Effectiveness and Output

The Vicks V790 UV Germ-Free Humidifier has two tanks which can be filled up and produce an output of up to two gallons of water within a twenty-four hour period. Because of this, the product can be used for a full day without having to turn it off. Because of the two tanks, refills can be made alternately without having to turn the machine off, and this contributes to the convenience of using the product for long periods of time. Existing users were able to use the machine even in a room that is as large as 400 square feet without having any problems. Thus, it can be used in any room in the house, big or small.


The Vicks V790 UV Germ-Free Humidifier has three LED indicators. The first one is the power indicator. The second LED is used to signal the user when itís time to replace the UV bulb. The third one is used to signal a need to refill water. The LEDs are so bright that it can be a little distracting during the night. Some users see this in a positive manner and use the LED indicator as an alternative to having a night light. For those who love to sleep in utter darkness, covering the LED with some electrical tape might do the trick.

The Vicks V790 UV Germ-Free Humidifier also comes with a medicine cup. One can use Vicks Vaposteam or other brands of inhalants and put some on the medicine cup in order to produce a therapeutic mist that can help someone who is having breathing difficulties because of colds. It can also help soothe someone who is having a sore throat or dry cough. Thus, the machine can do more than just cure dry air.

The UV Bulb is installed in order to kill 99.99% of the germs and bacteria in the humidifier. This is to ensure that the mist being produced from the humidifier and being inhaled by everyone in the room or house is safe and germ-free. After all, no one wants to breathe moist air that is full of bacteria and germs that can lead to worse problems than what dry air can give to a person.

Pleasant Noise

On the first few days of using the Vicks V790 UV Germ-Free Humidifier, the noise levels might be a bit irritating. However, as the machine leaves its break-in period, the noise levels change and become more tolerable. The sound produced by the machine is comparable to the sound produced by boiling or gurgling water, without the noise produced by running motors. Rather than being irritating or annoying, the sound contributes to the overall ability of the machine to induce a soothing and relaxing feeling to everyone in the room.

Cleaning and Maintenance

The Vicks V790 UV Germ-Free Humidifier does not have any filter, so users do not have to worry about buying expensive filter replacements on a regular basis. Aside from regular cleaning, however, there are two other things that users need to be aware of when it comes to the maintenance of this product.

The first one involves mineral pads. Mist humidifiers such as this one do not release mineral dust; the dust is kept in the hot water reservoir. The mineral pads absorb these in order to keep the water and mist clean and safe. In areas where the water is moderately hard, mineral pads can last up to 3 weeks. In areas where the water is extremely hard, the padís life may be shorter. If the pad is very stiff and hard or it starts to disintegrate, which happens when softened water is used, then itís time to replace the pads. The use of mineral pads is optional; however, not using pads would result in more frequent cleaning being needed.

Users would also have to replace the UV bulb from time to time. There is no specific period of time as to when the bulb needs to be replaced. This should not be a worry, though, because of the LED indicator that lights up when replacement is necessary. It is also important to note that since the UV bulb is an added feature to kill germs and bacteria, the humidifier may still be used even if the replacement bulb has not yet been installed. During this time, however, the ability of the machine to kill bacteria and germs is reduced.

Vicks V790

Visual Design

The Vicks V790 UV Germ-Free Humidifier looks like most mist humidifiers that are currently in the market. It has a functional design, which makes it very simple and easy to operate. The medicine cup is located comfortably on top of the machine in order to provide additional ease in putting or replacing inhalants as the need arises.


The Vicks V790 UV Germ-Free Humidifier has a size of 16.9 inches by 12.3 inches by 13.6 inches. The machine weighs about 10.4 pounds. Therefore, it would be easy to move it around the house and put it in the room or area where it is most needed at a particular time. Given its small size, it can be used even for childrenís rooms and it would take no more than a square foot.


The Vicks V790 UV Germ-Free Humidifier has two individual tanks that can hold up to two gallons. This amount of water can produce mist and humidify an area for up to 24 hours. This amount may vary depending on the humidity level selected by the user. If the machine is set to the highest level, the full tank capacity of the machine may not reach 24 hours. With a moderate or low humidity setting however, filling both tanks may be enough for a night or two of comfortable sleep.

Value for Money

The Vicks V790 UV Germ-Free Humidifier may not be the cheapest humidifier available at the moment. However, this product is very reasonably priced especially when we consider all the other benefits that one can get from this machine. The price is also compensated by the fact that the product does not require the use of filters. Some brands may cost half as much as the Vicks V790 UV Germ-Free Humidifier, but requires a filter replacement once every couple of months. Aside from the mineral pads and the UV bulb, which are both not required for the machine to operate, there are no other items that need constant replacement.

Suggested Accessories

The main advantage you get when you choose the Vicks V790 over other models or brands is the option of using the unit not just as a simple humidifier, but also for the purpose of inhalants. Just like the Vicks V745A, this particular model offers a medicine cup that turns the machine into a healing machine for coughs, colds and clogged noses. To do this, you must buy an additional accessory: humidifier or dehumidifier inhalant liquid medication. Vicks Vaposteam cough suppressant as well as Kaz inhalant are bestsellers and can be used on the Vicks V790 model.

Such medications are strictly not for oral use as they must only be used by placing them on the humidifierís medicine cup. This is done so when the mist is released by the humidifier, the steamed medication can help relieve clogged noses or help suppress coughs and colds.

Such accessories are very useful for those who easily catch colds especially for kids and teenagers whose health are easily affected by changes in weather.
