The LG AirFit H12S1D is a wall-mounted split air conditioner designed to maintain a comfortable climate in rooms up to 35 m². It utilizes inverter technology to provide efficient cooling with a capacity of 12 kBTU/h (3.5 kW) and heating up to 4 kW, achieving an A+++ energy efficiency class that helps keep electricity consumption low. The system uses R-32 refrigerant, which is more environmentally friendly than older alternatives. To ensure the air you breathe is clean, this unit integrates a multi-stage filtration system including pre-filtration, an antibacterial filter, and ionization. You can manage the environment through six different airflow modes and adjustable direction settings, while the built-in dehumidification function helps reduce humidity on damp days. The white indoor unit measures 89.5 cm in width and 30.7 cm in height, blending quietly into most interiors. Connectivity is handled via Wi-Fi and the LG ThinQ ecosystem, allowing you to control the device from your smartphone. Practical features like auto-restart after power failures, a timer, and self-cleaning functions reduce the need for manual maintenance. The package includes both the indoor and outdoor units along with a remote control for immediate setup.
