Best Air Purifier and Humidifier Combo 2019 – Reviews and Buying Guide

When it comes to your health and comfort, the quality of the air in your home plays a vital role.  However, many of us do not look at many ways to improve it, beyond regulating the temperature.  However, there are many ways you can take control of the air you breathe while at home.  One such way is to purchase the best air purifier and humidifier combo. 

Best Air Purifier and Humidifier Combo 2019

Air purifiers and humidifiers do very different jobs, but their jobs complement each other.  Air purifiers help to remove things like germs, pollen, dust mites, and other irritants from the air while also improving the smell of the air you breathe.  Humidifiers moisturize the air, helping to keep your skin and mucous membranes hydrated, reducing symptoms of respiratory illnesses, bloody noses, chapped lips, and various skin conditions.  This means that both improve your health and your comfort level.

While it used to be that you needed to buy two devices to enjoy humidification and purification, this is no longer the case.  Now you can get the benefits of both types of machines in a single device.  Of course, navigating the purchase of a combination model is a bit more complicated than just buying one or the other.  To help you determine what makes a good air purifier and humidifier combo, read our guide below. 

Benefits of Humidifiers and Purifiers

When customizing your home, you pay attention to things like wall colors, furniture design, and accessories.  However, for maximum comfort and health, you want to control the air in your home as well.  Chances are you already do this with your thermostat, fans, and space heaters.  However, even if you do not have any specific health concerns, air purifiers and humidifiers add another dimension to customizing your home.  To understand why you would want both a purifier and a humidifier, let’s take a look at what they offer you. 

Air Purifiers

When things are clean, they are healthier.  This applies to everything in your home, including the air you breathe.  When it comes to keeping your air clean, there is no alternative to using a purifier.  Some benefits you can enjoy from using an air purifier include:

  • Reduction in pet odors, from body odor to litter box smells
  • Removal of allergy triggers from their air, including dust, dander, and mold
  • Filtering of bacteria and viruses, keeping your home healthier overall
  • Lessening of smoking odor in smoking homes
  • Elimination of body odor in gym spaces


Humidifiers can clean your air to a degree.  However, since they are not really processing the air in your home, models that are germ-free or use filters only clean the air they output, not the entire room or home.  With that said, the advantages they offer are still there, but different from those purifiers offer.  Benefits of using humidifiers include:

  • Skin hydration, preventing cracking and chapping and even helping to ward off eczema flare ups
  • Less static electricity in the home, lessening shocks and static cling
  • Moisturized mucous membranes, making breathing easier and boosting the immune system
  • Increased lifespan for wood furniture, window frames, and door frames
  • Reduced asthma symptoms in babies, children, and adults

Why Purchase an Air Purifier and Humidifier Combo?

While the benefits of owning these two items are clear, what isn’t so obvious is why you should opt for a combination unit over two separate machines.  In truth, there is nothing wrong with purchasing these items separately.  However, there are some benefits to combination units, including:

  • Less Money Spent: Because you are purchasing one item instead of two, your purchase will cost you less.
  • More Space Available: Combination units are slightly larger than your average humidifier.  However, you would be taking up much more space by having two separate items. 
  • Less to Think About: Rather than cleaning, running, and maintaining two devices, you only need to focus on one.
  • Lower Energy Bills: Because the two components can share a power supply in a combo unit, they use less power than if they were separate. 

What to Consider When Buying an Air Purifier and Humidifier Combo

When looking at combination units, you need to understand the features of the two elements: the humidifier and the air purifier.  Combining the two, there are many variables that can help you choose between two models.  However, we feel that there are four primary features you should look at before you buy: the type of humidification technology used, the square feet covered, the noise level of the machine, and the type of filter used. 

Type of Humidification Technology Used

There are four primary types of humidification technology you will find when looking for air purifier and humidifier combos: cool mist evaporative models, cool mist ultrasonic models, warm mist ultrasonic models, and steam warm mist models.  There are also some models that are both warm and cool mist; these use ultrasonic technology.

All of these types of humidifiers work well.  However, you may want a specific type due to health or safety concerns.  Warm mist humidifiers are great for loosening up congestion, but it is bad for those with asthma, COPD, and eczema.  It is also a concern around children and pets.  A cool mist humidifier is safe in all situations, but isn’t as effective at breaking up congestion.  Ultimately, the right choice for you comes down to personal preference. 

Square Feet Covered

This feature is pretty self-explanatory.  Essentially, you need to make sure the unit can take care of the air in the space you want it to be placed in.  Most single-room humidifiers can handle an average-sized bedroom or office.  If you are looking to put it in a larger room, you need to make sure it can cover more square feet.  Something else to consider is that higher ceilings will necessitate more coverage.  If your ceilings are taller than nine feet, increase the coverage you are looking for. It is also possible to find units that cover the whole house.

Noise Level

When you have two machines in one, things can get noisy.  But chances are slim you will be placing the unit anywhere that additional noise is considered a good thing.  In the bedroom, you need your sleep, in the office, you need silence, and in the living room, you need to be able to hear the TV and stereo.  To make sure your combination machine isn’t going to disturb you, look for those with special features that help them run quietly. 

Type of Filter

Finally, since your machine is purifying the air you breathe, you want to make sure it is doing this the right way.  In general, you will be looking for machines that offer HEPA filtration.  However, there are alternatives, including that that do not use any filters at all, relying on a special type of cleansing instead.  If you are seeking an air purifier and humidifier combo for health reasons, you might want to ask your doctor why type of filter is best for you.

  1   Venta Airwasher 2-in-1 Humidifier & Air Purifier

If you are looking for an option that does not use a filter, consider the Venta Airwasher.  Despite not having any filters or cartridges, it removes the vast majority of impurities from the air in rooms up to 400 square feet.  Rather than relying on filters, it uses internal disks that trap impurities and then run them through water, essentially washing them away. 

If you like this unit but have a larger space to purify and humidify, there is a model that can handle up to 800 square feet of space.  Also, if 400 square feet is too much, there is a 200 square feet model.  It comes with several features that make it easy to use, including a low water indicator and an auto shut off.  The fan can be adjusted to three different speeds to control the humidification and purification.  In general, you will get the best results on medium or high fan settings.  As far as trusting in the product, it comes backed by a 10-year warranty, so you can feel secure in your purchase. 

  2   Dreval D-950 Air Purifier True HEPA Filter Humidifier UV Light Negative Ion Generator Combo

When looking for a combination unit, one of the first things you want to know is how well it purifies the air.  Well, it doesn’t get much better than the Dreval D-950, which offers a 99.7% purification rate.  The cold catalyst filter is designed not to just remove debris from the air, but dangerous gases as well.  It can pull benzene, hydrogen sulfide, and other gases out of the air, decomposing them into a byproduct that is perfectly harmless.  This filter can last five years.

It also comes with activated carbon and HEPA filtration, which works to keep the debris out of the air and keep you breathing easy.  It is also antimicrobial, eliminating bacteria, viruses, and spores.  It even has an odor sensor, so when it notices something smelling off, it kicks in and removes the smell from the air.

The humidifier function is designed to keep your home at optimum humidity levels at all times; you do not need to monitor levels and adjust the unit.  It can humidify and purify rooms ups to 430 square feet and runs incredibly quiet.  Covered by a 2-year warranty, you can count on this combination model. 

  3   Sharp KC-850U Plasmacluster Air Purifier with Humidifying Function

If you want a device that improves your air while not detracting from the looks of your home, try this model from Sharp on for size.  With its slim design, it is easy to place it out of the way.  And even if it remains visible, its minimalist profile helps it blend in with its surroundings.  Also helping it work in most any space is its noise level, which is so quiet it practically makes no sound at all. 

This model cleans the air in two ways.  The first is with patented plasma caster technology.  This releases ions into the air that interact with the water vapor, producing hydroxyl which oxidizes pollutants.  It does not come with as many features as other models, but this helps to give it a thin and minimalist profile.  The second is the powerful HEPA filter.  This unit is a great option for smaller rooms, up to 250 square feet in size.  The product is covered by a warranty, but to get the details, you must contact the manufacture. 

  4   Oreck WK15500B Air Refresh 2-in-1 Hepa Air Purifier & Ultrasonic Humidifier for Small Rooms

While Oreck isn’t known for its humidifiers, it is known for its air purification technology, in both vacuums and purifiers.  So it isn’t a surprise that they would create an excellent air purifier and humidifier combo.  Many users note that it is incredible at relieving allergies and clearing smoke smells in their homes while also helping moisturize the air.  Once again, this is an option best for small rooms, at around 250 square feet or less.  If you are looking for an air purifier and humidifier combo for baby, this is the one we recommend as it is a good size for nurseries. 

The design of this Oreck model is quite modern, so if you have a more traditional design, you might want to look into other options.  However, it is very sleek and slim, making it easy to place within the home.  It uses a two-stage HEPA filter to ensure the cleanest air possible.  It is covered by a 2-year warranty.

  5   Innoo Tech Ultrasonic Air Purifier and Humidifier

Finally, we have this model from Inoo Tech.  Sporting a futuristic look that is somewhat robotic and rather cute, it works well in many spaces, including children’s rooms.  This model offers more flexibility than most as you can operate it as a cool mist or a warm mist humidifier.  When the tank is empty, the humidifier will shut off, but the purification will continue to work. 

This model uses a HEPA filter to filter the air as well as a powerful filter to filter the water.  Where it really stand out amongst the competition is that it also allows you to use aroma therapy and essential oils.  Below the humidifier is the aroma box and pad, making it easy to use oils to treat cold symptoms or just make your home smell nicer.  As with all Innoo Tech products, it is covered by a 1-year limited warranty.

Final Words

If you want your home to be a place of health and comfort, look for the best air purifier and humidifier combo for you.  While there are many options on the market, we believe the five we have picked are the very best and that one of them will be great for your home.  So happy shopping, and enjoy your new purchase.
