The Highlights

We Filter Molecules

We make membranes that filters molecules under any conditions. Hot, cold, acidic, caustic, vacuum, biologically sensitive...and by now you've got the point. No matter where you want to use them we engineer drop-in membranes to move what you want and stop what you don't.

For Many Applications

We break the trend of needing to invent a new material for every application. Need to filter large molecules for pharma? We prescribe larger pores. Need to filter multivalent ions from a waste water stream? You need small pores. Need to transport protons? We do that too! Our first product is a proton exchange membrane.

Using Inexpensive Materials

We make high performance membranes using materials most people throw away. They're made from environmentally friendly silica gel (think beef jerky package) and yet they behave like polymers - bendable, flexible and compressible. Better performance, longer lifetime and lower cost - it's a brave new world for membranes.

It Takes a Village

Membrion, Inc is a 2016 spin-out from the laboratories of the University of Washington (UW). Commercialization funding from the UW, the Murdock Charitable Trust and Amazon helped to bridge the translation gap to a commercial product.

Most recently, Membrion was awarded a Phase I SBIR by the National Science Foundation for the development of a nanostructured ceramic membrane for redox flow batteries with superior performance and low cost (Award #1648517) and follow-on equipment funding for scale-up was provided by a consortium of California utilities (Rocket Fund).


In total, 11 different funding organizations have evaluated and financially supported Membrion's product development and commercialization plan.
