The Honeywell Germ Free HCM-350 has a special sponge-like filter dipped in the water that processes the incoming air volumes. The sponge is large and water is evaporated efficiently. The device is not equipped with a humidistat and releases maximum possible humidity by default. Water naturally stops evaporating from the filter when the humidity level gets too high.

This Honeywell humidifier is extremely quiet. It is completely silent at low and medium fan speed settings. When it turned on the highest setting, there is a sound of a gentle “white noise”. The customers report that this sound helps them fall asleep quickly.

The Honeywell humidifier hcm 350 consistently provides clean moisture thanks to the combination of two highly efficient technologies. The unit is equipped with an ultraviolet light emitter that eliminates germs lurking in the water. Besides the filter is built with the use of antiseptic materials that prevent fungus growth. Nevertheless, it is necessary to clean the unit regularly and change the collector to maintain its performance.

The HCM 350 humidifier from Honeywell is 18’’ long; therefore it is larger in size than similar models. However, it is still an ergonomic device. The plastic body is shatterproof and dishwasher safe. The model is not equipped with an automatic breaker, but a transparent strip on the side of a device allows noticing when the water is low. It’s recommended to switch off the humidifier in time in order to avoid overheating.

The Honeywell hcm350 humidifier boasts very simple design in terms of user experience. There is a single knob adjusting the fan speed on the control panel. The large tank opening (3-5’’) allows to fill it hassle-free. Besides, the basin fits in any kitchen sink perfectly. The model has an ergonomic built-in handle for the water tank.

Honeywell HCM-350 Performance

The Honeywell Cool Moisture Humidifier HCM 350 brings the environment in a 150 sq. ft. room to 45% humidity in less than 35 minutes. When the tank is filled and the device is switched on, water is disinfected by the ultraviolet system. During this process germs and fungi are destroyed. Then the water is transferred to the chamber that disperses moisture to the fan.

Maintenance

The HCM 350 is a certain leader in comparison to other models in terms of cleaning convenience. The large water tank opening allows easy access to the internal parts that should be scrubbed on a regular basis. The body and most internal parts are dishwasher safe. This procedure can be used both for cleaning and disinfection every 3-4 weeks. The User Manual also recommends soaking all the details (except humidifier base) in a vinegar solution. In 15 minutes all the component will be clean. The filter should be cleaned and dried thoroughly if it has not been used for some time. Otherwise, it can get covered with mold. The sponge should be replaced at least twice a year depending on the water quality. Distilled or purified water will make filter lifespan longer.

This Honeywell humidifier boasts 3 year warranty which is above average among competitors.

Operating Cost

Honeywell 350 is a budget model. The filter costs 8$ and should be replaced every six months. The HCM-350 evaporating system is less energy efficient than ultrasonic devices. But as the test results have proven, a humidifier fan is much more effective and powerful. It moisturizes the air quicker than sonic humidifiers. In general, the lifetime cost of this model totals about 200$.
