Carrier KH43LS160 Liquid Line Filter Drier for HVAC Systems

The Carrier KH43LS160 is a genuine OEM liquid line filter drier engineered to protect the refrigerant circuit in Carrier, Bryant, and Payne HVAC systems. Installed in the liquid line between the condenser and the metering device, this filter drier performs two critical functions: absorbing moisture from the refrigerant and capturing particulate contaminants that could damage downstream components.

Key Features:

• Genuine Carrier OEM part — manufactured to exact design specifications for reliable, drop-in replacement
• Dual-action desiccant core removes moisture and neutralizes acids from the refrigerant circuit
• Integrated filter element traps particulate debris, protecting expansion valves and compressor components
• Compatible with CFC, HCFC, and HFC refrigerants including R-22, R-410A, and R-407C
• Preserves existing equipment warranty and maintains agency listings and safety standards
• Proprietary design specifications not available to aftermarket parts manufacturers
• Meets Carrier's exact part design life testing for maximum reliability and durability

Using a genuine Carrier filter drier helps prevent refrigerant system freeze-up, corrosion, and premature compressor failure — all common consequences of moisture and acid contamination. The KH43LS160 is the correct OEM replacement for applicable Carrier equipment and should be replaced whenever the system is opened for service.
