When poor air quality has a negative effect on your health, the best defensive strategy is to both filter the air and control the humidity level. But who has room for several bulky machines in every room of the house? Thankfully, there is a solution. We have found the best air purifier and humidifier combination units available today.
Allergy sufferers of the world know – air quality can make or break your day. Whether it is a high pollen count or some sort of environmental toxin (smoke from increasingly frequent forest fires is a good example), the result is the same.
Poor air quality will cause a scratchy throat, itchy eyes, crackling lungs, and difficulty breathing. Unfortunately, environmental pollution is even responsible for approximately 7 million deaths worldwide every year.
Protect your health and that of your family by utilizing tools that control the quality of air in your space. We have gone on a search for the best air purifier and humidifier combo on Amazon and found five great options. Any of the products on our list will increase your comfort several times over.
How Humidity Relates to Health
When it comes to humidity, a rough guideline for human comfort is somewhere between 30-60%. Keeping your home consistently within this level makes everyone less prone to seasonal infections and illnesses. Humidified air is more easily breathed and can also reduce dry skin, sore throat, and congestion. These benefits combined are likely to improve sleep quality, too!
Proper humidity levels are especially important for people who suffer from asthma. Asthma attacks are dangerous, scary, and painful. Asthma is when the inside walls of the body’s airways are chronically sore and swollen. When these sensitive passages are exposed to environmental irritants, they become even more swollen. This limits the body’s ability to take in enough oxygen and the “attack” is when a person is struggling to breathe.
Humidifiers help because moist air tends to relax the lungs and improve breathing. Humidity itself is also a natural air purifier as the water droplets can bind with environmental irritants and keep them low to the ground, rather than continually circulating in the space. In contrast, really dry air can spark irritation of the nerves in the lungs. That exacerbates inflammation and constricts the airways.
Benefits of Using an Air Purifier
There are plenty of benefits of using an air purifier, whether or not you suffer from allergies or asthma. It is simply a healthy habit that can reduce stress on your lungs and airways, not to mention your eyes. If you do have a condition that is aggravated by polluted air, running an air purifier will reduce your symptoms significantly. There are also benefits of an air purifier for baby because infants have much smaller airways and can get congested quite easily.
You can tell by examining a shaft of sunlight that dust is floating in the air at all times. And every time you walk through a room, more dust and other pollutants are stirred up. Running an air purifier greatly reduces the amount that you end up breathing in. Even if you don’t have an allergic reaction, your body does work hard to prevent airborne pollutants from causing internal harm.
Finding the Best Air Purifier and Humidifier Combo
No matter where you live, managing the air quality in your home can relieve a lot of painful symptoms. To save space, money, and effort, it’s great to purchase a machine that can both humidify and clean the air at once. There are some important features to consider, however. We’ll break them down below.
There are actually five commonly-used methods of air purification. For reference, they are basic and HEPA filters, ionizers, electrostatic filters, activated carbon filters, and UV lights. Stick with us after the reviews for more in-depth information about each type.
Note: if you are looking for the safest air purifier for babies, it is best to avoid an ionizer. These can bother some people, and babies have such small air passages that it’s better not to risk it.
Most air purifiers will report a CADR rating. This stands for Clean Air Delivery Rate and it demonstrates what level of harmful particles can be removed from the air by the machine. Put another way, CADR tells you how fast the unit can clean the air within a specified area.
CADR is reported in cubic feet per minute and typically refers to a purifier’s ability to manage pollen, smoke, and dust. These are pollutants that are both small in size and particularly irritating to humans. The better the CADR rating on any given air purifier, the faster and more effectively it can improve your breathing.
Each unit is rated to work ideally in spaces up to a certain size. A smaller machine can work well in a bedroom or bathroom, while you will probably need a larger unit to properly purify and humidify an open concept living room and kitchen. To cover the entire house, chances are high that you’ll need more than one humidifier/purifier combo.
Some air purifier humidifier combo units make low “white” noise while others can be quite noisy. If you are bothered by noise in general, be sure to read the user reviews on any product you consider. Some units start out quiet but are prone to developing rattles in the fan assembly as time goes on.
To lower your operating costs, make sure to choose a model that features the Energy Star logo, meaning that the unit adheres to strict energy efficiency criteria set by the US Environmental Protection Agency or the US Department of Energy. This saves your wallet and the environment at the same time.

Best Air Purifier and Humidifier for Baby Product Reviews
Following are in-depth air purifier humidifier reviews for each product, based on reports from real users.
1 SHARP KC850U PlasmaCluster Air Purifier Humidifier for Home Office Smokers Allergies and Pet Hair, 254 Square Feet
If air purification is your first priority, this Sharp air purifier and humidifier may fit the bill. It features the exclusive patented PlasmaCluster, an ionizer that eliminates the type of microscopic pollutants that are not caught by traditional filters. But this unit has one of those, as well, in the form of a HEPA filter to catch all of the larger particles.
But the Sharp doesn’t stop there. It also contains a pre-filter containing activated charcoal to trap dust before it reaches the HEPA filter and to remove odors from air that passes through. Given that the HEPA filter alone can remove about 99% of particles sized 0.3 microns or larger, this triple filtration system is top of the line.
Operation of this purifier/humidifier combo is a breeze. There are multiple settings that control the fan speed and light brightness, but you can also simply set it for auto operation. In this mode, the fan speed automatically toggles up and down based on the detected level of impurities in the air.
Cleaning is also relatively simple with a quick clean mode. Ongoing operating costs are low as the original HEPA filter can work for up to five years before it needs to be replaced. In terms of power needs, this unit has received the Energy Star rating.
- Air filter can run independently of the humidifier
- Original filter lasts for 5 years
- Responsive sensor adjusts fan speed depending on pollution level
- Water tank may need to be refilled frequently
- No way to adjust humidity level
- Signal lights on unit can disturb very light sleepers
2 KLARSTEIN Monaco • Ultrasonic Humidifier • Ionizer • Air Purifier • Built-in Filter • Bacteria, Odor, Dust Remover • Blue LED Display • Timer Function • White
The Monaco uses ultrasonic waves to transform water into a very fine mist that floats throughout the space rather than immediately settling on furniture and carpets. It also has dual mist nozzles that can be rotated to the optimal position for your room. This product works almost silently and has an intelligent feature that automatically adjusts to the room’s conditions.
Though humidifying is the primary function of this machine, it also removes dust, pollen, and other pollutants from the air with an antibacterial filter. To go a bit further, you can choose whether to engage the advanced ionizer, which breaks down the molecules that cause odors and removes them from the air.
There are three power levels and an optional blue LED light in the roomy 1.6 gallon water tank for mood lighting. A convenient remote control makes setting this unit simple and practically effortless. Operating costs are low as the included charcoal filter can be rinsed and reused several times. Weighing in at less than five pounds, this model could serve as a great desktop air purifier and humidifier, too.
- Air filter and humidifier can run independently
- Intelligent function adjusts to room conditions
- Easy to set up and use
- Can be challenging to refill water tank
- Not all lights can be dimmed; may be disruptive to light sleepers
- Humidity level readout may not reflect the entire room
3 Dreval D-950 Air Purifier True HEPA Filter Humidifier UV Light Negative Ion Generator Combo - Best Air Cleaner to Protect Against Allergens Dust Pollen and Mold - Built in Odor Sensor
The air purification system on this Dreval product has an astonishing 7 stages. There are four types of filter: cold catalyst, activated carbon, true HEPA, and antimicrobial filter. Beyond that, the unit features a UV light, an ionizer, and an ultrasonic humidifier.
This product also contains an odor sensor, which reads the breathing quality of the air and uses a 3-color system to report it. Red indicates poor air, orange is normal, and green is excellent. The speed of the fan is automatically toggled up when air quality is poor.
The combination of these features ensures that up to 99.99% of airborne pollutants will be removed from your space. You need never worry about bacteria, gaseous chemicals, VOCs, viruses, mold, dust, or pollen when your Dreval is running.
Users report extremely quiet operation and a large effective area of 430 square feet. The included remote control makes it easy to toggle settings from across the room. But because there are many different features to utilize, there is a bit of a learning curve to using this machine.
Another common complaint is the size of the water tank – it’s on the small side as air purification is the primary function of the unit. We were unable to verify the exact capacity of the tank; it does not appear in the user manual for the product. However, users suggest that it will be necessary to change the water a couple of times per day if the air is dry.
One other thing to consider with this humidifier/purifier is the usage cost. Many of the filters will need to be replaced every so often, so be ready for that expense in order to keep the unit running.
- Powerful air filtration with a 7-stage system
- Whisper quiet operation
- Comes with a remote control
- Higher maintenance costs for replacement parts
- Relatively small water tank
- Display lights are bright and sometimes flash
4 Oreck WK15500B Air Refresh 2-in-1 Hepa Air Purifier & Ultrasonic Humidifier for Small Rooms
Oreck does a good job of providing a humidifier/purifier combo unit that performs both functions well. With this product you have the choice to run just the humidifier, just the purifier, or both together. It may be the best baby air purifier because it does both jobs so well and does not contain an ionizer, which can bother some people.
The humidifier’s tank holds a gallon of water – not a huge amount but not impossibly small, either. It uses ultrasonic sound waves to release a fine, cool mist. You will also love the built-in humidistat that senses the room’s relative humidity. The vapor automatically switches on or off as needed to maintain your preferred moisture level.
The purification process relies on two stages, a charcoal filter for odors and a HEPA media filter to catch and retain 99% of airborne pollutants. Each filter will need to be replaced eventually, but the unit has a digital readout to let you know when it’s time to change one or both.
This product is ideal for use in smaller rooms. It contains technology to keep the sound level down, so it should not disturb even light sleepers in bedrooms or nurseries. A sleep mode is provided that dims all lights and keeps the fan running on low.
- Uses both HEPA and charcoal filters for powerful air purification
- Sleep mode function dims lights and reduces operating sound
- Built-in humidistat to control humidity levels
- Can be noisy on high speed
- Only works in relatively small rooms
- No automatic adjustment sensor
5 Venta LW25 Airwasher 2-in-1 Humidifier and Air Purifier in Black
The Venta LW25 is a solid humidifier that also purifies the air. It holds an ample two gallons of water per tank and can properly humidify large rooms up to 400 square feet. There is no filter in the design, however. It could be a great choice for people whose primary concern is moisture and who can be bothered by purifiers that create ozone.
The large two-gallon tank features a water level indicator and shuts off automatically when it runs dry. The method of purification relies on a series of rotating discs that dip repeatedly into the water tank. The wet discs are said to catch airborne pollutants in the environmental air that is blown across them. The particles remain behind while moist air is vented, and then wash off of the discs as they dip back into the water.
Debris therefore collects in the water tank, which needs to be cleaned carefully on a regular basis. The manufacturer recommends a branded ammonia solution for this purpose. Some users have complained that the cleaning requires more effort than they prefer.
Other than the ammonia solution, there aren’t any replacement parts to buy and the operating cost is pretty low. But it’s important to note that the level of air purification is also less than other units on our list. It could be best used in conjunction with other types of air cleansing.
- Energy efficient with no filters to replace
- Large two-gallon water tank
- Ideal for larger rooms
- Humidifies better than it purifies
- May develop a ticking noise with long-term use
- Cleaning is time consuming and requires an ammonia solution
We have talked here about combination units that both purify the air and add humidity. You may be wondering: Can you use an air purifier and humidifier together? The answer is yes, if you have the space for multiple machines.
One thing to remember when looking for a humidifier and air purifier combo is that no dual-purpose machine will work as well for both purposes as a machine dedicated to one purpose. If you feel like you need both humidification and purification in equal measure, it might be better to buy one of each type of machine.
However, most people will consider one or the other of these functions as a “bonus” that supports the primary need. If air purification is your main concern, choose a combo unit with a smaller tank but multiple layers of filtration.
If excessively dry air is the biggest problem in your space, you can look for a combo unit with a larger water tank and more basic filtration. But if you have plenty of floor or desk space available, you can certainly run a humidifier and air purifier in the same room.
Connection Between Pollen and Environmental Pollution
The World Allergy Organization reports that between 10-40% of the world’s population experiences pollen allergies. Allergy diagnoses have increased steadily in recent years and scientists have long suspected that this rising incidence is connected to air pollution. Though research continues, we know that the interaction of pollen, pollution, and weather in the environment can increase the length of each allergy season.
So while you might think of pollen allergies as being more troubling in rural areas with lots of plants, but the opposite is actually true. Urban centers tend to report greater levels of hay fever because vehicle and industrial emissions create something called photochemical smog. This pollution hovers overhead and keeps pollen lurking at ground level where it is breathed continually by humans.
Another way to describe man-made pollution is ozone, which forms when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources react chemically with sunlight.
Hovering around ground level, ozone is a dangerous air pollutant. It continually experiences chemical reactions that change its protein structure, making it more likely to bond with nitrogen dioxide. This potent combo is known to significantly irritate the human immune system.
Types of Air Purification Filters
There are five basic types, as follows.
Basic and HEPA Filters
Basic filters work when dirty air passes through dense yet porous material like cotton, fiberglass, or foam. The material traps particulate matter while clean air is vented out the other side. HEPA filters are the most powerful basic filters and can catch pollutants of at least 0.3 microns in size. Basic filters need to be changed once they fill up with particulate matter.
Ionizers and Ozone Generators
Ionizers and ozone generators work differently. They produce molecules that have a charge. When these charged molecules come into contact with airborne pollutants, which generally have a neutral charge, they get charged as well. That change causes them to stick to surfaces within the room, rather than remain airborne.
So while this type of purifier does clean the air, it doesn’t get the pollutants out of the space. Note that some people, especially those with respiratory concerns, may find that their lungs are irritated by ozone. If that’s the case for you, try to avoid an ionic humidifier air purifier.
A better way of using charged particles is via an electrostatic filter. These filters also charge neutral particles but then they trap them inside the machine. Some electrostatic filters are even able to kill the active microbe and mold spores it collects. You can then remove the filter plate and rinse it off before reusing. This type of filter does produce ozone, so might not be suitable for all people.
Activated Carbon Filters
This type of filter is often used in conjunction with other air purifying filters. Many of the products on our list include an activated carbon filter to deal with odors more than actual particles. It works because as stinky air passes through it, the gasses that cause the smell are removed. Using activated carbon in conjunction with another filter is a great way to increase your comfort and enjoyment of the purified air.
Ultraviolet lights are actually able to kill germs. Exposure will decimate microbes and even some viruses, thereby cleaning the air. It is more common to find UV lights installed in areas that tend to be damp and mold-prone than in consumer air purifiers.
However, UV lights can be a great addition to your efforts to purify the air in your home. Installing them in specific locations can reduce the amount of pollutants that become airborne in the first place.
Environmental pollution is everywhere and pretty much impossible to avoid. However, there is a lot you can do to treat the quality of the air in your home. When you find the right balance of cleansing the air and introducing humidity, breathing becomes easier and all of that uncomfortable itchiness and soreness eases.
Every case of allergies is different, of course, and you may still need to consult a doctor for advice on the right medication and diet to control your symptoms. But as soon as you start running the best air purifier and humidifier combo unit for your particular needs, you will notice a huge improvement. Order today and get ready to experience relief!
