Frequently Asked Questions
Does this kit include the RO membrane?
No. This is a pre- and post-filter kit only. The membrane is sold separately: BME1812RE75 for 75 GPD systems, BME3013SXL for 400 GPD systems. For a complete kit with the 400 GPD membrane included, see the Vectapure NX Kit with 400 GPD Membrane.
Are Franklin Water filters the same as Waterite filters?
Yes. Franklin Water acquired Waterite and rebranded the Excelpure and Black Max product lines. The replacement filters are identical in fit, performance, and specifications to the original Waterite cartridges.
How often should these filters be replaced?
Pre- and post-filters should typically be replaced every 6 to 12 months depending on water quality and usage.
Can I buy the individual cartridges separately?
Yes. Cleanflow stocks the FWCB1005 carbon block and FWPS1005 sediment filter individually. The kit is a convenience bundle for buyers replacing all stages at once.
Will this kit fit both 75 GPD and 400 GPD systems?
Yes. The pre- and post-filters are the same across both membrane capacities. This kit fits RO453H, RO4153H, RO405400NX, and RO405400TNX.
