Which AED brands are considered most reliable?

Several AED brands are widely recognized for reliability, safety, and long-term support. ZOLL, Philips, Defibtech, Physio-Control (now part of Stryker), and Cardiac Science are among the most trusted in both public and workplace settings. These manufacturers offer FDA-approved and Health Canada–approved models, ensuring compliance with local regulations and quality standards. They have established reputations for durable, easy-to-use devices, effective voice prompts, clear visual instructions, and consistent performance during emergencies. Additionally, these brands provide reliable manufacturer support, maintenance programs, and replacement pads and batteries, which are critical for keeping devices operational over time. Choosing a reputable brand not only improves the likelihood that your AED will function correctly in a cardiac event but also gives your organization peace of mind that the device is backed by decades of clinical experience and proven performance.
