Asthma and Allergens

What is Asthma?

Asthma is a disease of the airways, the small tubes which carry air in and out of the lungs. When your asthma is triggered the muscles in the airways tighten and the lining of the airways swells, causing the airways to become narrow so that there is less space for the air to flow into and out of your lungs.

Symptoms can include:

  • Symptoms can include
  • Coughing
  • Tight feeling in the chest
  • Wheezing – whistling noise when breathing
  • Shortness of breath
  • Struggling to breathe

Dust Mites

Like moderate temperatures and high humidity. They are found in bedding, flooring and furniture.


Our furry friends are the most common cause of pet allergies. They shed hair daily.


Enters the house on clothing and shoes, so regular cleaning is the best way to reduce pollen in your home.


Is mostly found in houses with rising damp and poorly ventilated areas, such as bathrooms or built-in robes.

Get the Facts

Over 2 million Australians have asthma – and about one in three of them suffer from allergies.

Allergens, e.g. house dust mites, pollens, pets and moulds are one of the most common triggers for asthma.

The best prevention of allergens triggers is reducing your exposure to them.

Filtration in Bosch

The HEPA filters used in all Bosch vacuums are at the highest level ranging from HEPA 12 - HEPA 14. All Bosch bagless and bagged vacuums are fitted with a HEPA filter to ensure at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter are absorbed.

Due to this filtration level that the HEPA and motor filter within the Bosch vacuum achieves, combined with the high power motor the air that is expelled from the vacuum is actually cleaner than the current air we breathe.

Bosch motors use efficient air movement within the vacuum to maintain strong airflow at all times. The vacuum’s air tight seals ensure that no air can escape nor is the air misguided throughout its movement within its filtration path before being expelled.

Sensor bagless technology – an included feature within the Bosch bagless range, maintains a full dust separation system to ensure the filtration level is maximized without clogging. It also alerts you when the airflow drops within a 10% range below optimal performance level to remind you to clean the filters and maintain your vacuum cleaner functioning at its highest cleaning performance level.
