    We’re more aware than ever of the health implications of maintaining a clean home. But what about house dust mites?

    ‘Household dust can be a concern, as it may contain allergens such as dust mite faeces and pollen,’ Gem explains. ‘Mattresses, bedding, upholstery and carpets can all accumulate unseen dust’.

    House dust mites feed on moulds, as well as animal and human skin flakes. They flourish in textiles all around our homes.

    Gem adds, ‘All of our research has shown that the best way to deal with bacteria, pollen and dust mite allergens is to remove them from your home completely.’

    1. Vacuum mattresses

    Do this task on a regular basis. Why? ‘To remove dust mite allergen and skin flakes which dust mites feed on,’ Gem advises. ‘Vacuum both sides of the mattress with a vacuum cleaner with an advanced filtration to prevent the allergen being placed back into the room by exhaust air.’

    2. Wash bedding on a hot wash

    The hotter the better to destroy allergens. ‘Washing the bedding on a 60°C or 90°C wash will help to break down allergen (proteins) and reduce the amount to cause allergies,’ says Gem.

    3. Wash or replace duvets and pillows

    This act can help to reduce the amount of dust-mite allergens and skin flakes present in your bed. A grim thought, but true, sadly.

    4. Remove dust from kitchen cupboard tops

    This is an often overlooked place. Yet dust collects here and can be displaced into the kitchen through air movement. Either remove the dust with a vacuum that has an advanced filtration system, or wipe the cupboard tops down with a clean damp cloth or cleaning wipes.

    5. Dust with a damp cloth

    ‘When dusting either use a damp cloth or cleaning wipes,’ says Gem. ‘These trap the dust more easily. Or use a vacuum with an advanced filtration system that will effectively collect and trap the dust. A vacuum cleaner with different attachments and suction is ideal for dust round your home.

    6. Vacuum your home after dusting

    Following around with a vacuum cleaner ensures you get every last bit. ‘Any dust that has been disturbed and placed onto the floor is removed and not redistributed around the home by normal activity,’ Gem explains.

    7. Move furniture

    Don’t just clean the bits you can reach with ease. ‘Move furniture that can be moved and vacuum the places not often vacuumed, such as under the furniture.’

    8. Vacuum sofas and chairs regularly

    Not just inviting to us, these comfy accessories can welcome unwanted visitors, too. Gem explains how sofas and armchairs, ‘harbour not only large debris but also dust mites, skin flakes and other allergens such as pollen and food allergens.’ The advice? ‘Wash any coverings and cushions to reduce the level of dust caught within them.’

    9. Clean the curtains

    ‘A lot of dust can gather in curtains and blinds. Be sure to vacuum them regularly or launder them if possible and practical.’

    10. Remove dust from walls

    ‘By dusting with a damp cloth or cleaning wipes or using a HEPA filtered vacuum.’ We forget about the walls, but here’s why we shouldn’t… ‘Dust on certain wall types can contribute toward the growth of mould’ gem explains. ‘If the room is humid and not well ventilated the dust can act as the nutrient source for the growing mould.’ Yuck!

    11. Empty kitchen sides and cupboards to deep clean

    Gem says, ‘Use a vacuum with advanced filtration to remove dust and debris. Then wash with warm water and detergent – make sure you follow up by drying all surfaces.’

    12. Dust lights

    ‘A lot of dust can gather in lampshades and light fittings which can burn on hot bulbs producing VOCs (Volatile Organic Compounds). Odour can also be moved round the room by the production of warm air round the bulbs.’

    13. Empty the fridge and freezer

    ‘Clean all surfaces with warm water and detergent or cleaning product. Vacuum round the back and under the fridge and freezer, without forgetting the cooler element on the back. This will have the added benefit of improved performance.’

    14. Dust behind radiators

    So often missed during normal everyday cleaning. ‘Significant dust collects behind the radiator and this can be distributed round the room by the air flow produced by the warm air from the radiator.’

    ‘The radiator is not hot enough to prevent bacteria from surviving and can be maintained viable in the dust contained behind the radiator.’

    15. Deep clean bedroom storage

    This includes all cupboards, wardrobes, and drawers in the bedroom. ‘This is a place rarely emptied and cleaned but dust and fibres can accumulate in the very place you keep your clean clothes. Dust mites can live anywhere there is a source of food; so wherever there is dust, there is the possibility of dust mites.’
