Can Humidifiers help with Allergies?



Humidifiers are devices that can be used to maintain the humidity in the atmosphere of a room. Their mechanism is quite simple and easy to understand. Basically, all types of humidifiers have a water tank which has to be filled with clean water to be used by the device to spread moisture across the atmosphere. The process of dispersing the water varies depending on the type of the humidifier, warm mist or cool mist humidifiers. But is a humidifier good for allergies?

People who suffer from allergies have to take a lot of precautions to avoid any health hazards. One of the most important one is to merely avoid their allergens which can travel very easily in atmosphere with lower levels of moisture. Also dry air can dry up your nasal passage leading the body to produce more mucus which can prove out to be very harmful for your health in case you are suffering from asthma along with allergies. So coming back to the question, do humidifiers help with allergies? The answer is most certainly “Yes” as Humidifiers help in maintaining the humidity levels of the air in the room preventing dry air to spread the harmful allergens and soothe dry sinus passages so that it could continue flushing out allergens like dirt, bacteria and other micro-organisms by its normal mechanism. Also, with the correct moisture levels in the atmosphere, you can avoid health issues like runny nose, cough and sore throat.

When we talk about humidifiers for allergies, there are certain things that you should consider before buying and beginning to use one:

  1. Maintain the appropriate humidity levels: The most appropriate humidity levels should range from 30 to 50 percent with the ideal level at 45 percent. Just like dry air, atmosphere with high levels of moisture can also affect your health terribly, so always make sure to keep a check of your room’s humidity levels using a Hygrometer. Consider buying a separate Hygrometer or a Humidifier with the feature to measure the humidity levels to avoid any health issues.
  2. Use distilled water: To prevent the allergens and harmful micro-organisms in dirty tap water from spreading into the air through Humidifiers, you should make sure to use very clean or distilled water to fill up the humidifier tank.
  3. Type of Humidifier: There are various type of humidifiers available in the market like Ultrasonic humidifiers, Impeller humidifiers, Central humidifiers and Vaporizer humidifiers which can be basically categorized into Warm mist and Cool mist humidifiers. So, before buying a humidifier, ensure that you have considered the pros and cons of each of the types available.
  4. Keeping it clean: Stagnant water in the humidifier tank may get spoiled by the growth of micro-organisms with time. So to prevent those bacteria and fungi from spreading into the air by the next time you switch on the humidifier, you should make sure to completely empty the water tank and clean it up properly as frequently as possible.
