About CULLIGAN

Culligan is a water treatment brand with a history dating to 1936, when Emmett Culligan developed a portable water softener. The company's product range has since expanded to include point-of-use and point-of-entry filtration systems, filter cartridges, and inline filters for residential, commercial, and light industrial applications. Culligan products are distributed globally, and 3G Electric supplies a selection of Culligan water filters and cartridges to technical buyers worldwide.

The Culligan line available through 3G Electric includes inline carbon filters for ice machines and refrigerators, under-sink water filtration systems, and replacement cartridges. These products are specified by micron rating, service life, and contaminant reduction claims. For example, the US-3UF system has a 0.5 micron rating and 350-gallon service life and is listed to reduce lead. The US-EZ-4 uses carbon media to reduce particulates with a 0.5 micron rating and 500-gallon service life. The US-EZ-1 reduces chlorine odor with a 5 micron rating and 3,000-gallon service life. The US-DC3 provides 4,750 gallons of service life and reduces Nominal Particulate Class I. The US-600A reduces chlorine taste with a 5 micron rating and 1,000-gallon service life. The US-DC-1 reduces chlorine odor with a 0.5 micron rating and 2,000-gallon service life. The US-EZ-3 reduces cysts with a 0.5 micron rating and 500-gallon service life. The IC-100A inline filter is a carbon media filter for ice machines and refrigerators, reducing chlorine taste, with a flow rate of 0.5 gpm and dimensions of 10 1/2 inches overall height and 2 1/4 inches diameter.

These products are used in drinking water, ice production, and light commercial plumbing applications. The systems are typically installed under sinks or at point-of-use, and the inline filters are installed on water lines feeding ice machines or refrigerators. Build standards include white finishes on some models and carbon block or granular carbon media. The service life ratings range from 350 to 4,750 gallons, and micron ratings range from 0.5 to 5 microns. 3G Electric supports the Culligan line by stocking multiple SKUs, providing specification data, and offering quotation and order fulfillment services for buyers who need to match filters to specific water quality requirements. The product range covers common reduction claims such as chlorine taste and odor, lead, particulates, and cysts, allowing selection based on the contaminant of concern and the required service interval.

Frequently asked questions

Common questions about CULLIGAN from 3G Electric.

What is the difference between the Culligan US-3UF and US-EZ-4 water filtration systems?

The Culligan US-3UF is a point-of-use system with a 0.5 micron rating and a 350-gallon service life, listed to reduce lead. The US-EZ-4 also has a 0.5 micron rating but uses carbon media to reduce particulates and provides a 500-gallon service life. Both are under-sink systems, but they target different contaminants and have different service intervals. Selection depends on the specific water quality issue and desired filter change frequency.

What is the flow rate and dimensions of the Culligan IC-100A inline water filter?

The Culligan IC-100A inline water filter has a flow rate of 0.5 gallons per minute. Its overall height is 10 1/2 inches and its diameter is 2 1/4 inches. It uses carbon media to reduce chlorine taste and is designed for ice machines and refrigerators. The compact size allows installation in tight spaces on water lines feeding ice makers or refrigerated drinking water dispensers.

Which Culligan water filtration system has the longest service life?

Among the Culligan systems listed, the US-DC3 has the longest service life at 4,750 gallons. It uses carbon filter media and reduces Nominal Particulate Class I with a 0.5 micron rating. The US-EZ-1 has a 3,000-gallon service life, and the US-DC-1 has a 2,000-gallon service life. Longer service life means fewer filter changes, which can be advantageous in higher-volume applications.

What contaminants do Culligan under-sink water filter systems reduce?

Culligan under-sink systems in the 3G Electric catalog reduce a range of contaminants. The US-3UF reduces lead. The US-EZ-4 reduces particulates. The US-EZ-1 reduces chlorine odor. The US-DC3 reduces Nominal Particulate Class I. The US-600A reduces chlorine taste. The US-DC-1 reduces chlorine odor. The US-EZ-3 reduces cysts. Reduction claims are specific to each model, so buyers should match the system to the contaminant of concern.

Are Culligan water filter systems suitable for light commercial use?

Yes, several Culligan systems are specified for residential or light commercial plumbing applications. The US-DC-1, for example, is described as suitable for under-sink installation in residential or light commercial plumbing. The US-EZ-3 is also noted for residential or light commercial use. These systems are point-of-use, meaning they treat water at a single outlet or appliance rather than for the entire building.

What micron ratings are available in Culligan water filtration systems from 3G Electric?

Culligan water filtration systems available through 3G Electric have micron ratings of 0.5 or 5 microns. Models with 0.5 micron ratings include the US-3UF, US-EZ-4, US-DC3, US-DC-1, and US-EZ-3. Models with 5 micron ratings include the US-EZ-1 and US-600A. A lower micron rating indicates finer filtration, which can capture smaller particles but may affect flow rate or filter life.
