Erlab Filters vs. New EPA Standards for Methylene Chloride
Methylene Chloride Retention in Erlab Filters
Comparative Breakthrough Performance of Neutrodine®, Unisorb®, and AS Filters
In response to the U.S. EPA’s 2022 revision of exposure limits for methylene chloride, reducing the occupational threshold to 2 ppm: Erlab conducted an extensive study to validate the retention capacity of its filters. Using a TD/GC/MS analytical method, this test report details breakthrough and saturation performance for Neutrodine®, Unisorb®, and AS filters in a Class 1 ductless filtration hood.
Results confirm that Erlab’s Unisorb® filters offer the highest retention duration and mass before reaching 0.02 ppm downstream concentration, supporting safe chemical handling in labs using methylene chloride.
ERLAB R&D LABORATORY
The engineers and chemists in our state-of-the-art R&D laboratory understand molecular filtration. We are committed to designing products that are safe and of the highest quality, strive to improve our products, and continuously develop new products that provide greater protection in the laboratory.
STRICT SAFETY STANDARDS
We hold ourselves to the highest standard and adhere to the strict AFNOR NF X 15-211: 2009 filtration safety standard as endorsed by ANSI Z9.5-2012.
A PUBLISHED CHEMICAL LISTING
It all begins here. Without this listing, we are not compliant with AFNOR NFX 15-211. Our in-house laboratory tests, as well as independent testing, to verify the retention capacity of over 700 chemicals for our filters.
INDEPENDENT TESTING
Erlab filters have been independently tested multiple times at various concentrations guaranteeing that our safety solutions all adhere to the strict performance criteria of theAFNOR NF X 15-211:2009 standard assuring that the emission concentration at the filter exhaust will always be lower than 1% of the TLV.
APPLICATION QUESTIONNAIRE (VALIQUEST)
Our laboratory specialists will recommend the appropriate filtration fume hood, type of filter, and personalized advice.
CERTIFICATE OF VALIDATION FOR THE CHEMICALS USED IN THE HOOD
A certified PhD chemist issues a Certificate of Validation with a list of the chemicals approved for use in the hood.
Our Safety Program
We back up our products 100%. This program includes your specialized chemical evaluation, validation of your hood upon installation, and a filtration safety specialist at your service to ensure that your hood is operating to its full potential.
