Foam Filters for GoodKnight 420 or 425

Foam Filters for GoodKnight 420 and 425

This Product DOES NOT Require a Prescription

Product Description

The pollen foam filters are designed to be used with the Puritan Bennet Nellcor GoodKnight 420 or 425 CPAP Machines. These filters are reusable and can be cleaned by using warm soapy water. The cleaning of the filter should be done weekly to ensure proper functionality. Never use a wet filter in a machine, so ensure the filter is completely dry before use.

Replacement of the filter is 1-3 months even though it is cleanable. Using a dirty filter can cause damage to the machine because a dirty filter makes the machine work harder when providing the user with the positive air pressure.
