Ultrahigh efficacy air purifier for vocs and airborne pathogens
Sonata Scientific offers a compact, modular UVA-driven photoreactor with a novel photocatalyst that continuously destroys VOCs at room temperature and deactivates airborne pathogens. The system achieves 99+% single-pass removal of a broad suite of VOCs down to parts-per-trillion effluent levels without releasing ozone or harmful by-products, and can be combined with HEPA filtration for enhanced performance.
Overview
Sonata Scientific has developed a high-efficiency, UVA-driven photoreactor paired with a novel photocatalyst designed to dramatically improve indoor air quality. The system continuously destroys volatile organic compounds (VOCs) at room temperature across concentrations of 1 ppb to 10 ppm, a range where conventional catalytic and adsorbent technologies fall short. It also filters and deactivates airborne viruses, bacteria, and mold spores, delivering clean air without releasing active oxidizers, ozone, or harmful by-products. The compact, modular design allows integration with complementary technologies such as HEPA filtration to create customer-focused air purification solutions for industrial, healthcare, and commercial environments.
Technical specifications
- Photocatalyst and photoreactor combination: A novel photocatalyst activated by UVA light drives efficient VOC mineralization at the catalyst surface.
- Single-pass destruction efficiency: Demonstrated 99+% single-pass destruction and removal efficiency (DRE) for a broad suite of VOCs, including low-boiling-point molecules.
- Ultra-low effluent levels: VOC oxidation achieves unprecedented parts-per-trillion effluent concentrations with no measurable by-products, including formaldehyde.
- Pathogen deactivation: More than 6-log reduction of MS2 bacteriophage in 5 minutes and 4-log reduction of S. epidermidis in 30 minutes on the catalyst surface.
- Third-party validated: Performance confirmed per GB/T 18801 for removal of formaldehyde, toluene, and D-limonene without measurable by-products.
- Sustainable operation: VOC removal sustained over months of continuous testing.
- Modular and scalable: Configurable for low-flow systems (1–20 L/min) and larger scales (5–20 cfm), enabling pilot and full-scale deployment.
- Integration-ready: Can be combined with HEPA and other air treatment technologies to maximize overall system performance.
Technology readiness level
The technology has been validated through extensive in-house and third-party testing. Sustainable 99+% single-pass destruction and removal efficiency has been demonstrated for a broad range of VOCs, with third-party testing per GB/T 18801 confirming high-efficiency removal of formaldehyde, toluene, and D-limonene without measurable by-products. Pathogen deactivation has been validated against MS2 bacteriophage and S. epidermidis, showing strong log-reduction performance. Future validation will include customer-specified VOC performance testing at relevant concentrations, pathogen deactivation assessments, and scale-up testing from low-flow (1–20 L/min) to larger systems (5–20 cfm) to optimize designs and define pilot process conditions. This next phase is expected to take approximately six months, with support sought for third-party testing, key personnel, and system studies.
About Sonata Scientific
Sonata Scientific is a nanotechnology research company specializing in industrial indoor air quality (IAQ) solutions. Their core technology platform utilizes a patented photocatalyst to generate Reactive Oxygen Species (ROS) when activated by light, which destroys volatile organic compounds (VOCs) and airborne pathogens by converting them into harmless byproducts like water and carbon dioxide. Unlike traditional scrubbing systems that merely store pollutants, Sonata’s approach is designed for high-performance removal, achieving reductions to parts-per-trillion levels. Their flagship product line, Helios, provides a mobile, ductless, and plug-and-play solution specifically engineered to capture and eliminate fugitive ethylene oxide (EtO) emissions—a common byproduct of medical device sterilization—at the source without requiring infrastructure modifications or disruptive facility changes.
These innovations are critical for manufacturers, healthcare facilities, and logistics providers who need to ensure workforce and community safety while navigating increasingly stringent air quality regulations. By providing effective, sustainable, and portable air purification, Sonata helps organizations maintain clean environments throughout the supply chain, from sterilization areas and warehouses to distribution centers and transport. The company’s technology has been validated in industrial sterilization environments, demonstrating high destruction removal efficiency (DRE) for EtO. Sonata Scientific’s research and development efforts are supported by various U.S. federal and state agencies, including the National Science Foundation (NSF), the Environmental Protection Agency (EPA), the Department of Agriculture (USDA), and the Food and Drug Administration (FDA), which have funded multiple projects to address air quality, pathogen inactivation, and ethylene management.
