Our review of the Plasmacluster technology that has been fitted is that it works to get rid of microscopic pollutant particles. It is effective at eliminating various bacteria and viruses.

We were impressed with how the machine only produces 0.001ppm of ozone which makes it safer than many other ozone-producing air purifiers. A 3-stage filtration system is also available that includes a pre-filter, activated carbon filter, and a true HEPA filter.

  • Quiet mode available 
  • Permanent filter
  • Negative ion generator 
  • Easy to use LCD panel

The evaporation system available with the OPOLAR EV01 ensures that the mist released into the air is invisible. Many reviews of other humidifiers report that they can release too much mist. This machine also works great for preventing humidity from building up too much on surfaces around your home which is great considering how it’s a more inexpensive option.

We liked how the fan for humidifying air has been made with a quiet design. Therefore, you can install the machine in your bedroom to continue running while you sleep.

Furthermore, the nylon fiber filter that has been integrated is permanent. Users have been liking this feature as it makes the machine easier to maintain.

To make things even easier, you can remove the grill to have easier access to the water reservoir for refilling. The water reservoir has a capacity of 0.8 gallons so it may require more frequent refilling.

The review of the timer function that’s available is that it’s easy to use. You can use the timer function to set the machine to work continuously for either 2, 4 or 8 hours at a time. Furthermore, a negative ion generator is included which works to target airborne pollutant particles.

Users have also been liking how they can add essential oils to the aroma pad. These essential oils smell amazing and can provide you with health benefits.

Air Purifier & Humidifier Combo Buyer’s Guide

Water Tank Size

The size of the water tank will vary depending on the model that you choose. When it comes to using air purifier humidifier combo machines in smaller spaces, the ones with smaller tank capacities are cheap and often below 1-gallon which may be viable.

However, when it comes to medium and larger sized rooms, you’ll want to find the best air purifier and humidifier on a higher budget with bigger water tanks. This is because these machines will be using up more water faster to effectively moisturize the air in your room. Therefore, the larger tank prevents you from having to refill it too often.

The air purifier humidifier combo machines that are larger can be more difficult to move around when you need to refill them. Whereas you can have an easier time refilling the smaller models in the sink and putting them back into place. 

Humidifier Runtime

When you’re looking at the runtimes for air purifier and humidifier combo machines, the size of the tank and fan speeds will have a big impact. Large room humidifier and air purifier machines last longer than ones with smaller tanks as there’s more water to use up.

However, be sure to keep in mind that when you’re provided with the statistics on runtimes for these machines, they are usually for when they’re being run on the lowest fan setting. Therefore, if you use it on a medium or higher fan speed, it will use up more water in the tank faster and the runtime may be less than you were anticipating.


Before you make a final decision on a humidifier air purifier, you’ll want to consider how much space it’s able to effectively cover. If you use a machine that’s meant to be used in a much smaller room to the one you’ve set it up in, the machine won’t be as effective as it could be.

The airborne pollutant particles won’t be able to be filtered properly and the air will still be dry in areas. Therefore, we recommend that you find an air purifier humidifier combination machine that’s appropriate for the size of the room you’re planning to use it in.

Air Purifier vs. Humidifier

Air purifiers work by getting rid of pollutant particles in the air, such as pollen, pet dander, dust, smoke, and more. They use fans and filters to suck in air which is cleansed from pollutants before being released back out.

Humidifiers work to increase the moisture in your air. They have water tanks that they’re able to convert into steam through evaporation to be released into the air. As a result, they can help with cold symptoms and dry skin.

Humidifiers can be best for babies as it prevents cold symptoms and helps them to breathe easier. Asthmatics can also benefit greatly from humidifiers as they’re able to breathe better.

When it comes to allergies, dust, pet dander, mold, smoke, and odor-causing particles, air purifiers work best.

Tips On Using 2 In 1 Air Purifier & Humidifiers

  • Regularly cleaning your air purifier humidifier combo machine is critical to prevent mold and bacteria from building up. 
  • If you want to moisturize your air and purify it while you sleep, be sure to pick a machine with a sleep mode or a low fan setting. This reduces the noise it makes so you can sleep soundly while it works through the night.
  • We recommend that you don’t have the machine switched on any longer than the recommended time for your model to prevent it from overheating.
