Honeywell Germ Free Cool Mist Humidifier HCM-350 Review

Cold season is still in full effect and the combination of winter’s dry air, closed windows and a turned up thermostat can cause havoc on your respiratory system. The best way to fight dry air and rescue your vulnerability to infection is to invest in a humidifier. Humidifiers work to put moisture back in the air. There are a number of humidifiers in the market but one of my personal favorite and also for the second year running has been ranked s the best humidifier is the Honeywell Germ-Free Cool Mist Humidifier HCM-350.

Ease of use

Most reviewers have reported that this humidifier is easy to use. There is only one dial to set fan speed and efficient. The water tank has a wide mouth which makes it easy to fill and it also has a strong built in handle which makes carrying tank easy.

 Kills 99% of germs in water

This is one of the selling points of this humidifier. It is capable of killing up to 99% of the bacteria in the water together with spores and the mold found in the water in order to produce a clean healthy mist.

 QuiteCare Technology

The humidifier is very quiet. In fact on low and medium speed, it is practically silent. If you put it on and place it on high speed and next to your bed when you are going to sleep, you may hear the sound of the fan running quietly. The sound that the fan produces is still soothing and may actually help you sleep more.

 Built in antimicrobial treated filter

This helps to improve the quality of the air output. The automatic moisture balance system is also great for maintaining the air temperature of the room


The untreated water flows from the water tank directly into the UV water path then it is exposed to UV light which kills the viruses, fungus bacteria, and any mold present. The sanitized water then moves into to the base where it is going to be absorbed by wicking filter. The dry air in the room is sucked through the filter that absorbs moisture and the germs-free air is then introduced into the air as the fine invisible mist. Humidifies areas of up to 500sq feet and uses 1.5-gallon tank capacity which lasts for up to 24 hours per filling.
