Best Humidifier For Large Bedrooms Reviews 2022

A humidifier is used to increase humidity level in the room. When humidity level goes down, dry air enters the nostrils, causing trouble breathing. During wintertime, when windows are closed and heating systems dry out rooms further, a humidifier becomes essential in preventing sinus infections and throat problems. Choosing a right humidifier can be tricky though with so many brands available in stores. We have put together a list of best humidifiers for large bedrooms based on their performance, reliability and user experience.

2.  Honeywell HUL520W Mistmate Cool Moisture Humidifier with Filter – 1 Gallon

Honeywell HUL520W is a great humidifier for bedrooms and offices. It features automatic, adjustable humidity level control along with electronic controls. The unit delivers 3 comfort settings for low/medium/high fan speeds and 2 moisture output levels that can create ideal conditions in a room up to 500 square feet. It also comes equipped with two filters – foam filter captures dust particles while activated carbon filter reduces common household odors from pets , cooking, etc. The Mistmate requires filter replacement, but it’s very easy to find and inexpensive. Single tank design is easy to refill when empty without having to carry the whole unit somewhere.

The Honeywell HUL520W humidifier is a great add-on for your central heating system , especially when you use forced-air furnace in the house or office. It will work well in even larger rooms where humidity needs to be increased. The only downside we found with this model is that it can get a little loud when you set it on high fan speed (but that’s a common issue with fans) – so if you can’t tolerate white noise, this model might not be for you.

3.  AquaOasis™ Cool Mist Humidifier

AquaOasis™ cool mist humidifier is very compact unit that can easily fit on any desk. It provides whisper-quiet ultrasonic operation along with 2 output settings for small or large rooms. The compact design makes it perfect for bedrooms, home office, dorm room and more. What we liked the most about AquaOasis cool mist humidifier is its effective antimicrobial material which prevents growth of mold and mildew as well as bacteria inside the reservoir . In addition to being a great humidifier, it also doubles as an aromatherapy diffuser – just add few drops of your favorite essential oil to enjoy its benefits throughout the day!

The AquaOasis cool mist humidifier requires regular cleaning and filter replacement – both aren’t cheap to replace. Also, this unit tends to leak if overfilled or used on high mist settings – that’s something you need to keep in mind when operating it. In terms of performance, AquaOasis humidifier doesn’t really stand out from the crowd – it does an average job at best and we recommend using it only as a cool mist humidifier for medium-sized rooms (not suitable for large spaces).

  • Compact design
  • Inexpensive
  • Requires regular cleanings and filter replacements

Buying Guide

Before buying humidifier for your home, make sure to pay attention to the following features:

Area Coverage

Some products can cover larger areas while others are suitable for small spaces. If you live in a big house, buy a humidifier that is suitable for large rooms. Otherwise, if you have several rooms or an entire floor that needs extra humidity, opt for more powerful unit with larger water tank. This way you won’t  have to refill it all the time! Ease of Use Some models come with easy-to-use control panels or touch-sensitive displays which will allow you to operate them without any additional effort. Noise Level Remember that these products are designed to provide quiet night sleep so don’t forget to pay attention to how loud the unit is. Most of them should be pretty quiet (less than 50 dB) but some models can get pretty loud, so check reviews before buying!

Auto Shut Off

Some humidifiers come with an auto shut-off feature so the water level won’t go too low or high and you will not have to refill them manually every day. And if you forget about refilling it, don’t worry – they switch off automatically once there is no more water left in the tank.


This feature adjusts the humidity levels inside your home and switches off the humidifier once this level is reached. This saves electricity and prevents dry air resulting from constant running of a humidifier.

Filter​s Some humidifiers have antibacterial filters which kill any mold or bacteria in the water. This is a great feature especially if you suffer from asthma, allergies or other breathing problems.

Tank Size

If you plan to use your humidifier for more than one night, make sure to choose a unit with large tank capacity. Remember that most of these products need refilling once per day and replacing tank can be a hassle if it’s too small. 


The price of humidifiers varies depending on features and size, but there are plenty of affordable options that won’t break your bank! As for me, this Honeywell Warm Moisture Humidifier offers the biggest bang for your buck: it has 1 gallon tank, rotating nozzle, auto shut-off feature and timer – for just $ 50! So if you suffer from dry skin or irritated breathing, I strongly recommend buying this humidifier !
