How to filter words that contain atleast 2 vowels from a series?

# Input
ser = pd.Series(['Apple', 'Orange', 'Plan', 'Python', 'Money'])

# Solution
from collections import Counter
mask = ser.map(lambda x: sum([Counter(x.lower()).get(i, 0) for i in list('aeiou')]) >= 2)
ser[mask]

# output
0     Apple
1    Orange
4     Money
