AirFanta 3Pro review

If you like the idea of a Nukit Tempest but you worry about the process of building it yourself from scratch with multiple PC fans, parts and screws, then this device by AirFanta might be the perfect option for you.

The AirFanta 3Pro is a creation of Adam Wong, someone who is very active on social media platforms — you might recognize him by his handle: @Engineer_Wong. Wong started his journey developing air purifiers in 2022, right after China left the Covid Zero policy. His beginnings involved assembling Corsi-Rosenthal boxes for friends and family, powered by his engineering background. Over time, he started receiving CR box requests from the local Covid Cautious community. This led to him designing and developing a new kind of DIY box that could be assembled and disassembled easily.

As with all the air purifiers we tested, we paid for the AirFanta 3Pro with our own money to experience the entire customer journey, conduct various tests and write an honest (and unbiased) review. If you decide to buy an AirFanta 3Pro after clicking on a link from this review, you will be supporting our work, as we will get a small commission at no extra cost to you.

The pros and cons of the AirFanta 3Pro

A summary of our top-level findings after testing this air purifier following our methodology.

If you don’t want to read my full review, here are the six things we like about the AirFanta 3Pro and the three things we don’t.

The best feature: it fits inside a carry-on bag

This is the only high-CADR air purifier you can bring with you wherever you go.

Adam Wong designed the AirFanta 3Pro to be not only highly powered but also portable. You will not find any other air purifier with a CADR above 400 that you will be able to fit inside a large backpack or small suitcase.

Filtration technology

Four HEPA 11 filters (with the option of activated carbon) with an expected life of 6-12 months. Wong stated that they can last a full nine months before they need to be replaced.

Unlike actual DIY air purifier kits, you won’t be able to simply pick up some HVAC filters for your AirFanta 3Pro, so you will need to buy the official AirFanta filters. You can choose between HEPA 11 filters only or HEPA 11 with activated carbon. We have both because we wanted to test the performance of the 3Pro with and without activated carbon.

For those needing to tackle odors and gases, the best option is the carbon filter. It is a bonded filter (similar to those we see in Levoit devices) that combines a 15mm thick HEPA 11 filter with a 10mm layer of activated carbon.

Design and controls

The 3Pro is a small and light with a design inspired by the Corsi-Rosenthal box.

The AirFanta 3Pro is basically a box with a base at the bottom, one filter at each side and a fan array on top — much like the design of the Corsi-Rosenthal box.

The thing with the AirFanta 3Pro is that it is A LOT smaller than a CR box and that other PC fan kits using large HVAC filters:

Now, while this is not a DIY kit like the Nukit Tempest or the CleanAirKits Luggable XL-7, you still need to put the AirFanta 3Pro together, but it’s a lot easier to do compared to the Tempest and the Luggable.

As I mentioned briefly above, the AirFanta 3Pro has been designed to be cheap and portable: when you take it apart, you will be able to fit it neatly inside a standard carry-on bag. It even fits snuggly inside Gisele’s Osprey Proxima backpack:

In terms of controls, the AirFanta 3Pro comes with a 110-220v AC to 3-12v stepless DC power adapter which will allow you to control the speed of the fans and the noise output.

Something that I really appreciate about AirFanta and Adam Wong is how committed they are to keep improving their devices based on customer feedback.

A few days after we ordered our 3Pro, I saw a tweet from Wong in which he announced the introduction of a handy Velcro strap in response to an idea from @ParentMishmash:

Thanks to the advice from @ParentMishmash
I decide to add a piece of cable management Velcro in the 3Pro package from today.
It would help the installation.
Please note that the batches that already on the way to US and Canada don't contain this. pic.twitter.com/6hkFdoOhhJ

As mentioned at the top of this review, you can use this very same Velcro strip to strap the filters + fan array + base together once you have disassembled your 3Pro to ensure all parts fit nicely inside your suitcase or backpack. Simple yet effective!

Air cleaning performance

The AirFanta 3Pro cleared our test room in 17 minutes — it is nearly as fast at cleaning the air as the MUCH larger Smart Air Blast Mini.

I’ve been really keen to test the AirFanta 3Pro because there has been a lot of hype around it — especially after it was independently tested by Rob Wissmann and David Elfstrom. These are the results of their CADR tests:

• CADR: at 13V: 436 CFM
• CADR at 12V: 413 CFM 
• CADR at 9V: 328 CFM 
• CADR at 6V: 213 CFM 

I’m happy to report that the hype is completely warranted. Let me walk you through how the 3Pro performed in our tests.

According to our PurpleAir Zen sensor, the AirFanta 3Pro needed 17 minutes to achieve PM1 zero in our 728 cubic ft. test room running at top speed (12.6v). We estimate a PM1 CADR of 353 cfm, which would allow the 3Pro to provide five air changes per hour in rooms no larger than 529 sq. ft.

Swapping the filters for the HEPA + activated carbon option added three more minutes to the test, bringing the time to clean all traces of PM1 smoke pollutants to 20 minutes:

This matches the incredible CADR score tests performed by David Elfstrom and Rob Wiss, and compares quite favorably with other air much more expensive air purifiers.

As you can see in the table below, the AirFanta 3Pro is not only affordable but also incredibly fast at cleaning the air:

Our air cleaning performance test showed that at its highest fan speed (12.6v), the AirFanta 3Pro is as powerful as devices costing upwards of $450 and more effective at removing particles from the air than much more expensive air puriifers like the Dyson BP06.

Sound levels

In our testing, the sound levels of the 3Pro ranged from 36.1 dBA to 56.3 dBA. It is much quieter than the new Winix T810 (62.5 dBA) and the Coway AIrmega 200M (64.3 dBA)

The second most important thing to look at when choosing an air purifier is the amount of sound it generates. A device that is too loud is unlikely to be used regularly or, even worse, is likely to be switched off.

That is why we record (from 3 ft. away) the sound levels generated by every air purifier we test running at each fan speed in the same location (our basement). 

The AirFanta 3Pro comes with an AC-to-DC power adapter, which includes a dial for adjusting the voltage and the sound level generated by the air purifier. Here are the results at each fan speed we measured:

At top speed, the AirFanta 3Pro reaches 56.3 dBA, which is quieter than most mind-sized popular traditional air purifiers available on the market today:

However, you may be wondering how this compares to other devices, especially other PC fan-powered air purifiers. Check out our table below:

Compared to other PC fan devices from Nukit, CleanAirKits and NorthBox Systems, the AirFanta 3Pro is much louder at its highest fan speed. However, it’s still in line with the top-speed sound levels of the traditional retail HEPA devices we have tested. 

However, sound levels at top fan speeds are not as important as air cleaning performance at lower fan speeds.

That is why we always identify a fan speed where the air purifier generates less than 45 dBA of noise to assess its quiet performance. In the case of the AirFanta 3Pro, we repeated the particle removal test multiple times across different voltages:

My recommendation is to go for 6.54V for top performance at sub-45 dB noise levels. Running at this speed, the 3Pro generates 43.3 dB of noise while still being able to clean our test room in 28 minutes.

When we account for sound levels, we see the performance of the AirFanta 3Pro getting beat by the CleanAirKits Luggable XL-7, which managed to clean our test room in 23 minutes even when running at only 38.8 dBA. However, the Luggable XL-7 costs upwards of $200 (plus filters), so considering the low cost of the AirFanta 3Pro ($159.99 including filters), I am super impressed. 

What impresses me the most is how incredibly well the AirFanta 3Pro compares to the shop-bought HEPA air purifiers I have tested. At its top speed, it is faster and quieter than most of the devices we have reviewed here at HouseFresh.

Long-term running costs

Running an AirFanta 3Pro will cost you $165.76 per year, combining energy consumption costs ($47.76) and filter replacement costs ($118).

As always, I calculated the long-term costs associated with running your AirFanta 3Pro all day, every day at its top high speed for a full year — an unlikely scenario as you’ll probably want to have it running at a lower fan speed, but it’s a good baseline for running costs.

I started by using our energy meter to measure how much electricity the 3Pro uses at different voltages and, when running at top speed (12.6V), it pulled 43.23 watts.

This means that if you had to leave your 3Pro running 24/7 at top speed, it would cost $47.76 in energy costs for a year, using average U.S. energy rates as of July 7th, 2025.

Considering you need to replace the filter every six months and that the replacement costs $59 (HEPA only), you can expect to also spend $118 per year on filters.

When compared to other similar-performing air purifiers, the 3Pro has low energy consumption costs but it’s the OEM filter replacement costs that drive the yearly running costs up.

At 43.2 watts, the AirFanta 3Pro is more energy-efficient than many popular units, such as the Winix 5510 or the Levoit Vital 200S. However, compared with another PC fan-powered air purifier like the Luggable XL-7 from CleanAirKits, it’s clear that the 3Pro consumes more electricity at its maximum speed of 2900 RPM. 

That said, running costs for the 3Pro are similar to those of standard HEPA retail devices, but you do get much higher performance levels especially when you consider the much lower initial purchase cost.

Bottom line: Should you get the AirFanta 3Pro?

It’s totally worth it. This is the only air purifier with a a high CADR that you can travel with.

Here’s the thing: if you were to have come to me selling an air purifier with a CADR of 353 cfm for $159.99, I would have assumed it was some sort of a scam. The sheer power of such a device would surely cost a lot more, right? 

Adam Wong says no.

The AirFanta 3Pro can provide large rooms with multiple air changes for a price that is three times cheaper than what you normally pay for a standard, shop-bought HEPA air purifier. That is an incredible achievement that goes to show how brilliant Wong is and how much he actually cares about creating truly affordable solutions to clean the air. 

While the 3Pro is not totally plug-and-play (as you need to fit the filters and put the fans in place), it is MUCH easier to put together than all the other PC fan-powered DIY air purifier kits I have tested. That said, the 3Pro is also louder than all of them, so that is something to keep in mind.

For those looking for an air purifier they bring along when traveling or to events, there isn’t anything on the market right now that matches the high CADR of the AirFanta 3Pro. You can simply disassemble the device and pack it in your suitcase or backpack just to reassemble it wherever you need it. 

For those wanting a quiet and energy-efficient air purifier, they can leave running in the background even when having work calls or meetings at the office, then a PC fan kit like the Luggable XL by CleanAirKits or the Tempest by Nukit will be a better choice — just know that they will both cost over $100 more than the 3Pro.

Now, is sound is a concern but your budget can’t stretch beyond $160, then remember you can run your AirFanta 3Pro at lower fan speeds. It will be much quieter and still outperform the standard retail HEPA air purifier you can find online, costing you less upfront and in the long run.

I really love this device, so I expect you will find it across many of our lists of recommended devices. 

One last thought before I leave you: I believe everyone living outside the U.S. will really benefit from the AirFanta 3Pro, especially those living in places like the UK, where finding box fans and HVAC filters to build your own Corsi-Rosenthal box is virtually impossible. As if that wasn’t good enough, the 3Pro has a much smaller footprint than the standard CR box, is definitely quieter and offers much more adjustable fan speed options.
