The cold season presents particular challenges for the respiratory system. For people with chronic respiratory conditions like COPD, an oxygen concentrator is an indispensable companion during the winter months . However, indoor air is often especially dry during the heating season, which puts additional strain on the respiratory system . This article will explain how to use your oxygen concentrator correctly in winter, protect your airways, and why the VARON Serene 5L is among the best devices on the market.
Serene 5 VARON 5L Premium Home Oxygen Concentrator
Cold and flu seasons: Why caution is advised
During the heating season, cold and flu viruses circulate more frequently in the air. For COPD patients, infection can be dangerous. A reliable oxygen concentrator like the VARON Serene 5L allows for convenient oxygen therapy at home, eliminating unnecessary trips and significantly reducing the risk of infection.
While healthy people already experience a certain feeling of tightness when wearing a face mask against the flu, this is even more burdensome for COPD patients. A stationary or portable oxygen concentrator provides a constant supply of oxygen without the feeling of being constricted by a mask. Using such devices is therefore not only comfortable but also safer.
Furthermore, it's important to note that if dry air irritates the airways , susceptibility to infections increases. A well-maintained oxygen concentrator with integrated humidification can help in this case.
Heated air and its effects on the respiratory system
Dry air from heating systems poses a significant problem for the respiratory system in winter. Constant heating often reduces indoor humidity below 30%. This dry air irritates the mucous membranes, making them more susceptible to bacteria and viruses. This can lead to exacerbations, especially in COPD patients.
An oxygen concentrator should therefore always be used with a humidifier in winter to moisten the air. This helps protect the mucous membranes. It is also recommended to ventilate regularly and, if necessary, to place a humidifier in the room. This improves the dry indoor air and reduces the strain on the respiratory tract .

Care and maintenance tips for the heating season
Regular maintenance is particularly important to ensure that your oxygen concentrator works reliably in winter and does not cause additional irritation of the airways due to dry air .
Care tips:
-
Clean the surface of the concentrator regularly with a soft cloth.
-
Remove dust from the ventilation grilles to ensure good air circulation.
-
Clean the nasal cannula at least once a week and replace it every two months with daily use.
-
Clean the dust filter once a month.
-
Replace the cotton filter after 100–200 hours of operation or as soon as it is visibly dirty.
These measures keep the oxygen concentrator hygienically clean during winter , and prevent additional strain on the mucous membranes irritated by dry air .
Comfort and safety for COPD patients
The VARON Serene 5L features an intuitive LCD display that allows for easy monitoring of oxygen levels, internal pressure, and operating time. Safety indicators warn of power outages, pressure fluctuations, or insufficient oxygen concentration.
For COPD patients, this means: more safety, less stress and a better quality of life – especially during the heating season, when dry air makes airways more sensitive.
