Claim 0:
1. A bypass filter comprising:
a conduit comprising a conduit wall, the conduit wall defining a main passageway configured for passage of fluid from an upstream end of the conduit to a downstream end of the conduit;
a main filter located within the main passageway and configured for preventing passage therethrough of a predetermined substance within the fluid, while allowing a remainder of the fluid to pass towards the downstream end of the conduit, wherein the main filter blocks the main passageway to gases in response to a predetermined amount of water accumulating on an upstream surface of the main filter and prevents passage of the gases through the main filter,
wherein the conduit wall defines an upstream opening located upstream of the main filter and being in fluid communication with the main passageway at an upstream end of the conduit and a downstream opening located downstream of the main filter and being in fluid communication with the main passageway at a downstream end of the conduit; and
an auxiliary filter extending between a first auxiliary filter end and a second auxiliary filter end, the auxiliary filter being in fluid communication with both the upstream opening and the downstream opening, wherein the auxiliary filter is configured to enable the fluid to pass between the upstream opening and the downstream opening while at least partially absorbing the substance,
wherein the main filter is located within the main passageway at a position between the first auxiliary filter end and the second auxiliary filter end, and wherein the bypass filter diverts fluid to travel from the upstream end of the conduit to the downstream end of the conduit via passage through the auxiliary filter when the main passageway is blocked.
