1. Elektrostatisk filteranordning för rening av gaser med ett i ett filterhus (1, 10) i gasströmningsvägen infört svagt elektriskt ledande mikroporöst filtermedium (2, 11) och en anordning för alstring av ett elektrostatiskt högspänningsfält i gasens strömningsväg för ätminstone partiell jonisering av gasen före inträdet i filtermediet, varvid högspänningsfältets ena pol (5, 15, 20, 8, 9, 5^, 56, 6l, 3*1) Sr anordnad i gasströmningsriktningen före filtermediet (2, 11), och den andra polen (+, 55) är elektriskt förbunden med filtermediet, kännetecknad av att säsom mikroporöst filtermedium användes pä känt sätt ett aktivkolfilter (2, 11), tili vilken högspänningsalstrarens (3) den andra polen tillordnade ut-gängsklämma Sr direkt (galvaniskt) sä ansluten, att de frän den ena polen(5) utgäende elektrostatiska fältlinjerna väsentligen endast slutar i aktivkolfiltret, vars filterverksamma Stora inre yta därigenom bildar en med stor yta försedd andra samlings- resp. urladdningspol för det elektrostatiska högspänningsfält som joniserar den genomströmmande gasen.
2. Filteranordning enligt krav 1,kännetecknad av att den ena elektroden (5) Sr sä utformad, att det närmast med aktivkolfiltret (2, 11) befintliga ytomrädet bildar en skarp kant eller spets för att uppnä god jonisering av den genomströmmande gasen.
3. Filteranordning enligt krav 2,kännetecknad av att den ena elektroden (5, 15) Sr utformad som en näl, vars spets befinner sig intill filtret (2, 12),
4. Filteranordning enligt krav 2,kännetecknad av att den ena elektroden (15) bestär av flera nälar anordnade i ett pian som är ungefär vinkelrätt mot gasströmningsriktningen vid inträdet i aktivkolfiltret (2, 11), vilkas spetsar befinner sig pä ungefär samma avständ fr&n aktivkolfiltret, och att nälarna är elektriskt parallellt inkopplade.
