Size NoticeOur replacement filter is specially designed for the VOOPNU JH12 air purifier and measures 5.12in × 5.12in × 3.62in, identical to the original filter included with the unit. A tolerance of about ±0.04in (1mm) may occur, but this does not affect performance. After installation, you may notice a small gap between the filter and the frame—this design helps guide airflow through the filter core, enhancing purification efficiency
