This guide will walk you through everything that there is to know about humidifiers, from their types and purposes to their advantages and disadvantages. Humidifiers may sound unimportant but can be worth every penny to those who appreciate and use them.

So what is the point of a humidifier?

Room air humidifiers have one main goal, and that is to help improve the breathable air quality in that select space. It emits water vapors in the air to increase the level of humidity to combat dry weather and can also help alleviate certain issues that people have, such as sinus headaches, sneezing, and coughing.

Humidifiers are often used in times of cold, dry weather and dry heat, but they can also be used year-round to help people who are sensitive to dry weather. They are exceptionally beneficial for rooms and places with low air ventilation as well, such as areas without windows, or an attic or basement.

To know what type of humidifier is right for you, read below in order to gain a better understanding of the various types available in the market today.

Humidifiers have become much more modernized as time has gone on and now there are many new varieties designed to suit your various needs.

In order to choose the right type of for yourself, you need to understand what each type of humidifier is designed to do to maximize the benefits that you are trying to receive. Careful consideration needs to be put into a variety of factors, such as the size of your room, the weather and climate that you live in, and the noise level of the humidifier.

It is also important to take into account the type of building you live in as well as how much ventilation is available in the room that you are interested in getting a humidifier for.

For larger rooms with less ventilation, you might want to consider a larger humidifier with more power and capability in order to cleanse the entire room of dry air and alleviate any related problems completely.

Things to Consider When Buying a Humidifier

Be cognizant of your budget, your requirements, and your reasons for getting a humidifier. Below I’ve broken down the main things to consider and take into account when looking for the right humidifier.

1. Noise

Noise is a big issue for some people and is something to take closely into account when purchasing a humidifier. If having a quiet air purifier is your goal, then make sure you invest a little more in a humidifier that is specifically designed for reduced noise levels. This can be helpful if you plan on leaving the humidifier on at night while you sleep.

2. Special Features

Some of the features that one should look for when buying a humidifier is a timer and auto-shut off functionality as it allows you to use it while you sleep without having to turn it off manually. Some advance humidifiers have a humidistat to monitor humidity level in your room and prevent from over moistening the air.

3. The Room Space and Size

How much space is available in the room is also a key aspect to take into consideration when deciding what kind of humidifier you wish to purchase. Some machines are much larger and more clunky than others, while some humidifiers blend right in with furniture and do not take up much space. Before you purchase a humidifier, figure out how it will fit into the room you plan on using it in.

4. Room Ventilation

In bigger rooms with less ventilation, a bigger more powerful humidifier is required to handle the extra work. Locked up rooms with low ventilation can get stuffy over time, so if there is limited access to a window or fresh air that you might want to invest in a more powerful humidifier. Conversely, leaving the window always open in hot, dry climates requires your humidifier to work overtime as well. You need to find a balance between the design and layout of the room.

Types of Humidifiers
