Frequently asked questions
Are these original Orcon parts?
No. They are compatible filters, made to the dimensions of the HRC 400 filter (185 × 560 × 23 mm) and to the stated filtration class. The manufacturer is a European producer of ventilation filters.
G4/G4 or G4/F7: which set for the HRC 400?
G4/G4 keeps the standard configuration: one fine-coarse filter on each side. G4/F7 puts a fine filter (ISO ePM1 65%) on the supply side, useful against pollen and fine particles, and keeps the G4 on the extract side. The F7 loads up faster: keep an eye on it.
How do I know the filter will fit my unit?
Compare the dimensions above with those of your current filter, and the frame type. The compatibility on this page comes from Revendeurs spécialisés (HRshop), septembre 2026.. If in doubt, write to us with a photo of the filter.
