Buyer’s Guide

1. Cool mist vs warm mist humidifier?

Alright, so this is a very common question about the humidifier. People often confuse what kind of humidifier is best for them. Go through the below points to understand the difference between cool mist and warm mist humidifiers.

  • Best for children: Cool mist humidifiers are best for children as they throw out cool vapor. Whereas in the case of warm mist humidifiers, the vapor coming out from the device is hot. Therefore, which means you should not place a warm mist device near or inside the kid’s room.
  • Power consumption: Cool mist devices consume less electricity as compared to warm mist humidifiers. The only reason behind it is, cool mist units do not require a heating element to heat the water.
  •  Allergy and skin: Both cool mist and warm mist humidifiers are equally beneficial when it comes to cough and flu. Moisture in the air helps to prevent dry skin, chapped lips, nose bleeding, allergies and asthma.
  • Safe: Cool mist devices are safer to use as compared to warm ones. As they do not use warm water, the chances of hot water accidents become less.

2. How to clean a cool mist humidifier?

In order to prevent the growth of mold and mildews inside the tank, you should clean your humidifier properly. And in the case of cool mist models, you must clean them once or twice a week depending upon the usage. Now let us begin with the cleaning process of a humidifier.

You need:

  • White vinegar
  • Household bleach
  • Soft cleaning brush


  • Unplug the device and empty the water content inside the tank. Soak the tank in a large bowl containing lukewarm water. Keep it for 5-10 minutes.
  • Now remove the wicking filter. This filter is responsible for moisturizing dry air. Gently remove it as you do not want to tear it.
  • The next step is to remove the water tray present at the bottom. Soak the tray inside white vinegar for about 15-20 minutes. If your certain part of the tray is not cleaned properly due to its shape, make use of a sponge pad.
  • After soaking the water tray in the vinegar clean it under warm running water. Doing this will prevent the smell of vinegar from mixing into the humidifier.
  • Add 1 tablespoon of bleach in 1-gallon water and fill the water tank with it. Now close the tank opening and shake the tank vigorously so that bleached water reaches every corner. Empty the bleach water in the sink. Now fill the water tank again, but this time only with plain water. Shake it again and pour the water until the smell of bleach goes away.
  • Similarly, perform the same procedure with the water tray. The reason to use bleach in the cleaning process is, it acts as a disinfectant as well as removes mineral residue.
  • Lastly, dry out all parts properly before putting them back together.

3. Can you put essential oils in a cool mist humidifier?

Generally, you should not diffuse essential oils in a cool-mist humidifier. They are meant to moisturize the air and keep humidity level intact. But there are some models that contain a slot to add essential oils.

Many people add essential oils in a cool-mist humidifier thinking it might work as an oil diffuser. But they forget one major thing, they cannot control the output of oil. And an excessive amount of essential oil present in the air can be dangerous. So in our opinion, do not mix essential oils inside the humidifier. Still, if you wish to have a humidifier in which you can add essential oils then go for Everlasting Comfort Ultrasonic Humidifier.
