Ozone Generator Recommendations Please

[Wilson Churchill]

A house I recently purchased has a cat odor in one room that is lingering after being painted. Another has a strong mold smell. I am looking for a strong ozone generator that would be sufficient to:

1. Remove pet odors

2. Supplement mold remediation by reaching areas that can't be easily treated or painted

This one looks interesting, but I don't know which models would be sufficient:
