Disposable Ultra-Fine Filter for the Philips Respironics DreamStation CPAP Machine.
These Reusable Pollen filters are carried in a dark blue plastic shell with attached white filter made of polyester fibers.
PLEASE NOTE: The white filter material is permanently attached to the blue plastic shell. They are not designed to be detached from one another.
These filters are disposable and should be replaced after 30 nights of use or sooner if they appear dirty. To install an ultra fine filter in your DreamStation, slide the blue foam pollen filter out of the machine, securely snap the light blue ultra fine filter onto the base of the foam pollen filter, and insert them both back into the device.
