The Best Juicer Is a Slow Juicer
Frequently Asked Questions
How We Tested and What We Tested
We put each juicer through the paces, funneling a mountain of vegetables and fruit through each device, testing especially its ability to handle both tough and fibrous veggies and softer produce such as greens and berries. We taste-test a classic green juice (apples, carrots, celery, cucumber, leafy greens) and a carrot-apple-ginger. We also compare both the yield and frothiness of the juice among different juicers, from the same recipe or the same fruit.
As of the most recent round of testing (January 2025), we also subjected each device to “torture tests” by intentionally not following instructions: loading produce in the wrong order, failing to chop ginger or pineapple, and leaving lemon in its peel, to see which devices spin fruitlessly or jam up sadly with fiber and pulp.
We test each device with a decibel meter, noting when it’s much louder or quieter than the 65 decibels one might reach during polite conversation. And we assess each device for ease of cleaning.
Some cocktails were also created, all in the name of research.
What Are the Different Types of Juicers?
Most all-purpose juicers fall into one of two types. Centrifugal juicers or masticating slow juicers that are also known as “cold press.”
A centrifugal juicer offers speed and a lot of power. In essence, it operates a bit like a blender with an added mesh screen to separate juice from pulp. A fast-rotating blade shreds fruit and produce and grinds them up against a mesh screen, often at a speed of thousands of revolutions per minute. Whatever passes through the mesh is the juice.
The power and speed mean centrifugal juicers are often whizzes at processing roots, pineapples, and other harder or dense-fibered produce that might pose difficulty for a slow-press auger. Softer fruits such as berries or leafy greens won’t do so well here, offering lower juice yields or even clogging up the mesh screens. Centrifugal juicers also tend to produce frothier juice, given the high agitation. That said, rotating quickly also makes them quick.
A masticating juicer—sometimes called a “slow” or “cold press” juicer—is both the newest trend in juicing and a much older technology. Basically, slow juicers operate on the same principle as an old-fashioned cider mill, slowly “chewing” and pressing fruit at a much lower rate, which some believe subjects fruits and vegetables to less oxidation and heat and thus preserves more of their essential character.
More verifiably, slow juicers tend to net higher juice yields and less waste than centrifugal juicers and are more effective in particular on leafy greens, soft fruits, and berries. They also add less froth and aeration to the resulting juice and produce more evenly textured results.
Masticating juicers were once loaded into a horizontal grinder and chute, which took some effort and required you to attend to juicing during the whole process. More recently, the advent of vertical masticating juicers from South Korea changed all that—with big hoppers one can load up, shrug, and depart from as the juicer does its work. The majority of juicers we’ve included in our guide, and all of our top picks, are now slow, masticating juicers.
We’ve also included a classic citrus juicer for simple orange, lemon, and lime drinks. These are quite simple devices and mostly the same as each other aside from style and ergonomics. Basically, you press a halved citrus fruit onto the ridged dome of a reamer and turn on the device. The reamer will twirl till the juice is juiced.
Masticating and centrifugal juicers can, of course, juice unpeeled citrus—and the added zest can be quite flavorful in lemon and lime juice. (Actually, this is my preference.) But to avoid such zestiness, you’d otherwise have to peel your citrus before loading into a juicing chamber. The easiest way to juice an orange will always be to halve it and press it against the ridged dome of a citrus juicer.
Are Juicers Good for Your Health?
Juicing is an easy way to add more fruit and vegetables to your diet, but it’s not a magic fix. There area few easy ways to maximize the health benefits and minimize drawbacks like blood sugar spikes.
WIRED contributing reviewer Emily Peck talked to Kylie Jane, nutritionist and founder of UK wellness brand SANA Wellness (unrelated to Korean juicer brand Sana Products), for her advice on healthy juicing. These are the five ways to ensure that juicing is a healthful addition to your life and avoid sugar overload.
- Balance fruit with vegetables: Fruits can contain a lot of sugar, so to combat this, make vegetables the base of your juices. Aim for a ratio of 80 percent vegetables to 20 percent fruits. Try spinach, kale, cucumber, celery, ginger, and beetroot. When adding fruits, go for those with a lower glycemic index like green apples, berries, and pears.
- Incorporate fiber: Juicing removes most of the fiber from fruits and vegetables, but it’s crucial for slowing down the absorption of sugar, aiding digestive health, and keeping you feeling full. Consider blending some of your juice with whole fruits or vegetables to keep some of the fiber intact. Alternatively, add a fiber supplement or incorporate some pulp in cooking or baking to ensure you’re getting enough.
- Add healthy fats: To stabilize blood sugar levels and increase satiety, incorporate sources of healthy fats into your juicing routine, such as avocado or coconut oil.
- Enhance with “superfoods”: Matcha and collagen are popular supplements that can easily be added to juices for an extra health boost. A teaspoon of matcha is rich in antioxidants and provides a gentle energy boost without the jitters of caffeine. Collagen may help with skin elasticity and hydration, as well as healthy hair, nails, and joints.
- Choose the right time to juice: Drinking juice on an empty stomach can sometimes cause blood sugar levels to spike more quickly. It’s often better to drink juice as part of a meal or after you’ve eaten some solid food, especially foods high in fiber, protein, or fats, to help slow down the absorption of sugar.
What Juicer Accessories Are Important?
Once you’ve decided what ingredients you want to put in your juicer—be it hard fruit or leafy vegetables—it will be easier to choose between a masticating “slow” juicer or a faster centrifugal design. Either way, it’s important to look for a juicer that comes with the relevant accessories you need. For tasks other than juicing—such as making nut milks and butters or ice creams and sorbets—you’ll need a juicer with the relevant food processing parts.
Also consider how much you’re willing to prep your ingredients. While there are regulations on the size of the feeding chute you can find due to safety reasons, some juicers are equipped to take a whole apple in one, which means less chopping. To make it even simpler, the most modern slow juicers, like those from Nama and Hurom, have self-feeding hoppers.
Dishwasher-safe parts are practical and save scrubbing time, but please be aware, even the easiest-cleaning juicers will take time and attention to clean. Pith, rind, pulp, and juice are sticky and messy. That’s just how it is.
A Reverse button is another useful feature to look for, especially with slow juicers. This allows you to reverse the juicing process should you overeagerly stack your juicer and ingredients gets stuck.

Tribest Slowstar AI Vertical Hopper Juicer for $600: I’m still testing the full capabilities of this brand-new device from Tribest—perhaps the most interesting new juicer of the past couple years. While the rest of the kitchen went smart, most juicers have remained resolutely analog. But this Tribest is a touchscreen device with preset spin speeds for individual vegetables and an AI-controlled function that modulates spin speed depending on the resistance of each produce item. This seems to work, making this thing an absolute beast for pitching through tough lemon peels or ginger. So far, so good! But there are compromises, including a smaller hopper size and a lower continuous operating time than my top picks. And while its screen-free hopper and feeder design is easy to clean, it’s still not as simple to clean and reassemble as the Hurom H70, and there are more parts to keep track of. And so upon initial testing, it remains just below the top-pick threshold, as I continue to suss out the device’s performance.

Kuvings AUTO10 Juicer for $730: The Kuvings AUTO10 is the original big-big-big juicer, a 3-liter hopper meant for large batches without ever having to load an extra carrot or an extra batch of spinach. The extra liter of space over the J2 will matter to some power users. The stainless steel blade and added strainers on the AUTO10 Plus upgrade are also nice touches. But this size comes at the expense of bulk and height—making this a difficult fit for most kitchen counters. While this Kuvings is a slightly higher-watt machine than the Nama J2, the versatility of the J2’s multiple hoppers and accessories, and its US-based customer service, gives the Nama a slight edge. But if you know you’re a big-batch juicer, you will not go wrong with this Kuvings.

Omega Juicers VSJ843RR for $399: WIRED contributing reviewer Emily Peck tested and recommended this juicer in previous versions of this guide, praising its excellent juice and high yield. But the device is less intuitive than the current generation of high-end juicers, leafy greens required a bit of fiddling to push through the feeder tube, and the device struggled with fibrous vegetables such as pineapple and broccoli.

Sana 707 Cold Press Juicer for $200: This is a classic horizontal juicer, the style in vogue for much of the previous century. It offers a lot of versatility, with attachments for anything from coffee to pasta. And it’s economical, as compared to hopper-style juicers. But as with other skinny-mouth feeders, you’ll find yourself hand-feeding carrots and celery and little apple wedges to make a juice batch.
Omega Time-Saving Batch Juicer for $226: WIRED had previously recommended this set-and-forget model from Omega as a budget slow juicer, despite lower performance than top picks that cost twice as much. But we’ve put it back on the testing bench after seeing some consumer feedback about durability, and for now we’re more likely to recommend fast-spinning centrifugal juicers as a budget option.
Omega Juicers Wide Mouth Cold Press Juicer JC4000 for $135: On the one hand, this Omega wide-mouth is quite economical for a slow cold-press juicer. But it’s also a lot of fiddly work to assemble it properly, it leaves a fair amount of pulp unextracted, and despite its “wide-mouth” name, requires a bit of chopping to feed fruits that aren’t carrots or celery through its vertical feeder—at least as compared to newer-model hoppers. It’ll get the job done, for not a lot of money. But you may not fall in love with it, and as a budget cold-press pick I prefer Omega’s batch model.
Gone but not forgotten: The Sana 868 wide-mouth vertical juicer ($300) is still gettable on Amazon, but it’s listed as discontinued on Sana’s site. The 868’s feeder-tube style is not in vogue at the moment, but the utility for this device comes from the low cost and the coarser screens that allow this device to be used for both juicers and smoothies. This said, if you mostly make smoothies in the morning, a blender is a whole lot easier to clean.

The base of the lamp has two slider buttons. One toggle adjusts the warmth, from cold white light all the way to red. One adjusts the intensity, from ultra-bright down to a glareless glow. Hard taps on each button skip ahead, while holding the toggle down on one side or another adjusts the light settings quite slowly—slowly enough I at first sometimes question whether it’s happening.
The maximum brightness is 1,000 lumens—the approximate intensity of a 75-watt incandescent bulb. At this brightness, the battery lasts about five hours. At a lower intensity, this can extend to as long as a dozen hours.

There’s an added feature I have come to appreciate at night, which is the red-light mode. There’s little evidence that blue light from your little smartphone is keeping you awake at night. But numerous studies do show that blue light wavelengths can affect melatonin levels and thus your body’s circadian rhythm, while red light doesn’t do this.
Red light therapy is, of course, the province of TikTok as much as science—a field where wild exaggerations live alongside legitimate uses and benefits. For every sleep study showing that red light is superior to blue light when it comes to melatonin levels, there’s another showing that red light is associated with “negative emotions” before bed.
So I can only offer my own experience, which is that Edge Light Go’s red reading light offers me a pleasant liminal space between awake time and sleepy time, one not offered by a basic nightstand lamp. It allows me to sort of bask in a darkroom space that still lets me see and read, and drift off a little easier.
If I fall asleep, the light has an automatic 25-minute shut-off, which means I won’t do what I far too often do, which is drift off while reading and then wake up, alarmed, to a room filled with bright light in the middle of the night.
Caveats and Quirks

This said, for all the virtues of portability, the Edge Light Go does not boast a base that’s heavy enough to stop the lamp from tipping over if I bend it forward from its lowest hinge. This can be an annoyance when trying to use the lamp as a reading light from a bedside table or the arm of a couch.
With reliable mobile connectivity still a major issue inside modern office buildings – particularly as energy-efficient materials block signal and user expectations remain high – connectivity infrastructure-as-a-service (IaaS) provider Freshwave has launched 5G on Omni to offer businesses “assured” indoor 5G connectivity from all the mobile network operators (MNOs).
Freshwave said that its mission is to invest expertise and capital to assure connectivity, bringing mobile operators, central and local government, and real estate providers to work together in new ways. It added that it has connected some of the biggest, most challenging wireless environments in the UK, including several central London boroughs and more than 2,000 buildings.
At launch in June 2024, the company’s Omni Network was described as a world first, offering 4G mobile connectivity indoors from all the UK mobile network operators via a combined small cell unit. It boasts more than six million square feet of real estate live or in-build.
Omni Network was previously only available on Andrew Onecell, but the solution is now multi-supplier, being available using Ericsson Radio Dot technology which is seeing use in the new 5G on Omni offer.
In another claimed first and the next stage in the evolution of the Omni Network, 5G on Omni is designed to deliver 4G/5G connectivity indoors from all the UK MNOs – EE, O2, and VodafoneThree – via the Ericsson’s Radio Dot System, extending the 5G carrier-grade mobile coverage to more spaces than ever before.
Aiming to address the aforementioned issue whereby building materials can potentially block mobile signals from reaching indoors, Freshwave said its dedicated multi-operator in-building mobile system can ensures everyone inside has the mobile connectivity they need, no matter which network they’re on.
Connecting securely to the MNOs’ networks, 5G on Omni is configured and controlled by Freshwave’s engineers via the company’s datacentre as a fully managed service. For organisations whose connectivity needs are met by 4G today, 5G on Omni provides a simple software upgrade path to 5G when required.
In addition, the company said that 5G on Omni uses up to 50% less energy than a traditional distributed antenna system (DAS), is faster and more cost effective to deploy with less cabling, and needs less space in the comms room.
Remarking upon the launch and its objectives, Simon Frumkin, Freshwave’s CEO, said: “After a world-first with Omni Network, I’m delighted we’re now able to offer our customers another first with 5G on Omni. It’s the next stage of assured indoor mobile connectivity, bringing all the operators indoors on 5G via small cells.
“Indoor connectivity is an essential productivity driver, as evidenced by our Mobile connectivity ROI index which found that the UK could gain £70bn of added value by eliminating mobile signal not-spots indoors. 5G on Omni represents an important step forward for indoor connectivity in the UK. We’re grateful to all the UK mobile operators and to our technology partner Ericsson for their collaboration in making this possible.”
Luca Orsini, head of Ericsson North Europe, added: “We’re thrilled to have collaborated with neutral host provider Freshwave to deliver 5G from all UK mobile operators on the Ericsson Radio Dot for the very first time. It highlights how shared indoor infrastructure can accelerate high-quality 5G coverage and capacity at a lower total cost of ownership than legacy solutions, ensuring organisations and users benefit from seamless connectivity regardless of their mobile provider.”
The service is also available via a pay-as-you-occupy model, which allows landlords to pay to cover shared areas in a building, while giving tenants the ability to contract directly with Freshwave to join the in-building system as and when they move in.
Freshwave claims 5G on Omni is already seeing strong demand and that it is in the process of deploying it at several other customer sites this year across sectors including financial services, luxury goods brands and a global fast moving consumer goods company. One of the early adopters of the service has been flexible office provider Workspace’s Record Hall site in central London, bringing 4G/5G mobile signal from all the MNOs to the offices and workshops there.
“Good connectivity should be something our SME customers don’t have to think about,” said Chris Boultwood, head of technology at Workspace. “With 5G on Omni from Freshwave now live at Record Hall, our customers can rely on seamless mobile coverage throughout the building, whichever network they use.”
For airlines to run critical operations on networks that are set up and run for them, removing the complexity and cost of managing connectivity themselves, air industry tech firm SITA has launched a new network solution designed to support the demands of complex airport and transport environments.
With around 2,500 customers, SITA technology supports more than 1,000 airports and more than 19,600 aircraft worldwide. The company said that it also helps more than 70 governments “strike the balance between secure borders and seamless journeys” and connects 45-50% of the industry’s data exchange to enable complex global networks to operate smoothly and reliably.
As part of the latter aim, the SITA Campus Network, powered by HPE Aruba Networking, aims to offer a managed network service covering more than 150 countries wherein SITA takes care of the design, procurement, shipping, installation, configuration and support for all devices involved. Boasting a low total cost of ownership (TCO), SITA is proposing “one of the most competitive” fully managed local area network/wireless local area network (LAN/WLAN) available in the industry.
Explaining the rationale for the launch, SITA noted that managing networks across multiple locations, devices and suppliers is complex and costly. Furthermore, it said that when networks are fragmented, performance suffers and disruptions can spread quickly.
SITA Campus Network is attributed with being able to remove this burden by delivering a fully managed network across wired and wireless environments. The campus network is claimed to combine “robust” connectivity with centralised, cloud-based management to ensure consistent, reliable performance across airport campuses and other large transport hubs.
Designed for high-density environments such as terminals, hangars and airline operations centres, the solution is said to support large volumes of users and devices without compromising performance, even during peak demand. By integrating HPE technology into its managed service, SITA’s customers get a network that is centrally operated by SITA while retaining the flexibility to use different technologies and vendors.
Available in more than 145 countries, with 24/7 operational support, SITA assured that by reducing the need for costly hardware and simplifying operations the network lowers both upfront investment and ongoing costs. Its pay-as-you-go model allows customers to scale usage up or down based on demand, with rapid deployment across locations.
This is said to reduce the need for on-site support, spare equipment and recurring training, freeing up IT teams to focus on higher-value activities. Where needed, the campus network connects to SITA’s global wide-area network services. This connectivity links more than 600 airports worldwide.
As is the norm with other leading networking solutions, the SITA Campus Network uses AI to improve visibility across the network, detect issues earlier and automate troubleshooting, helping reduce downtime. It also provides centralised management, allowing infrastructure and devices to be monitored and controlled across both on-site systems and remote environments.
Martin Smillie SITA senior vice-president of communications and data exchange, said integrating diverse systems and devices across airport environments is becoming more complex as operations become more connected: “At the same time, expectations on performance, resilience and security continue to rise. With SITA Campus Network powered by Aruba, we take on that complexity. We deliver a network that is set up, run and continuously optimised, so our customers can focus on keeping operations moving while maintaining control across increasingly demanding environments.”
Sujai Hajela, executive vice-president and general manager for enterprise campus and branch at HPE, added: “Airports and airlines have to support thousands of staff, passengers and mission critical systems across terminals, gates and airside areas – and any network issue shows up immediately as delays and frustration.
“SITA Campus Network powered by HPE Aruba Networking is built on our secure, AI-native technology to deliver a self-driving network that spots and fixes problems in real time, often before anyone notices, so operations keep moving and passengers stay connected.”
