The Simple One® will make you compliant with the new Federal EPA rule in your state. By eliminating the build-up of hazardous mercury in the suction lines from the chairs to the central suction system, you’ll avoid costly cleaning of the same lines. Our amalgam separation process is the easiest in the industry. We can confidently say, this will save you money on filter and labor costs throughout the maintenance and recycling process. We recommend changing out the filter annually.
