At 5 PSI maybe 5-10 minutes worst case. You can run the pressure notably higher without damaging the filter but doing so results in more foaming of the beer. At some amount of pressure the filter could in theory collapse in on its self but I feel that would me a great deal more pressure then is practical to apply. The foaming is very minimal at 5 psi and in honestly since its a CO2 environment the foaming and distributed prolonged contact with CO2 if anything just helps the beer absorb the CO2 into the beer and thus quickens your force carbonation.
