ResMed H4i™ Heated Humidifier

See Details
If you are purchasing a new CPAP, Auto CPAP or BiLevel (BiPAP) machine, humidifier or an oxygen concentrator, then federal law requires that we receive a copy of a prescription written by your doctor. A sleep study report does not qualify as a prescription.  Also, the purchase of complete CPAP masks does require a prescription.  (*** Note that the component parts that make up the mask DO NOT require a prescription! ***)
The prescription must state that it is for CPAP therapy and at what pressure your machine should be set. If you are purchasing a standard CPAP machine (one that operates at a constant pressure), then the prescription must show one pressure setting, which is generally a number between 4 and 20 and measured in cm of H2O. If you are purchasing an Auto CPAP machine, then your prescription must state two different pressures: A low (minimum) pressure setting and a high (maximum) pressure setting. If you are purchasing a BiLevel machine, then your prescription must state two pressure settings: An inspiratory (IPAP) setting and an expiratory (EPAP) setting.  If you are purchasing an Oxygen Concentrator, the prescription should have the flow rate stated in Liters per minute. 
Prescriptions can be faxed to us at 888-469-2555, or we can accept a scanned copy of your prescription by emailing it to us at [email protected].

Please note that orders for machines, concentrators, or complete masks will NOT be shipped until we receive a copy of your prescription!
