believes that poor indoor air quality can result in a range of undesirable health effects as well as a reduction in life years.

risk of heart disease and stroke, while people with asthma may experience worse symptoms if they have an allergic reaction to a pollutant in the air. In addition, university researcher Professor Hazim Awbi8

Air purification

With all the risk factors previously discussed in mind, it is clear why organisations are increasingly talking about poor indoor air quality and are taking steps to counter it. Once you have read the statistics, suddenly measures such as air cleaning are no longer seen as a luxury, they become a necessity. One of the most popular ways of tackling poor indoor air quality is through the use of air purifiers, which are recommended by a range of professional bodies such as the Environmental Protection Agency9

in the US and consumer rights group Which? .10,11 They

are recommended for improving air quality by cleaning the air, capturing polluting particles such as dust, smoke and pollen and removing them from the air. Air purifiers literally clean the air. For example, the use of HEPA filters and a four-stage purification system can remove up to 99.97 per cent of airborne contaminants from 0.1 microns in size, leaving the air cleaner and healthier and providing worry-free air purification. They remove airborne germs and viruses – including flu and the norovirus – as well as allergens and pollen, particulate matter and odour. This can make a care home a cleaner, healthier, fresher and more pleasant place to live, work and visit. Air purifiers show immediate results. When you install an air purifier, it measures the level of contaminants in the air. As it gets to work, you can see the levels improving as the pollutants are removed and replaced with clean air. This means that residents are immediately breathing air that is cleaner and healthier, protecting them from the risk of pollution and reducing exposure to germs that

cause colds and flu as well as allergens such as pollen.


There has been a rise in demand for air cleaning across many different sectors, but particularly within healthcare. The aim is to improve air quality, thereby protecting people from pollutants and contaminants. Air purifiers can provide an effective solution to indoor air pollution, making a real difference to the quality of the air. With all the evidence pointing this way, air cleaning simply becomes common sense.
