3M HF20-I (5636428) 3M™ Water Filtration Products Replacement Cartridge

Replace the spent cartridge and keep every pour tasting the way it should.

The 3M HF20-I is the 0.2-micron Sanitary Quick Change replacement cartridge supplied with the BEV120-I filtration system. It delivers a rated 1.67 GPM flow and 14,000-gallon capacity while reducing chlorine taste and odor, Class I particulates, and filterable cysts. Its sealed, twist-on design makes scheduled changeouts fast and wrench-free, so routine filter service doesn’t have to become a plumbing project.

This listing is for the replacement cartridge only. The filter head, manifold, and complete filtration system aren’t included. Order through IceMachinesPlus with the 30-Day Price Match Guarantee, and call 1-877-900-4423 if you need help confirming the cartridge match before checkout.

3M HF20-I specifications

Confirm the cartridge match

Check both identifiers before ordering: HF20-I and catalog number 5636428. This cartridge is supplied with the BEV120-I complete system and may also fit manufacturer-approved High Flow Series heads and manifolds. Confirm the complete head, manifold, or system model instead of relying on cartridge size or appearance.

Similar HF20-S, HF20-SI, HF25-S, and other High Flow Series cartridges have different capacities, flow ratings, treatment functions, and system applications. A similar model number doesn’t establish compatibility.

You may encounter Aqua-Pure branding as the manufacturer updates its 3M-branded drinking-water filtration products. Verify HF20-I and 5636428 even if the packaging reflects the newer branding.

Understand what the cartridge reduces

The 3M HF20-I replacement cartridge uses Integrated Membrane Pre-Activated Carbon Technology, or I.M.P.A.C.T., which combines a membrane with an activated carbon block. When installed in an approved system and operated within its rated conditions, it reduces chlorine taste and odor, nominal Class I particulates, and filterable cysts.

Reducing chlorine taste and odor supports more consistent water, fountain-drink, and ice quality. Particulate filtration also helps limit debris entering connected equipment, pumps, valves, seals, and dispensing components.

The 0.2-micron rating is nominal. It doesn’t mean the cartridge removes every substance that may be present in the water. The HF20-I isn’t documented as a water softener or scale-inhibiting cartridge, and it shouldn’t be used to make microbiologically unsafe water safe.

Review the official 3M HF20-I performance data sheet for the certified claims, operating limits, safety instructions, and complete replacement procedure. If scale or hardness is the main concern, compare compatible treatment in the commercial water filtration systems collection.

Replace the cartridge on time

Replace the 3M HF20-I no later than every 12 months. Install a new cartridge sooner if any of these conditions occurs first:

• The system processes 14,000 gallons
• The downstream flow becomes noticeably slower
• The filtered water develops an unexpected taste or odor
• The cartridge or filtration system becomes damaged
• The manufacturer or local operating requirements call for earlier replacement

The 14,000-gallon figure is a rated capacity under specified test conditions, not a guaranteed service period for every installation. Incoming water quality and actual water use can shorten the practical replacement interval.

Record the installation date when fitting a new cartridge. Operations with measurable water use should also track estimated gallons processed. Our ice machine water filter replacement guide explains how to manage filter changes using time, capacity, pressure, flow, taste, and odor.

Install and flush it correctly

Follow the instructions for the installed filter head or manifold. Some compatible heads shut off automatically when the cartridge is removed, while other configurations require the upstream water valve to be closed and the system to be depressurized first.

Remove the spent cartridge by releasing the locking mechanism when required, rotating the cartridge counterclockwise, and pulling it downward. A saturated cartridge can be heavy, so support it from the bottom. Remove the sanitary cap from the new cartridge, insert it into the approved head, and rotate it clockwise until it locks securely.

After restoring the water supply:

1. Inspect the cartridge and connections for leaks.
2. Flush at least four gallons through the new cartridge, which takes approximately two minutes at the rated flow.
3. Inspect the system again for leaks.
4. Return the connected equipment to service only after flushing is complete.

Flush the cartridge again according to the manufacturer’s instructions whenever the system has remained unused for more than 72 hours. Protect the system from freezing, and remove the cartridge if temperatures may fall below 40°F.

The published operating range extends to 125 PSI, but the manufacturer requires a pressure-reducing valve when incoming pressure exceeds 80 PSI. Installation and use must also comply with applicable plumbing codes.

3M HF20-I FAQs

Is the 3M HF20-I compatible with the BEV120-I system?

Yes. Model HF20-I, catalog number 5636428, is the replacement cartridge supplied with the BEV120-I filtration system, manufacturer number 5616017. It may also fit approved High Flow Series heads and manifolds, so confirm every model identifier before ordering.

How long does an HF20-I cartridge last?

Replace the cartridge no later than every 12 months or after 14,000 gallons, whichever occurs first. Replace it sooner if flow declines or the filtered water develops a noticeable change in taste or odor.

What does the HF20-I water filter reduce?

When used in an approved system under specified conditions, it reduces chlorine taste and odor, nominal particulate Class I, and filterable cysts. The documented system performance is certified under NSF/ANSI 42, NSF/ANSI 53, and CSA B483.1.

How do I know when a 3M cartridge needs to be changed?

Change the cartridge when it reaches 12 months of service, processes its rated capacity, produces noticeably slower flow, or allows an unexpected taste or odor change. Recording the installation date and estimated water use is more dependable than waiting for visible damage.

Does the HF20-I remove scale, bacteria, and every contaminant?

No. The HF20-I isn’t a universal purifier, water softener, or documented scale-inhibiting cartridge. Use it only with an approved drinking-water supply, and match any additional treatment to tested incoming-water conditions.

If your existing cartridge reads HF20-I or 5636428 and your system or approved head matches the manufacturer’s compatibility information, this is the replacement built for the job. If the identifiers don’t match, compare 3M cold-beverage replacement cartridges or call 1-877-900-4423 before ordering.
