Here you have our list with best warm mist humidifiers for home use, all very affordable and easy to use electrically powered devices suitable for people who suffer from allergies and germs in the air.
If you are not familiar with such devices, then to know that a warm mist humidifier is a device designed to create a sustained mist of warm water vapor in a room. They are particularly useful during the cold part of the year when you have heating in the house and the resulting dry air. So if you are one of those that suffer from allergies, it is such a humidity that you need in the air.
The true reasons behind allergies are that those mucous membranes inside the head tend to become clogged with congestion as a reaction to allergens or germs. But when you have such a warm mist humidifier, this additional humidity helps in keeping the secretions thin so that you can easier expel them from the body.
Both warm and cool mist will work the same way, but in some cases, dependent on your symptoms, you might rather have one than another. This is why we have both options here in the list. A warm mist in the air will relieve your nasal stuffiness by penetrating the mucous membranes, while a cool mist can reduce swelling of the inflamed mucous membranes and relieve you from the pain.
There is even more to this, some scientific studies show that keeping humidity in the room at around 50% can reduce chances for viruses to survive long in the room.
Best Warm Mist Humidifiers for Home – my list
The devices in the list are ordered by the tank volume from smaller to larger. In most cases, this is more or less equivalent to their size and weight as well. Note that you have two main groups here:
- Humidifiers that produce only warm mist.
- Dual warm and cool mist humidifiers.
Obviously the second group includes devices that are more versatile in the sense that you can use them in any climate and throughout the year. So you can have warm mist in winter and cool mist in the warmer part of the year. They cost a bit more but this is a good investment in any case.
The warm mist humidifiers boil water and this is how the mist is created. This type almost always works as essential oil diffusers and aromatherapy diffusers. So here is our list, have a look.

This Honeywell HWM-705B HWM705B Filter Free Warm Moisture Humidifier and essential oils diffuser is in the group of medium size humidifiers with its 1-gallon (3.78 L) water tank.
One could describe it as a vaporizer because it has no fan, and this is not an ultrasonic device. So this is a simple device that makes the water warm and it evaporates in the area around. This is why they describe it as ultra-quiet. This also implies that it is without a cool mist feature.
This is also a filter-free humidifier so you have no additional expenses later on. It creates a soothing and visible warm mist that should counteract the effects of dry, harsh winter air. With such a water tank it is good enough for small to medium-size rooms. It can run up to 24 hours on one water tank, you have high and low settings so you can extend his time.
Honeywell HWM-705B HWM705B is also an essential oil diffuser, you have a tray for this purpose. There is an illuminated power switch and an easy to use manual knob control. As usual with such devices, it comes with an auto shut-off setting that switches it of when empty. You will notice a refill light that illuminates when the water tank needs to be filled.

Levoit Hybrid Ultrasonic Warm and Cool Mist Humidifier LV600HH
As the title suggests, this Levoit Hybrid Ultrasonic Warm and Cool Mist Humidifier LV600HH is designed for both warm and cool mist, and it works on ultrasonic technology. This is one of the larger devices of this type with its 6 L water tank.
As they claim, the benefit of having the warm mist function is that it helps kill germs, bacteria, and spores that may be present in the water, and at the same time the room humidification is more efficient and quick.
On the other hand, having the cool mist is great for warm climate like summer as it keeps sinuses and skin hydrated. It also alleviates congestion or a cough by keeping your throat and nasal passages hydrated. It is also known that the mist in general reduces static electricity on metal objections in your home.
This is a very easy to use device due to several reasons. You have a built-in sensor that will keep humidity at the level you define yourself. They describe it as set it and forget it type. It can run up to 36 hours continuously.
It comes also with an automatic shut off feature to protect you and the device, but as you probably know all the devices of this type have it. Yet another thing to point out is its remote control, so this is indeed convenient to have and to operate this device at night without leaving the comfort of your bed.
I have seen people asking so it is good to know that this device works also as an essential oil diffuser. You have an aroma box for this purpose, so do not add essential oils directly into the water tank or base, this may damage the device and they claim it can cause leaks.
But this is not all, this LV600HH is a filterless design, so there is no extra costs for this purpose. You might want to know also that it comes with a 1-year assurance, and they offer an option to extend it by another year when you register it online. They have a California-based Customer Support Team.
This device is designed to be placed on elevated-level surfaces such as desktops and tables, or nightstands. You have the following included: this hybrid ultrasonic humidifier, a remote control, a cleaning brush, 3 aroma pads, 3 absorption pads, and a user manual.
Who is it for
The mentioned ultrasound operation allows the device to work very quietly. So this is a device for people sensitive to sound, and for bedrooms.
But observe that you have a large 6 L water tank and a great output capacity up to 500 mL/h, so they claim that this device is strong enough to moisture rooms up to 753 square feet (70 m²).
This humidifier is very light with its 4.92 lb (2.23 kg) weight when empty, so moving it from place to place is easy. But this is a room device with its boxy structure so not something to carry on the trip.

So how to choose your warm mist humidifier for home
Here are a few tips that may help. Of course, you will first have to decide which one of the two main types to chose, warm mist only or both.
After that there is the issue of the capacity. You have the humidifiers in a wide range of water tanks volumes. So definitely go for a larger model if this is about a large room. On the other hand, if this is a small room, you can still go for a large humidifier simply because they always have several output options. By choosing a lower output, you will have several days run on a single water tank.
There are also differences in prices, this is related to features and functions. But quite generally, these are affordable devices. If you pay a bit more, you may have a few extra useful functions.
If you want to use essential oils, make sure to go for the models that allow for such a function, this is not so with all the models on the market.
If you are still undecided, here is my table with the best choices, this might help:
