Air-O-Swiss 7144 vs PureGuardian H4810 Ultrasonic Humidifier

As we said earlier, Ultrasonic Humidifiers are some of the quietest humidifiers that virtually give no sound, making them ideal for use while you’re sleeping. Ultrasonic humidifiers need much less electricity compared to traditional humidifiers which in turn allow you to get big savings on your electric bills. Since the mist is generated through high-frequency vibration, it will be dispersed to the room instantly after you push the “on” button.

Though both Air-O-Swiss 7144 and PureGuardian H4810 claim that they use a Silver technology to reduce the residues on the water tank thus cleaning tank becomes much easier, they both do have the cleaning issue if you use tab water. Especially for PureGuardian H4810, couple customers complaint that it could get dirty for several hours’ of usage while with Demineralization Cartridge &  EZ Cal Cleaner & Descaler included in the Air-O-Swiss 7144 Humidifiers, it helps the humidifiers stay cleaner longer. Nevertheless, to reduce the frequency of cumbersome and tough cleaning work, you’d better fill the tank with distilled water.
