Modern Feng Shui helps clear the EMF's, Toxic Chemicals around your home. These elements were non existent when Feng Shui began. Modern homes have TV's and Electronics in nearly every room. This Electro Magnetic Energy flows around the home intoxicating the good energies. There are cost effective remedies like placing the right "clean air" plants and correct placement of Hematite. Redecorating to relieve some electronics and place them away from where you sleep is important. Adding clean air filters to eliminate the toxins from cleaning products and furniture helps also. Although I highly recommend chemical-free cleaning products, regardless.
