Asthma & Allergies
As most asthma or allergy sufferers will know, the common house dust mite can play a major part in aggravating their symptoms.
The house dust mite
Dust mites have 8 legs and are related to the spider. You are probably sharing your bed with thousands of them!
Their main breeding ground is in bedding and carpets. They feed on microscopic scales of skin, which we all shed. Their only source of water is from the air, so they prefer to live in areas where relative humidity is high. The higher the humidity, the quicker they are able to breed.
The dust mite has been attributed with the increase in asthma (now affecting 20% of New Zealanders , equivalent to a staggering 1 in 5 households) plus other bronchial and skin problems.
So how do we get rid of dust mites ?
No matter how clean our home is, dust mites cannot be totally eliminated. However, to live and breed, dust mites require the following:
- Microscopic scales of skin shed by humans and pets
- A continuous supply of humid air
If there are high levels of relative humidity in an occupied dwelling then you will find a breeding ground for dust mites. The quickest and most effective way in reducing the population of dust mites in a home is by reducing relative humidity by providing adequate ventilation.
Main trigger for asthma and allergies
Dust mites and their droppings are known allergens. When their rotting carcasses and droppings come into contact with our skin or are inhaled they may cause an allergic reaction.
Researchers estimate that these particles may be a trigger for up to 80% of asthma attacks and responsible for countless causes of eczema.
Improving indoor air quality with NHS Sefton
In a recent Sefton Council project set up to support families with children suffering from asthma, EnviroVent units were chosen to be installed in sixteen homes to improve indoor air quality and dust allergies. After the units had been installed questionnaires were sent out to the families to monitor the effectiveness of the units.
The results were overwhelming. The majority of families involved in the project experienced positive improvements in the health of their children and in the indoor air quality. Not only that, all the problems with mould and condensation had disappeared.
