  • ★★★★★

    “We ran tap water through a dozen faucet filters. Nouriven was the one that actually changed how the water tasted, the chlorine ‘pool’ note was simply gone.”

  • ★★★★★

    “The real test is whether you stop buying bottled water. Two weeks with the Nouriven on the kitchen tap, and the case of plastic bottles by the door never got replaced.”

  • ★★★★★

    “Most faucet filters are twenty dollars of plastic that cracks at the thread. Nouriven’s 304 stainless-steel body feels like it belongs on the sink and it wipes clean with a cloth.”

  • ★★★★★

    “We tested filtered-water taste on every unit we could find. In our test, Nouriven removed 99.6% of the chlorine and it was the only one that fit every faucet we tried.”

A used Nouriven cartridge after 30 days on a kitchen tap next to a new one

Everything Brown Here Was Headed for Your Glass.

Day 1, the cartridge is clean. Day 30, after one month on an ordinary kitchen tap, it looks like this.

That's sand, rust and grit from water that looked clear in the glass, now stuck in the filter instead of in you.

Made by Nouriven, the shower filter brand 200,000+ customers already use.

Four Kinds of Carbon, One Steel Shell

Our 7-Lock™ Filtration: water comes in at the top and has to pass all 7 layers before it reaches your glass.

Inside every Nouriven® 7-Lock™ cartridge:

  • Stages 1-2 · Stainless steel mesh + PP cotton. They catch sand, rust and grit first, so the carbon stays free for its real job.
  • Stages 3-6 · Granular activated carbon, KDF-55, carbon fiber, activated carbon block. Four layers in a row pull out the chlorine taste and smell.
  • Stage 7 · Ceramic balls. The last stop. From here, the water runs straight into your glass.

What It Pulls Out of Your Water

  • The Pool Taste

    That pool taste is chlorine. In our 7-Lock™ Filtration, activated carbon and KDF-55 grab it before the water reaches your glass.

  • The Bleach Smell

    Smell a glass from the tap, then one from the filter. An activated carbon block and carbon fiber pull the bleach smell out.

  • Sand, Rust and Grit

    Fine steel mesh and PP cotton catch the specks you can't see. That's the brown on the day-30 cartridge.

Nouriven faucet filter in solid 304 stainless steel, mounted on a kitchen faucet

Plastic Filters Crack Right at the Thread.

Most faucet filters are $20 of plastic. Water pushes on that plastic every time you turn on the tap, and after a few months the thread gives. Then one morning, water sprays sideways across your counter.

Nouriven's body is 304 stainless steel, the same steel kitchen sinks and good pots are made of. It holds up to the pressure, wipes clean with a cloth, and screws on snug by hand.

Plastic Drips. Pitchers Make You Wait.

Plastic tap filters wear out at the thread, and pitchers take a fridge shelf and make you wait for every glass.

Nouriven gives you filtered water in seconds, from a steel body, with 90 days to decide it was worth it.

Tomorrow morning, you fill the kettle straight from the tap. No pitcher, no bottles, no pool smell. Just water you want to drink.

Where You'll Taste It First

  • Filling a coffee pot with filtered water from the Nouriven faucet filter

    Your Morning Coffee

    Chlorine hides the taste of a good cup. Brew with filtered water and you taste the coffee you paid for.

  • Rinsing strawberries and lettuce under the Nouriven faucet filter

    Rinse the Produce

    Wash your berries, grapes and lettuce in the same filtered water you drink. One flip of the lever, right at the sink.

  • Filling an ice cube tray with filtered water from the Nouriven faucet filter

    The Ice Trays

    Ice is where tap water tastes worst. Fill the trays from the filtered side and your iced tea tastes like tea.

  • Filling a pasta pot with filtered water from the Nouriven faucet filter

    Pasta, Rice and Soup

    They soak up the water they cook in. Fill the pot from the filtered side and all you taste is dinner.

  • Filling a pet water dish with filtered water from the Nouriven faucet filter

    Their Water Bowl, Too

    If you won't drink the tap water, why should they? One flip of the lever fills their bowl with the same water you drink.

  • Filling a reusable water bottle from the Nouriven faucet filter

    Your Water Bottle

    Fill it at the sink on your way out. Clean water for the car, the walk or the gym, without buying another case.

Stop Carrying Water Home

  • 1. Save your back.

    No more cases of bottled water from the store, up the steps and into the pantry. Your drinking water comes out of the faucet you already have.

  • 2. Free up the fridge.

    No pitcher taking a whole shelf, no waiting for it to drip. A full glass of filtered water in seconds, any time.

  • 3. Skip the store run.

    You already pay for the water in your pipes. Now it's water you want to drink, with no bottles piling up by the door.

Everything in the box: the steel filter, the 7-stage cartridge and the faucet adapters

Twist Off the Tip. Twist This On.

It fits 99.9% of kitchen faucets. Unscrew the little tip at the end of your faucet, pick the adapter from the box that matches, then turn the filter on by hand. No tools, no plumber, no waiting for someone to come help, even with stiff or arthritic fingers.

If your faucet needs a different adapter, we mail you the right one. And if it still doesn't fit, you get every dollar back.

90 Day Risk-Free Guarantee

  • 90-day money-back guarantee seal

    Try it on your own kitchen faucet for 90 days. If you don't love the taste of your water, simply return it for a full refund (no questions asked).

FAQ

Will it fit my faucet?

It fits 99.9% of kitchen faucets. If the tip at the end of your faucet unscrews, you're set: the adapters are in the box, and if yours needs a different one, we mail it to you or refund you in full.

What comes in the box?

The steel filter, its 7-stage cartridge and the faucet adapters. Everything you need to put it on is right there, with nothing else to buy.

Can I put it on myself?

Yes. Unscrew your faucet tip, screw on the adapter, then turn the filter on by hand. No tools, no plumber, and no one to call.

How does the lever work?

One lever, two kinds of water. Flip it one way for filtered water to drink and cook with, and the other way for regular tap water to wash the dishes, which saves your cartridge for what you drink.

What does it take out?

The chlorine taste and smell, plus sand, rust and grit. Steel mesh and PP cotton catch the specks, activated carbon and KDF-55 take out the chlorine, and ceramic is the last stop before your glass. We call it 7-Lock™ Filtration.

When do I change the cartridge, and how will I know?

Every 3 months. Your water tells you too: if the filtered stream slows down, rinse the cartridge under the tap and it flows again. A new cartridge twists in by hand in a minute.

Will my water come out slower?

The filtered side gives you a steady stream made for filling a glass, a kettle or a pot. When you want a strong flow for the dishes, flip the lever back to regular tap water.

Can I use it for ice, coffee and cooking?

Yes, that's what it's for. Fill the ice trays, the coffee pot, the kettle, the pasta pot and the pet bowl from the filtered side.

Can I take it with me if I move?

Yes. It unscrews by hand, so you put your original faucet tip back on and your faucet is just as it was. Then it goes on your new kitchen tap.

Do I have to sign up for a subscription?

No. You buy once. When you want a fresh cartridge, you order it yourself, when you want it.

Is this the same Nouriven as the shower filter?

Yes. More than 200,000 customers already use our shower filters, and this is the same company with the same 90-day promise, now for the water you drink.

What if I don't like it?

Use it for 90 days. If you don't love the taste of your water, send it back and get a full refund. Shipping is free, right to your door.
