Each of our patented 5 Point filters is individually serialized & tested to ensure they meet the US Government 99.97 @ .3 micron HEPA Standard required by OSHA, EPA & NIOSH regulations.
Models with Dual Stage Filtration have an additional filter on the motor exhaust to add an extra layer of protection. These models are an excellent choice when working with more hazardous materials like lead paint or asbestos.
All filters are individually tested to IEST RP CC007.3.
