The A2B Water Under Counter Filtration system is great for home use or in your recreational vehicle. The ½ gallon per minute flow rate and 600 gallon filtration capacity will provide water for the whole family. Installation is easy with no need for new plumbing. A diverter valve placed on the cold water line for a sink is all that is needed to get flow to the filter. The faucet attaches to the sink or countertop and push on fittings complete the system. Replacement filters are available, however if flow rate is reduced simply scrub the filter and rinse to return the flow rate.
