Your turbo is just pointing out into the atmosphere?
You could just put a cone on it, but any system that sucks from the engine bay is going to be fairly warm, which reduces power, and also contaminated, so your compressor will become less and less efficient as the compressor wheel is slowly damaged... never mind the damage you will get running dust through the engine/valves/turbo turbine at the other end.
A cone will be better than nothing, but with a cone or any foam type filter, they do need cleaning and oiling MORE often than you would change a paper filter, in order to achieve good filtration quality.
You are running a Td though, whose intake system is less than optimal... the HDi one is very good hence me suggesting not to run something else unless it is known to be excellent (nothing I have seen bar the BMC carbon thing piped straight onto the intake trumpet from the MAF sensor comes close)
