How to Counteract Dry Winter Air

During the cold months of winter, my furnace does a great job keeping me warm. Unfortunately, it also pulls plenty of water from the air. As the humidity drops, my skin dries out, and painful cracks appear on the tips of my fingers. Air conditioners are just as culpable, because as they cool the air, they remove its moisture.

Humidity is best kept between 30 and 60 percent, with the most comfortable range being 45 to 55 percent. High humidity increases the risk of mold forming. 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.

There are several ways to combat low humidity. Today I am reviewing a device that produces a steady stream of water vapor by subjecting a tank of water to ultrasonic vibrations.


The Kyvol Vigoair HD3 Humidifier, when empty, weighs in at 3.5 pounds. This device is 14.7 inches tall, 8.2 inches wide, and 6.6 inches deep.

This humidifier, housed within a white plastic case, consists of two main units. Power is routed to the base, which contains the ultrasonic device (atomizer), control panel, air vent, and water reservoir. An air inlet protected by a foam filter is located at the bottom of this unit. The primary purpose of the base assembly is to atomize water, converting it into a cool mist.

The water tank sits directly above the base. It is topped by a removable directional nozzle that covers the mist emitter and upper carrying handle.

The bottom of the tank includes an opening into which water can be poured. This opening, secured by a cap, allows water to be released when the tank is fully inserted into its base. Also located here are a second carrying handle and an outlet used to direct atomized water upward.

This humidifier accommodates up to 1.18 gallons of water. When filled, the device will operate, depending upon the setting, between 13 and 75 hours. Even at the highest setting, this device is very quiet.

How to Set Up and Use

  1. Position the base within the room you wish to humidify.
  2. Remove the tank's nozzle to access the upper carrying handle and unscrew the cap located at the tank's bottom.
  3. Fill the tank with cold water, screw the cap back on, carefully sit the tank atop its base, and replace the nozzle.
  4. Connect the device to AC power. Use the dial to turn on the unit and control how much moisture is released into the air.

Cool Mist Levels

  • Minimum: At this setting, I could feel a cool breeze emitting from the humidifier's nozzle. According to Kyvol, operating time at this setting is approximately 75 hours.
  • Medium: A distinct funnel of whitish water vapor is produced at the medium setting. During my tests with a full tank, the Kyvol humidifier operated for 29.5 hours before automatically shutting down as it ran low on water.
  • Maximum: At this setting, a dense cloud of water vapor spirals from the top of the humidifier and spreads throughout the room. During my tests in this setting, the humidifier operated continuously for 14.6 hours.


I moved the Kyvol Vigoair HD3 humidifier into my kitchen and set it at its maximum level. Within 2.5 hours, the room's humidity has risen from 33% to 43%. At this point, I could have reduced the humidifier's output to a point where the humidity remained at a constant level.

My kitchen is 12 x 14 feet in size and opens into a similarly-sized dining room. A large archway connects my dining room to the living room. While my kitchen's humidity jumped ten percent during the original test period, it rose only two percent in the living room. As the day progressed, it continued to rise slowly.

The Kyvol Vigoair HD3 does a great job adding moisture to a single room. However, it is not intended to humidify an entire house.


Any device that works with water must be cleaned every week.

Scale removal consists of emptying the humidifier and then filling its tank halfway. Add one teaspoon of white vinegar, screw in the cap, and shake the tank for 15 seconds. Then place the tank atop its base. After waiting 20 minutes, empty the humidifier.

To disinfect this device, empty it and then fill its tank halfway. Add ½ teaspoon of bleach, replace the cap, and shake the tank for 15 seconds. Then place the tank atop its base and allow this solution to clean the entire system for 20 minutes. At this point, you can drain the humidifier, fill it with water, and put your device back into service.

Overall Impression

While not intended to humidify an entire house, this device can quickly increase the air circulating's water content within a single room. It is quiet, relatively easy to maintain, and its tank can be refilled quickly when required. If you are searching for a quality humidifier that comes without a huge price tag, the Kyvol Vigoair HD3 is worth a close look.
