Abstract
An air filtration apparatus for supplying a flow of filtered air to an inlet of an RPT device, the air filtration apparatus comprising an inlet flow path, an outlet flow path, an air outlet, and a blower configured to receive air from the inlet flow path and to supply air at above ambient pressure to the outlet flow path, wherein the inlet flow path comprises a filter means comprising a HEPA filter and/or a VOC filter, and wherein the blower is configured to supply pressurised air to the outlet flow path at a flow rate of at least 5 L/min.
Claims11
A system for providing air to a patient at positive pressure for respiratory therapy, the system comprising:
- an air filtration apparatus comprising a HEPA filter and/or a VOC filter, and a first blower;
- and
- a respiratory pressure therapy (RPT) device comprising a second blower;
- wherein an air outlet of the air filtration apparatus is located relative to an air inlet of the RPT device such that the air inlet of the RPT device receives filtered air from the air outlet of the air filtration apparatus;
- wherein the air filtration apparatus is configured to define a bypass flow path which allows ambient air to flow to the air inlet of the RPT device without passing through the first blower;
- and
- wherein the RPT device has a predetermined shape around the air inlet, and where a housing of the air filtration apparatus is shaped and configured to define the bypass flow path between an outer surface of the housing surrounding the air outlet of the air filtration apparatus and the air inlet of the RPT device.
