Best Humidifier for Bedroom Use to Breathe Easier at Night

When temperatures drop and humidity levels dip, especially in the winter months, cool and dry air in your home can be devastating to your sinuses and skin. But you probably don't just want to sit there and suffer through chapped lips, cracked hands or even nosebleeds at times. If your home has persistently dry air, or you just want to fight the occasional cold-particularly at night, the best humidifier for bedroom use can do wonders to enhance your air quality and health.

What Does a Humidifier Do?

Quite simply, a mist humidifier adds moisture to dry air. The moisture is released as either cool mist, water vapor or ultrasonic frequencies that prompt water droplets into a chamber to increase humidity. According to Michael Breus, Ph.D., popularly known as The Sleep Doctor, the best humidifiers can help to improve dry throats and mouths and have been reported to decrease congestion for better quality to your sleep. More so, if you keep plants at home, a quality humidifier should help to keep your green babies thriving.

This humidifier has a 1.5-gallon water tank, providing run times between 20-36 hours for rooms up to 750 square feet. If you're looking for a powerful ultrasonic cool mist humidifier, the LV600HH is almost a no-brainer for a consistent humidity level in your house throughout the year.

It comes with a one-gallon tank that can run within a 12 to 30-hour range before requiring a refill. It has a built-in humidistat that allows you to track and find the desired humidity level for your room. The TT-AH001 also has an auto-off feature, automatically shutting off the appliance when water runs out. This cool mist ultrasonic humidifier also comes with filters, which the manufacturer recommends changing every 4 to 6 months.

Perhaps its biggest draw is the exceptionally quiet operation, making it ideal for a small bedroom or a baby's room. Despite the more compact size, it still disperses mist quite well. It comes with a night light that you can leave on or sleep mode when you want to turn off its lights completely. The TT-AH001 also looks pretty stylish and is available in black, white and grey variants.

If you mostly want to resist the occasional cold, instead of running a humidifier throughout winter, warm-mist humidifiers are an excellent choice.

  • Compatible with Vicks inhalants.
  • Easy to clean.


  • Requires cleaning frequently.

Why Should You Consider a Portable Humidifier for Bedroom?

As opposed to whole-home humidifiers, humidifiers for bedroom use are easy to use and usually reasonably priced. Despite the obvious size difference, these portable units are still powerful enough to help you cut down on dry air. Using the best humidifier for bedroom can prevent dry sinuses, chapped lips and hands, while also reducing static electricity.

As much as winter might be the most popular time to use a warm mist humidifier in your bedroom, using your air conditioner in the summer can equally wreak dry air havoc. Therefore, running a humidifier all year round could help when your home's humidity level falls under the ideal 30-60 percent range. You can always use a hygrometer if you're unsure about your house's humidity. 

Factors to Consider in the Best Humidifier for Bedroom

1. Type of Humidifier

Choosing between a warm and cool-mist humidifier is arguably the first thing you'll have to decide. Both types effectively work by adding moisture into the air, but their applications tend to differ ever so slightly.

a). Cool-Mist Humidifier

Cool mist humidifiers are more suited to homes with children and pets since there's no risk of burning from the heating element. Furthermore, these humidifiers can also help shrink nasal passage swellings, making it easier for you to breathe. There are two variations of cool mist humidifiers:

  • Evaporative humidifiers- use a fan to blow air through a wet wick, cooling the air as it picks up the moisture from the wick.
  • Ultrasonic humidifiers- use a nebulizer (a small vibrating diaphragm) to create the cool mist. Ultrasonic modifiers don't have fans, hence they are usually quieter.

b). Warm Mist Humidifier

Warm mist humidifiers draw on a heating element to boil water which creates the warm mist. Also known as steam vaporizers, these are better suited when temperatures drop. They are cheaper than cool most humidifiers, although they also consume more energy. It's worth noting that warm mist humidifiers can cause nasal passages to swell, which makes breathing more difficult. While not completely unheard of, it would be best to avoid using them to relieve cold symptoms.

Furthermore, they're not particularly the best for homes with children since the hot water in the humidifier tank can burn a child or pet if the humidifier leaks or tips over.

2. Size

Generally, the size of the humidifier you'll opt for largely relies on the size of the room you want to add moisture to. For the best humidifier for bedroom, you'll probably go for a portable unit, also known as tabletop humidifiers, which more often than not are placed on a nightstand or desk.

Portable humidifiers are compact, with smaller water tanks that need to be refilled more frequently. To put that into perspective, most portable humidifiers hold the same capacity as a water bottle. On the other hand, they are much more affordable and be moved from one room to the other quite easily.

3. Water Tank Capacity

Water tank capacity relies on the size of the humidifier. If you're looking to use a humidifier all night or all day-or both-you'd be better off going for a product with a large enough capacity. Whatever the case may be, it's important first to check at the manufacturer's estimated run time to have an idea of how frequently you'll need to refill the tank.

You can also opt for a humidifier with a removable tank, making it very easy to refill from a kitchen or bathroom faucet. While at it, you'll also have to consider how heavy it'll be when you're carrying it back. If it's too heavy to be practical, you can always bring water to the humidifier with a jug or pitcher.

4. Run Time

You'll also have to consider how long the humidifier can run before it needs refilling. Some can operate for a couple of hours, while others can run for a full 24 hours. If you opt for a humidifier that needs frequent refilling, it would be best to get one with an auto-off feature. This ensures the humidifier will stop running as soon as the water runs out.

5. UV Filtration

Moist, humid conditions can easily quickly turn into breeding grounds for bacteria, pathogens and mold. As such, some humidifiers come with UV light. A specialized light filtration system eliminates microbes that could be breeding in the humidifier's tank while also preventing them from being emitted into the air with the mist.

6. Humidistat

A built-in humidistat is a nifty feature to have on a humidifier. It monitors the room's humidity and regulates the appliance accordingly. As much as this is not particularly necessary, it helps prevent releasing excess moisture into the air, which can fog up windows or leave a musty odor in the room.

7. Ease of Cleaning

Most manufacturers and experts recommend cleaning your humidifier at least once every week. This prevents the growth of microbes, bacteria and mold. Ensure you go for a humidifier that is simple to disassemble and easy to clean since you'll be doing it pretty often.

Frequently Asked Questions on Humidifiers

1. When should I use a humidifier?

Humidifiers are mostly used in the cold season, thanks to their effectiveness in easing chapped lips, scratchy throats and parched skin. Some people also use these devices to relieve discomfort caused by mold or pollen, mostly in spring and summer. As such, it's not completely inconceivable to keep a humidifier running all year round. That said, the best time, arguably, to use a humidifier is while you sleep at night.

2. How close should the humidifier be from my bed?

If you're dealing with a cool-mist humidifier, you don't have to worry much about this. However, a warm-mist humidifier should be placed far away enough from the bed for safety reasons, particularly at night. You should take even extra caution if you're using the humidifier in a kid's room.

3. How do I clean a humidifier?

The general process of cleaning a humidifier is to "empty, rinse and dry the base tray or reservoir before refilling." You can even disinfectant the appliance with a bleach solution if you want to be thorough. However, ensure you refer to the instruction manual before you do so.
