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: 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.

    DirectHomeMedical always ships promptly. It appears that they have had everything I have ordered so far in stock. Their prices are usually average or better. As far as the particle filter is concerned, I very much like my G4, but in my opinion, this filter is its weakest point. I have not damaged one yet, but this filter should have a guard over it.
