Reading up on Domino's shopping guides is like having your own personal product concierge. We do the tedious part—deep-dive research, hands-on testing, and tapping experts for advice—so all you have to do is hit "add to cart." That's why we call them Simply the Best.

Getting filtered water in your kitchen these days doesn't mean attaching a clunky piece to your sink or lugging out a huge pitcher from your fridge. Faucet water filters are essentially their own mini sink faucet that provide you with decontaminated water while blending in seamlessly to your current kitchen aesthetic.

"Pretty much in all our remodels and new builds they want separate water filters," says interior designer Nina Jizhar. "Recently I’ve seen them in a black matte finish, so they’re looking very modern and very sleek."

Not only do the best faucet water filters unobtrusively fit in next to your current faucet, but they ensure your family clean drinking and cooking water by using an extensive filtration process. We tapped the experts, to see what to expect from them, and designers on what to seek on the outside.

Size: 9.5 inches tall | Material: Zinc | Filtration tech: Reverse osmosis

What we like:

Worth noting:

Why we chose it: Available in six gorgeous finishes, this sleek mini faucet hooks up to your current under-the-sink filter.

If you’re looking for a sleek hookup to your current reverse osmosis system, this contemporary faucet from Delta is a winner. It comes in a wide array of finishes, including the black matte that Jizhar says is trending, so you can best match your current kitchen design. It only measures 9.5 inches tall and has a 360-degree swivel, meaning someone can maneuver this mini faucet to fill up their cup while someone else is washing the dishes. Best of all, it comes with a lifetime warranty and also makes for a good option if you want to spruce up your minibar sink.

Size: 15.71 inches tall | Material: Stainless steel | Filtration tech: Reverse osmosis

What we like:

Worth noting:

Why we chose it: In gleaming stainless steel, this affordable option makes for a simple filter addition.

You may need to purchase a separate OR filtration system, but the hookup for the Waterdrop couldn't be easier. It connects to 1/4-inch and 3/8-inch PE tubing, and the spot rotates 360 degrees for easy water fill-up. It's also available in a sleek matte black, and the material is rust resistant and has a triple O-ring seal, so water won't seep through the bottom. As one of the more affordable options on the list, it also has an impressive max flow rate of 1.63 GPM.

Size: 11 inches tall | Material: Brushed gold | Filtration tech: Reverse osmosis

What we like:

Worth noting:

Why we chose it: Sleek gold will wow anyone filling up a cool glass of filtered water.

True to Moen's kitchen products, this shimmering faucet makes getting a cup of cold water look stylish. Available in four other finishes, we’re partial to the luxurious brushed gold that complements a high-arc rotating spout. Plus if you have other Moen modern kitchen and bar faucets, this option will match perfectly. Note that for filtered water, you’ll need an existing reverse osmosis system, but thankfully hooking it up doesn't require professional help.

Size: 11.25 inches tall | Material: Brass | Filtration tech: Reverse osmosis

What we like:

Worth noting:

Why we chose it: This bar faucet is a standout for modern kitchens.

This matte white finish is a little more toned down compared to shiny stainless steel. The rounded square edges make for an eye-catching look that matches seamlessly with other Jason Wu for Brizo kitchen collection products for a fully modern vibe. Like other faucet filters, this one must be hooked up to a separate reverse osmosis filter—but that isn't too much of a challenge.

Size: 8 inches tall | Material: Zinc | Filtration tech: Reverse osmosis

What we like:

Worth noting:

Why we chose it: A shorter faucet that won't overpower your kitchen sink.

Available in six different relaxed finishes, the Wellspring beverage faucet adds a traditional look that matches other Kohler products. At just 8 inches tall, it's one of the shorter options on this list, meaning it won't jut out too much. The gooseneck swing spout makes filling large pitchers a breeze, and the ceramic valve gives you a good flow rate for filling up a pot for pasta. However, it needs an under-counter water filter or chiller for quick access to clean drinking water.

Size: 6 9/16 inches tall | Material: Brass | Filtration tech: Reverse osmosis

What we like:

Worth noting:

Why we chose it: This low-profile filter faucet offers both cold and hot water on tap.

This water faucet may be mistaken for a soap dispenser, but the unobtrusive industrial design is a winner in our books. Unlike most other faucet water filters, this one has a cold- and hot-water option bringing you filtered cold water between 39.2 and 50 degrees Fahrenheit, and 190-degree Fahrenheit hot water to brew tea on tap. Its small size does make its flow rate a little lower, but it shouldn't be that big a deal if you’re just filling up a cup.

Because most faucet water filters need to be hooked up to a reverse osmosis system (more on that later), design is at the forefront with these products. Ideally you’ll be able to find one that matches your current faucet or one that complements it well. We stuck to options that fit a wide variety of design styles and budgets. We also tapped some industry leaders to determine how these filtration systems work and what they’re seeing being added to kitchens these days.

Most faucet water filters are available as part of a kitchen collection, which means you can match it perfectly to your current sink situation. However, if you have an older faucet or one that is a stand-alone, you can likely find something close to your finish. Common finishes Jizhar is seeing include black, nickel, and matte black.

But Jizhar doesn't recommend mixing things up too much from your current option. If anything, you can place your sink faucet so that it makes room for the faucet water filter. "When they’re side by side, you want to get one that is similar-looking," she says. "If your kitchen has more of a design, I wouldn't recommend straying too far from that."

No one wants it to take more than a minute for a faucet to fill up their glass. That's why flow rate is important. While faucet water filters may be a little slower than under-the-sink water filters, generally anything over a gallon per minute—or 1 GPM—is speedy enough so you won't notice anything sluggish, according to Derek Mellencamp, general manager at Aquasana.

This rate is dependent on two things: the size of your faucet and the capability of your filter. Smaller or thinner faucets will take longer for water to flow through, and the filtration system itself will take additional time to filter the actual water before clean water exits through the sink.

Most faucet water filters come with just the stylish hardware and not the actual filtration system. However, they are compatible with a reverse osmosis system. These systems are essentially "a membrane that you force water through under pressure so that it rejects chemicals that are larger than a water molecule," according to Mellencamp.

An RO filter takes dissolved solids and toxins out of the water as well as chlorine, fluoride, heavy metals, bacteria, and pesticides. However, it does create some wastewater through this process, which typically goes back down your drain; this makes the install a bit more complex.

To install your faucet water filter, you need to attach both your faucet and your filtration system separately. ​​For those more complicated systems, such as an RO filter, it's recommended to hire a professional to ensure you’re set up properly. If you need to drill any holes into your countertop to attach your new mini faucet, it might be a good idea to hire a contractor to get the measurements right.

Typically, care ensures that your faucet is still properly sealed and that the filter in the reverse osmosis system is replaced every six months or so, says Mellencamp. That's when the material typically deteriorates as part of the filtration process.

Unfortunately, a water filter doesn't remove everything, and depending on your filter type, can remove one thing over another. Some that remove chemicals may not effectively remove germs, and vice versa. Reverse osmosis systems might also remove minerals such as fluoride in the process.

The best way to match your filter is to shop from a kitchen collection from your brand of choice, which will have everything from handles to faucets that match in both style or colors. Otherwise, according to Jizhar, you can match your current faucet finish as closely as possible—or stick with a simple stainless steel that isn't too obtrusive.

According to Mellencamp, filters themselves should be changed every six months when they typically first wear out. But the faucet itself should last between 15 and 20 years.

Faucet water filters can be a stylish way to easily incorporate filtered water into your kitchen—without using pitchers or clunky over-the-faucet options. The Delta Contemporary Beverage Faucet offers the most common finishes and a simpler silhouette that should match most kitchens. For a more budget-friendly option, the Waterdrop Water Faucet in stainless steel is both affordable and unobtrusive. Note that both require a separate water filtration system to get clean water.
