When air sits for an extended period in a room or area with no circulation or ventilation, it becomes stale. Stale air is no longer fresh and often carries an odour or feels stuffy. This is unpleasant in any season.

Stale air may harbour contaminants that have no chance of escaping. It is a good idea to address this issue quickly as stale air may indicate that a room is retaining moisture in walls, ceilings, or floors. If untreated, this can cause mould and mildew, and subsequently lead to health issues.

There are various ways that indoor air quality can be improved, which can help manage the health of everyone in the home or office. Here are some tips to help remove stale air and keep indoor air quality at its best.

Run the heat pump / air conditioner
Heat pump / air conditioning allows you to control temperature and assist with humidity levels. Fujitsu General units offer ‘dry mode’ function. In dry mode, the fan operates at a low speed drawing air through the heat pump / air conditioning unit to remove humidity (moisture). Fujitsu General’s wall mounted split systems also include an apple-catechin filter which captures fine dust, invisible mould spores and harmful microorganisms that are absorbed onto the filter. It is highly recommended that you maintain your unit by keeping the filters clean and the heat pump /air conditioning system periodically serviced every one to two years depending on usage by a licenced technician.

Open doors and windows
When the heat pump / air conditioning system is off, a simple way to improve the indoor air quality is to open doors and windows to let the air circulate. By moving the stale air you are replacing the oxygen and avoiding mould growth by reducing condensation.

Cleaning up
Staying on top of household cleaning can be difficult, but it can significantly help to avoid stale air and the potential health risks. Carpets and rugs can harbour chemicals and allergens such as dust mites, some of which can become airborne. Dusting and vacuuming regularly will help to minimise these circulating around the home. Additionally, wiping down benches and bathrooms can remove mould spores that may impair your air quality.
