Replacement Media Set for Poly Bio-Marine Kold Ster-il

We filter well water through Steril-Kold system for use in our aquarium. These replacement filter cartridges are “original equipment” and function perfectly.

Expensive- but I get 3 years out of them.

Great Product

i bought this system to filter my household water, the third filter is too restrictive, no flow at 60 psi. i called company over ten times with no reply. not happy! gm pa.

Good quality , arrived on time.

Just what I expected.
