The Elechomes' SH8830 Cool and Warm Mist humidifier

The Elechomes' SH8830 Cool and Warm Mist humidifier

My air conditioner is great at keeping me comforatble during the summer. Unfortunately, the process of cooling the air involves removing much of its moisture. As the humidity drops, my skin begins to dry, and painful cracks appear on the tips of my fingers.

The situation worsens in the winter. Each time my forced air furnace kicks in, it draws air from the room, heating it and evaporating away its moisture.

Humidity is best kept between 40 and 60 percent, with the most comfortable range between 45 and 55 percent. Low humidity dries out your skin, your eyes, and the mucous membrane lining your respiratory tract. Aside from the obvious discomfort, overly dry air increases the risk of colds, flu, and other infections. High humidity increases the risk of mold forming within your house.

Last year I reviewed a device that produces a steady stream of mist by subjecting its water input to ultrasonic vibrations. While filling its water tank every day was a bit of a pain, this humidifier managed to keep the air within my kitchen relatively moist.

Today I am taking a close look at a slightly larger and much more sophisticated device that is intended to humify my entire house.

Description

My new Elechomes SH8830 Humidifier measures 11 inches in width and 7.5 inches in depth at its base, slightly tapering as it rises. This device is 13.4 inches tall. Its case is composed of either black or white plastic.

The base of the SH8830 includes a steam head, atomizing plate, float ball, anti-scale plate, PTC heater, control panel, and an aromatherapy compartment. The primary purpose of this assembly is to atomize water, converting it into a cool mist. It can also produce a warm mist by heating the water.

This humidifier's 1.7-gallon tank includes a water filling nozzle, mist outlet, and an outlet valve. It is covered by a plastic plate fitted with a headcover that controls the emitted mist's direction. The tank's large capacity allows it to operate for up to 72 hours.

An input of 120VAC is required to operate this device.

Theory of Operation

The Elechomes SH8830 utilizes two different methods to add moisture to the air.

When Cool Mist is selected, ultrasonic vibrations create a micro-fine cool mist that is quietly released throughout your environment. A fan is used to disperse this mist. The maximum dispersal of water utilizing this mode is 300mL/h.

If Warm Mist is selected by pressing the heating button, an internal heating element boils water before releasing it as a soothing mist throughout your house. Because this mode works in conjunction with the Cool Mist mode, up to 700mL/h of water can be dispersed.

The Control Panel

The display indicates the current temperature and humidity. It also offers feedback, displaying the various selected settings.

Both the control panel and the remote are fitted with eight buttons. These are used to turn on the device, select the desired humidity, choose the mist level, and operate the heater. You can also select auto mode, initiate a timer, turn off the display, and enter child lock mode.

The 60 Percent Cool Mist Test

My first day of testing proved to be very cold, with an outside temperature ranging between 28-46 degrees Fahrenheit. I selected a high target humidity of 60 percent and ran the SH8830 at its maximum cool mist level.

The humidifier constantly ran because the furnace would kick in each time the humidity approached its target range, heating the air and sucking out its moisture. Over one day, the humidifier ran its tank dry.

The 60 Percent Warm Mist Test

The next day proved to be even colder. I set my target humidity to 60 percent and selected the highest levels of warm and cool mists. In this mode, the SH8830 significantly increased the amount of moisture it dispersed in the air. While the humidifier provided a reasonably stable humidity level of 60 percent, I did have to keep a cautious eye on its water tank to ensure it did not run dry.

The 55 Percent Cool Mist Test

The following day was warmer, with a temperature range of 36-59 degrees. I set my target humidity to a more reasonable 55 percent. This time the SH8830 was able to bring the house's humidity up to the target level well before the temperature dropped enough to turn on the furnace. During this 24-hour test, I used a half tank of water.

The 50 Percent Cool Mist Test

Another frigid day greeted my third test. I set my target humidity to a comfortable 50 percent. The furnace came on quite often, dropping the humidity to about 43 percent. The SH8830, however, thanks to its more modest target range, was quickly able to cope. Over 24 hours, the device drained one-third of the water from its tank.

Normal Usage

At present, I plan to set the target humidity at 50 percent. Then, as the temperature drops—Eastern Canada contends with sub-zero temperatures in the winter—I will probably be required to switch to warm mist and experiment with the three different settings available in that mode.

Next summer, after I turn on the air conditioners, I will have to deal with dry air again. I suspect the cool mist mode will prove adequate in the hotter weather.

Overall Impression

I like this device. You fill it with water, turn it on, and set the desired humidity target. Then it quietly keeps the humidity of your house at a comfortable level. You can even add a couple of drops of aromatic oil if you'd like.

While reasonably sized, this humidifier comes with a large 1.7-gallon tank and includes an easy-to-read display. The Elechomes SH8830 Humidifier is strongly recommended.
