Humidifying the air helps you and your family breathe easier, especially when congested, but moistening dry air, especially in winter when heating units can make your house particularly dry, helps your nasal passages even when you don’t have a cold, allergies, or flu. Moist air is also better for your skin and complexion. Don’t be surprised when you start to get compliments on your skin when you start regularly humidifying the air in your home.
The unit holds just over a gallon and has an output of 3.5 gallons. It has dual, rotating outlets to evenly distribute moisture in the air. There is a digital humidistat that allows you to choose humidity between 40% and 75%. The humidifier has some advance technology that Air-O-Swiss calls “Intelligent Temperature Compensation” that automatically adjusts the humidity based on the temperature in your room. There is also a sleep mode that automatically determines a comfortable humidity level for sleeping. Another nice feature on this unit is the timer which will allow you to sue the unit for anywhere from one to eight hours of continuous operation. There is a digital display, making this unit look as high tech as it obviously is.
A demineralization cartridge is included which removes lime and minerals. If you do not use this cartridge and discover white dust near your humidifier, it means that your water has minerals and you should either use the demineralization cartridge or use filtered or distilled water.
There is an optional “Hydro Cell” that can sit in the water tank that helps keep the water fresh. It is essentially an activated carbon filter to catch impurities. Also optional is the descaler product that can be used for cleaning. Cleaning is recommended every 2 weeks or so, A distilled vinegar and water solution can be used instead of the descaler product, but some users prefer the descaler rather than experiencing a vinegar odor.
