I’ve spent way too many hours of my life standing over a stove waiting for cannabutter to finish, so when infuser machines started showing up everywhere, I had to see if they actually lived up to the hype. I’ve bought a few, borrowed a few more, and spent the better part of a year making everything from rosemary oil to some genuinely questionable holiday cookies. Everyone had fun though!

This list has changed a lot since I first put it together. I’ve pulled two machines that just aren’t holding up anymore, and I’m adding a brand-new one that runs on a completely different piece of technology than everything else here. Here’s where things actually stand right now.

TRENDSICLE'S TESTING CRITERIA

Since I did my own first-hand and independent testing, I came up with the following criteria to help determine which infusers I felt made my list.

Precision/control — dual decarb modes (THC vs CBD), app control, ability to bake in-chamber
Speed / cycle time — hours vs minutes
Capacity / batch size — 1 oz up to 10 cups
Price / value — markup vs features
Ease of use for beginners — low stakes, hard to mess up
Odor control — carbon filter, view window vs closed box
Smart features / connectivity — WiFi, Bluetooth, touchscreen, or none
Track record & reliability — years of real owner feedback
Independent evidence — used as the removal criterion (ECRU got cut for having no verifiable outside independent reviews)

For the Person Who Wants One Machine That Does Everything Well

LĒVO II+

$312.55 Best Overall $300+

This is still the one I hand people first. After running all five side by side, it's the only machine that's genuinely good at every step instead of nailing one and phoning in the rest: it dries, decarbs, infuses, and dispenses, and the full active cycle takes about 30 minutes, which is fast for this category. The 16 oz reservoir handles a real batch (two cups of oil or butter), the ceramic-coated basin is non-stick and Teflon-free, and every removable part is dishwasher-safe, so cleanup isn't the chore it is on the cheaper units. The upgraded coconut-husk carbon filter in the lid is the real difference though: it cuts the smell down noticeably more than the old LEVO II did, whether you're infusing cannabis or just making rosemary olive oil. It's not the cheapest here, but it's the one I'd buy if I could only own one.

👀 Not So Great

It's the priciest "standard" option on this list, and several owners report needing to stay on top of cleaning or the pods start to clog.

For the Person Who Wants Precision Over Pure Convenience

Ardent FX

$299.00 Best Versatility $200-300

The FX is the one I reach for when potency is the whole point. It's less of a countertop appliance and more of a precision decarb-and-infuse chamber, and it shows: in my testing it activated flower more completely than anything else here, which is the difference between edibles that actually work and edibles that let you down. It holds up to 4 oz of herb, runs preset cycles for decarb, infusion, and even baking small-batch edibles right in the vessel, and the Bluetooth app lets you build custom time-and-temp programs if you want to dial in a specific cannabinoid. The tradeoff is capacity and cleanup: the vessel is smaller than the big batch machines and there's no dispensing spout, so you're pouring and scraping by hand. But if you care more about getting every last bit of THC or CBD activated than about volume, this is the most potent-per-gram machine I tested.

👀 Where It Falls Short

4 ounces of herb is a genuinely small ceiling if you want a big batch, and running decarb, infuse, and bake back to back takes a while.

For the Person Tired of Waiting Hours for a Batch

Altafuse ALTA1

$329.00 Fastest / New This Year $300+

This is the newest idea in the category, and the one I was most skeptical of going in. Instead of just heating and stirring, the ALTA1 uses ultrasonic waves to drive the infusion, and the pitch is faster, more potent results at lower temperatures. In practice it did run noticeably quicker than the traditional heat-and-stir machines, and the lower-temp approach is genuinely appealing if you worry about cooking off terpenes and flavor. It holds up to 1 oz (30g) of flower, has a built-in scale so you can weigh your herb right on the machine, and the airtight lid did the best job of any unit here at keeping the smell contained. Every part is dishwasher-safe, and the touchscreen is the most modern interface of the bunch. It's a newer, pricier bet, but if you want the fastest, coolest-running infusion with the least odor, it's the most interesting machine I tested.

📌 Worth Knowing

Being newer means it doesn't have the decade of reviews and track record that LĒVO and Ardent do. If long-term reliability data matters more than speed, that's a real trade-off.

For the Person Whose First Question Is Always About Price

STX Infuzium

$149.75 Best Budget / Large-Batch Under $200

If you cook in volume, this is the workhorse. The Infuzium is built around a big 4-cup stainless reservoir and a 15,000 RPM mixer, so it churns through large batches of butter or oil (anywhere from 1 to 5 cups) without breaking a sweat, which none of the smaller all-in-ones can match. It runs five presets for butter, oil, and tinctures plus a full DIY mode where you set your own temperature and time, and the digital display keeps you posted on both. It's the least glamorous machine here: no app, no ultrasonic wizardry, and you'll decarb your flower separately since it's really an infuser first. But it's also one of the most affordable ways to make a lot of infusion at once, and in my testing the powerful mixer pulled a strong, even infusion every time. For big families of edibles or anyone batch-cooking for the week, it's the value pick.

👀 The Catch

There's no built-in decarb cycle, so cannabis specifically needs to be activated in an oven first. No app, no smart features at all.

For a First-Time Infusion or a Small Personal Batch

Hello High Ultra Infuser

$210.99 Best for Beginners $200-300

This is the one I'd hand a first-timer. The Ultra Infuser keeps things refreshingly simple: it decarbs and infuses in one pot, handles 1 to 3 cups of butter or oil, and it's genuinely all-in-one, so you go from raw flower to infused butter without juggling separate steps or gear. It comes with a butter mold and a silicone spatula set in the box, and yes, you can use it to make the base for gummies too, which my testers had fun with. The non-stick pot wipes clean easily and the removable parts are dishwasher-safe. It's not the most powerful or the most precise machine here, and heavy users will outgrow the batch size, but it nails what beginners actually need: an approachable, affordable machine that makes a solid batch of infused butter with no learning curve. If you're new to this and want to make edibles without overthinking it, start here.

👀 The Real Limitation

The 3-cup batch ceiling means this isn't the machine for a big batch or gifts for a group.

What We Removed From This List (August 2026), and Why

ECRU Herbal Infuser

We're removing this one for a simple reason: we could no longer find enough independent, real-world evidence that it holds up. It has almost no outside press or reviews beyond its own product pages, and its social following is small enough that we can't verify the claims the way we can for machines with years of real owner feedback behind them.

Hello High Magic Butter Maker (the specific older model)

We're not removing Hello High, we're upgrading which of their machines we recommend. The brand's own newer Ultra Infuser is meaningfully better, with a view window and sturdier glass canister that the older version didn't have.

Frequently Asked Questions

What is decarboxylation, and do I actually need it? +

It's heating raw cannabis just enough to activate the compounds inside it, without it, THC stays as inactive THCA and won't do anything when eaten. You need it for raw cannabis flower specifically; you don't need it for straightforward culinary infusions like rosemary or basil oil.

Can any of these make alcohol-based tinctures? +

Most can, with a real caveat: LĒVO doesn't officially support alcohol, since alcohol vapor near a heating element is a fire risk. Ardent, STX, and Hello High can all handle tinctures on their standard cycles.

Which one is best if I've never done this before? +

Hello High Ultra Infuser for a genuine first try, small batch, hard to mess up, or STX Infuzium if you want to go bigger right away. Both skip smart features entirely, so there's less to figure out on day one.

Do I need an app-connected machine, or is that just a gimmick? +

It's genuinely useful on LĒVO (monitoring remotely, saved settings) and Ardent (switching modes without walking back to the kitchen). On STX and Hello High, you don't miss much since the cycles are simple enough to check on physically.

Can I use any of these for non-cannabis herbs? +

Yes, every machine on this list works for ordinary culinary herbs too: rosemary, basil, lavender, even coffee beans for infused oils. Cannabis is the most talked-about use case, but it's not the only one.

The Bottom Line: None of these five are interchangeable, they're built for different priorities. LĒVO II+ if you want one machine that does everything well. Ardent FX if precision and versatility matter more than speed. Altafuse ALTA1 if you are tired of waiting hours for a batch. STX Infuzium if you want the best value for big batches. Hello High Ultra Infuser if you just want a low-stakes way to try this for the first time.
