This premium supply air filter for the ventilation system Drexel & Weiss x² S3/S5/S7/S9 is suitable for users who have the highest demands on the indoor air quality of their home. With its well-thought-out design, high-quality workmanship, and excellent filtration properties, it even surpasses the filters supplied by the device manufacturer itself. After installing this filter, up to 85% of fine dust can be separated, thus ensuring high-quality supply air. Thanks to the MiniPleat filter medium with fine pleating, a large filter surface area and low pressure loss are achieved. Therefore, this filter has no significant impact on the performance or power consumption of the Drexel & Weiss x² S3/S5/S7/S9 device when used in it.
