Carpet Tile and Indoor Air Quality

Start with the sources of indoor air pollution

A floor is one part of indoor air quality. Product emissions, dust tracked through entrances, cleaning products, ventilation and moisture all matter. Carpet can hold settled particles until they are removed by cleaning; it can also accumulate dust when maintenance is poor. The choice between carpet and a hard floor therefore cannot be reduced to a claim that one surface always has cleaner air.

The US EPA's guidance for schools describes carpet as a potential reservoir for dust and other materials, and explains why regular vacuuming, suitable filtration, moisture control and periodic cleaning matter. It also describes a carpet-emissions testing programme. Apply the same questions to a commercial interior, with a maintenance frequency set for its actual traffic and soil load.

Choose a product with identifiable emissions information

Ask which exact carpet tile, backing, adhesive and any underlay will be installed. Request current emissions information for the relevant products and check that the documents cover the proposed construction. A logo on a brochure or the absence of odour is not a measurement of room air quality.

Ventilation and other materials also influence the completed room. The EPA's indoor particulate guide recommends cleaning and ventilation to reduce dust and suggests suitable vacuum filtration. Plan how the space will be ventilated during installation and cleaned in use.

Build the maintenance plan around the room

• Put walk-off soil control at the entrance and assign responsibility for its cleaning.
• Vacuum carpet and furnishings at a frequency appropriate to traffic; inspect busy routes more often.
• Use the selected product's spot and deep-cleaning instructions, and prevent moisture from remaining in or beneath the floor.
• Keep the exact product, emissions documents, installation record and maintenance guidance with the handover pack.
