FAQ
AirFanta 3Pro is designed with a compact form factor comprising of four High Efficiency filters and four powerful 140 mm computer fans. This allows it to move a high volume of air through the filters faster than other room air purifiers, while maintaining a good balance with noise levels and power consumption.
You can find this information on the specifications page.
The number of units you should buy and use depends on the size of the room(s). Generally speaking, we recommend targeting at least 6 ACH (air changes per hour) for homes and offices (NEA recommends 5 to 7 ACH), though the higher the number, the cleaner the air. Assuming you have three rooms with a height of 2.6 m that are between 10 m² to 20 m² each, buying 1 unit per room and setting the speed to setting 3 (for reference, the highest speed is setting 6) will provide between 8 to 16 ACH per room.
For more information on calculating air changes per hour, please check out free calculator or read our article here.
As for other types of premises such as restaurants, schools, and clinics, we recommend following the ASHRAE 241 standard.

Yes. Testing from an independent laboratory showed that AirFanta 3Pro (standard: T/GDAR 0001-2020, test report: KY202300057) removed 99.99% of the H1N1 influenza virus.
As for SARS-Cov2 (COVID-19), based on findings from multiple studies, there is strong evidence that the virus resides in exhaled aerosols in the 1 to 5 microns range. AirFanta’s filters can remove 99.4% to 100% of viral aerosols in this range.
Our findings from both H1N1 and SARS-Cov2 (COVID-19) should also apply to other kinds of airborne viruses as well, as the size of viral aerosols exhaled from an infectious person doesn’t change much regardless of the type of virus.
Yes.
The High Efficiency filters can capture harmful particles from haze and wildfire smoke, however they cannot capture harmful VOCs (volatile organic compounds) that may reside in them, and they cannot remove the haze or wildfire smell. In addition, the filters may have to be replaced sooner compared to High Efficiency + Activated Carbon filters, which are more efficient at capturing denser haze particles.
If you need filters that capture VOCs, remove smells, and last longer during haze season, you should go for the High Efficiency + Activated Carbon filter option.
No, it does not emit ozone, ions, or UV. Please be careful of products that emit ozone or ions as they can produce air pollutants and pose a health risk to humans and animals. People with respiratory conditions such as asthma are strongly advised to stay away from such appliances.
Yes, but you will need find a way to connect the DC port to the power bank.
The High Efficiency filters should be replaced every 6 to 12 months, and the High Efficiency + Activated Carbon filters should be replaced every 4 to 8 months. When replacing filters, replace all four filters at the same time. One set of replacement filters comes with four filters.
The filter lifespan largely depends on environmental conditions. For example, you may need to replace it more often when using it under environmental conditions such as haze or wildfire smoke. Visually inspect the condition of the filter (if it looks black or appears to be full of dust, it should be replaced!) if you are unsure. Filtration efficiency and air cleaning performance will be reduced when the filters are dirty.
That depends on what your needs are.
The High Efficiency filters are capable of filtering many different types of pollutants, such as viruses, dust, mold, pollen, allergens, smoke, haze, pet dander, and PM2.5.
The High Efficiency + Activated Carbon filters are capable of filtering everything that High Efficiency filters can capture, as well as pollutants such as formaldehyde (chemical associated with new paint smell), VOCs (volatile organic compounds, haze smell, cigaratte smell, cooking fumes, odors, and chemical gas.
Generally speaking, the High Efficiency filters are sufficient for most use cases, but if you are trying to reduce a smell or odor, you should go for the High Efficiency + Activated Carbon option.
Also, keep in mind that you can purchase both types of filter replacements and switch between them anytime.
The outward-facing side of every High Efficiency filter / High Efficiency + Activated Carbon filter has black grills (wire-mesh netting) attached to it to prevent children and pets from touching the filter material.
While not necessary to do so, you can gently wipe away dust that appears on the black grills with a cloth or towel. If the filter material itself seems to be black or appears to be full of dust, you will have to replace it.
Yes, but you should use the laminar air purifier away from the AirFanta 3Pro. This is because the turbulent airflow from the AirFanta 3Pro could interfere with the laminar airflow of the laminar air purifier and reduce protection.
Yes. Make sure that the plug you are using is able to support the AirFanta 3Pro’s watt/voltage requirements.
Yes. This will ensure that the air in the room is constantly cleaned at all times.
Yes. Local warranty lasting 1 year is included with this product. You can also purchase extended warranty for a peace of mind.

takes a few time to assemble it but the result definitely worth the hardwork! Wow, I can adjust the flow rate! 3V means low flow rate and 12 v means high flow rate!

Really like how easy it is to assemble and disassemble it so could be a very good option to pack in a bag or box and travel with

At this price point (got mine for $150) it’s a no-brainer: get one. It’s super versatile.
– Not sure about the air quality at your travel destination (eg, hotel room, doc’s office, classroom, etc)? Pop one of these in your luggage, or a tote bag, and assemble it on arrival.
– Need to quickly clear the air in your room? Turn this thing on high.
– Want a quieter filter to run all night while sleeping? It’s got adjustable fan speed, so turn it down a bit.
– Doesn’t take up a lot of space, comparable to a mini ice chest or a throw pillow.
Pros:
– Very high CADR for the size
– Fits in a tote bag or carryon
– Adjustable fan speed
– Fairly priced. DIY version with similar size and performance would cost the same or more (buying from Amazon and Ikea for filters).
– Much smaller than furnace filter filter boxes
Cons:
– Pretty loud at max fan speed when sitting next to it
– Assembly can be a bit finiky

So easy to put together! Great air flow. Quieter than my HEPA filters. Nice metal on the outside of the filters. Can’t wait to travel with it!
Mitchell –
The parts are all way thicker and more sturdy feeling than I expected. Feels extremely solid. It pumps a LOT of air on the highest setting and can be adjusted down so that it’s super quiet. I’m really happy with this and think it’s probably one of the best air purifiers available at the price (and I think it punches way above it’s price range)
J E –
I spend “a lot” of time reading air purifier reviews from independent reviewers and this Air Purifier caught my eye. It’s not too big, easy to put together and gets great CADR. I highly recommend this box. We plan to use it at the mid-voltage and like that the fans speed can adjust according to the current needs.
Scott –
Powerful air throughput for the size. Compared to a DIY CR-Box, the fans are quieter, the power switch allows for greater control of speed/noise, and it looks commercial/professional. It goes together easily with a tiny bit of fuss to get it seated within the housing, but that’s because the edges fit tightly together without the use of box tape so it takes a moment to make sure everything is snug…no tape means a much more finished, professional look. Bought one for ourselves, and one as a gift for someone who needed something that did not have a homemade look.
Curtis Le –
DIY/CR-Box style air purifiers are incredibly effective tools for cleaning the air in small spaces, like homes or hotel rooms.
The problem with most air purifiers is balancing a high CADR (clean air delivery rate, how much clean air the device pushes), noise levels, and portability/storability.
The Airfanta 3Pro manages to deliver top marks on essentially all of these fronts.
Portability: due to the easy to assemble collapsible design, the 3Pro can easily be put into all kinds of bags/luggage.
CADR: despite the relatively small weight and size, the 3Pro delivers one of the highest CADRs of any commercial air purifier, but also some of the best bang for buck at the current price.
Noise level: the only real downside to this device is that it isn’t whisper quiet due to the minimalist design. At max power (12v) it is tolerable to me, but certainly not quiet. However, there is a power control device for you to use to change the voltage based on how much filtration is needed vs how loud you can afford to make.
Highly recommend if your looking for either a great value air purifier in general, and especially if you need one for frequent travel and temporary lodging.

I purchased 4 of these (2 for my house and 2 for family). It’s great that they are portable but I’m using this at home.
The Clean Air Delivery Rate (CADR) is excellent for the money spent. Transparent and honest specifications (certified results) unlike many other manufacturers who mislead either by not clearly stating CADR (CFM) at all or through gimmicky marketing terms. This box is simple and effective.
When looking for an air cleaner the thing that matters most is CADR. This affordable box delivers! Finally.

Quick to assemble, easy to take apart/pack, and does an awesome job at cleaning the air. We’ve tried many brands over the years and thought some others were pretty good, but this one is the best so far! Pollen is off the charts high atm, and the AirFanta makes our indoors totally comfortable for our allergy sufferers. No other filter ever managed that. Highly, highly recommend!
Heather –
This air purifier is incredible. It is quieter than other air purifiers that are less powerful. The fact that it can be broken down to be portable is so convenient. It was very easy to put together. Instructions were easy to follow- and barely needed as most everything is self explanatory and simple. Very high quality. Absolutely genius. EXTREMELY good price for what this is!
Rhone –
So far we have been using the air purifier for over 3 weeks and there are no complaints. It does what is says it will do. The air is cleaner, it works very well. I have noticed less clogging and easing in the house and it keeps the air crisp. No complaints from here.
PP –
This AirFanta 3Pro is incredible. Very portable (comes with its own carrying case!), very easy to set up, and has incredible cleaning power/CADR. It is also very quiet at lower speeds and has adjustable speed control. Excellent effectiveness and affordable for the power it provides. Great for cleaning the air of viruses, allergens, and wildfire smoke. I recommend it to all my friends/family.
Ean Jay –
This is a HEPA filter fan with realistic specifications – one of the few on the market. Simple, straightforward and very quiet, no glitter or glitz, but a unit that will sit quietly in the background and perform better than most of the other fans on the market – regardless of price. Buy it today for tomorrow!

So it’s a portable highly effective high CADR unit. It clears PM2.5 rapidly from my home. It is easy to move around, very light, portable, easy to adjust the intensity. It’s not pretty, and is loud on the highest setting. But it is extremely effective for the price. It’s probably my second best purifier, and I own many purifiers up to $1000 in price. I love that I can put it on the kitchen counter to clear PM2.5 and smells in the home that does not have a hood vent. Within about 15 minutes after overcooking something on the stove it can clear PM2.5 from 100 to about zero on high. Very impressive unit. If I were on a budget and did not mind the aesthetics, I would put one of these in every room in the house and one in the kitchen, maybe even one in the car. Overall. A+ unit and design. Not fancy, but effective and simple for a portable CR box.

About two weeks ago, I threw one of these into a carry on (well, not literally, but it was that easy to pack). I then set it up in my hotel room, where it has been running for a week.
Best and most efficient filter I have used, the only things to keep in mind is that there is 1) no UV light if that’s a dealbreaker for you and (very minor) it may take a second to set up the four filter panels so that they all fit tightly together at right angles, but it’s worth it, because it’s so efficient and this means are no extra little gizmos to keep track of and/or misplace.
Set up easily (with jet lag and a sprained foot) without needing to refer to directions. Not only does it quickly filter my hotel room, but it provides exactly the correct amount of white noise to drown out any hallway sounds (I happen to be not that far from the elevators this trip.)
I also noticed the other day that my sinuses are now also completely clear. Which almost never happens in a hotel room, even at the 5 star-eco-cleaning-standard level. (This is a more average, if solid, property.)
I’m leaving this one behind for my mom, confident that it will easily filter her apartment, and just ordered another for me.
Dr. P –
This HEPA filter does everything correct. The CFM is insane. The fans are fully able to be controlled to your exact speed flow and sound level desired. This truly can exchange the air in a room at a rate that is really able to protect someone unlike many other rivals that just slowly help by the hour. The assembly of the product is super easier, small, easy to pack up, has a power unit that changes volts to control the fan, and is built I think best for portable use. It is not going to withstand someone falling on it so you should put it in a safe spot. Overall I am mighty impressed by this device and will be getting a second unit in the near future. There is nothing as efficient power wise, air flow wise, size wise, price wise, and weight wise as the air fanta HEPA unit.
Dr Julia Lawton –
I already own a Eoleaf and Phillips 3000i purifer. This item is more compact and seems to pack a much more powerful punch – the fan is impressively strong and, due to the design (filters on 4 sides of a cube), the 3Pro is very well placed to offer extremely good and fast filtration. It is a ‘no frills’ purifier with a simple design. A really important consideration is the cost: it is not only much cheaper than other comparable high spec items on the market, it is also much more affordable to maintain as replacement filters cost a lot less than those for the other purifiers I own (about a half to a third of the cost). All in all I am very happy with this product.
Renee Aguilar –
Works perfectly, is a little loud at its highest setting but it’s a small tradeoff compared to the amount of protection it provides me in my home. My only regret is not buying it sooner.
Arty D –
Using 4 computer fans instead of a box fan is the best and worst part of this design. Best, because they are DC motors and run slow and quiet. Worst, because they require a power supply. Others have commented that it runs warm, it does, very warm. Funny , since the fans were designed to cool power supplies.
Emma –
Fantastic little device! Thoughtfully designed, very impressive performance, and super reasonable pricing.
Customer support has also been fantastic: my unit arrived with an annoying but otherwise innocuous whining sound at low to medium fan speeds, and after letting them know they graciously sent an entire replacement unit, even though I just asked for troubleshooting help.
