Air-O-Swiss 7135 Ultrasonic Humidifier Customer Q & A

Air-O-Swiss 7135 Ultrasonic Humidifier Product Details
Q1: Does this have any parts that needs to be replaced and how often?

A: There are two replacement parts - the demineralization cartridge and Hydro stick. The Hydro stick is generally replaced annually, and works to keep the water free of bacteria, germs, etc. The Demineralization cartridge needs to be replaced every 2 weeks to 3 months. This all depends on how hard your water is. If you notice any fine white dust, it's time to replace the cartridge. This is the mineral content in your water, not being removed and being dispersed by the humidifier. To avoid this entirely, you can use distilled water and remove the cartridge altogether.

Q2: What's sleep mode on the more expensive model?

A: The Sleep mode in the digital Air-O-Swiss humidifiers models functions like this. When you select it, the humidity automatically targets 50-65% the timer is set to 6 hours the preheat function kicks on, and the display dims. After six hours, it will shut off.

Q3: Does this have medicine cup, can you use essential oils with this product and does it purify?

A: Neither the AOS 7135 nor the AOS 7133 humidifier has a medicine cup. You should not put anything other than water in the tank as it could possible damage the diaphragm or internal components of the humidifier that nebulize the water. The demineralization cartridge traps hard water minerals like magnesium and calcium but does not "purify" the water as carbon/charcoal based filters do.
