The best electric composter depends on what you want at the end. If you want real compost made by microbes, the Reencle Prime is the standout: it digests up to 2.2 pounds of scraps a day, runs at a stated 28 dB, and is designed to produce compost rather than dried scraps. If you mainly want to shrink food waste fast and keep the trash from smelling, a dryer-grinder food recycler such as the FoodCycler Eco 5 does that in hours, with the largest bucket in its class. Smaller households should look at the Reencle Essential or the compact FoodCycler Eco 3. Below we compare seven current listings, explain the difference between microbial composters and dehydrators (the category that includes Lomi- and Mill-type machines), and cover noise, odor and what to do with the output.

How we compared: we compared 7 current Amazon listings on what each listing states (process type, bucket capacity, cycle time, stated noise level, filters and accepted foods). We did not test or handle the products, and availability and models change.
Key Takeaways
- There are two kinds of “electric composter.” Dryer-grinders heat and grind scraps into a dry, reduced material in hours. Microbial units keep a living culture that digests scraps over days.
- Dryer output is not finished compost. Mix it into soil or a compost pile and let it break down before using it around plants.
- Stated noise ranges from under 30 dB for microbial units to roughly 40 to 50 dB for dryers.
- Bucket sizes on this shelf range from 2.5 to 5 liters for dryers; Reencle units handle up to 2.2 pounds of scraps per day.
- Every model uses carbon filters that need periodic replacement. Factor that into long-term running costs.

Electric units are one way to deal with kitchen scraps; a simple pail and an outdoor pile is another. Our composting and soil guide lays out every method, and our picks for the best countertop compost bins cover the low-tech option.
1. Reencle Prime — Best for Real Microbial Compost
A 14-liter microbial kitchen composter that digests up to 2.2 lb of scraps a day with 3-layer filtration at a stated 28 dB.
Check price on AmazonWhy We Like It

- Quietest stated noise on this shelf
- Three-layer odor filtration
- Comes with starter microbes, filter and shovel
| Specification | Details |
|---|---|
| Process | Aerobic microbial decomposition |
| Capacity | 14 L unit; up to 2.2 lb food scraps per day |
| Noise | As low as 28 dB |
| Filter | 3-layer filter system; 1 carbon filter included |
| Weight | About 20 lb |

Reencle Prime — compressed specs
Reencle works differently from most machines on Amazon. Instead of heating scraps until they are dry and grinding them, it maintains a warm, aerated chamber of living microbes that break down food continuously. You add scraps through the day, and the culture consumes most of them, leaving a smaller amount of compost-like material that you remove periodically. The listing describes the output as nutrient-rich compost rather than dried waste.
It is the tallest and heaviest unit here at over 18 inches and about 20 pounds, so measure under your upper cabinets. Because it runs continuously rather than in discrete cycles, it suits households that produce a steady stream of scraps. Its stated 28 dB is close to a quiet library, far below the dryer-grinders.
Pros
- Produces compost, not dried scraps
- Very quiet
- Continuous feeding through the day
Cons
- Tall, may not fit under cabinets
- Daily capacity limit around 2.2 lb
- Living culture needs regular feeding

2. FoodCycler Eco 5 — Best Large-Capacity Food Recycler
A dryer-grinder food recycler with a 5-liter removable bucket and patented grinding system that handles pits, peels and bones.
Check price on AmazonWhy We Like It
- Biggest bucket among the dryers here
- Grinds pits, bones and leftovers

| Specification | Details |
|---|---|
| Process | Drying and grinding (Vortech system) |
| Bucket | 5 liters |
| Volume reduction | Close to 90 percent, per listing |
| Filter | Refillable carbon |

FoodCycler Eco 5 — compressed specs
FoodCycler is one of the best-known names in electric food recyclers, and the Eco 5 is its big-family model. Load the 5-liter bucket through the day, start a cycle, and a few hours later the scraps are a dry, reduced material. The listing says its grinder handles pits and bones, which many smaller dryers cannot. FoodCycler is candid in its own listing that it is a “composter alternative”: what comes out is dried food, not compost.
At about 30 pounds it is the heaviest dryer here, and a stated noise level is not given. For a family that cooks a lot and wants scrap volume cut down fast, its capacity is the main reason to choose it over the Airthereal or Assark.
Pros
- Large 5-liter capacity
- Handles harder scraps
- Established brand
Cons
- Output is dried waste, not compost
- Heavy unit
- Noise level not stated

It also takes meat, fish and dairy, which backyard piles handle poorly.
Pros
- Very quiet
- Takes foods a pile cannot
- Clear guidance on using output
Cons

Airthereal R500 — compressed specs
The Airthereal’s routine is easy to build into a day: collect scraps in the bucket, start it at bedtime, empty a dry powder in the morning. The listing is straightforward that the powder can go to plants or simply in the trash to cut volume and odor. Its bucket is the smallest on this shelf, so it suits light cooks.
Pros
- Very easy to use
- Dishwasher-safe bucket
- Lighter than FoodCycler models
Cons
- Smallest capacity here

Assark 3L Electric Composter — compressed specs
Among the dryer-grinders whose listings state a noise level, the Assark’s under-40 dB claim is the lowest; Soliddis and Homfan list about 48 dB. Its lid-open pause is a sensible safety feature in homes with kids, and the slim width suits narrow counters.
Pros
- Quietest stated dryer

Ouaken 4L Electric Composter — compressed specs
Ouaken gives you a choice between a quick crush cycle that mainly cuts volume and a longer ferment cycle intended to produce better fertilizer. The 4-liter bucket sits between the Eco 3 and Eco 5, and the filter life is the longest stated among the dryers here. It also comes in black.

What to Look For in an Electric Composter
Dryer-grinder vs microbial
Most machines sold as electric composters, including the Lomi- and Mill-type units you may have seen advertised, are dryer-grinders. They are fast, shrink scraps dramatically and remove odor, but the result is dehydrated food that will rehydrate and decompose when mixed into soil. Microbial units like Reencle are slower but closer to real composting. Choose a dryer if your goal is less trash and no smell; choose microbial if you want garden-ready material.
Noise
Dryers run fans and grinders for hours. Stated levels on this shelf run from under 30 dB (Reencle) to around 48 dB (Soliddis, Homfan), roughly quiet-room to refrigerator hum. In open-plan homes, run dryers overnight or while out.
Running costs
Budget for carbon filter replacements and electricity. Filter intervals on this shelf range from about 3 months (Assark) to 9 to 12 months (Reencle Essential). Dryers use more energy per cycle than microbial units, which run continuously at low power.
Using the output
Do not spread dryer output straight onto plants as if it were finished compost. Mix it into a compost pile or dig it into garden soil at a modest rate and let it break down for several weeks. For other low-space methods, see our bokashi composting guide and vermicomposting guide.
Frequently Asked Questions
Do electric composters really make compost?
Microbial units such as Reencle produce compost-like material. Dryer-grinders produce dried, ground food that still needs to decompose in soil or a pile before it acts like compost.
Are electric composters noisy?
Stated levels on this shelf range from about 27 dB for Reencle to about 48 dB for some dryers, roughly a whisper to a quiet refrigerator.
Can you put meat in an electric composter?
Some can. The Reencle Essential listing accepts meat, fish and dairy; FoodCycler listings mention bones. Check each manual, since many dryers limit large bones, pits and oily foods.
Do electric composters smell?
They use carbon filters to control odor. Smells usually mean a filter is due for replacement or the bucket needs cleaning.
Is an electric composter better than a compost bin?
It is faster and works indoors without a yard, but it costs more to buy and run. If you have outdoor space, a regular compost bin or tumbler makes more compost for far less.
