Survive elevated temperature, moisture, corrosionand fires better than existing technology. Increase safety of operations by performing thesafety function within a wider operational range. Provide for in-situ cleaning and reuse, therebyreducing secondary waste. Minimize costs and risks of contamination posed byhot breaks.Lawrence Livermore National Laboratory LLNL-PRES-5611723 4.

Traditional HEPAFilterCeramic HEPA filterPurchase price for 1 x 1 x 1 size $200 to $300 $2,000 (Cost of components purchased assingle items; can be reduced with bulkpurchasing)Current assembly and testing time (can bereduced significantly with automation): 8 hrsCost of install & replacement (includingpackage, waste shipment, & waste disposal)for process equipment, fume hood, etc.(depends on class of waste)$16,000 per filter Same: $16,000 per filterCost of install & replacement (includingpackage, waste shipment, & waste disposal)in ventilation system (depends on class ofwaste)$2,700 per filter (LLW) Same: $2700 per filter (LLW)Light Use (light dust/moisture/corrosiveenvironment)3 to 5 yearsoperational lifeInfiniteChallenging Use (heavy dust/moisture/corrosive environment)Short operational life Infinite (with cleaning)Savings Up to $14,000 every replacement intervalLawrence Livermore National Laboratory LLNL-PRES-561172 9 10. Ceramic HEPA filters offer unique capabilities andbenefits Safer with large life-cycle cost savings potential Make possible additional process innovations Completed successful proof-of-concept, verified byindependent testing Portfolio of inventions Applicable to a wide range of industriesLawrence Livermore National Laboratory LLNL-PRES-56117210 11.
