Description
xMaintain clean airflow and dependable performance with the Phoenix 5L Oxygen Concentrator Inlet Filter (part number PRTSOC016). This replacement inlet filter captures dust, dirt, and airborne particles before they enter the concentrator — protecting internal components and maintaining efficient oxygen production.
The inlet filter is a key part of the air intake system, preventing contaminants from reaching sensitive components such as the compressor and sieve beds. Routine inspection and replacement help ensure consistent oxygen output, proper airflow, and longer equipment life.

This is the Phoenix 5L's inlet filter (PRTSOC016) — sits deeper in the air intake system, protecting the compressor and sieve beds. The Phoenix 5L also has an outer cabinet filter (PRTSOC015, sold as a pair on a separate listing) — both are part of standard maintenance.
Compatibility
