Autowit Fresh 2 Design
Autowit Fresh 2 has a premium design. It looks like a water bottle or a small speaker that is made of high-quality plastic and aluminum, which provides a unique design.
The Autowit Fresh 2 is such a small device, made for car usage, which indicates that you won’t have any trouble fitting it to your car cup-holder.
Touch Buttons
There is only one button to control the Autowit Fresh 2 air purifier, but with that button, you can control four adjustable modes, Auto Mode, Silent Mode, Medium Mode, and Strong Mode.
One push on the power button will start the air purifier in auto mode. You can confirm that Auto Mode is running by blinking LED light. If you push the power button the second time, you will enter Silent Mode.
Silent Mode is the quiet mode, and you can see that you are in silent mode if one-third of LED lights are on. On the next push, you are switching Fresh 2 to Medium Mode, and two-thirds of the LED light is on.
Strong Mode is the most effective mode on this Autowit model, and it will purify the air at the fastest speed. However, this mode is the loudest as well. When the strong mode is on, all LED lights are turned on. If you click the power button again, you will switch back to Auto Mode, and the circle continues. It is a pretty simple control that is very effective to use.
To control the Fresh 2 humidifier feature there is a drop button above the power button. When the humidifier is on, you will see the blue light on the LED, and then the device will start to release water vapor. Once you turn the humidifier on, it will work for 15 minutes, after which it will work in cycles of three minutes pause and one minute work.
Distilled water is not required, you can use regular water and a humidifier will work just fine. Under no circumstances should you add essential oils. Essential oils may damage the humidifier.

Autowit Fresh 2 air purifier and humidifier in one is small (8.5 x 3.1 x 3.1 inches) and easy to move from car to car, or even from car to home and vice versa. It’s made from high-quality plastic and aluminum, and when you hold it, you will notice that it is heavier (15.5 ounces) than it looks.

Review of Autowit Fresh 2 Features
Removes 99% Airborne Particles
With a combination of a powerful motor and HEPA filter, Autowit Fresh 2 air purifier will suck large amounts of air in a small period, and remove 99% of particles from the air. Dust, smoke, germs, pet dander, bad smell, and other allergy triggers can be easily removed with Fresh 2 air purifier.
3 Stage Filtration
Autowit Fresh 2 has three stages of filtration that include a nanosilver filter, a HEPA filter, and a high-quality charcoal filter.
The first one in the order of sucking air is the nanosilver filter, which is actually a pre-filter that is used to remove all the big particles that can be caught without a HEPA filter.
HEPA fold filter is the second line of defense, which removes almost everything from the air. The only thing that goes through the HEPA fold filter is smoke, gas, and other bad smells.
The third and last line of defense is a high-quality charcoal filter. The charcoal filter is used to remove bad odors, chemicals, gases, and other unwanted smoke from the air.
Four Adjustable Airflow Modes
Usually, air purifiers have three speeds, low, medium, and high, but Autowit Fresh 2 has four, which means more choices that will surely cover all your needs.
Thanks to the robust design and almost noise proof construction, Autowit Fresh 2 is not noisy. You can drive in silence with Fresh 2 without any trouble, especially if you set it to low speed. At such mode, you won’t even know that the air purifier is cleaning the air in the car.
Smart Auto-Detection Sensor and Visible Display
Autowit Fresh 2 is a premium air purifier with some advanced functions. Of course, such an advanced high-tech product will have smart sensors. In my opinion, having a real-time indicator of air quality is a good way for being sure that the air purifier actually works. I can say that this smart sensor in Autowit Fresh 2 is a price worth feature.
There are three levels of pollution that Fresh 2 detects. The green light means that air quality is excellent. If you notice the green light is lighting for some time, I suggest turning off the air purifier and let it relax a bit. You will know that the air quality is well when the air purifier emits green light.
A yellow light means that the air is ok, acceptable, but not the best. It is a wise choice to let the Fresh 2 on now and prevent the air from going to the last level, which will emit red light.
When you see the red light, you must immediately turn the air purifier to maximum fan speed because the air in the car is poor. Trust me; you don’t want to breathe poor quality air. Poor quality air is filled with allergens, dust, pollen, or other unwanted airborne particles that can harm your respiratory system. Always make sure that the light on the air purifier is green.
Air Humidification Done with Built-In Water Tank
Air humidification with Autowit Fresh 2 combo is very simple. You fill the water in the built-in water tank and let the air humidifier do the job. You can watch how the fresh humidifier air is coming out on the top of the device.
Autowit Fresh 2 uses ultrasonic sounds to change water into vapor. There is no heating process, and you don’t need to wait for the device to heat up. Usually, when technology heats up, it also emits some unwanted components like ozone. However, Autowit is not heating water; it uses advanced technology to release cold vapor in the air.
The human ear can not hear these ultrasonic sounds. We humans can not hear this sound, which means that the sound that this humidifier emits will not bother you.
Low Energy Consumption and Low Maintenance Costs
Low maintenance costs are one of the benefits you will get if you decide to buy Autowit Fresh 2. The only thing that needs to be replaced in the Fresh 2 air purifier is a filter, which will work for up to 4 months if you use the air purifier properly. There are no other costs involved with this product. You won’t even need to clean anything inside the air purifier.
Another good thing about the Autowit air purifier is that you can turn it on with a USB cable. This device can use different power supplies to work. The most important thing is the power supplier has a USB port so you can plug-in the air purifier.
On the other hand, you can have a laptop and plug the air purifier in a USB port and have it charged while you play games or write an essay, and at the same time enjoy fresh and clean air coming out from the Autowit Fresh 2.
Mobile Device
Autowit Fresh 2, thanks to its small size and ability to plug it in various power sources, is one of the best mobile air purifiers you can buy. It is also one of the best air purifiers for the car. You can place it in a car bottle holder, and for a return, you will get fresh and clean air. Nowadays, each car has more than one bottle holder, so there will always be empty space for an Autowit Fresh 2.
This small but very powerful little device will purify the air in the car and make driving pleasant without trouble.
Warranty
Autowit gives a not-so-generous limited warranty of one year. Since the day you bought it, you can be safe that the air purifier will work as intended. If you have any questions, you can contact the Autowit company on their website, and get all the answers you need.
Autowit Fresh 2 Filters
The size of the Autowit Fresh 2 filter is small since the size of the whole device is small. However, that small filter can still remove 90% of PM 2.5 particles, as well as pollen, dust, smoke, odors, floccus, formaldehyde, and other particles.
As it uses a three-stage filtration system (composite nano filter, HEPA folded filter, and carbon filter), Fresh 2 can remove 99% of all airborne particles. The only problem with the filter is that it can get dirty too fast and need to be replaced every 3 to 4 months.

Noise Test
The noise of Autowit Fresh 2 depends on the speed you use, and there are Silent Mode, Auto Mode, and Strong Mode.
In silent mode, you will not hear it working. On auto mode, the device will automatically switch speed, and it could be noisier if running at a higher speed.
If you are a driver who likes to chat or listen to the radio while driving, you will not hear the Autowit Fresh 2 is working even if you let it run on Strong Mode.
I used the Autowit air purifier during the car ride to check if it’s going to disturb me while driving. The air purifier was on all the time, and I didn’t even notice that. It’s quiet enough and didn’t cause me any trouble during the ride. Additionally, I used special equipment for noise measuring, which uses dbA ratings. Results may vary from the official ones, and below is the table where you can see noise results.
| Speed | Value (dBA) |
|---|---|
| Speed 1 | 45.3 dBA |
| Speed 2 | 58.3 dBA |
| Speed 3 | 66.8 dBA |
Performance Tests
I wanted to compare how much the Autowit Fresh 2 will improve the air quality in different conditions. I used the air purifier in a car while somebody was/wasn’t smoking and during the morning/day/night ride. In the end, I used it during the longer/short rides and during different weather conditions. All the performance tests I did you can find below.
Testing in Everyday Drive
I tested Fresh 2 in everyday-driving in the morning, afternoon, and at night. I used a short drive as well as a long drive in different weather conditions.
In ordinary everyday driving, the air purifier managed to drop AQI from 130 to 19, and air quality was improved by 86%. These results are amazing if we consider the filter size and the airflow that the Fresh 2 air purifier makes.
| # | Starting Baseline | After 30min |
|---|---|---|
| PM 2.5 | 99 | 13.5 |
| PM 10 | 138.6 | 18.9 |
| Particles | 143571 | 19647 |
| AQI | 130 | 19 |
Testing in the Car with Smoker
I tested Autowit Fresh 2 in a car with a person who was smoking with all the windows shut and the air conditioner off. The Fresh 2 air purifier had real troubles with filtering the air when a person was smoking. The air quality indicator was flashing bad air all the time, and AQI was as high as it got, pointing to 999.
As soon as the person stopped smoking, the air purifier improved the air quality in only 4 minutes. In only 10 minutes AQI drops from 999 to 226. In just 16 minutes, AQI was pointing at safe air, and on display was number 49. Autowit Fresh 2 needed only 16 minutes to improve the air for 95%.
| # | Starting Baseline | After 16min |
|---|---|---|
| PM 2.5 | 999.9 | 34.8 |
| PM 10 | 999.9 | 48.7 |
| Particles | 1449999 | 50470 |
| AQI | 999 | 49 |
In my opinion, Autowit Fresh 2 is an excellent air purifier to use in a car, as well as it is not well for using it in rooms even the room size is below 86 sq. ft.
I suggest checking some other air purifiers instead of Fresh 2 for using it in an office or a small room. For example, Levoit LV-H126 is perfect for a small office, or even the GermGuardian AC4100 that will make excellent results in your room. I also did a review of the TaoTronics TT-AP001 that made outstanding results when testing it in smaller rooms.
FAQ on Autowit Fresh 2
How often should I replace the filter?
As it is pretty small, you should change the filter between 3 – 4 months.
How long can I use the air purifier per day?
It depends on the air quality, but I suggest using the Fresh 2 in Auto mode until the device goes green. After it goes green, use it for a few minutes more. Otherwise, if the air around you is too polluted, you should use the device on the third speed for a longer time.
Is the Fresh 2 chargeable?
No, it’s not chargeable. You power the air purifier by plugging into a USB charging port, and you can use various power suppliers like a phone, a laptop, a power bank, etc.
Is it good to use it while I’m smoking in the car?
Autowit Fresh 2 is not powerful enough to fight the smoke while somebody is smoking. As soon as the person stops smoking, the air purifier will purify the air in your car within 16 minutes. Therefore, I suggest opening the window while smoking and using the air purifier after, for additional air cleaning.
