About Luna G2 Replacement Water Chamber

The Luna G2 Replacement Water Chamber is a factory-compatible replacement humidifier water tank designed specifically for use with the 3B Medical Luna G2 CPAP and BiPAP machines. Heated humidification is an important component of comfortable CPAP therapy, helping to prevent the nasal dryness, congestion, and airway irritation that can reduce therapy adherence. Over time, the water chamber can develop mineral deposits, discoloration, or micro-cracks that compromise both hygiene and performance, making periodic replacement an important part of CPAP equipment maintenance. The Luna G2 Replacement Water Chamber is engineered to seat precisely in the Luna G2 system, ensuring a proper, leak-free connection with the humidifier heating plate. The easy-fill design simplifies nightly water top-offs, and the clear or transparent construction allows for easy water level monitoring. 3B Medical recommends replacing the water chamber every 6–12 months for optimal therapy performance and hygiene.
