Reencle Prime is the pick if you want an end product you can actually call compost — it uses live microorganisms instead of just heat, so it keeps working (and smelling like nothing) between top-offs. Lomi 2 is the fastest and most flexible for households that just want food waste off the counter and out of the trash bag. The Vitamix FoodCycler FC-50 is the budget entry: a simpler, cheaper machine that does the same core job — heat, grind, dry — without Lomi’s extra modes. All three countertop composters shrink food scraps in hours instead of months, but only one of them produces something a university extension office would call finished compost.
At a Glance: Which Countertop Composter Fits Your Kitchen
- Best overall: Reencle Prime — continuous-feed design, real microbial composting, no daily cycle to manage. Downside: bigger footprint, higher up-front price.
- Best for speed and features: Lomi 2 — three modes (Eco-Express, Lomi Approved, Grow), fastest turnaround. Downside: default mode makes grounds, not compost.
- Best budget pick: Vitamix FoodCycler FC-50 — lowest price of the three, same basic dehydrate-and-grind approach. Downside: fewest features, filters add up over a year.
What These Countertop Composters Actually Do
All three machines take food scraps — the stuff that would otherwise sit in a trash bag getting smelly — and process them into a smaller, dry, mostly odorless byproduct in a matter of hours. That’s the shared pitch, and it’s real: none of these require a backyard bin, turning a pile, or waiting months.
Where they diverge is what happens inside the bucket. Lomi 2 and the Vitamix FoodCycler FC-50 both use heat, grinding, and airflow to dehydrate and pulverize scraps — a process closer to a food dehydrator than a compost pile. Reencle Prime instead keeps a bed of live microorganisms working continuously, so scraps you add each day are actually broken down biologically, not just dried out. That distinction matters more than any spec sheet number, and we’ll come back to it in the dealbreakers section below.

The Real Year-One Cost: Machine, Electricity, and Filters
Sticker price is the least interesting number here. What none of these brands print on one page is the combined cost of running the thing for a year — power draw plus the carbon filters and, for Reencle, the microbial culture top-off. We built the table below from each brand’s own published wattage and refill pricing, assuming five uses a week for the batch machines (Lomi, FoodCycler) and continuous daily operation for Reencle, priced at $0.16 per kWh — the approximate U.S. national average residential rate.
| Lomi 2 (Eco-Express) | Vitamix FoodCycler FC-50 | Reencle Prime | |
|---|---|---|---|
| Machine price | $499 | $400 | $499 |
| Est. annual electricity | ~$25 | ~$33 | ~$40 |
| Est. annual filters/consumables | ~$289 | ~$87 | ~$50 |
| Year-one total | ~$813 | ~$520 | ~$589 |
The math flips the usual assumption. Lomi 2 looks similarly priced to Reencle at checkout, but its filter cadence — a roughly $50 pack good for about 45 cycles, per a cost comparison from GEME — makes it the most expensive of the three to actually run for a year if you use it several times a week. The FoodCycler FC-50 stays cheapest overall mainly because it launched at a lower price to begin with. Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.
Grounds vs. Real Compost: The Dealbreaker Most Listings Skip
Here’s the part that matters most and gets glossed over in a lot of marketing copy: Lomi’s default mode and the FoodCycler FC-50 don’t produce finished compost. They produce sterilized, dehydrated food powder. According to the Illinois Food Scrap & Composting Coalition, dehydrators “use heat to kill bacteria and microbes, essentially sterilizing the material,” with “no decomposition or microbial activity involved” — meaning the output lacks the living organisms that build actual soil health.
That doesn’t make Lomi or the FoodCycler useless — the grounds are still a legitimate landfill-diversion win, and both brands recommend mixing the output into an outdoor compost pile or soil at a 10–20% ratio to let real decomposition finish the job. Lomi’s Grow mode, run with its proprietary pods, gets closer to true active compost, but the company’s own guidance still says to blend it with existing soil rather than apply it directly. Reencle Prime is the outlier: because it relies on continuous microbial digestion rather than heat-drying, independent reviewers have consistently described its output as usable, living compost rather than a pre-compost intermediate. If your goal is actual garden-ready soil amendment and not just a smaller trash bag, that’s the difference that should decide this comparison.
Lomi 2: Best for Speed and Flexibility
Lomi 2 is the fastest of the three on its Eco-Express setting — as little as 3 hours per batch — and it’s the only one offering a dedicated “Lomi Approved” mode that can handle some bioplastics and eggshells most composters choke on. That flexibility is genuinely useful for households juggling mixed food and packaging waste.
Pros: fastest cycle option, three distinct modes for different waste types, compact breadmaker-sized footprint.
Cons: smallest batch capacity of the three (2 liters), highest year-one running cost due to filter cadence, default output is grounds rather than true compost.
Best for: renters and apartment dwellers who want the quickest possible turnaround and don’t have outdoor garden space to finish the compost themselves.
Vitamix FoodCycler FC-50: Best Budget Pick
The FC-50 does the same core job as Lomi’s Eco mode — heat, grind, dehydrate — at a lower entry price and with a simpler single-mode interface. It’s a sensible choice for anyone who wants the trash-reduction benefit without paying for features they won’t use.
Pros: lowest sticker price, largest per-batch capacity of the batch-style machines (2.5 liters), straightforward one-button operation.
Cons: no alternate modes, output is dehydrated grounds only, filter cost adds up over a full year of regular use.
Best for: budget-conscious households who mainly want less smell in the kitchen trash and don’t need garden-ready compost.
Reencle Prime: Best for Real Garden Compost
Reencle Prime works differently by design: you feed it daily like a mini compost pile, and a bed of live microorganisms does the actual decomposition, continuously, rather than in discrete batches. That’s why it’s the only one of the three whose output most independent reviewers treat as genuine finished compost rather than a pre-compost intermediate.
Pros: produces real microbial compost, largest holding capacity (14 liters), lowest ongoing filter/consumable cost of the three.
Cons: no discrete “done” cycle to point to, larger unit takes up more counter real estate, priciest to buy outright alongside Lomi.
Best for: anyone with a garden or houseplants who actually wants to use the finished output, not just divert scraps from the trash.

FAQ
Is the output from a countertop composter the same as real compost?
Not always. Lomi 2’s default mode and the Vitamix FoodCycler FC-50 both produce dehydrated, sterilized food grounds — useful for cutting trash volume, but not the biologically active humus that true composting produces. Reencle Prime, which uses live microorganisms instead of heat-drying, is the one of the three whose output is widely treated as genuine finished compost.
Which countertop composter is cheapest to run over a year?
Based on our year-one cost breakdown combining machine price, electricity, and filter or consumable costs, the Vitamix FoodCycler FC-50 comes out cheapest at roughly $520, followed by Reencle Prime at roughly $589. Lomi 2 runs highest at around $813 mainly due to its filter replacement cadence.
Do these machines smell while running?
All three use carbon filters to control odor during operation, and reviewers across independent outlets consistently describe them as low-odor to odor-free in normal use. Filters need periodic replacement — every 3–4 months for Lomi 2 and the FoodCycler FC-50, roughly annually for Reencle Prime — to keep that performance up.
Can I put meat, dairy, or bones in these composters?
Capabilities vary by brand and mode, so check each manufacturer’s current accepted-materials list before use. As a general safety note, none of these appliances should be run unattended for extended periods or used with materials outside their stated guidelines, since that can affect both performance and the electrical safety of the unit.
Bottom Line
If you want a machine that produces something you can actually spread on a garden bed, Reencle Prime is the clear standout among these three. If speed and flexibility matter more than finished compost, Lomi 2’s multiple modes earn it a spot. And if you just want food waste out of your kitchen trash for the least money, the Vitamix FoodCycler FC-50 gets the job done without the extras.
