Buyer’s (Features) Guide to iMRS Prime

(Updated April 2024)

The new flagship iMRS, iMRS PRIME, is officially released in May 2020 globally. It comes with numerous world’s first for a home-based PEMF system, including an integrated far-infrared system in the full-body Mat, a Split mode operation, and many more. The iMRS Prime inherits almost all the features from its predecessor, iMRS (or iMRS2000), and in addition, added a number of new hardware and software features. Despite positioning as a home-based system, the new iMRS PRIME has introduced many new features that make it well-equipped for clinical and research purposes too.

iMRS Prime PEMF system What's New

In this article, we share with you what was not usually detailed in the product brochure, giving you a better insight of the features and functionalities of the iMRS Prime system. We hope it can serves as a useful buying guide to your first iMRS Prime system, or if you are considering to upgrade your existing iMRS or Omnium1 system. For those who wish to learn more about the features of existing iMRS system, check out the We shall not revisit the existing features like iGuide, bio-feedback, base iMRS technologies like Organ Clocks, brainwave entrainment technologies to keep this article as compact as possible.

We suggest you visit to learn about the new features of the iMRS. The focus of this article is to discuss the practicability of the new iMRS Prime features for your purchase decision.

Key Features of iMRS Prime

  • A complete redesigned new hardware platform. 10.2″ touch screen panel based on a customized multi-cores platform.
  • Separate standalone connector box that can simultaneously connect up to 6 applicators, 2 Exagon Brain and 2 Exagon Sense
  • Split system operation, controlling two independent PEMF and/or Brainwave Entrainment session concurrently
  • Integrated Hybrid Full-body mattress with integrated Far-Infrared technology so you can now use FIR and PEMF at the same time – known as Exagon FIR Mat
  • New Spot Applicator (Exagon Spot). This will replace the Probe applicator in iMRS system.
  • New Brainwave entrainment system (Exagon Brain) – with new hardware support up to millions of colour combination and manage, update your own music library – similar to OmniBrain in the iMRSone system.
  • Improved bio-feedback software – where the system now is able to keep the sessions history and export to a 3rd party HRV analysis software for more in-depth analysis.
  • 9 fast start programs (similar to Omnium1’s Quick Start) and new Solfeggio Scale 9 program, introducing new frequencies range that’s outside the standard four iMRS Organ Clock Programs, where all the rest of the 8 fast start programs are based on.
  • Program Mode – lifted the limit of 3 user profile button as in the old iMRS system. Now you can configure an unlimited number of user profiles.
  • Trial Mode. This software module allows trained and professional users to experiment and studies PEMF effect by allowing manual adjustment of frequency, waveform, intensity, and pulse duration characteristics.

Existing Features remain in iMRS Prime

  • iGuide software (in Expert configuration and above)
  • Manual setting of session – i.e. time, intensity (known as Manual Program)
  • Organ Clocks programs, 8 intensity levels, duration (1-60 minutes), switch polarity features
  • Standard PEMF Full-body mat with graduated intensity along 3 body sections (known as Exagon Mat)
  • Pillow applicator (now known as Exagon Pad)
  • One worthy mention is now for all configuration, including Basic and Advanced (previously known as Wellfit & Complete), you will have access to the highest intensity 400 and timer configuration at minutes interval, from 1-60 minutes, instead of just 3 intervals at 8,16 and 24 minutes.

iMRS Prime Models

The new iMRS Prime now comes in 5 different models or configurations, all are based on the same hardware platform. You can upgrade from one configuration to another without the need to re-invest in new hardware, except for one – the Hybrid Full-body Mat (Exagon FIR). You will need to purchase a new full-body Mat that has FIR feature integrated if you purchased the non-FIR Exagon Mat. The chart below shows the upgrade path, hardware and software included in each model.

As you can see from the chart, most configuration upgrades are incremental from both the hardware and software perspective. Software feature is activated via an activation code, which the company will provide you when you purchase the software module. The only exception is the Hybrid Far-Infrared Mat (Exagon FIR), as the standard Exagon Mat does not come integrated with FIR.

Fast Start Programs

iMRS Prime’s Fast Start Programs deserve a special mentioned here with the latest version 2.3x firmware (released April 2024). It has slowly evolved to become a more useful functions for daily and professional use with the inclusion of more customizable options for BRAIN and FIR temperature setting and the newer addition of longevity and cell training programs. Checked on the programmed specific here:

Hybrid Exagon FIR Mat

Exagon FIR Mat is one of the most exciting features introduced in iMRS Prime. Although the Far Infrared Heat (FIR) is already a common technology available for many decades, and with longer history then the PEMF, having the technology integrated into a PEMF system is still rare. FIR is part of the Electro-Magnetic Frequency Spectrum that is known to resonate with the water molecules in our body, generating heat and improve body circulation. FIR spectrum is also the natural and beneficial wavelength spectrum coming from the Sunlight. FIR is the most pro-life EMF from nature. Learn more about FIR.

There are several benefits the FIR integrated PEMF mat has over a pure PEMF. First and foremost is the effect of increasing our body temperature, hence increasing our core body temperature, promoting body immune system response and circulation. Many people with chronic conditions usually have relatively low core body temperature. By increasing the body temperature by just 1-3°c, it can help activates our body immune systems. Second, is the fact that the warming comfort sensation is an assurance to user about the “immediate” effect of the session, since most of the time users may not feel anything during a pure PEMF session.

Hybrid Mode (with Exagon FIR Mat) is only available in 2 models – Hybrid and Trial Models. Currently, you can only do a direct upgrade from Expert model to Hybrid. There is no direct model upgrade from Basic and Advanced model to Hybrid model. However, you still can add-on the Hybrid FIR mat by purchase an additional Exagon FIR Mat and Hybrid Software Tool.

Do you need Hybrid Feature

This is definitely a good-to-have feature. Sensationally, this will be a very different experience for you, as compared to just the pure PEMF session. It’s a “WOW” factor to many. However, there is a small consideration in term of application time. Different from PEMF stimulation, FIR needs to apply slightly longer time in order to have a better effect on your body, usually 16 minutes or more per session will be ideal. Also, it will take at least a couple minutes to heat up to the desired temperature. Hence if you are having an 8 minutes session, you likely not get the desired effect from the FIR. So do expect the overall application time to slightly increase when using the FIRto at least 16 minutes or more.

Second, is to set your expectation on this “heat’ therapy. The FIR and temperature setting in Exagon FIR Mat is not designed for you to sweat out profusely (though some people might) or use it overnight as a heated mattress. It is designed to increase your body core temperature and improve circulation in the body for a better overall effect during the PEMF session. If you need a serious hyperthermia session or heat therapy, look for dedicated FIR solution, or FIR sauna type of system.

People with consistently low body temperature, like cancer patients, cold feet, seniors, or poor immunity can benefits from increased body temperature using FIR.

If you are using this system in a centre or as a service, then this will be a very useful feature to consider, as in such cases, general treatment time is around 20-30 minutes per session, and your patients can also benefit more from a single session, not to mention the added sensational feeling.

Update April 2024: More than 80% of system sold to date are Hybrid. Feedback from FIR owners are overwhelmingly positive. The effect of heat seems to amplify the benefits and effect of PEMF session.

Split Mode

Leveraging on the matured virtual technology and powerful multi-core processors comes with the new iMRS control system, the new system is able to spawn two virtual systems to allow them to individually control separate physical devices connected to the left and right section of the connector box. This feature is available in Expert, Hybrid and Trial models. This is quite a significant feature and serves a very useful purpose for many scenarios. The split mode is different from daisy chain applicators or having multiple applicators sharing the same session. In Split, you are practically running two separate iMRS Prime systems on the same hardware (i.e. same touch control panel and connector box). The connector box is split into left and right section. So effectively have virtual session A control applicators connecting to the Side A, and vice versa.

Split mode, however will not support Hybrid and Trial Mode, mainly due to the support of the use of FIR Mat. The current (power) needed to support FIR mat is more than what the system and support and designed for. Hence Split mode can only support non-FIR applications.

Do you need Split Mode?

Split mode feature is available from Expert Model and above. You can also purchase this feature as an add-on if you decide to get a Basic or Advanced model. Split Mode software tool license. This feature is useful if you have family members at home wishes to use the system at the same time – i.e., one using full body mat and one using spot or pad for local treatment. This feature won’t be recommended if your intention is to use two different applicators on the same person, i.e., using a full-body mat and at the same time using a spot. Reason being the programs used by different applicators can be different, and this will cause interference.

If you are running a service centre and need multiple non-FIR PEMF systems, then this will be a very practical and cost effective configuration to get. For instance, if you have 2 beds, then instead of getting 2 expert system, you just need to purchase 1 Expert system and 1 additional full-body mat. This will greatly save your investment cost.

Bio-Feedback HRV (Exagon sense)

iMRS’s bio-feedback system (previously known as iMORE) based on heart rate variability (HRV) reading is not a new feature.  In the new iMRS PRIME, the iMORE (now known as Exagon Sense) gets an upgrade with the capability to display blood oxygen level real-time. In addition,  the HRV data collected during the sessions can now be exported to a 3rd party HRV analysis application for further investigation. The hardware (finger sensor) essentially remains the same hardware, but with a darker tone. However with the new Prime system, the SENSE reading is much more reliable and consistent as compared to iMORE. This likely has to do with the overall Prime system. Nevertheless, most of the enhancement lies in the software piece.

What’s New:

  • New display interface that shows also the Oxygen level (SPO2) on top of the HRV and Intensity level. The SPO2 is not used in the assessment, hence the algorithm in evaluating HRV remains largely the same
  • The session history can be kept and export to third-party software, Kubios HRV analysis software for further assessment.

The advantage of using the Kubios software, however, is the ability for you to understand various HRV parameters including your recovery (energy reserve) and stress index level. This can give you an overall indication of your overall health, and trend over time, a very useful insight to your health.

Do you need Exagon Sense?

Our recommendation for bio-feedback remains mostly the same as in our previous recommendation in our iMRS system buyer’s guide. If you are a home user, this is really optional. While the 3rd party Kubios software is a plus if you are prepare to install the software system on a PC (Windows or Mac), export and analyze the reading.

New Localized Applicator (Exagon Spot)

The two-piece round small pad introduced in iMRSone Omnium1 as OmniSpot proves to be a popular and practical replacement for the Probe applicator in the previous iMRS systems. The functionality of the Exagon Spot is similar to the OmniSpot as in the Omnium1 system. The choice of getting the Exagon Spot will decide your purchase of either the Basic or the Advanced model. If you are expecting to treat joints or shoulder pain, the getting the additional Exagon Spot should seriously be considered. The application of Spot is much easier as compared to Probe, as this is mostly hands-free. You can also spread out the Spot and use it across a larger area.

Exagon Spot is the latest high-intensity applicator that replaces the Probe in iMRS. The magnetic field not only works directly above the Spot applicator but also spreads itself out in all directions. The flux density of the spot applicator is less than or equal to 120 μT at its highest intensity. The placement of the coils across from each other will generate a so-called Helmholtz effect (meaning a homogeneous magnetic field). It has a flexible attachment belt for a more simple and practical application.

Other Features to Consider

Brainwave Entrainment (Exagon Brain)

Previously known as iSLRS, the new Exagon Brain enjoy an upgrade in both hardware and software department. Besides the new hard case outer shield, the eye set now offers 3 colours (red, green, blue) each with 256 colour shades adjustment, with a possibility of millions of colour combination. This is similar to iMRSone’s OmniBrain feature. Refer to for a detailed description of this technology. Learn more about Brainwave Entrainment technology. With the new BRAIN, you can now also upload your own music files, and group them into your own custom playlist.

Audio-Visual Brainwave Entrainment technology is good for mental state regulation – i.e. let your feel more focus or relaxed in most cases. Not everyone enjoys flashing light, and some may report nauseous or headache. It is always good to try this option out before deciding.

Trial Mode (For Professionals/Experts only)

Trial Mode is the highest software configuration of Trial. You can consider Trial as a D.I.Y. mode, where you are able to custom your own waveform, frequency, intensity, pulse duration and break, timing, etc.. This feature is designed for PEMF professionals or clinical researchers who need specific settings for treatment or experiment use. This option is NOT FOR HOME USE, as wrong configuration & application can be harmful to your body.
