Second Studio's wool absorbs contaminants in the air, improving the indoor air quality and helping you breathe easier. Not only does their wool keep the air free of many pollutants, it will not re-emit them, even when heated. In fact, it has been estimated that Second Studio's wool rugs can continually purify indoor air for up to 30 years. Also, their wool fiber does not support combustion - it is difficult to ignite and is self-extinguishable. Charring can be easily brushed away. As well as being extremely safe, their wool carpets retain their appearance even after minor burn damage from fireplace embers or cigarettes. Hand-Tufted. 100% Pure Wool. Various Sizes & Colors.
