Charles Choi, the founder of DryClean Filter, is a seasoned expert with extensive experience in the dry cleaning industry. Having operated a dry cleaning business for over 20 years, he served as the president of the Sacramento Laundry Association for four years. During his tenure, he worked diligently to provide education, equipment installation, and key operational knowledge to local dry cleaners, advocating for their interests and maintaining close communication with various Sacramento government departments.

One of his major achievements was persistently working with the Environmental Management Department (EMD) of Sacramento and other regulatory agencies to prove that the DF2000 chemical is non-harmful, which allowed dry cleaners to dispose waste into the sewer system without incurring additional costs. He personally covered the cost of environmental testing to demonstrate the safety of the chemical, leading to thousands of dollars in savings for local dry cleaners. This achievement, unique to Sacramento County, has brought significant innovation to local businesses, as they can now safely dispose waste without paying for wastewater treatment.
