The portable oxygen concentrator AirSep FreeStyle has to be used with an air intake filter. This filter prevents dust and other large particles in the air from entering the unit. Before you operate your FreeStyle make sure the air intake filter is clean and positioned correctly.
The air intake filter is washable and re-usable. Please clean this filter every week or often. Take the air intake filter out of the POC and clean it with warm, soft soap water. Now clean the filter with fresh water and dry completely before puting in your POC.
Article number AirSep: FI 144-1
