Are bladeless DC-motor tower fans like DREO and LEVOIT worth it over a cheaper AC fan?

For most bedroom and home-office buyers the consensus across verified-purchase and community reviewers is yes: DC-motor models from DREO and LEVOIT are repeatedly described as quieter at low speeds and more efficient, with several r/fans and r/BuyItForLife posters calling them noticeably stronger than older Lasko units. The tradeoff is that even DC fans get loud at maximum speed because of the small column-style blade, a point raised in multiple BuyItForLife threads.
