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. For view
