Things to Consider

In this guide, we look at the reasons behind the popularity of HoMedics humidifiers, the key parameters that will help you to identify the right product for you, and the maintenance required to improve performance and extend longevity.

Why HoMedics?

HoMedics is a reputable brand that has been in the wellness business for a long time, making products such as air purifiers, humidifiers, fitness, and blood pressure monitors, filters, sleep aids, and scent diffusers.

Their humidifiers come in varied sizes, coverage areas, and functionality to suit your needs: you can choose portable or large units depending on the size of your intended space, and opt for cool mist or a combination of warm and cool mist models for versatile performance.

HoMedics humidifiers use ultrasonic technology to generate ultra-fine mist that is safe for usage around children, and that results in quieter operation.

Their products are powerful yet affordable.

Features to consider while choosing a HoMedics humidifier

Below is a breakdown of the most important features to consider before buying a HoMedics humidifier.


HoMedics humidifiers mainly incorporate ultrasonic technology, and they come in cool mist types like the HoMedics UHE-CM18 and the HoMedics UHE-CM65, or as versatile units such as the HoMedics UHE-WM85 that combine warm and cool mist capability.

Instead of using fans, ultrasonic units use high-frequency vibrations to generate an ultra-fine mist for distribution in your room. This makes them quiet and, with an average of 30 decibels of noise output, ideal for babies and bedrooms.

Coverage area

As you may have deduced from our review of the best HoMedics humidifiers, different models are designed to cover different sizes of rooms. For instance, the portable HoMedics HUM-CM10 is ideal for personal spaces and cubicles,

whereas the HoMedics UHE-WM250 is suitable for large rooms with coverage of up to 400 square feet. This is why you should confirm the coverage area before making your decision to ensure your intended humidifier can sufficiently protect your space without overworking.

Water tank capacity

The water tank capacity will determine the coverage area and runtime of your HoMedics humidifier. Large capacity can hold more water that can be released in high amounts of vapor to distribute in a large room and fuel the unit for several hours without requiring refilling.

The HoMedics UHE-CM65 has a 1.4-gallon tank with coverage of 300 square feet and runtime of up to 65 hours while the HoMedics UHE-WM250 has a water tank capacity of two gallons that facilitates coverage and runtime of up to 400 square feet and up to 120 hours respectively.

Comparatively, the HoMedics UHE-CM18 has a 0.5-gallon tank that increases humidity levels in medium-sized rooms for up to 25 hours without requiring refilling.


Runtime refers to the period that a particular humidifier can operate on a full tank without the need to refill. As stated above, the capacity of the tank determines the length of runtime, with a larger tank extending the period of operation.

The runtime will also vary according to the speed and volume of mist output. Water will deplete faster at high speed and volume, so the unit’s runtime will shorten.

Dimensions and weight

The HoMedics humidifiers we have features are designed for various sizes of rooms. That explains why they come in compact and portable designs that can be moved from one room to another or conveniently set up in a room without taking up plenty of space.

The most portable models in our list are the HoMedics HUM-CM10 with dimensions of 9.75 x 6.4 x 4 inches and weight of 5.4 ounces and the HoMedics UHE-CM18 that measures 8.8 x 8.8 x 10.4 inches and weighs 3.25 pounds.

Extensive coverage typically requires large water tanks, which increase the size and weight of the humidifier, forcing you to choose between the size of coverage and the weight and dimensions.

While this compromise is common with other brands, it is not the case with HoMedics humidifiers that cover broad areas yet remain compact. Another reason for this may be usage of ultrasonic technology, which eliminates the need for fans and subsequently reduce the overall size and weight of the unit.


The duration, terms, and conditions of the warranty differ from one model to another, with most of the featured HoMedics humidifiers offering warranty of one year. Reviews such as this one and buyer feedback on Amazon will help you to familiarize yourself with the features,

performance, and customer support for your intended unit. It will also help you to differentiate between products that work with essential oils and others like the HoMedics UHE-OC1 that advises against it to avoid voiding the warranty.

Extra features

Auto shut-off: This is an essential safety feature that protects your humidifier by turning off the unit when water is depleted to avoid damage from overheating.

Controls: They may come in the form of buttons like the one on the HoMedics HUM-CM10 or as electronic controls with programmable settings and digital display such as the ones found in the HoMedics UHE-WM85 and the HoMedics UHE-WM250.

Filters: HoMedics humidifiers do not use filters. Instead, they protect both you and the humidifier by using the warm mist to prevent growth of mold and mildew, incorporating clean mist anti-microbial technology to emit vapor devoid of allergens, and including demineralization cartridges that prevent buildup of mineral deposits. These alternatives prevent long-term costs on regular filter replacement.

Night lights: One selling point of HoMedics humidifiers is their optional nightlights, which allow you to turn them off whenever you wish. Some of their products come with multiple-colored nightlight, like the HoMedics UHE-CM18, which features 7-color nightlight, for a wider range of options.

Timer: This is a convenient feature that allows you to schedule increase of moisture levels to your preferred time to save power.

Oil diffusers: The HoMedics UHE-CM18 and the HoMedics UHE-WM250 allow you to diffuse medical inhalants (to relieve respiratory problems) as well as soothing scents and essential oils that add fragrance to your room and create a refreshing and calming ambiance.

How to maintain a HoMedics humidifier

Consider using distilled water to reduce the buildup of scale and deposits and growth of bacteria.

Clean your humidifier weekly with a mixture of lukewarm water and white vinegar, and then scrub off any residue with a soft-bristled brush before rinsing the reservoir and the base of the unit. Other parts should be spot-cleaned only.

If your humidifier comes with a filter, replace it regularly as advised in the manual.

Before adding essential oils, confirm whether your HoMedics humidifier is compatible with them in order not to void the warranty or damaging your product.


What’s the average noise level of these devices?

Ultrasonic humidifiers use high-frequency vibrations to generate a fine mist for dispersion in your room instead of the fans featured in evaporative units. This results in whisper-quiet operation, with minimal pleasant white noise that can lull babies to sleep. Such humidifiers produce an average of 30 decibels of noise, which is quieter than a running computer.

Which model can be used with essential oils?

The HoMedics UHE-CM18 comes with an essential oil tray and three essential oil pads while the HoMedics UHE-WM250 includes essential oils in its starter kit package, so you can diffuse them to add a pleasant fragrance to your room. Models that emit warm mist are typically better at diffusing essential oils because they first warm them.

What is a demineralization cartridge for?

Demineralization cartridges are commonly found in ultrasonic humidifiers such as the HoMedics UHE-CM65, which do not use a filter. The cartridges filter calcium, lime, and other mineral deposits in water to prevent scale build-up or release of the white dust into the atmosphere. This improves your air quality and lengthens the lifespan of your unit.

Our Verdict

In addition to versatile cool and warm mist functionality, the HoMedics UHE-WM85 boasts of broad coverage and runtime of up to 65 hours, programmable humidistat, and LCD digital readout of mist temperature and the current humidity levels in your medium or large-sized room.

The HoMedics UHE-CM18 appealed to us with features such as a 360-degree oscillating nozzle, protective Clean Tank technology, a seven-colored nightlight, and compatibility with essential oils for a calming and rejuvenating ambiance.

The HoMedics HUM-CM10 is our Budget Pick and the most portable product in this review, It comes with a USB adapter and 120V AC adapter to plug the unit into a wall outlet or a laptop, three bonus wick filters and simple single-button operation, but its compactness is its greatest advantage because it makes this humidifier easy to move and set up in any space in your house or office.
