This study developed a compact and portable in-situ He neutron spin filter ( He NSF) utilizing spin-exchange optical pumping at MLF of J-PARC. Its performance as an incident neutron polarizer was evaluated at MLF, where it achieved a He polarization exceeding 0.6, corresponding to a neutron polarization greater than 0.8 at 1.8 
. Notably, the He NSF demonstrated stable operation for 110 h. These outcomes signify that the developed in-situ He NSF facilitates and promotes polarized pulsed neutron experiments at MLF.
