best way to delete breaths in track

Using Audacity 2.1.1 on MAC OS High Sierra 10.13.3

General question - I just cut out the breath sounds on recording using the edit tool is there a better way to do this? I sometimes cannot select the entire breath sound. Should I use Noise Reduction effect if you can capture the whole thing?

Thanks for your advice

There are de-breath plugins which reduce/remove all breath sounds in one pass. They are noise gates.

Definitely not for de-breath.
