Indoor Air Quality And Allergy

Allergic Asthma

Allergic asthma is the most common type of asthma. About 90% of kids with childhood asthma have allergies, compared with about 50% of adults. Inhaling specific substances called allergens (allergy triggers, such as pollen, mites, or molds) brings on the asthma symptoms associated with allergic asthma.

Nearly everyone with asthma (allergic or non-allergic) gets worse after exercising in cold air or after inhaling any type of smoke, dust, fumes, and sometimes strong smells.

Allergens, which are small enough to be inhaled deep into the lungs, include:

Windblown pollen from trees, grasses, and weeds
Mold spores and mold fragments
Animal dander (from hair, skin, or feathers) and saliva
Dust mite feces
Cockroach feces
Allergens are not the only thing that can worsen your allergic asthma. Irritants may still trigger an asthma attack, even though they don't cause an allergic reaction. Irritants that you inhale may also trigger an asthma attack. These irritants include:

Tobacco smoke
Smoke from a fireplace, candles, incense, or fireworks
Strong chemical odors or fumes
Perfumes, air fresheners, or other scented products
Dusty workplaces


Allergic Rhinitis

Allergic rhinitis is an allergic reaction that happens when your immune system overreacts to substances that you have inhaled, such as pollen. The two types of allergic rhinitis are seasonal allergic rhinitis (hay fever) and perennial allergic rhinitis, which occurs year-round. Hay fever is caused by outdoor allergens. Perennial allergic rhinitis is caused by indoor allergens such as dust mites, pet dander, and mold.


When you breathe in an allergen, your immune system springs into action. It releases substances known as IgEs into your nasal passages, along with inflammatory chemicals such as histamines. Your nose, sinuses, or eyes may become itchy and congested. Scientists aren't sure what causes your immune system to overreact to an allergen.

Allergic rhinitis affects 20 percent to 25 percent of people in Canada and up to 75 percent of people with asthma.

The best way to reduce symptoms is to prevent exposure to allergens.


Atopic Dermatitis (Eczema)

Atopic dermatitis is a chronic inflammation of the surface layer of the skin, frequently associated with a personal or family history of related allergic disorders such as hayfever or asthma.

Constant itching, scratching or rubbing lead to an itch-scratch cycle. In older children and adults, atopic dermatitis typically appears as redness, swelling and scaling/thickening in elbow creases, the back of the knee, and on eyelids, neck and wrists.

Although the actual cause of atopic dermatitis is unknown, triggers include irritants (such as soap, laundry detergent), emotional stress, environmental temperature changes or humidity changes, bacterial skin infections, and wool garments.


There is significant evidence, however, that airborne allergens such as dust mites, cat dander, and cockroaches play an important role in atopic dermatitis.
For example, researcher Deuell examined the level of mite allergen exposure from mattresses and bedroom carpets in a series of 51 pediatric patients with atopic dermatitis. He found that the majority of these patients were exposed to high levels of mite allergens in their homes. Eighty percent had positive skin tests to dust mite.

Indoor allergens (especially dust mite, cat dander and cockroaches) are airborne and therefore come into contact with the skin. These allergens are becoming a focus of research attention as significant triggers of atopic dermatitis



Good Air Purification Treatment will fully sanitize and disinfect, deodorize and eradicate smoke odors, pet dander, dust mites, bedbugs, cockroaches, bacteria, viruses and most all other allergens, VOCs and noxious odors, living or not that might be deeply imbedded in carpets, furniture, mattresses, behind walls, under sinks, in cabinets and in drawers.
