One of the finest air purifier-humidifier combos on the market, this Sharp PlasmaCluster unit has a phenomenal set of features. It uses an ionizer and filters to improve the air quality while increasing humidity levels across the place.




Our Review

If you are looking for quality and performance in a single unit, this Sharp PlasmaCluster unit is the one for you.

The 3-stage air purification and humidification functionality make it essential in places with dry climates.

The pre-filter captures large solid particles like pollens and other allergens, while the HEPA filter ensures the removal of 99% of small solid particles like dust and mold from the air; thereby providing clean air to breathe in.

What makes this unit stand out is the Plasmacluster technology. The ionizer oxidizes unwanted particles, so the air becomes fresher.

Meanwhile, the activated carbon filter takes care of the odor and VOCs.

Both the pre-filter and activated carbon filter are washable, thereby adding value to your bucks. You will love how durable this unit is. While the activated carbon filter can easily last for up to five years, the HEPA filter needs to be replaced after 12-months.

You can turn on or off the humidifier feature as per your choice. Another interesting part of this model is the senor. Three sensors detect the air quality, temperature, and humidity levels and then adjust the fan speed accordingly to provide a comfortable environment.

This model is designed to cover up to 254 sq. ft of area, making it an excellent choice for bedrooms and small living rooms. Since the unit is not too heavy, you can easily move it around the house according to your needs.

If it wasn’t for the price, the Boneco H300 model combo would have topped our list of the best purifier and humidifier combos on the market.

With a high-end air-filtration system and impressive humidifying capacity, this unit meets all industry standards and therefore lives up to customers’ expectations.




Our Review

A pretty advanced unit, the Boneco H300 purifier and humidifier embodies high-quality features.

Firstly, this 3-in-1 hybrid model works as an air purifier, humidifier, as well as a combination of purifier and humidifier. This makes it a suitable choice for everyday use as per your requirements. You can use it to both improve the air quality and the relative humidity levels in your home.

This unit profiles the air by using a two-stage filtration system.

The first stage includes a washable pre-filter that works brilliantly to capture solid particles like pollens; dust particles, and pet dander. This feature makes it extremely suitable for use around people with respiratory conditions like asthma.

Next comes the pleated fibrous filter that efficiently traps 95% of airborne pollutants to purify the air. For humidity, the unit uses a rotating evaporative mat. The humidity level is maintained all the time, thanks to the large capacity water tank and the built-in hygrostat.

One of the most exciting features is the multiple profile sets that allow you to set the unit to: Auto, Sleep, or Baby modes. Similarly, you can set the unit at six different fan speed levels to suit your needs.

Last but not least, the Boneco H300 is extremely user-friendly. You can control it through an app on your smartphone while sitting in your chair.

Those looking for a great purifier and humidifier combo on a budget should definitely get their hands on this model from OPolar.

One of its kind, the OPolar EV01 has a fine construction with efficient filters to effectively remove dust; pollutants, and mineral deposits from the air while maintaining a comfortable humidity level.




Our Review

Get yourself a reliable purifier and humidifier combo at a very reasonable price with the OPolar EV01. The robust build is well-complemented by a sleek and trendy design, which gives your interior an elevated look. It is overall compact and lightweight, which enhances its portability to a great extent.

For air purification, the EV01 is incorporated with embedded filters. The amazing combination of reinforced nylon fiber and polyester in the filter construction makes them extremely durable. They trap and remove dust particles; air pollutants, and multiple allergens from the air, leaving behind fresh clean air.

Similarly, when it works as a humidifier, it can easily increase the humidity level up to 40%. The incorporation of 0.8-liter water gallon makes this humidifier a suitable choice for medium to small-sized rooms.

What we really like about this model is how convenient it is to use. The installation is a breeze and hardly takes time.

Additionally, there is no chance of water leakage, thanks to the physical evaporation that also keeps the humidity levels maintained. Since the grills are removable, you can easily refill the tank by pouring water in it like you would water a plant. 

There is a nice display panel to help you monitor the humidity levels. Lastly, the unit is not only energy-efficient, but it is also so silent that you won’t even realize it’s working.

The Venta LW25 humidifier and air purifier combo is an all-rounder with a silent operation and easy maintenance. From natural evaporation and excellent air purification to a practical design and a reliable warranty, this model covers everything.




Our Review

Made in Germany, there is no question about the durability of this Venta LW25 humidifier and air purifier. The design is both compact yet attractive to look at. It lets you achieve both purification and humidification with low energy requirements of only 8W.

It uses Airwasher technology to eliminate pollutants from the air. A stack containing multiple discs inside the water reservoir helps in the production of a cool mist.

The discs capture pollen; dust particles, pet dander, as well as pollen to keep the air fresh. This feature also makes this model one of those units that use water to remove unwanted particles from the air.

The best thing about the LW25 is that it does not require an expensive HEPA filter, which also means you don’t have to replace the filter after 6-12 months.

While the purifier is excellent, the humidifier also offers an unmatched performance by increasing the humidity levels up to 40%-60%. Thanks to the two-liter water capacity of the tank, you don’t have to refill the reservoir every few hours.

Another interesting feature is the sensor alerts you when the water level turns low. Similarly, the auto-shut-off feature automatically turns off the unit once there is no water left in the tank.

This unit has three fan settings, but it is pretty silent even at the highest level. Therefore, you can enjoy a sound sleep or continue working without facing any inconvenience.

The Oreck humidifier and air purifier combo caught our attention with its impeccable design. With a great set of filters and a built-in humidistat, this unit ensures an unforgettable experience every time you use it.




Our Review

The Oreck humidifier and air purifier combo has made its way to our list for its durability; versatility, and quality. It features a high-end construction coupled with a sleek and stylish design. You can easily place the slim frame in any room without it looking bulky.

This unit uses a 2-stage filtration system, thereby combining the effect of both charcoal and HEPA filters.

The HEPA filter traps 99% of airborne pollutants, including pet dander; allergens, smoke, and dust particles, while the charcoal filter is effective against bad odors. This makes the air fresh and clean to breathe in.

Moreover, the ultrasonic humidifier incorporated in this model releases a very cool mist along with purified air. The use of water instead of hot steam makes this unit extremely safe to use around kids.

Plus, due to the built-in humidistat, there is no need for a hygrometer to measure the humidity levels. The unit automatically senses the humidity level and adjusts the settings accordingly.

The Oreck model is also incorporated with a number of smart features that help you make the most of it. The water indicator level lets you know promptly when the level is low.

Similarly, the auto-shut-off feature automatically turns off the unit when the water tank gets empty.

Finally, a filter indicator on the display alerts you whenever you need to change the filter.

Air Purifier and Humidifier Combo: Buying Guide

What is an Air Purifier Humidifier Combo and How Does it Work?

2 in 1 air purifier and humidifier

As the name suggests, an air purifier humidifier combo is a combination of an air purifier and humidifier in a single machine. The unit is designed to purify the air while adding moisture to maintain good humidity levels.

The machine generally consists of a filtration system that removes all the contaminants from the air and a humidifier that uses a water tank to keep the air moist in dry places.

Why Buy an air Purifier Humidifier Combo Over Individual Machines?

Getting an air purifier humidifier combo is a smart investment. It effectively removes all impurities from the air while adding moisture to keep the environment nice and healthy.

Investing in two separate machines means additional cost and energy expenditures. Contrary to this, the combo machine incorporates the features of both an air purifier and humidifier in a single housing. This makes it a cheaper and space-efficient model as compared to two separate devices.

Additionally, a single unit is relatively easier to use and consumes less energy than individual units.

What to Look for in an Air Purifier-Humidifier Combo Machine

To make sure you get a unit that is perfect for air quality, humidity, and the size of your place, make sure you consider the following:

Capacity of the Tank

The capacity of the water reservoir varies from model to model. It ultimately depends on your needs and the size of the room. While smaller tanks are enough for smaller rooms and areas, you will need a large tank for a room where the unit will be running all the time.


Portability is important, especially if you intend to use the purifier and humidifier combo in different rooms or places. Go for a compact model so you can easily move it around to match your needs.

Area Coverage

Another important factor to consider is the area coverage of the humidifier and air purifier. A unit with area coverage less than the size of your room will not put out enough moisture. Likewise, the air won’t be as pure either.

Therefore, make sure to measure the size of your place and then look for a unit that has an area coverage the same or higher than those measurements.

Energy Efficiency

Energy efficiency works as the cherry on the top for a unit with stunning features. It is always suggested to go for an energy-efficient unit as it will help you cut down on your monthly bills in the long run. 


A user-friendly design helps you make the most of the unit. A clear display panel, smart features, easy refill, removable grills, and simple installation are just some features that facilitate ease of use.

Therefore, you should opt for a model that is not only brilliant in its performance but also easy to use whenever you want.

Operating Temperature

While an air purifier does not directly change the temperature, the outgoing air from the machine is cooler. Therefore, this drops the temperature of the room.

Before picking a particular model, make sure to check the temperature range. Low operating temperature will keep the unit from working in a place with a higher temperature.

Filter Life

The durability of filters adds value to your bucks. While it depends on the use, you need to change the filters after every several months. The best you can do is select filters made from premium materials that are sure to last you for some time.

Pros and Cons

Breathing in clean air is essential for improving your health and lifestyle. And while an air purifier-humidifier combo can help with that, such machines don’t come without their limitations. Have a look.


Contaminant-Free Air:

Pollutants in the air are harmful to your health. The air purification function of the machine eliminates this danger by removing all unwanted particles and impurities from the air. 

No Dry Air:

Dry air can lead to various issues like dry lips, sinuses, as well as a bloody nose. The combo unit also works as a humidifier and increases the humidity to a healthy level.

Space-Saving Option:

Not everybody has a large household where placing two separate appliances is not a big deal. A combo machine combines two units in a single case and takes the space of only one appliance. This makes it suitable for people with tight spaces and small houses.


Investing in a single machine saves you from purchasing two different appliances. Similarly, there will be reduced energy consumption, so you can save a significant amount monthly.

Higher humidity levels can ultimately lead to mold growth. This is extremely harmful to people suffering from allergies and asthma. The only way to avoid this problem is proper cleaning of the unit at regular intervals.

Cleaning and Maintenance

Investing in air-improving technology brings comfort. However, proper maintenance and cleaning are essential to upholding the efficacy of an air purifier-humidifier combo machine. Here is what you can do to keep the unit functional in the long run.

  • Make sure to clean the machine at least once a week.
  • Read the instruction manual carefully before using the unit.
  • Run the unit for a specified period in order to prevent overheating.
  • Always clean the water reservoir to limit mold growth.

As for cleaning, here’s what you need to do:

  • Use a damp sponge or a soft cloth to clean the exterior housing of the machine.
  • Use a soft on the disc stack to remove all the dirt.

Change and wash the filter at regular intervals.

Frequently Asked Questions

2 in 1 air purifier and humidifier

Can we use both the humidifier and air purifier together?

Of course, you can. Both units perform exclusive jobs. While an air purifier captures and removes airborne pollutants, a humidifier is responsible for adding moisture to the air and preventing it from getting dry. A combo model is better since it ensures energy efficiency.

Is the air purifier and humidifier combo machine energy-efficient?

Yes, it is. Running two different appliances will consume more electricity for separate jobs. Contrary to this, a purifier and humidifier combo draws energy for one appliance while handling two tasks at the same time.

Are air purifier and humidifier combo machine models just as good as the individual purifiers and humidifiers?

A combo machine is not as effective as an individual purifier and humidifier. While the machine is enough to serve the basic needs, you should get separate units for the best results. 

Final Verdict: Which is the Best Air Purifier Humidifier Combo and Why?

While all the models mentioned above are worth consideration, we find the Sharp PlasmaCluster Humidifier and air purifier the best for having outdone itself in terms of features, durability, and performance.

The three-stage filtration with HEPA filters ensures an unparalleled experience to the user, ensuring that only clean and fresh air with the right humidity is left behind.
