There are hundreds of brands of under-sink reverse osmosis 
systems. These are typically the best-performing RO units in that they offer more stages of treatment than smaller countertop models. Also, many under-sink ROs employ booster pumps that maintain a higher water pressure, which allows the RO membrane to perform at its peak. When booster pumps are used, some run on electricity and some are powered by water pressure. All under-sink ROs require installation, and almost all come with a separate faucet that is installed on the countertop. Some rapid flow ROs do not require storage tanks.
