Frequently asked questions:
Q: Why is it difficult to twist the new filter into the filter housing?
A: Pressure inside may cause the expansion of connector, increasing the installation difficulty. Therefore, it is recommended you push the new filter in with a little bit of force, but not too hard.Then turn it clockwise.
Q: If I do not change my filter every 6 months, can this damage the system?
A: Yes. You must replace the filter every 6 months or sooner if water flow is reduced or if there is heavy sediment. Filters left in longer will fatigue, degrading the filter performance.
Q: Do I need to flush the filter before using?
A: Yes. It is highly recommended you flush the filter before using. Water filters are made from advanced coconut carbon block, so there are some carbon fines in the filter. You need to flush firstly to remove those carbon fines to get clean water.
