EV9270-71 is Everpure's part number for the H-300 replacement cartridge. A backorder notice on that number sends shoppers hunting for a substitute. Water Filters FAST has it in stock today at $108.99, and the store also stocks the H-300 HSD cartridge at $115.99.

Those two cartridges are not the same part. One of them belongs in a house with silty water. The other belongs in every other house. Buying the wrong one costs money and solves nothing.

This page separates the two numbers, prices both, and names the water condition that decides between them.

What EV9270-71 actually buys

EV9270-71 is the replacement cartridge for the Everpure H-300 drinking water system. Water Filters FAST lists it as EverPure H-300 Replacement Filter Cartridge - EV927071 or EV927072 at $108.99.

Everpure prints the number two ways. EV9270-71 carries a hyphen and EV927071 drops it. Both strings point at the same cartridge. A parts list that shows one form and a listing that shows the other form have not disagreed about anything.

EV9270-72 sits on the same product page for the same reason. Everpure assigns the second number to the same cartridge, and the H-300 system accepts either one.

The cartridge measures 17 inches long. It runs a half gallon per minute and carries a 300 gallon capacity. The cartridge carries NSF 42 and NSF 53 certification, and the media reduces lead to below the federal action level of 15 parts per billion. It also reduces cysts such as Cryptosporidium and Giardia by mechanical means, plus volatile organic chemicals including THMs.

A scale inhibitor blends into the Micro-Pure media. That inhibitor cuts mineral build-up inside any appliance drawing off the filtered line.

What the H-300 HSD is for

HSD stands for High Silt Density. Water Filters FAST stocks the Everpure H-300 HSD Replacement Water Filter at $115.99, down from a list price of $199.99.

Everpure builds the HSD cartridge to catch silt. A pleated element handles the load a standard cartridge would clog on. The rated capacity still reads 300 gallons at a half gallon per minute, and the certifications still read NSF/ANSI 42 and 53.

The Water Filters FAST product page carries Everpure's own guidance on this cartridge. Most customers do not need the silt feature and should order the standard H-300 cartridge. Everpure put that sentence on the part because the HSD looks like an upgrade and is a specialty item.

Well water with visible cloudiness is the case that justifies it. So is a house on a rural line that runs dirty after a main break. City water that comes out clear does not need a silt cartridge.

How Everpure numbers its parts

Everpure part numbers open with EV, run four digits, take a hyphen, and close with two more digits. EV9270-71 breaks down that way. The first block identifies the product family and the last block identifies the specific item inside it.

The H-300 family shares the EV9270 block. The cartridge reads EV9270-71 and the complete system reads EV9270-76. Two parts, one family, and a single pair of digits between them.

That similarity causes the most expensive mistakes on this line. A shopper who wants a $108.99 cartridge and types the system number lands on a $249.99 listing. A shopper who wants the complete system and types the cartridge number gets a cartridge with no head to screw it into.

Read the last two digits before ordering. Seventy-one buys a cartridge. Seventy-six buys the whole system with a cartridge already in it.

Other Everpure families follow the same rule. The H-54 cartridge reads EV9252-68 and the H-104 system reads EV9262-71. Nothing in the digits tells you which one is a cartridge and which one is a system, so the product title carries that job.

Which cartridge your system takes

The system housing decides this, and Everpure prints the answer on it. Read the label on the metal head your cartridge twists into. A head stamped H-300 takes the EV9270-71 cartridge. A head stamped H-300-HSD takes the HSD cartridge.

Pull the old cartridge and read the number printed near the top if the head label has worn off. That number is the one to reorder.

Call 855-789-FAST when the label is gone and the cartridge is already in the trash. The filter experts will work back from the system model.

The H-300 system itself

Water Filters FAST stocks the Everpure H-300 Drinking Water System EV9270-76 at $249.99. The system arrives as a head, a mounting bracket, and one cartridge.

It stands 22 inches tall and measures 5 inches across, so it needs a clear run under the sink. A built-in shut-off valve makes cartridge changes clean. The system filters to half a micron and holds a 300 gallon rating.

Everpure wraps the cartridge in a metal canister. The system listing calls that canister the reason the filter resists splitting or bursting, and it describes the whole unit as commercial grade filtration.

The rest of the Everpure residential line

Four Everpure cartridges cover most homes. Each one fits its own head, and none of them interchange.

Capacity and price move in opposite directions across that table. The Everpure H-54 cartridge costs the least and runs the longest at 750 gallons. The H-300 costs more than either of those and stops at 300 gallons.

That gap reflects what each cartridge removes. The H-300 media reduces asbestos fibers, chloramine, mold and algae on top of the lead and cyst reduction the H-54 shares. Heavier media fills faster.

Every cartridge above ships from the same warehouse. Browse the full Everpure collection for the commercial and foodservice cartridges as well.

How often the H-300 cartridge gets changed

Everpure sets a yearly interval on the H-300 cartridge. The HSD listing gives a range of six to twelve months, because silt loads the element faster.

Capacity is the other limit. A household drawing more than 300 gallons through the filter in a year hits the rating before the calendar does. A family of four that drinks and cooks off the filtered tap will get there.

Flow tells you when the date and the gallon count both look fine. A filtered faucet that used to fill a pitcher steadily and now runs thin has a loaded cartridge. Change it and the flow returns.

Mark the install date on the canister with a permanent marker. The metal takes ink and holds it for a year.

Changing an H-300 cartridge

Everpure compares the swap to changing a light bulb, and the comparison holds. The cartridge twists out of the head and the new one twists in. No wrench and no tools.

Close the built-in shut-off valve on the head first. Run the filtered faucet for a few seconds to bleed off the line pressure. Turn the old cartridge a quarter turn and pull it straight down.

Line the new cartridge up with the head and turn it the other way until it seats. Open the shut-off valve and watch the connection for thirty seconds.

Run the filtered faucet for five minutes before drinking. Fresh carbon sheds a fine grey dust on the first draw, and the flush clears it. Gray water at the start is normal and it clears on its own.

Scuffs and small dents on the aluminum shell arrive from the factory that way. Everpure notes on the listing that these marks are cosmetic and do not affect how the cartridge performs.

What a fresh cartridge will not fix

A new cartridge restores flow and taste on the filtered line. It does nothing for the rest of the house.

Cloudy water at the kitchen tap and the bathroom tap together points upstream of the filter. So does a sulfur smell in the hot water only, which usually traces to the water heater anode rod.

An under sink system treats one faucet. Whole house problems need a whole house answer, and the under sink water filter collection shows where that line falls.

Ordering, shipping, and returns

Water Filters FAST ships weekday orders the same day when they land before 1pm CST. Orders over $75 ship free, and both H-300 cartridges clear that line on their own.

Returns run 30 days. A satisfaction guarantee backs every cartridge in the catalog.

Order the standard EV9270-71 cartridge if the head reads H-300 and the water runs clear. Order the HSD if the head reads H-300-HSD or the water carries visible silt. Call 855-789-FAST if neither sentence describes your situation.

Can the H-300 HSD replace a standard H-300 cartridge?

The HSD is built for high silt water and it costs $7.00 more. Everpure's own guidance on the Water Filters FAST listing directs most customers to the standard H-300 cartridge.

How long does an Everpure H-300 cartridge last?
