The AORA specification is Coarse 65% for the G4 filter and ePM1 60% for the F7 filter. The original FR\u00c4NKISCHE set is specified as Coarse 75% and ePM1 70%, so the ISO efficiencies differ despite the shared former classes.<\/p>\n<h2>Use and maintenance<\/h2>\n<p>Inspect the filters regularly and replace them approximately every 3\u20136 months, or sooner if they are dirty or clogged, or if the unit&#8217;s filter alarm indicates it. The interval depends on dust exposure and operating conditions. Switch off the unit before maintenance, follow its manual, and install each filter in the correct air path, observing the airflow arrows. These filters are not designed to be washed.<\/p>\n<h2>Manufacturing quality<\/h2>\n<p>Our house-brand filters are manufactured by AORA, a reputable and well-known filter manufacturer. The G4 filter uses Z-line technology and the F7 filter uses Minipleat technology with closely spaced pleats. Both filters have 2xU synthetic frames, as specified for this product. The complete set is supplied with a box.
