SoothOil Car Diffuser uses what scientists called the "Engulfing Method". This is a special method developed by Dr. Chang, which uses the ionized body of the air to remove any unwanted material in the air. By adding essential oils, such as Eucalyptus or Tea Tree, the harmful substance in the air will be removed up to 99.96%.
"Engulfing Method" allows the ionized air particles to capture any bacteria or virus in a capsule bubble, and then destroy it with ionic energy. This way, the air will be clean almost instantly because there won't be any delay at all.
