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)

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.

People hate when you suggest airfanta 3pro here for some reason but it's literally a portable corsi rosenthal box that specs higher than all the other ones contained in hard plastic at 2-3x the price.

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.
