What is the Solar Refreshing Filter (SRF)?
The SRF is a deodorising filter filled with charcoal that absorbs tobacco smoke, pet dander and similar airborne contaminants. It helps remove odour from the air during the system’s operation. SFR’s deodorising property can be easily regenerated by placing the filter in the sunlight for 6 hours, every six months. Typically, the filter lasts for about three years.
