Investigation summary when the airtightness of the actual product was checked (the relevant jis standard: 150kpa for 15 minutes, there was no water leakage when pressurized), liquid leakage was observed from the filter part (lower part).Therefore, we asked the filter manufacturer and distributor to investigate the material.According to the results of a survey by the filter manufacturer, the leak was caused by a crack in the upper vent membrane of the filter.The hydrophilic film on the side was also broken.Upon review of all production records, no nonconformance records were found.Based on the damaged state of the actual membrane, it was presumed that excessive back pressure was applied from the lower part of the filter, resulting in damage to the membrane and leakage.When injecting from the lower side of the filter, the user must be sure to close the clamp at the bottom of the filter so that there is no back pressure that may cause the filter to peel off.If any abnormality such as liquid leakage is detected, the user should stop using the product and replace it with a new product.No anomaly found on dhr.
