The US Patent and Trademark Office (USPTO) has quite recently issued a patent to the University of Washington (a public research university in Seattle, Washington, founded in 1861) for a new form of energy-efficient and high-capacity air filtration technology developed at the UW Sensors, Energy, and Automation Laboratory.

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

The indoor air quality has been linked to an increasing number of life-shortening diseases, such as heart diseases, respiratory ailments, and dementia, for quite a while now. Keeping in mind the recent public health concerns, the enhanced ability of Advanced Particle Removal Technology (APART)-enabled air purification systems and devices for removing the virus particles – underscores the importance of this technology.

APART has multiple advantages over the already existing filter-media technologies like HEPA filtration, notably the ability to reduce the backpressure and energy use substantially. Unlike mechanical HEPA-style filtration, there isn’t any filter to clog; hence, the airflow is improved for quieter operation, lower cost, and lower energy use. APART is also the first filtration system, which is capable of smart control and offering the ability to increase or decrease the energy use and system filtration levels on demand. The smart control feature can be designed to take advantage of advances in sensor technology and the internet of technology so that the filtration can be monitored and adjusted in real-time.

The patented technology efficiently overcomes the limitations of traditional Electrostatic Precipitator (ESP) systems – APART eliminates the need for manual cleaning, which makes it a low labor-cost, commercially scalable solution. The increased surface area and load capacity improve the overall effectiveness over traditional ESP. The technology also minimizes particle re-entry into the air and filter zone. Potential applications of the technology include commercial HVAC systems, portable air purifiers, and air exchangers and dynamic air-filtration systems using sophisticated, building-control sensor data.
