Brita Replacement Filter: Thirteen Cents a Gallon, Forty Gallons a Cartridge
The Brita replacement filter in the three pack is the cheapest gallon in our pitcher records at about 13 cents. The Original cartridge is rated 40 gallons or about 2 months, and Brita names chlorine for taste and odor plus copper, cadmium and mercury as the reductions. Our record for the listing carries NSF/ANSI 42 and the standard number is not printed on the box, the listing or the product page. It sat at rank 1 in Replacement Pitcher Water Filters the day we last checked, which makes it the most bought cartridge we cover.
Brita Replacement Filter Specs: What a 40 Gallon Cartridge Covers
The Brita replacement filter in this three pack is the Original cartridge, model OB03, and it fits every Brita jug and dispenser apart from the Stream. It is the consumable that made the brand, and it is the one most households buy without reading anything.
Forty gallons, about two months, and a rinse under the tap before it goes in. For how it compares with the rest of the aisle, our replacement cartridge comparisons hold the running list, and the rest of the Brita range shares the same body fit.
- Certification: our record for this listing carries NSF/ANSI 42 alone, and Brita's own Performance Data Sheet contradicts the record: the sheet for this cartridge, model OB03, states the system was tested to NSF/ANSI 42 and NSF/ANSI 53. The listing says only WQA NSF/ANSI certified and the product page prints no standard at all, so the numbers live in one PDF and nowhere on the box.
- Named reductions: Brita lists chlorine for taste and odor, copper, cadmium and mercury. There is no lead claim on this cartridge; Brita reserves that for the Elite filter in the same housing.
- Rated capacity: 40 gallons per cartridge, or about 2 months, and Brita notes that hard water shortens the interval.
- Media: coconut based activated carbon plus ion exchange resin in a housing made without BPA, which Brita says preserves healthy minerals and leaves a healthy level of fluoride in the water.
- What the sheet measures: under standard 42 the sheet records chlorine at 95 percent and zinc at 64 percent. Under standard 53 it records cadmium at 91 percent at pH 6.5 and 94 percent at pH 8.5, copper at 89 percent and 73 percent, and mercury at 86 percent and 82 percent. No lead number, no asbestos, no volatile organic compounds and no 401 list. That is the whole certified list, and it is the shortest one any pitcher cartridge in our records publishes.
- Cartridge size and weight: 4.12 by 2.31 by 2.31 inches and 0.13 pounds, model OB03. That is a little over two ounces of media and housing doing the whole job.
- Install: rinse under cold water for 15 seconds, drop it in, and discard the first three pitchers of water. No presoak, no tools, no soaking overnight.
- Fit: every Brita pitcher and dispenser except the Stream, which is the same fit statement the Elite cartridge carries.
- Pack sizes: sold singly and in packs up to six. This page prices the three pack, which is the listing the catalog resolved.
- Flow rate: not published, by Brita for the cartridge or by the listing for the pitcher it goes into.
- Guarantee: a 30 day unconditional money back guarantee on Brita filters, per the listing's own warranty statement.
- Price band: $14 to $17 for the three pack at our last check, in stock, sold and shipped by Amazon.com, buy box winner. That is about $5 per cartridge. Brita's own store lists the same three pack in the $18 to $19 band, so the listing is the cheaper route and the manufacturer is not pretending otherwise.
- Not published: a certificate or listing number and a flow rate. Those two absences cost this cartridge Nerd Stamp points below.
What that adds up to at your tap: a cartridge that goes in after fifteen seconds of rinsing, takes the chlorine out of the jug for about eight weeks, keeps the fluoride in, and costs about five dollars and change per cartridge in this pack.
Forty gallons is 640 eight ounce glasses, and one cartridge is about a sixth of a household year. At the 240 gallons a year Brita publishes for a household, that is six cartridges, which is $28 to $34 on this band. The three pack looks like the cheap answer and the yearly column is where you find out whether it is.
Think of it this way
A cartridge that weighs 0.13 pounds holds 40 gallons of drinking water, which is 640 eight ounce glasses and about 320 pints. Two ounces of carbon and resin against a year of jug refills is the whole reason this cartridge family still outsells everything else on the shelf. The clever part was never the filter. It was the fit.
Brita Replacement Filter Score: 4 of 7
Every product in this index is rated 1 to 7 across seven verifiable criteria. One point per criterion. No partial credit. I am an enthusiast with a long memory and a spreadsheet, not a lab, and the scorecard below is the published rubric in one table.
Each line asks two questions: is the number on the record, and does it hold up against the rest of the class. The line stays at zero when the document is missing or the figure is the worst in its class. Three of the seven lines sit at zero, which is 3 of the 7 points, and the first of them is the certificate number this cartridge never prints.
| Criterion | Points | Evidence |
|---|---|---|
| Certified removal scope | 0 points | Chlorine, zinc, cadmium, copper and mercury are the whole certified list, published on the sheet under 42 and 53, and there is no lead claim while the Elite cartridge in an identical body carries lead |
| Certification and test transparency | 0 points | The data sheet prints standards 42 and 53, and names no certifying body and no certificate or listing number |
| Filter life and rated capacity | 1 point | 40 gallons and 2 months, both published, which is six cartridges in a household year |
| Cost per gallon | 1 point | About 12 to 14 cents on the three pack, the cheapest certified pitcher gallon in our records |
| Flow rate and pressure drop | 0 points | No flow rate published for the cartridge or the pitcher, while ZeroWater publishes 6.5 ounces a minute |
| Install and footprint | 1 point | A 15 second rinse and it drops in, no presoak, no tools, and it fits every Brita body except the Stream |
| Maintenance burden | 1 point | Six changes a year at Brita's household figure, twice the Elite interval and a quarter of the ZeroWater one |
Three lines sit at zero, and the first is the list that stops early. The data sheet does print the standards, 42 and 53, with a percentage beside each substance. What it does not print is a number a reader can look up, and what the list does not carry is lead. Our own record carries 42 alone, which the manufacturer's own sheet contradicts, and the sheet is the better document of the two.
The flow line is the same missing sentence, and it is worth 1 of the 7 points on its own. ZeroWater publishes a 6.5 ounce a minute trickle and collects the point for honesty. Brita publishes nothing, so there is nothing to measure.
Who the Brita Filter Fits
The question is never which filter is best. It is which filter matches your tap, your jug, and the contaminant you actually named before you started shopping. This cartridge answers the chlorine question for about 13 cents a gallon and answers the lead question by not making the claim.
Pick your side. If lead is the reason you are buying, the Elite cartridge in the same body is the one to price, and the pitcher filter rankings compare the two.
- The taste and odor household: chlorine is what 42 covers, and this is the cheapest certified route to better tasting water in the index.
- The jug you already own: the cartridge fits every body but the Stream, so the jug does not need replacing.
- The low maintenance household: a 15 second rinse and it drops in, with no overnight soak and no tool.
- The fluoride keeper: Brita says the resin leaves a healthy level of fluoride in the water, which matters if your utility adds it deliberately.
- The three pack buyer: six months of cartridges in one order, which is the smallest sensible purchase for a household at the manufacturer's usage figure.
- The budget household: this is the pick on our budget water filters shortlist, and at about five dollars a cartridge it earns the place.
This Is Not Your Cartridge If
- You need lead reduction. Brita reserves the 99 percent lead claim for the Elite filter, and this cartridge does not carry it.
- You drink more than 240 gallons a year. Six cartridges a year becomes eight or nine, and the pack math changes with it.
- You are on hard water. Brita says the interval shortens, so the 40 gallon rating is a ceiling rather than a promise.
- You want a certificate number you can check. It is not on the box, the listing, the product page or the data sheet.
- You want the fewest changes a year. The Elite cartridge lasts three times as long in the same body for about the same annual money.
The way I see it
This is the printer cartridge argument with water in it. A branded three pack on one side, a six pack that copies the fit on the other, and most of the price difference, about two dollars a cartridge, is the badge rather than the carbon. The interesting part is that the badge here is the cheap option, and the copy is cheaper still.
Brita Filter Pros and Cons
What You Get
- The cheapest certified pitcher gallon in our records: about 12 to 14 cents, against 100 to 120 cents for a ZeroWater cartridge.
- A fit that needs no thinking: every Brita jug and dispenser apart from the Stream takes it.
- Fifteen seconds to install: rinse, drop in, discard the first three pitchers, done.
- Fluoride and minerals kept: the resin leaves the additive in, which is unusual in this category.
- Six months of cartridges in one order: the three pack at about five dollars a cartridge is a small commitment.
- A real guarantee: 30 days, unconditional, on Brita filters per the listing's warranty line.
What It Costs You
- Six cartridges a year: at Brita's household figure, which is three times the Elite interval.
- 40 gallons a cartridge: the lowest rated capacity in the Brita family, and a sixth of a household year.
- No lead claim: lead is the Elite's job in this ecosystem, and this cartridge does not carry it.
- No certificate number: the data sheet names the standards, and nothing on any surface names the certificate.
- No flow rate: the number this category most often publishes is absent here too.
- Hard water shortens it: the interval moves up while the rating stays at 40 gallons.
Brita Filter Cost Per Gallon
About thirteen cents a gallon is the cheapest certified pitcher water in our records, and the yearly column is where that stops feeling like the end of the story. I have run this arithmetic across every cartridge in the index, and the Original and the Elite land within a few dollars of each other across a year: six cheap cartridges against two expensive ones, for about the same money. Our replacement cartridge comparisons exist to make that visible before you buy rather than after.
- The pack: a $14 to $17 band for the three pack at our last check, which is about $5 per cartridge.
- The charted figure: about $5 a cartridge divided by 40 gallons is about 12 to 14 cents per gallon.
- The annual column: 6 cartridges at the 240 gallon household volume is about $28 to $34 a year, roughly 8 to 9 cents a day.
- The Elite cartridge in the same body: about $16 to $20 each at 120 gallons, so two a year is about $32 to $40. That is the same annual money for a third of the changes.
- The aftermarket option: a six pack in our records sits in the $15 to $19 band, which is about $3 per cartridge. It is cheaper per unit and it has no filter life recorded, so this site cannot score it.
- The same math on a ZeroWater cartridge: $15 to $18 at 15 gallons, which is about 100 to 120 cents per gallon and something like sixteen cartridges for a household year.
Here is the part the price tag hides: a cartridge that costs a third as much and lasts a third as long is not a cheaper cartridge. Six of them against two of the long one is about the same annual bill, roughly $32 to $40 a year, with four extra rinses and four extra pieces of plastic for the privilege. The annual column is where the three pack stops looking like the frugal answer and the Elite starts looking like free labour.
For the intervals by filter type rather than by brand, the replacement schedule lays the whole grid out.
Think of it this way
Six cartridges a year at about five dollars each, against two cartridges a year at about eighteen dollars each, is roughly the same annual bill. One of those options has you rinsing a cartridge by the sink four extra times a year. Thirteen cents a gallon is genuinely cheap water. It is not the cheapest way to spend the year.
Six cartridges in a year, or two if you move up to the Elite in the same body.
Brita Replacement Filter vs the Field
Every row below is a cartridge from our own index, with the certification and the rated life taken from our records. Nothing here is a manufacturer comparison chart, and the figures are bands rather than live prices.
| Cartridge | Certified | Rated life | Price per cartridge |
|---|---|---|---|
| Brita Original 3 pack | NSF 42 in our record | 40 gal | about $5 |
| AQUA CREST 6 pack | NSF certified | not recorded | about $3 |
| Brita Elite | 42, 53, 401 in its sheet | 120 gal | $16 to $20 |
| PUR Plus 3 count | NSF 42, 53 | 40 gal per cartridge in the pitcher range | $9 to $11 |
| Clearly Filtered 3 pack | NSF 42, 53, 372 | 100 gal | $58 to $65 |
Two things stand out. First, the NSF certification explainer is the page to read before choosing any of these rows, because two of the certificates here are described in the listing as certified without naming a standard, and one names 42, 53 and 372 outright. A certificate you cannot read is a certificate you cannot compare.
Second, the aftermarket six pack undercuts the branded cartridge by about two dollars a unit and carries no rated life in our records, which is exactly the field that turns a product from writable into a research project on this site. Its per gallon figure cannot be computed and the page will not guess at it.
You are choosing between a cheap certified gallon and a wider certificate. This cartridge wins the first and politely declines the second, and it does not even print what its own certificate says.
Same fit, 120 gallons a cartridge, and the lead claim this pack does not make.
Brita Replacement Filter FAQ
- Does the Brita replacement filter remove lead?
- Not this one. Brita names chlorine for taste and odor plus cadmium, copper and mercury on the Original cartridge and reserves the 99 percent lead claim for the Elite filter, which fits the same pitchers. If lead is your reason, price the Elite and expect about three times the cartridge life for about three times the unit price.
- How often do I change a Brita Original filter?
- 40 gallons, or about 2 months, with Brita noting that hard water shortens the interval. At 240 gallons a year, the household volume Brita publishes, that is six cartridges, so a three pack is six months of water and a six pack is a year.
- Is the three pack the same cartridge as the six pack?
- Yes, it is the same Original cartridge in a bigger box, and the pack is where the price difference lives. The six pack in our records sits near $3 per cartridge, against about $5 in the three pack, so the bigger box is the cheaper unit if you will use them.
- Will an aftermarket cartridge work?
- Aftermarket packs are built to fit Brita pitchers, and the one in our records undercuts the branded cartridge by about two dollars a unit. It carries no rated life figure in our catalog, and this site does not compute a cost per gallon without one, so the comparison stops where the documentation stops.
- What is the filter certified to?
- The listing says WQA NSF/ANSI certified and prints no standard number. Brita's own Performance Data Sheet for the cartridge, model OB03, states it was tested to NSF/ANSI 42 and NSF/ANSI 53, with chlorine at 95 percent and zinc at 64 percent under 42 and cadmium, copper and mercury under 53. Our record for this listing carries NSF/ANSI 42 alone, so the sheet is the document to trust. No certificate or listing number is published anywhere. The certification explainer walks through what 42, 53 and 401 each cover.
Brita Replacement Filter: Where It Lands, Cheap Gallons and a Blank Certificate
The Brita replacement filter earns 4/7, and the three zeros are one missing certificate and two gaps in the record. It is rated 40 gallons and about 2 months, fits every Brita body except the Stream, drops in after a 15 second rinse, and works out at about 13 cents per gallon in the three pack.
Its certified list reads chlorine, zinc, cadmium, copper and mercury across 42 and 53, which the sheet publishes, and it still offers no certificate number to look up and publishes no flow rate at all. Three points lost to a gap in the paperwork, and four points earned on price, fit and life.
Buy it if chlorine is the complaint and the jug is already on the counter. If the annual column is what you are shopping by, the long life cartridges in our records cost the same per year and ask for a third of the changes.
Cheapest certified pitcher gallon we carry, blankest certificate in the family, and both are on the record.
Where It Lands: Thirteen Cents and a Blank Label
Forty gallons a cartridge, six in a household year, about five dollars each, and a fit that needs no thought. No certificate number and no flow rate are the two lines that hold it to 4/7.
Brita Filter Lexicon: Every Standard in This Review
- NSF/ANSI 42
- The aesthetic effects standard, and one of the two this cartridge's data sheet names. It covers the chlorine that makes water taste and smell like a pool rather than anything about health.
- NSF/ANSI 53
- The health effects standard. It covers lead, chromium, mercury and, since PFOA and PFOS were added, the two most studied PFAS compounds. This cartridge's sheet lists copper, cadmium and mercury under it, and the pack itself says nothing.
- NSF/ANSI 372
- The lead-free materials standard, about the hardware rather than the treatment. It appears on premium cartridges in our records and not on this one.
- Ion exchange resin
- The media that swaps unwanted ions for ones it would rather release, and the reason a carbon cartridge can claim copper, cadmium and mercury at all.
- Activated carbon
- Coconut based carbon in this cartridge, which is what pulls chlorine and taste compounds out of the water. The media sets both the flow and the rated life.
- Rated capacity
- The volume a cartridge filters before performance is no longer certified, in gallons. This one is 40, and the interval beside it is about 2 months.
- Fluoride retention
- Brita states the resin leaves a healthy level of fluoride in the water. Most pitchers neither add nor remove it, and reverse osmosis does remove it.
- Aftermarket cartridge
- A third party copy built to fit a branded pitcher. It is usually cheaper per unit, and it is where a catalog tends to run out of documentation such as a rated life figure.
- Performance Data Sheet
- The document that ties a reduction claim to a standard and a result. On this cartridge it records standards 42 and 53 with a percentage beside each substance, and it is also where the trail stops, because no certificate number follows.
