This invention relates to a concealed cistern comprising the odour remove system to vacuum and filter the odour inside the bowl. The odour removing system, containing a fan and an air-cleaning filter is installed in a ventilating box. The ventilating box is covered by a protection box and installed on the fitting tube and said fitting tube is attached to the overflow tube of the standard flush mechanism. The fan blows the unfiltered vacuumed air to the filter; the odour air passes through the filter and leaves the concealed cistern passing through the slots provided on the both sides of panel cover. |
