Important considerations


  • Improve Air Quality: Humidifiers add moisture to the air, helping to reduce the amount of dry, dust-filled air in the home. This can help reduce allergens in the air and improve overall air quality.
  • Reduce Irritation: Adding moisture to the air can help reduce irritation of the throat and nasal passages, making breathing easier.
  • Reduce Static Electricity: Dry air can cause more static electricity to build up in the home, leading to shocks. Adding moisture to the air can help reduce static electricity.
  • Reduce Sinus Pressure: Dry air can lead to increased sinus pressure and congestion. Humidifiers can help reduce this pressure, making breathing easier.
  • Reduce Snoring: The moisture from a humidifier can help reduce snoring by making breathing easier and reducing nasal congestion.
  • Reduce Allergy Symptoms: Humidifiers can help reduce allergies by reducing the amount of allergens in the air. This can help reduce symptoms such as sneezing, itching, and watery eyes.


  • Noise Level - Humidifiers can be noisy, especially those with fans. Some models are quieter than others, so you may need to find one that matches your desired noise level.
  • Maintenance - Humidifiers need to be cleaned and refilled regularly to ensure proper function and to prevent mold and bacteria growth.
  • Cost - Humidifiers can be pricey, with some models costing hundreds of dollars, so you should consider if the cost is worth it for your desired level of usage.
  • Space Considerations - Depending on the model, some humidifiers can be quite large, so it is important to check to make sure it will fit the space you have available.
  • Humidity Levels - If the humidity levels in your home are too high, it can lead to an increase in mold, dust mites, and other allergens, so you should monitor your humidity levels closely.

Best alternatives

  1. Dehumidifier - Removes extra moisture from the air, making it a great alternative to a humidifier if the air is too moist.
  2. Air Filter - Removes particles such as dust, pollen, smoke, and pet dander from the air, without adding moisture.
  3. Ventilation System - A system of fans and ducts that can be used to bring fresh air into a space and push stale air out.
  4. Air Conditioner - Cools the air, while also removing moisture from the air, making it a great alternative to a humidifier in hot, humid climates.
  5. Heater - Warms the air, without adding moisture, making it a great alternative to a humidifier in cold, dry climates.

An interesting fact about humidifiers is that they were originally invented in the 1940s by a doctor to help his asthma patients breathe easier. It was found that a moist environment could reduce the dryness in the air that was causing breathing difficulties. Since then, humidifiers have become a staple household item, used to reduce cold and flu symptoms and even prevent static electricity shocks. According to the Allergy & Asthma Foundation of America, humidifiers can help to reduce symptoms in those with allergies, asthma and other respiratory issues. Source
