Patented technology and solutions for better indoor air


Agentis Air is collaboration of research scientists, engineers, and air-quality experts on a mission to improve human health and longevity through better indoor air technology. We have decades of experience in university research and in commercializing clean air technologies for institutional, commercial, and consumer markets.

Our patented Advanced Particle Removal Technology (APART™) elevates effectiveness, reduces energy use, and eliminates maintenance. Developed over five at the University of Washington, our technology is designed for the next generation of indoor air quality solutions.

APART, used in our Brio™ air purifier, has several advantages over existing filter-media technologies. Unlike mechanical HEPA-style filtration, there is no filter to clog, so airflow and effectiveness stay high and maintenance costs are reduced.

In addition to portable air purifiers, APART technology has applications for commercial HVAC systems, air exchangers, and in air-filtration systems using our patented responsive-tuning technology paired with sophisticated, building-control sensor data.

  • Agentis Air introduces the Brio Air Purifier with patented technology to improve indoor air quality, overcoming HEPA limitations

    In commercial settings, Brio provides a rapid, adaptable response that closes the gap between building HVAC systems and healthy indoor air

    ROCKVILLE, Maryland, Friday, June 9, 2022—Return-to-work initiatives and the pandemic highlight the gap between the minimally acceptable indoor air quality in commercial spaces and truly healthy air. The system-level adaptations needed to achieve healthy indoor air are difficult to implement quickly and cost effectively. And after upgrades, HVAC systems may still fall short. For this reason, the EPA, the NIH, the CDC, and other advisory groups recommend the addition of in-room, portable air purifiers.

    Agentis Air closes the gap with the Brio portable air purifier. Brio serves as a first step, a supplement, and as an adaptable long-term solution to a dynamic health concern. Brio delivers constant, clean airflow for better indoor air quality without filter clogging. Designed for use in commercial offices, homes, and small-business establishments, Brio removes invisible fine and ultrafine particles, and kills viruses and germs, using patented Advanced Particle Removal Technology (APART™). Developed by researchers at the University of Washington, APART technology keeps Brio’s effectiveness high between cartridge replacements. Brio's non-clogging particle collection cartridge can last a year or longer.

    Brio’s Capabilities

    • Stays at peak effectiveness with no clogging
    • Traps fine and ultra-fine pollutants; Kills viruses, bacteria, and germs
    • Deep cleans 540 square feet in 20 minutes, 325 Square feet in 12 minutes
    • Low cost and zero-maintenance, using a disposable, high-capacity particle collection cartridge

    In discussing company’s motivation to create Brio, Agentis Air president Larry Rothenberg noted, “First and foremost, clean air matters to us personally, as we have experienced the effects of poor indoor air quality on long-term health. And second, thanks to our patented technology and expertise, we are in a unique position to create a more-advanced product than current market offerings. Unlike HEPA or PCO technology, Brio removes particulate matter while keeping the airflow high for better air purification.”

    Brio kills COVID-19 virus and removes other damaging fine and ultrafine particles

    In independent lab testing, at LMS Technologies in Minnesota, Brio removed 100% of live MS2 virus (Covid-19 surrogate) in just 15 minutes. Test conducted with LMS and at Intertek show rapid particle pollutant removal:

    • Covid-19 surrogate: Brio removes 100% in 15 minutes
    • Bacteria: Brio removes 99.9% in 20 minutes
    • Ultrafine Particles: Brio removes 100% in 23 minutes
    • Smoke: Brio removes 99% in 22 minutes
    • Dust: Brio removes 100% in 21 minutes
    • Pollen: Brio removes 96% in 10 minutes

    Better than HEPA

    All HEPA air purifiers—using technology little changed since its introduction almost 100 years ago—share the same limitation: as particles reach a HEPA filter, it clogs, reducing airflow. HEPA filters are efficient, but their effectiveness, measured by the Clean Air Delivery Rate (CADR), steadily declines with use.

    With airflow reduced, the air isn’t cleaned as quickly. Time compounds this problem, the air gets dirtier, and the HEPA air purifier falls behind in its task. HEPA air purifiers can't get around this clogging-and-declining-effectiveness problem. It's how they are designed to work. Blocking particles also blocks airflow.

    How Brio improves indoor air quality

    Rather than pushing air and particles into an increasingly clogged filter, Brio pulls particles away from the airflow. Brio’s powerful fan draws air in at the elevated base, and a pre-filter captures larger, visible pollutants. Next, viruses, germs, copier toner, smoke, dust, mold, pollen, and other particles too small to see, receive an electrostatic charge as they flow past Brio’s particle charger. The APART™ Collection Cartridge attracts and traps these charged particles, away from the airflow. With APART technology, the CADR stays constant over time, keeping the effectiveness high, until the long-life collection cartridge is completely full. Brio is UL listed and certified as ozone-safe by the California Air Resources Board (CARB).

    Affordability and Maintenance

    Brio’s APART Collection Cartridge can last 12 months or more, while staying at peak effectiveness. This gives Brio a more affordable cost-to-own profile than comparable HEPA-style air purifiers and significantly reduces maintenance. To stay at peak performance, a comparable HEPA air purifier may need three, four or five filter changes in the same amount of time. Over several years and with multiple air purifiers in an office, the cost difference and labor savings can be quite large.

    In performance tests—conducted under identical lab conditions for Brio and similarly sized HEPA and Photocatalytic (PCO) air purifiers—Brio never dropped below 90 percent of its original CADR. Brio also collected 60 grams of dust. Tested HEPA-style and PCO-style air purifiers in the same time period dropped to 50 percent of their original CADR performance and collected between 25 and 60 percent less particulate matter than Brio.

    APART Technology

    Patented Advanced Particle Removal Technology—which pairs particle-repelling plates with disposable particle-collecting plates—is the result of five years of research at The University of Washington’s Sensors, Energy, and Automation Laboratory. Igor Krichtafovitch, PhD, an expert in electrostatics and particle pollution reduction led the research. Dr. Krichtafovitch is the Director of Research and Development at Agentis Air, LLC, the exclusive worldwide licensee of the technology.

  • Brio, the Innovative Air Purifier
    Delivering constant clean airflow for peak effectiveness, patented Brio does what HEPA air purifiers can't. Brio removes ultrafine pollutants--viruses, germs, smoke, dust, mold, and more. Easy operation, low-cost-to-own, and minimal maintenance, too....

  • Close the Clean Air Gap Quickly with Brio

    Healthy indoor air at work is a baseline requirement yet meeting elevated clean air needs (and expectations) with existing systems can be a challenge. Attempts to adapt current systems may lead to increased inefficiency, higher energy usage, and more maintenance expense. And still fail to solve the problem.

    Brio closes the gap with patented Advanced Particle Removal Technology (APART™).  Developed over five years at the University of Washington, APART delivers constant clean air flow and effectiveness, with less maintenance, and a lower cost to own than comparable HEPA portable air purifiers. Brio removes fine and ultrafine particles, viruses and germs, smoke, and dust with no filter clogging. HEPA air purifiers can't make the same promise.

    Brio’s effectiveness stays high—and the air stays clean—over the entire period between cartridge replacements. And Brio's long-life, non-clogging particle collection cartridge can last a year or longer before it needs to be changed. Brio can save your company time and money while deep cleaning the air you breathe.
