Pandas Series filtering: Chaining loc for multiple conditions

My favorite way to apply multiple filters to a Python Pandas series? Method chaining calling loc 2x:

s = pd.Series([10, 15, 20, 25, 30])

(
  s
 .loc[ (s > 20)]       # filters s
 .loc[ (s % 2 == 1) ]  # filters line 1
)

But: This can break! Tomorrow, a better way.
