The SWF-45-1010 Water Filter has been discontinued. Purchase the compatible alternate, Tier1 P5-10BB-WF
Water Filter below. The P5-10BB-WF filter is a 5 micron filter and will filter more finely than the 10 micron SWF-45-1010 filter. It will restrict water flow more than the SWF-45-1010. The P5-10BB-WF is a poly spun filter rather than a string wound filter. Poly spun is a different style of construction but offers performance very similar to the string wound filters. Alternatively, purchase a case of 8 of the compatible Pentek WPX10BB97P
, 10 Micron, String Wound Water Filters below.
