What Is a Cool Mist Humidifier and Why Do I Need One? 

A cool mist humidifier creates added moisture to an indoor environment by expelling water vapor into the room. It is able to do this in two distinct ways: evaporative and ultrasonic.

Evaporative humidifiers blow a cool mist of water vapor into a room by having a fan positioned to move air through a moistened filter. This filter absorbs water from inside the humidifier from a tank that you fill.

Ultrasonic humidifiers use sound waves to turn liquid water into vapor. The end result is very similar to the evaporative humidifiers, but this model does not require a filter in order to improve humidifier levels.

Homes that benefit from having a cool mist humidifier are the ones that have lower than 30% humidity levels on a routine basis. Dry air can be just as damaging as air that is too moist because it will suck up moisture from any source it can. Since the human body is composed of 50-65% water on average, a low humidity home will dry out your skin quickly. Moisture in your hardwood flooring and furniture will also be absorbed by the air, adding to the damage potential.

The Advantages of Using a Cool Mist Humidifier

Every humidifier will help to stabilize humidity levels within an indoor environment when used on a regular basis. This will naturally make a home feel a little warmer than the ambient temperatures. Unlike other humidifiers, however, a cool mist humidifier doesn’t expel heated water vapor into the air, so actual room temperature changes are kept to a minimum.

Many cool mist humidifiers also require just a minimal amount of maintenance in order to function properly on a long-term basis. Evaporative models typically need the most work, with wick filter replacements and regular disinfection required for consistent results. Ultrasonic humidifiers may need cleaning from time to time, but that is it. Some models may have a UV light or a scale-reduction filter installed and these may need changing from time to time.

Portability is also an advantage of using a cool mist humidifier. Many models in this category have tanks that are 1 gallon in size or less, making them easy to carry from room to room. It also limits the physical requirements needed to maintain water levels for the machine, so even children can take care of a small cool mist humidifier that is kept in their room if you wish.

How to Find the Best Cool Mist Humidifier for Me

Each type of cool mist humidifier offers specific pros and cons that must be individually evaluated to determine what model and size is right for you. This is why these cool mist humidifier reviews are such a benefit to the shopping process. By evaluating the key features of each unit before purchasing one, you’ll be able to find the right humidifier at the best price today.

In general terms, however, you’ll find that all cool mist humidifiers are able to provide a home with these distinct advantages.

  • You will receive a large coverage area. A small cool mist humidifier can often stabilize humidity levels in any bedroom. Larger models are also available for whole home coverage when it is needed.
  • You receive utility benefits. Cool mist humidifiers are very energy efficient. It only costs a few cents per day to operate them under normal conditions in most homes.
  • You receive a higher level of safety. Even if you knock over a cool mist humidifier, the only real problem you may encounter is a big water puddle. There are no heating elements in place that could cause unintentional harm. 

Because these humidifiers do typically contain additional moving parts when compared to other humidifier options, many of them tend to be fairly loud when operating. If this is an issue for you, then consider an ultrasonic model to meet your needs. You’ll eliminate the sound of the fan and you can’t hear the sound waves that are used to produce the water vapor. 

What Are the Prices of the Best Cool Mist Humidifiers Today? 

You’ll find a number of cool mist humidifiers are competitively priced today at under $30. Most homes are going to be able to find a suitable one-room solution at this price range. Larger capacity models that cover more square footage can be found for under $100. Only a few models are priced above this level and offer a number of premium features that may not always be necessary to have for every home. This is where the cool mist humidifier reviews can be used to your advantage.

What Do Our Reviews Have to Say? 

Pure Enrichment

There’s a lot to love with this cool mist humidifier. The 360 degree nozzle gives you a lot of flexibility without getting the areas around the humidifier soaking wet. This model automatically shuts off when it runs out of water. The 1.5 liter tank offers you a reasonable amount of coverage that is suitable for most room sizes. We wish there was some more customization for the actual mist flow rates with this particular humidifier, but that’s really our only complaint. It gets the job done and sometimes that’s the best compliment you can give to a product today.

This humidifier gives you a pretty standard cool mist experience when you introduce it into a room. It gives you 18 hours of output from a 1.5 gallon tank. It has some adjustable mist volume controls and will automatically shut-off when it runs out of water. You can plug it in, turn it on, and basically forget about it and that’s a good thing. It’s also quiet enough that it won’t disrupt what you’re doing, so you can sleep, watch TV, or have a conversation with someone without difficulty. The price is nice as well, so it’s definitely worth taking a look at this particular humidifier.

This is the best cool mist humidifier for rooms that need to have constant humidity adjustments. It can produce up to 1.6 gallons of daily output for you, while the automatic humidistat monitors specific percentages on your behalf. If you reach your target levels, then it shuts off. It’s also portable enough that you can take it virtually anywhere you go so that you can always be comfortable. There is even an aromatherapy option that works remarkably well. All in all, we found this model to be quite consistent, fulfilling its value promise.

Tao Tronics

If you’re ready to upgrade your cool mist humidifier, then we would highly recommend this model to you today. The experience starts with the microporous cartridge that effectively filters out scale and microorganisms from your water supply. You can’t use oils or scents in the water without damaging the humidifier, but you can set and control mist and humidity levels in rooms over 500 square feet in size. The tank size is standard at 1 gallon, but you get up to 15 hours of running time on a single tank. It’s quiet, helps you feel better, and offers long-term potential for a relatively small investment.

If you want an ultra-large capacity humidification option, then this is the best cool mist humidifier for you. The 3 liter tank supports up to 33 hours of continuous use. The ultrasonic design keeps this model quiet and it produces no heat at all, so it’s safe for all households. A built-in sensor accurately tracks indoor humidity levels so you can maintain a comfort level that is suitable for you. It would be nice to have a 360 degree nozzle instead of a 90 degree turning radius, but that’s really our only complaint. This is a great design that will provide you effective results time and time again.
