Air Purifiers and Respiratory Conditions


Respiratory conditions can come with a wide range of unpleasant symptoms. Unfortunately, they are also very easy to exacerbate. Contaminants in the air can lead to respiratory conditions, but they can also cause them to flare up. For this reason, people with respiratory problems are in need of pure air to ensure that their condition does not worsen. More often than not, those with respiratory conditions turn to air purifiers to provide them with a safe and clean air supply that will not aggravate their condition. Choosing the right purifier can help to improve health for those in need.

What Common Respiratory Conditions Benefit from Air Purifiers?

Emphysema and chronic bronchitis come under the term of Chronic obstructive pulmonary disease (COPD). It has become the fourth leading cause of death in united states and sometimes it can be asymptomatic. (meaning you will never know that if you are suffering from this disease unless you visit a doctor or severe symptoms appear).

COPD is a lung disease that can block airflow and restrict breathing. Structural alterations in lung result in chronic (more than 3 months) inflammation due to repeated exposure of noxious gases and particles such as cigarette smoke. This inflammation triggered by smoking can persist for many months resulting in narrowing of airways and reduction in lung recoil(1).

Most common symptoms of chronic obstructive pulmonary disease are dyspnea, sputum, cough and it can even lead to respiratory failure(1).

Asthma is another most frequently occurring disease, “from a very mild, occasional wheeze to acute, life-threatening airway closure”. Additional features of asthma include hay fever and eczema(2-4).

Asthma leads to hospital admissions and places a great load on an individual due to medical expenditures. The characteristic finding of this disease is airway hyper-responsiveness triggered by numerous factors like exposure to inflammatory gases, tobacco smoke and particulate matter. If left untreated, asthma can be  fatal.

For this reason, air purifiers are important and can help to reduce unpleasant wheezing and coughing. Asthma is a condition that can vary in severity and results in difficulty breathing. It is known for its discomfort and is very easy to aggravate with poor air quality. Air purifiers can remove pet dander, allergens, and chemicals that would otherwise make asthma worse, or make sufferers more prone to asthma attacks.

 How air purifiers work, and why each air purifier is recommended for respiratory conditions.

An air purifier cleanses indoor air in several steps:

  • Contains a pre-filter that eliminates macro particles, such as pollen, dust and pet hair
  • A medical grade HEPA filter filters out “99.97% of fine airborne particles that are greater than 0.3 microns.
  • The deep-bed activated carbon filter adsorbs airborne odor, gases and chemicals.
  • These filters trap and attract chemicals like formaldehyde, volatile organic compounds, benzene via their tiny fissures and pores.
  • Similarly, an activated carbon sponge surface is able to absorb more chemical compounds and gases. And this capacity of the sponge is highly depending upon sponge depth and size.
  • The absorbing power of an air purifier depends upon activated carbon presence.

Air purifiers eases breathing difficulties via provision of clean and pure air because your stressed-out airways do not have to undergo further stresses as air purifiers will clean and filter out chemicals and particulate matter from the air. However, the medical treatment is vital as your lungs and airway will already be damaged.

Similarly, in case of Asthma, air purifiers will prevent asthma attacks by removal of allergens, chemicals, pet dander, and smoke. Asthma attacks are mostly triggered by these things. That’s the basic reason for the application of air purifiers and further details about each purifier recommendation is explained with product descriptions as each purifier has different properties.

Additional tips for relief from Asthma and Chronic Obstructive Pulmonary Disease (COPD)

For Asthma

Asthma is trigger specific disease; it highly depends upon its cause. For example, if cigarette smoking, pet dander, rodents, cockroaches are the source, you need to avoid or eliminate these sources.

  • Don’t go outdoors, if air is polluted or there is smoke from cigarettes or wildfire
  • Keep your home clean, clean electronic devices, furniture etc. to prevent dust from accumulating
  • A Vacuum cleaner should be used to remove dust particles if available
  • If dust mites are the problem, use a mattress cover that aid in containing these dust mites or for removal.
  • Go for a skin allergy test, your doctor will determine which trigger is the root cause of wheezing. Try to avoid this allergen.
  • If smoking is the trigger, avoid the areas where people smoke.


  • The one of the simplest solutions for COPD is keep everything “clean, clean and clean”.
  • “Don’t allow smoking indoors at all,” zero smoking!
  • Maintain adequate ventilation in your kitchen
  • Minimize the use of carpets in your home
  • Avoid pets
  • Keep humidity level below 50 percent in your home. For this purpose, turn your bathroom fan on high.
  • Clean furniture and other surfaces regularly via using vinegar, lemon and methyl spirited liquids and combine this with boiling water.
  • Do not purchase products with volatile organic compounds. Before buying products, you should check the ingredient list.
  • Use your vacuum cleaner
  • While going outdoors use a N95 face mask, which prevents exposure to most small particles (usually up to 95 percent).

What triggers wheezing?

  • Formaldehyde is found in large number of products like cleaning agents, cosmetics, carpets, furniture and wallpaper. Research has shown that formaldehyde triggers wheezing symptom.
  • Volatile organic compounds including single and mixed components(5) and fragrances (6)can cause wheezing.
  • Greater Carbon dioxide exposure can also result in wheezing(5).
  • Excessive exposure with stoves, ovens, fireplaces and water heater containing nitrous oxide can also trigger wheezing.

The Best Air Purifiers for Respiratory Conditions

Choosing an air purifier with robust carbon filters to remove gases, chemicals and volatile organic compounds that irritate your lungs is important. Many air purifiers filter out gases like nitrogen dioxide (NO2), which is known for playing a role in coughing and wheezing. By removing this from the air, it is easier for sufferers to find relief. Many people do not realize how big of a role air quality can play.  In addition, HEPA filters are important for removing smaller particles floating in the air that can cause coughing and wheezing.
