Air filtration – Climate Control


Strategies to maximize safety during the COVID-19 pandemic and the continued reopening of schools, restaurants and other public spaces continue to evolve around the world.

Airborne transmission of the virus has been widely identified as the main route of transmission. Therefore, implementing new technologies to meet this new indoor air quality (IAQ) challenge is a top priority as Australia navigates the ‘new normal’.

The Purafil PuraWard Air Filter is an ideal solution for the safe and efficient removal of airborne microbial contaminants.

Available in various sizes and particle filtration grades, PuraWard filters are made from specialized polymer fibers engineered with an antimicrobial agent registered by the US EPA. The additive provides silver and copper ions which synergistically inactivate microorganisms through disruption of cellular respiration, inhibition of intercellular transport, structural degradation of viral protein envelopes, and other pathways.

Unlike filtration materials which are sprayed or otherwise treated with similar additives, antimicrobial ion carriers are built into the PuraWard fibers (pictured).

This prevents the potential leaching of chemicals into the air streams, ensuring safe and clean elution air streams where filters are used.

Alternative air purification systems based on ionization, photocatalysis and other electronic technologies are also advertising antimicrobial claims. However, studies around these technologies have shown that these systems exhibit varying efficiencies in end use.

These systems present the risk of generating potentially harmful contaminants such as ozone and formaldehyde – which can create even more serious health complications for the inhabitants of the treated spaces. Because PuraWard relies on well-established, non-hazardous filtration technology, there is no risk of eluting harmful byproducts.

Unlike many other manufacturers of air purification devices, Purafil offers third party microbial efficacy data on demand to end users, which confirms the materials claims on the removal of biological contaminants. potentially harmful.

PuraWard filter media is available in a pleated form for use in “Vee-Form” filters or can be supplied in a bag filter configuration. This means that existing sites can be easily upgraded to PuraWard media with no new storage frames or additional work required.

In the case of the Vee-Form filter, simply replace your existing filters for enhanced PuraWard safety and protection. For pocket filters, Puraward can be offered in En: 779 F8 efficiency and in industry standard sizes. This allows customers to add this advanced level of protection to their site immediately by replacing their filters.
