AirFanta - AirFanta 3Pro

I like my air Fanta 3 pro !

Yeah, as others are pointing out the pandemic is far from over. Air purifiers are a great idea. We have them in every room of the house. Get them to cover double the sq ft than the room you’ll use it in so that you can get the same coverage on lower settings. The Levoit Core series is good, has a small footprint and is pretty affordable. I’ve sent these to family. Shout out for the [Air Fanta 3Pro](https://air-fanta.com/collections/all) because it folds down and is portable for travel. [Clean Air Kits](https://www.cleanairkits.com/collections/shop-all) are also awesome. I just got the [Exhalaron](https://www.cleanairkits.com/products/exhalaron) to use for doctors appointments etc.

I have a PureZone mini that I take to doctor and dentist appointments. I just got an Air Fanta 3 Pro for my room for the rare occasion I have to travel. Edit: Why the downvotes? Are these not good? Is it because I got the AFP3 to occasionally travel? I’m a 4.5 year long hauler. I don’t get to do much but when I do I try to be as safe as possible. Whatever the case, I’d appreciate knowing more instead.

I have an air Fanta 3 pro. It sits on a side table right beside my bunnies cage. It’s very quiet and works extremely well. I think you will be pleasantly surprised by how little bunnies smell. There is no smell from our bun’s enclosure. We have the air purifier to catch fluff and dander as my husband is very allergic. If you get a very fluffy bunny, I recommend the air purifier to catch the wispy floating fluff balls.

Seconding the recommendation for the Air Fanta 3 Pro! I love mine. Quiet, efficient, cheaper price, and best of all, it folds up so it’s easy to transport when you’re going to other places! Best bang for your buck. Read the House Fresh review.

Cat allergy person here as well as fragrances (which I don't have to worry about at home). IQ Air in bedroom (expensive and expensive filters and is good). In experience one would be AirFanta Pro3. You may want to consider getting the carbon filters for it and read up. Beside my bed have the Medify 15 so that'll helped a lot...a room one and a small bedside one for the bedroom.

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.

Yes, a new version that's more attractive is coming out soon but if you don't mind the looks the AirFanta Pro is amazing (Amazon or their own website). 4 large filters and the testing is amazing for air quality. And at $169 is worth it. I followed along with the design and R&D.

The AirFanta 3 Pro. Get the one with carbon filters. It's a powerful device and should be able to clean the air fairly quickly since your room is small.

About how large is your office? My first thought was AirFanta 3Pro with the carbon filter. It's over your $200 but not by a wild amount. The Winix 5500-2 is another option. I'm not sure how strong the fumes are but either of the two devices will help. Neither have a ton of carbon if the fumes are super strong but it will help. The AirFanta will give you more air filtering per hour if your office is small, depending on the speed you set it on.

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.

Depends on the size of the room and how fast you're expecting to clear the smell. It works well for my living room for 420 but I ended up getting an AirFanta 3Pro with carbon filters to help out because of the size and layout of my space. I could clear my living room and hallway faster with the AirFanta alone.

AirFanta 3Pro. It's not the most aesthetic machine but it has great specs. Rated for a room around 500 square feet. They have a version with a carbon filter. I've been testing it and it cleans the smell faster than my Winix. To be expected with a higher CADR. The Winix will help a lot if you're in a smaller room, like 275 sq ft max

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.

It's *slightly over your budget but the AirFanta 3Pro with carbon filter. High CADR (clean air delivery rate) for a great price. It's very lightweight which will help with moving it to different rooms.

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

Thank you for the clarification. I agree with what you said. And we are shipping some 3Pro with carbon filters in it.

We are working on a better aesthetics model, and with PM sensor, screen and APP.

>It's a giant CR box Having used both, the 3Pro is definitely not "giant." It's a 1 foot cube. >with all the CR box problems IMO the biggest problem with CR boxes is the noise, and the 3Pro is a lot better than a CR box on that front. >High replacement filter costs The first-party replacements are similar to the Winix, no? But yes, with a current lack of 3rd-party filters it is a bit more expensive than alternatives, for people who are willing to use non-OEM filters. >no HEPA (the filters are EPA11 at best) This from coming the person who (very correctly IMO) is always pointing out that CADR is a better metric than interception efficiency. Adam Wong did the math and determined that (for the PC fans used) an E11 filter delivers the highest possible CADR. https://twitter.com/Engineer_Wong/status/1769965319945347394 >No carbon filter, so no smell reduction. Add-on carbon filters get pricey Personally I like separating particle and VOC filtering, since you tend to be able to do better then trying to find one unit that does everything. Also odd to say it has no carbon and then flip and talk about the carbon filter. But I do agree, it would be nice if you could order it with the carbon filter as standard. Pinging Adam Wong (/u/Sad_Gear4867), are you listening?? Anyway, I really do appreciate the excellent work UncleGurm does (in this thread and elsewhere) to educate people about air filters, but I confess I don't understand this grudge against Airfanta.

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.

You can put something under the door but it won't block everything. Air can come in through the sides and top too. The risk is low, but wildfire smoke has been a good proxy for how particles can travel through those tiny cracks. Not sure if shared air via ventilation system would be a concern? Love my air Fanta 3 pro after many weeks of researching but it's not the cheapest - it does have a really good CADR to price ratio though and it's quiet too (noisy on max but good noise to CADR ratio) The thing to consider with air purifiers is the replacement filters. Some will say you change the filter once a year but can gunk up in a month. Some have hard to find replacement filters. Some have cheap initial cost but expensive filters. For a cheap air purifier with easy to find filters, Ikea might be a good option. Here's a spreadsheet with CADR, price, noise levels, ratios etc. Select your country. Minimum you want is 6 air changes/hour, I'd aim for 12 though. You can calculate with online calculators, just make sure units match up (CADR units, room dimension units in ft vs. meters, etc.) https://docs.google.com/spreadsheets/u/0/d/17j6FZwvqHRFkGoH5996u5JdR7tk4_7fNuTxAK7kc4Fk/htmlview# Eta: I popped it into a calculator, air Fanta at 9v gives you a CADR of 328 cubic ft/min so 13 air changes/h. 48 dB A cheap Ikea one only has a CADR of 44 cubic ft/min which wouldn't be adequate. Air Fanta is one of the cheaper options on this list. But if you're in the US I'd also be concerned about tarriffs?

I don't know what "v9" is because that's not a lot of info (there's no brand or anything), but as I said, you want 5-12 air changes per hour. I wouldn't personally be comfortable with 1 air change per hour even with a draft stopper. The numbers I crunched for you showed a CADR of around 330 cubic ft/min = 13 air changes for your room size, so you'd want a CADR of around 150 cubic ft/min at least (pay attention to units, some advertise in cubic m/hour). If you show me the listing I can look at it, but you should have a look at the spreadsheet and try to find an air purifier with the minimum CADR of 150 ft3/min. Eta: by v9 do you mean 9v air Fanta? The voltage is just a specific level on the air purifier, but if Airfanta 3 pro is the one you got, you're more than okay. I checked the listing and it's once for a 3100 *square* foot room (presumably on max speed), so that means length by width. Your room is 11x17 which is 187 square feet. Definitely more than enough, you're golden

Oh okay yes so if you have the Air Fanta 3 Pro, the 9v is just the voltage, and it's because they measured the CADR at various levels of power. There is only one Air Fanta 3 Pro and the voltage can be changed up to 12v. When you get it you'll see there's a dial that goes up to 6. Presumably 12v is the max and 6 is the max, so step 3 (half power) is 6v. I think you are confused because it is a math/geometry issue. Keep in mind that ft, ft2, and ft3, are different units and indicate different measurements (length, area, volume). There are different ways to measure room size: area (square ft/ ft2) or volume (cubic feet, ft3). Area is just the floor size, volume is the total 3d space of the room. The 3100 ft2 room being cleaned once that you are referencing is referring to area (which is indicated by ft2). The Air Fanta listing is mentioning the size of the room in square feet. This means they're measuring the size using the area of the floor. This is not the ideal way to measure because ceiling heights vary and we don't know what height they're using. But it's saying that a floor area of 3100 ft^2 gets cleaned once per hour. This is equivalent to a rug measuring 55 ft x 55 ft. Your floor area (or rug) is 11 ft x17 ft which is 187 ft^2. It is far smaller so there is nothing to worry about. Your room's volume is: 11ft x 17ft x 8ft = 1496 ft^3 (cubic feet - sorry, not sure how to format on reddit but it's an exponent). You're multiplying 3 dimensions, so you just multiply 11x17x8, and ftxftxft, to get 1496 cubic feet. you can visualize this as 1496 cubes of air measuring 1x1x1 ft. I have no idea how you got 3400, but the math does not check out lol. The fan is not necessary but it can help circulate air more. If you plug into an air exchange calculator, you can check for yourself. https://www.omnicalculator.com/construction/air-changes-per-hour Make sure the units are correct as the default is meters not feet for each item. Area is 11x17 so 187 ft2 Height is 8 ft CADR (from spreadsheet, at 12v is 534 ft^3/min) ach=21.47 On max, it's cleaning the room 21 times per hour. You're golden. At half speed (6v) CADR is 213, and so ach is 8.5. Even at half speed, your room will get cleaned 8 and a half times per hour. I'd aim for 12 changes, which requires a CADR of 300 ft3/min, meaning ideally keep the dial between 4 and 5. if this helps, CADR in ft3/min is basically like how many 1x1x1 ft cubes of air can it move in a minute? 534 1ft boxes of air, in fact, at its max. Your room is 1496 cubes of air, so to get 12 air changes per hour, you need to move 12 x 1496 cubes of air (17 952 cubes of air). There are 60 mins in an hour, so the air Fanta on max, moving 534 cubes of air per min is 534 x 60 = 32 040 cubes of air per hour. So if your room is 1496 cubes of air, and you're moving 32 040 cubes per hour, 32 040 divided by 1496 is 21.42 changes in air. Which you can round to 21 changes. If the numbers are challenging, think of it like your room is 1 cube of air and the air Fanta can deliver 21 cubes of clean air per hour on max. So on max, you're moving almost double the amount of air you need to keep the air clean (because you want 12 changes) . I know it's a lot of words and the numbers can be confusing if math isn't your strong suit so feel free to ask for clarification. I don't have the spoons cuz I have long covid, but I'd draw a diagram otherwise.
