Filter re-calibration is available from EMS and if not regulated by EPA regulations in your State to a more
frequent schedule we suggest you re-calibrate at the minimum of once a year. If you have filters from other
manufacturers we can also calibrate them as well (call for pricing). Filters are tested per USA Code of Federal
Regulations 40CFR60 Appx. B, Performance Specification 1, Section 7.1.3 Attenuation Calibration.
