What Does a Humidifier Do? 

A humidifier is, quite simply, a device that increases humidity — the amount of moisture in the air. This is generally accomplished through the production of steam or cool mist. 

Three of the most common types of humidifiers are cool mist humidifiers, warm mist humidifiers, and ultrasonic humidifiers. All three run on a tank of water also known as a reservoir and utilize different technologies to turn that water into vapor. 

Cool mist humidifiers filter water from the reservoir to remove minerals and impurities before the water is evaporated into the air. These models can be a little noisy and may require frequent maintenance to keep the filter clean. Warm mist humidifiers are generally quieter but can be difficult to clean. Some require the use of heat to produce steam which may not be the safest option for use around babies or children. 

Ultrasonic humidifiers are incredibly popular. They utilize a vibrating diaphragm to release water droplets into the air. They’re virtually silent and they don’t use any heat. Ultrasonic humidifiers are generally easy to maintain and simple to operate.

How Do Humidifiers Help with Allergies? 

Allergy symptoms can result from exposure to any number of things. Many people suffer from allergies to dust, pollen, or pet dander but allergies can also be triggered by certain fabrics, household chemicals, or cleaning supplies. A humidifier may not be as effective as an air purifier against smoke, dust, and other airborne allergens, but it might help. 

The primary benefit of a humidifier for allergies relates to increased moisture in the air. Low humidity can aggravate respiratory symptoms like those associated with allergies and may reduce your susceptibility to colds and other respiratory illnesses. 

Keep in mind that while adequate humidity might be beneficial for allergy sufferers, humidity that is too high could be problematic. When the humidity in your home is too high, pet dander and dust may stick to surfaces and can then be picked up by your clothing and skin. Too much moisture in the air could also contribute to the growth of mold and mildew.

Other Tips for Reducing Allergy Symptoms

Everyone is affected by allergies differently, so the best place to start is with your doctor. Your doctor can help you determine the cause of your allergies and help you determine how best to mitigate symptoms. In many cases, you’ll need to take steps to avoid the allergen as well. 

Here are some tips for reducing allergy symptoms:

  • Avoid going outside on windy days – the best time is after a rain because the rain helps clear pollen from the air.
  • Make sure to use high-efficiency filters in your home’s heating and cooling systems.
  • After mowing the lawn or doing yardwork, remove the clothing you wore and take a shower to remove allergens from your hair and skin.
  • Use air conditioning in the car instead of opening the windows.
  • If you’re very sensitive to outdoor allergens, wear a mask when you’re outside and keep your hair and skin covered. 
  • Wash bedding regularly and use a vacuum to clean upholstered furniture. 
  • Keep your home organized and free from clutter that might accumulate dust.
