This pre-assembled Moldex 7000 series respirator arrives conveniently ready to go to save time wasted selecting and attaching the proper filter. This 7000 series half mask respirator arrives with two P100 filter disks. Encased in a durable plastic ring, the P100 filter disk is able to withstand rough handling. It is NIOSH certified for an efficiency level of 99.97% against both oil and non-oil based particulates. It is ideal for environments with contaminants for which OSHA requires a High Efficiency Particulate Air (HEPA) filter, such as asbestos, lead, inorganic arsenic and cadmium. A lightweight face mask ensures a comfortable fit all shift long. It is also compact, so it stays out of the way and allows for a wider field of vision.
