Wool carpets are the healthiest choice for floor covering. Wool doesn’t give off toxins known as Volatile Organic Compounds, which are released from synthetic fibers. It is also non-allergenic and does not encourage growth of bacteria or dust mites. Wool rugs work as filters for dust, pollen, and spores keeping the air in your room as fresh as possible. You can even place your wool rug in the sunlight where the UV rays will kill any dust mites without any chemical products or treatments.
