For those that suffer from Chronic Obstructive Pulmonary Disease, or COPD, you know how important it is to make sure the air you breathe is as clean as possible. However, not everyone with COPD understands how air purifiers can help to improve your COPD symptoms and the transformation it can make in your quality of life. With the ability to make a real difference for those that suffer from COPD, it can create a safe and livable environment in your home. Here are a few tips and reviews to help you find the best air purifier for COPD.

COPD is a term used to describe a group of progressive lung diseases, such as chronic bronchitis and emphysema. An individual with COPD suffers from a reduction in the flow of air to the lungs, making it hard to breathe. As COPD progresses, breathing becomes more painful over time. Some common symptoms include wheezing, a chronic cough, and shortness of breath. The damage caused by these progressive lung diseases is irreversible.

Although COPD is incurable, many individuals find some relief via oral steroids or steroids that are inhaled. Others utilize rescue inhalers. Whichever course is prescribed, with proper treatment, a person with COPD can experience relief from their symptoms, and any additional damage to their lungs can be minimized. In fact, with the right diagnosis and treatment, individuals can live for many years with COPD.

A progressive lung disease, COPD partially blocks your airways making it more painful to breathe over time. COPD cause two common diseases that can also happen together:

  • Chronic bronchitis – With inflammation of the tubes inside your lungs, chronic bronchitis can lead to wheezing, fluid buildup, and coughing.
  • Emphysema – Often associated with an increase in wheezing and coughing, emphysema causes reduced breathing.

More than 12 million people in America have COPD, and since this is a progressive disease, many people aren’t aware that they have it until they notice the symptoms. Early intervention is important, so if you think you have COPD, you should see your doctor right away for diagnosis and management.

Common in smokers and anyone that has had exposure to secondhand smoke, COPD can also be caused a genetic predisposition to diseases like emphysema, multiple respiratory infections, and exposure to air pollutants.

How Can an Air Purifier Help COPD?

Not a substitute for standard medical treatment, an air purifier can help make the air around your more bearable. Particles like allergens, dander, chemicals, pollen, and dust can make breathing difficult and painful when you have narrow airways. When you have reduced capacity in your lungs, they can become stressed from irritations or chemicals making it more difficult to breathe.

Filtered air can be very important when managing your COPD symptoms. By removing airborne irritants, all these pollutants can be removed before they irritate your lungs and contribute to your breathing difficulties. Prevention is important when staying healthy, so it can help to put an air purifier in every room of your home to prevent lung and airway damage.

How Air Purifiers Work

The technology used in an air purifier is rather simple and straight forward. Air purifiers utilize internal fans that draw the air within the room into a combination of filters within the air purifier. The filters are designed to remove a variety of airborne particles, such as allergens, dust, and pollen. Once the air passes through the filters, the air purifier then recirculates the purified air back into the room. Air purifiers continue with this process as long as the system is turned on, resulting in cleaner and healthier air that is much easier to breath because it has been purified.

Choosing the Best Air Purifiers for COPD Patients

Typically, you should look for an air purifier that is 99 percent efficient, uses a HEPA filter, and can filter out particles that are as small as .03 microns. It is even better if you can find a machine that will filter particles that are .01 microns or smaller. If you happen to live with a smoker, look for a machine that can filter out both odors and chemicals that are associated with cigarette smoke. Filters that use activated carbon means that they can remove airborne odors and chemicals that cause irritation for those that suffer from COPD.

Types of filters that help to manage COPD

While there are a variety of filters used in air purifiers, it is recommended that individuals with COPD choose one that has a HEPA filter. HEPA filters are effective because of their capability of filtering particles as tiny as .03 microns at 99 percent efficiency. In fact, some HEPA filters can even filter particles as small as .01 microns.

For individuals that are exposed to secondhand smoke, it is recommended that they choose an air purifier that–in addition to having a HEPA filter–can also filter odors and chemicals that accompany smoking. In the case of secondhand smoke, an individual should look for an air purifier that includes activated carbon. This type of filter is designed to remove the chemicals and odors in the air that are known to cause excess irritation in individuals with COPD.

What to look for in an air purifier

  • Filter type: Perhaps the most important feature to consider is the filter. As previously discussed, it is highly recommended that individuals choose an air purifier that utilizes a HEPA filter. The incredible filtering power of a HEPA filter can make a significant impact on an individual’s ability to breathe and provide him or her a noticeable improvement in breathing comfort.

    Additionally, it is important to consider the minimum efficiency reporting value (MERV) rating. A rating between 11 and 13 is generally thought to be a good choice. However, the higher the number, the better the unit.

  • Types of particles targeted: In addition to choosing an air purifier that contains a HEPA filter, you should also look for an air purifier that specifically targets particles that are known to cause problem in individuals that suffer from COPD.
    • volatile organic compounds (VOCs)
    • allergens
    • chemicals
  • Activated carbon: Air purifiers that include activated carbon provide an extra layer of defense for individuals with COPD because activated carbon is extremely effective at filtering chemicals from the air. This is because when the carbon comes in contact with, for instance, VOCs, a reaction occurs that is natural and safe, resulting in the VOCs sticking to the filter instead of returning to the air in the room.
  • Noise: Because some air purifiers run more quietly than others, it is important to consider the noise level. For instance, some air purifiers are so quiet that users might need to check if the unit is, in fact, on. While this might be a selling point for some, others might need some sort of noise, such as white noise, to help them sleep soundly.

Air Purifiers and COPD

Many people think that shortness of breath and other difficulties in breathing are an inevitable and even normal part of aging. However, in many cases, this is simply not true. Unfortunately, it is quite common for individuals to ignore signs that they may be experiencing a serious illness.

For instance, individuals experiencing shortness of breath or a chronic cough might ignore these symptoms because they do not realize they might be suffering from Chronic Obstructive Pulmonary Disease (COPD). In fact, it is important to visit your doctor if you are experiencing any difficulty in breathing as this is not a normal part of aging.

COPD is a very serious disease that causes irreversible lung damage, and it should be noted that using an air purifier instead of seeking medical treatment is not an acceptable form of treatment. That said, using an air purifier in conjunction with proper medical treatment can help make the simple act of breathing a lot more tolerable.

To understand why an air purifier can provide relief for a person with COPD, it is important to first understand that healthy lungs are very efficient at filtering out airborne particles that regularly find their way into the respiratory system. Some common airborne particles that the lungs must address daily include pet dander, dust, and allergens. Pollen and chemicals are some other common particles that must be filtered out by the lungs so as to not interfere with breathing

However, because individuals with COPD suffer from narrowing airways, their lungs experience great difficulty with this, and common airborne particles tend to end up getting trapped in the airways, making breathing difficult as well as painful. Because of this, breathing air that does not contain these common airborne particles is a vital component in the successful management of the symptoms associated with COPD.
