Everpure EV960100 filter replacement applies to cold cup vending systems that use a 4C cartridge. The EV960100 6-pack contains six 4C Series cartridges that reduce chlorine taste and odor, fine particles, and cysts in the water supply. Replacing each cartridge on schedule keeps that filtration reliable, which protects both beverage taste and the performance of the vending equipment.
This guide covers when to replace the cartridge, how to prepare, the replacement steps, and what to check once the new cartridge is in.
Why & When You Should Replace the Filter
Each 4C cartridge is rated to treat a set volume of water. Within that rating, it reduces chlorine taste and odor and mechanically filters particles down to 0.5 micron, both covered under NSF/ANSI 42 (Nominal Particulate Class I). It also reduces cysts such as Cryptosporidium and Giardia by mechanical means, covered under NSF/ANSI 53. Once a cartridge is past its rated service life, that performance can no longer be relied on, and the difference shows up in the beverage profile and in the vending equipment on the filtered line.
Everpure recommends replacing the cartridge at least once per year, or before it reaches its rated capacity of 3,000 gallons (11,355 L), whichever comes first. Common signs it's time for an Everpure EV960100 filter replacement:
- The cartridge has reached its 3,000-gallon rated capacity
- About a year has passed since the last replacement
- Water pressure has dropped below 10 psi (0.7 bar)
Slow flow and low pressure are replacement signs on their own. Everpure lists both as reasons to replace the cartridge, even if it hasn't reached a year in service or its rated capacity.
Everpure EV960100 Specifications
The table below lists the key ratings for the EV960100 cartridge, taken from Everpure's 4C cartridge spec sheet. Use it as a reference while preparing for and completing the replacement.
Prepare Your Replacement: Compatibility, Materials & Safety
Verify Filter & System Compatibility
Before any Everpure 4C Series filter replacement, confirm the part number. The EV960100 is the 6-pack of the standard 4C cartridge; Everpure's spec sheet lists it as EV9601-00. The single cartridge is EV960000 (EV9600-00 on the spec sheet).
The 4C2 cartridge (EV960550 single, EV960556 6-pack) is a separate listing with different specifications: 3,950 gallons, 0.2 micron, and NSF/ANSI 42 only. None of the supplied sources confirms that the 4C and 4C2 are interchangeable, so don't assume one can replace the other.
🔍 Not sure which cartridge you have? Check the model tag on the existing cartridge or system before ordering. It should read 4C. Then compare it with the EV960100 product page on BottleFillingStations.com.

⚠️ Safety Precautions
⚠️ Note: Everpure's spec sheet doesn't list any tools for the cartridge change. If your filter head calls for any, follow any instructions packed with the cartridge or filter head.
Step-by-Step Replacement Guide
Signs Your New Filter Is Not Installed Correctly
After installing the new cartridge, check for these signs of an installation problem:
- Leaks at the cartridge connection, fittings, or tubing. Reseat the cartridge using the head's change method, then check each fitting and tubing connection.
- Cartridge not hanging vertically or not fully seated. The 4C cartridge must hang straight down from the head. Remove it and reinstall it so it seats fully in the vertical position.
- Noticeably slow flow or low pressure right after installation. Confirm the cartridge is fully seated. Then confirm the supply pressure is within the range listed in Safety Precautions.
- Sputtering or cloudy water that continues after the flush. Some air and cloudiness are expected during the flush itself (see What to Expect After Installing the New Filter). If either continues after the flush, re-check the seating and connections.
What to Expect After Installing the New Filter
Flush the new EV960100 cartridge at full flow for three minutes before using the water. Everpure calls for a flush at every installation and every cartridge change. During the flush, expect the following:
- Air in the line: trapped air can cause sputtering while it clears.
- Carbon particles: these can show up in the first flush water. They are normal and are the reason for flushing.
- Steady flow afterward: once the flush is complete, the water should run steadily.
If the water is still cloudy or sputtering after the flush, take these steps in order:
- Re-check the cartridge seating and connections.
- Repeat the flush.
- If the problem continues, follow any instructions packed with the cartridge or filter head.
To recap: run the three-minute flush. Then do a quick check for steady flow, no leaks, and pressure within the range listed in Safety Precautions.
Official Installation Reference
Everpure's 4C cartridge spec sheet (EV9600-00) is the official reference for the EV960100. It covers both the single cartridge and the 6-pack. It includes the cartridge's ratings, installation and operation tips, and dimensions.
Maintenance Tips for Longer Filter Life
These routine checks help each EV960100 cartridge perform as rated between replacements:
- Inspect fittings and tubing periodically. Look for leaks, and reseat any connection that isn't secure.
- Stay within the operating limits. Keep pressure, temperature, and flow within the ranges listed in Safety Precautions.
- Keep the cartridge vertical with clearance below. Leave the cartridge hanging straight down from the head, and keep the space beneath it clear for the next replacement.
- Clean exterior surfaces gently. Use a mild, non-abrasive cleaner on exterior surfaces.
- Date each new cartridge. Date each new cartridge with a permanent marker (a common maintenance practice) so the replacement schedule is easy to track.
- Replace on schedule. Follow the interval in the Why & When section above. A cartridge left in service too long can restrict flow to the connected vending equipment.
Where to Buy Genuine Everpure EV960100
Counterfeit or aftermarket cartridges may not carry the NSF/ANSI certifications of the genuine 4C cartridge, and they may not match its original dimensions and fit. Buying genuine is the reliable way to keep the performance the system was set up for.
Purchase the Everpure EV960100 6-Pack from BottleFillingStations.com or another authorized Everpure/Pentair dealer. When the order arrives, confirm that the packaging shows the EV960100 part number and contains six cartridges.
Troubleshooting & FAQ
The new EV960100 cartridge is leaking — what should I check?
The cartridge is most likely not fully seated. Remove it, reinstall it vertically so it seats completely in the head, then check each fitting and tubing connection and reseat any that are loose. See Signs Your New Filter Is Not Installed Correctly for the full list of checks.
The old cartridge is hard to remove.
If your system has a shut-off valve feeding the filter, make sure it's closed, and confirm there is 2.5" (6.35 cm) of clearance below the cartridge. Keep the cartridge vertical as you release it and lower it straight down. If it still won't come free, follow any instructions packed with the cartridge or filter head.
Flow is slow after replacing the EV960100 cartridge.
Check that the cartridge is fully seated and that the water supply is fully restored. Then confirm the operating conditions are within the limits in Safety Precautions. If flow slowed gradually on a cartridge that has been in service for a while, that is a replacement sign; see the Why & When section.
I have a cartridge labeled 4C2 — will it work in place of the EV960100?
Don't assume so. The 4C2 has different specifications from the 4C, and none of the supplied sources confirms that the two are interchangeable. Before any Everpure 4C Series filter replacement, match the 4C tag on your existing cartridge or system and the EV960100 part number. See Verify Filter & System Compatibility for details.
