• Water Filter ONLY for 3.5L InstantBoil Filtered Water Dispenser FB 7735F
• Special 4 Stage Water Filtration System - ion exchange resin and granular activated carbon sandwiched with 2 pieces of non-woven fabric

*Replace the filter ($8) every 6 months or after 1800L of water filtered to ensure highest filtration standard

Do note that it is common for excess carbon dust to be visible for the first few dispenses. 

**To prepare the filter for use, please fully submerge the filter horizontally in water for 2-3 hours to remove excess carbon dust and to improve water filter flow. Place any object on top of the filter to prevent it from floating. Please note that it is normal for the water to be cloudy during the soak as the excess carbons are being removed - this will not happen when the filter is working upright. After this process, the filter will be ready for use!
