Product Information

Protection against the adverse effects of Electromagnetic Radiation for homes and building spaces

Benefits of Harmony

✅ Stops the negative effects of all EMFs for anybody within its protective bubble

✅ Enjoy the peace of mind from knowing you are protected.

Harmony has been optimized in its design, manufacture and applications to meet the demands of everyone trying to function in our modern EMF-dense environment.

Harmony protects against the adverse effects of EMFs at home, in the office, school or any other space.  More specifically, Harmony compensates for the potential effects of Wi-Fi, WiMAX, Bluetooth, DECT, wired telephones, relay antennae, satellite communications, sub-6GHz 5G frequencies, electrical networks from low to very high voltage, geo-biological disturbances, microwave ovens, low consumption light bulbs, Smart meters and similar Smart technology, CPL (Carrying Currents Online), transport (car, plane and train).

All Comosystems products use CMO (Compensating Magnetic Oscillator) technology that is activated by the polluting EMFs surrounding it.  Activation generates a compensating signal that piggybacks on top of the harmful EMFs thereby stopping their adverse disruptions to our normal biological processes. In short, Harmony makes EMFs biocompatible within its 5.5m range in all directions.

With a Harmony, you and your family can live safely alongside technology without losing the functionality and benefits we enjoy from our gadgets and telecoms.

NB: Whilst the Harmony multifunction protection covers the broad source of electromagnetic pollution described above, we still advise you to use CMO devices with your mobile phone and laptop/tablet that are used in frequent close contact with your body. We recommend that you equip mobile phones with an Easycall, and use a PCZone for each laptop or tablet - especially if also used outside the protected area.  We recommend the Traveller to protect the wearer against EMFs when outside the home/office protective bubble. 

Check out the Bundles category for maximum surveillance protection and EMF protection from multiple devices in combination.


The Harmony should be placed as close as possible to the epicenter of the zone you wish to cover in your home or office. The most important areas to ensure are covered are those areas where most time is spent and/or where there is a higher concentration of polluting equipment eg living room, bedrooms, home office etc.


The Harmony creates an effective protective bubble zone with a diameter of 11m (ie 5.5m in all directions from it) which is sufficient for a house or office space of 100m² (1076 square feet or less) *.

If strategically placed high up on the ground floor or low down on the first floor in the centre of the building, Harmony can provide protective coverage for both floors. This will protect against the adverse effects from EMFs generated both inside the protective bubble and those coming in from outside it. The most important areas to ensure are covered are those areas where people sleep and spend most time, especially in close proximity to EMF-polluting equipment eg living room, bedrooms, home office etc.

Note: the influence of the CMO on its environment is given as an approximate indication, but cannot in any case be a precise measure in every situation which will vary according to wall thickness, placement and building materials.  The figures provided are the limit of effectiveness of the corrective effect which has been calculated by the RAC method (auricular-cardiac reflex).

For larger homes or those with an irregular floorplan, it might be necessary to combine with one or more Harmonys/XLs for maximum efficient protection.

Instructions on how to set up and use your CMO devices once you have them can also be found here.


Harmony is a cone with a beautiful aesthetic violet colour.
Dimensions: Cone with 69 mm diameter, 53 mm height - 165 grams weight 
Composition: CMOs are passive magnetic oscillators, operating without energy input: they activate in the presence of artificial electromagnetic fields.
The aluminium shell is made of 100% aluminium.
Chemical composition of the active solution: microcrystalline saline solution treated electromagnetically.
