+ Green Cleaning™ is created by the Johnson Group. We have hand-selected the best quality materials and equipment to help you to eliminate dirt, stains, moulds and bacteria. “Protect people from exposing to the harmful chemicals used in indoor”. The introduction of + Green Cleaning™ is part of the Johnson Group’s efforts to educate public especially kids about the benefits of natural or non-toxic cleaners in daily cleaning, and encourage their interest in protecting environments. We believe a balanced ecosystem will benefit all living organisms, in particular, the human.

Why do We Need to Deep Clean and Sanitize Office

Indoor air has been shown to be 2-5 times as contaminated as outdoor air in some places? Having an air filter doesn’t mean your indoor air quality is perfect. Indoor allergens like formaldehyde, dust mites, mould, particles or even volatile chemicals from conventional cleaners can accumulate in air conditioners, curtains, mattresses, sofas and carpets to make the air you’re breathing more polluted than ever. The best way to reduce this type of indoor air pollution is switch to non-toxic services and products like our deep cleaning and natural ingredient cleaners.

We don’t recommend DIY cleaning with water filtered vacuums

Some water filtered vacuums which have been proven (with the help of Laser Particle Counter) to dissolve allergen, then emit them (including fine and less than 0.3µm in sizeultrafine particles) through a mist into the air during vacuuming. 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 emission will also increase the chance and lengthen the survival time of bacteria and viruses etc.

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 indoor.


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.
