TargetFilter double check this for me?

Would this work correctly?:

local mouse = game:GetService("Players").LocalPlayer:GetMouse()
mouse.TargetFilter = game.Workspace["Bench Walls"],game.Workspace["Bench Walls2"],game.Workspace.Surround

If not, how else would I do that. ALSO where do I put the TargetFilter script? In starterplayerscripts?
