According to the CDC, the average American spends 90% of their time indoors where the average number of air contaminants can be 2-5 times higher than outside. A dry environment caused by a lack of humidity can also cause a number of negative effects on your health from dry throats to more major issues involving viruses like Covid-19.

Previously you need to purchase two appliances, an air purifier to deal with cleaning the air of pollutants and a humidifier to increase the level of humidity.

As of 2022, there is now a new gadget available, the air purifier and humidifier combo which can clean air and humidify the air all in one unit.

How Did We Choose the Best Air Purifier and Humidifier Combos to Recommend?

The best purifiers contain true HEPA filters and activated charcoal as these are filter technologies that have been shown again and again in peer-reviewed papers to be effective at cleaning the air. These capture the greatest number of harmful airborne particles, reducing the growth of bacteria and the spread of toxins. And while there are different types of humidifiers on the market, an evaporative unit is most effective when used in conjunction with a purifier.

When picking out our top choices, we also looked at special features like:

  • Low noise levels
  • Easily refillable
  • Touchscreen controls
  • Wireless technology

As with any home appliance you will also need to consider:

  • Your budget
  • The size of your room (large filters are needed for larger rooms)
  • The type of filters it uses and long term electricity costs
  • How much your home is affected by humidity and pollutants

Finding the right unit to fit your specifications can be overwhelming. Our list is compiled of air purifier and humidifier combos for a variety of needs, budgets, and different sizes of rooms. We evaluated data from Consumer Reports (USA), Which (UK) as well as using manufacture data and consumer analysis to choose what we think are the very best air purifier and humidifier combos.

1. Dyson Pure PH03

Dyson is a big name in household cleaning products. They revolutionized the vacuum cleaner and have recently stepped into the air purification and humidifier game. The PH03 is their third offering in their purifier-humidifier combo range and is the best combination unit on the market but it doesn’t come cheap. In true Dyson style, they have gone for a modernistic approach to design and functionality and a large price tag!

Dyson also has a PH04 that is a similar unit but with special filters for dealing with formaldehyde for an extra $100.

This 3-in-1 unit also features a fan to project the fresh, moist air backward and forwards with up to 90-degree oscillation for maximum airflow. It has smart sensors that will monitor air quality, temperature, and humidity levels, sending the information to the Dyson link app on your smartphone. 

Be sure to also check out our review of the Dyson HP04 as it’s this unit but with a heater as instead of a humidifier.

The Dyson Pure PH03 Specifications

  • It uses a combination of activated carbon and HEPA filter for purification
  • Has a deep clean function to avoid bacteria and mineral buildup in the water tank
  • It will provide enough water in the tank for 36 hours of hygienic humudification without refilling.
  • The filter has a life of 4382 hours (6 months) after which will need changing
  • On its highest setting, the PH03 can reach 55dB
  • It has a 1-gallon tank capacity for humidification 

What We Really Like:

👍 It can be voice-controlled using Amazon Alexa and Apple Siri

What We Think Could Be Better:

👎 The filters cost around $80 every 6 months
👎 $900 for one unit is a lot to ask for air purifier performance that you can get with a far cheaper unit.

2. Sharp KC-850U

The KC-850U is the flagship of Sharp’s purifier-humidifier combo line and falls under the mid-range category. It has a bright display on the front which will inform you of the quality of the air, the humidity, and the remaining water level. On top is the control panel where every button is clearly labeled and accompanied by an LED.

The KC-850U can be easily moved between rooms weighing 21.4 lbs (without a full water tank). As well as the filters, it has what Sharp calls a Plasmacluster. This is a kind of ionizer that pulls apart airborne pollutants. Used in the right-sized room, this unit performs great as both a purifier and a humidifier.  

Sharp KC-850U Specifications

  • It uses an activated carbon filter to reduce odors, a True HEPA filter for small particles, as well as the Plasmacluster
  • Works best in rooms up to 254 sq. ft
  • Sharp claim that the filters will last up to 5 years
  • It can be as quiet as 19 dB on low speeds and as high as 60 dB when both purifier and humidifier are running on full
  • Running both features, 8 hours a day, will cost around $30 a year
  • The humidity tank holds 1 gallon of water

What We Really Like:

👍 It has smart sensors that detect and react to unhealthy air conditions

3. BONECO H300 Hybrid Humidifier & Air Purifier

This Swiss made device is a great choice for those looking for a mid-range air purifier-humidifier combo with a few great features. When it says “3-in-1” it means it can be used as a humidifier, purifier, or both. Weighing only 12.1 lbs when it’s empty means you can easily move it between rooms.

You’ll notice that there’s no actual interface on the H300. Everything is controlled by an app on your smartphone which connects using Bluetooth. The simplistic app will let you change between modes, adjust fan speed, and set the timer. There is a semi-circle of lights on the front panel so you can easily see which function the unit is currently running on. If fragrance is on your list of needs, the H300 comes with a tray for essential oils.

BONECO H300 Specifications

  • The unit comes with a filter that is designed to help with pollen allergies. If this doesn’t suit you, there’s a higher spec “comfort” filter available
  • It’s designed for rooms up to 540 sq. ft

👎 Doesn’t look as nice as others

4. Brondell Revive

The Revive from Brondell isn’t trying to disguise itself as anything other than a solid purifier-humidifier combo. Its control panel sits on top so you can easily change fan speed, modes, and engage the timer. It will also indicate the current humidity level between 3 categories, dry, comfort, and humid.

There are no fancy soundscapes or scented fusions, but the Revive does come with a dual True HEPA filter to take in twice the amount of air combined with an activated carbon filter to help get rid of any nasty odors as well as VOCs (Volatile Organic Compounds). The Revive prides itself on evenly distributing humidity so there’s no concentration around the unit which can cause damage to furniture.

Brondell Revive Specifications

  • It utilizes 3 filters, a dual True HEPA, active carbon filter, and a humidifier filter
  • If you need it to help with allergies we’d suggest using it in an area up to 376 sq. ft, for regular use, a room up to 627.5 sq. ft
  • Brondell suggest a filter change every 12 months
  • This unit can get up to 64 dB on its highest speed which is the loudest of the 7

Frequently Asked Questions About Air Purifier + Humidifier Combos

🤔 What do air purifiers do? What do humidifiers do?

Air purifiers use a powered fan to pull the air in from your room, remove pollutants through a series of filters, and replace it with clean air. The most effective air purifiers will contain a True HEPA filter which can trap pollutants as small as 0.3 microns. A humidifier’s job is to increase moisture to dry air in the home. Low humidity can be damaging to your health, causing dry skin, throat, lips, and can also cause shrinking and even cracking to wooden furniture. 

🤔 Can you use a humidifier and air purifier at the same time?

There’s nothing to stop you from using both devices at the same time. It’s recommended that you use both in the same room as they’re both doing different jobs. As you’re here, you’re most likely looking to get both jobs done with the same device which will save you both money and floor space.

🤔 What are the functions of a humidifier compared to an air purifier?

A humidifier is designed to add moisture to the air. They are designed so that they can offer warm moisture or cool moisture. When you look at an air purifier, this device is designed to purify the air. It doesn’t release any moisture in the air. Instead, it pulls in air, removing various airborne pollutants depending on the filters inside, and releases cleaner air back out.

Both a humidifier and an air purifier can make the air easier and healthier to breathe, however. Humidifiers work to provide more humidity to the air, which can help render virus particles ineffective, making them useful during cold and flu seasons. Air purifiers remove pollen, dust, and even some airborne bacteria and viruses.

🤔 Does a humidifier help purify the air?

No, a humidifier on its own can’t exactly purify the air. It’s built to add moisture to the air to raise humidity levels. That doesn’t mean it can’t help though. A humidifier can still make the air around you more comfortable, especially if you are sick or suffering from allergies. Moisture can help clear out congestion, making it easier to breathe through your nose as well as helping your coughs become more productive. If you want to completely purify the air from airborne particles, however, then it’s best to get an air purifier instead of just using a humidifier.

🤔 What is a True HEPA Filter?

HEPA stands for High-Efficiency Particulate Arresting. A True HEPA filter is made up of thin glass fibers which have a 99.97% efficiency rate at capturing small airborne particles. They have become industry standard in air purification, even NASA has studied this type of filter and concluded them to be the best way to clean the air in the home.

🤔 Do humidifiers clean the air?

No. Humidifiers change the amount of moisture in the air. They typically don’t contain the filters needed to clean the air (True HEPA filter) as air purifiers have.

🤔 Do air purifiers work better with a humidifier?

Since both air purifiers and humidifiers can improve indoor air quality, it makes sense that many would want to use the two together. This way, you can reap the benefits of them both with the air purifier eliminating common airborne ailments like allergens and the humidifier adding needed moisture to an otherwise overly dry room.

You can have an air purifier running alongside a humidifier, but you want to take care of the type you choose. Only an evaporative humidifier should run in the same room as an air purifier. This is because the visible mist humidifiers release dense mist that can cause some harm to the filters inside air purifiers. Combination units skip this problem by providing a unit that works seamlessly and incorporates features from both air purifiers and humidifiers.

🤔 So… Which air purifier humidifier combo is best for you?

Using an air purifier-humidifier combo can make a drastic difference to the quality of the air you breathe in your home every day. The trick is to find the right unit to suit your needs. Make the device work for you. There’s no point spending a whole load of dollars on a large or high-tech unit when all you needed was a small one with minimal features and you don’t want to skimp out on a budget unit that won’t work as well for your massive room.
