How To Choose The Right Humidifier In 2021- Best Humidifier Buying Guide

A humidifier is a device that releases mist in the room to regulate humidity which keeps your family breathing easy and prevents hands, feet, throat and nose from getting dry in the winter. Humidifiers are considered good for asthma patients. They are highly recommended for people with sinus and breathing problems. If this rings the right bells then read below what steps you should take to get the right humidifier for your family. 

Types of Humidifiers 

There are two basic types of humidifiers- warm mist and cool mist. You can choose the one according to your needs. For example the humidifiers with warm mist are not suitable for children rooms etc. 

Humidifiers with filters and filterless. The humidifiers with filters clean the water with it while the filterless humidifiers have a built-in purifying system they are called ultrasonic. The filterless humidifiers come a little pricey. But if you would compare it with humidifiers with filters that require filter changing frequently, so filterless is the best option. 

The filterless humidifiers use an ultrasonic system which vibrates to clean the liquids inside. They are also quieter ones. 

Why to choose a good humidifier for baby rooms?

Our babies are very sensitive to certain environments and their system reacts differently to each change of weather. When they wake up in the morning with a stuffy nose or scratchy throat you would realize you need to keep the humidity in the room moderate. Since there are not many options left when the baby gets cold or gets infected with a virus. It’s better to have a humidifier specially for children’s rooms. 

The mist that a humidifier releases soothes your baby’s respiratory system and comforts his throat. 

How To Choose A Humidifier?

There are few things that you must consider before buying a humidifier. We have discussed those in detail below. 

Size And Power: Make sure the size of the tank and power of the humidifier is appropriate for the size of your space. If it’s too large for the room the condensation can begin to form which can result in bacteria and mold buildup.

If it’s too small it would not produce enough vapor to keep the right humidity in the room. You need to check the sq. ft of your room and the coverage the humidifier offers which you are going to buy. 

Customization: You should also check the customization feature which might not be as effective as they should be in the most humidifiers. 

Type: Consider which type of humidifier you need– warm or cool mist one; with filter or filterless. We have already mentioned the difference above. 

Display: You should go for the humidifiers with LED display which is easy to monitor at night. 

Running Time: You should also consider the running time of a humidifier. As each humidifier gives different running time. 

Auto Mode: You should also consider whether or not a humidifier shuts off automatically or regulates humidity level automatically. It’s a small thing but can impact the overall performance of the humidifier. Those humidifiers which do not shut off when the water runs out they overheat and malfunction during the next run. 

Safety And Regulation: It’s necessary to keep in mind the safety of your family. If someone from your household specially a baby wakes up with a stuffy nose or dry skin you should regulate the level. That feature also needs to be checked while buying a humidifier. It’s hard to find, but you need to figure it out. 

Oil Diffuser: You should also check if the humidifier you are buying also diffuse essential oils or not. As some may not. Each humidifier is different from the other one depending on the brand and model you are buying. 

Custom Night Lights: This is not a necessary thing but since the options available you can choose a humidifier with a color changing night light. These lights are very soothing and comforting. 

We have mentioned some of the high quality humidifiers that you can choose from which have received positive reviews.
