JSP says its Filterspec unit, which combines a mask and disposable filterrnwith safety spectacles, allows both protective devices to workrnindependently, but in harmony.rnWearing safety spectacles with a mask can be uncomfortable andrnimpractical, says the manufacturer, and leakage can occur, resulting inrnmisted lenses and reduced respiratory protection. Filterspec is said to allow both protective devices to work at their full effectiveness, but as an integrated single unit. The wrap-around one-piece lens features anti-mist and anti-scratch coatings as standard, while the mask holder and filter, which incorporates an exhalation valve for comfort and longer filter life, weighs less thanrn60g, says JSP. The initial unit is sold with three replacement masks withrnreplacement filters sold separately in boxes of 10.
