A study by the Journal of Air Quality (2022) found that neglecting filter maintenance can reduce the purifier’s effectiveness by up to 50%. Regular maintenance ensures efficient operation and longevity.

4. Using it consistently: Operate the air purifier continuously, especially during peak pollution times like cooking or cleaning. The National Institutes of Health (NIH, 2023) recommends continuous use to reduce airborne contaminants and improve indoor air quality.

5. Keeping windows and doors closed: Close windows and doors while the air purifier operates to prevent outdoor pollutants from entering. According to research in the Indoor Air Journal (2021), doing so can significantly enhance indoor air quality and increase the purifier’s efficiency.

By following these guidelines, users can improve the efficiency and effectiveness of their home air purifiers.
