Top Water Air Purifiers, According to Reviewers

Water-based air purifiers have a lot of advantages over standard air purifiers because most of them are multi-function. Many of them act as a humidifier and/or air freshener as well as an air purifier. They can be a godsend for smaller spaces that tend to get stagnant or rooms that don’t have good ventilation. We grabbed some of the best water based air purifiers and tested them in our own home to see which ones made the grade and which ones didn’t. Check out our pick for the best water air purifier.

What to Look for in a Water-Based Air Purifier?

Water-based air purifiers sound great but they can actually become a handful if you don’t buy a good one. Trust us, we tested at least 5 other products, not including the ones that made it on our list and were greatly disappointed. Some of them accumulated way too much gunk in the bottom of the reservoir bowl. Others were too loud and some were just ineffectual. So through our experience, we came to understand which features to look for in a water air purifier. Look for these features to ensure you get a quality machine:

  1. A sturdy reservoir bowl
  2. Multiple fan speeds
  3. Quiet operation
  4. A water agitator device

Our first impression of the Jaclean Aroma Globe water air purifier was that it looked really cool. In fact, when it arrived, we were pretty psyched to put it on the desk of our home office. It lends a modern flair to the room without standing out too much. It’s almost too covert as you can’t really tell what it is until you get a good look at it. At any rate, it stands 7 inches tall and 7 inches in diameter (globe-shaped as the name suggests) so it doesn’t take up much room.

But it is rated to purify the air in rooms of up to 700 square feet so it covers a good amount of ground. It comes with 3 bottles of aroma oil which are diffused in the water reservoir at the bottom of the globe. The rotating down stem stirs the mixture, releasing a light, pleasant aroma into the air while drawing in dirty air and contaminants into the water. The gentle droning noise of the rotating down stem doubles up as white noise too.

Using the Jaclean Aroma Globe will reduce allergens, air contaminants and odors, while also contributing a calming light to the area. Great for the bedside table, you can use the include aroma oils or add your own to the device.


  • Comes in 4 different light colors
  • You can add as much or as little scent as you want
  • Easy to clean 


  • Some users experienced vibrational noise
  • Can’t turn off the lights or adjust the speed

The Sirena Twister water-based air purifier works in the same way as our last entry: there is a water reservoir in the device that draws air into it where allergens, odors and pet dander are trapped. You can also add a number of scents to the water of the Sirena Twister Air Purifier. We chose the eucalyptus fragrance and were very pleased with it. It made the room smell and feel cleaner. The Sirena Twister Air Purifier works with an LED light as well so it made a nice little night light for our little girl. It runs very quietly too and is very compact so it’s easy to move from room to room.

We also put the Sirena Twister Air Purifier in our laundry room where our dog likes to sleep (coincidently, the room that gets the most dog hair, go figure) and we noticed a difference after the first night. The air was clearer and there was less fur floating in it.


  • The LED light can be changed to 7 different colors
  • Stands only 9 inches tall
  • Great for freshening the air in small to mid-sized rooms
  • Can add scented deodorizers which contribute a subtle aroma to the air


  • Can not turn off the light
  • Some users report that the device is too loud for overnight use
Best Price

We really liked the EcoGecko earth Globe water based air purifier because you can actually adjust the speed of the fan that draws dirty air in and propels clean air outward. So when the room needed a little more freshness, we set it to its highest setting and we turned it down when we just wanted a light scent from the lavender oil it came with. 

As the name implies, it sports an orb-like design (think Death Star but not so drab or imposing) and operates with a blue LED light. It also uses a water reservoir to trap contaminants in the air for rooms of up to 600 square feet. And if you prefer to use essential oils, the EcoGecko Earth Globe can accommodate.


  • Very easy to set up and clean
  • Sports a cool design
  • Adjustable fan speeds


  •  Noisier at higher speeds
  • Dust and dirt collects on the inside in hard to reach areas

Frequently Asked Questions

Are water air purifiers effective?

Yes, they are very effective for trapping dust, dander and allergens so that they are not simple re-released into the air. They can also be effective for room humidification.

How do you clean a water based air purifier?

Most water based air purifiers feature a detachable reservoir bowl or bottom portion. All you have to do to clean it is carefully detach it, dump the old water out, clean it with a sponge or rag and a mild detergent, rinse it and set it to dry.

Can air be filtered through water?

Yes. When air is passed or forced through water, the contaminants it contains are flushed out and trapped in the water. Water can be a very effective filtration system for larger contaminants and particles in the air.

Last Words

It should be noted that all of the products on our list are suited for small to medium-sized rooms. We were only able to test water-based air purifiers in small to medium-sized rooms so we opted for products that were rated for smaller areas. That being said, these were the 3 best performing devices we came across in our testing. These are all great products to have; especially if you like to keep your rooms properly humidified. They are pretty much essential if you have a pet and there is a lot of fur floating through your indoor air. These are definitely the best water air purifiers available today so be sure to check them out.
