3Pro, Air purifer for house up to 3100ft2, CADR super large 413cfm, collapsible and portable, can be packed into a 20" suitcase.

We went on a multi-week, cross country vacation right in the middle of COVID, RSV, influenza, norovirus season (late 2024). We stayed in so many different hotels, in so many different states, I’ve lost track (>10). We relied on AirFanta HEPA air purifiers to mitigate our hotel rooms.4 AirFanta air purifiers easily fit into one bag. That’s enough fire power for about 20 ACH (air changes/hr) in each hotel room! The air in our hotel room was likely far more disinfected and clean than any hospital. Even with our children in stow, we had ZERO illnesses on our multi-week vacation!!!The portability this AirFanta air purifier offers was also instrumental to our ability to a healthy vacation. 1 AirFanta has about as much CADR (clean air delivery rate) as the largest Levoit air purifier!!! Now imagine lugging around 4 large Levoit air purifiers while on a cross country vacation with your children in tow…not appealing, in my opinion. Just one bag carried all 4 AirFantas and it was still lightweight.Sound level: as compared to traditional air purifiers, the AirFanta air purifier is much quieter. This allowed for us to clean the air in our hotel room while allowing us to sleep comfortably due to tolerable sound levels. Likely 2 AirFanta air purifiers is all you need for any standard hotel room. We just wanted to double up to allow for deployment in multi-room hotel suites (which is why we bought/used 4 of them). Worked amazingly well.Tips for illness prevention during travel:1–Mitigating against airborne transmission is exceptionally easy to accomplish with AirFanta’s air purifier. I highly recommend using an ACH calculator and aim for a minimum of 12 ACH (air changes/hour) in public locations.2–When not in your hotel room, wear fit-tested respirators in public places where there is any shared air. I recommend using a nebulizer and 3M’s Bitrex (FT-32) liquid to perform the fit-test (instructions are on line for free). Both the adults and children used fit tested respirators while on vacation and they worked remarkably well. We went to crowded, indoor public places, saw movies, exhibits, etc, had zero issues with illnesses.3–When you initially get to your hotel room and have your AirFanta devices set up, let them run for 45-60 minutes before removing your respirator (at minimum 12 air changes). Have one AirFanta by the hotel’s door and a second towards the middle of the hotel room.While I cannot guarantee zero illnesses with this method, I can speak to the success we had in terms of illness prevention.In our experience, no other HEPA air purifier on the market comes close to AirFanta’s portability, CADR (clean air delivery rate), & sound volume.

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.

Very efficient no frills filter with an elegant design. I would recommend.

Ce purificateur d'air est très discret tant qu'il n'est pas à la puissance maximale (avec un volume d'air filtré un peu réduit mais encore très élevé par rapport aux autres marques).Très facile à monter, à ranger, léger à déplacer.

El envío no tuvo problemas. El dispositivo es fácil de armar y manejar. Cumple su cometido.No hace gran ruido.Recomendado.

TLDR version:Pros: CADR (Clean Air Delivery Rate), portability, excellent carbon filters, price, comes packaged securelyCons: Aesthetics, slight fan noise/ pitchiness at speed 4 and aboveWhile I'm not the biggest fan of the device's aesthetics it has excellent CADR for a very reasonable price and It's fairly portable. It's certainly a step up aesthetic wise from your everyday box fan CR box.I wasn't sure if the carbon version of the device came with regular filters as well and it does.I haven't had my device for very long but I'm loving it. I was well informed of what I was getting thanks to social media and independent reviews.The carbon version is great for indoor gardeners who quickly want to rid a room of the smoke and smell. My cat has a sensitive respiratory system and this helps me quickly clean the air. Also great for airborne virus mitigations thanks to the excellent CADR. I'll be buying a dedicated backpack for easier portability.I don't mind white noise so speed 3 is fine with no TV. I find 4 okay when the tv or music is playing. Everyone is different.I can feel the difference when I have this device on.Overall I'm very pleased. I've recommended the product to others and its great to finally own it myself. Excited to purchase the more aesthetic iteration later this year. Hope the company keeps up the great work.

after doing some research on air purifiers, my conclusion was that DIY CR boxes were by far the best value for money besides being way more effective than the automated, fancy looking & expensive HEPA filters. Soon realized though that the needed materials aren't that easy to source in EU. When I found this one, I knew I found the perfect middle ground. The design I had in mind, HEPA filters, big volume of air refresh rate and 2min to build up. No tape, screws, silicone or glue. The operation is very basic, turn the knob from OFF seamlessly to full blast, and boy does it blow. It's very quiet at low speeds, perfect for when I'm sleeping, just next to my bed. At full fan speed, it's quite loud, imagine a DJI drone taking off. Tip: there's a velcro wrap tie in the package to keep the filters in place while fitting the top over them, takes a bit of patience and finesse to get it in place, but that helps securing an airtight fit

I absolutely love this product - so portable, easy to set up, and powerful air cleaning. It’s a 5star product.I am having a problem with one we bought last summer and haven’t used much. It was making weird noises. Today I turned it on and a tiny bit of smoke came out of one of the fans and it stopped working. I really hate to throw it away. I have no idea how I might fix it. Any ideas?

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.

best purifier on the market, especially for the price. levoit? more like AVOID amiright! get an airfanta asap
