“Protect your family from exposing to harmful chemicals used at home”. Numerous toxic chemicals are present in every household. It could be the factors of having all the accidental poisonings , asthma or allergies in your family. Home + Green Cleaning™ adopts non-toxic cleaners to remove harmful contaminants (allergens, bacteria, viruses etc.) and at the same time sterilizes & cleans the areas being treated.
Air conditioners can be excellent breeding grounds for microorganisms (i.e. moulds, yeasts, bacteria) in relation to allergies. Dust stuck on the cooling fins, then become damp because the air conditioners would condense water out of the air. Damp dust is prone to moulds and bacteria growth. Cleaning your air conditioners regularly can improve your family health, keeping your family away from allergy, and improve the efficiency of the air-conditioners.
Indoor air has been known to be 2 – 5 times as contaminated as outdoor air in some places. Having an air filter does not mean the air quality of your home is perfect. Allergens like formaldehyde, respirable suspended particulates, pollens, dust mites, moulds, bacteria, fungi or even volatile chemicals from conventional cleaners can accumulate in your air conditioners, curtains, mattresses, sofas and carpets, pollutes the air you are breathing in.
Some water filtered vacuums which have been proven (with the help of Laser Particle Counter) to be able to dissolve allergen, then emit them (including ‘fine’ to less than 0.3µm in size ‘ultra-fine’ particles) through a mist into the air during vacuuming. Fine and ultra-fine particles are present in greater numbers and have greater surface area than larger particles of the same mass, and they are generally considered to be more harmful. The emission will also increase the chance and lengthen the survival time of bacteria and viruses etc.
Particulate matter (PM) is a complex mixture of solid and liquid particles that suspend in the air. These particles typically consist of a mixture of inorganic and organic chemicals, including carbon, sulfates, nitrates, metals, acids, and other semi-volatile compounds.
The size of PM lingering in air ranges from approximately 0.005 to 100 micrometers (µm) in diameter – range from the size of just a few atoms, to somewhat the thickness of a human hair. Researchers have defined size categories for these particles differently. For the purposes of this fact sheet, PM is defined by three general categories commonly used by the U.S. Environmental Protection Agency (U.S. EPA): coarse (10 to 2.5 µm), fine (2.5 µm or smaller), and ultra-fine (0.1 µm or smaller).
Research suggests that particle size is an important factor that affect how the particles deposit into the respiratory tract and affect human health. Coarse particles are deposited almost exclusively in the nose and throat; whereas, fine and ultra-fine particles generally are able to penetrate to deep areas of the lung. Fine and ultrafine particles are present in greater numbers and have greater surface area than larger particles of the same mass, and they are generally considered to be more toxic.
The health effects of PM are likely to depend on several factors, including the size and composition of the particles, the level and duration of exposure, and age and sensitivity of the exposed person. Symptoms of exposure may include a sore throat, persistent cough, eye irritation, wheezing, shortness of breath, tightness of chest, and chest pain. PM may also trigger asthma or may lead to premature death, particularly in the elderly who have preexisting cardiovascular and respiratory diseases.
In order to reduce house dust mite allergens in the environment, we need to reduce the growth of the mites as well as remove the allergens themselves. As mite growth depends on humidity, reducing the relative humidity to below 50% for 5 days can kill the mites.
House dust mites
The droppings of house dust mites contain high levels of allergens. These allergens have enzymatic activities and will penetrate protective layers of the skin as well as mucous membrane. For people who are allergic to dust mites, exposure to these allergens will lead to allergic reaction. In fact, house dust mites are considered the most common allergens at home.
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 are tiny and light perfect for taking wing in the ducts and open air of spaces around your house. Allergens produced by house dust mites are among the most common triggers of asthma.
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 and moulds. When you’re exposed to certain allergens, your body releases IgE, which then binds with several types of cells like basophils, lymphocytes & mast cells. This can then stimulate your immune system, cause your airways to become narrow and inflamed, and make your asthma symptoms worse.
Immediate Type Allergic Reactions
Type I (immediate type) allergic reactions are mediated by the IgE antibody. Low levels of immunoglobulin circulate in the blood stream as the majority is bound to the surface of mast cells and basophil granulocytes.
The binding of allergen epitopes to specific IgE antibodies, located on the surfaces of granulocytes, triggers the immediate release of pro-inflammatory mediators (histamine, enzyme, cytokines) which cause allergic symptoms.
