AirFanta - 3Pro

Glad to see this posted. It's the best one money can buy and it's not even close. I had one of mine die (it was one of the older models) and I was easily able to replace the fans + power supply and now it's working like new. Amazing product and repairable!

[AirFanta 3Pro](https://air-fanta.com/products/airfanta-3pro). Much higher clean-air delivery rate (CADR) than most commercial air purifiers (413 cfm vs. ~230 cfm), compact, quiet on medium settings, and easy to disassemble and bring to doctor's appointments/hotels/relatives' places if you want to mitigate airborne hazards away from home. Adam, the engineer, is also great about troubleshooting issues and replacing defective parts for free. If you'd prefer one of the brands on your list, Coway is good.

https://www.amazon.com/AirFanta-3Pro-collapsible-portable-suitcase/dp/B0D9D5L15F Basically a corsi-rosenthal that’s mentioned above without your having to get all the supplies yourself. You can pack it in your suitcase when you’re traveling as well. Had this in my hotel room when the wildfires hit LA in January and I was grateful. The owner is very communicative and will answer any questions you have as well. I’ve gone through a lot of air purifiers over the last 4-5 years and this one and the Dyson one are what I still use.

The AirFanta 3 Pro is one of the best affordable air filtration units available, now. High flow, low noise, easy to maintain. https://a.co/d/8qFNyFj

The PureZone mini has such a tiny CADR (10 cfm for dust at the highest speed, which is ridiculously noisy for how small this thing is!) that it serves as a false sense of security more than anything, especially if you're going to use it anywhere other than a small car. I'd recommend the Clean Air Kits Exhalaron (92 cfm for the 2-fan one and 128 cfm for the 3-fan one) or the AirFanta 3Pro (430 cfm at the highest setting, which is very noisy) if you have some extra space to spare (it's not as small as the Exhalaron but it is highly portable)

Unfortunately that's a low budget for the space's size. You are correct about CADRs; keep in mind those are minimum recommendations. If smoke particles/ash/soot levels are especially heavy, 800 CFM CADRs may not be enough. Usually the best value HEPA purifier is the **Winix C909** at [Costco Canada for $289.99](https://www.costco.ca/winix-c909-4-stage-air-purifier-with-wifi-and-plasmawave-technology.product.4000257649.html). Smoke CADR is 323 CFM. If you need to maintain a strict budget, you could consider the **AirFanta 3Pro**, inspired by a Corsi-Rosenthal box design. It uses proprietary Efficient Particle Air (EPA) E11 filters. [E11 is two filter classes below HEPA H13](https://www.airum.com/frontend/immagini/files/EN%201822-1.PDF). This means E11 is less efficient on a single pass, but allows for greater air flow and CADRs. The top speed's composite CADR is 413 CFM for the CARB Edition. [Price for one unit is $229 Canadian](https://air-fanta.com/products/airfanta-3pro).\* You would need two units running at top speed to meet the minimum CADR. \*I added the 3Pro to my cart and in checkout, selected Canada as the shipping destination to see the adjusted product price. AirFanta is not a big player like Winix, Coway, or Levoit. But their filters did sell out during the southern California wildfires back in January. I assume they're in good standing business-wise.

Assuming 2,8 m height, to achieve 6 ACH (Air Changes per Hour) you should have a total of 1.000 m³/h. So if you got two of the AirFanta 3Pro units I [recommended downthread](/r/AirPurifiers/comments/1kn1skq/dust_allergy_and_affordable_air_purifiers_whats/msrou4m/) and ran them at a medium setting it should make a noticeable difference in dust. The IKEA units are simply way too small for the space. To start off, I would just try one unit in the bedroom.

For affordability and high airflow (which is what you need for dust), it's hard to beat the AirFanta 3Pro. https://www.amazon.nl/AirFanta-3Pro-luchtreiniger-supergroot-opvouwbaar/dp/B0CJTYWQBT The IKEA units are cheap, but they don't have high airflow (ie CADR). So the cleaning power will be low because the pollutants "leak in" too fast. -- |Filter|Cost|Airflow|Airflow per Euro|Noise| :--|:--|:--|:--|:--| |IKEA FÖRNUFTIG|€59,95+€11,98/yr|120 m³/h|2,002 m³/h/€|60 dBA| |IKEA UPPÅTVIND|€29,99+€7,98/yr|95 m³/h|3,168 m³/h/€|55 dBA| |AirFanta 3Pro|€159,99+€67,99/yr |730 m³/h|**4,563 m³/h/€** (best)|50,2 dBA| -- But again it's not really about the value for money. It's more that you *need* such high airflow to make a dent in dust levels, especially since in real life people run air purifiers on medium due to noise.

The AirFanta 3Pro uses E11 filters (95% interception efficiency at the MPPS), whereas HEPA is 99.95% or 99.97% interception efficiency at the MPPS, depending on the standard used (US or international). Previously E11 was called H11 and *was* considered a "HEPA filter," but that has since been changed. The inventor chose this filter because it maximizes the overall CADR, so switching to a HEPA filter would actually make the filtration worse. https://x.com/Engineer_Wong/status/1899144721710408038 --- EDIT: Yikes, big pile of misinformation linked by /u/Justifiers below. And a nice downvote too for my troubles, probably thinking (wrongly) that I downvoted them. To save people watching a rambling conspiracy video (skip to 6:20 on the second video if you want), the YouTuber's objection to CADR is the data only goes down to 0.5 microns and not smaller (untrue, PM0.5 by definition measures *all particles smaller than* 0.5 microns, and also misinformed because at that size electret filters get *better* interception efficiency as the particles get smaller) and one RTINGS.com video which appears to show CR boxes performing worse than HEPA filters with lower CADR (contradictory, because elsewhere in the videos he extensively blasts YouTuber tests as unreliable and amateurish). Save your time and brain cells. Tl;dr yes **CADR is still what really matters** and not HEPA.

At fan speed 2 the 150's performance falls to CADR = 78 CFM, so HouseFresh doesn't recommend it for room sizes larger than 117 square feet. https://www.youtube.com/watch?v=gJWJX-FMxeo I'm not sure why anyone would recommend the IKEA Vindstryka because it's just an air quality monitor, not an air purifier. I wouldn't recommend the IKEA Starkvind either, because its noise and performance is similar to what you already have. Returning the Coway and getting an Airfanta 3pro might be a good option. I'm not sure about Auto mode on your Coway, but I would expect that ramping up when it detects particles and then ramping down when the air is cleaner so it's quiet most of the time is exactly what you would want? Take care.

Seconding air cleaners that use PC fans. The [AirFanta 3Pro](https://a.co/d/8LTLqZy) is great, but I admit a bit higher than the price point you mentioned. It moves and cleans the air quite efficiently even on the quieter speeds. I'd recommend buying from AirFanta/Adam Wong and avoiding the copycats. Clean Air Kits also has a [4-fan Brisk Box](https://www.cleanairkits.com/products/brisk-box) that does its job very quietly and consistently. I overlook the fact that it's more utilitarian than elegant, but I understand why that be a "no" for others. It has a small footprint too. One downside is that it's $104 for the kit, and the filters are an additional purchase which might not work for your budget. Plus side (at least for me) is that these filters are easy to get preordered to my local home improvement store.

I just purchased the air Fanta 3. If you want some really helpful reviews check out [house fresh](https://www.housefresh.com). Here is the review for [Air Fanta Pro 3](https://housefresh.com/airfanta-3pro-review/) that I recommended and purchased.

Best value for max CADR? AirFanta 3PRO $150 USD - adjustable speed, travels well, newer version can be used with power bank. Slight whine noise at highest speed. Want nicer looking/no whine? North Box or Clean Air Kits Standard unit, purchase off Amazon? Lago, hands down. I've bought 8? for various family members. I've bought air filters for ages due to allergies, and the only thing it doesn't do better than the Austin Air I have is clean smoke/odors. But I also bought 6 Lagos for the price of the last Austin Air replacement filter I got.

AirFanta 3PRO has the best CADR for its size and cost. On higher speeds it can have a slightly higher pitch that may be annoying.

Just get an air purifier with only the basics, no ionisation as that can contribute to ozone and make air quality worse. I actually made a mini CR boxes for myself and took it back with me to TW visiting family. It's amazing how dirty the filter gets only after 2 weeks in Taiwan. After 1 month it's as dirty as 6 months where I normally live. If you can source filters and pc fans, a dc adapter, and have DIY skills, you can definitely make your own most bang for buck in terms of CADR and power. I bought an AirFanta 3 pro for the house, but I don't know where to buy it from in Taiwan. That's only because the local options available here suck. There are heaps of diff brands and options in TW. Housefresh (on YouTube) has great reviews you could look at. Good luck! I didn't realise how much a difference clean air is until I started using purifiers.

Not true. For high pollution you want higher CADR, so even a CR box made with furnace filters would work well. H11 (E11) is actually the sweet spot for high CADR, that’s why the AirFanta 3pro uses them, as does the Clean Air Kits Exhalaron (neither available in India, however).

If aesthetics and noise levels are important to you, Coway ProX for the main living space (assuming it’s large-ish) and any Coway “medium spaces” unit (use their website to filter) for the Bedroom. Total ~$1k. If aesthetics and noise levels are not important, two AirFanta 3Pro, run on Medium-High, about $400. If aesthetics are not important but noise is, four AirFanta 3Pro, run on Low or Medium-Low, about $800. If your budget is a little flexible and you want the highest CADR with the smallest footprint and lowest noise, a SMART AIR BLAST - MKII for the main living space (about $1,100) and any Coway “medium spaces” unit. Total, about $1,500.

I’m a big fan of AirFanta 3Pro. It’s easy to put together, is very effective, lightweight, and you can collapse it down and pack it away if you save the box.

I have no idea why it would be called a scam. Adam Wong, the engineer regularly posts on X and there have been many positive reviews. I have both the AirFanta 3pro which has excellent CADR. At full blast it might be a bit noisier but I lent mine to a friend visiting and staying at a hotel and they liked the white noise and subsequently bought one. I have both the regular and the carbon filters (they can't be bought like a furnace type Corsi-Rosenthal). The Airfanta 4 lite is the personal laminal air purifier but it purifies just at your face and is not considered a room cleaner so you won't find a CADR for it. Some airlines allow them and some don't. Personally if I was traveling I'd bring an AirFanta 3pro as it's collapsible and has a better CADR than the Levoit.

Loving the Airfanta 3 Pro so far.

Hello. I know I am late to this post...however, I bought four of these for my home after being highly recommended in a different group. Everyone here is saying they are not True HEPA filters, however, on the Technical Details page of the product on Amazon, it says "True HEPA H11." I don't know much about these things... Is this not a HEPA filter? Can someone please explain? I'm not sure what "H11" means? I'm immune compromised and these seemed affordable and capable of 6 air exchanges for our small rooms. Now I'm very nervous these are no good. Advice? What is "H11?" It does say "True HEPA," I'm not sure if H11 makes it a lower quality? Thank you so very much. I appreciate you all.

Thank you very much for the kindness of your time. I’m still confused as True HEPA can be 10 to 15 correct? Or a bit higher for hospitals etc, meaning higher than 13. Why do the specs say True Hepa 11? Do you know? The replacement filters say it too. Thank you so much again.

the highest dollar per CADR I think is the Airfanta 3pro, but its a bit more finicky than a plug and play, and I don't know if it does smell very well. Between the two you have there, I'd go with the Winix.

that is true. I don't know how well they compare against the 5500-2, and one of selling points of the 5500-2 is that the carbon filter is separate (and apparently washable?) where as on the airfanta its bound to the filtration medium. But also it would raise the cost well over 150, where as just the airfanta 3pro itself is under 160 with the standard filter set.

You gotta up the budget if you want a pre assembled device. The best budget pick is the AirFanta 3Pro with carbon filters. I know it's not the most attractive device but it performs incredibly well for the price. If you ran it at its highest fan speed it can provide close to 5 air changes in 680 square feet https://housefresh.com/airfanta-3pro-review/

How big is the space? The best bang for your buck is the AirFanta 3 Pro. It's not the most aesthetic machine but it purifies around 500 square feet with about 4-5 air changes an hour. If you think your cat would jump or scratch at it, it may be worth getting the Winix 5500-2. It purifies a smaller area- 300 square feet or so.

Levoit Core 600s if odors aren't a huge consideration. AirFanta 3Pro isn't the most aesthetic device but it covers a large area (650 sq ft) for a very reasonable price. Coway Airmega 400 is a good device. I would wait for a sale. Smart Air Blast Mini or MKII if you have a large budget and don't need to move the devices often.

Multiple units in one home isn't overkill. How big is your room, the one you spend the most time in? If you're not super concerned about aesthetics and smart features, the AirFanta 3Pro has a high clean air delivery rate for the price. You could buy a number of those and put them throughout the house.

AirFanta 3Pro with carbon filters? I'm not sure how big the litter box area is since this is a device that takes up a bit more floor space than usual. The AirFanta does have a high clean air delivery rate, especially for the price. You could run it at the lower fan speeds and still achieve good air cleaning, depending on how big a space you need it for. Have you tried different litters? I've found Arm and Hammer to be good for odors. Do they sell that brand in Canada?

The size of the fan and the filters matter. This small device isn't going to effectively filter the air in a 1,000+ sq ft space as it's being advertised. As someone still taking COVID precautions, I'm not depending on this device as a mitigation layer. Even if I had bad allergies, it's not going to effectively clean the air compared to a Winix 5510 or AirFanta 3Pro

The air Fanta can break down easily and you shouldn't have an issue taking onto a plane with carry on, I'm not sure if you'd be able to bring a commercial plastic levoit the same way but checked bag would be fine then. Some people here months ago were saying the air Fanta is a scam and is only shilled for here but it felt like actual reviews from real people when I was discovering it and from my personal experience using it I've found it nice and portable especially since it can run on a USB c power bank and adapter for lower voltage.

AirFanta 3Pro for sure. Highest CADR per dollar of all the PC fan air purifiers, and it’s not even close. The non PC fan purifiers use way more electricity, too.

yeah I tried putting together a parts list a while ago to make one in the UK and it was both cheaper and easier to just get an airfanta 3pro, which is basically the same concept albeit with proprietary size filters. even the filters were still cheaper than buying locally (£42 instead of ~£80) but maybe that's different now that IKEA sells filters

If you’re able to have some kind of surface to place it facing you when you have appointments then I’d suggest the AirFanta 4Lite which is a portable laminar air flow (not big enough to clean the room, but able to send a straight stream of purified air toward your face if there aren’t strong air currents around). It’s more meant for if you have to eat in an unsafe space. I’ve used mine for meetings in cafes. It’s very sleek and white and fancy looking. Has inbuilt battery (rechargeable) that lasts a few hours; can also be used with power banks. I’ve carried mine in knapsacks but it does take up some space. Also would suggest on top of this the AirFanta 3Pro which is strong enough to clean a room (packs more punch than other purifiers of its size but can be a little more noisy and doesn’t look as sleek for sure as its like a CR box). Mine just stays in my living room. It’s portable (packs flat for carrying, pretty light) but I wouldn’t to dismantle and set it up again more than once or twice a day; it’s a little fiddly. You didn’t ask about masks but just to mention that the Zimi Air is super breathable with no metal pieces. I use the earloop for large conferences and so far it’s kept me safe.
