## Ultra-Fine Particulate Matter Filtration

**                               **

*Portable Ultra-Filter Unit for Spacecraft Cabin Air Purification*

- The Y2 Ultra-Filter technology employs a uniquely configured electric field surrounding porous filter media to cause airborne particulate matter in the process stream to move in a churning motion perpendicular to the flow direction without ionization. The motion significantly enhances the London/Van der Waals force interaction between the particulate matter and the filter media, resulting in a super-efficient filter. The filter is capable of capturing smoke, bacteria, viruses, odorants, dust, and many other sub-micron-sized particulate matter including ultra-fine particulate matter.

**	****	****             ****ACCOMPLISHMENTS**
- Prototype demonstration is being scheduled for automotive, aircraft, HVAC, semiconductor manufacturing, commercial cooking, and military applications.
- Third-party verification testing for DARPA has achieved capture efficiencies of 99.999% at 100 cfm for sub-micron particulate matter. Testing at flows up to 3,000 cfm are in progress. An optimized design is being assembled at flows up to 2,000 cfm that has the goal of 99.9999% sub-micron particulate matter arrestance.
- Advantages of Y2 technology: higher efficiency, captures a wider range of particles, lower pressure drop, lower energy consumption, particle holding capability, gating filter, odor suppression, no ionization, low maintenance/operating costs, and biodegradable filter material.
- Over $2 million of private capital has been invested by the firm over the past 10 years.
- Several multi-billion dollar companies have had detailed discussions w/ Y2 Ultra-Filter.
- Has demonstrated success in particulate removal from air.
**            ****COMMERCIALIZATION**
- Technology presently holds 4 U.S. patents and 11 foreign patents.
- Target market sectors include automotive, aircraft, HVAC, semiconductor manufacturing, and military applications.
- Product introduction into several target markets within the next 6 months.
- Received license fees and royalty payments. These revenues are integrated into future business ventures.
- Business model is in the form of business units by market sector. Y2 Ultra-Filter establishing strategic alliances with major filter manufacturers.
