Airborne Allergens: What to Know?
How are surfaces important in controlling airborne allergens? How do you tell the difference between colds and allergies? We're glad you asked. Find all this and more.
What is an Airborne Allergen?
An airborne allergen is something that causes an allergic response, such as itching and sneezing. Someone who does not have an allergy can be exposed to exactly the same substance, such as pet dander, and not have any response at all.
Common Indoor Allergens
Inside our homes, the most common allergens include:
- Dust Mite Debris
- Pet Dander
- Mould Spores
- Pollen
Dust mites, pet dander and mould spores are often present in our homes, so are called ‘indoor allergens’. We usually think of pollen as being an ‘outdoor allergen’, but during the warmer months pollen often readily enters our homes in the air, through open windows and doors, and on people’s hair and clothing.
These allergens can float through the air from where they can be inhaled or enter the eyes causing symptoms. They can also land on surfaces. If the surfaces are disturbed, the allergens on them can disperse into the air again.
