If You Can Measure It, You Can Improve It

CRI’s Seal of Approval (SOA) program is the carpet industry’s only scientific program to test the effectiveness of carpet cleaning products and equipment. To achieve SOA certification, products go through rigorous laboratory testing to meet the high standards of the SOA program. The program helps consumers make informed decisions and helps manufacturers improve their products. The results are cleaner, healthier, and longer-lasting carpet.

How We Test
