Product description
FILTERING MATERIAL: Modern, synthetic two-layer filtering material which provides less air resistance (and therefore less energy consumption), high filtration efficiency levels (in the form of dust absorption), and a long filter life (involving low pressure drops). The filter complies with standards EN 779: 2012 and ISO 16890
REPLACING THE FILTER: The producers recommend that filters be changes at least once or twice a year, at the beginning and end of the heating season.
DISPOSAL: The used filter is disposed of alongside normal household waste.
WHY CHANGE FILTERS OVER TIME?
* Old and dirty filters lead to a pressure drop in the ventilation system and, as a result, the volume of fresh air inflow decreases, which worsens the indoor climate.
* An old, dirty filter can contribute to the spread of mould in the ventilation system. (especially in humid climates), which can be a health hazard.
* The new filter has the best air permeability levels and, as a result, savings can be made in electricity costs for the fan unit.
