The manual emphasizes using distilled or demineralized water to reduce mineral deposit build-up and white dust—an important, practical recommendation. One potential shortcoming is limited explanation of health risks from improper maintenance (e.g., how bacteria or mold aerosols can aggravate respiratory conditions); a brief, plain-language explanation could motivate regular cleaning.
