When winter strikes, bedrooms with stale, dry air can immensely affect sleep quality and duration, as well. There are some other drawbacks, such as a higher risk of allergies, dry skin, and chronic congestion.
In the U.S, the air quality is susceptible to extremely high or low temperatures that dry out the air. It all depends on the climate that affects negatively on our health. In this case, the best humidifier uses the cold or warm mist to refresh indoor air is beneficial.
Because the humidifier is perfect for good sleeping experience when you suffer uncomfortable conditions related to air quality, however, there is a wide range of humidifiers that are available on the market. To select the best one for your bedroom or office is always a challenging step.
For this reason, we conclude our article with a buying guide so you’ll know about the essential considerations such as humidifier types, features, cleaning, and care instruction. These key factors are notable when you are buying a humidifier.
Just as we have reviewed many types of a humidifier in our list of the best humidifiers but there are two major types. These include:
When it comes to warm mist humidifiers, they use to heat water. There is a built-in element until it reaches its boiling point, and then release warm steam or steam vapor into the surrounding area. When water is heated, this type of humidifier kills harmful bacteria and mold before emitting the steam, which results in a reduce allergy potential.
Also, there are some types of warm-mist humidifiers, including steam humidifiers and vaporizers. These types emit steam and then vapor the steam.
Well, the cool-mist humidifiers are categories as evaporative humidifiers, ultrasonic humidifiers, and impeller humidifiers.
The evaporative humidifiers included with a fan to blow air over a wet wick filter while this design is a relatively clean bit also one of the loudest options.
When it comes to Ultrasonic humidifiers, it produces cool mist using a vibrating nebulizer, making them pretty quiet but also resulting in tiny water droplets that accumulate throughout the room.
The third type as the impeller humidifier; it produces mist using a rotating disc. This type of humidifiers is the quietest humidifier and most expensive, as well.
The second aspect is a performance that is noticeable when buying a humidifier. Firstly, you should consider the size of your bedroom. Because the humidifiers have different sizes or shape so you can quickly identify which is the best one to place in your bedroom. However, if you have a large room, then a powerful humidifier is needed. Bur powerful humidifiers can be overwhelming and excessively loud.
On the flip side, if you are going to get a humidifier for a great place, then it requires a high-output setting which makes it noisy that is not suitable during sleep.
The water capacity of a humidifier may fall between 300ml to 4 gallons. If you are going to get a humidifier from mid to large size room, then select has that has a 1-gallon water reservoir.
It is also good to know that the water capacity is linked to the humidifier’s runtime. If you want a larger tank, it will release longer steam or mist before the unit automatically shuts off.
Size and Weight
The best humidifier is one that comes with a compact design but enough performance. Because this unit is to be placed mostly in the bedrooms. That’s why it is designed to be small, so you will quickly put it in the bedrooms or office.
It is recommended to measure the area before getting a humidifier to ensure the reservoir can be filled.
Additionally, it is also good to check its weight, since they will ostensibly be carrying the unit to the sink daily to refill the tank.
Each humidifier specifies a particular coverage area. The warm-mist humidifiers have smaller coverage places than the cool-mist humidifiers offer. While the smallest humidifiers are extended for desktop use, and the larger one can add moisture to an entire room.
When it comes to the humidifiers for small rooms, fall somewhere in the middle. It can lead to mold and other air-quality, so finding a model with the optimal coverage is kind to pick.
Each humidifier product noise, but the ultrasonic models tend to be quiet while evaporative and warm-mist humidifiers are usually the loudest. That means, the sound is not necessarily disruptive and may serve as white noise that helps when you sleep.
Although some of the larger humidifiers are the loudest ones than smaller models, they provide high-speed settings.
For the cleaning, it varies by model. Some humidifier models require daily maintenance, while others only need to be cleaned and cared for once in a week. You should check the manufacturer’s instruction manual to learn more details.
Price and energy Use
The best humidifiers are generally inexpensive. Either the most warm-mist or cool-mist models available for $100 or less, though some cost as much as $200. The bigger models cost more than smaller ones. If a humidifier has advanced features and settings, it may probably have a higher price-tag that an essential humidifier has.
However, ultrasonic humidifier are energy efficient than others.
How to clean a humidifier?
A humidifier needs frequent cleaning, so it is functioning correctly. It can improve bedroom air quality; dirty humidifiers often hurt health. So, we have some general guidelines to follow to ensure the humidifier is clean in a proper way.
First of all, empty the water tank every day. It doesn’t matter either in the morning after waking up or in the evening before going to bed.
It’ll need to rinse out and scrub the reservoir at least two to three times a week. If the water appears murky or discolored, then you should rinse the water tank.
Separate the humidifier and clean each component every one to two weeks. It also depends on owner manual recommendations. Besides, you can wash with hot, distilled water, also sterilize the parts with hydrogen peroxide.
