COVID-19 pandemic highlighted the need for a healthier and safer indoor environment. This includes better filtration to remove aerosol-size ultrafine particles, more frequent air exchanges, and the need for air disinfection. High-efficiency filters, recommended to improve indoor air quality (IAQ), come with higher-pressure drop, leading to an increase in power consumption and reduce the efforts to make buildings more energy-efficient. Bringing more outdoor air increases the load on the cooling system, resulting in higher energy use by HVAC.
This technology addresses the limitations of existing air cleaning methods by enabling the highest filtration efficiency on the system level (in the range of 98.00-99.99% @ 0.3μm) at the pressure drop equivalent to a MERV 8 filter (0.27”). Such a small pressure drop helps reduce energy consumption required for air filtration by 50-70%, compared to commonly accepted MERV 13-15 and HEPA-rated filters. A constant high-energy field creates a self-contained, highly ionized state in the filter that aggregates and effectively capture ultrafine particles (down to 0.007μm). The same high-energy field deactivates microorganisms, including viruses, and prevents them from growing inside the filter.
The technology owner is seeking partnerships with Singapore-based companies to jointly pilot this filtration method in operational settings to verify the system’s performance in the tropical environment and collect data related to air quality, energy-saving and life cycle costs.
The technology owner is also keen to work with partners seeking to develop and customize their filtration system for specific use cases (e.g. second-hand smoke filtration, creating micro-environments, real-time reporting, etc.)
The features and specifications of the electrically enhanced filtration technology are as follows:
