Kitchen Faucets with a Water Filter Built In: 7 Picks Compared

A filter cartridge inside a kitchen faucet can clean 700 gallons before you swap it.

That’s the rated life of the Cobbe faucet’s filter, about 2-3 months of drinking water for a family of 4.

But many faucets sold as a kitchen faucet with a water filter built in contain no filter at all. They only add a spout for an under-sink system you buy separately.

Below are 7 picks, ranked by how much of the filtering each handles straight out of the box, with filter life, flow rate and sink fit for each.

• No filter under your sink yet? The Cobbe (#1) brings its own cartridge plus 2 spares.
• If an RO system already lives in your cabinet, the OWOFAN (#5) gives it a matching spout.
• Homes with small kids may like the HOMELODY (#4), whose LED shows how hot the water is.
• Two-handle fans get hot, cold and a drinking spout with the FORIOUS (#7).

Quick Comparison Chart

Built-In Filter or 3-Way Faucet: Which Do You Need?

A kitchen faucet with a water filter built in comes in 2 types: faucets with a filter cartridge inside the faucet (picks #1 to #4), and 2-in-1 or 3-in-1 faucets that only add a filtered spout for an under-sink filter or reverse osmosis system you buy separately (picks #5 to #7). If you have no filter under the sink today, pick the first type.

Big brands sell the second type as a pair. For example, Kraus USA’s own Facebook post pitches its Bolden 2-in-1 Water Filter Faucet with a Purita filtration combo for filtered water on demand.

Both types are point-of-use water filters, so they treat only the tap water at that one sink. That’s the drinking water and cooking water most families care about.

Here’s what each pick was judged on:

• Where the filtration happens: inside the faucet, or in an under-sink system sold separately.
• Filter life: the gallons or months each listing gives per cartridge.
• Certifications: NSF/ANSI/CAN 61, NSF 372 and lead-free claims on the listing.
• Flow and fit: gallons per minute, sink holes, hole size and deck thickness.

None of these faucets was lab tested for this guide, so every spec below comes from each product’s own Amazon listing.

1. Cobbe Kitchen Faucet with Water Filter

The Cobbe is the best pick for a kitchen with no filter yet, because the cartridge lives inside the faucet. You don’t add a tank, a separate water dispenser or a new hole in the counter.

Cobbe rates each activated carbon cartridge for 700 gallons, about 2-3 months for a family of 4. And since 3 filters ship in the box, that’s roughly 6-9 months of filters before you reorder, using Cobbe’s own estimate.

No other faucet on this list states a bigger filter capacity. The AIMADI (#3) lists 350 gallons, half as much.

The body is lead-free SUS304 stainless steel built to NSF/ANSI/CAN 61 and cUPC standards. Before you order, check that your sink hole measures 1.3-1.38 inches and your deck is no thicker than 1.5 inches.

Cobbe pitches it as a way to rely less on bottled water, and the same faucet also comes in brushed nickel if matte black doesn’t suit your kitchen.

2. FEELSO Filter Water Kitchen Faucet

The FEELSO suits you if you want filtered water with almost no setup. The filter comes already installed, so you mount the faucet, connect the hoses and pour a glass.

Its filter pairs activated carbon fiber with ultrafiltration, a very fine membrane that traps small particles. FEELSO’s listing says to replace the filter every 2 months, depending on your water quality and use.

The main spout runs at 1.6 GPM, which the seller says uses 27% less water. That’s the lowest flow stated on this list, so it fits homes that want to save water.

Compared with the Cobbe (#1), you get no gallon rating and no spare filters in the box. So the Cobbe makes running costs easier to plan, while the FEELSO wins on simple setup and a 2-year free replacement policy.

3. AIMADI Kitchen Faucet with Water Filter

The AIMADI is the pick for big, deep sinks. Its spring coil high-arc spout reaches over tall pots, and the main stream runs at 1.8 GPM.

The filtered outlet is a different story. AIMADI lists it at 0.5 GPM with 350 gallons per filter, or about 3 months.

What does 0.5 GPM mean for you? Filling a 1-gallon pot with filtered water takes about 2 minutes.

The listing is also upfront that this filter does not reduce TDS, the total dissolved solids such as minerals. If TDS is your worry, you’ll need a countertop reverse osmosis filter or an under-sink RO system instead.

Compared with the Cobbe (#1), you get half the rated filter life but a taller, more flexible spout.

4. HOMELODY LED Filter Water Kitchen Faucet

The HOMELODY is the pick for homes with kids. Its LED changes from blue to green to red as the water heats, so you can see hot water before anyone touches it.

The display runs on the water flow itself, so there are no batteries to replace. Under the spout, the filter uses the same carbon fiber and ultrafiltration setup as the FEELSO (#2).

HOMELODY lists the faucet as CEC listed, DOE certified and NSF 61/372 and lead-free, with a 3-year warranty. That’s the longest warranty stated on this list.

The downside? The listing gives no filter capacity or swap interval, so plan on checking taste and flow every couple of months.

5. OWOFAN 2-in-1 Kitchen Faucet with Filtered Water Spout

The OWOFAN is the pick if a reverse osmosis or carbon system already sits under your sink. It swaps your separate RO tap for one faucet with 2 outlets, so you free up a hole in the counter.

Unlike picks #1 to #4, there’s no filtration inside the faucet. OWOFAN’s listing says its spout works with most under-sink RO and inline carbon systems, sold separately.

If you’re starting from scratch, budget time for installing an under-sink filter as well as the faucet.

The faucet itself is certified to NSF/ANSI/CAN 61 and lead-free, and it runs at 1.8 GPM at up to 80 PSI. Note that the filtered spout is a non-air-gap tap, so confirm your RO system works with that type before you buy.

6. GIMILI 3-in-1 Filter Kitchen Faucet

The GIMILI suits you if you like the open-coil commercial look and plan to pair it with your own under-sink filter. Hot water, cold water and filtered water all come from one faucet.

GIMILI’s listing is clear that it does not include a water purification system. A simple inline water filter under the sink is one way to feed the pure-water outlet.

Here’s how the sizes work out: 20 inches tall, an 8.67-inch reach and a 5.9-inch spout height. The 23.6-inch hoses use 3/8-inch compression threads, so check them against your supply valves.

Compared with the OWOFAN (#5), the GIMILI gives you the same idea in a commercial style, with a forged body the listing says resists corrosion and rust. But its spray must be held down by hand.

7. FORIOUS 2-in-1 Kitchen Faucet with Drinking Water Spout

The FORIOUS is the pick if you want two handles instead of one lever. It combines a pull-down kitchen faucet and a drinking water spout in a black finish.

Like the OWOFAN (#5), it needs an under-counter system: the listing calls it a non-air-gap filter faucet, systems not included.

Measure before you order. The faucet stands 19.69 inches tall, so check the clearance under any shelf or cabinet above your sink.

How Often Do You Replace a Faucet Filter?

A kitchen faucet with a built-in water filter needs a new cartridge about every 2-3 months, based on these listings: FEELSO says every 2 months, Cobbe rates 700 gallons (2-3 months for a family of 4) and AIMADI rates 350 gallons or 3 months. Heavy use or poor water quality shortens that.

Here’s a simple way to stay on schedule:

1. Write the install date on the faucet’s box or a piece of tape under the sink.
2. Set a phone reminder for 8 weeks out, the shortest interval on this list.
3. Swap sooner if the filtered flow slows or the chlorine taste comes back.

So if you’d rather change filters once or twice a year, a larger multi-stage water filter under the sink may suit you better than a cartridge in the faucet.

Will a Filtered Kitchen Faucet Fit Your Sink?

Most kitchen faucets with a water filter built in fit a 1-hole sink and cover a 3-hole sink with an included deck plate. The Cobbe needs a 1.3-1.38 inch hole and a deck no thicker than 1.5 inches.

Check 3 things before you buy:

• Holes: count the holes in your sink or counter, and use the deck plate if you have 3.
• Height: measure the space above the sink, since the GIMILI stands 20 inches tall.
• Under-sink room: picks #5 to #7 need space for a filter or RO tank in the cabinet.

If you’d rather keep the faucet you have, there are filters that pair with pull-out faucets without replacing anything on the counter.
