Preventing damage by air contaminants
Wool is is bio-degradable — the natural ability of pure wool to biodegrade is an asset to the world as the eco agenda grows .
Wool is durable — unique resilience ensures that it can withstand wear and tear over a long period .

Non-allergenic

Additionally , wool does not promote the growth of bacteria or dust mites . The fibres are too long and coarse to be inhaled and so will not irritate the respiratory system or trigger an allergic response .

Preventing damage by air contaminants

The way wool purifies the internal atmosphere can be vital and is due to the acid-combining potential of wool . It absorbs and holds onto volatile organic compounds ( VOCs ). These are invisible chemical pollutants which linger in the air . Wool does not emit VOCs and even absorbs certain harmful VOCs , holding them within its core permanently .
This is the case for formaldehyde , nitrogen dioxide and sulphur dioxide , which wool can remove from the air by absorption and will not release even when heated . Wool can purify indoor air for up to 30 years , thus preventing the potential of serious contamination . �
Did you know …? Following the installation of wool in five buildings that had formaldehyde concentrations above the World Health organisation ’ s recommended level of 0.05ppm , German researchers recorded that the level in all five had dropped below that level within 24 hours .
