AED Buying Guide: What are the Best Defibrillators in 2024

The Best AED Products in 2024

We get asked about the ‘best AED’ all the time. This question is hard to answer because depending on your location and needs the best fit for you can vary. The AED’s we recommend most often are the Heartsine Samaritan AED and the ZOLL AED plus. However, these are just a two options and there are a lot more we recommend. Read below to gain full understanding on what AED’s are, how they can be used, and what special features you may want to look for to meet your specific needs.

Why are AEDs so Important?

What are AEDs

An AED, also referred to as an Automated External Defibrillator, is a potentially lifesaving medical device that, over the years, has grown more and more popular in a variety of offices and other work environments, along with CPR and AED training, to help adults and children who are experiencing cardiac arrest.

What are AEDs used for?

This particular medical device is used in cases where someone is experiencing cardiac arrest. The purpose of an AED is to analyze the rhythm of a person’s heart effectively and, if it’s irregular, deliver an electrical shock through pads placed on the victim’s chest that’ll help return the rhythm to its stable and normal rhythm.

AED’s are incredibly cost-effective life saving solutions, and given the role that AEDs play, there’s no doubt that they’re essential to have in absolutely every single public building. Cardiac arrest can strike at any time without warning and can affect even those who are young and seemingly physically fit.

AEDs are Safe and Reliable

AEDs only shock an irregular rhythm called Ventricular Fibrillation. Therefore, it cannot and will not shock a normal heart beat. This makes it an incredibly safe device to be used in the case of emergency.

Cardiac arrest is defined as irregularity or termination of a person’s heartbeat, however, unlike a heart attack, it is an electrical problem that creates abnormal heart beats, preventing the heart from pumping blood to the rest of the organs. Given the severity of this problem, time is of the absolute essence, and this is where AEDs come in handy to provide potentially life-saving care.

It has been shown that every minute the use of an AED is delayed, the probability of survival decreases by 7-10 percent. If AEDs are used alongside CPR, then the probability of survival increases up by up to 75%.  If AEDs are not used at all, the chances of surviving a cardiac arrest is less than 5%. According to the National Safety Council it has been shown that increased access to AEDs could save as many as 40,000 lives each year.

All these figures show the necessity and reliability of these life-saving devices. Given the high stakes of situations that require the use of AEDs, there are safety measures taken by the government that ensure that every AED device meets a specifically defined criteria to ensure their safety and reliability. The FDA has also issued a list of approved AED devices and require companies who sell AED devices to get federal clearance.

Growing Market and Demand for AEDs

Cardiac arrest can happen to anyone, even young athletes. It’s the leading cause of death in people over the age of 40. As mentioned above, the use of AEDs at a critical moment can mean the difference between life and death, so given the uncertainty of cardiac arrests and high efficacy of these devices, the demand for AEDs is rising and there is a huge need and market for these products. According to an estimate, the global market for AEDs is predicted to rise to $4.47 billion in 2025, from $1.21 billion in 2016. The market for AEDs is predicted to set a compound annual growth rate (CAGR) of approximately 15.8 percent.

AEDs in the workplace

Lately, there has been a consistent increasing trend in workplace induced stress, and stress is known to be one of the greatest causes of cardiac arrests. This means that there is a dire need of AEDs in the workplace. Although occupational health and safety rules and regulations do not require a defibrillator in the workplace, Occupational Safety and Health Administration (OSHA) recommends having the device readily available on job sites.  Many workplaces have already started offering training programs on the use of AEDs in emergency situations which has increased the demand for these devices considerably.

OSHA has specified the following guidelines for the availability and use of AEDs in the workplace:

  1. Designate employees that are authorized to use defibrillators in emergency situations
  2. Train employees on proper use of AEDs, including manufacturer’s guidelines.
  3. Place AEDs in areas where they can be accessed within 3 to 5 minutes of a cardiac arrest
  4. Make sure that in-office AEDs are inspected, tested, and maintained as noted in the manufacturer’s specifications.

What to Look for in AEDs?

AEDs have evolved over time from their design and user functionality. There is a wide variety of different designs and unique features which set each AED apart and makes them a more practical choice for various communities.

However, all the bells and whistles aside, all AED’s practically function the same. One isn’t better at shocking than another. You may decide to choose an AED that is as small as possible to be able to travel with it, or you may choose an AED because you like the specific design that it has making it the most user friendly to you.

Variety of Choices

There are a multitude of different choices to pick from when purchasing an AED and it’s essential to know the specific things that you should watch out for when buying this device to ensure that you make the right decision and pick the best AED that’s perfectly suited to your needs and requirements.

Ease of Use

First and foremost, perhaps the key thing to remember when buying an AED is to ensure that it’s easy to use. While there are many feature-rich AEDs available that save lives, these can also end up being a bit complicated to use for the everyday passer-by or unnecessarily pricey.

Given the intense situations in which AEDs are usually required (such as in a home defibrillator situation), the best AED is a simple device in terms of its design and functionality so that anyone, even people who aren’t particularly familiar with these devices, can utilize them if need be. One example of such a design is the HeartSine Samaritan PAD 350P listed below, which has an incredibly simplistic and intuitive design.

Next, it’s essential to ensure that the AED you purchase comes with the necessary accessories. The best AEDs will come with electrode pads, a battery, and their own carrying case so that they’re portable and easily usable in any situation. It’s also worth looking into whether the AED you’re buying offers visual guidance or vocal instruction as this can be beneficial for someone who is attempting to use this device but has no prior experience with it.


You’ll have to make another choice when buying an AED, deciding whether or not you need an automatic AED or a semi-automatic AED. An automatic AED will, as the name suggests, automatically administer a shock if it detects irregular heart rhythms and sudden cardiac arrest (SCA). On the other hand, a semi-automatic AED will require some manual input from a user once it’s detected that a shock needs to be administered, though it can occasionally be more cost-effective.

Should you have the option of doing so, it’s worthwhile to invest in a fully automatic AED as it can save some much-needed seconds during a critical situation when things become a matter of life and death.


Fortunately, there are many AEDs available that fit the criteria mentioned above, and you can expect them to cost you anywhere between $1200-$3000 depending on how feature-rich and technologically advanced the final product is and what kind of warranty it may include.

IP Ratings

To compare the durability of AEDs, there is an International Protection Rating system used to classify different AED products. This standardized system of classification is known as the Ingress Protection Rating or IP Code. This two-digit code indicates the level of protection against various solids and liquids. The first digit indicates protection against solid waste like dirt, dust, gunk, and grime. The range of this rating goes from 0 to 6 with 6 being the best protection. The second digit indicates the protection against water and ranges from 0 to 8 with higher number meaning better protection. An X on either of the digit means that the device was not tested or is not rated. The need for durability against harsh conditions depends on the nature of use but it is always suggested to go for the higher rated product for any device that you may travel with or use in an outdoor setting.


Lastly, warranty is another important factor to consider when purchasing an AED device. It’s necessary to know what is covered in the warranty and how long the warranty lasts. Most of the time the accessories don’t come with a warrantee so it is important to keep that in mind or have extra. Additionally, some AED’s may come with a service plan and customer service assistance.
