How long does the light have to be on before it starts to eliminate indoor air pollutants?
Testing has shown that the powerful effects of oxidation start happening immediately after the light is switched on. Normal everyday air circulation must occur in the room for the process to effectively work. Once the contaminants touch the surface of the light they are instantly killed. One WellnessLight advanced CFL is sufficient for a 200 sq ft room (19 sm) with an standard 8 foot ceiling. For larger rooms or rooms with high ceilings, two (2) WellnessLights are recommended.
