How air purifiers can help reduce allergens in your home

Air purifiers can improve air quality and circulate clean air. By trapping mould spores and odours, and removing particles including airborne irritants, they can be effective at removing the source of allergens.

It’s worth noting that the benefits will be affected by the air purifier’s specifications and filter type.

If you’re one of the millions of people who suffer from pollen allergies, you’ll likely experience sneezing, congestion, a runny rose, and other uncomfortable symptoms as allergy season arrives.

Pollen is a fine powder made up of tiny particles. It’s released during the early spring and summer months by plants, trees and grasses as part of their reproductive cycle. Pollen causes a common allergic reaction known as hay fever, which since it occurs at particular times of the year, is also known as seasonal rhinitis.

Rather than opening windows on warm days, try using an air purifier to clean your indoor air, keep you cool, and capture ultrafine dust and allergens. Using an air purifier with a HEPA filter between March and September will help remove pollen allergens from the air you breathe.

Our furry friends can bring plenty of joy, but also a few microscopic surprises into the home, including pet dander, pollen, and viruses. What’s more, you may find that cuddling your pet leaves you sneezing, coughing or rubbing your eyes. It’s estimated that pet dander allergies affect up to 20% of people around the world.⁵

It’s possible to remove the particles that trigger allergies caused by pets using a good air purifier. Approximately 75% of cat dander particles are 5-10 microns in size, and 25% are 2.5 microns or smaller.⁶

Dust mites can be a major indoor trigger for people with allergies and asthma. Fortunately, an air purifier effectively removes dust, including dust mite allergens, and can help you breathe easier.

Most exposure to dust mite allergens occurs while sleeping and when dust is disturbed during bed-making. An air purifier in your bedroom can help trap these allergens before they have a chance to settle.

Allergies can be uncomfortable, but using a HEPA air purifier can help trap pollutants and reduce airborne allergens – giving you and your family cleaner indoor air.
