Best Humidifier for Asthma and Allergies

Scientists usually point at dry air as the primary cause of dry skin and irritated sinus passages. In this regard, doctors recommend the use of humidifiers to alleviate these conditions. This is especially important if you are already battling asthma or indoor allergies. In response to these challenges, we have identified the 5 best humidifier for asthma and allergies.

Another point to note is that you have to be mindful about how much moisture is being introduced into the air. This is because too much moisture can become a breeding ground for dust mites and the growth of molds which can significantly affect people with asthma or allergies. 

You should therefore consider a humidifier that has a humidity monitoring feature. This will allow it to detect when it has provided enough moisture to the air. It should thereafter switch off the device when it has provided enough moisture to the air. This prevents the introduction of excess moisture to the air.

Summary of the (5) best humidifier for asthma and allergies

Do humidifiers help with asthma?

Yes, humidifiers do help with asthma. Low humid conditions considerably affect individuals with asthma. When the air is dry, the nose membrane and throat become dehydrated. This leads to the inflammation of the airways. Thus, triggering asthma symptoms that could become hard to manage. However, a humidifier releases moisture into the air, making the sinuses and throat hydrated. This eases and improves the breathing of the affected person. 

What are the Humidifier benefits for asthma and allergies?  

Humidifiers add moisture to the dry air. This helps prevent common colds and flu. According to the CDC, colds and flu can trigger asthma. Flu can worsen the swelling of the nasal passage and increase mucus production. This leads to the tightening of the air passages causing asthma attacks and breathing may become a problem. 

Similarly, breathing in moist air can relieve the symptoms of allergies. Take an example of allergic rhinitis. This is characterized by inflammation of nasal tissues, nasal congestion, and irritations. A humidifier will help you moisten the sinuses and reduce tissue inflammation. This provides relief from allergy symptoms. 

Is a cool mist or warm mist humidifier better for asthma?

Cool mist and warm mist humidifiers equally help improve asthma and allergy symptoms. Your choice among these two is a matter of comfort and affordability. Warm mist humidifiers release visible steam vapors into the air. They reduce mineral dust accumulation, bacterial aeration and are less expensive. However, warm-mist humidifiers are not energy efficient. Furthermore, they require frequent cleaning. 

For the cool mist, they are usually easy to clean and are less noisy. If you happen to be using hard water, cool mist humidifiers that do not have filters usually release white dust and microorganisms into the air. Any humidifier you choose should have qualities that can help you improve your allergy and asthma symptoms. 

What is a good humidity level for asthma?

According to National Asthma Council Australia, the ideal indoor relative humidity should be between 30 to 50%. They state that humidity levels below 30% lead to very dry air. When the air is dry, it increases the chances of catching the flu, which can trigger asthma. This is because airborne viruses tend to survive longer in dry cool environments. On the other hand, higher humidity creates a favorable environment for dust mites and mold growth. These two can trigger asthma and allergy attacks. Therefore, when using a humidifier, ensure the relative humidity is within 30-50%. 

Can humidity worsen asthma?  

As discussed above, when humidity falls out of the required range, it triggers asthma. When the relative humidity is less than 30%, chances are high to catch the flu. Flu aggravates the swelling of the sensitive airways and intensifies the production of mucus. A combination of the two leads to the narrowing of the air passages. This may worsen asthma as breathing becomes more difficult. 

How to choose a humidifier for asthma and allergies?

• Humidistat. When choosing a humidifier for asthma and allergies, you should ensure the humidifier has a humidistat. This helps you to continuously monitor and regulate the indoor humidity to ensure it stays within 30-50%. When the relative humidity keeps within that range, you are less likely to experience any asthma or allergy attacks.

• Easy cleaning. Humidifiers can make asthma worsen and trigger allergies, if not cleaned properly. This is because dirty humidifiers harbor bacteria and fungi. These are then released into the air. When in the air, fungi induce allergic respiratory reactions. Similarly, fungal antigens can trigger or worsen asthma.

• Anti-bacteria features. When choosing a cool-mist humidifier ensure it has anti-bacterial features such as ultraviolet lights (UV light). This helps reduce germ growth in the water tank. Ultimately, this will reduce the chances of bacteria being introduced into the air. 

• Area coverage. The humidifier you choose should match the size of your room in terms of coverage. This helps you maintain a balanced relative humidity throughout the room. Measure the square feet of the room you intend to place your humidifier and use this as your basis. The different brand manufacturers usually add a label of the area coverage of the unit on its packaging or product description.
