V. Traditional Misconceptions and Scientific Recommendations Misconception: Using tea leaves, pineapple, or other odor masking agents is merely a psychological aid and does not eliminate pollutants. Recommendations: Light pollution: Ventilation + activated carbon + plants combined; Moderate pollution: Photocatalyst spraying + regular ozone treatment; Severe pollution: Fresh air system + professional photocatalyst engineering treatment. Core Principle: Prioritize technologies that prevent secondary pollution and have long-lasting effects, combining active purification (such as fresh air and negative ions) with passive adsorption (such as activated carbon) to create a synergistic effect. VI. Pollution Warning and Action Guide Immediate professional testing is required if the following conditions occur: Morning nausea and dizziness, frequent colds or skin allergies in family members; Unexplained death of pets, wilting of plants, and persistent odors in newly renovated homes. Prompt intervention can prevent health risks such as decreased immunity and reproductive system damage caused by pollutants such as formaldehyde and benzene. https://www.renkeer.com/indoor-air-quality/
