We live in New England, where the winters are cold and the indoor air is dry
from the heating system. I am also susceptible to respiratory illnesses such
as colds, flu, bronchitis, and pneumonia in the winter, so using a humidifier
is necessary for both health and comfort.
We have found that ultrasonic humidifiers, which we prefer for reasons I'll go
into below, tend to last only a few years. So, we have tried a variety of
brands and models. The
Levoit LV600S Smart Hybrid Ultrasonic Humidifier
we purchased a month ago is our favorite by far.

The Levoit LV600S is the New York Times Wirecutter's top pick as
The Best Humidifier of 2023. We love ours!

How to Choose a Room Humidifier
After purchasing multiple humidifiers over the years and doing a lot of
product research before each purchase, we've gotten good at choosing a good
one. Here are the key considerations when shopping for a humidifier.
Type
There are four main types of portable room humidifiers we considered, which
differ based on how the humidity is generated.
Warm mist humidifiers heat the water to create the vapor,
i.e., steam. They're great for cold, dry winter climates like ours, and the
heat cuts down on germs and bacterial contamination. We have found that they
can create a lot of humidity — sometimes too much if you don't keep an eye on
the moisture levels. However, warm mist units tend to be noisy, use more energy, and be more difficult to clean than cool mist models. Also,
if you have children or pets, a reservoir filled with boiling water may not be
the safest choice.
Cool mist units increase the humidity of the room without raising the
temperature, so they're ideal for dry, warm climates. They tend to be pretty
energy efficient. The units emit a humming sound that may bother some people,
while others may experience it as "white noise" that is acceptable. We have
found that they can be prone to developing mold and mildew and need to be
cleaned more frequently than other types.
Evaporative humidifiers are a subset of the cool mist category. These units create
vapor by using a fan to blow air through a moist filter, speeding up the
natural process of evaporation, and that vapor is emitted or blown into the
room. Like other cool mist models, evaporative humidifiers are safe for
children and pets (because the mist is cool or room temperature), and are
energy efficient. The filter needs to be changed regularly.
Ultrasonic humidifiers use high-frequency sound vibrations
to break the water into droplets, which are then expelled into the air. These
units are very energy efficient and extremely quiet, making them a great
choice for bedrooms. Many models offer the option of producing cool or warm
mist. They may or may not require a filter.
After having tried several types, we prefer an ultrasonic.
Size of Room
As with choosing an air conditioner or space heater, it's important to choose
a model designed for rooms of a similar size to the one for which you are
purchasing the unit. The power of whatever is creating the mist determines the
volume of space the unit can humidify.
Reservoir Capacity
The size of the reservoir determines how long the unit can produce vapor (not
how much it can produce) and, therefore, how often you will need to refill it.
For that reason, it's important to make sure the reservoir is at least large
enough to continue producing mist throughout the night, while you are
sleeping.
I look for a large-capacity reservoir that I can fill only once or twice a
day.
Ease of Filling
A top-fill reservoir is much easier to fill than a bottom-fill tank. A
top-fill reservoir can be filled without removing it from the base unit,
whereas a bottom-fill reservoir must be lifted off the base, carried to a
faucet, and inverted under the tap to fill it. This can be messy (the water
drips) and, if you have a large tank, heavy after you fill it.
Our last ultrasonic humidifier had a bottom-fill reservoir, and we hated it.
The sink in our master bedroom's en-suite bathroom is old and small, and we
couldn't get the opening of the reservoir under the faucet. That meant we had
to carry the dripping tank to and from the kitchen.
Also, since a humidifier should only be on when the reservoir is in place, we
had to remember to turn off the power, remove the tank, fill it, replace it,
and turn the unit back on.
Ease of Cleaning
It's important to clean your humidifier frequently to avoid breathing vapor
filled with germs, mold, and mildew. So, choosing a model that is easy to
clean has become one of our top criteria.
Consider the size of the reservoir opening (can you reach inside easily?), and
the size and number of corners, nooks, and crannies in the base and tank.
Controls
Consider whether you want manual or automatic controls or a choice. For
example, you might want to manually set the rate at which the unit produces
mist (regardless of the ambient humidity level), or you might want to set a
target humidity level and let the unit automatically start and stop producing
vapor as needed to maintain that humidity.
If you live in a climate where the humidity is fairly constant, manual
controls are fine. However, if you live in an area with more variable weather
conditions, like New England (where the saying goes, "If you don't like the
weather, just wait a minute"), a unit with an automatic setting to maintain a
target humidity level will be important.
Price of Consumables
Some types and models require water filters, mineral absorption pads, or other
consumables, some of which may be optional (like the aroma pads for our new
unit) or may depend on whether you have hard or soft water in your house.
It's important to determine which consumables, if any, are required, how often
they will need to be replaced, and how much they cost, to help you determine
the total cost of ownership over the expected lifetime of the product.
Customer and Expert Product Reviews and Recommendations
When my husband and I are researching products like humidifiers, we always do
our due diligence. We comb through Amazon product reviews and look to expert
product reviews and recommendations such as those from Consumer Reports and
The New York Times Wirecutter to help us narrow our short list of
candidates and finalize our product selection.

Why We Love the Levoit LV600S Smart Hybrid Ultrasonic Humidifier
After trying so many different humidifiers over the years, here are the
reasons we love our new Levoit LV600S humidifier.
The NYT Wirecutter's Top Pick
This ultrasonic humidifier topped our list of candidates after we read the New
York Times Wirecutter article "The 6 Best Humidifiers of 2023" and saw that the Levoit LV600S Smart Hybrid Ultrasonic Humidifier was
their top pick. That was a compelling expert recommendation, and when we
looked at the Amazon customer reviews for this product we were extremely
impressed with the overwhelmingly positive feedback.
Hybrid Warm/Cool Mist Ultrasonic
If you're not sure which type to buy, the Levoit LV600S Smart Hybrid
Ultrasonic Humidifier gives you the best of all worlds. This model defaults to
cool mist, but there is a Warm Mist button that cycles through your choice of
warm mist settings (low heat, medium heat, high heat, heat off).
For example, if someone is sick and has chest congestion, you can select one
of the warm mist options to help them breathe easier.
The brand's "exclusive" Warm Mist mode claims to have improved mist dispersion
and a powerful output: "Set at 550ml/h, the warm mist function generates
temperature variation, boosting air circulation for 4× faster relief from
discomfort" vs. cool mist.
There is also no risk of being scalded by hot vapor, as the mist is released
at a safe temperature of 86-120 °F.
Designed for a Large Room
With its powerful 550ml/h output, the Levoit LV600S is designed to humidify an area as large as 753 square
feet.
Large Reservoir
One of the things we love about this model is the large 6-liter capacity
reservoir. We keep our humidifier cranking 24/7 during the cold, dry, New
England winter months, and although we top up the water daily, the tank is
usually still about half full after 24 hours.
Depending on the settings, the manufacturer claims the unit can produce
humidifying mist for up to 50 hours on a single tank of water.
Easy to Fill
The Levoit LV600S is a top-fill model. So, instead of having to turn off the
power, remove the water tank, carry it to the sink, turn it over, unscrew the
cap, maneuver it under the tap, fill it, replace and tighten the cap, carry it
back to the base, and seat it properly before turning the power on again, as
we did with our previous model, we can just lift the lid, top up the tank with
filtered water from our Brita pitcher, and replace the lid. Easy peasy!
Easy to Clean
This is by far the easiest-to-clean ultrasonic humidifier we have owned. The
large opening in the tank makes it easy to reach inside, and the interior
corners of both the base and the water tank are very accessible. The cleaning
brush that comes with this model is also larger than those from our previous
units.
Ease of Operation
The Levoit LV600S has simple, intuitively labeled buttons on the front control panel and a large, easy-to-read, digital display (which is turned off automatically in Sleep Mode).
Automatic Humidity Control
Since we live in New England, the ability to have the unit adjust the volume
of mist output automatically to maintain a desired target humidity level is
essential. We love this set-it-and-foreget-it mode. However, you can also set
the mist output level manually, if you prefer.
Reasonably Priced Consumables
The
Levoit Replacement Mineral Absorption Pads
should be replaced every 2–4 weeks depending on the hardness of your tap
water. A pack of 10 costs $9.99 on Amazon at the time of this post's
publication. You can also find
less expensive replacement pads
that claim to be compatible with this model.
The
Levoit Water Filter Sponges
should be changed about once a month, depending on the water hardness in your
area. At the time of this article's publication, a 10-pack costs $9.99 on
Amazon.
There are also optional Levoit Aroma Pads that can be used with essential oils and
placed in the Aroma Box compartment at the back of the base. The mist will
diffuse the aroma when the humidifier is in use. A pack of 16 costs $9.99 on Amazon as of this writing.
Extremely Quiet
At a noise level of less than 28dB, the default unheated, cool mist mode is
practically silent, which we love. The sound increases when the Warm Mist
settings are used to heat the water, but this model is still extremely quiet
compared to our previous humidifiers.
Sleep Mode
The Sleep Mode turns off the lighted controls display and changes the mist
setting from a manual mode (if applicable) to an automatic mode and uses the
humidity sensor to automatically adjust the mist level to maintain 50-60%
relative humidity.
Sleep Mode also turns off the warm mist, if applicable, to reduce noise, but
you can press the Warm Mist button to turn it back on if desired.
My husband can't sleep well unless our bedroom is completely dark, so being
able to keep the display turned off is a great feature for us. We keep our set
to Sleep Mode all the time unless we need to change a setting manually, which
makes this appliance much more unobtrusive.
Minimal "White Dust"
After running our Levoit LV600S nonstop for the past month and filling it with
filtered tap water from our Brita pitcher, we still haven't seen any sign
of the dreaded mineral residue on our furniture or floors.
Timer
Although we have not yet needed to use it, you can set a timer to
automatically shut off the unit after a preset interval (between one and 12
hours).
Memory Function
This model will remember your Mist Level, Humidity Level, Warm Mist, and Wi-Fi
settings even when the unit is turned off or unplugged. It will not remember
your Sleep or Timer settings, however, and the display will turn on
automatically when the unit is turned back on.
Aroma Box
At the back of the base, there is a compartment called the Aroma Box. You can
pull it out, put 8–10 drops of essential oil onto an Aroma Pad, place the
scented pad into the compartment, and replace it. This will lightly scent the
water vapor. We have not tried this yet.
“No Water” Indicator With Auto-Shutoff
If there is no water in the tank, this indicator will blink 10 times and the
humidifier will shut off automatically. The indicator lights up when the water
tank is removed and remains on until the tank is re-seated on the base.
Mobile App
What makes the Levoit LV600S Smart Hybrid Ultrasonic Humidifier "smart" is
that it is Bluetooth- and VeSync-enabled. VeSync is a smart home app that
allows you to control connected devices remotely from anywhere.

app lets you
control your humidifier and other VeSync-enabled
devices from your smartphone.

We only started using the app this week, and it's a great option with an
extremely intuitive, easy-to-use interface. It's also nice to know that we
will be able to control our humidifier remotely when we travel.
The app allows also you to access additional smart functions including a
sophisticated Plant Mode and is compatible with Amazon Alexa and Google
Assistant for voice commands.
Sleek Design
Although appearance is less important to us than function and features when we
choose an ultrasonic humidifier, this one has the advantage of looking
streamlined and unobtrusive and doesn't detract from our home decor. A nice
bonus!
Helpful Humidifier Tips
Optimize the Humidity Level
If you live in a climate with cold winters, keep the humidity level low enough
so the mist doesn't condense on your windows (and potentially rot the wood
window frames).
Consider a Standalone Indoor Hygrometer
A humidifier's built-in humidity sensor (humidistat) measures the humidity in
the immediate vicinity. For a more accurate measure of the room's humidity, we
put an inexpensive indoor hygrometer
on the far side of the room and set the humidifier's target humidity so that
our desired humidity level displays on the hygrometer.
Protect Against Possible Leaks
The only time we had an ultrasonic humidifier leak, it was the result of user
error. (It had a bottom-fill tank and when we refilled and replaced it on the
base, we didn't seat the reservoir correctly, so the water leaked onto the
table.) So, as a precaution, we now put our ultrasonic humidifiers on an old
plastic cutting board on top of a
sturdy plastic 12-gallon lidded storage container. The cutting board provides a stable surface for the unit to sit on, and the
interlocking flaps at the top of the crate are not water-tight, so if there is
ever a leak, the water would fall through the interlocking flaps and be
contained inside the crate with no risk of damaging our hardwood floors.
If you want to keep the humidifier manual and consumable supplies (e.g.,
filters) next to the humidifier, as we do, put them in a zippered plastic
freezer bag to keep them dry and protect against possible leaks.
Use Distilled or Filtered Tap Water
If your tap water is hard, you can cut down significantly on the dreaded white
mineral dust (the residue from the minerals in the water after the emitted
mist evaporates) by using distilled or filtered water. We keep a
Brita water filter pitcher
next to our humidifier and use the filtered water to refill the reservoir.
In fact, the manufacturer of our model recommends that all users use distilled
water or filtered water to fill the Levoit LV600S Smart Hybrid Ultrasonic
Humidifier instead of tap water, which they say "might leave white dust and
grow mold."
Give the Gift of Health and Comfort
If you know someone who lives in a cold or dry climate, has respiratory
issues, or gets colds easily, the Levoit LV600S Smart Hybrid Ultrasonic
Humidifier would make a great gift!
