Nissan says that because what you cleaned is not the fuel filter. That is the fuel pump pickup. It has a rough mesh to prevent large debris from entering the pump which could damage it or jam it.
The fuel filter is insert molded into the fuel pump module. If you notice how your fuel pump has a black hose coming out the top of it, which then turns 180 degrees back down into the fuel pump module. That is the filter, and it cannot be replaced or serviced as you cannot open the molded housing.
Generally, you dont have to worry about that filter for a VERY long time.
The rule of thumb for fuel injected cars is to get about a 100 micron mesh before the fuel pump, to protect the pump. After the pump, you want a 10-40 micron mesh filter to protect the fuel injectors.
