Before you buy, it's a good idea to accurately measure the space you want to secure against the level of EMF radiation that exists around you. Our kits can be used in residential and commercial areas and while we recommend that the main carbon plate is attached directly to your fuse box, even if you are unable to attach it to the circuit breaker panels of your space, you can still get the full advantage of the harmonizer kit you select. The office harmonizing kit is ideal for use in larger spaces, workplace environments and office venues where the fuse box or circuit breaker panels are not easily accessible and can still be made safer when EMF radiation exposure is a constant threat. Once you've determined how much space you need to harmonize to protect yourself and others, you can select the home harmonizing kit level that provides the sufficient amount of protection necessary.
