Manitowoc ice machine filter guide
A correctly sized Manitowoc ice machine filter helps reduce sediment, chlorine taste and odor, cysts, and scale formation before incoming water reaches the machine. This collection includes Arctic Pure Plus primary systems, a 5-micron prefilter, and an AR-2800 replacement cartridge. Match the equipment to the complete ice-machine model, daily production, required flow, installed filter head, and incoming water conditions.
Arctic Pure Plus options
-
The
AR-10000-P
is rated for machines producing up to 600 pounds of ice per day. It provides 0.75 gallon-per-minute maximum service flow and a 15,000-gallon chlorine-reduction capacity.
-
The
AR-20000-P
is rated for machines producing 601 to 1,000 pounds per day. It provides 1.25 gallons per minute of maximum service flow and a 20,000-gallon chlorine-reduction capacity.
-
The
AR-40000-P
is rated for machines producing 1,001 to 2,500 pounds per day. It provides 2 gallons per minute of maximum service flow and a 40,000-gallon chlorine-reduction capacity.
- Arctic Pure Plus primary systems use 0.5-micron filtration with carbon media and scale inhibitor to reduce chlorine taste and odor, fine particles, and cysts while helping inhibit scale formation.
-
The
AR-PRE-P prefilter assembly
captures sediment, sand, dirt, and rust at 5 microns before the water reaches a compatible primary filter. It doesn’t replace the main filtration system.
-
The
K00374001 AR-2800 replacement filter
is intended for compatible Manitowoc SM-50 and UCP0050A ice machines. It isn’t interchangeable with Arctic Pure Plus cartridges.
System applications
- New Manitowoc installations requiring a complete Arctic Pure Plus assembly with a filter head
- Commercial ice makers requiring a primary system matched to published daily production and service flow
- Water supplies with sediment that can benefit from an AR-PRE-P ahead of the primary filter
- Existing Arctic Pure Plus systems requiring the exact replacement cartridge specified for the installed head
- Compatible SM-50 and UCP0050A machines requiring an AR-2800 replacement filter
Compatibility checks
- Confirm the complete ice-machine model and installed filter-head number before ordering. Production range alone doesn’t prove compatibility.
- Determine if the installation needs a complete assembly with a head, a primary replacement cartridge, a prefilter, or the model-specific AR-2800 cartridge.
- Confirm the current OEM replacement number for the installed head. Older and newer Arctic Pure cartridge generations aren’t automatically interchangeable.
- Use the AR-PRE-P only before a compatible primary filter. The prefilter removes coarse particulate matter but doesn’t provide the primary system’s chlorine, taste, odor, cyst, or scale treatment.
- Arctic Pure Plus systems require cold water between 40°F and 90°F and operating pressure between 35 and 125 psi.
- Install the assembly vertically with the cartridge hanging downward, and preserve at least 2.5 inches beneath the cartridge for replacement.
- Test the incoming water when hardness, sediment, or recurring scale remains a concern. Scale inhibition can reduce deposit formation, but it doesn’t soften water by removing dissolved minerals.
- Replace the cartridge every six months, when the pressure gauge reads below 35 psi, or when its rated capacity is reached, whichever comes first.
- Flush a new Arctic Pure Plus cartridge for 10 minutes, check for leaks, and follow the current installation 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 assembly connected to the incoming potable-water line rather than a filter built into the ice machine. Check the machine, plumbing, and installed filter head before ordering.
Which Manitowoc ice machine filter fits my equipment?
+
The correct filter matches the complete machine model, published daily production, required service flow, incoming water, and installed head. The AR-10000-P, AR-20000-P, and AR-40000-P cover different production ranges, while the AR-2800 serves specific SM-50 and UCP0050A installations. Our
commercial ice-machine water filter guide
explains the main sizing factors.
How often should an Arctic Pure Plus cartridge be changed?
+
Replace the cartridge every six months, when the system’s pressure gauge reads below 35 psi, or when the rated capacity is reached, whichever comes first. Water conditions and heavy use can require earlier replacement.
How do I know when the water filter needs replacing?
+
Replace the cartridge when the pressure gauge falls below its specified limit, water flow becomes restricted, chlorine taste or odor returns, or the cartridge reaches six months or its rated capacity. Low ice production alone doesn’t prove the filter is responsible because water-supply, cleaning, drainage, and refrigeration problems can cause similar symptoms.
How do I replace an Arctic Pure Plus cartridge?
+
Turn the old cartridge one-quarter turn to the left and pull it downward. Insert the exact compatible replacement, push it into the head, and turn it one-quarter turn to the right until it stops. Flush the new cartridge for 10 minutes, expel trapped air and carbon fines, and check every connection for leaks.
