What Causes a COPD Flare-up?

COPD refers to a number of chronic inflammatory lung conditions, such as asthma, emphysema, and chronic bronchitis.

These progressive diseases interfere with airflow and make it hard for you to breathe. Some of the symptoms include:

  • Shortness of breath
  • Tight chest
  • Sore throat
  • Increased mucus production
  • Wheezing
  • Continuous coughing

There are preventative measures you can take to help relieve these symptoms. Plus, treatment can go a long way in alleviating the inflammation. Reducing the impact of COPD is easy to achieve and maintain with a few lifestyle changes.

Why You Need a Humidifier for COPD

Humidifiers have one job, and that’s to keep the air moist. They modify the quality of the air while controlling humidity levels. They’re best used in indoor environments that suffer from constant lack of moisture. They’re also important in areas that are constantly running an indoor heating system.

Some humidifiers have been designed to help ease COPD symptoms. One way they do this is by lowering humidity levels. Research shows that reaching optimal humidity levels is one of the best coping mechanisms for anyone suffering from COPD.

Key Considerations When Buying a Humidifier for COPD

Even though all humidifiers basically do the same thing, they’re not all equal. The best humidifiers for COPD have certain characteristics that make them stand out.

Here are a few tips on how to find the best humidifier for you.

Main Features

Look for these features to best manage your COPD at home or work.

Types of Humidifiers

Cool mist and warm mist are the 2 main types of humidifiers. Both types help regulate moisture levels indoors.

There are several differences between the two. For example, cool mist humidifiers are safer, yet they require more maintenance and regular cleaning.

However, warm mist humidifiers may pose dangerous hazards because of the hot steam being emitted. They also consume more electricity to heat up the water, which comes out as steam.

Size of Your Humidifier

You should choose a humidifier based on the size of the room where you’ll be using it. Manufacturers will give you an estimate of what room size their humidifier will work best in.

Typically, small humidifiers work great in rooms up to 300 square feet. Rooms that are 500 – 100 square feet will require larger humidifiers.

The best spot for your humidifier should be at least 2 feet above the ground. If it’s next to your bed, make sure it’s at least 3 feet away from the bed.

A smart tip is to place it on a towel, sheet, or a baking sheet. This helps protect your furniture and floors.


Some high-tech humidifiers have a timer function. One of the best advantages of having a timer is that you can turn it on or off whenever you want.

This would’ve been useful before I get home or get to my office. It would’ve ensured whichever room I’ve placed it in had reached its optimal humidity level before I got there.

Care and Maintenance

Cleaning your humidifier helps protect it from mineral deposits, which can result in bacterial or fungal growth. This should be done every 3 – 4 days to keep your humidifier in tip-top shape.

You should change the water in the humidifier every day. Humidifier filters should be changed every 2 – 4 weeks.

If you notice that the area around the humidifier is damp, this means there’s too much moisture in the air. The best thing to do is to turn it down. You can also reduce how frequently you use it.

Follow these cleaning guidelines to keep your humidifier clean and bacteria-free.

  1. Unplug the humidifier
  2. Empty the tanks
  3. Wipe the insides with a 3% hydrogen peroxide solution, chlorine, or other disinfectants
  4. Rinse with warm water
  5. Dry the insides

Benefits of Using a Humidifier

There are many models of humidifiers available today. Each is designed for a specific purpose, but they all share some common advantages.

  • Keep the air moist and at optimal humidity levels
  • Ensure good air quality
  • Prevent nose bleeds, dry skin, and chapped lips
  • Make it easier to cough up phlegm
  • Reduce airborne viruses, such as the cold and flu germs
  • Prevent static electricity build-up
  • Boost plant health
  • Minimize dust, bacteria, allergens, and other irritants
