SpectraPure® Standard 0.5 Micron Prefilter Replacement Kit -FK-SFCF-0.5

Great product

Use their 6 stage water system for my salt water aquarium. Works great, was easy to set up and the water filters seem to last a long time for the way I use it.

I had an old housing and upgraded to the CPSDI Membrane. It’s been functioning well with 0 TDS. Great support with any questions.

Hands down the best place for rodi supplies

Exactly what we needed. 1 to 1 replacement of our filters.
