How air purifiers can help reduce allergens at home
A well-sealed home isn’t necessarily a pollutant free home. Some improvements in home sealing can actual hinder pollutants from leaving our indoor space. In fact, the air inside our homes can be up to five times more polluted than the air outside1. As Australians tend to spend almost 80%2 of time indoors, air quality can be a larger determinant of our daily wellbeing.
Our homes can contain many different airborne allergens, including pollen, pet dander, dust mites, mould spores and organic compounds. When there is a high concentration of pollen in the home, this can affect our respiratory health and common skin conditions such as eczema3.
To reduce these potential symptoms, air purifiers for allergies can provide efficient exposure and removal of airborne allergens. Below, we’ll discuss how effective air purification can help alleviate allergies in your home.

Each air purifier has two core components, a quality fine thread filter and a fan. The fan continuously draws in various pollutants and the filters remove or reduce pollutants, to be replaced with purified air.
The best air purifiers for allergies can clean pollutants and particles as small as 0.1 microns. This capability can be attributed to their HEPA filters containing multi-layer strands that work efficiently to improve air quality.
HEPA air purifiers and activated carbon filters are designed to trap and extract microscopic as small as 0.1 microns4. Making them proficient at removing bacteria, viruses, organic compounds and allergens

How do air purifiers help allergies?
Indoor air quality is paramount for a healthy home environment. Cleaner air can help support our breathing habits, as well as provide relief for allergy sufferers. Below we’ve listed the different ways that air purifiers can help with different allergy symptoms.
Air purifiers for pollen allergies
If you’re experiencing a constant runny nose, sneezing or congestion – you be triggered by allergies throughout the seasons. Millions of people fall under this bracket – with pollen allergies being more commonly referred to as hay fever.
These uncomfortable symptoms can be heightened during spring and summer, when, due to the reproductive cycles of plants, trees and grasses, more pollen is released into the atmosphere. Pollen is a fine powdery substance – which can easily breeze through the home if not monitored. While we often want to open our windows to clean the air indoors, it can actually result in more pollen entering your home.
Keeping windows closed and using an air purifier with a HEPA filter can help to capture ultrafine dust and allergen particles.
Air purifiers for pet allergies
Our pets remain members of the family, and while they bring joy – they can also bring pet dander and pollen into the home. For some people, cuddling or even patting can lead to sneezing and watery eyes, and in some cases, coughing or wheezing. It’s estimated that 20% of people around the world experience these signs of pet dander allergies5.
An ideal solution for dealing with such pet allergens is an air purifier, which can help remove particles as small as 0.1 microns. An air purifier like the Dyson Purifier Big+Quiet™ Formaldehyde can work to capture 99.95% of ultrafine particles6, as well as destroy signs of formaldehyde for enhanced air quality in the home.
Air purifiers for dust allergies
Dust mites in the home can provoke allergic reactions and may enhance symptoms for asthma sufferers. Air purifiers for allergies can capture the smallest particles to reduce dust in the home, as well as improve purified airflow.
An allergic response to dust mites can disrupt a good night’s sleep and can also occur during bed making. By placing an air purifier in the bedroom with the ‘Night mode’ featured turned on – this can help to trap allergens in the air before they have a chance to settle.
