All of these electrical appliances can be remedied by keeping leafy plants nearby. Not only do the plants reduce the radiation, they also supply oxygen through their metabolic process. The more appliances you have the more plants you need to be in the room. The rule of thumb is to use at least one plant for every appliance. For larger appliances try to use two plants instead of one.
Flowers also have a special place in feng shui design.
Flowers add energy to a home with their colors and shapes. They are most effective when taken care of, so make sure to trim the stems, change the water and remove any dead flowers daily. You may use artificial flowers as long as they are made from a suitable material such as paper or silk. If you are thinking about using dried flowers they are less acceptable due to the fact that they symbolize decay and death. But neither artificial or dried flowers are as effective as living plants.
