Best Humidifier and Diffuser Combo

Last updated on May 30th, 2018 at 08:33 pm

In this article we explore the best humidifier and diffuser combos on the market today. We start by laying out the important qualities to look for when shopping for one of these items. Later on we take these qualities and use them to screen the available combos to provide our recommendation for the top humidifier/diffuser as well as a runner up.

The Screening Process

In this section we talk about the criteria we used to decide which appliances we would review. One of the first things that stands out during research on humidifiers can be found in the user manual. Most humidifier manufacturers indicate their humidifiers are not to be used with essential oils.

However, there are a few newer manufacturers making high capacity humidifiers that are compatible with essential oils. In this article we define high capacity as larger than one gallon. Until recently, people looking for one appliance that would both add humidity to the air and diffuse essential oils. We review two of these humidifiers later on in this article.

Generally, humidifiers can add a lot more moisture to the air than the best essential oil diffuser. The downside to this is that they are bulkier, which limits where they can be set up in a room. This article focuses on humidifier and diffuser combos that are sized to treat one room. The humidifiers in this category are comparable in size to the larger essential oil diffusers we discuss on this page.

There is a special class of essential oil diffusers that add moisture to the air just like a humidifier. They are called a variety of names: cool mist diffuser, ultrasonic diffuser and so on. In this article we will refer to them as ultrasonic diffusers. They get this name because they produce ultrasonic vibrations to agitate the water and cause it to form a mist.

Capacity

After examining this set of appliances we further narrowed our scope by looking for ultrasonic diffusers with larger capacities. Many ultrasonic diffusers have very small capacities, under 500 mL (slightly more than 2 cups). At the same time, we limited the size of the humidifiers we would consider to make sure the overall size of the appliances we reviewed were similar.

The capacity is important because it is directly related to continuous run time. Humidifying the air is a long term process. It also works best if there is a near constant supply of moisture going into the air. The same principle applies to aromatherapy. On to the recommendations!

1500ml Aroma Essential Oil Diffuser by Exqline

The first diffuser and humidifier combo we recommend is the 1500ml Aroma Essential Oil Diffuser by Exqline. It has a high capacity of just over 40 ounces of water, the highest capacity we found in a humidifier and diffuser combo. This gives it a run time of up to 20 hours. Read on to see some of the more unique features that set this ultrasonic humidifier apart from the crowd.

The Exqline Diffuser is one of the few humidifier combos that has a continuously variable output. This means that it isn’t just a high or low setting for how much moisture it puts into the air. You can turn the knob to adjust how much mist your diffuser puts out.

Area of coverage

This ultrasonic diffuser can provide restorative humidity for up to a 325 square foot area. It also provides aromatherapy for up to 450 square feet. Because of the large area it can provide humidity for, we are confident in recommending it as the best humidifier and diffuser combo on the market today.

There is one downside however, it does not come with any pre-set timers. This means that the ultrasonic diffuser will run continuously until you turn it off. It does have a safety feature to turn itself off when it runs out of water. The auto-shutoff feature is commonly found on quality humidifiers.

URPOWER 1000 ml Essential Oil Diffuser

The next product we considered for best humidifier and diffuser combo is the URPOWER 1000ml Essential Oil Diffuser. This diffuser comes from a well-known brand and has a few features that are not available on the Exqline.

These features include an LED that can change between 7 different colors. It also has a remote and preset timers. These give you some convenient options. You can also just let it run and rely on the automatic shut off the same way you can with the Exqline.

The 1000 ml tank allows it to run continuously for up to 20 hours. This essential oil diffuser can provide humidification for up to 269 square feet. The aromatherapy benefits from the essential oil diffuser extend to a full 430 square feet. Both of these areas are slightly smaller than the area treatable by the Exqline.

SimpleTaste 4L(1.06 Gallon) Ultrasonic Cool Mist Humidifier Aroma Essential Oil Diffuser

This is one of the newer humidifiers on the market today that is compatible with essential oils. It operates at an incredible volume of only 35 decibels, about as quiet as a library. The humidifier produces a constant sound similar to white noise that has been shown to muffle noses that would normally disturb sleep.

Like all good humidifiers, the SimpleTaste humidifier has a water filter to remove impurities before turning the water into a mist and diffusing it into the air. This provides benefits to the people breathing the air as well as the appliance itself.

Does filtered water help a humidifier?

Removing the impurities before the water enters the rest of the humidifier keeps the moving parts clean. This is an ultrasonic humidifier that uses vibrations to turn the water into a mist. The filter keeps mineral buildup from accumulating on these moving parts.

The SimpleTaste Ultrasonic Cool Mist Humidifier Aroma Essential Oil Diffuser features a small sponge that holds the essential oils until they are ready to be diffused. You guessed it, filtering the water also keeps minerals out of the sponge and extends its life.

Finally, keeping minerals out of the diffused moisture also keeps them out of the air. Some ultrasonic or cool mist diffusers/humidifiers let the minerals and impurities leave into the air along with the moisture they produce. These impurities can sometimes be seen on nearby surfaces in the form of a white dust. People who suffer from asthma have a hard time breathing these impurities, too.

How long does the filter last?

The filter needs to be replaced every 500 hours that the humidifier/diffuser is used. If you refilled the water reservoir every time before it was empty and never let it stop running, this works out to just over 20 days on the highest mist setting. However, this will most likely not be the typical level of use. 1byone makes the recommended filters for SimpleTaste humidifier products.

Realistically the humidifier diffuser combo will probably need a new filter once a month. We included the replacement filters in the images below so that you can estimate the cost of owning the appliance over a period of time. The essential oils featured below are some of the most popular and have a variety of scents. If you have not used essential oils before or are looking for a new scent, check out this set.

Everlasting Comfort Ultrasonic Humidifier (6L)

Here are the major differences between the Everlasting Comfort Ultrasonic Humidifier and the SimpleTaste humidifier diffuser we just reviewed

  1. Higher capacity, 6 liters vs 4 liters
  2. Does not include a water filter
  3. Uses a tray rather than a sponge to hold essential oils

Capacity

With a larger capacity you will not need to refill as often. The manufacturer advertises that a full tank of water will last this humidifier for up to six days. While that sounds great from a convenience standpoint, it is unlikely that this setting puts out enough humidity to make a noticeable difference in air quality.

Filterless Humidifier Diffuser Combo

Everlasting Comfort does not design this appliance to use a water filter. On the one had, you do not have the expense of a filter that comes with the SimpleTaste version. However, expect the white dust on nearby surfaces that comes from adding unfiltered water to the air.

The manufacturer is aware of this problem with filterless cool mist humidifiers. They recommend using filtered or distilled water in the humidifier to avoid any issues.

Essential Oil Tray

The last significant difference is how essential oils are added to the appliance. Instead of a sponge, you put the oil into a tray. A small fan circulates air over the tray and carries the oil toward the mist leaving the appliance. Together, the moisture and essential oils diffuse into the room. If you like to switch between different essential oils often, this is the better choice.

It is much easier to clean out the essential oil tray with soap and water. If you want the clean the sponge from the SimpleTaste diffuser it will take some extra work to make sure the sponge is ready for a new essential oil.

Since there is no filter to buy, we have only included the humidifier diffuser combo and a great set of essential oils in the images below. They are all clickable links that will take you to the product listing on Amazon.com. Once you are there you can explore other product listings as well.
