Design And Usability
The most stylish, self-regulating, evaporative technology in the market. Honeywell HCM350 is a versatile UV humidifier that comes in either a black or white version. At a dimension of 15 x 23.6 x 8.2 in and 15.4 lb weight, it is not the most compact but certainly not bulky either. With barely any sharp corners, the ventless body defines well to the modern and stylish aesthetic. At the side, you have a transparent 1-gallon water tank with a wide opening for easy refilling. Carrying the water tank is also easy thanks to the large recessed tank handle. Overall, build quality is up there especially with our all-time favorite break resistant water tank.

Moving on to the top controls and moisture output area. Operating Honeywell HCM350B could not be any easier. The entire operation is predominant by a single dial knob that allows fan speeds adjustment. Turn the knob to the right to start the operation at low speed or higher. Turning it at the reverse order will reduce the fan speed or deactivate the machine. There is also a tiny reset button that can be press after you have changed the UV light.
Airflow, Coverage, And CADR
Given its compressed setup, it's no surprise that the airflow delivery rate and humidifying range is not that great. Honeywell HCM350B air purifier and humidifier limited coverage means it is only suitable for small room size. For optimum results, it is best to place it on top of the bedside table, top cabinet, or working desk. Honeywell HCM350 1 gallon water tank can run up to 24 hours per filling. While the output might not seem a lot, there are still 3 selectable fan speeds for you to tinker around with. Low speed is ideal for nighttime use, medium speed for everyday operation, and High speed or fast humidifying. Again, there is no autonomous mode so everything has to be done manually via the dial knob.

Filters And Performance
Besides helping you breathe and sleep better, here's the main reason why you should buy Honeywell HCM350B or HCM350W. It comes will the patented germ-killing setup that eliminates up to 99.9% of water-bred mold, bacteria, and spores. First, water in the reservoir will be sanitized by the ultraviolet light that kills virtually every microorganism in the water. With germs, fungus, and viruses out of the way, the wicking filter will start absorbing the germ-free water. Finally, incoming dry air will take in the moisture through the filter and emitted out as fine visible mist. The whole process will repeat itself until every last drop of the water is out.Noise And Energy Usage
The cool-mist name tag will give you the best assurance on Honeywell HCM350B silent operation. Adding UV-light sanitizing also produces zero noise output, this is the perfect air purifier humidifier to place it in your baby room. Power consumption is slightly high at 60 watts. This is partly due to the Ultraviolet light that requires more power than a non-UV model.Noise Type | Decibels |
---|---|
Breathing | 10 dB |
Rustling leaves | 20 dB |
Whispering/ Quiet library | 30 dB |
Light rainfall | 40-50 dB |
Conversation | 50-60 dB |

Honeywell HCM 350 VS The Challengers

Venta LW25 Airwasher Humidifier
About the same price, same cool-mist setup, and utilize a wicking filter. Humidifying performance is about the same but you are trading ionizer with UV light. Is it worth it? Only you can decide.
OPOLAR Evaporative EV01 Humidifier
Not exactly the same comparison as LW25 is much stronger in humidifying and bulkier but at a higher cost. Choose is if you are willing to forego the wonder ultraviolet light.Pros
- Cost less than 100 for a highly reliable UV air purifier humidifier.
- Germ killing UV light technology with a long-lasting 3,000 hours lifespan.
- Wicking filter that comes with two components: blue pre-filter for larger particles capturing and antimicrobial that inhibits bacteria and mold growth.
- Modern and sleek design without sacrificing the water tank size.
- 3 years limited warranty.
Cons
- Wicking filters requires replacing every 30-60 days which can be quite costly in the long run.
- No HEPA filter, carbon filter, autonomous purifying or any cleaning mode.
- Basic humidity function with no auto on/ off.
- There is no option to set the desired humidity level. Humidifying will keep on running until it is turned off.
