3M Water Filtration Buying Guide

3M commercial water filters - first introduced under the Cuno name, have set the benchmark for food-service water treatment for decades. The brand’s ownership has evolved (Cuno became 3M Water Filtration, the division spun off as Solventum in 2024, and the line is being folded into Thermo Fisher’s Aqua-Pure™ portfolio), yet every cartridge and model number remains fully compatible and NSF certified. Foodservice operators worldwide continue to rely on these systems to improve taste, clarity, and safety while shielding equipment from scale and sediment. Whether you are outfitting a brand-new kitchen or upgrading an existing setup, 3M’s extensive lineup makes it easy to choose the capacity and performance that fit your specific needs, so every pour meets the highest standard.

1. The 3M Water Filter Difference

• Eliminates unpleasant tastes & odors by trapping chlorine, chloramine, and organics.
• Industry-leading flow rates keep up with peak service without pressure drops.
• Crystal-clear water & ice for beverages guests can see and taste the difference in.
• Incredibly efficient media extends cartridge life, cutting replacement costs.
• Compatible across equipment - ice, coffee, espresso, steam, and fountain.
• NSF-certified safety with up to 99.99 % bacterial and cyst reduction.

Why pros choose 3M

Every 3M system removes taste-spoiling chlorine, sediment, lead, and other contaminants, but what sets the brand apart is how fast and consistently it does the job. High-capacity cartridges deliver the flow a busy kitchen needs, even during the rush, while I.M.P.A.C.T. dual-zone media combines premium activated carbon with a patented membrane to extend life and maintain water pressure.

Purpose-built for each station

Beyond standard hot- and cold-water filters, 3M engineers models for ice makers, soda fountains, espresso machines, and combi ovens. The FDA classifies ice as a food, so an ICE-series filter ensures every cube is as clean as the drink it chills, while protecting evaporator plates from scale. Pair a BREW-series cartridge with your espresso or drip brewer and customers will taste coffee, not minerals.

Lower cost of ownership

Longer cartridge life means fewer change-outs, less downtime, and lower spend over time. Quick-change SQC heads twist off in seconds, no tools, no mess, so staff can swap filters between orders. When you factor in equipment protection and reduced service calls, a 3M filter often pays for itself within a single replacement cycle.

2. Which 3M Water Filter System To Buy

In order to determine which 3M commercial water filter system your foodservice operation needs, you first need to answer some questions:

• Am I sizing this for a specific application (ice, coffee, espresso, steam)?
• How many gallons per day (or pounds of ice per day) does my operation use?

As mentioned, the 3M brand offers a wide variety of models meant to suit businesses of all stripes. That being the case, it may not be immediately apparent which water filter is best for you. Let’s start with the obvious; if you need a specialized water filter (as in, one for an espresso or ice machine), you’ll need a model designed to work specifically with that machinery. From there, your decision will likely be determined by the volume of your business. A smaller operation, for example, can make excellent use of the 3M ICE120-S, an economical model whose small size belies its incredible capabilities. Businesses on a larger scale, meanwhile, may be better served by the 3M ICE265-S. Its astonishing flow rate of 6.68 GPM and its ability to filter 70,000 gallons of water before cartridge replacement makes it a dedicated and reliable addition to your operation.

The 3M model you choose for more general filtering needs will also likely be dictated by the volume of your business. For other brands, buying an economical model means compromising quality for cost; not so with 3M filtration products. The BEV160, for example, can produce 35,000 gallons of clean and refreshing water on one cartridge, making it an entry-level water filter whose features outshine many of the competition’s much more expensive models. As impressive as those numbers are, however, they pale in comparison to the models 3M offers for hotels and other large-scale operations; one need only look at the unbelievable features of the DP390 for proof of that. Its cartridges can process a whopping 162,000 gallons at an unbeatable flow rate of 15 GPM, which makes it the standard-bearer for any owner looking for the ultimate in quality, affordable water filtration.

4. Maintaining Your 3M Cuno Water Filter System

The best filtering technology in the world, however, won’t be of any use if it’s not well-maintained. Though the model you purchase will come with cleaning and maintenance instructions specific to that filter, there are a few guidelines you should keep in mind no matter which variety you choose.

• Replace cartridges every 6-12 months or when flow drops by 15%, whichever comes first.
• Store spare cartridges in a cool, dry, ventilated space to preserve media quality.
• Log each change-out date and set digital reminders so replacements never slip.
• Check incoming water pressure during weekly walk-throughs; 60-70 psi is ideal, below 35 psi indicates a clog.
• Inspect the system for leaks, discoloration, scale, or corrosion during each check.

Reminder: GoFoodservice stocks genuine 3M replacement cartridges and may offer volume discounts, ask our customer service team for details.
