Dr. Langer received his B.S. in Chemistry (2002) from the University of St. Thomas, and Ph.D. in Materials Science and Engineering (2012) from the University of Illinois at Urbana-Champaign (UIUC). Jim cofounded Serionix in 2011 to commercialize high performance filtration materials for removal of toxic chemicals from air and water. Within two years of starting the company, he successfully directed early business and technical development of Serionix resulting in public and private funding in excess of $3M.

our commitment

our vision We understand that for most of us, filters are confusing, boring, mysterious products we interact with only when we are forced to do so. We have made it our mission to change that with our engaging Colorfil™ filters that let you know when they’re working and when they aren’t.

We are committed to transparency, to be completely honest about what our filters do and how they do it, and to put our every effort into creating products and experiences you trust and enjoy that provide you with peace of mind.

our story Serionix originated from University of Illinois at Urbana-Champaign in 2011 through coordinated efforts by Professor James Economy, James Langer and Weihua Zheng. Through years of extensive research and development, our team has developed an award-winning filtration technology that has received support from the Army, the National Science Foundation, and NASA (it may even be used in space suits!) in excess of $3M.

concerned parent

“I found the smell embarrassing if we had company in that room. The filter was amazing! I was amazed at what a difference the air purifier and Serionix filter made!”
pet owner

“My daughter recently got two rats. A few days after she got them her room had a mild musty smell. We cleaned the cage multiple times but could not get the musty smell to go. We assumed it was just ‘rat’ smell and would be there for good. Then we installed the Serionix filter and within one hour the smell was gone and it stays gone (even when she forgets to clean the cage). I am a complete convert — these filters are AWESOME!”

“What the filter has done so far, I can’t put a price on that. It’s priceless how it has given my son relief from his allergies.”
