Location of the temporary filter for secondary oil transfer at the engine oil station

Secondary oil transportation refers to the situation where, after the first test, the lubricating oil is found to be suitable for use in the bearing housing. In such cases, a filter is usually placed at the inlet to the bearings, that is, in the oil inlet pipeline of the bearing housing, which serves to protect the bearings. Additionally, it is also possible to check the particles in the filter
Once an oil leak test is successful, the lubricating oil should be considered clean. The oil is clean; is this filter still necessary?
It is still necessary to install a filter at the entrance of the bearing chamber; on one hand, this protects the bearings, and on the other hand, it allows for ongoing monitoring of the impurities accumulated on the filter

That is, during the second oil transfer, a temporary filter should be installed on the oil inlet pipe of the bearing box, and a temporary filter also needs to be kept on the main oil return pipe. Can it be understood this way?
The temporary filter for the secondary oil transfer in the compressor unit’s oil station should be placed in front of the bearing housing, as filtering the oil before it enters the bearing housing helps to remove any possible impurities and particles, thus protecting the bearings and preventing damage to them due to contamination. .
A filter screen is installed at the lubricating oil inlet for the bearings; no filter screen is needed for the return oil main pipe. There is an oil filter at the outlet of the oil pump, and when the pressure difference increases, it is sufficient to replace the filter element.
I believe a temporary filter should be installed on the return oil pipeline; if not, the secondary oil circulation will carry foreign particles from the bearing housing into the oil tank, causing contamination of the oil tank.
