I’ve had a few of these mini blowers but this one is my new favorite.
The controls are very ergonomic and the slider allows for full linear control to easily set the desired speed.
At full charge, this clocked a wind speed of just over 30 mph from 12 inches away. It’s not the most powerful blower at this price point, but it’s ergonomics and the fact that it’s also a mini vacuum makes this the best option, for me anyway.

Vacuum mode is enabled by clicking the power button 3 times. The vacuum attachment traps the debris without letting it enter and damage the impeller. With the brush attached, I honestly can’t think of a better way to clean my keyboard, car vents, or any of those other small areas that rarely ever warrant getting out a full size vacuum.

This little thing is very powerful. It is a great replacement for buying canned air all the time for dusting and cleaning out the computer towers. It is kind of noisy, but no more than canned air already is. I like that it has attachments and a bag to hold them.

There is a problem that isn't bad but it is annoying. When the -/+ slider is all the way to - it doesnt blow any air even when turned on. So, we thought we got a dud at first since the slider was all the way down when we first got it. So if you have trouble turning it on make sure the slider is up.

Overall, this is very easy to use and removes dust really well.

If you're looking for a high-quality air duster, the K&F Concept Blower & Suction 2-in-1 Compressed Air Duster is an excellent option. It’s a powerful and eco-friendly replacement for traditional canned air. The built-in motor is strong and offers multiple speed settings, allowing you to effectively clean dust and debris from a variety of surfaces—not just your computer or keyboard.

One standout feature is its dual function: it can blow air to remove dust and also switch to suction mode with the included suction cup accessory. This 2-in-1 design adds versatility, making it useful for both cleaning and light vacuuming tasks.

The device is USB-C rechargeable, making it convenient for travel. A USB-C charging cable is included (note: a power block is not), and a travel pouch is provided to neatly store the duster and all its accessories. It also comes with five microfiber cleaning cloths, which are perfect for cleaning delicate surfaces like phone or computer screens.

Overall, this air duster is a great addition to your cleaning toolkit. It’s powerful, portable, and versatile—ideal for cleaning electronics, home surfaces, or even car interiors.

Great little air gun that also doubles as a small vacuum. It comes with a nice storage bags, microfiber cleaning cloths, and several attachments to get the job done. It’s stronger then I expected!

So, I ordered this little device to replace a similar small vacuum I have that really hasn't worked that well. I saw this and decided I needed to give it a try. I will be honest and say that when I first opened the package this device is smaller than the other version I have and I was immediately disappointed and thought I had made a mistake. However, I decided to go ahead and give it a full charge and see what happens then. I don't know what to say other than I was blown away. This device has more power than I could have ever imagined and I tried to show it with a video. It is extremely powerful. I haven't tried it in a real world application but if the amount of power this things displays is any indication then it's going to work just fine.

The K&F Concept 2-in-1 Compressed Air Duster is a surprisingly powerful little device that feels high-quality and fits perfectly in my hand for easy pointing and cleaning. Despite its compact size, it blasts dust from my keyboard, laptop, and even car seats with impressive force, and the variety of attachments makes it versatile for tackling crevices or inflating things like air mattresses. I love the USB charging and clear charge indicator, which add convenience, and the included cleaning cloths and storage bag keep everything tidy. This duster’s uses seem endless—great for the office, garage, or kitchen!

Pros:
- Compact, ergonomic design feels sturdy and easy to use
- Powerful 150,000 RPM motor for its size
- Versatile attachments for multiple cleaning tasks
- USB charging with clear indicator, plus handy storage bag

Cons:
- Can get a bit loud at max speed
- Takes a few tries to master switching between blowing and suction modes

I use compressed air cans frequently to clean electronic parts and blow off dead bugs on my bug zappers. The problem is that these don't last long, and they are expensive.

I saw this compressed air duster by K&F Concepts that claims it can replace compressed air cans. I had to give it a try.

The air duster arrived very well packaged, like a high-end piece of electronic equipment, and comes with a lot of stuff.

The first thing I noticed with this duster is how small it is. It is tiny, and it feels very solid and well-made.

It comes with multiple different nozzles, a carrying bag, cleaning cloths, a vacuum attachment, a charging cable, and a user manual. There is also an inflator nozzle you can use to inflate your inflatable toys.

What makes this air duster unique is that it is also a portable vacuum, so you can not only blow off dust, but you can also vacuum.

The blower has a slider on it that adjusts the speeds from low to high. You can also turn on an LED that lights up what you're blowing.

I found this duster to be powerful enough to easily replace compressed air cans.

I have used this duster for cleaning my bug zapper, cleaning electronic equipment, and even cleaning the dust off the dashboard and instrument cluster on my vehicles. I have even tried this to help start a campfire, and it worked amazingly well.

The vacuum is perfect for vacuuming very small areas like keyboards, but it is not powerful enough to replace a dedicated portable vacuum, but I do not think that was the intention of the manufacturer.

The duster is small and rechargeable, so it can easily be taken anywhere.

I am very happy with this portable duster and vacuum.

It works great, comes with lots of attachments, and is super compact.

I do recommend it.

I ordered the K&F Concept 2-in-1 electric air blower and it performs well. The brushless motor runs at 150,000 RPM, achieving a maximum wind speed of 54 m/s. It has a built-in 5000 mAh battery, which can be recharged via a USB-C cable. The device is operated using only a button and a slide switch. The button toggles between different functions: a long press turns the blower on/off, a single short press turns the light on/off, and three short presses turn the vacuum on/off. The slide switch allows you to adjust the blowing and vacuuming power. Various attachments for blowing and vacuuming are included.
























... The package includes:

-Air blower-4 nozzles/brushes
-1 vacuum attachment
-1 vacuum attachment with 3 replacement filters
-Storage bag
-5 dust cloths-USB-A to USB-C charging cable

I haven't had it long enough to use it, but the device makes a good impression.

I like the air blower and can recommend it.

PROS:
- Power;
- Accessories;
- Size.
CONS:
Nothing to report.

Considerations and evaluation:

I have another similar item. And I was impressed with the motor's capabilities.
This K&F Concept is truly an item that can be used for excellent purposes with very respectable performance.
The motor's power is remarkable, the "blow" power rivals (not entirely, obviously)
a combustion-engine compressor, and it easily solves any cleaning problem in the home. Dust, debris, and even large parts can be moved from hard-to-reach areas, and obviously dust and other items can be easily removed.
I haven't evaluated the suction head or the accessories, but I honestly don't care because this item's function is to "blow," and it does that very well. Moreover, it's very compact. The LED light adds value to the item's features. It's worth 5 stars for me.

A cordless handheld blower was delivered, along with a generous range of accessories.

Various nozzles are included to concentrate the airflow. There's also a nozzle with a brush for cleaning.

An attachment for vacuuming dirt is also included.

The blower itself is very compact and fits comfortably in the hand.

However, it can be a bit noisy at times. This is due to the high speed and the accelerated airflow.

The blower is switched on using a button on the bottom. Four white LEDs then illuminate to indicate the battery level.

The blower can then be switched on and the speed adjusted using a slider on the side.

If you press the power button a second time after switching it on, a white LED in the air outlet illuminates, directly lighting the work area.

If you press the power button three times after switching it on, the blower runs in reverse, drawing air in from the front. This allows you to vacuum up dirt.

However, the filters are just simple foam circles, meaning they only filter out coarse material.

The performance is excellent; I can't comment on the battery capacity yet.

Highly recommended!
