As of October 2020, the DeVilbiss 525 and 1025 oxygen concentrator include an updated filter door. This air filter is not required for units with this new door.

The air filter and connector should be cleaned at least once a week. To clean, follow these steps:

1. Remove the air filter, located on the back of the unit. Remove the oxygen outlet connector (if used).
2. Wash in a solution of warm water and dishwashing detergent  
3. Rinse thoroughly with warm tap water and towel dry. The filter should be completely dry before reinstalling.

CAUTION– To prevent product damage, do not attempt to operate the unit without the air filter or while the filter is still damp.
