Everpure Water Filter Cross-Reference Chart: All Models & Compatible Replacements (2026)

Everpure (now part of Pentair) is one of the most widely installed commercial water filtration systems in the world. Walk into almost any restaurant, coffee shop, hotel, or convenience store in North America and you will find an Everpure head unit on the wall — feeding an ice machine, an espresso machine, a fountain dispenser, or a combi oven.

The system’s genius is also its cost trap: the head stays permanently plumbed in, but the cartridge must be replaced every 6 months (or sooner at high volume). Original replacement cartridges typically retail between $60 and $180 each. For a chain with dozens of locations — or a distributor supplying hundreds of restaurants — cartridge replacement is a five- or six-figure annual line item.

This guide is a complete cross-reference chart for the most common Everpure cartridge models: what each one is, which head systems it fits, and which compatible replacements exist. Bookmark it — it covers every model you’re likely to encounter in the field.

How the Everpure System Works

Every Everpure installation has two parts:

1. The head (manifold) — permanently installed, connected to the water line. Single, twin, and triple configurations exist. The head almost never needs replacement.
2. The cartridge — screws into the head with a quarter-turn bayonet fitting. This is the consumable part.

Because the bayonet interface is standardized, any cartridge with the same fitting, diameter, and length is physically interchangeable on the same head. This is what makes compatible (generic) replacements possible: a properly built compatible cartridge with the same dimensions, the same coconut-shell carbon block media, and NSF-certified materials performs the same filtration job.

There are three cartridge lengths that cover roughly 70% of the installed base:

Length class	Dimensions (D × L)	Typical Everpure models
10-inch	79 × 260 mm	MC2, MCS2, 4C, 4FC, 4FC-S
15-inch	79 × 371.7 mm	H-104, H-54, H-100, BH2
20-inch	79 × 514.7 mm	H-300, H-300-NXT, i2000, i4000

How to Identify Which Everpure Cartridge You Have

If the label is worn off (common in humid back-of-house environments), identify the cartridge in three steps:

1. Measure the length. From the head interface to the bottom of the cartridge: ~260 mm = 10-inch class, ~372 mm = 15-inch class, ~515 mm = 20-inch class.
2. Check the application. Feeding an ice machine? It’s almost certainly an i2000/i4000 (20”) or an MC2 on smaller installs. Feeding coffee/espresso? Usually 4C/4FC. Undersink residential? H-54/H-104/H-300.
3. Look at the head. Single heads in foodservice usually carry MC2 or i2000-class cartridges; twin and triple heads at high-volume sites usually carry i4000 or 4FC-class cartridges plus a scale inhibitor feed.

Original vs. Compatible: The Cost Math

	Original (retail)	Compatible (factory-direct)
Typical unit price	$60–180	30–50% below original
Media	Carbon block	Coconut-shell carbon block
Materials	NSF-certified	NSF-certified
Fitting	Bayonet quarter-turn	Identical bayonet quarter-turn
MOQ	—	From 200 pcs
Private label	No	Yes — your brand, your packaging

For a distributor moving 1,000 cartridges a month, switching to compatible replacements typically saves $30,000–80,000 per year at identical filtration performance. Many of our OEM customers sell compatible cartridges under their own brand at 20–30% below original retail — undercutting the original while carrying a higher margin than reselling originals.

Frequently Asked Questions

Are compatible Everpure replacement cartridges safe?

Yes — provided they are manufactured with NSF-certified food-contact materials and proper carbon block media. The filtration function comes from the media and construction, not the brand name. Always ask the manufacturer for material certifications (NSF, FDA) and factory audit reports before ordering.

Will a compatible cartridge fit my existing Everpure head?

If the cartridge matches the model class in the chart above, yes. The bayonet quarter-turn interface is dimensionally standardized. XZH compatible cartridges are produced against engineering drawings of the original interface and batch-tested for fit and leak-free sealing.

Do compatible cartridges void the ice machine warranty?

Equipment warranties (Hoshizaki, Manitowoc, Scotsman, etc.) require that the machine be supplied with properly filtered water — they specify water quality parameters, not a specific filter brand. Using a compatible cartridge that delivers the same filtration does not change the water quality delivered to the machine. Check your specific warranty terms; see also our ice machine water filter guide.

How often should Everpure-class cartridges be replaced?

Every 6 months, or when rated capacity is reached — whichever comes first. High-volume sites (busy QSRs, hotels) often hit capacity in 3–4 months. Flow drop and taste change are the practical replacement signals.

What is the minimum order for factory-direct compatible cartridges?

MOQ starts at 200 pieces per model at Ningbo XZH, with mixed-model containers possible. Private-label packaging (your brand, your box, your label) is available on all models. Request a quote with your model mix and monthly volume for a landed-cost estimate.

Summary

• Everpure heads are permanent; cartridges are the recurring cost — $60–180 each at retail, replaced every 6 months.
• Three cartridge sizes (10” / 15” / 20”) cover ~70% of the installed base; the chart above cross-references every common model.
• Compatible replacements with identical dimensions, NSF-certified materials, and coconut carbon block media cost 30–50% less factory-direct — and can carry your own brand.
