooling fins, then becomes damp because air conditioners condense water out of the air. Damp dust is a pretty good medium for growing mold and bacteria. Cleaning your air conditioners regularly can improve your health and the efficiency of the machines.
Allergy
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.
