Key Takeaways
- Under-sink systems with dedicated faucets (like Waterdrop 10UB) deliver higher flow rates and longer filter life than faucet-mount models, but require more installation work and counter space.
- Faucet-mount filters (PUR, Brita) are the easiest to install and swap between sinks, but they reduce water pressure and need frequent filter changes—typically every 100 gallons.
- Lead-free construction is a major differentiator: stainless steel and lead-free brass models (ESOW, KRAUS, FORIOUS) are safer for drinking water than cheaper plastic or chrome-plated options.
- 2-in-1 faucets (KRAUS Bolden, FORIOUS) save space and look seamless, but they cost more and make filter replacement harder since the filter is hidden under the sink.
- Filter certification matters more than brand: look for NSF/ANSI 42 and 53 certifications to verify contaminant reduction claims, especially for lead and chlorine.
- For renters or temporary setups, faucet-mount filters are the only practical choice; for homeowners, under-sink dedicated faucets are the better long-term investment.

More Details on Our Top Picks
ANGEL CF30 Faucet Water Filter
The ANGEL CF30 stands out among faucet-mounted options for buyers who want more stated filter capacity between replacements: its cartridge is rated for up to 350 gallons, compared with the Brita Elite Chrome’s 100 gallons per filter. Its 8-stage, 5 μm system is described as reducing chlorine, lead, odors, and rust while preserving minerals, and a switch lets you use filtered or regular tap water. The included adapters broaden its fit on standard faucets, though the compatibility limit remains significant: it does not work with pull-out or spray-style faucets. At a maximum 0.98 gpm, it also has a lower stated flow rate than the Brita Elite Chrome. Choose the CF30 for capacity; choose Brita if its higher flow and filter-change indicator matter more.
Pros:- Rated for up to 350 gallons per filter
- Eight-stage filtration is described as reducing chlorine, lead, odors, and rust
- Switches between filtered and unfiltered tap water
- Includes multiple adapters for many standard faucets
Cons:- Does not fit pull-out or spray-style faucets
- Maximum stated flow rate is 0.98 gpm, below the Brita Elite Chrome’s 1.6 gpm
- Filter replacement is recommended about every three months
Best for: Households with a compatible standard faucet that want a faucet-mounted filter rated for more gallons between cartridge changes.
Not ideal for: Owners of pull-out or spray-style faucets, or buyers who prioritize a faster stated flow rate or a filter-change indicator.
- Installation:Faucet mount
- Filtration:8-stage activated carbon; 5 μm
- Filter life:Up to 3 months or 350 gallons
- Maximum flow rate:0.98 gpm
- Operating pressure:20–100 psi
- Temperature range:41–100 °F
- Dimensions:5.31 × 2.52 × 4.33 in
- Faucet compatibility:Most standard faucets; not pull-out or spray-style faucets
Our verdict“Choose the CF30 if your standard faucet is compatible and its higher stated capacity matters more than Brita’s faster flow.”
Brita Elite Chrome Faucet Water Filter System with 2 Filters
For a buyer who wants a ready-to-install faucet filter and a spare cartridge on hand, the Brita Elite Chrome is the clearest starter set here. It includes two carbon-block filters, a filter-change indicator, and tool-free installation on standard faucets. Brita says the filter reduces lead and more than 60 other contaminants, while its 1.6 gpm flow rate is higher than the ANGEL CF30’s stated 0.98 gpm. The tradeoff is capacity: each cartridge is rated for 100 gallons, well below the CF30’s 350-gallon claim, so frequent use may mean more replacements. Its two spray options add everyday flexibility, but the system still excludes pull-out and spray-style faucets. This is a better fit for simple setup and faster listed flow than for minimizing cartridge changes.
Pros:- Includes two carbon-block filters
- Tool-free installation on standard faucets
- Filter-change indicator helps track replacement
- Listed 1.6 gpm flow rate and two spray options
Cons:- Each filter is rated for only 100 gallons
- Does not fit pull-out or spray-style faucets
- Faucet-mounted design occupies space around the sink spout
Best for: New faucet-filter buyers with a standard faucet who want tool-free setup, a spare filter, and a replacement indicator.
Not ideal for: Owners of pull-out or spray-style faucets, or high-use households seeking a larger stated capacity per filter.
- Installation:Faucet mount; tool-free on standard faucets
- Filtration method:Carbon block
- Contaminants reduced:Lead and 60+ other contaminants
- Included filters:2
- Filter life:About 4 months or 100 gallons per filter
- Flow rate:1.6 gpm
- Spray options:2
- Faucet compatibility:Standard faucets; not pull-out or spray-style faucets
Our verdict“Pick this Brita set for straightforward setup and a spare cartridge, but choose the ANGEL CF30 if longer stated filter capacity is your priority.”
VIOMI Under-Sink Water Filter with Dedicated Faucet, 1-Year Lifespan
The VIOMI is a stronger fit for buyers who want a separate drinking-water faucet and documented filtration standards rather than a unit attached to the main tap. Its 0.5-micron composite cartridge is certified to NSF/ANSI 372, 42, and 53, and the product states that it reduces PFAS, lead, and chlorine. That makes it a more standards-focused alternative to the faucet-mounted Brita Elite Advanced, which offers on-demand filtration at the existing faucet but lists no certifications in the supplied product data. VIOMI’s cartridge is rated for up to 10,000 gallons or one year, but its 0.5 gpm flow is modest, and installation needs a cold-water connection plus compatible 1/2-inch or 3/8-inch female NPT threading. Skip it if you want a quick clamp-on setup.
Pros:- Certified to NSF/ANSI 372, 42, and 53
- Rated to reduce PFAS, lead, chlorine, taste, and odor
- Cartridge rated for up to 10,000 gallons or one year
- Includes a dedicated faucet and tool-free cartridge changes
Cons:- Requires a cold-water supply connection under the sink
- Maximum flow rate is 0.5 gpm
- Faucet connection is limited to specified thread sizes
Best for: Homeowners who can connect an under-sink system and want a dedicated drinking faucet with stated NSF/ANSI certifications.
Not ideal for: Renters or DIY-averse buyers who cannot add a cold-water connection, and anyone who needs a high-flow drinking tap.
- Installation:Under sink; cold-water supply only
- Filtration:0.5-micron composite cartridge
- Certifications:NSF/ANSI 372, 42, and 53
- Reduces:PFAS, lead, chlorine, unpleasant taste, and odor
- Filter life:Up to 12 months or 10,000 gallons
- Maximum flow rate:0.5 gpm
- Operating pressure:15–60 psi
- Included components:Installation kit and dedicated drinking faucet
Our verdict“Choose VIOMI over a faucet-mounted Brita if you can install an under-sink system and value its stated certifications and dedicated tap.”
Waterdrop 10UB Under Sink Water Filter System with Dedicated Faucet
The Waterdrop 10UB suits buyers who prefer an under-sink filter but do not want the slow dispensing listed for the VIOMI: Waterdrop specifies a 0.75 gpm system flow rate, compared with VIOMI’s 0.5 gpm. It also includes a lead-free brushed stainless steel faucet, tool-free push-to-connect fittings, and a twist-and-lock cartridge design, so routine filter changes do not call for tools. I would favor it for municipal cold water and everyday drinking or cooking; its certifications cover NSF/ANSI 42, 53, and 372. The limits are clear: it is not intended for well or hot water, and its 12-month filter life is less specific than VIOMI’s stated 10,000-gallon capacity. The system also relies on coconut-shell activated carbon, a concern for buyers avoiding that material.
Pros:- IAPMO-certified against NSF/ANSI 42, 53, and 372
- Includes a lead-free brushed stainless steel dedicated faucet
- Tool-free fittings and twist-and-lock cartridge replacement
- Listed system flow rate of 0.75 gpm
Cons:- For municipal cold water only; not suitable for well or hot water
- Listed filter life is 12 months without a gallon capacity in the supplied specs
- Uses coconut-shell activated carbon, which may not suit buyers avoiding coconut-derived materials
Best for: Households on municipal cold water that want a dedicated stainless-steel drinking faucet, tool-free filter changes, and more stated flow than VIOMI.
Not ideal for: Homes using well water or hot water at the filter, or buyers avoiding coconut-shell activated carbon.
- Installation:Under sink
- Filtration method:Multistage activated carbon
- Certifications:IAPMO certified against NSF/ANSI 42, 53, and 372
- Water source:Municipal cold water only
- System flow rate:0.75 gpm
- Outlet flow rate:1.33 gpm
- Filter life:12 months
- Faucet material:Lead-free brushed stainless steel
- Temperature range:35–100 °F
Our verdict“Choose the Waterdrop 10UB over VIOMI if you want a stainless-steel faucet and higher stated flow for municipal cold-water use.”
Brita Elite Advanced Faucet Water Filter System, White, with 1 Filter
The white Brita Elite Advanced is aimed at buyers who want faucet-mounted filtration with more control at the sink: it offers three spray options, a filter-change indicator, and tool-free installation on standard faucets. Like the Brita Elite Chrome, it is described as reducing lead and more than 60 contaminants; unlike that set, it includes one filter and lists a lower 0.5 gpm flow rate. The ANGEL CF30 offers a much larger stated cartridge capacity, while this Brita keeps the familiar on-demand format and gives users more spray choices. Its filter is rated for 100 gallons or about four months, and it will not fit pull-out or spray-style faucets, despite its own spray settings. That distinction matters: the options refer to the filter’s outlet, not compatibility with a pull-down faucet.
Pros:- Offers three spray options
- Filter-change indicator signals when replacement is due
- Tool-free installation on compatible standard faucets
- Described as reducing lead and 60+ contaminants
Cons:- Includes one filter rated for 100 gallons
- Listed flow rate is 0.5 gpm
- Does not fit pull-out or spray-style faucets
Best for: Standard-faucet users who want an on-demand filter with three selectable spray settings and a replacement indicator.
Not ideal for: Owners of pull-out or spray-style faucets, or households seeking higher flow or more capacity per cartridge.
- Installation:Tool-free faucet mount for standard faucets
- Filtration method:Advanced carbon block
- Contaminant reduction:60+ contaminants, including 99% of lead
- Included filter:1
- Filter life:About 4 months or 100 gallons
- Flow rate:0.5 gpm
- Spray options:3
- Dimensions:4.8 × 2.26 × 5.28 in
Our verdict“Choose this Brita over the Elite Chrome if three spray options matter more than the Chrome model’s higher listed flow and included spare filter.”
PUR Plus Vertical Faucet Mount Water Filtration System, Chrome
For a renter or homeowner who wants filtration without adding a separate sink faucet, the PUR Plus Vertical is the most direct fit in this group. Its faucet-mounted design installs without tools on many standard faucets, and the filter-change light helps track a cartridge rated for up to 100 gallons or three months. PUR lists reductions for lead, chlorine, microplastics, and other contaminants, with NSF and WQA certification. Unlike the KRAUS Purita, it includes its own filter, so you do not need to pair it with an under-counter system. The tradeoff is frequent cartridge replacement compared with a dedicated under-sink setup, and it will not fit pull-out or handheld faucets. Choose it for a straightforward retrofit, not for a new faucet installation.
Pros:- Certified to reduce lead and other listed contaminants
- Tool-free installation on compatible faucets
- Filter-change light signals when replacement is due
- Switches between filtered and unfiltered water
Cons:- Does not fit pull-out or handheld faucets
- Filter life is limited to up to 100 gallons or three months
Best for: Renters or homeowners with a compatible standard faucet who want tool-free installation and an included filter.
Not ideal for: People with pull-out or handheld faucets, or households seeking longer-life under-counter filtration.
- Filtration method:Activated carbon and ion exchange
- Certifications:NSF certified and WQA certified
- Filter life:Up to 3 months or 100 gallons
- Installation:Tool-free faucet mount
- Compatibility:Most standard faucets with external aerators; not pull-out or handheld faucets
- Maximum supported water TDS:350 ppm
- Dimensions:2.8 x 6.4 x 5.4 inches
- Included:Faucet mount and 1 filter
Our verdict“Pick the PUR Plus if your faucet is compatible and you want an included, easy-to-install filter rather than a separate under-counter system.”
ESOW Lead-Free Stainless Steel Drinking Water Filter Faucet, Brushed Nickel
The ESOW is a practical way to add a separate dispensing point when an under-counter filter is already part of the plan. Its SUS304 stainless steel body, single-lever control, and 360-degree swivel spout give it the feel and movement of a small dedicated faucet rather than an attachment on the main tap. Two sizes of quick connectors and adapters may simplify pairing with different filtration setups. Compared with the PUR Plus Vertical, it does not include filtration or mount onto the existing faucet; it needs a compatible filter system and a spare hole in the sink or counter. That makes installation more involved, but keeps the main faucet clear and avoids a filter housing at its outlet. Check connector fit and mounting dimensions before choosing it.
Pros:- Food-grade SUS304 stainless steel body
- Brushed nickel finish resists corrosion and tarnish
- 360-degree swivel spout with single-lever control
- Includes two sizes of quick connectors and faucet adapters
Cons:- Filtration system is not included, and connector compatibility must be checked
- Requires a compatible one-hole sink or countertop location
Best for: Homeowners with an under-counter filtration system and an open mounting hole who want a separate, swiveling drinking-water faucet.
Not ideal for: Renters or buyers without a spare one-hole mounting location, and anyone expecting a complete faucet-and-filter package.
- Material:SUS304 stainless steel
- Finish:Brushed nickel
- Installation:One-hole deck mount
- Spout rotation:360 degrees
- Handle:90-degree single lever
- Sink hole fit:0.4 to 1.96 inches
- Maximum countertop thickness:2.36 inches
- Included connectors:Two sizes of quick connectors and faucet adapters
Our verdict“Choose the ESOW when you already have compatible under-counter filtration and want a dedicated faucet with flexible spout movement.”
Kraus Bolden 2-in-1 Pull-Down Kitchen Faucet with Filtered Water Tap, Chrome (KFF-1610CH)
If you are replacing the main kitchen faucet and want filtered water at the same station, the Kraus Bolden 2-in-1 is the most integrated choice here. It combines a pull-down sprayer with a separate filtered-water tap, and independent water lines are designed to keep the two supplies apart. The three functions cover filtered water, an aerated stream, and spray, so this is more versatile for sink tasks than the dedicated cold-water taps such as the KRAUS Purita. The key limitation is that the faucet does not filter water by itself: a compatible under-counter system is required and sold separately. Its 18.75-inch overall height may also crowd low cabinets or a compact sink area. This suits a planned faucet replacement better than a simple filtration add-on.
Pros:- Combines a pull-down kitchen faucet with a separate filtered-water tap
- Independent water lines help keep filtered and regular water separate
- Offers filtered, aerated, and spray functions
- Includes pre-attached water lines and mounting hardware
Cons:- Requires a compatible under-counter filtration system, sold separately
- 18.75-inch overall height may not suit every sink or cabinet layout
Best for: Homeowners replacing a kitchen faucet who want a pull-down sprayer and a separate filtered-water outlet in one fixture.
Not ideal for: Buyers seeking a standalone filter faucet, those without an under-counter filtration system, or kitchens with limited vertical clearance.
- Faucet type:2-in-1 pull-down kitchen faucet with filtered-water tap
- Spray functions:Filtered water, aerated stream, and spray
- Flow rate:1.8 GPM faucet; up to 1.6 GPM filtered water
- Spout height:6.38 inches
- Spout reach:8.63 inches
- Mounting:Fits 1- or 3-hole sinks
- Overall dimensions:10.75 x 4.25 x 18.75 inches
- Warranty:Limited lifetime
Our verdict“Choose the Bolden 2-in-1 when you are upgrading the main faucet and want filtered water integrated without sacrificing a pull-down sprayer.”
KRAUS Purita Lead-Free Filtered Water Faucet, Spot-Free Stainless Steel (FF-100SFS)
The Purita is aimed at buyers who want a distinct, clean-looking outlet for cold filtered water rather than a faucet-mounted cartridge or a full main-faucet replacement. Its lead-free solid brass body and waterways give it a more substantial construction story than the ESOW stainless-steel option, while the spot-free stainless finish helps limit visible fingerprints and water marks. The 360-degree high-arc spout can make filling a bottle or pitcher easier to position than a fixed short outlet. Like the ESOW, it depends on a separately purchased under-counter filter; unlike the Kraus Bolden 2-in-1, it does not replace the main kitchen faucet or add a sprayer. It dispenses cold water only, so it is best viewed as a dedicated beverage tap, not an all-purpose faucet.
Pros:- Lead-free solid brass body and waterways
- Spot-free stainless finish resists fingerprints and water spots
- 360-degree high-arc spout
- Mounting hardware included
Cons:- Under-counter filtration system is sold separately
- Dispenses cold water only
Best for: Homeowners with under-counter filtration who want a durable, spot-resistant dedicated faucet for cold drinking water.
Not ideal for: Buyers who need the filter included, want hot water, or are replacing their main kitchen faucet.
- Material:Lead-free solid brass
- Finish:Spot-free stainless steel
- Water type:Cold only
- Spout rotation:360 degrees
- Faucet height:12 inches
- Flow rate:1.0 GPM
- Installation:Single-hole
- Compatibility:Under-counter filtration systems, including reverse osmosis
Our verdict“Pick the Purita for a polished dedicated cold-water tap when you already have, or plan to add, compatible under-counter filtration.”
KRAUS Bolden Single-Handle Filtered Water Faucet, Spot-Free Stainless Steel
For a separate filtered-water outlet with a straightforward single-handle design, the KRAUS Bolden FF-104SFS keeps the fixture simpler than the brand’s Bolden 2-in-1 main faucet. Its brass construction, ceramic cartridge, and 360-degree swiveling gooseneck suit a dedicated cold-water station, while the spot-free finish is intended to reduce upkeep from fingerprints and water marks. It connects to most under-counter filtration systems, including reverse osmosis, but the filter itself is not included. That differs from the PUR Plus Vertical, which packages filtration in a faucet-mounted unit but requires a compatible main faucet. The Bolden needs a single mounting hole and provides cold filtered water only. Product information lists two different spout-height figures, so verify clearance before buying.
Pros:- Compatible with many under-counter systems, including reverse osmosis
- 360-degree swiveling gooseneck spout
- Brass construction with ceramic cartridge
- Spot-free stainless finish is designed for easier upkeep
Cons:- Filtration system is sold separately
- Dispenses cold filtered water only
- Product information gives conflicting spout-height measurements
Best for: Homeowners adding a single-hole dedicated tap to an existing under-counter or reverse-osmosis filtration system.
Not ideal for: Buyers who need an included filter, want a pull-down main faucet, or need a confirmed spout clearance without checking the listed dimensions.
- Model:FF-104SFS
- Material:Brass
- Finish:Spot-Free Stainless Steel
- Water type:Cold filtered water
- Compatibility:Most under-counter systems, including reverse osmosis; filtration system not included
- Faucet height:12 1/8 inches
- Spout reach:6 inches
- Spout rotation:360 degrees
- Installation:Single-hole; 1-inch mounting hole diameter
Our verdict“Choose the Bolden standalone faucet for a swiveling, single-hole drinking-water tap if you already have compatible filtration and can verify spout clearance.”
Hiqufet Drinking Water Filter Faucet for Kitchen Sink, Brushed Nickel
The Hiqufet is a dedicated drinking-water faucet for buyers who already have an under-sink filter and want a separate, straightforward outlet. Its lead-free 304 stainless steel construction and included 1/4-inch and 3/8-inch adapters make it a more purpose-built match for under-sink systems than the faucet-mounted PUR PLUS Horizontal models, which attach to compatible standard faucets instead. The 360° swivel spout and 9.4-inch reach give room to fill bottles and pitchers, while the ceramic cartridge and dual seals are intended to limit leaks. The tradeoff is fit: this faucet requires a single-hole deck mount, so it may not suit every sink or countertop. Check your filtration system’s connection and mounting layout before choosing it; it is a faucet, not a filter.
Pros:- Lead-free 304 stainless steel construction
- Includes adapters for 1/4-inch and 3/8-inch filtration connections
- 360° swivel spout with 9.4-inch reach
- Ceramic cartridge and dual-seal design
Cons:- Does not include a filtration system
- Single-hole mounting limits compatibility with some sinks
- Connection size and filter-system compatibility need checking before installation
Best for: Homeowners with an existing under-sink RO or filtration system who want a separate brushed-nickel drinking-water faucet.
Not ideal for: Renters or buyers without a compatible under-sink filter, and anyone whose sink cannot accept a single-hole deck-mounted faucet.
- Material:304 stainless steel
- Finish:Brushed nickel
- Mounting:Deck mount, single hole
- Handle:Single lever
- Spout height:7.5 inches
- Spout reach:9.4 inches
- Flow rate:1.8 gpm
- Filter compatibility:Under-sink RO and filtration systems; 1/4-inch and 3/8-inch adapters included
Our verdict“Choose the Hiqufet if you have an under-sink filter and want a separate stainless-steel faucet, provided your sink supports its single-hole mount.”
PUR PLUS Horizontal Faucet Mount Water Filtration System, Chrome
This PUR PLUS model suits buyers who want a faucet-mounted filter with specified contaminant-reduction claims, including lead, rather than a separate drinking-water faucet for an under-sink system. Its 3-in-1 filtration is certified to reduce 70 chemical and physical substances, and the included filter is rated for up to 100 gallons or three months. That gives it a more explicit filtration profile than the Hiqufet faucet, which only provides an outlet and depends on a separate filter. Tool-free installation and an on/off lever keep everyday use simple, while the change light helps track replacement. The limitation is faucet fit: it will not work with pull-out faucets or internal aerators, and its stated filtration does not cover microbes. Check your faucet aerator before buying.
Pros:- 3-in-1 filtration certified to reduce lead and 70 chemical and physical substances
- Tool-free installation on compatible faucets
- On/off lever allows switching between filtered and unfiltered water
- Filter-change light and included filter
Cons:- Does not fit pull-out faucets or faucets with internal aerators
- Filter replacement is due at up to 100 gallons or three months
- Does not filter microbes
Best for: Households with a standard faucet and visible external aerator seeking a faucet-mounted filter with stated lead and other contaminant reduction.
Not ideal for: People with pull-out or internal-aerator faucets, or buyers seeking microbial filtration or an under-sink dedicated faucet.
- Filtration:3-in-1; certified to reduce 70 chemical and physical substances, including lead
- Purification method:Ion exchange
- Filter life:Up to 100 gallons or 3 months
- Installation:Tool-free
- Compatibility:Most standard faucets with visible external aerators; excludes pull-out faucets and internal aerators
- Maximum supported TDS:500 ppm
- Material:Stainless steel
- Features:On/off lever and filter-change light
Our verdict“Pick this PUR PLUS model if your faucet has an external aerator and you want a plug-on filter with stated lead reduction, not a separate sink faucet.”
PUR Plus Faucet-Mount Water Filtration System, Lead-Reducing Filter, Gray
The gray PUR Plus is a compact route to filtered water when replacing or adding a dedicated faucet is not practical. Like the PUR PLUS Horizontal Chrome model, it mounts directly to a compatible standard faucet and uses a 3-in-1 filter with ion exchange; the listed certifications cover lead, microplastics, chlorine, and other substances. Its 6.4-inch length makes its footprint easy to gauge, while the filter-change indicator removes some guesswork about upkeep. Compared with the Hiqufet, this option includes the filtration hardware but does not create a separate outlet for an under-sink system. That convenience comes with a strict fit caveat: it is not for pull-out or handheld faucets. The plastic body and recurring filter changes may also matter to buyers seeking a metal fixture or longer maintenance intervals.
Pros:- WQA- and NSF-certified reduction claims for lead, microplastics, chlorine, and other substances
- Tool-free faucet installation
- Filter-change light signals when replacement is due
- Compact 6.4-inch length
Cons:- Not compatible with pull-out or handheld faucets
- Plastic construction rather than stainless steel
- Filter lasts up to 100 gallons or three months
Best for: Apartment dwellers and homeowners with compatible standard faucets who want a compact, tool-free filter with stated lead and microplastics reduction.
Not ideal for: Owners of pull-out or handheld faucets, or buyers who prefer a metal dedicated faucet connected to an under-sink filtration system.
- Filtration method:3-in-1 filtration with ion exchange
- Certifications:WQA certified for lead reduction; NSF certified for microplastics, chlorine, and other substances
- Filter life:Up to 3 months or 100 gallons
- Installation:Faucet mount; no tools required
- Compatibility:Most standard faucets; not for pull-out or handheld faucets
- Dimensions:6.4 × 2.8 × 5.4 inches
- Material:Plastic
- Maximum supported TDS:500 ppm
Our verdict“Choose this compact PUR Plus if your faucet is compatible and you want built-in faucet-mount filtration without installing a separate drinking-water tap.”
FORIOUS 2-in-1 Pull-Down Kitchen Faucet with RO Water Faucet, Brushed Nickel
Unlike the Hiqufet, which adds only a dedicated filtered-water faucet, the FORIOUS replaces the main kitchen faucet and includes a separate outlet for an existing under-counter RO or filtration system. That combined layout is useful when you want filtered water without adding a second fixture to the sink deck. The main tap brings three spray modes, an 18-inch retractable hose, and a 360° swivel spout, so it also handles ordinary rinsing and sink work. Its lead-free SUS 304 stainless steel construction and ceramic cartridges round out the fixture. The central tradeoff is that the filtration system is not included; buyers need a compatible under-counter unit and must account for the larger faucet replacement project. Choose the Hiqufet instead if your main faucet is staying in place.
Pros:- Combines a pull-down kitchen faucet with a separate filtered-water outlet
- Three spray modes: stream, spray, and pause
- 18-inch retractable hose and 360° swivel spout
- Lead-free SUS 304 stainless steel with ceramic cartridges
Cons:- Filtration system is not included
- Requires an under-counter system with compatible connections
- Replacing the main faucet is a broader installation than adding a dedicated faucet
Best for: Kitchen renovators who want to replace their main faucet and connect an existing under-counter RO or filtration system through a separate outlet.
Not ideal for: Buyers who only need a drinking-water faucet, do not have an under-counter filter, or want to avoid replacing the main kitchen faucet.
- Model:FF0023BN-DJS
- Finish:Brushed nickel
- Material:Lead-free SUS 304 stainless steel
- Mounting:Deck mount, single hole
- Spray modes:Stream, spray, and pause
- Hose length:18 inches
- Flow rate:1.8 gpm maximum at 80 psi
- Filtration compatibility:Most under-counter RO and filtration systems; filtration system not included
Our verdict“Choose the FORIOUS when you want one main faucet with a separate filtered-water outlet and already have a compatible under-counter system.”
PUR Plus Horizontal Faucet Mount Water Filtration System
This PUR Plus horizontal unit is another faucet-mounted option for homes with compatible external-aerator faucets, but its standout specification is a maximum supported TDS of 1000 ppm, compared with 500 ppm for the PUR PLUS Chrome and gray PUR Plus models in this lineup. That distinction may suit buyers whose source water tests higher on total dissolved solids, though TDS support is not a measure of every contaminant or a promise that the filter removes them all. Its 3-in-1 ion-exchange filtration, on/off lever, and change light make routine use familiar, and installation is tool-free. As with the other PUR faucet mounts, it cannot serve pull-out faucets or internal aerators. Unlike the Hiqufet or FORIOUS, it attaches to the existing tap rather than providing a separate outlet for an under-sink system.
Pros:- Supports water with TDS levels up to 1000 ppm
- 3-in-1 ion-exchange filtration with stated lead and chemical and physical substance reduction
- Tool-free installation on compatible faucets
- On/off lever and filter-change light
Cons:- Does not fit pull-out faucets or faucets with internal aerators
- Filter lasts up to 100 gallons or three months
- Plastic construction may not suit buyers seeking a metal fixture
Best for: Households with a compatible external-aerator faucet that want faucet-mounted filtration and need support for source water up to 1000 ppm TDS.
Not ideal for: Owners of pull-out or internal-aerator faucets, or buyers who want a dedicated filtered-water faucet connected to an under-sink system.
- Filtration method:Ion exchange
- Filtration:3-in-1; reduces lead and other chemical and physical substances, including chlorine
- Filter life:Up to 100 gallons or 3 months
- Faucet compatibility:Most faucets with visible external aerators; excludes pull-out faucets and internal aerators
- Installation:Tool-free
- Dimensions:6.75 × 2.88 × 5.25 inches
- Weight:11.2 ounces
- Maximum supported TDS:1000 ppm
- Features:On/off lever and filter-change light
Our verdict“Choose this PUR Plus if your faucet has an external aerator and the higher 1000 ppm TDS support fits your water profile; otherwise, compare its fit and filter life with the other PUR mounts.”
