How wool interiors can help clean the air in your home

Wool is a complex, natural fibre. Bringing many specific benefits to a wide variety of different products.

But, did you know that choosing wool interior products, such as carpets, can actually help to remove potentially harmful chemicals from your home?

Scientific research indicates that having wool carpets, curtains and soft furnishings could improve the quality of air inside homes and offices. All thanks to the amazing qualities of wool fibre.


Volatile organic compounds (VOCs) are present items or substances, that we use daily in our homes including; cleaning fragrances, paint, glue and furniture.

A number of of these, including formaldehyde, are now recognised as known carcinogens.

And are also associated with ‘sick building syndrome’, where people living or working within a particular building, and results in them experiencing headaches and allergic reactions. All because of the environment around them.

How does wool absorb VOCs?

A team from Bangor University carried out research to assess the ability of wool to absorb harmful chemicals. The team exposed wool to a range of VOCs, emitted by furniture made from MDF and chipboard, limonene, found in cleaning products, and toluene, found in paint thinners. The results demonstrated that wool absorbed all of the chemicals, which became bound to the structure of the fibres.

Graham Ormondroyd, Head of Materials Research at Bangor University said: “The research demonstrated that wool, a natural and sustainable material. Is able to absorb a range of potentially harmful chemicals from the indoor environment. The more wool you have the more it can absorb.”

Wool can also helps to manage humidity in the air. By storing the excess moisture in the core of the fibre and then releasing it when the air is drier. This important benefit supports clean air, as rising moisture levels create a breeding ground for mould. Which could later develop into “toxic mould syndrome”.

Amongst other benefits, wool carpets can also help prevent pet odours, another reason to choose them for the family home.
