The correlation between the invisible Higgs decay width vs. DM direct decetion in Higgs portal DM models is usually presented in the effective field theory approach. This is fine for singlet scalar DM, but not in the singlet fermion or vector DM with Higgs portal. In this talk, I recapitulate the UV completions of the singlet fermion DM and vector DM with Higgs portal, and show that there are hidden parameters, the additional singlet scalar mass and its mixing angle with the SM Higgs boson. I show the correct form of the upper bounds on DM direct detection cross sections derived from the invisible Higgs decay width.
