Purafil Solutions to Corrosion & Odour Problems

Airborne molecular contaminants damage electronics, circuit boards, and components.

The damage from corrosion can cause downtime in production, costly repairs, equipment failure and complete replacement in worst-case scenarios. Unpleasant odours can be a problem almost anywhere. Using Purafil media and equipment can help you eliminate unwanted odours and create a more comfortable, healthy environment.

Introducing ISO 10121-3

This is the first ISO Classification System for the gas-phase air filtration of outdoor air.

What is ISO 10121-3?

The world has quickly become aware of the importance for gas phase air filtration in even general filtration applications, due to increased pollution and increased understanding of its impact. The need for a standardized testing procedure to help non-technical end users understand gas phase filtration performance has lead to the creation of ISO 10121-3.

“ISO 10121-3 provides a classification system for the specific application of GPACDs [gas-phase air cleaning devices] in general, ventilation systems for cleaning of outdoor air polluted by local urban sources and/or long-range transboundary air pollution”.*

This standard specifies four test gases (ozone, sulphur dioxide, nitrogen dioxide and toluene) to be used as representative of common pollutants in urban areas. It also uses four duty levels that are assigned based on the performance against each target gas.

Who is ISO 10121-3 for?

This standard is useful for any building owner, facility management engineer, design engineers or maintenance personnel for buildings bringing in outside air in urban environments who are looking to evaluate gas phase filtration options for removing common air pollutants from local urban sources and/or long-distance pollution in a single pass. This does not cover recirculation air, or common indoor pollutants.
