Filter Resin For Gravity Feed Iron
This "SOFTENER COLOR CHANGE FILTER RESIN" makes pure water for the "STEAM IRON" by filtering tap water through cation (honey color) and anion (dark blue) ion exchange resin which completeremoves calcium and magnesium particles. Consequesntly, undesirable mineral deposits, such as calcium nitrate , dono collect and harden inside the iron , and the necessity for frequent cleanings is, therefore, greatly reduced.
When the resin's capacity for absorption has been exhausted color of anion will have changed from dark blue to rust. This color changed is the signal to replace the old resin with the new resin
