Patent Issued for Innovative, Energy-Efficient Air Filtration Technology Licensed to Agentis Air

Patented Advanced Particle Removal Technology (APART) can remove airborne pollution — including viruses — while using less energy and with lower maintenance costs than other filtration technology.

The US Patent and Trademark Office this month issued a patent to the University of Washington (UW) for a new form of high-capacity, energy-efficient air filtration, developed at the UW Sensors, Energy, and Automation Laboratory. Exclusive, worldwide licensee Agentis Air, LLC sees APART as a foundational technology for a new generation of energy-efficient purification devices and as an adaptation for current or legacy systems.

  • The patented Advanced Particle Removal Technology (APART)—in which charged particle-repelling plates are paired with disposable, foam-encased, charged particle-collecting plates—is the result of five years of research at The University of Washington’s Sensors, Energy, and Automation Laboratory.
  • Current concerns about airborne disease—including controlling indoor air quality and protecting respiratory health—underscore the timely value of the technology to remove airborne viruses and reduce particulate-borne aerosol transmission.

The design, in which particle-repelling plates are paired with disposable, foam-encased, particle-collecting plates, can be used in air purification and HVAC design applications for commercial and consumer markets. The technology covered in US Patent No. 10,668,483 was developed under the direction of Igor Krichtafovitch, PhD, an expert in electrostatics and particle pollution reduction. Dr. Krichtafovitch is the Director of Research and Development at Agentis Air, LLC, the exclusive worldwide licensee of the technology.

“Dr. Krichtafovitch and Agentis Air have been working closely with UW’s CoMotion innovation hub for several years to develop this technology and to build a patent portfolio so the technology can be brought to market. We are excited about the patent and the numerous energy-saving commercial filtration applications that this foundational technology may enable,” notes Larry Rothenberg, Agentis Air president.

Indoor air quality has long been linked to a growing number of life-shortening diseases—including respiratory ailments, heart disease, and dementia. With recent public health concerns, the ability of APART-enabled air purification devices and systems to remove virus particles underscores the importance of this technology.

APART has several advantages over existing filter-media technologies, notably the ability to substantially reduce back-pressure and energy use. Unlike mechanical HEPA-style systems (which rely on pass-through filtration), there is no filter to clog, so airflow is improved for lower energy use, lower cost, and quieter operation; The APART collection media has a longer life, as well.

A significant advantage for commercial applications, APART is the first filtration system capable of smart control, offering the ability to increase or decrease system filtration levels and energy use on demand. This smart-control feature is designed to take advantage of advances in IoT and sensor technology so filtration can be monitored and adjusted in real time.

The patented technology overcomes the limitations of traditional Electrostatic Precipitator (ESP) systems: APART eliminates manual cleaning, making it a commercially scalable, low labor-cost solution; Increased surface area improves effectiveness over traditional ESP, as does increased load capacity. The technology also reduces particle re-entry into the air and filters ozone.

Agentis Air, LLC is developing and marketing branded products and plans to partner with companies that can use the technology to improve the air-filtration capabilities of a wide range of products and systems. Potential applications include portable air purifiers, commercial HVAC systems, air exchangers, and dynamic air-filtration systems using sophisticated, building-control sensor data.
