RESPA Filtration Program: Standards & Ratings

Sy-Klone is serious about air quality in operator enclosures. RadialSHIELD® filters provide 100% seal integrity. Sy-Klone's patented MERV 16/F9 filter (minimum level of filtration recommended by NIOSH) uses unique nano technology which provides dramatically extended filter life. Sy-Klone's 200-series HEPA filters are ISO 23875 compliant and can filter COVID-19-size particles. Not only does your operator breath easier, but HVAC systems stay clean and healthy as well! Read more about MERV vs. HEPA and how air filters work.

IMPORTANT NOTES:

It is important that you select the RESPA Filter that best fits your application.

MERV is an acronym for "Minimum Efficiency Reporting Value". The MERV rating on an air filter describes its efficiency as a means of reducing the level of 3 to 10 micron-sized particles in air which passes through the filter. Higher "MERV" means higher filter efficiency. The purpose of the MERV standard is to permit an "apples to apples" comparison of the filtering efficiency of various air filters. <Read more about MERV and HEPA filter ratings>

HEPA air filters are not MERV rated as they exceed the ASHRAE test protocol 52.2 used in determining the MERV ratings. In fact, HEPA air filters are the ONLY mechanical air filters that are tested and certified to meet a specific efficiency at a specific particle size. All HEPA air filters must meet a minimum efficiency of 99.97% at 0.3 microns. <Read more about MERV and HEPA filter ratings>

Comparison of EU Standards to ASHRAE 52.1, 52.2 (MERV Ratings)
Considerable differences exist between filter ratings in North America and Europe. This article helps the reader to understand the differences between ASHREA and EU standards for Filtration. Additional light is shed on the significant differences in the HEPA filtration standards between the US Government and the European standards. This article will help the reader to appreciate the filtration offered by Sy-Klone International. <Read more about European filter standards and how they compare to MERV ratings>
