Buyers Guide

If you are new to humidifiers or are simply not sure which one is the most suitable for your needs, here are some of the main features to take into consideration when buying one:

Your reason for buying a humidifier

When shopping for the finest humidifier, you should keep in mind why you are buying it. Is it for allergy or asthma relief? Do you need it for better sleeping or snoring? Is your skin itchy and dry? Do your beautiful wood floors and furniture dry up and crack? Are you looking for ways to reduce your heat bills? Do you have a newborn at home?

Depending on your reasons, you should choose a humidifier that is right for you.

The types of humidifiers

Ultrasonic cold or warm mist

This type turns the water into a mist that humidifies the air while keeping the floor and other surfaces dry. There are warm and cool mist humidifiers, and this one by Levoit is among the favorite ones that create and disperse soothing and humidifying cool mist throughout the room, in any direction of your choice.

It is suitable for use both in the dry summer and in the winter when the heating is on. This is one of the quietest humidifier types too.

Evaporative cool mist

These are more suitable for cooling the air during the hot and dry seasons. Evaporative cool mist humidifiers draw in the ambient air and then blow it back into the room through a wet wick in water. During the process, any heat is removed from the air, so the humidity produced is cooler.

Steam vaporizers

These humidifiers use a heating element to heat the water before being dispersed into the air. The main benefit of this type of humidifier is that the airborne bacteria and other harmful microorganisms are destroyed once they pass through the heated water.

Air washers

These are combined devices that purify the air and add humidity to it. They produce a cool mist. This type is usually larger, more durable, and is suitable for larger rooms and areas. They do require more maintenance than the other types.

The size of the humidifier

In order to get the maximum out of a humidifier, you need to make sure that it can humidify the room or the area you need it for.

Make sure you measure the area and choose one which has such capacity or a slightly larger one.

This humidifier by Levoit is suitable for rooms of up to 290 square feet.

The humidity level you want to achieve

Pick a humidifier that is powerful enough to achieve the desired humidity level in your room. You can regulate the humidity level by leaving a door open if it becomes too high.

It is not recommended to reach a humidity level of 50% and more because this creates the perfect conditions for dust mite and mold growth.

The Levoit Ultrasonic cool mist humidifier has 3 mist levels to choose from, so you can adjust the humidity level easily.

The noise level

You should check out the noise level of the humidifier to ensure that you won’t be bothered by it when it is on. This is especially important if you are planning on using it in your bedroom, in a nursery, or in your office.

The Levoit Classic 100 features a patented silencer and special filter, which minimizes the noise to less than 50 dB, making it suitable for even the lightest sleepers and for newborns.

The ease of use and maintenance

Humidifiers need to be cleaned periodically for hygiene purposes. Make sure you pick a device that is easy to clean and maintain.

Also, check if there are filters or descaling features that you will need to check, clean, and replace over time.

The Levoit Classic 100 is extremely easy to wash up and maintain and is also very simple to set and use.
