Meet our first special edition NanoFoamer Lithium! Beautifully crafted in solid white and featuring and all-white minimalist box, this product is the ultimate gift for any coffee lover in 2023. Available while supplies last.
Foam Like a Pro
With its cutting-edge technology and sleek design, the Nanofoamer revolutionizes how you enjoy your favorite coffee drinks at home. Say goodbye to clumpy foam and hello to a smooth, creamy texture like never before!
Crafted with precision, the Nanofoamer boasts an innovative foaming mechanism that creates microscopic bubbles called microfoam, resulting in a vibrant and luxurious texture. So whether you prefer cappuccinos, lattes, or matcha lattes, this remarkable device delivers café-quality microfoam right in the comfort of your home.
The Nanofoamer is compatible with dairy milk and excels with milk alternatives, catering to various dietary preferences. Cleaning is a breeze, too. Two models are available, the battery-powered V2 and the USB-C rechargeable Lithium model.
The NanoFoamers make microfoam ideal for pouring latte art, so we include a latte art masterclass with every purchase.
Never settle for ordinary foam—indulge in extraordinary microfoam with the NanoFoamer.
Your perfect coffee, made just the way you love it.
...made in 3 easy steps
Pick a NanoScreen to suit your microfoam tastes: Superfine, fine, or ordinary foam.
Churn your warm milk for 20+ seconds. Start in the middle to add air to the foam, then move to the side for a perfectly consistent blend.
Pour your premium microfoamed milk over your coffee. Feeling artistic? Draw a heart, rosetta, or something more abstract!
Our new NanoScreens now clip into the impeller rather than press-fit. This ensures they stay nice and flat.
We’ve upgraded to a material that’s even more food-safe and long-lasting. Your impeller will have a longer life, even with constant use.
You can now replace the impeller in the event of accidental damage.
Stainless Steel housing
Our motor housing is now made of real stamped stainless steel.
On/Off Digital Switch
By popular demand, our new switch is an ultra-light touch on/off switch.
New Rechargeable Model
Powerful, multi-touch two-speed option using rechargeable 3.7v Li-ion battery.
Re-built every aspect of the NanoFoamer to provide a better experience.
Improved internal build quality with tighter tolerances inside the motor.
New Battery Housing
Sturdy, tight fitting battery compartment to dampen vibrations.
Enjoy superfine microfoam at home
With NanoFoamer, your milk has bubbles so fine they’re invisible. Your milk pours with the consistency of liquid velvet, not frothy but seductively smooth.
Superfine Microfoam milk in Seconds
Cafe-quality microfoamed milk in the comfort of your own home! Enjoy your own barista-style cappuccino every day.
“For someone who is on the go, making a quick barista quality coffee has always been a challenge. Now I am able to create silky smooth lattes in the comfort of my own home in an instant. ”
The Smoothest Velvet Textured Milk
Savor coffees that taste better, look better, and have a texture that’s truly irresistible.
“The Subminimal NanoFoamer makes the best microfoam of any non-steam-wand solution I know of. And as most who have tried other frothing wands would know, they usually don't produce proper microfoam at all. The NanoFoamer does a brilliant job.”
Keep your NanoFoamer handily by your coffee station on our sturdy wall mount.
Our NanoFoamers are waterproof so you can quickly rinse them clean after use.

Love the added power it has and bonus is no more wasted batteries! It charges quickly. And doesn’t need to be charged that often. I use it several times daily

Honestly makes milk as good as you can get it. Took a while to figure out, but I kept getting too much foam, so couldn't make late art, ended up getting a different brand of milk and moving from semi-skimmed to full fat and the difference is incredible. Both make amazingly delicious milk texture, but the full fat milk is better for latte art

The Nano foamer has been a game changer in my households frothing business.
Prior to the Nano foamer I was using a typical handheld battery run milk frother... safe to say I will not be using that one ever again.

The best handheld foamer ever !!!
Both units share the same design and components. The differences are:
* The V2 is powered by two AA batteries (not included) and has a top speed of about 3,000 RPM
* The Lithium is rechargeable via USB-C, powered by a 3.7V built-in Lithium-Ion battery, and has two-speed option: 4,000 RPM and 3,000 RPM when fully charged.
We offer a one-year warranty against manufacturer defects.
We replace defective products at no cost or provide replacement components if there is minor damage.
If you believe you have an issue with your product, please send a quick video to hello @ subminimal.com so we can troubleshoot.
Yes, so long as it is a good-quality USB power supply that follows USB specifications.
*Why:* USB-C power supplies (chargers) must only provide 5V / 2A by default. They can only provide more power, fast charging, and power delivery if they communicate with the device.
In the case of the NanoFoamer Lithium, no such communication will occur, so all chargers should only provide 5V 2A for normal-speed charging.
The Lithium-Ion battery cannot be changed. It only needs charging once every few weeks and lasts hundreds of full charge cycles, giving it a very long life.
Introducing V2 and Lithium
Make perfect microfoamed milk in a matter of seconds.
Completely rebuilt and re-engineered. Features 10+ major
improvements and a rechargeable option.
- Click-On NanoScreens Our new NanoScreens ditch the pressure fit system for a satisfying snap-fit, ensuring a far stronger hold on the impeller while simultaneously preventing buckling over time.
- Replaceable Impeller Replace the all-important impeller as anytime in the event your NanoFoamer takes an unfortunate tumble.
- Upgraded Impeller Material The impeller material is upgraded to Polycarbonate (still BPA free & FDA certified), making it more resistant to the stresses of the fast rotations in hot liquids.
- Improved Waterproofing Overall better seals on the closures and shaft.
- Better Motor The upgraded motor is more powerful, built to tighter tolerances, and more reliable.
- Stainless Steel Housing The motor housing is now made of real brushed stainless steel for a far more premium experience.
- More Stable Shaft Tighter tolerances deep inside the motor translate directly onto the shaft's stability. Spinning dead center is key to spinning fast and reducing vibrations.
- On/Off Digital Switch The upgraded button is a feather-light on/off switch, allowing you to focus on the foam while holding the NanoFoamer as lightly as a pencil.
- Safety PCB Auto shut off after ninety seconds to prevent the ultra-fast motor from overheating the housing.
- New Battery Housing The internal design is as beautiful as the outside, with the batteries fitting directly into the handle and connecting with premium spring-loaded contacts.
- Reduced Vibrations The new internal design is built to much tighter tolerances, keeping everything snug to reduce all vibrations from the handle.
- All New Engineering Better internal engineering with sonic welded components instead of snap-fitted parts.
- All of the above The NanoFoamer lithium shares all of the above improvements with the addition of the below upgrades.
- Powerful Li-ion battery A powerful 3.7V 1200Mah lithium-ion battery gives this product superpowers up to 14k RPM and very high torque.
- Dual-speed This NanoFoamer is so powerful, that we had to slow it down, so we built it with a multi-touch switch for selecting one of two speeds.
- Battery Level Indicator Four LEDs quickly show you when you should consider recharging.
- USB Type C USB-C is the connector of choice for all the best electronics on the market today, so you can recharge your NanoFoamer with any USB charger you already own.
