Great filter!
"My wife researched and found this filter in place of a reverse osmosis system. I installed it under the sink and our fridge water tastes pure! Happy wife………"


CuZn’s IL-200 Series Water Filters have been saving American’s hundreds of dollars a year in refrigerator water filter expenses for the past two decades and is a sister product to the our CuZn UC-200 Under Sink Water Filter that is the most popular under sink water filter in the United States for 2 decades running.
When buying a CuZn IL-200 Fridge Filter you aren’t just buying a product off the shelf, you are purchasing years worth of guaranteed top quality drinking water service for your home from CuZn.
Fridge manufacturers are trying to force consumers to purchase absurdly overpriced “built-in” fridge water filter cartridges every 6 months, the worst part is this filters are low quality and intentionally designed to fail in a very short period of time. CuZn’s IL-200 Series inline refrigerator filters are compatible with any make or model fridge, featuring industry leading performance, legendary lifetime warranty support and provide better filtration at a significantly lower cost.

The IL-200 Series water filters will reduce a wide variety of organic and inorganic contaminants including but not limited to: chlorine, chloramine, water soluble cation heavy metals (lead, mercury, chromium VI, cadmium, etc.), herbicides, pesticides, sediment, algae, molds, bad taste, odors and other undesirable contaminants that may effect the quality of your water supply.
The IL-200 purifies the water selectively, allowing beneficial mineral content to remain. Hardness Minerals (calcium & magnesium) will pass through the IL-200, the IL-200 Series KDF Filter Media stage may reduce hard scale formation but will not eliminate it entirely. Unlike carbon only filters, bacteria can’t grow inside the bacteriostatic CuZn IL-200 Refrigerator Water Filtration Systems.
The IL-200 requires virtually no maintenance and installs in about 10 minutes, hooking up to the water supply line behind the fridge. When you turn on the fridge dispenser or the ice maker kicks on to make fresh ice, it will all be delicious CuZn purified water. New video installation instructions can be viewed by scrolling further below or searching "CuZn IL-200 Water Filter Install" on Youtube.
The IL-200 Series purify the water selectively, allowing health beneficial water mineral content to remain in the filtered water. An IL-200 Series type water filter system DOES NOT reduce TDS or PPM type meter readings.
To test the IL-200 Series performance, utilize DPD#1 Chlorine Test Strips for the IL-200 "Wide Spectrum" model. Replace the IL-200 Series filter system with a fresh one when chlorine breakthrough is detected in the filtered water. CuZn recommends using sensitive chlorine test strips that list 0.25ppm as the minimum level on the strip for the earliest and most accurate detection of chlorine breakthrough.
Total hardness (total hardness = concentration of calcium & magnesium in the water) will pass through the IL-200 Series type water filter systems and remain in the filtered water dispensed from the systems. Calcium & magnesium are health beneficials minerals to ingest and give the water a nice flavor profile when present at low to moderate levels, the IL-200 Series purification method that allows the Hardness Minerals to remain in the filtered water is one of the reasons why it is a popular choice.
The average level of Hardness Minerals (calcium & magnesium) in city water systems in the USA is only 5 grains per gallon, which is a low to moderate level of Hardness Minerals that is ideal for health and drinking water flavor profile, making a UC-200 series type water filter an ideal choice for folks the vast majority of city water supplies in average Hardness Mineral levels range.
However, there are still some city water supplies that that contain excessively high level of total hardness (calcium and magnesium). The level of total hardness (calcium & magnesium) is used to determine if your water is "soft water" or "hard water", water that contains excessive or extreme concentrations of total hardness is referred to as "hard water".
While it is perfectly healthy to drink water that contains excessively high concentrations of total hardness (calcium and magnesium) that is considered "hard" water, way too high a concentration of Hardness Minerals can cause some minor aesthetic issues. For example, if your water contains excessively high hardness minerals and is considered "hard", you'll experience "hard" water mineral residue build up symptoms (white/tan/light-colored mineral residue on glasses, tea kettles, sink spouts, etc) and perhaps an overly "minerally" flavor profile. If you're experiencing these excessively "hard" water aesthetic mineral residue issues and would like to ensure they are fixed when installing a CuZn Fridge Water Filter, consider purchasing the APEC Reverse Osmosis System instead.
