AutoFlo Complete Replacement Filter Kit

Includes one (1) Inline Water Filter Replacement Cartridge and one (1) Z-100 Mineral Deposit Eliminator

*Note: Because of varying water conditions in the Denver Metro area, we recommend changing the inline water filter once (or twice if needed) per heating season. Perhaps once in the Fall and once along about January or February. The Z-100 Mineral Deposit Eliminator needs to be checked (and possibly changed) at the start of each heating/humidification season (around September 15th).
