PEMF therapy – 7 steps to purchase the right device


Do you want to be sure to choose and buy the right PEMF therapy device, guaranteeing you long and happy use for years to come?

This article is a bit long, but worth the read. Let’s get started!

7 actions that will save you money and, at the same time, ensure you select the best PEMF therapy device from all of those available on the market, to improve your health.

“A PEMF therapy device is forever”. Joking aside, there is a kernel of truth. If you choose the right device, and follow the instructions you find here, the investment you make will be a crucial asset for your health and that of your loved ones. Also for many years to come.

These are the key points that will enable you to choose the most suitable device for you and your loved ones:

Get informed

The most important thing to realise is that there is not one single device that can satisfy everyone’s requirements and needs, i.e. one PEMF therapy device that is better than all the rest.

There are dozens of devices on the market produced by a myriad of manufacturers. Manufacturers bring to the market their own philosophy and specifications that they believe are “unique” compared to all the others.

Those referred to as PEMF (pulsed electromagnetic fields) have been the subject of many years of studies that confirm their worth. PEMF therapy offers real and tangible benefits in countering many diseases and debilitating physical conditions.

Electromagnetic fields act on the body mechanically, electrically, chemically and magnetically, combining all these factors together.

So, before choosing the brand, the technical specifications and the parameters, the most important thing, first and foremost, to consider is:

  • Your doctor’s opinion about your disease and/or physical condition
  • Your budget
  • Your current state of health
  • Your lifestyle
  • Your clinical history

With this complete picture you can start to look for a specific device and brand.

Identify “our actual” characteristics and needs

Follow this section carefully because this is perhaps the most important part of the article.

It is necessary to ask yourself a number of questions to narrow down the options and make the right choice:

Do you have a sedentary lifestyle or are you a sporty person? Do you have a chronic health problem or a temporary discomfort located at a specific point?

Do you want to take care of yourself only or the entire family? What is the maximum amount of money you can afford to spend?

Chronic diseases and conditions require different stimulations than therapies performed to keep one’s body healthy.

If your objective with PEMF therapy is to help maintain a general state of wellbeing, I suggest you opt for an “entry level” device. A device that emits an electromagnetic intensity of medium power and that only has a few programmes and frequency levels. The price should be a lot lower than that of super-professional top-of-the range devices.

If, however, you suffer from chronic pains or you are faced with very serious conditions or injuries, it is better that you choose a more advanced device. A PEMF therapy device capable of providing high therapeutic intensities and having two independent channels to simultaneously use two applicators in different areas of the body.

If the device is for the entire family, it is important that it has a range of programmes, intensities and frequencies able to meet the needs of all members.

If you often travel for work, drive long hours or are always jet setting around the world, then you need an extremely portable device. One that can also run with batteries and be rechargeable from any means and in any country you visit.

If the PEMF therapy device will be mainly used by an elderly person who cannot be assisted, it is better to choose a very simple machine, with only a few buttons and simple programmes to activate.

Now you see that the right choice involves first establishing your needs, habits, lifestyle and general health condition.

Let’s move on to look at the next point.

Understand the technical characteristics

A PEMF therapy device must be evaluated in terms of its both construction and magnetic field emission. We are now going to talk about the most important parameters to consider such as intensity, frequency, number and type of programmes, and applicator features.

It is important to know these aspects to adapt them to our needs and health conditions.

If you want to look at these concepts in more detail, you can also read:

  • Low-frequency and high-intensity PEMF therapy
  • High-frequency and low-intensity PEMF therapy


Regardless whether the electromagnetic energy supplied is low, medium or high, the therapy will always be effective. So, even devices with lower therapeutic intensities, if well designed, will still be beneficial.

What is important to understand is that, depending on the condition and part of the body to be treated, some intensity values are more suitable than others.

Let’s look at an example:

For treatments on areas of the body where the skin is thick (e.g. femur or overweight patients), an electromagnetic intensity that is too low will penetrate less effectively. The same applies in the case of fractures and, as a consequence, the presence of plaster or braces.

This does not limit the therapeutic effect, but simply requires a longer treatment time to achieve the same result as higher intensity therapy.


It is important to know and remember that even if there are devices on the market that use very different ranges of frequencies, the healing principle of the therapy is just the same and still effective.

Low-frequency PEMF therapy applies a magnetic field with typically medium-high intensities but at low frequencies (maximum 150 Hz). It is particularly indicated for the treatment of hard tissues and delayed bone union (osteoporosis, fractures, post-operative recovery for prosthetic implants, etc.).

It is also indicated for treating pain and, in general, to restore the correct functional balance of cells. As a result, it is also effective in the treatment of soft tissues.

High-frequency PEMF therapy is based on the emission of small “packets” of high-frequency radio waves, between 18 and 900 MHz, but at low intensity. It is more suited to the treatment of conditions affecting soft tissues (e.g. muscles and tendons).

Once again here, there is proven effectiveness in fighting pain.

Irrespective of the technology, make sure the device has programmes with frequencies that match the indications given by the specialist and medical literature on the subject matter.


The intensity of the magnetic field significantly reduces as the distance from the area to be treated increases. Therefore, the ideal situation is contact between the emitting source and the patient’s skin.

If you compare modern PEMF therapy applicators to those from the past, those available on the market today are much more comfortable and suitable for a variety of different treatments.

One of the most important aspects is wearability of the applicator itself, which, once put on, must be firmly attached to the part to be treated.However, it should not be too uncomfortable or painful for the patient.

An example of a good applicator is that consisting of two or three solenoids inserted inside adjustable elastic belts. They are easily adapted to most areas of the body without too much difficulty.

For “total body” treatments that require treatment distributed throughout the entire body there are magnetic mats or mattresses with various solenoids inside them. They emit the magnetic field over a very large surface area, effectively covering the whole zone to be treated.

Some of these best examples of this type of applicator are those that emit over the entire surface of the body, such as Osteomat.

For applications that require high therapeutic intensities, there are individual and physically larger solenoids. They guarantee a high intensity treatment, thus avoiding excessive overheating to which applicators with smaller loops would be subjected.

The pair of CV2S2000 solenoids is part of this kind of accessory.

The most used applicators in the past (but still on the market) are electromagnetic cylinders. Often very large, they were installed on beds where the patient had to lie down for the therapy. Their biggest drawback was the very low intensity of the electromagnetic field emitted. This is mainly due to the distance from the surface to be treated.

An effective alternative is the newly developed cylinders, which are much smaller than they once were. They make it possible to treat the peripheral areas of the body, ensuring an adequate delivery in terms of power.

The Cil-Mag is one of these. There are also other important factors to consider.

In addition to the specific needs of the patient and the technical characteristics of the device, it is very important that you:

Evaluate whether to rent or purchase the equipment

Some manufacturers have opted for the equipment rental route. Some physiotherapy centres also buy and then rent equipment to their patients.

Although, generally, modern PEMF therapy devices are extremely well-built, it is important to make sure that the devices and accessories rented are always properly maintained and sanitised. It is impossible for us to know who used the equipment before, so it is always better to do so just to remove any doubts.

Usually, if the patient requests, an option to purchase the equipment is given, discounting part of the amount spent on the rental.

So, is it better to rent or buy the device?

Regardless of the budget you have available, there are some excellent PEMF therapy devices on the market that cost on average less than the amount necessary for a rental cycle.

With a lower cost, therefore, we will have a new device that, if properly maintained, will last many years.

In most cases continuous PEMF therapy use is necessary, which is why it will be worthwhile and less expensive to buy.

Some examples of conditions that require continuous therapy are chronic diseases such as osteoarthritis and osteoporosis, and resistant conditions such as algodystrophy.

Test pre and after sales support

For sure, this is one of the most important “human” factors that should help us in deciding what device to buy.

Do not worry, it is very easy to work out if the company is able to help you make the right choice and if it will be there to help you, if necessary, later on.

Try calling them or sending an email to ask for information. Explain your needs or clinical condition. Ask for advice about which device to choose from their range.

Did they reply in adequate time? Were they friendly? Did the staff on the phone or email seem competent to you or did they only provide “scripted” answers that you can find anywhere on the web?

Common sense will tell you immediately if they deserve your custom and your money.

As for after-sales support, on the other hand, ask the retailer or the company to clearly explain their procedure for providing technical support in the event of repairs. Also ask if you have to pay anything and the average repair times.

Here too, you will be able to tell if the person you are dealing with is professional or not.

Know the manufacturer

It is important to place our trust in new companies and their work, but it is much more important that you invest your money in the best way possible.

Make sure that the PEMF therapy brand you want to buy comes from a well-established company that has been in business for years and that, at least, is known nationwide.

It would also be better that the manufacturer of your PEMF therapy device is around for a few years after you bought it, don’t you think? If in the future you need accessories, support or spare parts, surely you need someone to respond to your requests.

Your PEMF therapy device will be by your side for many years, so it is appropriate that the company that built it is there too.

Check the CE marking

All medical devices are recognisable by the CE marking followed by the number of the notified body that certifies the conformity of the product according to the medical devices directive.

We have reached the final and most vital aspect to consider before buying.

Your PEMF therapy device is and must be recognised as a medical device.

So, make sure that the device bears the CE marking that guarantees user safety.

Your safety and that of your loved ones is too important to put at risk by using poorly made and unprofessional equipment, don’t you think?

Now you know almost everything there is to know about PEMF therapy. Just a few final suggestions.

Right! We have reached the end of this comprehensive guide. If you have made it all the way here, I am very grateful and I really hope this article will help you in choosing your next PEMF therapy device.
