An air cleaner device for filtering intake air including a housing defining a chamber, a filter element disposed within the chamber, and a duct element having a passageway in fluid communication with the chamber. Further, the duct element extends along and downwardly from about a portion of the housing and further includes an inlet for drawing intake air into the chamber. The air cleaner having a base member in fluid communication with the chamber and an outlet, where the air drawn into the chamber is filtered by first and second filtering operations to obtain filtered air, with the first and the second filtering operations accomplished at least in part due to a cyclonic motion of the air and passage of the air through the filter element, respectively; and where the filtered air from the chamber of the housing is released through the outlet in the base member.

1. An air cleaner comprising: a housing defining a chamber therewithin;a filter element disposed within the chamber of the housing;a duct element having a passageway in fluid communication with the chamber of the housing, the duct element extending along and downwardly from about a top portion of the housing, the duct element further comprising an inlet for drawing intake air into the chamber; anda base member in fluid communication with the chamber of the housing and having an outlet, the base member for releasably securing a bottom portion of the housing thereto;wherein the air drawn into the chamber of the housing is filtered by first and second filtering operations to obtain filtered air, the first and the second filtering operations accomplished at least in part due to a cyclonic motion of the air and passage of the air through the filter element, respectively; andwherein the filtered air from the chamber of the housing is released through the outlet in the base member. 2. The air cleaner of claim 1, wherein the base member comprises a first portion that is in fluid communication with the chamber of the housing, and comprises a second portion having the outlet and in fluid communication with the first portion, and wherein the first filtering operation results in removal of heavier particulate matter from the intake air. 3. The air cleaner of claim 2, wherein, due to the cyclonic motion of the intake air, at least some of the heavier particulate matter moves outwardly and downwardly within the chamber towards the base for collection, the downward motion of the particulate matter aided at least in part by gravity. 4. The air cleaner of claim 3, wherein the second filtering operation causes removal of finer particulate matter from the intake air. 5. The air cleaner of claim 1, wherein the second filtering operation causes removal of finer particulate matter from the intake air. 6. An air cleaner comprising: a housing having a top portion and a bottom portion and having a chamber therewithin;a filter element disposed within the chamber of the housing;a duct element having a passageway in fluid communication with the chamber of the housing, and having an inlet for drawing intake air into the chamber;a base member for releasably securing the bottom portion of the housing thereto, the base member comprising a first portion in fluid communication with the chamber of the housing, and a second portion having an outlet and in fluid communication with the first portion. 7. The air cleaner of claim 6, wherein the intake air is drawn into the chamber of the housing through the inlet of the duct element and the duct element passageway and a cyclonic motion is imparted to the intake air. 8. The air cleaner of claim 6, wherein a first filtering operation is facilitated at least in part due to a cyclonic motion imparted to the intake air and a second filtering operation is facilitated by flowing at least a second portion of the intake air through the filter element, the first and the second filtering operations for separating particulate matter from the intake air to obtain filtered air. 9. The air cleaner of claim 8, wherein the first filtering operation results in removal of heavier particulate matter from the intake air; wherein the second filtering operation causes removal of finer particulate matter from the intake air; andwherein the heavier particulate matter is heavier than the finer particulate matter. 10. The air cleaner of claim 9, wherein due to the cyclonic motion of the intake air, at least some of the heavier particulate matter moves outwardly and downwardly within the chamber towards the base for collection, the downward motion of the particulate matter aided at least in part by gravity. 11. The air cleaner of claim 9, wherein the intake air is subjected to the first filtering operation before being subjected to the second filtering operation. 12. The air cleaner of claim 6, wherein the first portion of the base further comprises a collection portion for collecting a separated particulate matter from the intake air and having an opening for removal of the collected particulate matter. 13. The air cleaner of claim 6, wherein the inlet duct is positioned towards a cool air engine location for operating environments having a moderate to high ambient temperature. 14. The air cleaner of claim 6, wherein the inlet duct is positioned towards a warm air engine location for operating environments having a low ambient temperature. 15. The air cleaner of claim 6, further comprising a flange member disposed within the chamber of the housing. 16. The air cleaner of claim 15, wherein the flange member is positioned and configured to deflect at least a portion of the intake air into the cyclonic motion. 17. The air cleaner of claim 15, wherein the housing includes a housing main portion that comprises an inner wall portion and an outward wall portion that are connected, at least in part, by the flange member. 18. An internal combustion engine comprising: a muffler; andan air cleaner, the air cleaner comprising: a housing having a top portion and a bottom portion and having a chamber therewithin;a filter element disposed within the chamber of the housing;a duct element having a passageway in fluid communication with the chamber of the housing, and having an inlet for drawing intake air into the chamber;a base member for releasably securing the bottom portion of the housing thereto, the base member comprising a first portion in fluid communication with the chamber of the housing, and a second portion having an outlet and in fluid communication with the first portion. 19. The internal combustion engine of claim 18, wherein the intake air is drawn into the chamber of the housing through the inlet of the duct element and the duct element passageway and a cyclonic motion is imparted to the intake air. 20. The internal combustion engine of claim 18, wherein a first filtering operation is facilitated at least in part due to the cyclonic motion of the intake air and a second filtering operation is facilitated by flowing at least a second portion of the intake air through the filter element, the first and the second filtering operations for separating particulate matter from the intake air to obtain filtered air.
