Works great with my home oxygen compressor. A warning to those with allergies or asthma. When I was recently in the hospital the respiratory therapist added some kind of powder to the oxygen humidifier to make the water softer, & I had such a burning in my nose and throat that they had to take me off the oxygen until they could figure out why I was having such an allergic reaction or sensitivity. My advice is not to use any chemicals in this humidifier, & to simply use tap water or bottled water. Then it works perfectly well.
