5 Best Cool Mist Humidifiers

What You Need to Consider Before Buying Cool Mist Humidifiers

Choosing a cool mist humidifier may seem like an easy task.

However, the fact is, there are several things that you need to consider.

1. Noise Level

One of the first thing that you need to consider is the noise level of the humidifier. This is important since humidifiers are usually turned on when you sleep or when you want to rest.​

Because of this, you would not want one that sounds like an old humming aircon, you might not be able to rest under the annoying noise of the humidifier.

Product packages and labels usually come with the noise level rating. So with this, it is suggested that you take a look at these ratings before buying them. Noise levels come in numerical ratings. They usually appear at the back or bottom portion of the unit​

2. Auto Shut Off Feature

There are several cool mist humidifiers that come with an auto shut off feature. This feature is also important since it saves time for you to constantly check on the unit and turn it off manually.

With this function, you can doze off in peace while leaving the unit to turn off at a certain time.

Leaving too much humidity in a room is not good since it retains moisture in the room, resulting to accumulated moisture in appliances leading to eventual damage to them. Moreover, having this feature also saves you a lot of money for your electric bills.

​With the auto shut off feature, you are able to set the level of humidity emitted as well as the desired time for emission.​

3.​ Antibacterial Feature

Not all cool mist humidifiers have the capacity to remove bacteria and microorganisms in the unit. Some units employ the use of antibacterial agents such as phenol and hypochlorite embedded in the system to help remove or prevent the accumulation of harmful pathogenic microorganisms.

More advanced humidifiers come with special filters or cartridges with antibacterial agents while recent innovations employ the use of UV light to do this function. You will know if the humidifier comes with this feature because manufacturers usually place them in the packaging or labels.​

4.​ Area Coverage

​A good cool mist humidifier must also have ample area coverage. Humidifiers have a wide array of coverage ranging from a small room to even a large function room.

Before considering a humidifier, you must first know its area coverage as you would not want to have one that can power an entire large function hall when all you have is a small bedroom. Because of this, there will be excess moisture and humidity in your area.​

If you want a safer option you can always opt for a cool mist humidifier with a large coverage area and then place it in the center area or the living room. This way, you will be able to humidify several rooms with one unit.

5. Tank Capacity

One of the important things to consider is a humidifier with a large tank capacity. A humidifier with a large tank capacity will elicit few frequencies of water refilling. That way, you don’t need to constantly check on the unit whether it has adequate water supply.

Moreover a large tank capacity will also be able to humidify a room for more time compared to those with smaller capacities.

​​6. Maintenance

​Lastly, you also need to consider a humidifier with lesser maintenance needed. This is important as you would not want to constantly clean the unit over and over again.Humidifiers

can accumulate an amount of mold and mildew, because of this clean up and maintenance is a must. With the advent of advanced technology, newer humidifiers have employed the use of self cleaning options with a single touch of a button.

With this, you save time in cleaning the unit.​
