IE grad student Huang invents bio-based air filter

A Purdue IE graduate student has developed a novel bio-based filter alternative that addresses issues of sustainability, health and lower expenses that are desired in the HVAC industry.
Andrew Huang, a Purdue IE masters student, founded Ongenia LLC to bring a new type of soybean-based HVAC filter to market. The novel filter removes fine particles out of the air and could improve indoor air quality and reduce airborne allergens.

The World Health Organization estimates that 90 percent of people breathe polluted air, which causes 7 million premature deaths each year. That's why Ongenia LLC, a Purdue-affiliated startup, is developing a bio-material alternative to standard heating, ventilation and air conditioning (HVAC) units' air filters.

Typical HVAC units control heat and air supply as well as ventilation in indoor spaces to achieve the desired room temperature and humidity. The units also include filters of polyester or fiberglass that remove large particles out of the air. Common air pollutants include dust, smoke and dirt, which can affect both indoor and outdoor air quality.

“Our filter looks and acts like a typical air filter that fits into HVAC units,” said Andrew Huang, a Purdue IE master's student. “However, certain biological properties of our filter allow air to pass through while filtering out specific particulates.”

He founded Ongenia LLC to commercialize this technology, which is licensed through the Purdue Research Foundation's Office of Technology Commercialization.

Huang began developing the filter during his participation in the 2017 Student Soybean Product Innovation Competition, which asked students to find and create innovative soybean-based technology. This air filter alternative, originally based on soybean material, helped Huang and his team, FiltraSoy, win top honors and the People's Choice award at the competition.

“We believe our filters can help reduce in-home allergens and improve indoor air quality,” Huang said. “Biological materials can have many brilliant features, including being a renewable resource and possibly having improved fire resistance.” Later in 2017, Huang also pitched his business model at the Purdue Ag-celerator and received $55,000 in funding to advance his startup. He said he hopes a larger air ventilation company will sublicense this innovative filter from Ongenia.

Currently, the startup is allocating funds to begin technical feasibility studies with the bio-based air filter and build a proof-of-concept prototype.
