Cool-mist vs Warm-mist Humidifier – Difference and Comparison

A humidifier is used to alleviate discomfort caused by dry skin, allergies, asthma and airless sinuses by increasing the moisture capacity ( humidity ) in the air. A ardent obscure humidifier heats water to produce steam that humidifies the air. A cool mist humidifier releases bantam water droplets into the air out .

Purpose

Both cool-mist and warm-mist humidifiers offer relief for allergies and asthma. If a person can breathe well in a sauna then a strong mist humidifier is desirable. If a person finds it difficult to breathe in a sauna then a coldness obscure humidifier is suitable.

Types of Humidifiers

Types of Cool Mist Humidifiers

  • Impeller humidifier – A rotating disc throws water on a diffuser which breaks water into fine droplets. The droplets exit as a cool fog mist.
  • Ultrasonic humidifier – An ultrasonic diaphragm vibrating at very high frequency breaks down water into fine droplets which exit as a cool fog. This type of humidifier is silent.
  • Wick/Evaporative humidifer – A wick is a filter that absorbs water from a reservoir. The wick provides larger surface area for the water to evaporate. A fan blows air to aid evaporation.

Types of Warm Mist Humidifiers

  • Steam humidifier – It boils water and releases steam into the room. A medicated inhalant can be vaporized along with the water.

Humidity levels

Humidifiers are required to maintain the moisture content of a room. 35 to 50 % humidity horizontal surface is considered to be goodly. A broken humidity level results in dry and itchy peel or chapped lips. Humidity grade greater than 50 % results in growth of mold spores, bacteria and debris mites. 40 % humidity is required for melodious instruments to prevent their craze or crack of finish .

Optmimum humidity level for the flu virus

The influenza virus thrives well when humidity is either over 98 % or between zero and 50 %. So Dr. Linsey Marr, a research worker at Virginia Tech, recommends keeping humidity levels around 50 % ( but not over 60 %, because that can cause mold buildup ) to give the influenza virus the least chance of survival.

Pros and Cons

Advantages of Cool Mist Humidifiers

  • The absence of hot water or heating element eliminates the risk of injury and is safer to use with children around.
  • The tank is easier to clean.
  • The wick type humidifier is self-regulating as the evaporation from the wick is relative to the humidity level of the room.

Disadvantages of Cool Mist Humidifiers

  • A fan is required to dispel the mist into the room and hence can be noisy.
  • Any minerals, dust or microorganisms might be diffused along with the mist. The minerals diffused (mostly calcium) might settle on furniture and nearby objects and are difficult to remove. The dust and microorganisms can worsen the allergy or asthma. Hence it is advisable to use purified or distilled water.

Advantages of Warm Mist Humidifiers

  • The minerals and dust in the water are not diffused along with the steam.
  • Any medicated inhalant (such as Vicks) can be added to the water to be diffused into the room.

Disadvantages of Warm Mist Humidifiers

  • The presence of heating element and boiling water pose a risk of scalding and could be dangerous with children around. There is also a risk of fire.
  • Mineral deposits from hard water make cleaning harder.
  • Bacteria thrive in the presence of warm water and hence require frequent cleaning.
  • Heating element requires more energy to operate. This increases power consumption and operational cost.

Maintenance

All humidifiers require sustenance. here are some steps you can take to keep a humidifier in good shape :

  • Do not let water sit idle in the reservoir as this might lead to bacterial infection and mold formation. Clean the tank and filter regularly.
  • Rinse the tank after cleaning to avoid harmful chemicals being released.
  • Keep the area around the humidifier dry.
  • Use distilled or demineralized water.

Price

Products on the tilt of best selling humidifiers on Amazon normally range from $ 30 to $ 80, with some high-end humidifiers priced at deoxyadenosine monophosphate much as $ 170 .
