Air Purifier and Humidifier Combo

These days we spend most of our time indoors, but a common mistake we make is thinking indoor air is cleaner than outdoor air. In fact, indoor air contains higher levels of harmful chemicals, typically from household cleaners and air fresheners. Additionally, dry air can cause various health issues if not addressed properly.

Air purifiers consist of several filters to remove all kinds of particles that contaminate the air we breathe, while humidifiers emit extra moisture to combat dryness and its harmful effects. A combination of air purifier and humidifier in one device can play both functions while saving you space and money.

The best unit for you will depend on the size you need for your room, the different types of filters, and how long the humidifier can run. To learn more about the features you need to look for, check out our top five picks below.

Top 5 Air Purifier and Humidifier Combo

Sharp Triple Action Plasmacluster Air Purifier with Humidifier

Let’s start off our list with the Sharp Triple Action PlasmaCluster KC-850U Air Purifier with Humidifier. This unit utilizes a three-stage air purification with True HEPA Filtration and Plasmacluster Ion Technology to trap smoke, dust, pollen, pet dander, and other particulates. Furthermore, the ionizer function eliminates microscopic pollutants by producing positive and negative ions from water vapor in the air.

This Sharp Plasmacluster unit can cover up to 254 square feet, fit for small to medium size rooms. The built-in temperature, dust, and humidity sensors monitor your air quality to automatically clean and humidify your room as needed. You have the dust particles and relative humidity monitors on the front display panel. 

The humidity sensor automatically adjusts humidity according to the current room temperature. In Clean Air and Humidify mode, it produces 23 decibels on low settings, making it ideal for bedrooms and small living areas. Additionally, you can dim the lights or turn them off completely for a peaceful sleep.

The three-stage filtration includes a washable pre-filter that traps dust and other large airborne particles, an activated carbon filter that removes odors, and a True HEPA filter that effectively eliminates 99.97% of particles as small as 0.3 micron from the air.

The humidifying wick filter can be washed and reused for up to two years.

If you need a bigger unit, consider the Sharp KC-860U for rooms up to 341 square feet. However, a few issues worth noting are the small tank and ineffective humidification of the Plasmacluster air purifiers. Also, this product comes with only one year of warranty on parts and labor.

What is an Air Purifier Humidifier Combo

Firstly, let’s talk about what an air purifier does for you. Air purifiers work to reduce pollutants and allergens in the air, including dust particles, smoke, pollen, pet dander, and mold spores. They clean the air using different types of filters that catch these impurities. An air purifier can enhance indoor air quality, effectively minimizing allergies, asthma attacks and other respiratory problems. However, it does not control humidity or release moisture.

On the other hand, humidifiers can help reduce allergy symptoms and skin irritation when the air is too dry. Humidifiers work by adding moisture to the air. They are commonly used during the winter season when the air is cold and dry. One type of humidifier is called evaporative. It uses a wick filter to absorb water from the unit’s reservoir. A fan then blows through the filter, letting the moisture evaporate. Another type called an ultrasonic humidifier produces mist using a high-frequency vibrating metal diaphragm instead of a fan. 

An air purifier humidifier combo product saves space and electricity because it can both humidify and purify the air at the same time from a single device. The air purifier part will first filter the air drawn into the unit. Then, the humidifier will add moisture to the purified air before releasing it to the room. While you can buy an air purifier and a humidifier separately, it’s perfectly reasonable to use a 2-in-1 device to save money and space.

Benefits of Using an Air Purifier and Humidifier Combo

According to the EPA, indoor air is actually two to five times more polluted than the outdoors. This can be attributed to the higher concentration of volatile organic compounds (VOCs) found in household materials such as cleaning supplies and personal care products.

Other common pollutants in your home include harmful gases such as carbon monoxide (from gasoline or fuel) and formaldehyde (from building materials). When indoor humidity is left unchecked it can also make your home a breeding ground for some allergy triggers such as dust mites and mold. An air purifier can help improve the air quality in your home by filtering out tiny particles. 

Meanwhile, during dry and cold seasons, you may be dealing with uncomfortable breathing, nosebleeds, and more serious respiratory issues. Cold and dry air also contributes to the spread of upper respiratory viruses. A humidifier helps relieve your nasal passages, hydrate your skin, and alleviate symptoms of other common winter ailments.

You can get all these benefits in a single device when you use an air purifier humidifier combo.

Finding the Best Air Purifier and Humidifier Combo

When choosing an air purifier humidifier combo, you need to consider a few important factors to ensure that both functions are working as needed.


To find the best unit for you, the total area of your room is a critical factor to consider. The coverage refers to the square footage of space the unit is able to purify and humidify. Depending on the clean air delivery and humidification rates, your air purifier humidifier should have a recommended area of coverage. Remember to choose just the right size for your room. Using a smaller unit than you need may not have a significant impact on the air quality and humidity of your room. While a bigger unit may emit too much moisture, causing different problems for you.


When talking about air purifiers, the type of filters is another important consideration to make. All filters catch impurities from the air up to a certain amount, but some may be more effective than others. Most air purifiers include more than one filter for a more thorough purification. A pre-filter will capture large particles like dust and lint while the HEPA (high efficiency particulate air) filter catches tiny particles. 

In addition, an activated carbon filter eliminates unpleasant odors to keep the air smelling fresh. These filters are washable and reusable up to a specified period depending on your indoor air quality and frequency of usage. You may want to look for a unit with filters that last longer so you can save on maintenance costs.

Run time

The run time of your humidifier depends mainly on the tank capacity, size of your room, and discharge rate. Features like the auto stuff and timing functions are also helpful so you can leave your unit running while you sleep or when you’re away.


Can I use both an air purifier and humidifier together? 

Yes. An air purifier and humidifier perform two completely different functions and they can be used together in the same room, improving indoor air quality and humidity at the same time.

Does a humidifier clean the air? 

No. A humidifier does not directly affect the air quality. It simply releases water vapor or steam to increase humidity levels.

Do air purifiers cool the air?

No. An air purifier does not cool the air, although it uses a fan to circulate the air through its filters.
