While there have been numerous conversations around the potentially harmful effects that carpets have on an indoor environment, studies prove that this is, in fact, untrue. Carpets are breathable, balance humidity levels and offer sound reduction.
In addition, carpets promote lower allergy levels. It is true that carpets are capable of trapping soil dust and pet or insect residue that may trigger allergic reactions in some people. But just because allergens may be present in the carpet does not mean that they pose a hazard to human health. An allergen must be inhaled for exposure to occur, and to be inhaled, it must be airborne. Careful measurements show that allergen particles are relatively heavy and difficult to get into the air, and fall quickly after becoming airborne.
Studies show that a carpet acts like a filter, trapping allergens and keeping them out of the breathing zone until they can be removed through proper vacuuming.
Wool carpets also emit no Volatile Organic Compounds (VOCs), but actually absorb them from surrounding material and furnishing, and permanently lock these within the fibres, protecting humans from these hazardous gases.
