The Environmental Water Systems Essential Max Flow is an under-sink drinking water filter that delivers 2.5 GPM through the existing kitchen faucet. Each filter treats up to 10,000 gallons or runs one year, and it needs no drilling, extra faucet or storage tank.
An extruded carbon block cuts lead, cysts, PFAS, chlorine and chloramine, along with VOCs, THMs, pesticides and pharmaceutical residues. The system has been independently tested to NSF 42/53 and complies with FDA, ANSI and California AB1953 standards. It works on both city and well water and wastes no water.
Installation typically takes under 10 minutes, and the filter is changed with a twist and click once a year. Materials are food grade with no BPA, phthalates or glues. It suits kitchens, wet bars, bathrooms, apartments, dorms and rentals. It is offered in several pack quantities and weighs 4 lb.
