PortaWell® uses non-proprietary, standard sized, commercially available filters. The 10-inch PortaWell filter housing is common to many residential under sink installations and accepts OBE (open both ends) filters that are nominally sized as 10 inches long by 2 to 2 ¾ inches in diameter.
Our two-Stage filtration system allows for larger filters to be used which mean a higher filtration rate (40 to 60 gallons per hour flow rate) and fewer filter change outs/cleanings. This system also lets you switch out filters to adapt to your surface water contaminants. Use the chart below to find which of the filters we carry will best suit your filtration needs.
