Does a Sanuvox have to run 24 hours a day?
Induct models are designed to run 24 hours a day. That is not to say that they will. Induct models have either a sensor (R4000GX) or are hardwired (R1700GX) to the homes ventilation system, which means the purifier, will only run when the fan is on. The portable purifier (P800GX) can be used all day or can be used when the need arises. WHAT MAINTENANCE IS REQUIRED? Besides the changing of the lamp, no other maintenance is required for a Sanuvox Ultraviolet Air Purifier (R1700GX, R4000GX & P800GX). Sanuvox Saber APR requires cleaning of the Lamp depending on where it is installed.
