Do Air Purifiers Help to Prevent Respiratory Diseases?

Air purifiers have been around for quite some time and there are literally thousands of models available in the market right now. Some of you may be interested in getting one for your home. Before buying an air purifier, it is important to do your research and consider the reason why you are buying one. The main purpose of air purifiers is to filter out air pollution in an area, which can lead to diseases and allergies. If you live in an area with bad air quality, an air purifier may be a particularly good investment.

Some clinical studies have shown that air purifiers may help prevent respiratory diseases. However, most clinical studies only deal with short term data, meaning that more studies need to be done to examine the effectiveness of air purifiers in the longer run. The results that we currently have right now, however, are quite optimistic. Most studies have shown that air purifiers can contribute to preventing respiratory diseases. The effectiveness mostly depends on the kind of respiratory diseases that are being suffered.

Air Pollution

Air pollution is one of the most common problems in highly urbanized cities and areas these days. Our modern society has made strides in being aware of the effects it has on the environment, but as it is, we still have a long way to go. In fact, it is estimated by the World Health Organization (WHO), that air pollution is one of the biggest environmental health risks which is connected to several million deaths per year.

Air pollution can cause many different types of respiratory diseases. One of the most common is allergies. Poor air quality can also trigger asthma in people who already have the disease. Take note that air pollution does not only refer to dust and smoke. It can also refer to objects that are pleasant but can become sources of air pollution such as scented candles or pets.

Purpose of a Purifier

What an air purifier does is to remove the irritants and pollutants in your home in order to stop them from causing havoc to your respiratory system. Most air purifiers have filters that can remove these irritants and pollutants, leading to improved air quality inside the room. Most air purifiers also deal with a variety of pollutants such as pet hair or dander, pollen, dust, and smoke.

In choosing an air purifier, it is helpful to choose one which has a HEPA filter. HEPA stands for High-Efficiency Particulate Air. An air purifier with a HEPA filter captures 99.7% of airborne particles down to 0.3 microns in diameter. Through this process of removing contaminants, HEPA can improve air quality and reduce the chances of respiratory diseases.

Common RESPIRATORY Diseases


Air purifiers can help people suffering from asthma. Asthma is a very common disease, with millions suffering from it annually. Most of the time it manifests during childhood. There is currently no cure for the disease, but asthmatic patients can help reduce attacks with the use of an air purifier. An air purifier helps remove the irritants which could trigger an asthma attack. While an air purifier is not a hundred percent assurance that asthma attacks will be gone, it can help improve the lives and conditions of asthmatic people.


COPD refers to Chronic Obstructive Pulmonary Disease. It is a term that refers to a wide variety of different but related illnesses. Manifestations of COPD include difficulty in breathing and may include illnesses such as bronchitis and emphysema. The American Lung Association estimates that COPD is the third largest killer in the US. Air purifiers can reduce the onset of COPD by removing irritants and pollutants from the air.


Air purifiers can be very helpful in preventing respiratory diseases by removing irritants and pollutants from the air. Improved air quality has also been linked to an improvement in cardiovascular health. By removing the airborne toxins and triggers, air purifiers can help prevent the onset of respiratory diseases, or at least reduce the possibility of attacks in those with pre-existing conditions.
