Our Verdict

The AquaOasis Cool Mist humidifier is a mid-level performer being offered at a low price point. It is reasonably effective at humidifying and has a relatively low overall operating cost. We enjoyed the simple control dial that lets you set the humidity levels to varying degrees of strength but we found that the shape of the device and the small opening make it extremely difficult to keep clean and to refill with water. This is a cost-effective and affordable option but there are better-performing models out there at a similar price point.

Our Analysis and Test Results

To get a clear understanding of the AquaOasis Cool Mist's performance, we submitted it to a series of standardized tests that let us compare it to other humidifiers in the most unbiased way possible. In our analysis, we considered metrics like humidifying performance, overall user-friendliness, ease of cleaning, and long-term operating costs. Read below to see the details of how it performed.

Humidifying Performance


The AquaOasis Cool Mist had mixed results in this metric. Its overall output was quite good. Over the course of three hours, it brought a room from 30.5% humidity all the way up 59.2% humidity, a 94% change. Its consistency, however, was subpar. As the humidity rose, the humidity levels fluctuated highly but ultimately ended up where they were supposed to be.

Ease of Cleaning


Humidifiers are the perfect breeding ground for mold. Being able to clean them properly is essential. The design of this machine makes it almost impossible to keep it clean. The issues primarily stem from the tiny hole that gives you access to the interior of the machine. It makes it incredibly difficult to get a cleaning brush into the device to scrub out mold. Compounding this is the way the interior was molded. There are difficult ridges to navigate and sharp edges that give mold and scum many places to hide.

The included instructions call for a weekly water change, but during our testing, we found this to be inadequate. We found that pink grime would start building up within two days if we didn't change the water daily.

User Friendliness


One of our favorite features about the AquaOasis Cool Mist is the easy-to-operate control dial. Turning it clockwise slowly ramps up the humidity levels. Many machines have specific modes, i.e., low, medium, high, but this dial really lets you fine-tune your humidity levels to where you want them.

Stemming from the same problem the device has with cleaning, the small hole that gives you access to the interior makes it challenging to fill the unit with water. The shape of the machine, in general, is unwieldy and hard to hold, adding even further difficulties to the filling process.

Operating Cost


Assuming 12 hours of use per day, it costs about $10 a year to run the AquaOasis Cool Mist. This is one of the more cost-effective options of any of the devices we tested. When tacked on to its fairly low MSRP, the overall lifespan cost of this model is quite reasonable.

Value


While the MSRP and average operating costs are low, we didn't find the AquaOasis Cool Mist to offer a particularly good value. Its issues with cleanliness were too notable to highly recommend this device over other similarly priced options.

Conclusion


The AquaOasis Cool Mist is incredibly affordable to operate but has serious issues with its ability to keep clean. The small access hole makes it difficult to get a cleaning brush inside, and the molded plastic doesn't make it any easier to scrub off mold when you do. The control dial lets you fine-tune your humidity levels, and the overall output is above average. All in all, this machine is affordable and functional, but given how difficult it is to keep, not one of the top recommendations.
