Best Water Air Purifier [8 Ultimate Suggests & Reviews]

  Mar 25, 2023 11:44 AM

Air purifiers are becoming increasingly popular, particularly in pandemic years. The best water air purifier employs water’s inherent cleansing qualities to filter the air while protecting the environment. 

As a result, we’ve compiled a comprehensive list of the top-rated water-based purifiers for 2021. Let’s check it out!

How Do Water Air Purifiers Work?

Air cleaner using water functions by following a natural process involving only a few stages: 

  • Polluted air is drawn into the revitalizer through a tiny input vent.
  • Then, it passes through the revitalizer circulating water. Contaminants are kept behind when the air passes through the water. 
  • The fresh, cleansed air is returned to the surrounding area. 

These revitalizers employ liquid as a natural filter to eliminate typical domestic air contaminants.

Purifiers pale in contrast to traditional HEPA purifiers that employ mechanical filtration. They were created expressly to remove the minuscule contaminants that affect houses. 

Water-based revitalizers, on the other hand, were created to make the atmosphere in your house cleaner and more pleasant to breathe by combining the following:

  • Light humidification: As they operate, they emit a small quantity of moisture, resulting in a minor rise in humidity. You cannot expect a revitalizer to perform and a humidifier in terms of controlling humidity in your house.

However, if the revitalizer is positioned close to you, you’ll notice the refreshing effects of greater humidity levels.

  • Light air purification: It would be impossible to expect water-based air cleaners to eliminate air contaminants with the same effectiveness as mechanical filtration because they employ water as a biofilter. 

On the other hand, these cleaners can remove typical air contaminants in tiny places and function particularly effectively when placed near your breathing room. 

  • Aromatization: Distributing the scents of essential oils is one thing a revitalizer excels at. Essential oils are compatible with most water-revitalizers, so a few drops in the liquid basin may make the atmosphere surrounding you even more refreshing and pleasant.

Buying Guides

Fan Speeds

You can customize the whirling speed of your water-based purifier with several fan speeds. As a result, you may modify the humidity and filtration levels to suit your demands and climate. 

Water Tank Capacity

Water-based purifiers have a reduced water tank capacity due to their compact design. Therefore, they require more frequent cleaning than other cleaners. 

To avoid this problem, choose an air purifier with a greater capacity, which will allow the machine to function more efficiently for extended periods. 

Extra Functions

Most of the best water based air purifiers on the market are relatively versatile: 

  • They can distribute aroma in space
  • Absorb moisture in dry places
  • Purify indoor air pollutions

Detail Reviews

In-Depth Air Revitalizer Review In 2022

1. EcoGecko Earth Globe


  • Brand: EcoGecko
  • Dimensions: 6.5 x 6.5 x 8 inches
  • Weight: 1.74 Pounds
  • Floor Area: 600 Square Feet
  • Water Tank: 30 ounces
  • Adjustable Speed: Yes

You’ll enjoy this EcoGecko Globe water-based air purifier since you can adjust the fan that sucks unclean air in and drives clean air outward. This compact purifier is ideal for small places since it efficiently neutralizes aromas in the home. 

It comes with a USB cable connected to an AC converter or a USB port hooked into a power outlet.  A plus is that the adapter comes in the box. 

It may also allow the usage of essential oils. Set it to the highest setting anytime the space needs a bit of extra freshness, and turn it down whenever you want a subtle aroma from the lavender oil in the package. 

As the name suggests, it has an orb-like shape and is powered by a blue LED light. For spaces up to 600 square feet, it also employs a liquid tank to capture contaminants from the atmosphere. 

The EcoGecko water globe air purifier, which measures 6.5 x 6.5 x 8 inches and weighs 1.74 pounds, is available in white, silver, or black and has a reasonable price tag. This feature makes it simple to place in practically any area of the home. 

It features a fan that circulates air through the water. Air flows through the liquid and is replaced by fresh, scented air because EcoGeco units filter air through water.

Besides, the blue light that glows through the water and essential oil is fascinating and adds a great touch to a place. 

The main drawback is that the orb becomes dusty after about two weeks of use and needs to be cleaned. Cleaning this device is also challenging because the internal parts are not liquid-resistant. 

To put it another way, if you get the engine wet, it might cause harm to the machine. So, when cleaning, remember to be cautious. 

The air purifier liquid splashes around when the machine vibrates as it does with the other water-based purifiers in this post. It may move as a result of this.

What we like

  • Reasonable price tag
  • Easy to transport thanks to compact design (6.5 x 6.5 x 8 inches)
  • Adjustable fan speeds
  • Pleasant LED light with various color options

What we don't like

  • Dirt and dust build in hard-to-reach spots
  • Prone to move

2. U.S. JACLEAN Aroma Globe


  • Brand: U.S. JACLEAN
  • Dimensions: 7.5 x 7 x 7.5 inches
  • Weight: 1.94 Pounds
  • Floor Area: 700 Square Feet
  • Water Tank: 16 ounces
  • Adjustable Speed: No

The Jaclean Globe water-based air purifier with water tank provides the idea of being trendy to have on your work desk. It adds a contemporary touch to the space without standing out too much. 

The water-based cleaner is a bit heavier than the EcoGecko, at roughly 1.94 pounds. It can cleanse the air in spaces as large as 700 square feet, making it an excellent scent diffuser for covering a large area.

It is almost too subtle; unless you get a great look at it, you cannot tell what it is. In any case, it is just 7.5 inches tall and 7.5 inches in diameter (as the name implies, it is globe-shaped).

So, this machine from the U.S Jaclean does not take up much space. It features a white lid and a transparent blue bulb that holds the liquid and aromatic oil. You may use the provided scent oils or add your own to the device, perfect for a home office.

It comes with three essential oil bottles, which are spread in the globe’s tank. The down stem rotates, stirring the mixture and emitting a mild, pleasant perfume into the air while sucking unclean air and impurities into the liquid. 

White noise is created by the slow droning hum of the stirring down stem. This Jaclean Aroma Globe helps eliminate allergies, air pollutants, and smells while providing a soothing glow. 

One of the disadvantages of this air purifier that uses water is that it tends to halt operating after six months. Some people have complained about it going down, though it does not happen very often. 

Another aspect of this revitalizer to keep an eye on is its movement on the ground. Since this purifier contains water and essential oils, it may occasionally move if the water splashes around, resulting in a mess.

What we like

  • Three included oil bottles for your preference
  • Can cover a room of up to 700 square feet
  • Easy to clean
  • Quiet operation (White noise production)

What we don't like

  • Prone to move
  • Sudden stop working after a period

3. ap airpleasure purifier


  • Brand: ap airpleasure
  • Dimensions: 8.43 x 7.52 x 7.4 inches
  • Weight: 1.74 Pounds
  • Floor Area: 360 Square Feet
  • Water Tank: 34 ounces
  • Adjustable Speed: No

The AP Airpleasure water purifier has a lot of appeals because it can eliminate a lot of smoke and odor. There is a lot more to it, which is why we chose this unit. Here are a few examples: 

It removes most allergens from the air, making it considerably healthier. Pollutants such as smoking, pet dander, odor, pollen, germs, mold, and other toxins will vanish. 

It is effective against 94.5 percent of subtle allergens, including small dust particles, CO2, PM 2.5, and other pollutants. Moreover, this machine purifies the air and provides a rainbow night light for a more relaxed atmosphere. 

There are seven different color selections to choose from to create the perfect atmosphere for whatever mood you are in. If you do not want the indicator lights on, you can turn them off. 

You’ll receive a multi-functional liquid purifier that can do more than absorb contaminants. Along with air filtration, it also functions as an essential oil diffuser. 

All you have to do is combine a few drops of essential oil with some tap water. A simple refill will keep it running for hours. 

It’s no surprise that this equipment can do even more where harmful ions come in. It will emit negative ions into the air, trapping positive ions and allowing you to breathe cleaner air. 

You may also mix swirling water, fragrance perfume, night light, and negative ions simultaneously. Despite emitting ions and having a plastic body, it is harmless because it is BPA-free. 

Aside from the energy-saving technology, you’ll receive a massive 1000 ML liquid capacity, and it’ll be straightforward to use. You can put it in any space, including the gym, bedroom, workplace, and living room. 

However, this water air purifier is almost perfect, except for the lack of white noise production.

What we like

  • Large water tank (1000ml)
  • Suit for any place (360 sq ft) from the gym to the living room
  • Better ambiance with pleasant aroma and night light
  • BPA free

What we don't like

  • Lack of white noise production

4. Bluonics Air Purifier


  • Brand: Bluonics Fresh Aire
  • Dimensions: 6 x 7 x 6 inches
  • Weight: 1.81 pounds
  • Floor Area: 360 Square Feet
  • Water Tank: 32 ounces
  • Adjustable Speed: No

Water-based cleaners are inexpensive when compared with other types of purifiers. We suggest the Bluonics model if you’re looking for a good water-based purifier for under $100. 

It is a fantastic water air revitalizer for small and medium rooms that purifies the air with hydro technology. To offer fresh air, it captures dust, smoke, smells, spores, and pollen. 

It filters, atomizes, and then returns the air to the room, resulting in a pollution-free atmosphere. You can pour several drops of oils into this purifier to give your space a unique scent. 

The unit will purify the air and remove pet smells, cooking odors, and any other undesirable odors from your home. Aside from keeping air pollution out, you’ll notice some multicolored LED lights that vary to give your space a lovely aesthetic. 

By creating fresh air, this portable water-based purifier with dimensions of 6 x 7 x 6 inches and a weight of 1.81 pounds is appropriate for persons with asthma and other allergic responses. 

For water-based odor elimination, the storage tank capacity is about 1 quart, which is adequate to cleanse rooms with total coverage of 360 square feet. 

This Bluonics Fresh Aire device works well for a decent period. However, if you run it continuously for a long time, it may malfunction. We cannot ask more for this affordable price tag.

What we like

  • Affordable price tag
  • Cleanse any unpleasant odor
  • Many LED light options 

What we don't like

  • Easy to malfunction after constant use

5. EcoGecko Green Leaf Revitalizer


  • Brand: EcoGecko
  • Dimensions: 8.75 x 8.75 x 7.63 inches
  • Weight: 1.5 pounds
  • Floor Area: 600 Square Feet
  • Water Tank: 60.8 ounces
  • Adjustable Speed: Yes

The EcoGecko Green Leaf Revitalizer is a compact purifier with 8.75 x 8.75 x 7.63 inches in size. This unit is 1.5 pounds in weight.

To operate this EcoGecko Leaf machine, connect it to an electrical socket, and you are good to go. The water bowl is clear plastic, so you can easily keep track of the liquid inside. 

It functions as a humidifier, air purifier, revitalizer, deodorizer, and aromatherapy machine. This ability makes it the best choice for versatility.

To eliminate undesirable smells, reenergize stale air, and provide a fresh aroma to any space, you can add a few drops of Lavender oil, which is included in the package.

The machine will draw air from the room into the spinning water’s base—the water functions as a filter, collecting pollutants and allowing fresh air to enter your space. 

This water air filter system includes a locking top to keep the water from spilling all over the place. Any interior space will be transformed into a tranquil area by the whirlpool of whirling water and shimmering blue light, perfect for relaxing. 

Moreover, when operating this purifier, you may hear a pleasant white noise (45 dB) created when the device is running. It creates a relaxing and quiet environment. 

A more extensive base can contain more liquid and covers around 600 square feet. When you lift the top, an integrated safety switch shuts the machine off. 

Moreover, this machine is straightforward to clean. Drain the water and replace it with new water and oils regularly. You should use EcoGecko oils since they are mainly developed for this system.

However, a few customers who suffer from allergies find it worse to smell the scents included. Since this unit needs plugging into the socket for operating, you cannot move it around the house while it is running.

What we like

  • Affordable price tag
  • Quiet operation (45 dB)
  • Easy to clean
  • Can cover a 600-square feet room
  • There is a Lavender oil bottle in the package

What we don't like

  • Not ideal scents for allergies
  • Cannot move around

6. Sirena Twister Purifier


  • Brand: Sirena
  • Dimensions: 9 x 8 x 9 inches
  • Weight: 2.33 pounds
  • Floor Area: 600 Square Feet
  • Water Tank: 68 ounces
  • Adjustable Speed: No

The Sirena Twister water-based purifier works similarly to other air cleaners in that it has a liquid tank that pulls air into it, trapping allergies, pet dander, and smells. 

Then it releases the same air, but with fewer molds and dust particles and adding moisture to the dry air. The cleaner is ideal for pet owners and smokers since it uses a simple water filtering mechanism. 

You may also add your favorite aroma oil to the device to purify the air and give a smell to your space. We recommend going with the eucalyptus scent; you’ll be happy because it will make the space smell and look cleaner.

The Sirena Twister Purifier also has an LED light to be used as a night light in your bedroom. Therefore, you may use it as a bedside lamp while also improving your sleep quality. 

You may also use this unit in the laundry room or any other room where pet hair accumulates, and you will notice a change after the first day. 

There is less fur floating through the air, and everything is cleaner. The level of noise is the most important consideration with this water air filtration

The top of this purifier creates a rattling sound, and its motor makes a buzzing noise.

It may not be the most excellent option for you if you’re searching for a water-based purifier fragrance diffuser that does not create any noise. 

With dimensions of 9 x 9 x 8 inches, this scented water-based purifier is enormous. This device is more prominent, noisier, and heavier than the top overall EcoGecko water-based purifier. 

It weighs 2.33 pounds. Finally, the product is housed in a glass bulb with a black top, but the LED light shines a beautiful bluish color when turned on, making it seem significant. 

Another versatile device is the Sirena water-purifier. This water-based unit sucks in polluted air into a whorl of spinning water and retains all allergens, rather than exacerbating your respiratory problem.

What we like

  • It can operate as a night light
  • Excellent performance for freshening the air 
  • Reasonable price tag
  • Compact design

What we don't like

  • Humming sound irritates people
  • Heavier than others (2.33 pounds)

7. Aprilaire Manual 500MZ 500M


  • Brand: Aprilaire
  • Dimensions: 10.25 x 15.63 x 13 inches
  • Weight: 7.75 Pounds
  • Floor Area: 3000 Square Feet
  • Water Tank: Using a running water line (12 gallons per day)
  • Adjustable Speed: Yes

This Aprilaire humidifier will monitor the interior and outdoor temperature and relative humidity. All you have to do now is set this manual purifier up, and it will adjust its function to the conditions in your home. 

You may also select from a variety of sizes. It comes in four dimensions and is designed for huge rooms. This Aprilaire 500 purifier is a whole-house ideal pick that can cover up to 3000 square feet. 

However, unlike other bulkier versions, it is not a massive thing. It features a tiny form that allows it to fit into small areas. It has a width of 15.6 inches, a height of 13 inches, and a depth of 10.4 inches.

The Aprilaire 500 is a lightweight purifier, weighing in at around 7 pounds. It also has a daily water capacity of 12 gallons. The Aprilaire uses dual sensors to keep track of the temperature and then adjusts the humidity accordingly. 

Because the Aprilaire 500MZ has a digital display that shows you the present humidity percentage. A Blower Activation switch allows you to configure the humidifier to operate all the time or only while the furnace is running. 

Although you will have to spend more money on this unit, the results will be worth it. It looks to be a simple gadget to use. 

What we like

  • Extended coverage for a large room up to 3000 square feet
  • Small design but powerful performance
  • Easy to use thanks to digital display

What we don't like

  • Hefty price tag



  • Brand: Venta
  • Dimensions: 11.8 x 13 x 17.7 inches
  • Weight: 13 pounds
  • Floor Area: 600 Square Feet
  • Water Tank: 384 ounces
  • Adjustable Speed: Yes

The LW45 is a good option if you need to cover roughly 600 square feet of space. Smaller Venta devices are available for smaller spaces. 

However, they lack some of the capabilities found on this LW45 (like only two fan settings instead of 3). Because the Venta water-based purifier is a solid option, it can hold up to 3 gallons of water, making it one of the most extensive reservoirs we have seen so far. 

The ease with which the Venta’s water tank can be refilled is one of several qualities that make this purifier one of the top selections on our list. With the Venta LW45, all you have to do is raise the lid, pour the liquid inside, and you are ready to go.

The clean output is then released into the air, which instantly refreshes the entire room. This implies that your allergies will not affect you as much as they did previously, and bacteria will not be a problem. 

The LW45’s operating panel is simple to grasp because of its simplistic design. The power switch is the first button, while the fan adjustor is the last button. 

Most customers will like the 3-gallon water tank, one of the largest currently available on an air humidifier. Moreover, those who were dissatisfied with its average performance commended the unit’s low-level noise production.

You can hardly know the gadget is functioning at its lowest fan speed, creating 24 dB noise. It’s surprising to learn that such a solid and flexible device as the Venta uses such little energy. 

The Venta uses as little as 8 watts even when the maximum fan setting is active, while the bottom two stages use 3 and 5 watts, respectively. 

Thanks to its low power usage, users may leave the humidifier running 24 hours a day, seven days a week, without a significant effect on the electric bill. 

The Venta LW45 is one of the most costly humidifiers on the market due to its numerous valuable functions. So, before you buy this device, think about your budget.

What we like

  • Generous capacity of 3 gallons
  • Act as an air purifier and a humidifier
  • Auto shutdown when the tank is empty
  • Quiet operation (24 dB)
  • Energy-saving

What we don't like

  • Hefty price tag
  • Not appealing appearance


1. Can A Water Air Purifier Replace A Humidifier?

Humidifiers are meant to dispense enormous volumes of water into the air. On the other hand, a water-based revitalizer discharges far less liquid into the environment of your house. 

On the other hand, a water-based purifier can surely benefit you if you require a minor increase in humidity in your room. Water-based revitalizers revitalize the air by cleansing and slightly humidifying it. 

Therefore, water-based purifiers will not perform as well as purpose-built machines (such as a humidifier).

They will do an excellent job of doing what they were designed to accomplish, which is to make the air in your house feel more pleasant. 

All you have to do is fill the purifier tank with water. The water-based filtration systems will need to be cleaned more frequently than on other purifiers. 

Humidifiers are frequently more effective than water-based air purifiers at humidification. Your best bet will be to buy two separate units.

2. Can A Water Based Purifier Replace An Air Purifier?

Water-based cleaners aren’t as effective at purifying the air in your house as a HEPA purifier. Nonetheless, these machines perform a decent job of purifying the atmosphere in your home. 

It isn’t easy to compare to a filter that represents the pinnacle of air purifier success. The main aim of a purifier with a HEPA filter is to purify the air in your house. 

But, there are many variations between the two machines that neither can perform all the tasks the other can. Each device has its own set of advantages and disadvantages! 

A water-based gadget, for example, is designed to clean the air in your house while also adding a tiny amount of dampness to make it seem more pleasant. 

3. How To Care For My Water Air Purifier?

Depending on how often you use this machine, we recommend cleaning the water tank weekly. In addition, we suggest cleaning your whole unit thoroughly at least once per month. 

Because your machine uses water, mold, fungus, bacteria, and other harmful organisms that thrive in damp environments might make it a perfect target. These creatures can overwhelm your equipment swiftly. 

If you don’t clean it correctly and frequently enough, they’ll utilize it to spread across your house as a jumping-off point. Cleaning an air purifier is similar to cleaning a vacuum cleaner.

Put your cleaner in a water bath with chlorine and read the instructions. However, if you take excellent care of your device and follow the manufacturer’s guidelines, you should not have to worry about this worst-case situation.

4. Who Are Suitable To Use Water-based Air Revitalizers?

These Water-based revitalizers are intended to serve those looking to make their surrounding air cleaner, more refreshing, and more fragrant. In particular, these systems would greatly benefit those who:

  • Have asthma and mild allergies

  • Working in enclosed locations where the air might grow stagnant is a risk
  • Smoke or live with smokers
  • Pet owners

5. Pros And Cons Of Having A Water Air Purifier?

As previously said, there are several benefits to utilizing a water-based purifier to improve your life and lower contaminants in the indoor air. This machine, however, has several drawbacks. 

Let’s look at the benefits and drawbacks of these cleaners.


  • They are less expensive than other types of air purifiers. 
  • Cleaning and upkeeping an air filter using water are simple. 
  • It is a multipurpose gadget that may be used as a humidifier, purifier, and perfume diffuser. Some types even include a handy LED for night lights. 
  • They run quietly and provide very little ambient noise. 
  • There is no need to invest money in new filters. Alternatively, refill the tank with freshwater. 
  • They are small and lightweight.


  • The tank needs cleaning regularly
  • They are not as effective at eliminating smells and filtering small particles as HEPA and carbon filters. 
  • Liquid leakage is a typical occurrence. 
  • Large rooms are not ideal for water-based purifiers. 
  • Bacterial and mold development might be aided by excessive moisture from the cleaner. 

Final Thoughts

We hope our suggestions can save your time and effort in choosing the best water air purifier. You can consider the EcoGecko Earth Globe for the best overall value or the Bluonics Fresh Aire if you are on a budget. All of them have excellent build quality and performance!
