Buying Guide: Key Purchase Considerations

• Humidification type and control: Choose models offering both warm and cool mist for flexibility. Auto humidity or app control helps maintain ideal relative humidity for comfort and nasal health.
• Capacity and runtime: Larger tanks reduce refill frequency, especially in shared spaces. Consider 4–6 liters for bedrooms, 6–11 liters for larger rooms or family use.
• Heated humidifier compatibility: Some CPAP machines require specific humidifier chambers or inline adapters. Confirm compatibility with your CPAP model before purchase.
• Maintenance and ease of cleaning: Look for easy top-fill designs, simple cleaning schedules, and components that resist mineral buildup to minimize maintenance.
• Noise level and sleep friendliness: Quiet operation (often measured in dB) contributes to better adherence, particularly for light sleepers.
• Water quality considerations: Distilled water reduces mineral deposits and white dust; some models include anti-mineral features, while others perform best with distilled water only.
• Smart features and integration: Apps, timers, auto-shutoff, and aroma or essential oil options can enhance comfort but may add cost. Ensure the features align with your needs and CPAP setup.
• Safety and filtration: Verify safety features like auto shutoff, overflow protection, and BPA-free construction for healthy indoor air.
