I would like to share some additional information about GreenFumeHood  
technology that I received from the Erlab Group.  In earlier messages,  there were 
some questions about testing of these new types of devices.
James A.  Kaufman, Ph.D.
The Laboratory Safety Institute  (LSI)

In 1989, a test was ordered by the N.I.H. to be performed on  traditional 
filtering fume hoods. The results and conclusions of this test  were then 
"as is" in 2004. This twenty year old test cannot seriously be taken as a  
basis to  
evaluate in 2008 the new GFH with Neutrodine  technology. 
Applying this method to every other product would be like denying any  
possibility of  
progress. Over any 20-year period, millions of products have evolved  through 
experimentation and research: cars, airplanes, computers, telephones,  etc…  
And the Neutrodine filtration system of GFH belongs in this same  category. 
In 2008, the  GFH fume hood was tested by an independent laboratory  
and recognized in the U.S.A.  The tests were conducted by Intertek  
(_www.intertek-labtest.com_ ( )  in 
accordance with the following standards: 
•  ASHRAE 110 requirements 
•  ANSI-Z9.5 compliance 
•  UL, CE and electromagnetic compliance 
•  Requirements of the new French NFX 15-211 Standard* (due to the 
non-existence of  a  
U.S. performance  standard) 
GFH met or exceeded all testing  requirements. 
*The French NFX 15-211 Standard was revised and updated in 2008 by an  
official standards committee comprising 19 specialists, comparable to the  
American National Standards Institute (ANSI). The committee included  
PhDs, HVAC engineers, filtration specialists, occupational health and  safety 
specialists, and the standard was examined by 65 independent entities  
including: Pasteur Institute, Sanofi Aventis, Waldner, British Standards  
(B.S.I.) and more. The NFX 15-211 Standard is not a manufacturer’s  standard. 
It is  
the only standard in today’s market capable of legitimately evaluating  the 
of a filtering fume hood according to strict results criteria. It  requires, 
for example,  
that no more than 1% of the  TLVs of each of the handled chemicals be present 
the air released by the filtration system.  In other words a constant 
filtration  efficiency  
of at least 0.01 of the TLV of the chemicals  handled. 
For 40 years,  ERLAB has built its reputation based on honesty and the high 
of technology  of its products. The company has heavily invested in its R&D  
laboratory and  in the new GFH line, an innovation of public interest in the  
arena of  energy savings. ERLAB is  inviting anyone interested to come and  
visit its  Rowley, Massachusetts facility and receive a  demonstration of the 
GreenFumeHood with Neutrodine technology. It is an open invitation to come  
and form an  opinion for yourself—as many others have before you—on the  
relevance,  reality and performance of this new technology.  Contact: (800)
