SUNON Flow2one PLUS+: Transforming Indoor Air Quality with Innovation
In 2020, the global outbreak of COVID-19 heightened public awareness of home environments, clothing hygiene, and air quality. Among these concerns, indoor air quality was often overlooked in the past. According to research by the U.S. Environmental Protection Agency (EPA), indoor air pollution levels can be 2 to 5 times higher than outdoor air, and in severe cases, up to 100 times worse. With people spending over 80% of their time indoors daily, ensuring clean indoor air has become a crucial issue. However, relying solely on air purifiers is not enough, as they only filter recirculating air without introducing fresh airflow. The refreshing sensation of an open window is difficult to replicate.
To address this problem, SUNON Flow2one PLUS+, developed by SUNON, a company deeply rooted in Taiwan, offers a breakthrough solution. By bringing in outdoor air, it allows people to experience natural airflow even in sealed indoor spaces. Additionally, it effectively reduces CO₂ concentration and formaldehyde levels, issues that conventional air purifiers fail to resolve. Through its unique perspective, SUNON continuously innovates to redefine indoor air experiences. But what fuels SUNON’s drive for relentless innovation?
A Single Line in a Journal Sparked a Legacy of Innovation
Founded over 40 years ago, SUNON Precision Industry Co., Ltd. (SUNON) traces its innovative spirit back to an unexpected source. In 1980, Chairman Hong Yin-Shu came across a scientific journal article featuring American physicist Richard Feynman. The article stated:
"In the future, quantum mechanics will allow an entire Encyclopedia of the U.S. Congress to be stored on a chip as small as a speck of dust..."
At that time, computers were as large as small conference rooms, making this concept revolutionary. This vision shocked and inspired Chairman Hong, leading him to envision a future where every household would own a compact personal computer.
Starting as a small family-run fan assembly business, Hong leveraged his expertise in motor components and his foresight into computing trends to pioneer the micro-motor industry. Today, 1 in every 3 laptops worldwide is equipped with a SUNON cooling fan.
Initially, SUNON set its sights on the U.S. market, the birthplace of computers, aiming to penetrate it with low-cost strategies. However, results were disappointing. Meanwhile, in Europe, SUNON faced distrust from customers and manufacturers. In its first three years, orders were scarce, and products were rejected and returned.
Yet, despite these setbacks, SUNON remained committed to perseverance and continuous innovation. Over time, it earned the trust of European clients, leading Chairman Hong to realize that long-term sustainability was the key to international success.
Overcoming Challenges and Strengthening Intellectual Property
In its early years, SUNON faced legal warnings from international competitors over patent infringement. This shook the company but also accelerated its awareness of the importance of intellectual property (IP) protection. This realization became the foundation of SUNON’s innovation-driven approach.
In 1986, against the objections of colleagues and family, Chairman Hong boldly applied for patents in 23 countries, laying a crucial foundation for SUNON’s long-term success. As he once said:
"Money can always be earned again, but if you don’t file for a patent, it’s gone forever."
To date, SUNON holds over 2,700 patents worldwide, and this number continues to grow. This achievement highlights Chairman Hong’s extraordinary strategic foresight and solidifies SUNON’s place as a leader in air ventilation and micro-motor innovation.

Bringing Fresh Air Indoors: SUNON Flow2one PLUS+ Wins Taiwan Excellence Award
The award-winning SUNON Flow2one PLUS+ is the result of years of dedicated research and innovation by SUNON, a brand of SUNON Precision Industry Co., Ltd. While fresh air systems may be unfamiliar to many, they are essential for providing truly fresh indoor air. SUNON has leveraged its expertise in precision motors, micro fans, and thermal modules to develop an energy-efficient, quiet, and comfortable next-generation ventilation system.
For SUNON, quality is life. The company’s philosophy is to focus less on words and more on research and development. Creating unique products and technologies has always been its ultimate goal. This commitment has led to the development of the Flow2one PLUS+, a multi-functional ventilation system with five-in-one capabilities. A single unit integrates the functions of an air purifier, dual-flow fresh air system, total heat exchanger, air quality monitor, and aroma diffuser.
With dual-turbine design and dual-layer filtration, the system effectively removes airborne particles while bringing in oxygen-rich fresh air, simultaneously expelling indoor pollutants for 360-degree air purification. It features a DC energy-saving motor for ultra-quiet operation and incorporates a total heat exchanger to balance indoor and outdoor temperatures, reducing the burden on air conditioning systems while maintaining optimal indoor temperature and humidity. Even with closed windows, users can enjoy continuous ventilation and comfort.
Additionally, the Flow2one PLUS+ is designed with customizable fragrance and hanging accessories, allowing users to personalize their living space with their preferred scents, plants, or decorative elements. SUNON aims to transform household appliances into products with warmth, seamlessly integrating them into any home interior.
Unaffected by the Pandemic, Spreading Positive Energy Across Society
The COVID-19 pandemic has had a global, far-reaching impact, but how did SUNON Precision Industry Co., Ltd. respond during this challenging time? The company quickly adapted to the changing circumstances. The external business team had to track how the pandemic affected customers' demands for product shipments, adjusting orders and deliveries as necessary. The procurement team ensured the supply chain could provide the necessary materials and components on time, overcoming the tightest resource constraints to meet customer expectations and ensure uninterrupted service.
Internally, SUNON prioritized protecting employees from the threat of the virus. The company used both rigid and flexible measures to raise awareness of preventive actions and fully complied with government directives. Thanks to the global teamwork and cooperation, SUNON achieved the remarkable result of zero confirmed cases among nearly 10,000 employees at its China manufacturing facility and Taiwan headquarters, ensuring normal operations throughout this crisis.
In addition to its response to the pandemic, SUNON continues to focus on developing green products and remains dedicated to its environmental responsibilities and corporate social initiatives. As early as 1989, Chairman Hong Yin-shu established the Shengyuan Qi Ren Center, driven by his personal family experiences, with the goal of helping children with physical challenges shine in society. Over the past 30 years, the center has supported the growth and development of more than 400 children, helping them integrate into society and achieve remarkable success.
In 2007, SUNON also established the SUNON Charity Foundation, actively engaging in social welfare programs, supporting vulnerable groups, promoting moral education, and providing emergency assistance to struggling families, including aid for living expenses and educational support. The foundation also encourages company employees to go beyond the office, visiting towns and villages across Taiwan to deliver supplies and the inspirational book "Liao Fan's Four Lessons" to show care and spread positive energy, aiming to give back to society.

Rooted in Taiwan, Spreading Its Leaves Worldwide
SUNON Precision Industry Co., Ltd. has been deeply rooted in Kaohsiung for many years. Despite the lack of abundant transportation resources compared to Taipei, Chairman Hong Yin-shu firmly believes that a good company, product, and technology are the fundamental paths to success. This belief is also why SUNON frequently participates in the Taiwan Excellence Awards. The Chairman believes that the term "excellence" signifies innovation, and he hopes that participating companies focus on research and development, improving and accumulating technology, as well as market power to create greater value. For small and medium-sized enterprises with limited resources, the Taiwan Excellence Award is an excellent platform to showcase products to the world. He strongly encourages award-winning companies to learn about various promotional activities, select suitable marketing combinations, and actively seek exposure opportunities. Through the recognition and prestige of the Taiwan Excellence Award, he hopes more people will notice SUNON's efforts.
In the future, SUNON will continue to refine its high-efficiency heat dissipation technology, aiming to provide energy-saving ventilation products that will contribute to a better society and environment.
