Frequently Asked Questions
In the most recent round of testing (January 2025), we subjected each device to a “torture test” by intentionally not following instructions: loading produce in the wrong order, failing to chop ginger or pineapple, and leaving the lemon in its peel, to see which devices spun fruitlessly or got tragically jammed with fibers and pulp.
We test each device with a decibel meter, noting whether it’s louder or quieter than the 65 decibels it reaches during polite conversation. And we rate each appliance for ease of cleaning.
A few 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 slow masticating juicers also known as “cold press”.
A centrifugal juicer Offers speed and lots of power. In essence, it works like a blender with an additional mesh screen to separate the juice from the pulp. A rapidly rotating blade breaks up the fruits and grinds them against a mesh screen, often at speeds of thousands of revolutions per minute. Whatever passes through the net is juice.
The power and speed mean that centrifugal juicers are often quick to process roots, pineapples and other hard or dense fiber products that can cause difficulty for slow pressing augers. Soft fruits such as berries or green leafy vegetables will not do so well here, resulting in reduced juice yield or even clogging of the mesh screens. Given the high agitation, centrifugal juicers also produce frothy juice. That said, spinning faster also makes them faster.
A masticating juicer-Sometimes called a “slow” or “cold press” juicer – this is the newest trend in juicing and is also a very old technology. Basically, slow juicers work on the same principle as an old-fashioned cider mill, slowly “chewing” and pressing the fruits at a much lower rate, which some believe subjects the fruits and vegetables to less oxidation and heat and thus preserves more of their essential character.
More reliably, slow juicers produce higher juice yield and less waste than centrifugal juicers and are particularly more effective on leafy greens, soft fruits and berries. They also add less foam 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 extract juice throughout the process. More recently, the advent of vertical masticating juicers from South Korea changed everything – any juicer with a large hopper can load, shrug, and walk away while it does its job. Most of the juicers 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 oranges, lemons and limes drinks. These are fairly simple devices and are mostly similar to each other apart from styling and ergonomics. Basically, you press a half-cut citrus fruit onto the raised dome of the reamer and turn the device on. The reamer will continue to rotate until the juice comes out.
Masticating and centrifugal juicers can, of course, juice unpeeled citrus fruits – and the added zest of lemons and limes can be quite tasty. (Actually, that’s my preference.) But to avoid this kind of excitement, you’ll need to peel your citrus before loading it into the juicing chamber. The easiest way to juice an orange will always be to halve it and press it against the raised dome of the citrus juicer.
Are juicers good for your health?
Juicing is an easy way to include more fruits and vegetables in your diet, but it’s not magic. There are some easy ways to maximize the health benefits and minimize drawbacks like blood sugar spikes.
WIRED contributing reviewer Emily Peck talks to nutritionist and UK wellness brand founder Kylie Zane Sana Kalyan (unrelated to Korean juicer brand Sana Products), for their advice on healthy juicingYes. Here are five ways to make sure juicing is a healthy addition to your life and avoid sugar overload.
- Balance of fruits with vegetables: Fruits can contain a lot of sugar, so to combat this, make vegetables the base of your juice. Aim for a ratio of 80 percent vegetables and 20 percent fruits. Consume spinach, kale, cucumber, celery, ginger and beetroot. When adding fruit, choose low-glycemic index fruits like green apples, berries and pears.
- Fiber Include: Juicing removes most of the fiber from fruits and vegetables, but it’s important for slowing sugar absorption, aiding digestive health, and keeping you feeling full. Consider mixing some of your juices with whole fruits or vegetables to retain some fiber. Alternatively, add a fiber supplement or incorporate some pulp into cooking or baking to make sure you’re getting enough.
- Add healthy fats: To stabilize blood sugar levels and increase satiety, include sources of healthy fat, such as avocado or coconut oil, into your juicing routine.
- Improve with “Superfoods”: Matcha and collagen are popular supplements that can be easily added to juices for an added health boost. A teaspoon of matcha is rich in antioxidants and provides a mild boost of energy without the jolt of caffeine. Collagen can help with skin elasticity and hydration, as well as healthy hair, nails, and joints.
- Choose the right time to drink juice: Drinking juice on an empty stomach can sometimes cause blood sugar levels to rise rapidly. It is often better to drink juice as part of a meal or after eating some solid food, especially foods high in fiber, protein or fat, to help slow the absorption of sugar.
Which juicer accessories are important?
Once you’ve decided what ingredients you want to put in your juicer – whether it’s hard fruits or leafy vegetables – it’ll be easy to choose between a chewier “slow” juicer or a faster centrifugal design. Either way, it is 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 cream and sorbets – you’ll need a juicer with the corresponding food processing parts.
Also consider how much you are willing to prepare your content. While you may find regulations on the size of the feeding chute for safety reasons, some juicers are equipped to take a whole apple in one, meaning less chopping. To make it even simpler, most modern slow juicers, such as Nama and Hyrom, have self-fill hoppers.
Dishwasher-safe parts are practical and save scrubbing time, but please be aware, even the easiest-to-clean juicer will take time and attention to clean. The pulp, peel, pulp and juice are sticky and messy. That’s just the way it is.
The reverse button is another useful feature, especially with slower juicers. This allows you to reverse the juicing process if you crowd your juicer too eagerly and ingredients get stuck.

Tribest SlowStar AI Vertical Hopper Juicer for $600: I’m still testing the full capabilities of this brand new appliance from Tribest – probably the most interesting new juicer of the last few years. While the rest of the kitchen got smart, most juicers remain entirely analog. But this Tribest is a touchscreen device with preset spin speeds for individual vegetables and an AI-controlled function that regulates the spin speed based on the resistance of each produced item. It seems to be working, making this thing an absolute beast for pitching through tough lemon peels or ginger. so far so good! But there are some compromises, including a smaller hopper size and less 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 easy to clean and reassemble as the Hurom H70, and there are more parts to keep track of. And so on initial testing, it remains just below the top-pick range, as I’m constantly discussing 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 big batches without having to load up an extra batch of carrots or spinach. The extra liter of space over the J2 will matter to some power users. The stainless steel blade and additional strainer on the AUTO10 Plus upgrade are also nice touches. But this size comes at the cost of bulk and height – making it difficult for most kitchen counters. Although it’s a slightly higher wattage machine than the Kuvings Nama J2, the versatility of the J2’s multiple hoppers and accessories, and its US-based customer service, give the Nama a slight edge. But if you know you’re a big-batch juicer, you won’t go wrong with this Kuvings.

Omega Juicer VSJ843RR for $399: WIRED contributing reviewer Emily Peck tested and recommended this juicer in previous editions of this guide, praising its excellent juice and high yield. But the appliance is less intuitive than the current generation of high-end juicers, with leafy vegetables requiring a bit of a fidget to push through the feeder tube, and the appliance struggling with fibrous vegetables like pineapple and broccoli.

Sana 707 Cold Press Juicer for $200: This is a classic horizontal juicer, this style has been around for a long time since last century. It offers a lot of versatility, with attachments for anything from coffee to pasta. And it’s economical compared to hopper-style juicers. But like other lean-faced feeders, you’ll find yourself hand-feeding carrots and celery and small apple chunks to make juice batches.
Omega Time-Saving Batch Juicer for $226: Wired previously recommended this set-and-forget model from Omega as a budget slow juicer, despite less performance than top picks that cost twice as much. But after seeing some consumer feedback about durability we’ve put it back on the test bench, and we’re now more likely to recommend this fast-spinning centrifugal juicer as a budget option.
Omega Juicer Wide Mouth Cold Press Juicer JC4000 for $135: On the one hand, this Omega wide-mouth slow cold-press juicer is quite affordable. But it’s also very difficult work to gather properly, it leaves a considerable amount of pulp unremoved, and despite its “wide mouth” name, feeding fruits through its vertical feeder that aren’t carrots or celery requires quite a bit of chopping – at least compared to newer-model hoppers. This will get the job done, without spending too much money. But you may not be 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 available on Amazon, but it’s listed as discontinued on Sana’s site. The feeder-tube style of the 868 is not in vogue at the moment, but the utility of this appliance comes from the low cost and thick screen that allows this appliance to be used for both juicers and smoothies. That said, if you make smoothies most of the morning, the blender is very easy to clean.
