5 worst home allergens: how to get clean air indoors
How clean is the air in your home? Wayne Anderson from shares the 5 worst allergens found in Australian homes.

Allergic responses like those to pollen or animal dander are the most common types of health problems related to mould. Related: How to remove mould and mildew
2. Cats and dogs. Animal allergens adhere to fur and other surfaces and can be dispersed into the environment as animals shed hair and dander and secrete and excrete fluids. Indoors the allergens accumulate on household furnishings including carpets, upholstery, mattresses, curtains and other textiles.

5. Cockroaches. Cockroach allergens come from droppings, called frass. The allergens tend to be heavy, similar to dust mite allergen, and are only likely to be airborne with activities such as sweeping or vacuuming – so it’s best to fix the pest problem rather than clean the mess. The airborne cockroach particles enter the mucous membranes of the eyes, nose, and lungs, and are known to cause or worsen various allergic diseases such as allergic rhinitis and asthma.
