Whole House EMF Protection System Make your home an EMF protected zone that feels good and IS good for everyone within it. Which kit to order? If you have access to the fuse box, add up the total amount of square footage the fuse box services and order as follows: Kit 1500 – up to 1,500 sq. ft. (1 large & 4 small plates) Kit 2600 – from 1,500 to 2,600  sq. ft. (1 large & 7 small plates) Kit 3700 – from 2,600 to 3,700  sq. ft. (1 large & 10 small plates) Kit 4800 – from 3,700 to 4,800 sq. ft. (1 large & 13 small plates) To calculate the correct square footage, add up all the area serviced by the fuse box even if you aren't using those areas. Include every room, basement, attic, garage, outbuildings, etc. that are serviced by your electricity. The Carbon + Home EMF Harmonizer Kit works by harmonizing the entire electrical network throughout the total area covered by the fuse box. If you have an area larger than 4,800 square feet, you'll need to purchase one of the Home Harmonizer Singles for each additional 400 square feet. If you DO NOT have access to the fuse box, you will purchase a number of Home Harmonizer Singles based on the size of the area to be covered: Up to 1,000 sq. ft. – purchase four Singles For each additional 375 sq. ft. – purchase one additional Single How does it work?
