The Honeywell 350 offers humidification using evaporative wicking filter technology. The required use of an evaporative wicking filter in this unit makes it less likely to create white dust, and prevents moisture accumulation on surrounding surfaces. We liked the Honeywell 350 for its ease of cleaning, but found that it was noisy and didn't provide some of the features included in our tested ultrasonic humidifier contenders.

Our Analysis and Test Results
As the only evaporative style humidifier in our testing bunch, it was easy to think that the Honeywell 350 might not be able to compete with the high-tech ultrasonic units during our testing. Surprisingly, the Honeywell 350's performance put it solidly in the middle of the pack.
Ease of Cleaning
Earning a score of 8 of 10 for cleaning, we found the Honeywell 350 to be extremely low maintenance. Apart from periodically refilling the water tank and wiping the base clean, there really wasn't much else worry about on a day-to-day basis. The Honeywell didn't have any of the difficult-to-reach areas and small spaces that some of the ultrasonic humidifiers had, and we could easily fit our entire hand into the water tank to clean it. As an added bonus, the instructions state that the base and tank are even dishwasher safe. Because it was so fuss-free, the Honeywell earned the highest score for Ease of Cleaning out of all of the units we tested.
Crane Drop Shape or Duux Ultrasonic. For parents concerned about water damage from mist droplets on furniture or flooring, this humidifier has a distinct advantage in limiting that possibility.
Vornado Ultra3, earning a 2 of 10. During in-home testing, we actually found the Honeywell's fan noise at the lowest setting to be soothing and felt that some parents may appreciate the added "white noise" benefit. However, at medium and high speeds, we were less excited about the added noise contribution while trying to sleep.
Ease of Use
With a 3 of 10 for ease of use, the Honeywell was super easy to operate because it has only one knob to select three choices for operation (low, medium, and high fan speeds), but it was not as easy to live with. We found that once the wick was completely saturated with water and ready for use, it was difficult to put the fan top over it because the wick wouldn't hold its form and kept getting squished out of position. Also, the Honeywell had the largest footprint of all of our humidifiers and required additional open space all around it so that the air intake would not be blocked.
We couldn't fit it on a standard night stand without taking everything else off, nor could we put it on our carpeted floor because the carpeting would block the vents. This unit would work best on a counter with plenty of extra space, or a hard floor. Finally, we found the UV light feature designed to reduce bacteria and viruses to be non-essential. The UV light technology claims to kill Up to 99.9% of certain bacterii, mold, fungi, and viruses in water after 2 continous hours of operation, but we were still skeptical. Most tap water is already treated to eliminate bad bugs, and the location of the light only treats water coming out of the tank. Although all of the water from the tank will pass under the UV light once, we were more concerned about the possibility of water sitting in the base for days after UV light treatment and then being soaked up by the filter.
Due to the large footprint, the Honeywell would be best in a room with lots of counter space, or a room where you could place it on a durable hard floor. If noise isn't an issue for you and you are most concerned about easy cleaning, this is the humidifier for you.
At around $80, the Honeywell 350 is neither the cheapest nor the most expensive humidifier of our bunch, One extra consideration in purchasing this humidifier is the additional cost of wicking filters which will set you back about $10 for each replacement. Honeywell does not put out a recommendation for changing the filter and user review recommendations range from every month to every season. We recommend checking the filter during weekly cleaning to look for excessive discoloration and dryness. As the filter collects more minerals from the water through evaporation, it will be less likely to "wick" or suck up water for effective humidity output. The before and after pictures below show you how the filter changed during nightly use over approximately two weeks. The picture on the right is after two weeks of use; you can see mineral deposit discoloration starting to appear at the top of the filter.
The Honeywell 350 is a good option if you are looking for an evaporative-style humidifier to eliminate white dust production and avoid the dampness that can accumulate on surfaces with an ultrasonic humidifier. However, for baby's room, we found that this humidifier didn't have the features that we craved and that its large size was less than ideal for fitting on a night stand or dresser.
