- Compatibility: Check that the bottle’s interface fits your concentrator or CPAP device. Spiral-type and DISS-style interfaces are common, but verify the exact model or connector type before purchase.
- Safety features: A built-in pressure relief valve is essential to prevent over-pressurization. A metal check valve can prevent backflow and reduce fire spread risk in some setups.
- Materials: PP plastic is lightweight and durable; ensure the material is non-toxic and safe for medical use. Avoid brittle plastics that may crack under pressure.
- Water level indicators: Clear marks help you maintain the correct humidity without overfilling. Look for a full circle or clearly labeled minimum/maximum lines.
- Portability vs capacity: Smaller bottles are easier to transport, while larger bottles support longer therapy sessions between fills. Choose based on mobility needs and oxygen delivery requirements.
- Ease of setup: Quick and easy assembly reduces setup time and potential leaks. Quick-connect fittings and straightforward tube routing are beneficial.
