Everpure Compatible Filters Guide: H-1200, H-300 NXT, and Full Cartridge Lineup for 2026

Everpure is the residential cartridge brand that combines foodservice-grade filtration with quick-change residential convenience. Manufactured by Pentair, the Everpure lineup is widely installed in kitchens, offices, coffee bars, and small foodservice setups where consistent water quality is non-negotiable. If your home or office uses an Everpure system, the replacement cartridge decision matters because the wrong cartridge fits the wrong head, and a mismatch means a return and another wait.

This guide breaks down the active Everpure residential cartridge lineup, the difference between the H-300 and the higher-performing H-300 NXT, and how subscribe-and-save scheduling keeps Everpure-system owners ahead of the replacement cycle.

The Active Everpure Cartridge Lineup

Everpure produces several point-of-use cartridges aimed at different residential and light-commercial use cases. The four most commonly ordered cartridges:

Cartridge	OEM Number	Capacity	Best Use
H-300 NXT	EV9275-15	300 gal	Premium residential single-tap, upgraded filtration
H-1200	EV9282-00	1,500 gal	Whole-kitchen or multi-tap residential
H-54	EV9252-67	750 gal	Mid-volume residential with scale reduction
H-104	EV9612-11	1,000 gal	Higher-volume residential and light commercial

Each Everpure cartridge fits a dedicated head assembly. The H-300 NXT does not fit an H-1200 head, the H-1200 does not fit an H-54 head, and so on. The cartridge connection is keyed specifically to each head type.

The H-300 NXT vs the Original H-300

The original Everpure H-300 (EV9270-71) is the predecessor cartridge that the H-300 NXT replaced. While the H-300 remains in production for the installed base of older systems, the H-300 NXT is the current production standard for new installs and is the recommended upgrade for older H-300 systems.

The H-300 NXT delivers:

• Upgraded carbon filtration media
• Improved chlorine and chloramine reduction
• Enhanced lead reduction profile
• Same 300-gallon capacity, same 6-month replacement interval
• Same head fitting as the original H-300

For Everpure system owners running an original H-300, upgrading to the H-300 NXT is a drop-in improvement with no system modification required. The H-300 NXT fits the same head assembly and provides upgraded filtration without changing the replacement schedule.

Everpure H-300 NXT

The H-300 NXT is the residential standard for Everpure systems. Most under-sink Everpure installations use this cartridge.

The H-300 NXT is the right choice for households running an Everpure system on single-tap drinking water with typical residential volumes.

Everpure H-1200

The H-1200 is the highest-capacity cartridge in the residential Everpure lineup. Designed for whole-kitchen filtration or multi-tap residential setups, the H-1200 delivers 1,500 gallons of filtered water between replacements.

Quick Specs

When the H-1200 Is the Right Choice

The H-1200 is the cartridge for:

• Whole-kitchen filtration where filtered water feeds the main sink, the refrigerator, and the dedicated drinking faucet
• Multi-tap residential setups with high daily filtered water usage
• Office break rooms with multiple users and high daily water consumption
• Households that prefer the longest possible interval between cartridge attention

The H-1200 carries the same NSF 42 and 53 certifications as the H-300 NXT. The difference is capacity, not the contaminant reduction profile.

Everpure H-54 and H-104

The H-54 and H-104 fill specific use cases between the H-300 NXT and the H-1200.

H-54 (EV9252-67)

The H-54 carries 750-gallon capacity and adds polyphosphate scale reduction for hard-water households. The scale reduction protects downstream equipment like coffee machines and ice makers from mineral buildup. The H-54 is the right cartridge for residential setups in hard-water regions where scale prevention matters in addition to taste and odor reduction.

H-104 (EV9612-11)

The H-104 carries 1,000-gallon capacity for higher-volume residential and light-commercial use. Office break rooms with single dispensers, coffee shops with one espresso machine, and households with above-average filtered water consumption are typical H-104 applications.

How to Replace an Everpure Cartridge

The replacement procedure is similar across all Everpure quick-change cartridges. Total time is under five minutes. No tools required.

1. Turn off the water supply to the Everpure head. Most installations have a dedicated shut-off valve on the cold line going into the head.
2. Open the faucet that the filter feeds to release pressure in the cartridge.
3. Rotate the existing cartridge a quarter turn counter-clockwise. The cartridge will release from the head.
4. Pull the cartridge straight down and set it aside. A small amount of water will drain. A towel under the head catches most of it.
5. Take the new cartridge out of packaging and remove the protective cap from the top. Inspect the O-ring for debris.
6. Align the new cartridge with the head, push up into position, and rotate clockwise a quarter turn until it stops.
7. Open the water supply valve slowly. Watch for leaks at the head connection.
8. Flush the new cartridge by running 2 to 3 gallons of water through the connected fixture. Discard this water to clear carbon fines.
9. Mark the install date on the cartridge body with a permanent marker. Six months from today is your next replacement date.

Total time: about four minutes once the new cartridge is in hand.

When to Replace an Everpure Cartridge

All Everpure residential cartridges replace every 6 months or at the rated gallon capacity, whichever comes first. For most residential households, the 6-month calendar interval is the binding constraint.

Signs the cartridge is past due:

1. Reduced flow at the dedicated faucet
2. Returning chlorine taste or odor in filtered water
3. Date on the cartridge label showing more than 6 months since install
4. System bypass indicator (some Everpure heads have an integrated indicator)

Running an exhausted cartridge does not damage the system. The cartridge simply stops filtering effectively. For households running Everpure specifically for taste and contaminant reduction, replacing on schedule preserves the value of the system.

Subscribe and Save: Built for Everpure Owners

Everpure systems are typically a 10 to 15 year investment in residential water filtration. The cartridges replace every 6 months across that lifetime, which means 20 to 30 individual ordering decisions if you order one-at-a-time.

The subscription model collapses those decisions into a single setup. Every 6 months, a fresh cartridge arrives a few days before the install date with email reminders if you want them. Skip, pause, or cancel any shipment without penalty. The subscribe-and-save discount applies to every cartridge in the residential Everpure lineup.

For multi-cartridge setups (H-1200 in the kitchen plus an H-300 NXT in a second location, for example), coordinated subscription delivery ensures all cartridges replace on schedule.

Authentic vs Aftermarket Everpure Cartridges

Pentair manufactures the genuine Everpure cartridges. Aftermarket alternatives exist but vary in NSF certification, carbon density, and O-ring fit quality.

Things to verify on any aftermarket cartridge:

• NSF 42 and 53 certification on the packaging
• O-ring dimensions matching the Everpure head specification
• Carbon block density matched to the cartridge's flow rate
• Manufacturer reputation for consistent quality

For Everpure cartridges specifically, OEM is strongly recommended. The aftermarket gamble on a $30 to $80 cartridge is not worth a potential leak under your sink, a flow restriction that reduces system performance, or a cartridge that fails to deliver NSF-certified filtration.

Frequently Asked Questions

What is the difference between H-300 and H-300 NXT?
Both cartridges fit the same Everpure head and share the same 300-gallon capacity. The H-300 NXT uses upgraded carbon filtration media for improved chlorine, chloramine, and lead reduction. The H-300 NXT is the current production standard and the recommended upgrade for any system originally running the H-300.

Can I install an H-1200 cartridge in an H-300 system?
No. The H-1200 and H-300 NXT use different head assemblies. The cartridge connections are keyed specifically to each head. To upgrade from an H-300 NXT setup to an H-1200, you need to replace the head assembly along with the cartridge.

How long does an Everpure cartridge actually last in residential use?
Six months on the calendar for all residential Everpure cartridges. The gallon capacity is rarely the binding constraint in normal residential use. The 6-month interval matters for taste, odor, and contaminant reduction consistency.

Does the H-300 NXT remove fluoride?
No. The H-300 NXT reduces chlorine taste and odor, chloramine, particulates, cysts, and lead. Fluoride removal requires a reverse osmosis system.

Why are Everpure cartridges more expensive than some refrigerator filters?
Everpure cartridges use foodservice-grade carbon density and NSF-certified materials throughout. The H-1200 in particular delivers 1,500-gallon capacity in a single cartridge, which is 5 to 8 times the capacity of a standard refrigerator filter. The cost per filtered gallon is competitive when measured across the cartridge lifetime.

Can I subscribe to multiple Everpure cartridges at different intervals?
Yes. Subscriptions can be set up per cartridge with coordinated delivery dates. Multi-cartridge subscriptions also stack the subscribe-and-save discount across all cartridges in the subscription.

Is the H-300 still in production?
Yes. The H-300 remains in production for the installed base of older Everpure systems. Pentair continues to manufacture the cartridge. For new orders, the H-300 NXT is the recommended upgrade.
