Both manufacturers and authorized third-party distributors are valid sources for purchasing AEDs, but each has advantages depending on your organization’s needs. Manufacturers typically guarantee the latest device models, full warranties, and direct support, which can be reassuring for organizations that prioritize manufacturer-backed service. Authorized distributors, on the other hand, often offer more competitive pricing, bundled services such as staff training or maintenance plans, and faster delivery—especially when purchasing multiple units for several locations. When choosing a third-party distributor, it is crucial to confirm that they are officially authorized by the AED manufacturer, and that the units they sell come with valid warranties and manufacturer support. Working with an authorized distributor can provide cost savings and convenience while ensuring compliance and device reliability, whereas purchasing directly from the manufacturer may offer a more direct line of support and guaranteed access to the newest models.
