The Momcozy Sterilizer and Dryer BS01 is a three-layer baby bottle sterilizer that uses steam, heated-air drying, and a 24-hour storage mode to simplify feeding equipment care. Momcozy says its steam cycle takes 9 minutes and reduces 99.9% of germs. The machine also includes dedicated holders for breast pump parts and adjustable drying times.
Its biggest advantage is handling bottles, nipples, pacifiers, and pump accessories in one appliance. However, it does not wash away milk residue, takes up countertop space, and needs regular cleaning. This review explains what the BS01 actually offers, its limitations, and which households will benefit most.
QUICK VERDICT
Momcozy 3 Layers Sterilizer and Dryer BS01
Editorial rating: 8/10 (research-based assessment, not hands-on testing)
Best for: Parents who regularly wash multiple bottles or pump parts and want automated drying afterward.
Skip if: You need a machine that washes bottles automatically or have very little counter space.
Bottom line: A practical choice for frequent bottle and pumping routines, provided you understand that washing remains a separate step.
Before You Buy: Four Things to Know
- It does not wash bottles. Remove all milk residue before sterilizing.
- Capacity varies. Large bottles and wide pump components take up more space than small bottles.
- Steam-safe items only. Check each bottle, nipple, toy, and pump component before exposing it to high heat.
- Check electrical compatibility. Momcozy lists the BS01 US version as 120V/60Hz. Do not assume that it supports international voltages.

Key Takeaways
- Momcozy BS01 offers steam sterilization, hot-air drying, and covered storage in one three-layer machine.
- The standard bottle sterilization cycle takes 9 minutes, according to Momcozy, but a complete sterilize-and-dry program takes longer.
- Capacity ranges from about 6 larger bottles to 12 smaller bottles, depending on size and loading arrangement.
- A dedicated breast pump mode and removable racks make it useful for pumping households.
- Its 24-hour storage setting periodically runs a drying cycle to help manage moisture.
- It is best viewed as an automated sanitizing and drying appliance, not a substitute for washing.
Momcozy BS01 Specifications and What’s Included
The BS01 is Momcozy’s three-layer sterilizer and dryer, not its automatic bottle washer. Official technical documentation identifies the model as BS01 and lists steam sterilization, drying, automatic combined operation, and storage functions.
| Specification | Momcozy BS01 |
|---|---|
| Product type | Steam sterilizer and hot-air dryer |
| Design | Three-layer removable arrangement |
| Bottle capacity | 6 larger bottles or up to 12 smaller bottles |
| Standard steam cycle | 9 minutes |
| Bottle drying | 28-minute default; adjustable 10–60 minutes |
| Combined bottle cycle | 37-minute default |
| Pump-parts combined cycle | 44-minute default |
| Storage mode | Up to 24 hours |
| Air filter | H13 HEPA |
| Water fill | 160 mL maximum |
| Device dimensions | Approx. 8.86 W × 11 D × 15.75 H inches |
| Rated power | 800 W |
| US voltage | 120V/60Hz |
These are published specifications, not measurements from an independent laboratory. The manufacturer’s support specifications and marketing material show slightly different overall dimensions, so allow extra room around the unit rather than relying on a tight fit.
What’s in the box: Momcozy lists one top lid, one bottle chamber, one base, two breast pump parts racks, one upper tray, one lower tray, and a user manual. The technical specifications also identify a HEPA filter. Confirm the included filter and any replacement accessories with the seller before purchasing.
Who Should Buy the Momcozy BS01?
The Momcozy BS01 makes the most sense when feeding equipment is washed frequently and needs to be dried and sanitized in batches. Parents who pump breast milk several times daily may get more use from its separate pump-part arrangement than occasional bottle users.
Who Will Benefit Most?
- Exclusive pumpers: Dedicated pump-part holders help organize cleaned accessories.
- Families using several bottles daily: Batch processing can reduce repeated trips to the kitchen.
- Caregivers who dislike air-drying clutter: The built-in dryer reduces reliance on countertop drying racks.
- Parents who want protected storage: The 24-hour mode allows cleaned and dried items to remain inside the appliance.
Who Should Skip It?
- Anyone expecting a machine that scrubs bottles or removes dried-on milk.
- Households with limited vertical clearance beneath cabinets.
- Users whose existing dishwasher already meets their cleaning and sanitizing needs.
- People who only use one or two bottles occasionally and do not need a separate dryer.
Momcozy Sterilizer and Dryer Pros and Cons
The BS01’s main strengths are its flexible racks, quick steam stage, and adjustable drying. Its biggest limitations are the separate washing requirement, reduced capacity for larger items, and routine maintenance.
Pros
- Three-tier layout separates bottles, nipples, and pump parts.
- Nine-minute steam stage before optional drying.
- Adjustable drying from 10 to 60 minutes.
- Storage cycle helps keep dry items protected for up to 24 hours.
Cons
- Does not wash bottles or remove milk residue.
- Full-size bottles reduce practical capacity.
- Requires water measuring, cleaning, and descaling.
- HEPA replacement interval is not clearly published.
How Does the Momcozy Sterilizer and Dryer Work?
The Momcozy Sterilizer and Dryer uses high-temperature steam to sanitize already-cleaned feeding equipment. It then uses hot air to dry the items. You can select sterilization, drying, or an automatic combined cycle.
The machine also provides separate modes for bottles and breast pump accessories. Momcozy states that the steam stage eliminates 99.9% of germs in 9 minutes. That is a manufacturer’s performance claim, not a result independently measured for this review.
Steam Sterilization
You add water to the base, load the cleaned items, and start the steam function. The heating element turns water into steam, which reaches exposed surfaces of compatible items.
Momcozy lists a 9-minute sterilization cycle. Bottles should be disassembled and arranged so steam can circulate rather than being blocked by tightly packed parts.
Automatic Drying and Controls
After sterilization, the BS01 can move into its drying stage. Its electronic controls include a rotating knob, digital display, and a Confirm/Pause button.
The unit also includes automatic shutoff and a memory feature, according to Momcozy. These reduce repeated setup, but you should still follow the appliance’s heat and electrical safety instructions.
Why Cleaning First Matters
Steam sanitizing does not remove dried formula, breast milk residue, or grease. The CDC’s infant feeding hygiene guidance explains that bottles must be washed before sanitizing.
That means the BS01 saves time on the sanitizing and drying stages, but the washing step remains your responsibility.
How Many Bottles Does It Hold?
The Momcozy BS01 can hold approximately 6 to 12 bottles, depending on bottle height, width, and how the trays are arranged. The upper number applies to smaller bottles, while larger feeding bottles generally require more space.
Momcozy’s detailed specifications identify compatibility with bottles up to 82 mm in diameter and 180 mm in height. Removable racks provide extra flexibility for accessories, but a crowded load can interfere with steam exposure and drying.
| Item type | Capacity or fit | Practical note |
|---|---|---|
| Small 2–4 oz bottles | 6–12 | Best chance of reaching maximum capacity |
| Larger 6–11 oz bottles | 6 | Allow space around each bottle |
| Mixed bottles and parts | Varies | Use the removable trays |
| Breast pump accessories | Varies | Two dedicated racks are included |
| Pacifiers and nipples | Multiple small items | Check steam compatibility before loading |
Practical buying tip: Measure your tallest bottle and widest pump component before ordering. Some bottles may fit only after rearranging or removing a tray.
How Fast Does It Dry?
The Momcozy BS01 provides selectable drying cycles from 10 to 60 minutes. Its standard bottle drying setting is 28 minutes, while the combined bottle sterilize-and-dry program defaults to 37 minutes.
For breast pump accessories, Momcozy lists a 35-minute default drying stage and a 44-minute combined program. These are programmed cycle times, not independent guarantees that every possible load will be completely dry.
Can It Dry a Full Load?
The dryer is intended to remove moisture from cleaned bottles and accessories. However, tight spacing, deep recesses, and trapped water may leave droplets after a short cycle.
Momcozy’s troubleshooting instructions recommend repositioning items so water cannot collect and increasing the drying time when necessary. This is especially relevant for complex pump components.
Does It Save Time Compared With Air-Drying?
Automated drying can reduce the amount of time feeding equipment occupies a separate drying rack. It also eliminates the need to wipe each item by hand.
The benefit is most noticeable with repeated daily loads. For a household that uses very few bottles, the time savings may be less meaningful.
How Safe Is the Sterile Storage Feature?
Momcozy says the BS01 can maintain a protected storage environment for up to 24 hours after the drying or automatic cycle. The storage program runs a short drying period each hour to help manage moisture inside the chamber.
Specifically, the manufacturer’s operating description calls for 5 minutes of drying after approximately 55 minutes of inactivity. The feature is convenient for preparing clean bottles ahead of feeding sessions.
Does the Storage Mode Guarantee Sterility?
No home appliance should be treated as a guarantee that opened or handled items remain germ-free. The manufacturer’s storage claim assumes the system is used correctly and its contents remain protected.
Opening the lid, handling parts with unwashed hands, or introducing dirty items can compromise cleanliness. Store completely dry items with clean hands and keep them protected until use.
Safety note: For babies younger than 2 months, babies born prematurely, or infants with weakened immune systems, CDC guidance places particular importance on daily sanitizing. Ask your pediatrician about any special feeding equipment precautions your baby needs.
Best Uses for the Momcozy BS01
The BS01 works best as part of an established bottle-washing routine. Its separate modes and adjustable racks make it more flexible than a basic steam-only sterilizer.
Daily Bottle Feeding
For families preparing several bottles daily, the combined steam and drying program helps keep a rotating supply of clean bottles ready. The covered storage option is useful when bottles are not needed immediately.
Breast Pump Parts
Breast pump components often have several small parts that need careful cleaning. The BS01 includes two dedicated racks and a separate pump-part operating mode.
Confirm that each pump accessory is approved for steam sanitizing. Some valves, tubing, electronic parts, and specialized components require different care.
Pacifiers and Small Feeding Accessories
Compatible pacifiers, nipples, and teethers can be arranged in the trays. They should be washed first and must be able to tolerate steam heat.
Do not assume that battery-powered toys, glued components, or every teether material is suitable for this machine.
How to Use and Maintain the Momcozy BS01
Using the BS01 is straightforward once you understand its controls. The key is to prepare clean equipment, use the correct amount of water, and avoid overloading the trays.
How to Sterilize and Dry Bottles
- Wash and rinse everything. Disassemble bottles and clean away all milk residue before loading the machine.
- Position the appliance safely. Use a flat, heat-resistant surface away from children and overhead cabinets.
- Add water. Fill the heating base to the indicated maximum of 160 mL without exceeding the mark. Distilled water can help reduce scale.
- Arrange the equipment. Place bottles opening-down and use the racks for smaller parts. Avoid tightly packing items together.
- Select the correct mode. Choose Common/Bottle Mode or Breast Pump Parts Mode, then select Sterilization, Drying, or Auto.
- Start the cycle. Confirm the selection and allow the machine to complete its program.
- Wait before opening. Hot steam can escape when the lid is lifted. Allow the items and unit to cool before handling.
- Store safely. Wash your hands before removing fully dried items or use the protected storage option as directed.
How to Clean the Heating Plate
Minerals in tap water can leave deposits on the heating surface. This buildup may affect the appliance over time, so regular cleaning is part of ownership.
- Unplug the machine and let it cool completely.
- Remove any remaining water and wipe loose residue with a soft cloth.
- For mineral deposits, Momcozy recommends using approximately 60 mL of a 50/50 water-and-vinegar solution on the heating plate.
- Allow the solution to sit for around 30 minutes, then remove it and wipe the surface clean as directed.
- Clean the removable parts according to the manufacturer’s instructions and dry them before reassembly.
Never immerse the electrical base or power cord in water. Avoid abrasive pads, steel wool, and sharp tools on the heating plate.
Common Problems and Simple Fixes
| Problem | What to check |
|---|---|
| Machine will not start | Power connection, On/Off button, and selected function |
| Bottles remain damp | Loading arrangement, trapped water, and drying duration |
| White deposits on plate | Mineral buildup; descale according to Momcozy guidance |
| Parts do not fit | Bottle dimensions and removable tray placement |
What Do Momcozy BS01 Owners Report?
Customer feedback on Momcozy’s product page generally highlights convenience, drying performance, and the flexible three-tier layout. These are owner-reported experiences, not results from our own hands-on testing.
What Owners Like
- Batch capacity: Owners appreciate loading several bottles and accessories together instead of processing small batches.
- Less manual handling: The dryer helps avoid leaving bottles spread across a countertop.
- Pumping convenience: Some parents who pump frequently value the ability to sanitize multiple pump parts.
- Protected storage: Users appreciate leaving clean items inside until they are needed.
Complaints and Limitations to Consider
- Tray arrangement: Taller bottles may require rearranging the removable layers.
- Controls: Some reviews describe a learning curve with the power button and selection process.
- Mineral deposits: Regular cleaning is necessary, particularly with hard water.
- Long-term reliability: Individual reports describe occasional malfunction or unexpected shutdown, although these reports do not establish a general failure rate.
Review trends can change over time. Check the most recent detailed buyer feedback and warranty terms before ordering, especially if you plan to use the appliance several times a day.
Momcozy BS01 vs. Other Bottle Sterilizers
The Momcozy BS01 is not the only option for steam sanitizing and automated drying. Baby Brezza, Dr. Brown’s, and Philips Avent offer alternatives with different bottle capacities and storage features.
| Model | Published capacity | Standout feature | Consider if |
|---|---|---|---|
| Momcozy BS01 | 6–12, depending on size | Three layers and dedicated pump-part mode | You use mixed bottles and pump accessories |
| Baby Brezza Sterilizer Dryer Advanced | Up to 8 bottles | 48-hour protected storage claim | Longer closed-lid storage matters |
| Dr. Brown’s All-In-One Sterilizer & Dryer | 8 narrow, 6 wide-neck, or 4 silicone bottles | Capacity specified by bottle type | You use Dr. Brown’s bottle systems |
| Philips Avent Premium SCF293/00 | Up to 6 bottles | 40-minute combined cycle | You prefer a simple, established bottle system |
Baby Brezza Sterilizer Dryer Advanced
Baby Brezza’s advanced model is worth comparing if longer protected storage matters to you. Its published specifications include capacity for eight bottles and a claim of up to 48 hours of storage when the lid remains closed.
It also offers a 30-minute hot-air drying program. The choice largely comes down to your bottle sizes, accessory load, and storage preferences.
Dr. Brown’s All-In-One Sterilizer & Dryer
Dr. Brown’s lists separate capacities for narrow, wide-neck, and silicone bottles. This makes its specifications easier to compare if you already use one particular bottle design.
It is a reasonable alternative for households that want a familiar bottle-care system with automatic steam sanitizing and drying.
Philips Avent Premium SCF293/00
The Philips Avent Premium combines steam sterilization and filtered-air drying in a published 40-minute cycle. It is designed to hold up to six bottles plus suitable accessories.
Choose between it and the Momcozy based on actual bottle fit, desired rack flexibility, and how often you sanitize breast pump components.
Is the Momcozy Sterilizer and Dryer Worth Buying?
Yes, for families who regularly use several bottles or breast pump parts, the Momcozy BS01 can be worth buying. Its main value is convenience: steam sanitizing, drying, and protected storage are combined in one appliance.
It makes a stronger case for itself if you pump frequently, use multiple bottles throughout the day, or want to avoid leaving washed items on a drying rack. The dedicated racks are especially relevant for a mixed collection of pump and feeding accessories.
However, the BS01 is less compelling when you only wash a few bottles, already have an effective dishwasher sanitizing routine, or need automatic washing. The ongoing need to descale the heating plate is another factor to consider.
Value Checklist
- Will you use the sterilizer most days?
- Do your bottles and pump parts fit comfortably?
- Will automatic drying solve an existing problem?
- Do you have suitable counter space and a compatible power outlet?
- Are you willing to clean the heating plate and maintain the air filter?
If most answers are yes, the BS01 is a sensible appliance to consider. If not, a simpler sterilizing method may be enough.

Frequently Asked Questions
Does It Have a HEPA Filter Replacement Schedule?
The Momcozy BS01 includes an H13 HEPA air filter, but an exact replacement interval was not established from the official documentation reviewed. Follow the instructions supplied with your unit and contact Momcozy for the current maintenance schedule. Do not assume the filter lasts indefinitely, especially with frequent drying cycles.
Can It Sterilize Pacifiers and Teething Toys Too?
Yes, the Momcozy BS01 can sanitize suitable pacifiers, teethers, and other small accessories using steam. However, every item must be approved by its manufacturer for high-temperature steam treatment. Wash items first, arrange them to allow steam contact, and avoid electronic toys or materials that may deform with heat.
Is There a Dedicated Holder for Pump Parts?
Yes, Momcozy lists two breast pump parts racks in the BS01 package. The machine also has a separate operating mode for pump accessories. These features help arrange compatible flanges and smaller parts during sanitizing and drying, but you should check each pump manufacturer’s care instructions before exposing components to steam.
Does It Remember My Last Drying Settings?
Yes, Momcozy advertises a memory feature for the BS01. This can reduce repeated setup when you use similar settings regularly. The machine also provides selectable drying times and separate bottle and pump modes. Check the current user manual for how stored settings behave after switching modes or disconnecting power.
Will It Shut Off Automatically if Forgotten?
Yes, the BS01 includes automatic shutoff as one of its advertised features. This is useful when a normal sterilizing or drying program finishes, but it does not replace safe operation. Keep the appliance on a stable surface, away from children, and follow the instructions for unplugging and cleaning it.
Does the Momcozy BS01 Wash Baby Bottles?
No, the BS01 does not wash bottles or remove milk residue. You must thoroughly clean and rinse all feeding items before placing them in the sterilizer. Its functions are steam sanitizing, drying, and storage. If you need automated washing, compare a dedicated bottle washer rather than this model.
How Much Water Does the Momcozy BS01 Need?
Momcozy’s BS01 setup instructions specify filling the heating base to the 160 mL maximum line for steam operation. Never overfill the unit. Distilled water can reduce mineral buildup, although the manufacturer also allows other suitable water sources. Drying-only operation does not require adding water to produce steam.
How Do You Remove Mineral Buildup From the BS01?
Unplug the sterilizer and allow the heating plate to cool completely. Momcozy recommends a diluted vinegar solution for mineral deposits, followed by careful cleaning of the plate. Avoid steel wool, abrasive tools, and immersion of the electrical base. Regular maintenance helps prevent deposits from interfering with normal operation.
Conclusion: Final Momcozy BS01 Verdict
The Momcozy Sterilizer and Dryer BS01 offers a useful combination of steam sanitizing, adjustable drying, and short-term protected storage. Its three-layer arrangement and dedicated pump-part racks make it especially appealing to families with a demanding feeding schedule.
Its limitations are clear: you must wash items before loading, larger bottles reduce capacity, and the machine requires maintenance. For regular bottle and pumping use, it is a solid option. For occasional sanitizing, a simpler solution may be more economical.
