Zentek completes case study on HVAC total cost of ownership savings

Zentek has completed a case study based on the City of Toronto highlighting the economic and environmental benefits related to using MERV 9A filters compared to using MERV 13 filters. The study quantifies cost savings and reductions in carbon emission and waste assuming the City of Toronto is currently using MERV 13 filters in all its buildings and switches to MERV 9A filters. Key Findings: Annual cost savings of over $40 million from: Significantly reduced labour costs due to filters being changed every six months rather than every three months; Reduced expenditures on air filters from replacing filters every six months rather than every three months; Reduced energy requirements and costs due to improved air flow; Lower waste disposal costs from fewer filters being used; Reduced energy requirements and associated carbon emissions of 3,029 tonnes of CO 2 equivalent – an amount that takes 49,976 newly planted tree seedlings growing for 10 years to absorb; Reduced landfill waste by ~947 full dumpsters.
