Why wool?

"Wool contributes to a healthier environment by helping to remove allergens and pollutants from the air. Because wool is hypo-allergenic it deters the growth of dust mites.

Wool temporarily traps dust and allergens that can exasperate asthma and respiratory conditions. Dust from our living environments is removed by the fibres of wool which temporarily ensnares pollutants and allergens, ensuring that particles are not re-circulated and re-released, unless vacuumed and cleaned by washing.”
