Welcome to NICO.
Make sure the battery connections are clean and tight. This is a common starting problem, even with new battery. You may also have stale fuel or worse, contaminated fuel. When you replaced the fuel filter, what's the color of the fuel that came out of the tank?
Another possibility is a weak/failing fuel pump (low fuel pressure) or bad fuel pressure regulator (fuel drains back into the tank when engine shuts down). Set ignition switch to ON and listen for fuel pump (in tank, behind rear seat). It should run for @ 5 seconds then shuts down automatically. Then start the car. If the car starts normally, you have a problem with fuel delivery. You need to check the fuel pressure as well as perform leakdown test to isolate the problem.
It would also help us if you could be more descriptive about the hard starting problem.
