Many everyday activities in your home such as dusting, vacuuming, cooking, smoking, cleaning and burning an open fire or wood stove can increase concentrations of airborne particles and chemicals. Because many modern houses are now virtually draft free it means that there is very little circulation of air. The particles and vapours that build up can seriously affect your health particularly if you suffer from hay fever, asthma, rhinitis, eczema or multiple chemical sensitivity. The pollution levels found in many modern homes can be several times higher than the pollution level found on a busy road.
An air purifier can make a huge difference to you by improving the air quality in your indoor environment and reducing the pollution load on you and your family.
Room Size and Air Changes Per Hour
At The Healthy House we recommend that the air in the room be changed at least 3 times an hour, and assuming a standard ceiling height of 2.2 metres. This gives a good level of cleaning and will keep up with the normal flow of air into and out of a room. If the room has high traffic or there are doors and windows that are continuously being opened and closed you may decide to have a larger unit or use a higher fan speed during high traffic times. You may find that the size of room a unit is recommended for on our website is smaller than the size claimed on the box.
