Brita Faucet Mount Filter: Three Standards, One Twist
The Brita faucet mount sits at the cheap end of the faucet aisle on running cost, and it's one of only two faucet filters in the index whose own data sheet publishes a flow rate. That sheet certifies the system by WQA against NSF/ANSI 42, 53 and 401, at 100 gallons a cartridge and a service flow of 0.58 gpm. It sat at rank 2 in Faucet Mount Filters the day we last checked.
Brita Faucet Mount Water Filter Specs: 0.58 GPM and Three Standards
The Brita faucet mount is a cartridge in a cup that screws onto the end of a standard spout, and the water is filtered as you draw it. The system sells as model FF-100 or SAFF-100 depending on the colorway, and the cartridge inside it is model FR-200.
A pitcher holds a reservoir of 2 liters or more that has to be filled and then stands in the fridge. This system holds nothing: a housing, a cartridge and a diverter you flip with a thumb, all drawing at 0.58 gpm. For where it sits against the rest of the aisle, our faucet mount filter rankings hold the running list, and the rest of the Brita lineup covers the jugs and the dispensers.
- Certification: the data sheet states that the system has been certified by WQA against Standards 42 and 53, and against the 401 emerging compounds list, for the reduction of the contaminants specified on the sheet. Three standards in one certification is the widest claim in our faucet mount records, and the two rivals that carry 401 at all are in a different price tier.
- Certified reductions, with numbers: under Standard 42 the sheet records chlorine at 99.0 percent and nominal particulate Class I at 99.9 percent. Under Standard 53 it records lead at 99.9 percent on a 0.15 mg/L challenge, against a 0.005 mg/L product water limit, at pH 8.5 and at pH 6.5. Under Standard 401 it lists the emerging compounds table. brita.com adds asbestos, benzene and trichloroethylene to the reduced list.
- Rated capacity: 100 gallons, or 378 liters, which is the figure the certification is written against. Brita frames the same cartridge as up to 4 months for most households.
- Service flow rate: 0.58 gpm, or 2.19 liters a minute, and it's a published number rather than a marketing adjective. That's about 74 ounces a minute, so an 8 ounce glass takes under 7 seconds of filtered flow.
- Working pressures: 20 psig to 100 psig, with performance testing done at 60 psig. A tired municipal line at the bottom of that range still passes water, and a house at the top of it does not blow the housing off.
- Cartridge size and weight: 4.28 by 2.38 by 4.75 inches and 0.64 pounds, model FR-200. It is a housing the size of a small drinking glass and about the weight of a paperback novel.
- Interval and prep: replace at 100 gallons or about 4 months, and run 5 minutes of water through a new cartridge before the first glass. At 0.58 gpm that flush costs roughly 3 gallons, and Brita says the 100 gallon clock starts after it, so the flush is free.
- Indicator: a built in electronic filter change indicator that resets itself when a new cartridge clicks in. It counts water rather than dates, which is the honest way to count a faucet filter.
- Fit: a universal fitting for standard spouts, installed without tools. Non standard threads and pull out sprayer faucets are the usual exceptions, and the sheet doesn't list a thread size.
- Guarantee: a 30 day unconditional money back guarantee on Brita filters.
- Price band: $40 to $45 at our last check, in stock, sold and shipped by Amazon.com, buy box winner, with an order limit of 30 units. Treat that as a band and check the listing for the live figure.
- Category position: rank 2 in Faucet Mount Filters at our last check.
- Not published: a document or listing number. The sheet carries the document code set NI-66997, which identifies the sheet and not the certification, and that single gap is what the scorecard below is about.
What that adds up to at your tap: a cup of a housing on the spout, a glass filled in about six and a half seconds, three standards answering the taste question, the lead question and the pharmaceuticals question at once, and a cartridge that asks to be replaced about three times a year.
One hundred gallons is 1,600 eight ounce glasses, and it's also about 378 liters, which comes to roughly two filled bathtubs. Divide the same 100 gallons by the 4 months Brita prices against and the household in that sentence is drinking about 0.82 gallons a day. A household that drinks twice that much burns the cartridge in half the time, and the certification doesn't care which household you are.
Think of it this way
A pitcher is a container with a filter inside it. A faucet mount is a filter with a tap on the end of it. That reversal is the whole product: no filling, no waiting for gravity, and the same 100 gallons drawn one glass at a time instead of in a batch. The cost of the reversal is that you cannot take the water into the next room.
Brita Faucet Mount Score: 6 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 spreadsheet, not a lab, and the scorecard below is the published scoring rules 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. 1 line of the 7 sits at zero here, and it's not about the water.
| Criterion | Points | Evidence |
|---|---|---|
| Certified removal scope | 1 point | Three standards in one WQA certification, with chlorine, particulate Class I and lead carrying published percentages |
| Certification and test transparency | 0 points | The sheet publishes the standards, the capacity, the flow rate and the pressure range, and no certificate or listing number |
| Filter life and rated capacity | 1 point | 100 gallons and 378 liters, which is the figure the certification is written against |
| Cost per gallon | 1 point | About 15 to 18 cents on Brita's own cartridge prices, at the cheap end of the class, against 13 to 15 cents for the PUR cartridge in our records |
| Flow rate and pressure drop | 1 point | 0.58 gpm and 20 to 100 psig both published, about 6.5 seconds for an 8 ounce glass |
| Install and footprint | 1 point | No tools, no plumbing, one twist on a standard spout, and no counter or cabinet space given up |
| Maintenance burden | 1 point | About 3 cartridges a year at Brita's own household volume, a twist and no soak, with an indicator that resets itself |
One line sits at zero, and it is the certificate number that nobody prints. This system publishes more about itself than anything else in the faucet aisle: the standards, the capacity in two units, the flow rate, the pressure range, the test pressure, and a percentage beside every substance. What it never publishes is a number a reader can key into a registry. NI-66997 is the code on the foot of the sheet, and it names the document rather than the certification.
The flow line is the other half of the story, and it is the reason this page moved from 5/7 to 6/7 on a closer read. 0.58 gpm was on the sheet the whole time, in a paragraph most storefronts never link.
Who the Brita Faucet Mount Fits
The question is never which filter is best. It is which filter matches your tap, your lease, and the contaminant you actually named before you started shopping. This system answers the lead, chlorine and pharmaceutical questions from the spout, on 3 standards rather than 1, and it answers the chiller question by refusing to try.
Pick your side. If the concern is lead and the constraint is a rental, this is one of the cheapest certified answers on file, and the lead removal filters in the index are the wider list.
- The renter: nothing is drilled, nothing is plumbed, and the whole system unscrews in a twist and travels to the next kitchen.
- The household with a lead service line: 99.9 percent on a 0.15 mg/L lead challenge is the number on the sheet, and a carbon block that removes lead at low pH is doing the harder of the two jobs.
- The pitcher hater: no filling, no fridge shelf sacrificed, and no waiting for gravity. A glass takes about 6.5 seconds instead of about 74.
- The small kitchen or the bathroom sink: the footprint is a cup on the end of the spout, which is why Brita sells it for both.
- The household worried about pharmaceuticals: Standard 401 is the emerging compounds list, and this is one of the few faucet filters across the class that carries it.
- The low pressure household: the working range starts at 20 psig, so a weak line is inside the specification rather than outside it.
This Is Not Your Faucet Mount If
- You need PFAS specifically. Standard 401 isn't the PFAS standard, and this sheet doesn't name PFOA or PFOS anywhere. A filter that names those two compounds is a different shopping list.
- You want a published micron rating. The sheet records particulate Class I 0.5 to 1.0 micron as a claim, and a single micron figure for the media is not on it.
- You want chilled water. A faucet filter passes water at whatever temperature your pipes are.
- You want zero maintenance. Three or four cartridge changes a year is the lightest rhythm in the aisle and it is not zero.
- Your faucet is a pull out sprayer. That's the fit failure that returns more of these than any other, and the product page does not list a thread size.
The way I see it
Living with this filter is the rhythm of a toothbrush head rather than a smoke alarm. 3 cartridges a year, no soaking, no tank to scrub, and an indicator that resets when the new one clicks in. The maintenance is a twist every 4 months, and the interesting question is never whether you will remember it, because you won't have to.
Brita Faucet Mount Pros and Cons
What You Get
- Three standards on one certification: 42 for taste and odor, 53 for lead and the health list, 401 for emerging compounds. Most of this aisle carries 42 and 53 at best.
- A published flow rate: 0.58 gpm, 6.5 seconds a glass, and it is the fastest published rate in our faucet records.
- A published pressure range: 20 to 100 psig, which matters in an old house and matters more in a top floor flat.
- Near the bottom of the aisle on running cost: about 15 cents a gallon on Brita's own two pack, against 13 to 15 cents for the PUR cartridge and about 105 cents for the ZeroWater pitcher cartridge on file.
- No counter space and no cabinet space: the whole system lives on the spout, which is the one place a small kitchen has spare.
- An indicator that resets itself: the change reminder is mechanical rather than a habit you have to keep.
What It Costs You
- No listing number: the sheet names the standards, the capacity, the flow and the pressures, and never a listing a reader can look up.
- Three or four cartridges a year: the lightest rhythm in the aisle, and still a rhythm, at roughly $45 to $64 a year depending on how much you drink.
- No PFAS claim: 401 is emerging compounds, not PFOA and PFOS, and neither compound is named on the sheet.
- A 3 gallon flush: the first cartridge wants 5 minutes of water through it before the first glass, and Brita is honest that the 100 gallons starts after that.
- Proprietary cartridges: the FR-200 is the only cartridge that fits, so the fixture locks you into one supply line for as long as you keep it.
- Fit is a thread, not a guarantee: pull out sprayers and non standard spouts are the returns, and the product page won't tell you your thread size.
Brita Faucet Mount Cost Per Gallon: About Fifteen Cents
The upfront price is the least useful number on the page, and this is the aisle where that bites hardest. I have run the arithmetic across every faucet filter in the index, and this one sits at the cheap end of the class while carrying the widest certification. The consumable decides that, which is why the index keeps its own replacement cartridge comparisons.
- The system: a $40 to $45 band at our last check, with one cartridge in the box. brita.com sells the faucet system it carries today in the $30 to $35 band, which is the cheaper route to the same filter.
- The cartridge: Brita's own store prices the FR-200 at $17 to $19 singly and $28 to $32 for two, so the two pack is about $15 per cartridge. There is no FR-200 record in our catalog, so the band comes from the manufacturer's store and the page says so.
- Per gallon: about $15 divided by the certified 100 gallons is about 15 cents, and the single cartridge basis is about 18 cents. That's the number the listing doesn't show you.
- The same math on a Brita pitcher cartridge: about $5 per cartridge in our three pack record at a 40 gallon rating, which is about 13 cents per gallon. Bought in packs, the jug and the spout cost about the same per gallon, which is not what the packaging suggests.
- And on the PUR PFM350V in the same aisle: the cartridge band on file works out at about 13 to 15 cents per gallon, a whisker cheaper than this one. That is why this page does not call the Brita the cheapest gallon in the faucet aisle.
- And on the ZeroWater pitcher: about $15 to $18 a cartridge at 15 gallons, which is 100 to 120 cents per gallon, or roughly seven times this faucet mount.
- The annual reality: a household drinking a gallon a day wants 365 gallons, which is 4 cartridges at this rating, and about $56 to $64 a year at the two pack price. At the 0.82 gallons a day Brita's four month figure implies, it is 3 cartridges and about $45.
Here is the part the price tag hides: the system costs about what a month of its own cartridges costs, and the cartridge is where the next four years go. That is the whole argument for reading capacity instead of packaging.
The honest comparison is not the jug, it is the bottle. A dollar and a half at the counter, once a day, is about $550 a year, and it buys water with no certification on the label at all.
Think of it this way
100 gallons is 1,600 eight ounce glasses, and at a dollar fifty for a 16.9 ounce bottle that same water costs roughly $1,100 at the counter. The cartridge that draws it costs about $15. One cartridge repays the whole fixture, which is a sentence no pitcher in the index can write.
The two pack is where the running cost lives, and the manufacturer's own store is the only place that prices it.
Brita Faucet Mount Filter vs the Field
Every row below is a faucet filter from our own index, with certifications, capacity and flow taken from our records and manufacturer documentation. Nothing here is a manufacturer comparison chart, and the upfront figures are bands, not live prices.
| Faucet filter | Certified | Rated life | Flow | Upfront band |
|---|---|---|---|---|
| Brita Faucet Mount | NSF 42, 53, 401 | 100 gal | 0.58 gpm | $40 to $45 |
| PUR PFM350V | NSF 42, 53 | 100 gal | 0.52 gpm | $30 to $35 |
| Waterdrop FC-01 | NSF certified, no standard named in our record | 320 gal | not published | $17 to $21 |
| Culligan CULFMWH | NSF 42, 53 | 200 gal | not published | $28 to $32 |
| WINGSOL WS-FM002 | NSF 42, 53 | 350 gal | not published | $30 to $35 |
The certification column is where the aisle separates. Two of the five carry 42 and 53 with no 401, one carries 42 and 53 with a certification explainer worth reading beside it, and one carries a PFAS claim in its listing title against a record that certifies standards 42 and 53, which is not where PFAS lives. Read the standard, not the adjective.
The flow column is thinner than the aisle admits: three of these five publish no rate at all, so a buyer comparing them is comparing marketing rather than water. Brita publishes 0.58 gpm, PUR publishes 0.52, and everyone else in this table is silent.
One oddity worth knowing before you buy: the same filter is sold in two Amazon kits, and the cheaper kit ships with more cartridges. The white system in this review sits in the $40 to $45 band with one cartridge, while the chrome kit in our records sits in the $32 to $37 band with two. Same system, same FR-200 cartridge, different box.
The chrome kit bundles two FR-200 cartridges and sat at a lower band than the white one at our last check.
Brita Faucet Mount FAQ
- Does the Brita faucet mount remove lead?
- Yes, and it is written down. The performance data sheet records lead at 99.9 percent on both pH 6.5 and pH 8.5, against a 0.15 mg/L challenge and a 0.005 mg/L product water limit, inside a WQA certification that covers 42 and 53 and adds the 401 list. What the sheet does not publish is a certificate or listing number, which is the one line the scorecard leaves at zero.
- How often do you change the filter?
- Every 100 gallons, which Brita frames as up to 4 months for most households, or about 0.82 gallons a day. At a gallon a day that is 4 cartridges a year instead of 3, and hard water shortens it further. Trust the gallon figure, because the calendar is an assumption about how much you drink.
- How fast does it filter?
- The sheet publishes a service flow of 0.58 gpm, which is about 74 ounces a minute, so an 8 ounce glass takes roughly 6 and a half seconds. It is the fastest published rate in our faucet records, against PUR's 0.52 gpm and a ZeroWater pitcher's 6.5 ounces a minute.
- Does it remove PFAS?
- It carries NSF/ANSI 401, which covers emerging compounds such as certain pharmaceuticals and pesticides, and 401 is not the PFAS standard. Neither PFOA nor PFOS is named anywhere on this sheet. If those two compounds are the reason you are shopping, look for a filter that names them rather than one that carries the word forever.
- Will it fit my faucet?
- Brita specifies a universal fit for standard spouts with a tool free install, and the system works between 20 and 100 psig. Pull the aerator off your spout and look at the thread before you order, because non standard threads and pull out sprayer faucets are the usual exceptions and the product page does not list a thread size.
Brita Faucet Mount: Where It Lands
The Brita faucet mount earns 6/7, and the single line at zero is a missing number rather than a missing capability. It carries a WQA certification that covers 42 and 53 and adds the 401 list, publishes 0.58 gpm and a 20 to 100 psig working range, rates the cartridge at 100 gallons, and works out at about 15 cents per gallon.
The one thing it won't do is give you a certificate number to look up, which is the same price PUR pays for the strongest data sheet in the project. One line lost to paperwork, and six earned on the water, the flow and the price.
If lead is the reason you are reading, this is one of the cheapest certified routes in our records and the under sink systems are the longer lived ones. If PFAS is the reason, this is the wrong page and the wrong standard.
Bottom of the faucet aisle on running cost, widest certification in it, and one blank space on the label.
Where It Lands: Three Standards and One Twist
Lead at 99.9 percent inside a WQA certification covering three standards, a published 0.58 gpm, 100 gallons a cartridge and about 15 cents a gallon. If a standard spout and a rental are your constraints, this is one of the cheapest defensible answers we carry.
Brita Faucet Mount Lexicon: Every Standard in This Review
- NSF/ANSI 42
- The aesthetic effects standard, covering chlorine, taste and odor and particulate reduction. The sheet records this system at 99.0 percent for chlorine and 99.9 percent for particulate Class I.
- NSF/ANSI 53
- The health effects standard, where lead lives alongside chromium, mercury and, since PFOA and PFOS were added, the two most studied PFAS compounds. This sheet records lead at the 99.9 percent mark and does not name either PFAS compound.
- NSF/ANSI 401
- Covers emerging compounds, including certain pharmaceuticals, pesticides and flame retardants. It is not the PFAS standard, and marketing copy blurs the two constantly.
- NSF P473
- The protocol for PFOA and PFOS reduction specifically. A filter can carry 42, 53 and 401 and still carry nothing here.
- WQA
- The Water Quality Association, one of the three certifying bodies this project checks for. A certification by WQA names the standard and the model, and its listing directory answers by company and product.
- Gallons per minute (gpm)
- The rated flow of the system at a stated pressure. This one publishes 0.58 gpm at 60 psig, which converts to about 74 ounces a minute and about 6.5 seconds for an eight ounce glass.
- psig
- Pounds per square inch gauge, the pressure unit on the data sheet. This system is specified from 20 to 100 psig, which is the range a household line actually lives in.
- Rated capacity
- The volume a cartridge filters before performance is no longer certified, in gallons. This one is 100, or 378 liters, and it is the divisor in every cost figure on this page.
