Mazda recommends replacing the fuel filter every two years or 30,000 miles, whichever comes first
Some sources suggest that the fuel filter should be replaced every 25,000 miles, while others state that it should be replaced every 60,000 miles. However, it is important to note that this may depend on the quality of the fuel being used. If you are filling up your tank with fuel from shady, third-rate gas stations with rusty tanks, you may need to replace your fuel filter more often. If your engine is sputtering due to fuel starvation, this could be a sign that you need to replace your filter.
It is always a good idea to refer to your owner's manual for specific recommendations on how often to replace the fuel filter in your Mazda. Dealerships can also provide guidance on fuel filter replacement and other scheduled maintenance tasks.

Some sources say the fuel filter should be replaced every 25,000 miles
One user suggests that the fuel filter should be replaced every 30,000 miles or two years, whichever comes first. Another forum user suggests that the fuel filter should be replaced every 60,000 miles, as stated in the owner's manual.
It is worth noting that some forum users suggest that the need to replace fuel filters is decreasing. This is because modern fuel tanks are made of plastic, so rust is less prevalent, and fuel is cleaner. Additionally, fuel pumps house a screen filter to eradicate large debris, followed by a 'lifetime filter'.

Modern cars have plastic fuel tanks, so rust is less prevalent
Mazda owners are recommended to replace their fuel filter every two years or 30,000 miles, whichever comes first. However, modern cars have plastic fuel tanks, so rust is less prevalent. This means that fuel is cleaner and the need to filter gas is less than it used to be. Some cars still have fuel filters, but the necessity to change a filter every 100,000 miles goes to show the extremely low need to require it considering the amount of gas that passes through the system in that time frame.
Mazda dealerships replace fuel filters all the time as part of scheduled maintenance. If you look in your owner's manual, it tells you to replace the filter every 60,000 miles. However, unless you are filling up your tank at some really shady third-rate gas stations with rusty tanks on a regular basis, there really isn't any need to replace a fuel filter. If for some reason your engine is sputtering due to fuel starvation, then maybe you should replace your filter and stop filling up at shady, rusty tank gas stations.

If your engine is sputtering due to fuel starvation, you should replace your filter
Mazda recommends that you replace your fuel filter every two years or 30,000 miles, whichever comes first. However, some sources suggest that this is unnecessary unless you are filling up your tank at low-quality gas stations with rusty tanks. If your engine is sputtering due to fuel starvation, you should replace your filter and stop filling up at these stations.
Mazda dealerships replace fuel filters as part of scheduled maintenance. If you look in your owner's manual, it will tell you to replace the filter every 60,000 miles. However, some older cars with metal fuel tanks may require this to be done more often, as rust is more prevalent. Nowadays, fuel tanks are made of plastic, so rust is less of an issue. Additionally, fuel is cleaner, and fuel pumps house a screen filter to remove large debris, followed by a "lifetime filter".
Some cars still have fuel filters, but the necessity to change them is extremely low. For example, one source suggests that you would only need to change the filter every 100,000 miles. Another source suggests that you would have to have really horrible fuel quality to justify changing a fuel filter every two years or 25,000 miles. Diesel vehicles are an exception, as their filters may need to be changed more often due to rust.
