These FreeStyle Comfort gross particle filters are reusable washable replacements for the Caire FreeStyle Comfort portable oxygen concentrator. The pair includes one left and one right filter — designed for each side of the unit. Wash with warm soapy water and air-dry to keep your concentrator's intake clean and clear of debris.
Designed specifically for the Caire FreeStyle Comfort portable oxygen concentrator. Not interchangeable with other Caire models or other manufacturers' filters.
1 left filter + 1 right filter — designed for their respective sides of the FreeStyle Comfort. Important: they are NOT interchangeable. Each filter is shaped to fit its specific side. Make sure you install the left filter on the left and the right filter on the right.
Wash the filters with warm soapy water once a week, and let them air dry fully before putting them back in place. Replace when visibly worn, torn, or no longer cleanable.
How to clean the filters
- Turn off and unplug your concentrator.
- Note which filter came out of which side before removing them — you'll need to put them back in the same positions.
- Remove both filters and wash gently with warm soapy water.
- Rinse thoroughly and let them air dry completely — do not reinsert wet.
- Once dry, reinstall each filter on its original side (left filter → left slot, right filter → right slot) and resume normal use.
