hot start

Normally (mostly) a dirty fuel filter will restrict the flow of fuel. So the signs of dirty one one is....the car will start and run OK up till a certain RPM, then it will start cutting out (misfiring). Dirtier ones will not allow the car to get up over a certain speed (like 50mph).

So the hard start when 'heat soaked' (as it is called) is not the filter.

Dirty injectors, carbon on the intake valves, a fuel system that won't hold the pressure after engine is off, a weak fuel pump (low pressure). These are the areas I'd be looking at if you came into the shop.
