Marine Depot RO/DI Replacement Filter Kit

$40.49 


Item #: RO2113

Ships Free!


Temporarily Out of Stock


Kit Includes:
1 x 1 micron dual density gradient sediment filter
1 x 1/2 micron carbon block prefilter
1 x Color Indicating Mixed Bed DI Cartridge

1 micron dual density gradient sediment filter is highly recommended due to longer life and cost effectiveness. Manufactured from 100% pure polypropylene fibers. The fibers have been carefully spun together to form a true gradient density from outer to inner surfaces.

1/2 micron carbon block prefilter is highly recommended to replace your existing carbon filter and works best with 1 micron dual density gradient filter.

Color Indicating Mixed Bed DI Cartridge is the most effective and easy to use DI cartridge available. It’s unique color changing ability takes the guess work out of determining when it is exhausted.

Please note that these replacement cartridges are interchangeable with Captive Purity`s, Kent Marine`s, and SpectraPure`s RO or RO/DI units. We have researched the best replacement cartridges among these three manufacturers and offer only the best of each below.



**Variations of this product can be found in many online stores. The version we carry is of the highest quality. Although this item is eligible for price matching under our Low Price Guarantee, please be certain the product you want to price match is the same make and model.



Manufacturer information

Marine Depot was started in 1998 by a self-professed reef geek and pre-med student Ken Wong. Ken envisioned a one-stop shop where customers could find everything they needed, from technical product specifications, reef aquarium information, expert advice on the hobby and friendly one-on-one customer support. Having grown from a one-man crew to being one of the world’s largest suppliers of reef and marine aquarium products, this very core philosophy still lives strong in the Marine Depot culture 20 years later.

Good price

Pros: Affordable

Cons: Doesn’t last long, some filters last longer than others, inconsistent.

I have a TDS Meter on mine, I notice I only get about 500 gallons give or take before the filters start going bad. I’d say you probably won’t safely get more than 750 gallons before you should definitely change the filter IME. I’m not an RODI expert but I feel like these should last a little bit longer. But maybe I’m wrong and it’s perfectly normal to last only around 500-750 gallons before needing to change filters.

Great! Fits

Pros: Long lasting, great for RO

Cons: none

This is great it fits any standard RO canister! I get roughly a year of use out of it before I have to replace it. My tank is 100 gallons size

I use it for chamber 1 2 3 and then RO membrane and the DI resin

One of the best

Pros: Amazing product

Simply some of the best filters in the world! Completely removes any unwanted levels in your water, and as long as you flush your system after each use the filters last months!
