How long should a good tower fan last?

Verified-purchase reviewers commonly report 3–5 seasons of daily use before bearing noise, wobble, or motor wear show up; r/BuyItForLife threads single out Vornado for the longest service life, with multiple owners reporting 7+ years. Bladeless premium fans get more mixed longevity reports, with some r/dyson owners noting high-pitched noises emerging after roughly 18 months.
