Replacement Cartridges

Replacement Water Filter Guide

This guide can help you find out what type of cartridge you need to replace or why type you would need to remove a specific contaminant. If you are still unsure of what your system needs, email us or call us at 1-800-955-8561.


Carbon Cartridges

Carbon Block

Replacement Carbon Block Cartridges

Replacement cartridges for reverse osmosis (RO) and undersink systems. Carbon block cartridges remove chlorine, taste and odor reduction, and certain cartridges also remove lead from your drinking water.

Empty Refillable Canisters

Empty Refillable Canisters

Empty refillable canisters work exactly like the GAC cartridges above, maximizing the water's contact with the media. Buying the canister and media separately allows you to refill the cartridges any time they need to be changed.

GAC Media

Granular Activated Carbon Media

Granular activated carbon media for the empty refillable canisters to the left.

Granular Activated Carbon (GAC)

Replacement GAC Cartridges

GAC cartridges allows water to flow from one end through the length of the carbon media inside before flowing out the other end, maximizing the water's contact with the media. These remove chlorine, taste and odor reduction, and can be effective and removing chemical contaminants.

KDF/GAC Replacements

These sealed KDF/GAC Systems typically last for 3 years before replacement is needed. Shown here are an under sink, counter top and ice maker model. These units are also replacement upgrades for discontinued NSA models.



Sediment Cartridges

Pleated

Replacement Pleated Sediment Filters

Pleated filters are designed to have an increased surface area and longer life. These cartridges are washable & reusable, and come in a range of sizes and micron (µ) ratings.

String Wound

Replacement String Wound Cartridges

String wound cartridges are designed for the removal of dirt, rust and sediment from water. These cartridges are rated for temperatures up to 125 °F. Polypropylene construction for excellent chemical resistance. No binders, additives, or lubricants to leach into the water.

Melt Blown

Replacement Melt Blown Filters

Melt blown polypropylene cartridges are designed for the removal of dirt, rust and sediment from water. These filters have graded density layers, meaning the outer layers are more porous, catching larger particles while the inner layers are a finer micron, catching smaller particles.

High Temperature

Replacement High Temperature String Wound Cartridges

High temperature string wound cartridges are designed for the removal of dirt, rust and sediment from water. These cartridges have stainless steel center tubes rated for temperatures up to 180 °F. Polypropylene construction for excellent chemical resistance. No binders, additives, or lubricants to leach into the water.


Reverse Osmosis Membranes

Residential Membranes

Residential RO Membranes

Membranes are designed to remove a range of inorganic contaminants and dissolved impurities including salt ions and other small, unfilterable molecules.

Commercial Membranes

Commerical RO Membranes

Membranes are designed to remove a range of inorganic contaminants and dissolved impurities including salt ions and other small, unfilterable molecules.

Commercial membranes are designed for specific applications: Nano filtration, Tap Water, Brackish Water, and Sea Water.


Inline / Icemaker Filters

Inline Cartridges

Inline / Icemaker Filters

These filters are often used as a Reverse Osmosis (RO) inline post filter. They clip on to the membrane housing and filter the water after the bladder tank, acting as a polishing filter. Other applications include: appliances, water coolers, coffee makers, and other low flow applications.

Ceramic Cartridges

Ceramic Cartridges

Ceramic Cartridges

Ceramic water filters are an inexpensive and effective type of water filter, that rely on the small pore size of ceramic material to filter dirt, debris, and bacteria out of water. Doulton® ceramic filter particles from the water but leaves oxygen and mineral contents unchanged, which gives water it's spring-like freshness and taste (not "pure" but wholesome).

More Information on Cartridges & Micron Sizes

How to Choose a Micron Size

A micron is a unit of measurement for how small of particles a filter will catch. The lower the micron size, the tinier the 'holes' in the filter cartridge are that allows water to pass through, ranging from 0.1 absolute to 150 microns.

Use our Pore Size Efficiency Guide to find out what micron size to use.
