3M Aqua-Pure AP5500RM under sink reverse osmosis replacement module for use in the AP-RO5500 system installs under the kitchen sink and delivers cleaner, clearer, better tasting drinking water through a dedicated drinking water faucet. This system provide water filtration on demand for drinking water, coffee, tea, baby formula, and cooking purposes. Our universal system design allows for use on both chlorinated (municipal) and non-chlorinated (well water) systems. To maximize system performance and efficiency, regularly scheduled maintenance is required, which includes replacement of the filter cartridges at the required interval, at the rated capacity, or sooner if a reduction in water flow occurs.
