WOOL IMPROVES INDOOR AIR QUALITY
Breathing is a really good life skill. So maybe we should consider the quality of the air we breathe when we decorate our homes and offices. Installing laminates and plastics won’t help you if you suffer from Asthma or other respiratory problems.
The build-up of indoor air contaminants has been a growing concern since the 1970’s. It was then that energy conservation methods were introduced, which minimized the flow of outside air into homes and buildings. Less access to outside air increases the concentration of contaminants in an indoor space, making the air unhealthy…even toxic.
Although many materials, including carpet, pass tests for minimum VOC emissions, wool goes a giant step further by absorbing the contaminants irreversibly in its structure, improving the quality of indoor air.
Wool is a natural fibre that has the ability to absorb indoor contaminants, including formaldehyde, sulphur-dioxide and nitrogen dioxide, and lock them into its core without re-releasing them. As such, wool improves indoor air and creates healthier working and living environments.
How Wool Works
The complex chemistry of wool fibre enables it to bind pollutant gases chemically in its structure. It has been estimated that wool carpets can continue purifying indoor air for up to 30 years.
New Zealand researchers, using a controlled environmental chamber, have demonstrated that wool carpet can reduce high levels of introduced formaldehyde to virtually zero in four (4) hours.
Studies by the US Gas Research Institute, which compared 35 building and furnishing materials, also showed that wool carpets have one of the highest removal rates of nitrogen dioxide. In contrast, the removal rate of synthetic carpets was less than half that of wool.
Research by the Environmental and Medical Sciences Division of the UK Atomic Energy Research Establishment has shown that large amounts of sulphur-dioxide are also irreversibly absorbed by wool carpets.
Wool carpet was shown to retain the gases when heated, as would occur with under-floor central heating, while nylon carpet, which absorbed nitrogen dioxide to a considerably lesser extent, also re-emitted it more readily
Wool is a highly complex fibre that has been created by nature over thousands of years. It is simply not possible to get the benefits of wool from a fibre designed by man and made from crude oil.
