Best AEDs of 2026: Compare ZOLL, Philips, LIFEPAK, Defibtech, HeartSine & Cardiac Science
There is no single “best” AED—there's the best AED for your setting. Every model sold in the U.S. is FDA-approved and effective at treating sudden cardiac arrest, so the right choice comes down to who will use it, where it will live, and how much hands-on guidance your rescuers need. Below we compare the six leading AED brands and pick the strongest option for homes, businesses, schools, places of worship, and first responders.
How to choose an AED: what actually matters
- Ease of use: Clear voice prompts and a simple, foolproof interface for untrained bystanders.
- CPR feedback: Real-time coaching on compression rate and depth measurably improves CPR quality.
- Semi- vs. fully-automatic: Semi-auto prompts the rescuer to press “shock”; fully-auto delivers it automatically after warning. Both are equally effective.
- Durability (IP rating): Higher ingress protection matters for outdoor, industrial, sports, and field use.
- Pediatric capability: A pediatric key, mode, or child pads for sites that serve children.
- Total cost of ownership: Battery and pad replacement cycles drive long-term cost as much as the purchase price.
- Warranty & connectivity: Longer warranties and network/cellular readiness checks simplify program management.

Frequently asked questions
What is the easiest AED to use?
Philips HeartStart and Defibtech's video-guided VIEW are frequently cited as the most approachable for untrained bystanders, but every modern AED is designed for laypeople with clear voice prompts.
Should I get a semi-automatic or fully-automatic AED?
Both are equally effective. Fully-automatic delivers the shock automatically after a warning (no button press), which some find less intimidating; semi-automatic keeps the rescuer in control of the final step.
Which AED is best for CPR coaching?
ZOLL's Real CPR Help and the LIFEPAK CR2 are standouts for real-time compression feedback, with Cardiac Science and HeartSine's 450P also offering CPR guidance.
