Philips HeartStart HS1 AED

The Philips HeartStart HS1, often referred to as the Home Defibrillator, is a world-renowned Automated External Defibrillator (AED) developed by the healthcare technology giant Philips. Originally developed under the Heartstream acquisition, the brand flourished as Philips became a global leader in cardiac resuscitation technology.

Manufacturing of these units and their specific electrode pads primarily occurs in technical facilities in the United States (Washington state) and the Philippines. As of 2026 and beyond, the brand remains under the ultimate ownership of Royal Philips, headquartered in the Netherlands, which oversees its global distribution and medical compliance.
