Dry air can cause some health issues such as sore throat, dry skin, cough, and difficulty in breathing. Through the help of humidifiers, dry air can be addressed and the health issues can be prevented. With so many brands and types of humidifiers to choose from, it can be very difficult to determine which one is the best choice.

After checking out several brands and models, the Air-O-Swiss AOS 7144 Ultrasonic Humidifier is one of those that stood out. Here are some of the reasons why it would be a good investment to go for this one.

Powerful Output and Wide Coverage

The Air-O-Swiss AOS 7144 Ultrasonic Humidifier has a maximum output of 3.5 gallons within a 24-hour period. It is powerful enough to humidify a room that has an area of 650 square feet. Thus, for a standard sized room, the maximum water supply can last for even more than a day or two full nights of comfortable sleep.

Technologically Advanced

The Air-O-Swiss AOS 7144 Ultrasonic Humidifier has numerous features that make it state-of-the-art. The LCD display shows the current humidity level in a particular room. It works hand in hand with the trademark Air-O-Swiss Intelligent Temperature Compensation or ITC Technology, in order to monitor the temperature and humidity level in a room and make sure that the output levels adjust accordingly as the conditions change.

This is perfect for people who would like to do everything simply and easily. The AOS 7144 has a pre-set timer so that when the user turns it on, it can be programmed to be turned off at a particular time, without the user having to get up from bed just to turn the machine off. In addition, it also has an auto-power off function that works when the ideal humidity level is reached or when the water supply is fully consumed.

The tank is equipped with a demineralization cartridge and a Hydro stick which filters the water and keeps the tank free from bacteria, germs, and molds. There is also an indicator light that will signal the user when it is time to clean the machine or replace the filter.

Negligible Noise, Softer than a Whisper

The sound of a whisper is estimated to be at 30 decibels. The Air-O-Swiss AOS 7144 Ultrasonic Humidifier has a sound of less than 25 decibels. Thus, users will not hear anything from it unless there is utter silence in the room. Because of this, it is ideal to use the machine even for a baby’s nursery or a kid’s room. Anyone can have a nice and sound sleep and not be bothered by humming or gurgling sounds from the humidifier.

Simple Cleaning and Maintenance Requirement

Traditional humidifiers need to be cleaned regularly. Filters or mineral pads need to be replaced frequently in order to remove any mineral deposits and residues. Some humidifiers require weekly cleaning. For people leading busy lives, this is utterly unacceptable. The Air-O-Swiss AOS 7144 Ultrasonic Humidifier uses a demineralization cartridge that needs to be replaced only twice a year and a hydro stick that needs to be replaced annually. In addition, there is a light indicator that sends signals once the user needs to clean the machine, and this does not light up very often.

Outstanding Design and Overall Look

The Air-O-Swiss AOS 7144 Ultrasonic Humidifier exudes sophistication and class with its LCD display, silver finish, and compact design. It veers away from the traditional colors used for humidifiers, making it stand out in terms of visual elegance and style. Even with this sleek design, the machine’s efficiency and power is not compromised.

Lightweight and Does Not Take Up Much Space

The Air-O-Swiss AOS 7144 is 10 inches long, 11.4 inches wide, and 13.7 inches high. Thus, it is just a bit smaller compared to other humidifiers that are within the same output level. However, it only weighs about 9 pounds. Because of this, it is very easy to carry it anywhere around the house where it is most needed.


Because of its compact size, the Air-O-Swiss AOS 7144 can only hold a small amount of water. Although the maximum output for the machine is 3.5 gallons for 24 hours, this does not necessarily mean that the tank can hold up to 3.5 gallons of water at one time. If someone would like to max out this amount of mist output for a full day, the tank has to be refilled for two or three times within the said period. This is a good compromise to keep the machine small and stylish, especially because the machine does not always have to be emitting the maximum amount of mist. In addition, the need to keep the machine running for 24 hours straight is very rare that filling the tank just enough for it to run for 8 to 12 hours is good enough.

Refilling the tank though can be a bit time-consuming. The demineralization cartridge needs to be unscrewed first and the tank turned upside down before it can be refilled. Thus, you have to allow some time for refilling the water and putting everything back in its proper place.

Value for Money

One can find a non-digital ultrasonic humidifier that only costs about a third of how much the Air-O-Swiss AOS 7144 currently costs in the market. In the long run, however, it is often a more practical option to invest on a high-priced humidifier than to buy an inexpensive one. Why? First, cheap humidifiers cannot be programmed to vary the settings depending on the room’s condition. Thus, it will continue to run and consume electricity even when the room is already humid enough.

In addition, cheap humidifiers do not usually come with a humidity gauge. Thus, one would have to buy this separately in order to effectively monitor the humidity in a room or house. Because of this machine’s pre-set timer and auto-power off function, the machine will only run as needed and it is highly possible that it will not run and consume electricity for a full 8 hours while one is asleep.

Recommended Accessories

The Air-O-Swiss AOS humidifier already has a built in hygrometer thus it is not necessary that you buy a separate one. What we would suggest is that you stock up on a few cleaner and descaler just like the EZ Cal from the same brand. This accessory provides additional anti-microbial protection. In simple terms, this accessory can help prevent as well as control microbial growth in your unit. The cleaner and descaler offered by Air-O-Swiss can work well with both warm and cool humidifiers. By using this product, the water you put into your unit’s tank will be cleaner even as it also protects your unit so its life is prolonged.
