I have 2017 NX200T. It's pass 20K miles. I'm thinking about replace air filter and cleaning MAF sensor. I'm reading about reset ECU by remove 5A fuse at ECU-B for about 10 min. in fuse box on front passenger side.
Is it the correct way to do it? Thank you for your advices.

You don't need to reset the ECU for that, just change and go. The LTFT's will adjust as you go (STFT's will take care of immediate differences) and better off probably starting from where they are now than scratch.

I agree with @no1SomeGuy, there's no need to reset your ECU for maintenance. Your ECU will notice the difference and adjust accordingly very quickly.
