OUR HVAC filters manufactured as per EN779, EN1822 & ISO16890 standards.
There are many types of HVAC filters available these days. Different countries follow different standards for classification. Minimum Efficiency Reporting Value (MERV) is assigned to the filter depending on the PSE (particle size efficiency). The best filters have lower pressure drop hence consequent lower fan energy needed, greater dust holding capacity fan energy requirements and fewer changes.
The following are the most common use are
• ASHRAE 52.2 :2012
• EN779:2012
• EN 1822:2011
• MIL 282:1956
• IEST RP
