Air-O-Swiss 7145 Ultrasonic Humidifier

In line with other Air-O-Swiss humidifiers, the Air-O-Swiss 7145 is an ultrasonic humidifier that provides the benefits of a hygienic cool mist humidifier in a compact, affordable package. The 7145 will effectively humidify rooms up to 600 sq. ft. with up to 3 gallons of water per day. Without sacrificing the best features Air-O-Swiss has to offer, the 7145 Ultrasonic humidifier is affordable and durable. Equipped with simple to use manual controls and a sleek, black finish, the compact 7145 Ultrasonic is ideal for nearly any room in your home.

For allergy and asthma sufferers, maintaining a comfortable and healthy humidity level is a delicate balance. When the humidity is too high mold and dust mite problems can develop. Conversely, when the humidity is too low in your home, this can lead to an array of sinus and respiratory problems. With a built in hygrostat, the Air-O-Swiss 7145 humidifier can keep your room the ideal humidity to prevent sinus problems but not worry about the proliferation of mold or dust mites.

Similar to other Air-O-Swiss humidifiers, the 7145 uses high-frequency ultrasonic vibrations to turn the water in your tank to mist that creates a comfortable environment in any room. The included Hydro Stick provides constant freshness in these humidifiers. The Hydro Stick needs to be replaced only once a year. A demineralization cartridge, which should be replaced every three months, prevents mineral residues from contaminating the water or becoming aerosolized and sprayed into the air. These three things work together to make Air-O-Swiss humidifiers safe to use.

  Dry air in Boston

We always have dry air in our one bedroom apartment during last winter. This smaller humidifer did not take up much space but we could tell a difference in our bedroom...we would recommend this to our friends.

Customer Q & A

Q1: When do you need to change the Ionic silver stick?
A: Nothing. I just snaps into the base of some models. Others, it just rests in there. That item has been discontinued though. AOS switched to a Hydro Stick then this year has switched all Ionic and Hydro sticks over to a HydroCell that is simply put into the tank of each AirOSwiss humidifier. It uses activated carbon to absorb chemicals and impurities in the water to keep the water hygienic. They come in two packs and you replace them about once every month or two, depending on usage. Hope that helps!

Q2: Does the model AOS7145 humidifier require replacement of filters and if so where do I purchase them and what is the cost?

A: The only items that need to be changed on an Air-O-Swiss 7145 Humidifier are the demineralization cartridge and ionic silver stick. The cartridge removes minerals from hard water while the ionic stick helps to kill germs in the water.

Air-O-Swiss Reviews
Air-O-Swiss 7145 Ultrasonic Humidifier

The Air-O-Swiss 7145 Ultrasonic is the more economical cousin of some of the top of the line Air-O-Swiss humidifiers. This humidifier is compact, lightweight, and comes with a black/carbon finish. Though the tank capacity is a bit less than larger models the moisture output is nearly the same, at 3 gallons, over a 25 hour period. For most homes, the size of this humidifier will be adequate to humidify several rooms with an open floor plan.

Like most Air-O-Swiss humidifiers, the 7145 has a replaceable demineralization cartridge that works to ensure a water mist without lime scale or mineral residue. The cartridge is refillable or replaceable, and basically acts as your water filter in the unit. As with all Air-O-Swiss humidifiers, do NOT use additives to the water. Even small amounts of chemical additives or fragrances can damage your unit.

What I like about the Air-O-Swiss 7145 Ultrasonic Humidifier

Aside from the hygienic features, the Air-O-Swiss 7145 is an ideal humidifier for most applications in that the compact size and modern design of this unit fits most home uses. The small footprint makes it easy to use in nearly any room, regardless of space considerations, and the moisture output rivals that of many of the top of the line Air-O-Swiss models.

The dual directional output regulator is a small but helpful feature. This allows you to split the mist stream for better coverage in all areas. The smoke/carbon colored water fill tank is transparent enough for you to note when the humidifier needs to be refilled, and this unit comes with an empty indicator light as well.

The Air-O-Swiss 7145 is very simple to use. Simply fill the tank from the bottom, replace the tank on the unit, and set the desired humidity and output level with two knobs.

What I do not like about the Air-O-Swiss 7145 Ultrasonic Humidifier

The capacity of the tank may be a drawback for some. Though the overall output is the same as larger models, the smaller tank may require you to fill it more often if you are needing a great deal of moisture pushed back into the air of your home.

Though the controls are simple to use, some people may find they like having the ability to set a time, having a digital display, or being able to use a full array of digital controls.

In all, the Air-O-Swiss 7145 is a very economical unit with uncompromising results. From moisture output and hygienic features to the modern finish and compact design, the 7145 Ultrasonic is solid room humidifier that won't break your budget.

Why buy from Customer Testimonials
My son has always had a nagging cough when the weather gets colder, that persists all winter long. The Vornado Humidifier  seems to have helped him feel better, and I don't hear nearly as many late night coughing fits. Thanks!
