3M Water Factory SQC4 RO Filter Kit-Membrane Sold Separately
Filter Replacement Kit for 3M Water Factory SQC4 Reverse Osmosis System (RO Membrane Sold Separately)
INCLUDES:
We offer two replacement filter kits so you can get exactly what you need — and avoid paying for filters you don’t.
Year 1 Kit (Includes RO Membrane):
Ideal for your first full replacement, this kit includes all filters plus the RO membrane, which typically lasts up to 24 months.
Year 2 Kit found on this page (Without RO Membrane):
After the first year, you only need to replace the pre- and post-filters, since the RO membrane is still good for another year. This kit helps you save money while keeping your system performing like new.
*Filters may need to be replaced more often than indicated, depending on incoming water contaminant levels and volume of water being treated.

"I have had an SQC 4 water filter system for many years. In the past, it has often been a long process in finding replacement filters. In most cases, I needed to take alternative filters instead of the 3M filters that I prefer. Since the time I signed up ESP Water, I have nothing but good experiences. The service and the advice I have had from this company has been excellent. I would recommend this company to anyone interested."
"Even though part of my order wasn't sent , I appreciate the speed in which you made it right."

Q:
How do I replace my 3M RO filters?
A:
Start by selecting your reverse osmosis system above. You'll be taken to a page that provides manuals or instructions for your specific model. For your convenience, we also offer general reverse osmosis filter replacement instructions.
Q:
How do I order replacement filters for my 3M drinking water filtration system?
A:
Begin by selecting the image of your 3M reverse osmsois system displayed above. This will guide you to add the required filters to your shopping cart. For convenience, consider opting for a "filter kit" that bundles all essential filters together, although this option might not be available for all 3M models. It's worth noting that the RO membrane typically requires replacement every two years. In contrast, sediment and carbon filters need changing every 6-12 months, contingent on water usage and water quality.
Q:
Which 3M membrane or filters do I need for my RO filter system?
A:
Select your 3M reverse osmosis system from the list above. You will be taken to a new page that shows the available membrane and filters for your RO system. Be sure to select the correct membrane size (listed in GPD or gallons per day). If you have any questions, please call our customer support team at 877-377-9876. We're available Monday through Friday, 9 am to 5 pm Central Time.
Q:
What contaminants will 3M reverse osmosis (RO) systems remove?
A:
3M reverse osmosis systems are designed to tackle a wide spectrum of contaminants commonly found in water. These RO systems can remove chlorine, lead, pesticides, sulfates, fluoride, PFOS, nitrates, pharmaceuticals, Arsenic V, and much more. Furthermore, by forcing water through a semi-permeable membrane, 3M's RO systems can effectively reduce the presence of dissolved solids, ensuring users receive cleaner, clearer, and healthier drinking water. With their advanced filtration technology, 3M RO systems are a trusted solution for households seeking optimal water purity. Many contaminants can be removed with reverse osmosis filtration.
Q:
How often should 3M commercial and residential water filters be replaced?
A:
Most 3M cartridges require replacement every 6–12 months, depending on water quality and usage. High-capacity commercial cartridges may last longer but should be changed when flow drops or taste and odor return.
Q:
How do micron ratings affect the performance of a 3M water filter?
A:
Micron rating determines how finely the filter captures particles. Lower ratings (0.2–1 micron) target fine sediment and cysts, while higher ratings (5+ micron) focus on sediment control. Select a rating based on your water quality needs for your 3M water filtration system.
Q:
What should I do if my 3M filter system has low or slow flow after replacing the cartridge?
A:
Low flow (or slow water flow) may occur if trapped air is in the line, the cartridge isn’t fully seated, or prefiltration is needed. Remove and reinstall the cartridge firmly, flush the system, and ensure incoming water pressure meets 3M’s recommended levels. If you're still having issues, give us a call at 877-377-9876. We're available Monday through Friday, 9 am to 5 pm Central Time.
Q:
What is the difference between 3M HF-series filters and standard sediment or carbon filters?
A:
3M HF-series filters combine sediment reduction, chlorine taste and odor improvement, and high flow capacity in a single cartridge. They are designed for food service equipment where reliability, flow rate, and ease of change-out are priorities.
Q:
How long do 3M water filters last?
A:
Most 3M water filters last 6–12 months, depending on the specific cartridge, water quality, and usage. High-capacity commercial 3M filters may last longer, while residential filters often follow a 6-month schedule. Replace the filter sooner if you notice reduced flow, changes in taste or odor, or if your system’s guidelines recommend a shorter interval.
Q:
How do I know which 3M filter is best for water coolers, ice machines, coffee makers, or beverage equipment?
A:
3M offers application-specific filters optimized for ice clarity, beverage taste, and equipment protection. Choose a cartridge based on required flow rate, scale reduction needs, and the manufacturer’s recommended filtration specs for your equipment.
