Nephros  Dual-Stage  Ultrafilter  0.005 Micron  Water  Filter
 Double  the  Filtration,  Double  the  Safety -- filtration up  to  3  months!

 When    failure   is  not   an  option,    Nephros   offers   the   Dual Stage Ultrafilter
 (DSU). Based   on  our   medical - grade  Mid - Dilution  Hemodiafilter, the 
 Nephros DSU  incorporates  the company’s unique  and proprietary  dual stage
 filter technology. The DSU  is  a significant breakthrough in providing   
 affordable   and   reliable  ultrafilter  technology.  The Nephros DSU has a
 0.005 micron filter pore size designed  to  remove  a  broad  spectrum  of  bacteria,
 viral   agents  and  biological toxins. These toxins include  salmonella, hepatitis, 
 HIV, Ebola viruses,  legionella,  fungi   and  e-coli.  The  DSU   removes   these    
 harmful  substances  more  effectively than other  microfilters currently  on 
 the  market.

 The  Nephros  DSU’s unique design  and materials  ensure high flow rates and
 long life.  The   true   redundant  design   provides   the    highest  confidence  in 
 filter longevity  and   performance. The  DSU  is  a  truly  cost  effective, simple 
 and  compact   to  reliably   produce  on-site  ultrapure water where you need it,
 when you need it.
