Large Room Humidifiers Buyers Guide

Here are the factors to consider when in the market for the best room humidifier:


The following are the different types of humidifiers that can be used in a large room. They include:

  • Ultrasonic – This type of humidifier is best for use with children. This is because the mist it produces is cool and mild. It uses a nebulizer which vibrates, as it does so it emits water into the air.
  • Evaporative – Evaporative humidifiers use filters and a fan. The air is blown by the use of the fan over a wet filter. This produces a cool mist. This type of humidifier requires regular replacement of the filters. With such, it will require more costs.

Humidifiers can also produce warm mist or cold mist. For those that produce warm mist, the water is heated until it boils. The steam released from the boiling water is used to humidify the air. This type of humidifier is not advisable when you have children due to the dangers of scalds and burns. A humidifier that produces cold mist does not require any heating. Instead, the mist is released in the air as it is. This creates a pleasant cooling effect.

Water tank Capacity

The capacity of the water tank is an important aspect you would have to consider. Having a large water tank will save you from a lot of trouble. This includes having to refill the tank once the water is finished. Again, the larger your tank capacity is the more mist it produces. This also relates to the amount of space you would like to humidify. A large tank will allow you to humidify a bigger area than a small one.

Mist time

Mist time is the amount of time taken to be humidifier to be refilled. Before buying a humidifier check on the mist time. Note that, Portable humidifiers have a shorter mist time as they have a smaller water supply.

Coverage area

To ensure you get the right amount of humidity in the area, the room measurements must be correct. This will enable you to assess whether the amount of mist will be right for the intended space. The4 humidifier you choose to purchase should be able to cover the space you intend to humidify. To get the best amount of humidity, the humidifier should be able to do more than the space intended for it.

If you purchase a humidifier that is too small for your area the amount of mist will not be enough. While if you buy one that too large for your area you will have too much humidity. The good news is that there are humidifiers that can be fixed to your HVAC system. Once connected to the HVAC system the mist is taken and spread to your entire house. This is regardless of the size of your house. For people who wish to humidify the whole house, it is advisable to go for a whole-house humidifier.

Sound level

Talking of sound levels, noise is an irritant to most people. Especially if you intend to place the humidifier in a room you frequent. Getting to know the amount of sound your humidifier produces is important. Measured in decibels (db.), the higher the db. the higher the sound. While the lower the db. is the lower the sound produced.

The amount of sound produced by a humidifier is also determined by the speed, in that, at different speeds the amount of sound may either increase or decrease. With this knowledge ensure you know the number of sounds your humidifier will produce at different speeds. If you are one who loves silence, you should go for the Vornado Evap3. This humidifier is whisper silent at any one speed it works using.


Just like any other machine, humidifiers are prone to breaking down. For humidifiers, this especially true as the parts may come into contact with water at frequent times. You will find that your humidifier may still breakdown even after following the maintenance practices routinely.

Buy a humidifier that has the best terms of a warranty. Ensure you read and understand the warranty terms. A long warranty may be good but be keen to check its limitations. Most people do not take enough time to read through the warranty. This could go wrong in case your humidifier breaks down and you find the warranty does not apply.

Essential oils compatibility

To get nice authentic scents in the air would seem a very good idea. This could be easily achieved by adding some drops of the oil in the humidifier. If you are interested in such, the Levoit LV600HH would be best for you. This humidifier has a separate compartment for the oils. Instead of mixing the oil with the mist I, it discharges the oils all alone. Another idea if your humidifier lacks a different compartment is to add the oils directly to the water tank. But before you do it you should know that the oils could cause damage. The damage could be to the machinery; it could lead to blockage. The plastic, coating it. All this could interfere with the working mechanism of the humidifier.

Damage to the humidifier would mean additional costs. To prevent this, buy a humidifier that is compatible with the essential oils.

Extra Features

Diffusers are an important additional feature in a humidifier. Though expensive could help prevent a lot of issues health-wise. The best humidifiers are those that are also able to diffuse essential oils as well as the mist. If you would like to diffuse a large room, then go for the Everlasting Comfort Ultrasonic Cool Mist Humidifier. The advantage of this humidifier is that essential oils can be added to it. This is especially beneficial to those who suffer allergies, or headaches as the essential oils added could alleviate the symptoms.

An added feature would be having a clear display. This enables you to get to read the amount of humidity in the room at any one time. Thus, it will be easy to manage the humidity levels in a room.
