How Does an Air Purifier and Humidifier Combo Work?

It isn't unusual for people to purchase an air purifier as well as an air humidifier. But why invest in two separate devices when one can do the job?

Of course, a few years back, the air purifier and humidifier combo didn't exist. However, now you can easily find them in the market. Some people still don't know such a combination is available. So, hopefully, this article has made you a more informed person.

An air purifier and humidifier combo works by not only purifying the air (by removing certain particles and contaminants) but by also making sure the humidity in an area remains at a healthy level.

This means that not only will your household be breathing clean air, they will also not have to worry about poor humidity-related issues such as dry skin, rashes, and an aggravation of certain ailments.

When humidity levels are low, the mucous membrane becomes irritated and loses its effectiveness. This leads to increased chances of falling ill due to a particular bacteria or virus. Proper humidity levels also help keep colds away during winter.

With an air purifier and humidifier combo you are:

  • Breathing Clean Air

  • Keeping Your Immune System in Check

  • Getting Rid of Certain Viruses, Bacteria, and Contaminants

  • Reaping the Benefits of Two Machines Through a Single Device

  • Saving Space

As there are quite a number of these models out there, you should do your research to see which are the best.

We hope to share such valuable information with you through this article. To make an informed buying decision, you need to know about specific features and specifications that matter when selecting such an air purifying and humidifying unit.

How to Choose the Ideal Model?

So, you are interested in buying this type of product?? Where do you begin? What are the factors you need to keep an eye out for to choose an excellent option for yourself?

Let’s answer these questions and more!

The features you should be looking for when shopping for an air purifier and humidifier are:


You will need to look into how efficient the unit is. The efficiency, in this case, means the extent to which a model can get rid of smoke, odors, allergens, etc and also add moisture into the air.

Generally, a combo unit boasting 90% efficiency is good for handling cooking smoke, pet dander, and odors. However, if you are interested in something stronger, a unit boasting 99% (or higher) efficiency is ideal for getting rid of allergens and certain pollutants to ensure the safety of your household.

Filtration System

Related to efficiency is the filtration system featured in the combo unit. A good start is a combo unit with a HEPA filter. However, you will also find ones that have carbon filters and electrostatic filters. Depending on the kind of filter being used, the air purifier and humidifier will offer different benefits.

HEPA and activated carbon are great for removing up to 99.97% of air contaminants found indoors and can keep odors away from your nose. Similarly, UV sanitizers zap viruses and bacteria by using UV light

If someone in your household has serious medical issues (especially breathing problems and allergies), you should talk to your doctor about what kind of filtration system you should opt for.

Area Coverage

An air purifier and humidifier isn’t going to do you much good if it doesn’t cover the amount of area you need. It will also be a waste of money.

A good way to make sure you purchase the right combo unit is by measuring the room (in square feet) you want to cover and then seeing which device can cater to your needs.


No one likes noisy machines. However, these units are known to produce noise because a single device is doing the work of two. But that doesn’t mean you won’t be able to find a unit that makes as little noise as possible.

So, before you decide on a purifying and humidifying combo unit, you can test it out to see the level of noise it produces. If you are shopping online, you can also go through the reviews to see what others have said.


When it comes to investing in technology, you want your life to become more comfortable. The same holds true for when you are out looking for a combo unit to purify and humidify the air.

Try and opt for a unit which is easy to maintain. It shouldn't require you to change the filters too often. It should also be easy to clean. Again, reading through reviews can help.

Review of the Best Air Purifier and Humidifier Combos

Now that you have learned what is meant by an air purifier and humidifier, as well as the features you should look for before making a purchase, here is a list of some of the best combo units available.

These reviews are well-researched, to help you make an informed decision.

BONECO - Air Washer W200 Humidifier & Purifier


  • It Doesn’t Produce a Lot of Noise
  • The Knob Allows You to Set This Device in the Manner You Want
  • The Sleek Design Allows This Unit to Go Well With Almost Any Décor
  • With Some of the Parts Being Dishwasher Safe, Maintaining this Combo Device is Going to Be Quite Easy for You


  • Isn’t Good at Getting Rid of Odors and Smoke

Our Review

If you are looking for a stylish and efficient air purifier and humidifier combo, it doesn’t get better than the BONECO 2-in-1 Air Washer W200. That is why it is our best overall choice on this list.

It will look great in any room. Furthermore, it features a simple black control knob which you can use to switch between the device’s two mist output levels.

This unit draws air in through specially textured evaporative mats. These mats turn in the water, adding moisture to the air as well as removing pollutants. With a coverage capacity of 540 square-feet, it more than makes up for the price tag.

Also, this combo unit allows you to add essential oils to the mist being produced! You can easily make sure your household remains healthy throughout the year with this device. It is also effortless to maintain. Some of the parts are dishwasher safe. Talk about convenience! This device doesn't make a lot of noise during operating hours.

Now, this wouldn't be a proper (and helpful) review if we don't talk about some of the drawbacks of the BONECO 2-in-1 Air Washer. When it comes down to it, this combo unit isn't the best at getting rid of odors and smoke. So, while it can help you keep humidity levels in check as well as use essentials oils in the mist to aid with relieving certain ailments, it doesn't offer much in terms of odorless air for breathing.

Bottom Line

The BONECO 2-in-1 Air Washer W200 is the best overall choice on this list. This is due to its design, easy maintenance, and low noise production. It also offers large area coverage and allows you to use essential oils in the mist.

Sharp KC-850U

Sharp Triple Action Plasmacluster Air Purifier with Humidifying Function (254 sq. ft.), KC-850U


  • It Has an Elegant Design
  • Is Good for Getting Rid of Odors From a Room
  • Works Well to Get Rid of 99.97% of Pollutants in the Air
  • Has 3 Fan Speeds to Maintain the Type of Humidity You Prefer
  • Easy to Use by Offering Automatic as Well as Manual Operation


  • It Doesn’t Come with a Remote Control
  • The Noise Might Not Be Low Enough for Some Users

Our Review

The Sharp KC-850U is the runner-up on our list. This unit is another option for you to consider. It can work quite effectively and will cater to your air purifying and humidifying needs without trouble. A remarkable thing about this combo unit is that it features a HEPA as well as an activated carbon filter.

The HEPA filter used in this device is more than capable of getting rid of 99.97% of pollutants (at least .3 microns) in the air. This means the HEPA filter helps this unit get rid of bacteria, smoke, and dust. As for the odor, this is where the activated carbon filter will help. Such a filter can absorb the VOCs (Volatile Organic Compounds) which produce odor.

Furthermore, the Plasmacluster technology featured in this unit keeps humidity levels in check. Water molecules are split into negatively and positively-charged ions. They are then spread across the room to make it fresher.

With the Sharp KC-850U, you get both automatic and manual operation. There is also an indicator for clean/dirty air. You can choose from the three fan speeds to set the humidity levels. This device's automatic setting will adjust the machine itself after sensing the condition of the room. It doesn't produce a lot of noise. Do keep in mind it doesn’t come with a remote control.

Bottom Line

The Sharp KC-850U is our runner-up air purifier and humidifier choice. It features a HEPA filter to get rid of close to 100% of air pollutants. It also has an activated carbon filter, which ensures the room is odorless. This combo unit is easy to use and maintain.

  • The 1.6-Gallon Tank Capacity Allows This Unit to Keep Working for Quite a While, Without Those Annoying Refill Trips


  • It Does Produce Noise

Our Review

The KLARSTEIN Monaco Ultrasonic Humidifier is another awesome choice for you to know about. This unit has the honor of being our ‘Best for the Money' air purifier and humidifier.

It offers area coverage of 430 square feet with a 1.6-gallon tank capacity. The remote access ky accompanying this unit allows you to control this device the way you want from anywhere. It also features a bright LED display.

This unit provides you with fresh air when you need it. The process is accomplished by this unit's ability to transform water into a cool mist. The antibacterial filter ensures the produced mist is safe for your household to breathe in.

There is also a built-in timer which allows you to program this unit to humidify according to your needs. The 1.6-gallon tank capacity prevents you from refilling this unit repeatedly. With the remote access key, you can operate this unit from anywhere. The three power levels are there for you to change the functioning of this unit according to what is required.

Bottom Line

The remote access key enables you to operate this combo unit from anywhere. It is also very easy to use. There are three power levels for you to choose from to get the type of clean air and humidity you want.

Venta LW25 Airwasher 2-in-1 Humidifier and Air Purifier in Black


  • Offers You Heavy-Duty Humidification
  • It Doesn’t Consume a Lot of Electricity While Operating
  • Doesn't Make a Lot of Noise. So, it Can Be Used in Rooms for Kids
  • This is a Very Low-Maintenance Air Purifying and Humidifying Unit


  • It Doesn’t Have a Timer or a Humidistat
  • This Unit isn’t Great When it Comes to Cleaning Indoor Air of Pollutants

Our Review

The next device we have on our trusty list is the Venta LW25. This air purifier and humidifier works by drawing air over a set of disks. These disks rotate slowly and trap air pollutants. This device can help get rid of pollen, as well as dust from indoor air. The water inside this device then cleans the discs. This process leaves you with clean mist.

This unit is also fairly quiet during operation. It offers three output levels so you can get the level of humidity you want.

Another great feature about the Venta LW25 is that it doesn't require a lot of maintenance. You will only need to clean it once or twice a month. Don't be fooled by the compact size. This unit will cover an area of up to 400 square feet. It also doesn't use up a lot of energy. So, you will be able to save on energy bills that way.

However, there are certain drawbacks you should be aware of. This purifying and humidifying unit doesn’t have a timer or a humidistat. And while the air-washing with water can work, it can’t compete with an actual HEPA filter. Furthermore, it doesn’t do a great job when it comes to getting rid of odor from a room and won’t allow you to use essential oils in the mist.

Bottom Line

This unit requires little maintenance but also lacks features of other combos, such as a timer and humidistat. Also, this does not use filters to capture the pollutants. This unit is great for humidifying and does clean the air to an extent. It may be a great option for your needs.

Dreval D-950 Air Purifier and Humidifier Combo - H13 True HEPA Filter for Allergies, Pets, Dust, Mold, Pollen and Smoke - For Home, Office, or Bedroom


  • It is Easy to Control.
  • Offers Clean Air by Using the Seven-Stage Filtration Process
  • Sleep Mode Ensures This Unit is as Silent as Possible While Working


  • The Water Tank is Very Small

Our Review

The final recommendation on our list is the Dreval D-950. This model features quite a number of filtration systems to ensure the indoor air you breathe is of as high a quality as possible. There are a whopping seven stages of filtration in this one. This unit is for getting rid of bacteria, dust, allergens, pollen, and odor. It offers an area coverage of 430 square feet.

The seven stages of filtration in this unit are the cold catalyst filter, cellular activated carbon filter, antibacterial filter, HEPA filter, ultraviolet germicide light, anion purification, and ultrasonic humidifying.

These filters work together to get rid of dangerous gaseous substances, microbes, and other pollutants in the air. The UV light (from a 245nm wavelength UV lamp) kills germs and prevents the odor they might have otherwise caused. The ultrasonic humidifier can discharge a cooling sensation and keep humidity levels in check. It can help with offering some relief during coughs.

While the filtration process offered by this unit is impressive, the water tank is very small. This means that if you are in an environment with a lot of dry air, you will find yourself refilling this unit many times throughout the day.

The sleep mode ensures tranquil operation. You can easily put this combo unit in the nursery. It is also friendly to use, even for kids.

Bottom Line

The Dreval D-950 is all about making sure your household gets to breathe the cleanest air possible. The seven-stage filtration process is impressive. However, the small size of the water tank does make the refilling process annoying.
