RGF Environment Group has participated in the China Hi-Tech Fair for three consecutive years. It is a US-based company specializing in solving air and environmental pollution problems with new, high-tech air purification technologies. The company brings leading RGF-PHI (photohydroionization) technology to this year’s fair, the most efficient air purification technology in the world. It’s worth noting that PHI technology can effectively reduce PM2.5 in the air by agglomerating small particulates into big ones and settling them to floor, preventing inhalable particles that float in air from being inhaled. The process is finished in several seconds and is irreversible; therefore, there is no chance of recontamination.

US-based RGF Environment Group, established in West Palm Beach, Florida, in 1985, is a major manufacturer of environmental protection products. It has more than 500 patented environmental purification products and a large number of engineers, scientists and system integration experts to provide the industry and customers with environmental purification solutions. RGF has been recognized by the United States federal government, state governments, EPA, OSHA, GSA, large multinational companies, and many Fortune 500 companies.
