Air purifier for asthma and allergies

About two-thirds of those with asthma and various forms of allergies state that their symptoms get worse when air quality gets worse. The reason is that the air pollutants can irritate the airways and trigger, for example, asthma symptoms. The smaller particles reach all the way down into the lung and gases can pass further into the bloodstream.

Some of the most common gases are nitrogen dioxide and ozone, which i.a. comes from the traffic. These gases can trigger asthma as they are very irritating to the airways and lungs. It is well known that ozone is directly related to asthma attacks. Ozone can reduce lung function and make it harder to breathe.

WHO writes in its Housing and Health Guidelines that bad indoor air has a number of harmful health effects. Air pollution is associated with allergies, weakened immune systems, cancer, skin, eye, nose and throat irritation. Air pollution can also adversely affect the reproductive, nervous and cardiovascular systems.

They also write that minimizing air pollution is important to obtain an acceptable indoor air quality.

Air pollution in Swedish cities such as Malmö, Gothenburg and Stockholm

Even in cities such as Malmö, Gothenburg and Stockholm, it turns out that air pollution is so obvious that it can cause serious damage. A study by Stefan Hansson, chief physician at the Women’s Clinic in Lund, showed that harmful particles from air pollution enter the cells of the placenta and cause inflammation in pregnant women and that these women at contaminated addresses were twice as affected.

In Skåne alone, 780 people die each year and 117 children develop asthma and 59 bronchitis for the same reason.

Air purifier to combat asthma and allergies

The indoor air often contains higher concentrations of air pollutants than the outdoor air as emissions from pets, pollen, mold, electronics, dust mites and cleaning products are added to the air pollutants that come from outside and together they create a cocktail effect that makes it up to 50 times more harmful to inhale than the outdoor air.

One way to counteract asthma and allergies is to minimize indoor air from these harmful air pollutants is to use a high quality air purifier with both particulate filters such as a HEPA H13 filter and carbon filters that can trap gases such as nitrogen dioxide and ozone.

But it must be an air purifier with documented capacity and real HEPA filters, says one of the world’s foremost researchers on air pollution, Dr. Kari Nadeau Director at the Sean N. Parker Center for Allergy and Asthma Research at Stanford University.
