How often should I replace the air filter in my ventilation unit?
Air filters in ventilation units should be replaced with a frequency of at least twice a year – or as required.
Visually inspecting the filtration medium (pads/filters) in your ventilation appliance is an easy process. Periodically check your air filters. Upon inspection, if filters are visually discolored they should be replaced.
Clogged or old filters which are overdue for replacement can affect the performance and air flow rate of your ventilation device. Maintaining fresh filters will ensure the highest level of air filtration for the health and well being of occupants.
Ventilation units from STIEBEL ELTRON will indicate when it’s time to change you filters with an icon in the controller display.
