This reusable and washable particle filter covers the air intake screen on the InogenOne G4 Portable Oxygen Concentrator, filtering out dust and contaminants to ensure a clean, clear and unobstructed air flow into the system. A particle filter must always be in place during operation of your InogenOne G4 POC.

Usage Information: G4 Particle Filters should be cleaned at least once a week (or whenever dirty) to ensure the ease of air flow. For best results, clean the particle filter with mild, unscented dish soap then rinse completely with water. 

Make sure to let the filter dry completely before reinserting it into your concentrator. Filters should be replaced whenever they become damaged or misshapen. For complete instructions review the documentation that came with your equipment.
