Sunset OxyHome Foam Cabinet Filter

The foam cabinet filter is located on top of the filter box and should be cleaned weekly using warm water and a mild detergent. Allow the filter to dry completely before reinstalling and using the device. Regular cleaning of the gross particulate filter is essential for the safe operation and performance of the unit. For optimal performance, the filter should be replaced every 6 months, or sooner if it becomes damaged, worn, or starts falling apart.
