Keep it clean and tidy: Wipe the outside of the machine with a soft cloth, especially around the air vents, to keep dust away. This helps the machine “breathe” better.
Take care of the nasal tube: Wash the nasal tube (cannula) once a week. If you use it every day, change it about every 2 months. If you use it less often, replace it every 3–6 months to stay fresh and hygienic.
Check the filter: The filter keeps out dust and pollen from the air. Clean it once a month to make sure the machine lasts longer and runs smoothly.
