This is the complete humidification set for home oxygen: the 500 ml bubble humidifier bottle plus the connector tube that links the bottle’s outlet to your nasal cannula. Setup: fill the bottle with distilled or cooled boiled water to between the MIN and MAX lines, screw it firmly onto the concentrator’s humidifier outlet, connect the tube from the bottle outlet to your cannula, and set your prescribed flow. Bubbles in the bottle confirm oxygen is flowing. Hygiene is essential: change the water daily; clean and disinfect the bottle weekly; replace the connector tube when it discolours. Continuous flow only: never fit a humidifier to a pulse-dose portable concentrator.
