Our Top Recommend Humidifiers for Home Use:

Now that you’ve taken a look at our quick list of best humidifiers, now let’s dive deeper into more detailed reviews.

Best Humidifiers to Buy for Home Use:

Our favorite humidifier is the Honeywell HCM350W Cool Mist Humidifier as it has a good selection of features and is affordable.

While a majority of humidifiers use a nozzle that emits a visible stream of mist, the Honeywell’s unit consists of a fan that distributes cool air invisibly. According to the manufacturer, this humidifier can increase the humidity level in a space by up to 40 or 60%.

Another thing you’ll love about this humidifier is the ease of setup. To get started, all you need to do is remove it from the package and place it on your preferred location.

Next, take out the water tank, and the water filter. Fill the tank up with water and soak the filter in cool water. All that’s left now is to place these two components back in the humidifier, plug it in and you’re good to go.

The tank of the Honeywell HCM350W has a capacity of 1 gallon. Despite the massive capacity, the humidifier doesn’t occupy a large footprint. Plus, you have the option of choosing it in black or white.

The only thing you have to be cautious about is its placement. Since it has to be plugged to operate, it should be placed in close proximity to an outlet.

Another noteworthy feature of the Honeywell is its performance. The manufacturer has incorporated state-of-the-art technology, which sanitizes tap water to kill germs. The humidifier also uses a wicking filter that ensures the mist quickly evaporates once it’s been released into the atmosphere.


  • It’s easy to fill
  • Has an intuitive user interface
  • It cools and moistens a space quickly
  • Integrated fan that distributes air effectively


  • Lacks an automatic shut-off control

Are you on a tight budget? You can still get a quality humidifier like the TaoTronics Cool Mist Humidifier. Despite its low pricing, this piece of equipment has most if not all of the essential features you’d look for in a humidifier.

For starters, it’s one of the most compact humidifiers on the market. Measuring 8.1 x 5.3 inches, the humidifier is small enough to be placed on a coffee table, counter or nightstand. The best part is, it comes in the conventional white color meaning it won’t overshadow other appliances or home decoration items. Apart from being compact, the humidifier is also lightweight.

It weighs a measly 3.52 pounds so you won’t have any issues moving it from one location to another. With the ever-increasing utility costs it can be challenging to lower your electricity bill if you keep adding appliances that rely on the same. Luckily, the TaoTronics is an energy-efficient model, being powered by a simple 30-watt motor.

And unlike the Honeywell that lacks an automatic shut-off feature, this humidifier comes with one. So whenever the water in the tank runs out or the desired humidity level is achieved, the humidifier automatically shuts off.

Another feature that sets TaoTronics humidifier apart is the LED display that shows the current humidity level and other parameters. At night, you can turn off the LED nightlights to get uninterrupted sound sleep.


  • Has a lightweight and compact design
  • LED display can be turned off for a restful night
  • Has an automatic shut-off feature
  • Available in multiple colors


  • Only ideal for small to medium-size rooms

If you’re purchasing a humidifier for a bigger room, the AIRCARE MA1201 Whole-House Evaporative Humidifier is an excellent choice. With a coverage area of 3,600 square feet, this humidifier is big enough to cater to a whole house or any large-sized room.

The humidifier is equipped with a 3.6-gallon tank that provides a runtime of 36 hours. As you might expect from its capacity, the humidifier takes a large footprint.

When assembled, it measures 20.5 inches high, 21.5 inches wide and 14.5 inches long. This makes it bulkier than other humidifiers. 

Luckily, it’s also equipped with wheels that make it easy to move from one location to another. Another thing we like about this humidifier is that it has 4 different fan speeds. You’ll be able to monitor its speed through the read digital display that it comes with. What’s more, you can use this control panel to set a specific humidity level, which the humidifier will work to maintain.

The humidifier comes with a 60-inch cord. This cord is long enough allowing you to set it up anywhere within your home. The Aircare is an evaporative humidifier that comes fitted with a wick filter. It circulates dry air through the saturated wick filter and then adds an invisible mist of air. The wick filter helps to trap any dirt particles from the water being evaporated.


  • Perfect for big-sized rooms
  • It’s easy to refill
  • Comes with an auto shut-off feature
  • Equipped with a high-capacity tank with a reasonable runtime


  • Filter needs to be changed from time to time

If you prefer a warm mist humidifier, the Vicks Warm Mist Humidifier is a great option. It has a sleek and attractive design that fits well into any room.

The dimensions of the humidifier are 14.2 x 12 x 7.8 inches with a weight of 4.5 pounds. Its water tank is incredibly easy to refill. It’s also easy to keep track of the water levels thanks to the transparent reservoir.

Another element we like about its design is the fact that it doesn’t have a filter like its cool mist counterparts. This means that you’ll never have to worry about the cost or hassle of cleaning the filter regularly.

Vicks Humidifier also has an automatic shut-off feature. This ensures that the unit doesn’t overheat in case you forget to turn it off. Its water tank has a capacity of 1 gallon, and it can operate for a continuous 12 hours.

Since it’s a warm humidifier, it operates by boiling water. The benefit of this mechanism is that the resulting mist of air is 95% free of bacteria meaning the humidifier can be set up in a bedroom, nursery and other sensitive spaces.


  • Affordable
  • Easy to clean and maintain
  • Transparent water tank makes for easy monitoring
  • Has a large coverage
  • Backed by a 3-year warranty
  • Auto shut-off feature when the reservoir is empty


  • Does not have a humidistat

Humidifiers have a bad rep for being inefficient, especially those that have extremely large water tanks. Some models also tend to fill spaces with heavily humidified air. But this is not the case with the Pure Enrichment MistAire Ultrasonic Humidifier.

It’s incredibly efficient as it comes equipped with a 1.5-liter water tank with a runtime of at least 16 hours. Essentially, it can operate all night or all day without having to be refilled. The humidifier employs ultrasonic technology to generate a purified mist, releasing it into the air efficiently. The benefit of using this technology is that it provides an ultra-quiet operation. 

It’s also equipped with a 360-degree nozzle, which ensures that the humidified air is released in all directions pre-determined by the user. This way, you’re sure that moisture is dispersed to areas of the space where it’s needed and directs it away from areas where it’s not needed.

Despite its somewhat small water tank, this humidifier prides itself on having a continuous runtime while still providing ample coverage for a medium-sized room that’s up to 250 square feet. Another feature you’ll love about the humidifier is that it has an optional night light mode. This component provides a soft glow, enabling the humidifier to double up as a night light for toddlers and any other individual who’d want one.

It also has auto shut-off capability. Even if it’s rated to work for up to 16 hours, the device automatically shuts down once it runs out of water. The only drawback to using Pure Enrichment is that it does not have a water filter, meaning you’ll have to use pre-filtered water.


  • Has a compact, space-saving design
  • Comes in a sleek design
  • Efficient at cooling and moisturizing air
  • Provides a quiet operation


  • Lacks a water filter
