- Model RU8500 - Half Mask



Improve productivity and maintain compliance with the Honeywell North® RU8500 Series half mask. The RU8500 is one of the only reusable half masks on the market with a speech diaphragm. This feature offers improved speech clarity – eliminating the need for workers to leave the work space or doff the mask in order to communicate. Made from soft, flexible silicone, the RU8500 provides workers with a comfortable fit for hours of use while the dual sealing flange provides an excellent facepiece seal. The RU8500 also has the unique option of a diverter exhalation valve cover, which directs exhaled breath downward and is ideal for painting/coating/sealing. Available in royal blue, light green and lilac.
