Air Purifiers for Asthma Patients

Asthma can be triggered by various pollutants in the indoor air. In addition to classic allergens such as animal hair or pollen, viruses and bacteria can also be the cause. Therefore, for asthma patients, air purifiers with particularly fine filters or sterilization functions are suitable.
How do air purifiers improve asthma symptoms and which types of air purifiers work best for asthma? This article will help you decide which device is right for you.

What is the impact of air quality on asthma?

Asthma is a chronic respiratory disease in which the immune system overreacts strongly to certain environmental influences. Typical symptoms are increased mucus secretion in the bronchi, which leads to narrowing of the airways and thus shortness of breath. The causes and manifestations of asthma are very diverse, so it is difficult to study the effectiveness of countermeasures, such as purifying certain components of the air.

Which air pollutants cause asthma?

In general, two forms of asthma can be distinguished: allergic asthma, which has extrinsic causes and is triggered by an increased concentration of certain allergens in the air. On the other hand, intrinsic, non-allergic asthma is usually attributed to respiratory infections or drug intolerance.
Allergic asthma can be triggered by a variety of allergens in indoor air: these include animal hair, pollen, dust mites and their excrement, and mold. On the other hand, it is not the classic allergens, but viruses and bacteria in the air we breathe that are often responsible for the development of non-allergic asthma. All asthma patients are also particularly sensitive to other air pollutants, especially tobacco smoke and ozone.

Which air purifiers help prevent asthma?

While all air purifiers suitable for allergy sufferers can be used to treat allergic asthma, the bactericidal effect should also be considered for non-allergic asthma.

Particle filters for asthma sufferers

To reduce the concentration of allergens in the air, fine particle filters help to filter out animal hair, indoor dust and pollen. HEPA filters are particularly suitable for asthma sufferers. HEPA filter stands for High Efficiency Particulate Air filter and is the name of an air purifier that can filter out suspended particles up to 0.1 μm. Depending on the model, more than 99.9% of the air is free of pollutants and allergens.
Activated carbon filters for asthma sufferers are also available as additional filters. These are particularly effective against organic chemicals in the air. This is particularly interesting for asthma patients, whose disease is mainly caused by increased irritation in professional work environments, such as paint and paint fumes.

Effectiveness of air purifiers for asthma

How effective air purifiers are in combating the symptoms of asthma patients remains controversial in the literature: despite the large number of studies, methodological flaws or lack of objective comparability are the most common reasons why the results can only be interpreted with caution. It can be clearly shown that air purifiers can reduce the number of allergens in the air, especially through particularly effective HEPA filters. However, in many cases there is no direct evidence that this also relieves asthma symptoms. In addition to the large number of different manifestations of the asthma disease, the wide variety of possible air purifiers may also be responsible for this.
As a recommendation for asthma patients, many scientists conclude that particularly effective air filtration seems to be necessary to achieve a clear improvement in symptoms. It is best to purify the air in the bedroom, since you spend most of your time there and a small amount of air can pass through the air purifier more frequently. Models that work very quietly are ideal.
The effect of environmental humidity on asthma relief

High or low humidity has different effects on the human body and germs

To the human body
Too low humidity:
When the humidity in the air is lower than 45%, it will cause dryness in the room, leading to dryness of the skin, throat, and respiratory tract, and easily
causing respiratory diseases such as asthma. When the air humidity is higher than 60%, the human body will feel stuffy and unbearable.
Too high humidity:
When the air humidity is higher than 80%, it is considered too high humidity, which will make it difficult for the human body to dissipate heat, resulting in symptoms such as high body temperature, rapid heartbeat, dizziness and nausea.
To germs:
When the air humidity is higher than 65% or lower than 38%, germs reproduce fastest; when the relative humidity is between 45% and55%, the mortality rate of germs is relatively high.
Choose a suitable humidifier to maintain the indoor humidity at 45%~65%. It is necessary not only to filter but also to relieve respiratory discomfort caused by dryness. The thermal distillation humidifier has a humidification capacity of up to 1200ML/H, which is 6 times faster than the traditional ultrasonic humidifier. The warm mist water molecule density is small, and it diffuses faster, farther and more evenly. It is designed for people with health sensitivity.
