Certified Ratings
On a voluntary basis, manufacturers certify the Water Removal Capacity and Energy Factor of household dehumidifiers.  AHAM verifies water removal capacity through testing at a third party independent laboratory using the American National Standard, ANSI/AHAM DH-1 test method.    
 
If a unit does not meet the stated performance ratings, the manufacturer must re-rate the product or withdraw the product from the market. 
 
All manufacturers who distribute goods in the U.S. may participate in the Programs, whether or not they are AHAM members.  The programs are financially supported by participant fees and are separate from AHAM dues funded programs.
 
This program increases Consumer, Retailer and Manufacturer confidence by ensuring that products perform in accordance with published claims. 
 
Scope of the Program
This Program covers household dehumidifiers that are rated at between 110 and 120 volts with a maximum rating of 16 amps
 
The program does not cover any other types of dehumidifiers at this time.
 
Certification Seal & Recommended Room Size
The AHAM Certification Seal (shown above), is located directly on each certified Dehumidifier and/or its box/packaging.   
 
Certified Dehumidifier Directory and Dedicated Web Site
AHAM\x{2019}s dedicated Dehumidifier Certification Web Site and the online searchable Directory of Certified Dehumidifiers  can be used to search for models that meet specific needs.  Manufacturers that have their products verified and that bear the AHAM Certification Seal are listed here.
