“I’m looking to buy an air purifier and humidifier. Which ones would you recommend?”
This is the typical air purifier and humidifier combo request we get. EPA stated that indoor air can be 2 to 5 times more contaminated than outdoor air. Opening windows during a heating season doesn’t make a lot of sense.
On the other hand, during the winter heating season, we all struggle with low indoor humidity levels. If you ever woke up with dry eyes, dried skin, and dry mouth, you know how dry 20%-30% relative humidity feels.
In HVAC, we have two devices that can solve this:
- Air purifiers to increase indoor air quality.
- Humidifiers that can increase relative humidity levels to a comfortable 40% – 60%.
The effect of both combined is clean non-dry air:
You could buy both an air purifier and a humidifier. However, the perfect solution would be a 2-in-1 air humidifier combo. Fortunately, these combos do exist, but there are not a whole lot of them.
The advantages of a humidifier and air purifier in one are quite apparent; you can get 1 device with 2 functions. You don’t have to buy 2 devices, have double wires, pay double electricity costs, and so on.
To address the frequent request of “which is the best air purifier and humidifier combo”, LM has created a list of the top-rated 2-in-1 air purifier humidifier combos.
The goal here is to have a device that is:
- As good as an air purifier as a designated air purifier. To capture dust, smoke, pollen, mold, and so on and increase the quality of the air we breathe.
- As good a humidifier as a designated humidifier. To get rid of dry indoor air by elevating relative humidity rates to an optimal 40% – 60%.
Here’s the deal:
Most air purifier and humidifier combos are either purifier-heavy or humidifier-heavy. Specifically, the best 2-in-1 combo is the Sharp Plasmacluster KC-850UH precisely because it’s the perfect balance between air purification and humidification function.
Below you will find a comparison table of the best 6 air purifier humidifier combos, followed by reviews of each unit. Here is the list of best 2-in-1 humidifier and air purifiers to start with:
- Sharp Plasmacluster KC-850UH (Best Air Purifier And Humidifier Combo)
- Miro Pro 2-In-1 (Top-Rated Air Purifier Humidifier Combo By Afloia)
- Venta LW25 Airwasher (Best Large Room Air Purifier Humidifier With 2-Gallon Water Tank)
- Dyson Pure Humidify+ PH01 (Premium Advanced Air Purifier And Humidifier)

1. Sharp Plasmacluster KC-850UH Review (Best Air Purifier And Humidifier Combo)
|Coverage Area:||254 sq ft (5 ACH)|
|CADR Rating:||164 Smoke / 164 Dust / 174 Pollen|
|Filters:||HEPA Filter + Deodorizing Filter + Humidify Filter|
|Dimensions:||14.9 x 10.5 x 23.1 inches|
Sharp Plasmacluster KC-850UH is the perfect combination of an air purifier and humidifier. While most air purifier humidifier combos can be humidifier-heavy, the Sharp Plasmacluster KC-850UH found the perfect balance between improving indoor air quality and increasing relative humidity levels.
Air Purifier Function
Sharp Plasmacluster KC-850UH has a 4-stage filtration system. The first 3 stages are on par with most classic air purifiers like Alen, Coway, Blueair, Levoit, Okaysou, and so on. Here’s the 3-stage filter setting:
- Pre-filter traps larger solid particles, like pet dander, thereby protecting the fine HEPA filter.
- Activated carbon filter adsorbs gaseous air pollutants, like cigarette smell and unpleasant cooking odors.
- HEPA filter captures small solid particles; more than 99.97% of the smallest 0.3 microns in diameter dust particles, pollen, mold, allergens, and so on.
What really elevates the Sharp Plasmacluster KC-850UH’s air purification function is the plasma cluster Ion Technology filter. This 4th filter is tested via 17 USA, UK, Germany testing procedures to reduce certain viruses, bacteria, and mold. These include MS2 virus, E-Coli, Staphylococcus, Epidermidis bacteria as well as Penicillium and Aspergillus Niger mold.
Sharp Plasmacluster KC-850UH comes with a humidification filter. This is a washable filter with a 5-year lifespan. More important than that is its function; it’s this filter that makes the Sharp Plasmacluster KC-850UH an air purifier dehumidifier combo.
The humidification filter works together with the 0.96-gallon water reservoir to increase indoor humidity levels. In the winter, the heating can drop the humidity levels below 20%. Sharp Plasmacluster KC-850UH’s humidification filter continually moisturized indoor air and lifts it higher, to that ideal 40% relative humidity levels.
All in all, the Sharp Plasmacluster KC-850UH is a perfect marriage of air purifier and dehumidifier 2-in-1. You can put in pretty much any room where you want to remove air pollutants and increase humidity levels simultaneously:
2. Miro Pro 2-In-1 (Top-Rated Air Purifier Humidifier Combo By Afloia)
|Coverage Area:||270 sq ft (2 ACH)|
|Filters:||HEPA Filter + Prefilter + Activated Carbon Filter|
|Dimensions:||7.67 x 7.67 x 21.77 inches|
Miro Pro 2-in-1 is one of the first true air purifier humidifier combos. As you know, the basis for every air purifier is a HEPA filter. Sadly, most of these air purifier and humidifier combo units don’t really have a HEPA filter. Miro Pro 2-in-1 has one that can capture more than 99.7% of airborne particulates that are 0.3 micrometers in diameter.
This is a smaller combo unit. Thanks to the inclusion of the HEPA filter, it can achieve a CADR rating of 89 CFM. This is enough to be used in rooms up to 270 sq ft if you want 2 ACH. The coverage at 5 ACH is much smaller; down to 108 sq ft.
In addition to the HEPA filter, the Miro Pro 2-in-1 also includes:
- A prefilter. This is a filter that captures all the larger particulates like hair and pet dander (all the fluff). It also protects the vital HEPA filter.
- An activated carbon filter. This filter adsorbs smell-causing odors. These odors in gaseous form are caught by the carbon filter. That means that the Miro Pro 2-in-1 can also eliminate undesired smells in your home.
Humidifier-wise, the Miro Pro has a bit smaller water tank (0.5 gallon, to be exact) than comparable combo units. That means that you will have to fill it up with water more frequently. The humidifier is positioned on the top of Miro Pro; it can be detached if you want to use just the air purifier without the humidifier.
Miro Pro is quite a popular air purifier humidifier because it’s not big and bulky like most of the other units. It’s slim and has a visually appealing design. With quite a low price (below $150), it is also one of the most affordable combos for air purification and humidification you will likely find:
3. Venta LW25 Airwasher Review (Best Large Room Air Purifier Humidifier With 2-Gallon Water Tank)
|Coverage Area:||400 sq ft|
|Filters:||Air Washer (No Filters)|
|Dimensions:||11.8 x 11.8 x 13 inches|
Of all the air purifier humidifier combos, the Venta LW25 Airwasher has the best humidification function. The centerpiece of the all Venta combos, including the LW25, is the airwasher.
Airwasher helps to achieve both humidification and air purification. It consists of a disc stack which rotates inside the water reservoir. The water washes the air pollutants such as pollen, dust, smoke particles, as well as mold, and pet dander away. Hence Venta LW25 Airwasher is one of the very few humidifier air purifier combos that use only water to remove air pollutants.
The best part of this principle is that you don’t need filters as with other air purifiers. Most will employ HEPA-filtration based system; these filters need to be replaced every 3-12 months, and that’s quite bothersome. In the case of Venta LW25 Airwasher, the airwasher disc does all that using water instead of HEPA filters.
Venta LW25 Airwasher has the best humidifier function. With its large 2-gallon water tank, you can reach the optimal 40% – 60% levels with ease, even during the heating season.
Venta LW25 Airwasher is designed to humidity as well as work as an air purifier in about 400 sq ft spaces. On top of that, it has low noise levels (below 44 dB) as well as low energy-requirements (max. wattage is 8W).
All in all, this is primarily humidification but it will simultaneously work as an air purifier combo as well.
4. Dyson Pure Humidify+Cool PH01 Review (Premium Advanced Air Purifier And Humidifier)
|Coverage Area:||Large Room|
|Filters:||360 Glass HEPA Filter|
|Dimensions:||12.3 x 12.3 x 36.4 inches|
Dyson Pure Humidify+Cool PH01 is the latest device from Dyson. Dyson is a big company that makes pretty much anything that requires a fan. Air purifiers (you can check Dyson air purifier reviews here) are just one such example.
In the latest PH01 model, Dyson decided to marry an air purifier with a humidifier. Dyson Pure Humidify+Cool PH01 is the result: in addition to simultaneously function as a humidifier and air purifier, it can also work as a cooling fan in the summer.
As such, the PH01 is the perfect all-season air purifier. In the winter, we all struggle with low humidity levels (results of heating). The PH01’s humidifier can increase relative humidity while it’s air purification function with a 360-degree HEPA filter, pre-filter, and activated carbon filter captures large and small particles as well as undesirable odors.
In the summer, we struggle with the heat. Dyson Pure Humidify+Cool PH01 works as a cooling fan; perfect to create a refreshing breeze while also increasing indoor air quality via air purification function.
This Dyson air purifier humidifier combo has a 1-gallon tank and can be used both in mid-sized as well as larger rooms, like bedrooms, living rooms, or even in the kitchen.
All in all, the Dyson PH01 is a brilliant air purifier and humidifier combo. But, like all brilliant devices from Dyson, it has a higher price tag. Nonetheless, if you’re looking for a high-quality device that can increase both air quality as well as air humidity, the Dyson Pure Humidify+Cool PH01 is well worth the cost:
5. OPOLAR EV01 Review (Cheapest Air Purifier And Humidifier Combo)
|Coverage Area:||108 sq ft (5 ACH)|
|Dimensions:||13.7 x 14.9 x 7.6 inches|
OPOLAR EV01 is a small room air purifier humidifier combo. It’s primarily a humidifier, designed to increase indoor relative humidity levels above 40% in the winter. The best part is that this humidifier is complemented with a superb air purifier function.
It has a smaller 0.8-gallon water tank that actually quite large for a 108 sq ft recommended coverage area purifier humidifier combo. OPOLAR EV01 can use that 0.8-gallon water tank to humidity indoor air for about 24h, depending on the initial relative humidity levels. That simply means that you can easily run this humidifier air purifier during the night and it won’t need to be refilled at least until morning.
In addition to the humidifier function, POLAR EV01 works as an air purifier as well. It has a honeycomb construction with embedded filters. These eliminate dust, mineral deposits, and other air pollutants. The filter is made out of reinforced nylon fibers and polyester. This makes it durable but it’s not as effective as the HEPA filter we see in Dyson PH01, for example.
OPOLAR EV01 is silent and energy-efficient. The two drawbacks are that it’s often too small for a larger bedroom and that, despite superb humidification function, the air purification function is somewhat lacking.
The best part of the OPOLAR EV01, however, is the very low price. This is the only small room air purifier and humidifier combo available for less than $100.
6. BONECO H300 Review (Still Good Air Purifier Humidifier For Small Rooms)
|Coverage Area:||108 sq ft (5 ACH)|
|Filters:||HEPA Filter + Air Washer|
|Dimensions:||14 x 12 x 21 inches|
BONECO H300 is a 3-in-1 hybrid. It can work as either humidifier, air purifier, or a combination of air purifier and humidifier. For small rooms, it represents a perfect way to forgo buying both an air purifier and dehumidifier; you can just use the BONECO H300 to both elevate indoor air quality as well as increase relative humidity levels.
For a combo of an air purifier and humidifier, the BONECO H300 is quite advanced. It has 6 performance levels, including the Auto Mode, which you see in the best air purifiers by Coway, Molekule, and Blueair. On top of that, the BONECO H300 can be wirelessly connected to a smartphone. It’s the only top-rated air purifier humidifier combo that can be controlled via a smartphone app.
It’s humidifier-heavy; with a 1.85-gallon water tank. That’s quite a big water tank, enough to increase humidity in the medium-sized rooms as well as in small rooms.
The air purification function, however, is not that brilliant. BONECO H300 can achieve a CADR rating of 53. It doesn’t use a HEPA-based filtration system. Rather, it relies on airwasher system whereby air pollutants are captured and washed into a tank by water instead of filters.
BONECO H300, in essence, is a combination of a superb medium-size room humidifier and a weaker small room air purifier. It has quite decent specs. However, the price is on par with the Sharp Plasmacluster KC-850UH, and if you have to choose between the two, the choice is quite clearly in favor of Sharp Plasmacluster KC-850UH.
Air Purifier Combined With Humidifier FAQ
LM answers the most common questions when it comes to a combo of air purifier and humidifier:
Can You Use An Air Purifier And Humidifier Together?
Humidifier uses water to increase indoor humidity levels and prevents air from being and feeling dry.
Of course, it’s best to use a 2-in-1 air purifier and humidifier combo because that’s one device instead of two.
Is Air Purifier Better Than Humidifier?
Depends on your situation. If you have low indoor air quality, an air purifier is better than a humidifier. If, on the other hand, you suffer from air dryness, using a humidifier makes more sense.
During the winter heating season, you usually need both an air purifier and a humidifier.
Do Humidifiers Filter Air?
No, humidifiers are not designed to filter air. They increase indoor relative humidity.
Air purifiers are HVAC devices that filter air and capture air pollutants.
