Indoor Allergies

Dust / Mould

Indoor allergies such as dust and mould are common. Read below to find out more about what causes these types of allergies and how you can help manage them.

Dust and dust mite allergy

We can’t see them, but dust mites live amongst us. They are microscopic spider-like insects that are found all over the house, clinging to fabric, upholstery, bed linens, pillows and mattresses. The most common cause of indoor allergies is dust mites.

These insects, invisible to the human eye, live strictly indoors. They feast on the millions of dead skin cells that we shed from our bodies every single day. House dust is made up of many particles – fabric fibers, bacteria and dust mites.

As with all triggers, recognising them as the cause of your symptoms will help you to customise your management strategies for indoor allergens and allergic reactions to dust.

Tips for handling dust mites

Textiles

Minimize carpeting. Hard-surface flooring throughout your home is preferable.

Invest in technology

You can purchase specially made mattress and pillow protectors which guard against the mites.

Cleaning products to manage allergies

Clean regularly

Regularly clean, dust with a damp cloth, and wait for dust to settle before you vacuum.

Prepare

Wash sheets and blankets in hot water at least once a week to help reduce dust levels.

Prevent

Install a HEPA filter for air filtration and use a HEPA filter vacuum cleaner to filter out dust mites that live in your home.

Establish a routine

Professional steam cleaning of carpets is an effective way to reduce indoor allergens. It’s best to do this as part of your spring cleaning routine, before the start of allergy season.

Mould allergy

Although we usually associate hay fever allergy symptoms with plants and pollen, spores released by mould can often be a hidden enemy and can cause similar symptoms to hay fever. Mould is a common allergen found naturally outdoors, but it can also seep into your home in areas that are damp. The growth of mould tends to peak in late summer and run right until the autumn, depending on the dampness of the location.

The tiny, airborne spores of mould that cause allergic reactions may be found either indoors or outdoors and will grow in either setting if the breeding conditions are right: damp and dark is what they like. Recognising an indoor mould allergy is the first step to managing it. By eliminating the source of the mould you may solve the problem altogether.

Tips for reducing indoor mould

Air quality

Keep humidity levels low with air conditioners and dehumidifiers.

Textiles

Avoid carpets and rugs in your home. If you do have some, low pile is best and steam clean them regularly.

HEPA filter to help manage allergies

Invest in technology

Mould spores are exceptionally tiny and not readily trapped by standard air filters. To reduce airborne mould spores, install a HEPA air filter. It is capable of trapping air particles such as pollen, dust mites, mould, and pet dander through a fine filter. It can significantly reduce airborne particulate matter and indoor allergens in your home.

Prepare

When vacuuming, sweeping, or doing other housework around the house, you can kick up a lot of mould and dust build-up. Wear a mask to reduce your exposure. For hard-surfaced floors, sweep first, and then dampen them to minimize the dust floating in the air. Use re-usable micro-fiber cleaning cloths.

Prevent

Use cleaning solutions designed to kill mould and mildew.

Monitor

Check your home for visible leaks or moisture. Mould has a distinctive smell that may tip you off to a growth area. Check bathrooms, furnace rooms – any area that is poorly ventilated, dark, and has the potential to be damp – as they are breeding grounds for mould.
