Most AED buyers spend hours researching across multiple brand websites before purchasing (typical pattern reported by authorized distributors). That research ends roughly where it could have ended in 60 seconds: with the right brand for the buyer’s profile. This article exists to end the loop. Seven brands ship FDA-approved AEDs in the US, and they split four ways by buyer profile.
The framework: identify your buyer profile, match it to one brand, verify with the brand-specific deep-dive review.

4-question decision tree to end the brand-comparison loop
Question 1, How many AEDs are you buying?
1 unit → continue to Q2. 2–4 units → continue to Q2 (volume math is the same as for a single unit). 5+ units across separate locations → LIFEPAK CR2 (cellular fleet management math wins). Run the AED Quantity Calculator to verify the unit count.
Question 2, Indoor or outdoor primary deployment?
Indoor only → continue to Q3. Outdoor/sustained weather/pool deck → HeartSine 450P (IP56 only mainstream option). See IP Ratings Explained.
Question 3, Will rescuers be CPR-certified?
Yes, certified staff → ZOLL AED Plus (depth feedback ROI clear). No, untrained bystanders → continue to Q4. CPR training resources: CPR + AED Together.
Question 4, What’s your budget cap?
Under $1,400 (5-yr total) → HeartSine 350P or Defibtech Lifeline. $1,400–$2,500 (5-yr total) → Philips FRx for K-12 / daycare, Cardiac Science G5 for workplace without inspection routine. Over $2,500 (5-yr total) → reassess unit count (cellular only worth it at 5+).
Where to buy any of these brands safely
Always purchase through authorized US distributors – AED Leader, Response Ready, or directly through manufacturer-authorized channels. Gray-market AEDs sourced from third-party marketplaces or international wholesalers may void the warranty, miss FDA recall notifications (see Recall Tracker), and complicate Good Samaritan owner protection (see Good Samaritan AED Laws).
