Home oxygen therapy can provide essential support for those suffering from chronic respiratory diseases such as COPD. However, to ensure that the device works reliably in the long term, maintaining your oxygen concentrator and following basic care tips are key. In this article, we will detail how to properly care for your device, especially the VARON VH-3 model, which is an outstanding choice for home therapy.
Why is regular maintenance of an oxygen concentrator important?
With continuous use, the oxygen concentrator draws in a large amount of air, which may contain dust, pollen, and other contaminants. Over time, these can clog the filters, reduce performance, and even lead to failure. Therefore, maintaining your oxygen concentrator is essential to extend the life of the device and ensure a stable oxygen supply.
Proper care not only improves the performance of the machine, but also increases the safety of the user. Regular cleaning and replacement of filters are one of the most important care tips .
Basic care tips for your oxygen concentrator
The following care tips will help you to keep your device in good condition and working reliably:
-
Surface cleaning: Wipe the exterior of the device regularly with a slightly damp, soft cloth. This will help remove dust and dirt.
-
Cleaning the ventilation slots: Use a soft brush or dry cloth to remove dust from the ventilation slots.
-
Cleaning oxygen nasal cannulae: Wash the nasal cannula once a week and replace it every two months if used intensively daily. For less frequent use, replacement is recommended every three to six months.
-
Filter maintenance: Clean the filters monthly and replace the cotton filter after 100-200 hours of operation.
-
Nebulizer and mask: Clean thoroughly after each use and allow to dry.
These simple steps will significantly extend the life of your device and ensure that you are always breathing pure oxygen.
