Buying Guide

Key purchase considerations help tailor choices to individual therapy needs and equipment configurations.

• Safety features: Look for a 6 PSI pressure relief valve and metal check valves to prevent backflow and reduce fire risk. These are important for devices with long run times.
• Compatibility: Confirm fit with your concentrator’s capacity (5L or less is common for many bottles) and interface type (spiral-type or DISS/hose connectors).
• Materials and durability: PP bottles are lightweight and non-toxic; ensure edges are smooth and the cup is thickened for resilience during lid changes.
• Water level indicators: Clear min/max marks help maintain proper humidity without overfilling, which can affect performance or safety.
• Ease of maintenance: Reusable bottles with simple connectors and easy disassembly support quick cleaning and reduced risk of contamination.
• Standards compliance: UL2208, EN ISO8359, and other safety standards indicate verified safety practices; prefer products that reference these standards where available.
• Kit completeness: Some sets include extra tubing, cannulas, or connectors, which can simplify setup but adds cost—evaluate what you actually need.

Depth of options varies by valve design, interface type, and included accessories. When selecting, consider your daily usage duration, environment (home or clinic), and whether you need multi-user versatility or single-patient reliability.
