Just what was needed
The product works great, it fit the oxygen concentrator perfectly and gives moisture to the oxygen so that your nasal passages don't dry out as much.<br /><br />I use distilled water so that mineral deposits aren't made and breathed in or mess with the function of the machine.<br /><br />You unscrew the top off, add distilled water, screw the lid back on.<br />Then you twist on the top small bolt with wings onto the oxygen device and make sure its secure, this will hold the bottle in place.<br />After that attach the tubing to the cone shaped hole on the side of the lid.<br /><br />Oxygen will come in through the top of the cup, down the straw creating a Jacuzzi effect and air leaves the cup through the lid, side cone shaped hole.<br /><br />Hope this helps
