A review of under-sink reverse osmosis (RO) water filtration explains that RO removes far more contaminants than basic carbon filters, including lead, nitrate, arsenic and PFAS 'forever chemicals.' It notes two system types: tanked RO units that filter passively without electricity, and pricier tankless units that filter on demand but require power. Industrial water treatment expert John Voll says US tap water is generally safe, but contamination problems are local rather than nationwide.

Scientists are developing techniques to remove PFAS, or 'forever chemicals,' from water supplies, including reverse osmosis filters, foam fractionation, and metal nanolayers that capture the compounds. University of Georgia professor Jack Huang is testing electrochemical degradation, which uses electrodes to break PFAS bonds and destroyed over 90% of PFAS mass in trials; the method has been licensed by engineering firm AECOM. Meanwhile, states like Minnesota, Maine and New Mexico have banned PFAS in products such as cookware and dental floss.

Coffee industry sourcing expert Jose Lepe of Sightglass Coffee explains that high-end coffee shops often use reverse osmosis systems to strip tap water down to pure H2O, then remineralize it to a specific balance for optimal flavor. The report notes this same process can be replicated at home without expensive equipment, and contrasts tap water mineral profiles in cities like New York, Los Angeles and London to show how local water quality affects both coffee taste and machine longevity.

Waterdrop's M6CG is a countertop reverse osmosis system that filters tap water through eight stages, removing contaminants like fluoride, lead, arsenic, chlorine and PFAS while also using UV light to kill germs. Unlike under-sink systems, it requires no plumbing installation and adds back alkaline minerals such as calcium, magnesium and zinc, while also offering hot and cold dispensing.
