Philips Respironics Reusable Foam Filter for DreamStation Go Series CPAP Machines - 2 Pack

These reusable foam filters help clean the air that passes through the DreamStation Go by capturing dust, pollen, mold spores, pet dander and more with an 88% efficiency at 7-10 microns.

USAGE: These filters are reusable and should be cleaned after 2 weeks of use or sooner if they appear dirty. They should be replaced every 6 months or sooner if they appear damaged. For proper functionality either a disposable fine filter, or a reusable foam filter, should be in place at all time when the machine is in use. For complete instructions review the documentation that came with your equipment.

NOTE: The white filter material is permanently attached to the plastic filter housing. They are not designed to be detached from one another.
