All of our particulate respirators have been approved by the Japanese Ministry of Health, Labour and Welfare.Formidable DustParticle FilterParticle FilterFilter Replacement CriteriaGas FilterGas FilterMechanical Filter•Replace the filter with a new one when you have difficulty in breathing due to clogging from particle accumulation.Electrostatic Filter•Replace the filter with a new one when you have difficulty in breathing due to clogging from particle accumulation.•Replace the filter with a new one after a certain period of use determined beforehand.Dispose the filter per every use in atmospheres such as arsenic, chromium etc.*In accordance with "Choosing and Usage of Particulate Respirators" (Notice of the Japanese Ministry of Health, Labour and Welfare Division Labour Standards Bureau No.0207006 of February 7, 2005) .① When the accumulated record of used time reaches the predetermined breakthrough time.② When the weight of the used gas filter increases due to moisture or absorption of airborne contaminants. (Can not be applied for moistureproof-type gas filter)③ When a wearer smells contaminants or feels irritant.④ Gas filters for methanol shall be disposed after one-time use.⑤ For combined filters, when inhalation resistance increases and breathing is difficult even if the accumulated record of used time has not reached the predetermined breakthrough time.*The above criteria are not exhaustive, please use the proper criterion or several criteria depending on the situation of the work site.
