Zwischen dem Lufteintrittssieb und dem den ganzen Filtertopf bedeckenden Beutel wird( ein mit Löchern versehener Abstandsring angeordnet; der nur von dem Beutel festgehabten wird und daher gemeinsem mit .dem Beutel auf das Filtergdhünse aufgesetzt «erden muß. Hierbei kommt es vor, dia.ß sich der Abs;Uandisrihg im Beutel verschiebt und- d'aß dhduzch nicht die richtige Anlage seines Endflansches am Eintrittssieb des Filters zustande kommt. Diies,er Nachteil wird gemäß der Erfindung dia- durch vermieden, daß ider am Filterdeckel anliegende Endflansch des Abstandsringes von einem offenen ' Federring festgefhalten ist, der mit an ihm an- geformten hakenförmigen Ansätzen in die Luftein- tribtfisÖffnungen des Filters eingreift. Die Zeichnung zeugt ein Ausfü hrunggbespiel des - Erfindünigsigegenstandes. - , Ablb. z stellt ein Atemschutzfilter mit festgeleg- tem Abstandsring im Schnitt dar, und Abb. z zeigt dem:. fodernden Haltering in sch-azu- biidl@ic'her Darstellung. Der Fütertopf i 'ist mit dem Siebdeck e1 2 verschlossen,. Unter ihm liegt die mit einem feinen Decksieb 3 abgedeckte Filtermasse.
