These original Philips Respironics brand foam pollen filters (with integrated blue carrier as shown) are designed for use with all DreamStation Series CPAP/BiPAP Machines. Foam pollen filters are reusable and should be cleaned on a regular basis and replaced as needed due to wear and tear. Pollen filters are an essential component for your CPAP therapy due to their ability to remove irritating dust, pollen, and tobacco smoke particles from your CPAP airflow.
