How is a machine rated for 3000 square feet supposed to work through the walls?
No tabletop air purifier can purify air in the entire home. Radio waves can pass through walls, If you want to distribute ozone through your entire home you need an in duct ozone generator like our Air-Duct 2000. We cannot stress this enough; Square footage ratings by other manufacturers are meaningless! It is the total ozone output in mg/hr that counts!
