Sorry, there was a problem. Please try again later.The plasma function works by breaking down pollutants' molecular structure through the bonding of negative and positive ions. The PlasmaPro 200S, 400s, and 600S models all have an optional plasma function. Please note that the PlasmaPro models also have ozone-free versions on our website (Core 200S, 400S, & 600S).
