Description
The Chulux CL-CM24002 Slim is a capsule single serve brewer built around two numbers: it is roughly four inches wide, and it will take a travel mug 7.3 inches tall with the drip tray removed. Those two figures together describe a machine designed for people who drink from a large flask and have almost no counter to put a brewer on.
It carries roughly 569 published ratings at a 4.2 average since March 2024, and it sits in our single serve brewers category as one of the narrowest machines available. Two published figures on this listing deserve close reading before anything else.
The 190 Degree Figure
Chulux states that the machine reaches its ideal temperature of 190 degrees Fahrenheit in two minutes.
Publishing a temperature at all is rare in this category and deserves credit. The number itself is below the accepted brewing range: extraction is generally held to happen properly between roughly 195 and 205 degrees Fahrenheit, and the Specialty Coffee Association standard sits inside that band. One hundred and ninety degrees is five degrees under the bottom of it. In practice that is close enough to produce a drinkable cup, and much closer than several machines in this bracket manage, but it is not the ideal temperature the listing calls it, and a slightly cooler brew extracts less from the same coffee.
The 4,000 Foot Limit
A note at the end of the description reads: “Only available at elevations below 4,000 feet”.
That is a real limitation and it is lower than most. Water boils at a lower temperature as altitude rises, so a machine with a thermostat calibrated near sea level can cut out early or fail to pump properly in the mountains. What makes this figure notable is that another current Chulux machine states 6,000 feet as its limit, so the two are not interchangeable. If you live at altitude, check the specific model rather than assuming the brand behaves the same way throughout its range. Denver, Santa Fe and Albuquerque are all above 4,000 feet.
Mug Clearance in Three Positions
This is the strongest part of the design and it is documented properly. The machine takes a mug 7.3 inches tall with the drip tray removed, 6.2 inches with the tray in place, and 4.3 inches with the tray adjusted upward. Three published figures for three configurations is better documentation than machines costing five times as much provide.
The three position tray also solves the small cup problem. A short espresso style cup under a tall spout produces a long drop and a splashed counter, and raising the tray closes the gap. Owner feedback confirms both ends work as described.
Width, and a Number That Does Not Match
Chulux markets the machine as just 4 inches wide. The specification table gives 4.4 inches. The difference is trivial in use and worth naming anyway, because a listing that rounds its own headline number down is telling you how the rest was written. Either way, under four and a half inches is genuinely narrow, and the machine measures 9.7 inches deep by 8.98 inches high at 2.6 pounds.
Capsules, and the Filter That Is Sold Separately
The machine takes both generations of standard capsule. For loose coffee, Chulux states that a reusable filter is required and that it is sold separately.
That is an important difference from other machines in the same family, some of which include a grounds basket. Read the included components list carefully, because it lists a removable drip tray, the machine, a stainless drip tray cover, a manual and a water filter, but no coffee filter. If using your own ground coffee is part of why you are buying, budget for the accessory, and be aware that the listing does not identify which reusable filter fits. That accessory is also what decides the running cost, because capsules are among the most expensive ways to buy coffee per ounce and the prices in our single serve capsules and pods section are a far larger number over a year than the machine itself.
Fresh Water Every Brew
There is no reservoir. You pour in the amount of water you want, the machine heats and pushes all of it through, and the cup size is set by what you poured rather than by a button. Chulux publishes the fill area depth as 2 inches, which is a small detail that makes filling from a jug easier.
The consequence is the same as on every machine of this type: nothing sits in the machine between uses, there is no standby draw and no stale water, and you cannot brew twice without going back to the tap. The four hole needle Chulux advertises spreads the water across the capsule rather than drilling a single channel through the middle of it, which is a sensible design point on a fixed dose of coffee.
Cleaning and Descaling
Chulux recommends descaling with vinegar, citric acid or a proper descaler every one to two months depending on how often you brew, and says so in the listing rather than leaving it to the manual. There is no descale reminder light, so the schedule is yours to keep.
On a machine with a narrow flow path and no water filter this is the maintenance that decides how long it lasts. The symptoms of neglect are a brew that slows, a machine that heats without pumping, and eventually nothing at all.
What the Specifications Do Not Settle
No wattage is published. No warranty term appears in the table. Which reusable filter fits is not stated. The included components list mentions a water filter, while the description says nothing about water filtration anywhere, so what that item actually is remains unclear. “Specific Uses For Product = Americano” is a drink name filed into a specification field.
One caution about reading the reviews. Several of the five star reviews on this listing are written in polished marketing language, opening with phrases about excellent additions to any kitchen or office space and solid craftsmanship. Those read as promotional copy rather than as owner experience, and they inflate an average that the more specific reviews, such as the owner who simply wishes the machine were taller, do not support to the same degree.
Who It Suits
This suits somebody who fills a tall travel mug every morning, has a four inch gap to put a machine in, lives below 4,000 feet, and is content brewing from capsules. The three published mug clearances and the stated brew temperature are better documentation than this price bracket usually offers.
Look elsewhere if you want a grounds basket in the box or a reservoir. The Chulux QF-CM801 includes a grounds filter and allows 6,000 feet, the Chulux LC-CM54802 is the newer machine in the same range, and the Keurig K-Slim is the brand alternative at a similar width with a tank behind it.
