AirFanta 3Pro

I like my air Fanta 3 pro !

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.

I would say that my experience is you want WAY more dehumidifier than you think. I have an old leaky 800 sq foot house.  I have two dehumidifiers that are rated for up to 10,000 sq ft in total.  Like 80- 100 quart capacity.  That’s what I needed to keep my house But definitely get separate air purifier and dehumidifiers. Someone suggested air Fanta, that’s a great option.  Or check out cleanairkits.com. For an allergy you want to change the air in a space 5-10x an hour. So do a little research on what CADR is, find some good videos of people testing your purifier.  You will notice a difference and probably be healthier too.

I have a levoit core 300s and it's fine but I like my air Fanta more it makes less noise and is more effective I like that the levoit has an app though and it looks.more modern

Sorry for the stalking I was trying to find your recovery post and saw this post anyways I have the levoit core 300s and the airfanta pro 3 and the airfanta pro 3 is wider but less tall but I still prefer it over the levoit. The levoit needs to be on mode 3 to be somewhat effective and it's really noisy at that point. The airfanta pro I have at 3 (out of 6) and is way less noisy and according to the stats more effective but replacement filters are more costly. Housefresh.com has a lot of good reviews on different type of airfilters

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.

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.

I have two AirFanta 3Pros and they capture a lot of hair. I have one in my hallway and that one captures the most but I'm still surprised every two weeks at how much hair I vacuum off the one in my bedroom as well. It's not the most attractive device but it's one I recommend if people want to capture pet hair well

Wirecutter tends to repeat whatever the manufacturer says. They don't test the air purifiers in the same way House Fresh does. House Fresh is testing for 5 air changes an hour on the highest setting. AirFanta Pro is a good option. It has certifications from China. For the bedroom the Levoit Vital 100s would be a good option. If you aren't super concerned about aesthetics, Clean Air Kits' Brisk Box could work for the kitchen/ living room. They're devices are very quiet. The Brisk Box is rated for 300-450 square feet

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

Unfortunately the AirFanta 3Pro is ugly but it's great for pet hair. The creator has pictures of it caked in dust from his child's classroom blackboard. The attached picture is mine with 2 weeks worth of cat hair https://preview.redd.it/pqtu9lbdaf6g1.jpeg?width=3024&format=pjpg&auto=webp&s=e870086cde7b4d3829c08cf961ab39ef13763a6a

Not a great buy. Incredibly overhyped. The CADR for the speed most people are likely to run it on is comparatively low. You’re better off getting a Winix 5500-2/5510 or an AirFanta 3Pro if you don’t care about aesthetics. AirFanta can clean a larger space/ has a higher CADR and is a better bang for your buck.

Yeah, get the AirFanta 3Pro with the carbon filter. It has a higher CADR and more mainstream brands would charge 2-3x for that CADR. Though it would suck to have to mask at home, it might be worth getting some KN95s to wear at home. A mask is just an air filter for your face.

I have the Winix 5500-2 and 2 AirFanta 3Pros. I have a Levoit Core 200s I run just for the heck of it. I wouldn't recommend the Starkvind. It has a pretty low CADR for the price. It's hard to recommend just one device without knowing the room dimensions and motivations (odor, allergies, cigarettes, weed, COVID, etc) but I tend to recommend the Winix 5500-2/5510, some Levoits, AirFanta, Clean Air Kits, and Smart Air. I rely a lot on House Fresh and the COVID informed community on Twitter. There's also Airpurifierfirst.com

If you're trying to prevent COVID, are you masking outside your home? My favorite lightweight air purifier is the AirFanta 3Pro. There's also the Smart Air Sqair air purifier

Honestly you're probably better off with a AirFanta 3Pro. Mine get a ton of cat hair on them. Granted one is in my hallway and my cats pass through there a decent amount. The one in my bedroom also sees a decent amount. I vacuum them both about every two weeks. I've gone longer but like to clean it the same as the pre-filter on another device. It has a high clean air delivery rate and it's a very good buy for the price.

With that budget, your best bet is the AirFanta 3Pro. I have an asthmatic cat as well and have two AirFanta 3Pros. I often recommend it for cat caregivers or anyone else with a pet that sheds a lot. It picks up a ton of cat hair!

You're better off with an AirFanta 3Pro if cat hair is a big concern for you. My 3Pros are great at catching cat hair.

Since you said the bedroom is "not huge," and since dogs have sensitive hearing, I would recommend an Airfanta 3pro (non-carbon) over a CR box. Similar design but it's smaller and quieter, and it fits your budget perfectly. I believe it's still $152 with the code HOUSEFRESH on their website.

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.

Obligatory recommendation for the AirFanta 3Pro. One of the best CADR-per-dollar and CADR-per-decibel options out there, and it doesn't have an ionizer which is bad for birds.

Smoke is tiny *particles* of carbon and oils. If you're getting second-hand THC ("hotboxing" effect), it's the particles not the VOCs. You just need lots of particulate filtering CADR. Try getting an AirFanta 3Pro and setting it on 70% all the time. You might still smell it occasionally, but it shouldn't cause any psychoactive effects. Also, incense and candles and sprays are really bad for your health (almost comparable to cigarettes). https://dynomight.net/air/ --- EDIT: to the one who downvoted, please provide evidence of only cannabis VOCs causing second-hand intoxication. If I'm wrong I wanna know it, and I'll gladly fix it.

Oddly people forget "perfect is the enemy of good." 5500-2 or AirFanta 3Pro will be a massive step from nothing at all. If an open window isn't an option, exhale directly into the intake for maximum effect. Toke on buddy

AirFanta 3Pro, or just buy the filters and print up your own DIY [AirPhantom](/r/crboxes/comments/1oqinjr/3d_print_cr_box_for_airfanta_3pro_filters/) (I recommend PureWings 3 High Speed for the PC fans). Good CADR-per-decibel and CADR-per-euro, and it has infinitely variable fan speed.

Always a fan of the AirFanta 3Pro. Good for pulling out particles at low cost and low noise.

AirFanta 3Pro. As soon as you said "budget not a huge concern" the usual Medify / Alen / random $800 purifier sharks began circling, but for quiet yet powerful particle filtration it's hard to beat the 3Pro. https://housefresh.com/airfanta-3pro-review/

DIY CR box or AirFants 3Pro. You need a lot of airflow to do anything at all about dust, and these are the most economical options. For the CR box use 3M 1900 filters, four 20x25x1 or 20x30x1, get whatever's cheapest per square inch. BJs online usually has a good deal. Use the Airfanta if electricity prices are high in your area, because it uses a lot less energy. Cheapest price is on their website with code HOUSEFRESH, it should come to $152. Don't bother with the carbon version since it has lower particle performance and the carbon gets smelly long before the particle filter reaches end-of-life. https://cleanaircrew.org/box-fan-filters/ https://www.youtube.com/watch?v=IzxNaSP7c6I EDIT: ahh, I see you are in Italy? The Airfanta is probably the best option then, since in most of Europe 3M filters are only available through Digikey for higher unit prices, and generic substitutes tend to have many fewer pleats resulting in 2-3x smaller area of actual filter material. Instead of MERV 13 you might consider a CR box with the (European equivalent) M6 or F7 grade filters.

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.

So for portability, the AirFanta 3Pro would be your best bet. Running it on high sounds like you're torturing a computer, but its your best overall option on portability and efficiency. For the house, if you're only looking to filter out covid, its kind of hard because it takes X number of air changes (CADR) to effectively filter out the air, and that takes time relative to how fast and efficient your purifier is. You can't just plop a unit down and run it for 5 minutes then poof, the covid is gone. Also, I'd suggest running them in the home constantly, just to filter out allergens like dust and mold and whatnot. That way they're constantly on the hunt to filter the covid out and you can just move one over to wherever the "problem" is. If you have people at the house mask, especially strangers, it would eliminate a lot of these potential issues.

I'd bring an AirFanta 3Pro and run it on high for 30-45 minutes before unmasking just to get enough CADR to filter the air. I saw someone say they used RediMasks to stick to the air vents in an effort to filter the AC. Honestly thought that seemed pretty clever.
