Manitowoc ice machine water filters, sizing, and compatibility
Shop Manitowoc ice machine filter systems for compatible commercial ice makers, including Arctic Pure Plus primary assemblies, a 5-micron sediment prefilter, and an AR-2800 replacement filter. The right fit depends on the exact ice machine model, daily production, required flow, installed filter head, incoming water conditions, and current OEM compatibility.
Highlights
-
The Arctic Pure Plus primary line includes the
AR-10000-P,
rated for machines producing up to 600 pounds of ice per day with a 15,000-gallon capacity; the
AR-20000-P,
rated for 601 to 1,000 pounds per day with a 20,000-gallon capacity; and the
AR-40000-P,
rated for 1,001 to 2,500 pounds per day with a 40,000-gallon capacity.
-
Arctic Pure Plus primary systems are designed to reduce chlorine taste and odor, cysts, and fine particulates, while inhibiting scale, in accordance with Manitowoc’s published filtration claims.
-
The
AR-PRE-P prefilter assembly
adds 5-micron sediment filtration ahead of a compatible primary system. It isn’t designed to serve as the primary filter.
-
The
K00374001 AR-2800 replacement filter
is designed for compatible Manitowoc SM-50 and UCP0050A ice machines.
Best for
- Commercial operations using compatible Manitowoc ice machines
- New installations that need a complete OEM filtration assembly with a filter head
- Operators matching a primary system to the exact machine, required flow, daily production, and incoming water conditions
- Sediment-heavy installations that need a prefilter ahead of a compatible primary system
- SM-50 and UCP0050A installations that require the compatible AR-2800 replacement filter
Before you buy
- Confirm the complete ice machine model number and installed filter head before ordering.
- Use the published production range as a sizing guide, not as proof of compatibility with every machine in that range.
- Determine whether you need a complete assembly with a head or only a replacement cartridge.
- Confirm the current OEM replacement cartridge for the installed filter head. Don’t assume an older cartridge number is still current or interchangeable.
- Use the AR-PRE-P only ahead of a compatible primary filter; it does not replace the main filtration system.
- Verify the required flow rate, incoming water pressure, connection size, mounting space and clearance below the head for cartridge removal.
- Have the source water tested when scale or sediment remains a problem. Scale inhibition is not the same as water softening.
- Follow the model-specific installation, flushing, replacement and startup instructions before returning the ice machine to service.

Manitowoc ice machine filter FAQs
Do Manitowoc ice machines have filters?
−
Not always. Many commercial Manitowoc installations use a separate filtration system connected to the incoming water line rather than a filter built into the ice machine. Check the machine, plumbing, and installed filter head before ordering.
What is the best filter for an ice machine?
+
The best filter is the current Manitowoc-approved system for the exact ice machine model and installed filter head. Confirm the required flow, production, incoming water conditions, and replacement cartridge availability; our guide to the
best ice machine water filters for commercial use
explains how to compare those factors.
How often should I change my Manitowoc ice machine filter?
+
Replace an Arctic Pure Plus cartridge every six months or when downstream pressure falls below 20 psi, whichever comes first. Replace it sooner if the rated capacity is reached, and follow the model-specific interval for AR-2800 and other filtration systems.
How do I know when my water filter needs replacing?
+
Replace the filter when water flow or downstream pressure declines, chlorine taste or odor returns, or the cartridge reaches its scheduled interval or rated capacity. Low ice production alone does not prove the filter has failed, as the water supply, cleaning conditions, and machine components can cause similar symptoms.
How do I replace the filter in my ice maker?
+
Follow the procedure for the installed filtration system. Remove the old cartridge, install the exact compatible replacement, flush it as specified, and check for leaks before returning the machine to service. Arctic Pure Plus and AR-2800 systems use different procedures, so follow the manual for the exact filter head or ice machine.
