As the heating season begins, make sure your ventilation unit (air handling unit) is working efficiently and delivering clean, fresh air throughout your home. Check the filters, airflow, heat exchanger, and condensate drain to prevent unpleasant odours and system faults. A well-maintained unit saves energy and ensures a healthy indoor climate all winter long.

Manufacturers recommend changing them every 6 months under normal conditions, or every 4 months in polluted areas. Learn the key signs that your filter is clogged and how to choose the right replacement interval.

Poor air quality has a direct impact on health – from coughing to serious heart conditions. The greatest risks come from fine particles, gases, and volatile compounds that penetrate deep into the lungs and even the bloodstream.

Protection is simple: use F7 class filters, replace them regularly, and ventilate your home properly. This way, the air indoors will stay cleaner than outside.
