What is the best air filter for old homes?
If you live in an old house, the indoor air quality issues may be different from those found in a modern home. Unless a great deal of refurbishment or rebuilding has been done, older home has less insulation and more cracks in the walls, doors and windows. Therefore, damp and accompanying mould spores may be an important element in indoor pollution as well as a constant influx of traffic-related pollution. So what is the best air purifier for old homes?
In the modern home, with its energy efficient insulation, indoor air pollutant of a different kind are more likely to build up – because of lack of ventilation (modern houses are often compared to living in a plastic bag) – increasing exposure to a mixture of pollutants including Volatile Organic Compounds, such as formaldehyde, tobacco smoke (if smoking is allowed) and nitrogen dioxides from gas appliances. People in very modern buildings, whether home or office, may experience a cluster of symptoms known as Sick Building Syndrome (SBS). The symptoms of this poorly understood condition range from chronic fatigue and headache to a sore throat and lack of concentration. Buildings both old and new are also permeable to pollution coming in from outside, such as pollen grains and particles from traffic exhaust – the latter being a particular problem if you live near a busy road or a large city.
Whatever the age of your house and the type of indoor air pollution you are exposed to, the use of a proper air purifier will improve the air quality in the building and can significantly reduce any symptoms you may experience. There are two main types of air purifier:
So, if you live in an old home, first tackle the sources of indoor air pollution – like damp, or products that give off formaldehyde (such as foam-backed carpet) – and then consider which is the right air purifier for you. The model you choose will depend upon the pollutants you need to get rid of and on the size and number of rooms where the air needs to be cleaned. A good unit for the removal of mould is the Blueair range of air purifiers, which use ionisation in combination with a particle filter. If you are not sure about the exact type of pollution you want to remove, or you would like to remove a broad range of airborne pollution, we recommend the IQAir rage of air purifiers. The IQAir air purifier's medical filtration will virtually take all particle pollution out of the air and also provides best in class filtration for chemicals, odours and gases.
