Description of Air O Swiss S450 Steam Humidifier

The Air O Swiss S450 steam humidifier has been designed utilizing a blend of traditional vaporizer technology with high quality materials, modern design and state of the art user controls. The AOS S450 humidifier offers variable mist settings and a built-in hygrometer that monitors the room’s humidity level in order to provide the perfect amount of healthy, warm moisture. The warm mist output is both safe to the touch and is healthy to breathe. The Air O Swiss S450 steam humidifier internally heats the water to 212 degrees, completely destroying bacteria and other organic contaminants. The AOS S450 comes with two Anti-Mineral-Pads to decreases the calcification in the vaporizer basin and a packet of EZCal formula to assist with cleaning. The AOS S450 has a daily moisture output of up to 3.5 gallons and will humidify a space up to 860 square feet.

Care of:


The Anti-Mineral Pad absorbs a large part of the resulting lime scale while in operation. The Anti-Mineral Pad reduces excessive calcification of the steam tray as well as the frequency of necessary decalcification. In order to insert the Anti-Mineral Pad, remove the top cover, water tank and steam pipe from the unit. Now insert the supplied Anti-Mineral Pad directly into the steam tray and reassemble in reverse order. The Anti-Mineral Pad needs to be replaced as soon as it is completely full of lime. Depending on the hardness of the water, this needs to be done every 2 to 4 weeks. The Anti-Mineral Pad can be disposed with your household waste.

The Anti-Mineral Pad needs to be removed before starting the self-cleaning Decalcification Mode. Simply dissolve the included EZCal cleaning agent into 32 oz. of warm water and pour directly into the base of the S450. Then reinsert the steam pipe and top cover. Press and hold button (A) for 5 seconds to switch the humidifier to Decalcification Mode. Button (C) can be used to change the decalcification period from 1 to 9 hours depending on the level of soiling on the steam tray.

This Air-O-Swiss S450 operates like a traditional vaporizer but is designed with today's advanced technology and high-quality materials to ensure it will last for many years. This steam humidifier produces a bacteria and mineral-free, warm mist output that is safe to the touch and will not cause a burn. The AOS S450 will humidify a large space and offers very quiet operation, ideal for use in any room.

Pluses:

  • Boiling the water kills bacteria, microbes and breaks down minerals, which creates a warm steam output that is safe, healthy and free of white dust.
  • Humidifies a very large area.
  • Traditional vaporizer technology is hygienic and healthy.
  • Maintenance is simple and minimal thanks to the Decalcification Mode setting.
  • Digital controls are easily programmed and complete with automatic shut off and tank empty indicator.
  • Easy to carry and fill water tank.
  • Quality construction for years of operation
  • Internal humidistat allows for humidity levels to be set at 30%-70%.
  • Backed by a 3 year warranty.

Minuses:

  • Operation is not silent and thus this may not be an appropriate solution for those who are very sound sensitive.

Summary:

The Air O Swiss S450 is a remarkable humidifying gem, fusing traditional vaporizer technology with modern state of the art construction, materials and user controls. While the S450 humidifier is not as silent as its ultrasonic rivals, it does remain very quiet and fine for a bedroom. We like that the boiler technology eliminates virtually all bacteria and impurities that often concern humidifier owners. The self cleaning Decalcification-Mode makes cleaning a breeze and is unique to the Air O Swiss S450. This is a simple and straight forward humidifier design that will be very appealing for those who are not fans of ultrasonic humidifiers.
