Wool breathes - it's warm in the winter, and cool in the summer.
Wool is hypoallergenic (really!) - allergy triggering bacteria, mould and mildew don't thrive in wool like other materials
It helps clean indoor air - it has the ability to absorb harmful pollutants from the air, and doesn't re-emit them. It's estimated that wool used in interiors can help purify the air for 30 years.
Prevents dust mites - wool's breathability and ability to change with ambient temperature doesn't make a good place for the growth and breeding of the house dust mite. Dust mite allergens are one of the triggers for asthma attacks.
Naturally antistatic - Static attracts lint, dirt, and dust. Wool's anti-static properties keep it much cleaner for longer.
Easy cleaning - wool fabrics clean easily because the outside surface of the wool fibre consists of a series of overlapping scales (similar to the feathers on a bird), which means that dirt sits on the surface of the fibre, making it easy to remove.
Naturally flame resistant - wool's difficult to ignite, making flame spread extremely low and can self extinguish and doesn't melt like petroleum based or chemically treated materials.
Naturally renewable -Sheep grow wool just by existing and need to be shorn every year. Wool is so unique that we still haven't been able to replicate it yet.
Compostable and biodegradable - wool will naturally biodegrade, just ask any shepherd. Sheep have been losing wool on the landscape for thousands of years. If it didn't biodegrade, we'd live in a very wooly world indeed.
