Support
--Regularly maintain the appearance of the oxygen concentrator and carefully wipe around the vents. To remove dirt, rub the surface lightly.
--Clean the nasal cannula at least once a week. If it is used daily, it is best to change the nasal cannula every two months. If you don't use it frequently, replace it every three to six months.
--The filter of the oxygen generator can remove dust, dirt, and pollen from the air. Cleaning the filter once a month can extend the service life of the unit.
