Having clean, healthy air to breathe is essential to creating a happy home. Unfortunately, clean air is hard to come by these days because it’s constantly plagued by pollutants such as dust mites, mold, pollen, volatile organic compounds (VOCs), and smoke. These pollutants are often responsible for your allergies, asthma attacks, and sinus problems. Alongside air pollution, dealing with low humidity levels is also one of the perils of modern living. Having dry air at home can cause nosebleeds, chapped lips, dry skin, and even cracked furniture, so it’s important to try and combat this

Normally, you’d need to have at least 2 devices to deal with all these problems: an air purifier and a humidifier. Luckily, air purifier-humidifier combos are appliances that purify and humidify the air at the same time. In this article, we’ll walk you through the benefits and features of the best air purifier-humidifier combos available on the market today, along with some helpful tips to help you choose the right model

1. Sharp KC-860U Plasmacluster

The KC-860U is a heavy duty air purifier that can easily take care of pollen, pet dander, mold, dust mites, and even light odors around your home. On Auto Mode, it will automatically adjust the fan speed depending on the air quality in the room. Similarly, when the humidistat detects low humidity levels, it signals the KC-860U to increase moisture output.

Aside from these amazing tricks, the KC-860U is quiet, energy efficient, and its humidifier doesn’t produce white dust. It also makes use of long-life filters that only need to be replaced every 5 years. The wick filter is washable and will last 2 years, depending on how often you use the humidifier which will save you money in the long run.

On the down-side, the KC-860U is the most expensive air purifier-humidifier on this list. In addition to the hefty price tag, the KC-860U’s water tank can only hold 1.14 gallons of water – so don’t expect it to be able to humidify the room for long periods of time.

Pros

  • Medium room coverage
  • Adjusts fan speed depending on air quality
  • Adjusts mist output depending on humidity level
  • Long life filters
  • Quiet
  • Energy efficient
  • No white dust
  • Great for removing different types of air pollutants
  • Several useful features

Cons

  • Expensive
  • Small tank
  • Large and bulky
  • No automatic shut off
  • Short warranty

The LW25 works by drawing air over a set of slowly rotating disks where air pollutants such as pollen and dust are effectively trapped. The water cleans the disks, leaves the air pollutants behind, and comes out as a clean, cool mist. It is quiet on all three output levels and humidifies quickly. What’s really great about the LW25 is that it’s very low maintenance for a humidifier, only needing to be cleaned every few weeks. With the help of its large, 2-gallon tank, the LW25 can cover large areas up to 400 sq. ft. in size, which is no small feat especially considering how compact it is.

Its high price, however, is only justifiable if you’re willing to pay more upfront for lower power consumption and infrequent refills and cleanings. Considering the hefty price tag, it is surprising that the Venta LW25 doesn’t come with more useful features such as humidistat or a timer. Moreover, as far as its “air washing” capabilities are concerned, you’d be better off with an actual HEPA air purifier which is able to remove air pollutants more quickly and efficiently.

In a nutshell, the LW25 is one of the best humidifiers out there, but you can’t count on it to be as efficient as an air purifier for removing air pollutants. If light air cleaning and heavy duty humidification are what you need, though, then the LW25 would be your best bet.

Pros

  • Low maintenance
  • Large room coverage
  • Large tank
  • Quiet
  • No filters to replace
  • Energy efficient
  • No white dust
  • Humidifies quickly
  • Small, compact
  • Long warranty

Cons

  • Expensive
  • Not as effective at removing air pollutants
  • Fewer features
  • No humidistat

The Boneco Air Washer W200 is a 2-in-1 air purifier-humidifier combo that comes in a compact size. With its 1.18-gallon tank, it is able to humidify and purify the air in spaces up to 540 sq. ft. in size. Using cool mist, it effectively removes common household air pollutants such as dust, pollen, and particle-bound odors.

The W200 is easy to clean and maintain, with parts that are dishwasher-safe. It performs extremely well and can reach the right humidity levels in a matter of minutes without making too much noise.

The main disadvantage to the W200 is that it won’t be able to remove smaller particles, smoke, odors, and VOCs as effectively as an air purifier would. For a mid-priced product, it also has a lot less features than the others in this list and a relatively small water tank that needs more frequent filling. For a mid-priced product, one might expect more features and a larger water tank – but all things considered; the W200 is an excellent alternative to the LW25 providing the same heavy-duty humidification and moderate air purification for a more affordable price.

Pros

  • Large room coverage
  • Low maintenance
  • Easy to clean
  • No filters to replace
  • No white dust
  • Humidifies quickly
  • Compatible with essential oils
  • Quiet
  • Sleek design
  • Energy efficient
  • Long warranty

Cons

  • Small tank
  • Not as effective at removing air pollutants
  • Fewer features
  • No humidistat

The Air Refresh WK15500B from Oreck is a tower-type air purifier with a built-in cool mist ultrasonic humidifier that is best suited for use in small rooms up to 115 sq. ft. in size . It makes use of a carbon filter and a HEPA-type filter to trap 99% of allergens, dust, and odors.

Convenient and easy to use, the WK15500B comes with a humidistat and is able to adjust the mist output depending on the humidity level in the room, and comes with a plethora of other useful features. It is, however, an extravagant purchase considering that it is only designed for small rooms, and doesn’t use a True HEPA filter.

Maintenance could also pose an issue – as the WK15500Bs filters need to be changed often, and the base of the unit needs to be drained of excess water after each use. These issues aside, the WK15500B is highly effective at trapping the bevy of air pollutants in your smaller space as well as providing just the right amount of humidity when you need it.

Pros

  • Adjusts mist output depending on humidity level
  • Sleek tower design
  • Several useful features
  • Quiet
  • Great for removing different types of air pollutants

Cons

  • Expensive (upfront and long-term)
  • Not a True HEPA filter
  • Small room coverage
  • Small tank
  • High maintenance
  • Difficult to drain

The Dreval D-950 is a console air purifier capable of scrubbing the air in areas up to 430 sq. ft. in size. It uses a comprehensive 7-stage air purification system consisting of a cold catalyst filter, carbon filter, antimicrobial filter, True HEPA filter, UV light treatment, an ionizer, and an ultrasonic humidifier. Consequently, the D-950 has the most comprehensive air purification system of all units on this list – making use of several technologies to ensure air pollutants are eradicated from your home. It also has a built-in cool mist ultrasonic humidifier that effectively adds moisture to dry air as needed.

You can also tell that the D-950 aims for convenience and ease of use with its remote control and included smart features. Both the air purifier and humidifier can be fully automated and will adjust their speeds depending on initial air quality. But unfortunately, with so many functions the D-950 isn’t as user-friendly as we’d like and had us going back to read the user manual several times. It is also high maintenance with different filters that need to be replaced regularly – and does not perform as well as a humidifier as it does an air purifier. Overall, though, what the D-950 lacks in humidifying power, it certainly makes up for in air purification. With its 7-stage air purification system, you can rest assured that the air is squeaky clean and safe for the whole family.

Pros

  • Large room coverage
  • Adjusts fan speed depending on air quality
  • Adjusts mist output depending on humidity level
  • Comprehensive air purification system
  • Good for a variety of air pollutants
  • Remote control
  • Several useful features

Cons

  • Expensive
  • Large and bulky
  • Bright LED lights
  • Difficult to use
  • Small tank
  • High maintenance
  • Difficult to clean

Air Purifier – Humidifier Combo Buyer’s Guide


What is an air purifier-humidifier combo?

An air purifier-humidifier combo is a device that is able to both purify and humidify the air. It may come in the form of an air purifier with a built-in humidifier or it may be a humidifier marketed as an “air washer” which is able to purify the air using water as a natural filter.

What is the difference between an air purifier and an air washer?

An air purifier is a device that is capable of removing air pollutants such as dust, pollen,, mold, smoke, VOCs, bacteria, and viruses by utilizing mechanical filters (e.g.: HEPA and carbon) or electrical filters (ionizer and UV). Some air purifiers come with a built-in humidifier as an added bonus to freshen the air even more. Generally, air purifiers that come with a humidifier use evaporative or ultrasonic cool mist technology. Unfortunately, since the humidifier is just an added feature, you can’t expect these air purifiers to have a large water tank or do a particularly good job of humidifying the air as compared to an actual humidifier.

Air washers, on the other hand, are humidifiers that are marketed as air purifiers as well. Manufacturers claim that these air washers are able to remove 99% of microscopic airborne pollutants only using water as a natural filter while at the same time effectively raising humidity levels in the room. Evaporative cool mist humidifiers are often used as air washers because pollutants are left inside the humidifier as the water evaporates. Unfortunately, studies have shown that air washers don’t actually do a particularly good job of “washing” the air. A mid-range HEPA air purifier is still able to outperform a high-end air washer by significantly reducing particle concentrations faster.

Who would benefit from an air purifier-humidifier combo?

An air purifier is highly beneficial for people who suffer from allergies, asthma, or other respiratory problems because it can remove the triggers that cause or worsen these conditions. In contrast, humidifiers are able to provide relief for people who suffer from sinus congestion, frequent cough, colds, and flu, as well as dry hair and skin.

Basically, a humidifier would do wonders for any home in an arid climate. An air purifier-humidifier combo would be able to address all these problems effectively, so if you’re facing any or all of the problems mentioned above, then an air purifier-humidifier combo is the answer.

The pros and cons of air purifier-humidifier combos

Pros Cons
Air Purifier-Humidifier Combos
  • Cost Effective
  • Convenient
  • Address More Problems
  • Generally expensive
  • Not as effective
  • High-maintenance

Other things to consider

It is also important to note that while air purifier – humidifier combo’s do have both advantages and disadvantages (as we have highlighted), if you find that the cons outweigh the pros, there is always the option of purchasing a single humidifier and complementing it with a standalone air purifier. While we believe a combo will do the job in most scenarios (and we have mentioned that buying separately will be costly) – if you are looking for a solution that will provide a bigger impact, you could always invest in separate products to give you more flexibility. It is simply a question of whether you have the space, the cash – or the inclination to spend more on your energy costs; as running two machines can be more expensive than running one!

FAQ

Are air purifier – humidifier combos as good as their separate counterparts?

This all depends on what you want to get out of your machine. If you are not looking for heavy duty humidification, or just light level purification – then a combination machine might be just right for you.

But as we have mentioned already, a combination air purifier and humidifier doesn’t clean the air as effectively as an air purifier – nor will it humidify the air as well as a humidifier.

Can air purifier – humidifier combos improve health?

Having an air purifier and humidifier at home can help to improve health. This is because it will provide the benefits of an air purifier – such as lowering VOCs concentrations in your home, reducing the number of dust particles in the air, and help to eliminate microscopic particles like germs and bacteria. Plus, you get the added benefits of a humidifier too!

If you suffer from eczema, psoriasis or acne, dry air can compromise your skin health, so a humidifier can help to combat these. It is worth noting, however, that a combination machine may not be the best option if you are suffering from serious skin conditions or allergies; as these types of machine are not as effective as their standalone counterparts.

Are air purifier – humidifiers easy to maintain?

This can depend on the make and model – but as we have stated, the maintenance on one of these machines is twice as much as their single function counterparts (because it is effectively two machines in one).

Some models, such as The Boneco Air Washer W200 are marketed as low-maintenance, while others, like the Dreval D-950 are high maintenance; which needs it’s filters changed regularly.

Final Thoughts

Clean air is a must for every home, yet seasonal changes and pollution bring about air quality problems that can cause discomfort for everyone in the family. Having an air purifier and humidifier at home can easily address these problems, but having to purchase two different units that serve two different uses can be inconvenient, expensive, and take up a lot of space. An easy way around this problem is the purchase a combination air purifier and humidifier, which is able to both purify and humidify the air.

Overall, we believe the best air purifier-humidifier combo is the Sharp KC-860U Plasmacluster. Its robust performance in both air purification and humidification strikes just the right balance between the two without sacrificing form or function. Its features are sufficient to make it more convenient to use without being too complicated. Once you get over the initially shock that the price tag will undoubtedly give you, you’ll realize that the KC-860U can be a very valuable addition to your home.
