Honeywell HCM-350 Review: Affordable And UV Ready!

A device that neither resemblances an air purifier or a humidifier. Honeywell HCM350B or HCM350W is a one of the kind, germ-free cool mist humidifier. Unlike other air purifier humidifier that heavily relies on a conventional filter, HCM350 setup is very simple. It uses ultraviolet light, a wicking filter, and a water tank. So how does this mini UV humidifier fares compared with a HEPA air purifier? Can it reduce static electricity, relieve nasal congestion and cough? Find out in our full review below.

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.

Honeywell HCM350 Control Panel

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.

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.

What’s inside count

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.

Keep it down

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.

^ Replacement filters/ estimated cost
You would think an ultraviolet device would cost you at least more than 100. Honeywell HCM-350 UV dehumidifier once again surprise everyone with its super affordable price tag. You could easily get one online between 60-80 dollars. As for the maintenance, replacing the UV light bulb is no issue at all with its 3,000 hours lifespan. However, the wicking filter can be costly to replace as you will need to fork out 11 dollars every 30-60 days. We recommend replacing it sooner rather than later to avoid mold and bacteria growth on the machine.
Honeywell is a major brand thus you can easily purchase it at any channel. Out of the many sites we compared, Amazon has the best deal for Honeywell HCM-350, especially during the festive season. Alternatively, you can purchase from Honeywell official website as the price does not sway too far from Amazon. Lastly, visit your local retailer like Home Depot, Best Buy, Walmart if you want to physically examine the product.

Honeywell HCM-350 VS the challengers

Venta LW25 Airwasher 2-in-1

Venta LW25 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 EV01 Evaporative Humidifier

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.
