@@blake27182 It was. Mila has great performance, but not it's price point is notably higher than many other brands / models with similar performance / coverage. Ultimately, we didn't include it because there are less expensive choices with the same performance.
@@deniselozada8829 In general, I've always found Dyson purifiers to be excellent. In terms of performance they almost always earn high marks. The biggest downside, and the primary reason Dyson didn't make the cut for this video, is they are 1) disproportionately expensive relative to their coverage (both the unit and the filters) and 2) more difficult to find for sale (in the last 3 years I've noted increasing out of stock issues across numerous retailers and even at Dyson.com).
same here, being allergic to dust is like being allergic to the world! I really need something to help! Did you end up buying one, and if so which one did you go for?
You are, without a doubt, my air purifier hero. I can not fathom the amount of wisdom that has been dropped in your air purifier series. You have single handedly made me the most knowledgeable about air purifiers out of anyone i know. You've done me a great service. You deserve a sub
By far the best and most concise video Ive seen regarding air purifiers. I’ve spent 3 full days reading analysis on air purifiers. This summed it all up. My head was spinning with info until your video! Thanks
Bought the Medify from your previous video review. Couldn’t be happier. My air is so much cleaner in my house (2800 sq ft). I used to wear breathe right strips at night to help breathing through nose. I haven’t need to wear once since I bought the Medify.
This video singlehandedly saved me so much time I have to give you YT algorithm love with some engagement here as a comment. Props for a well done, well filmed, well edited review video. Btw, do you have affiliate links to those air quality meters you were using? I'd like to test my home to help determine which of these might really impact things the best, and which rooms actually need help!
Thanks so much for your kind words, Lora :) I'm so glad to hear the video was helpful! This is the primary air quality meter we used to test purifiers - www.amazon.com/Temtop-LKC-1000S-Professional-Formaldehyde-Detector/dp/B0778WGMH2?tag=mc_1002-20
This is great! Thank you so much. I just got the Coway for my bedroom so I’m glad to se it on this list. It’s been running for about 30 minutes and I’m already impressed.
I bought the ma 112 because of your test, i thought I will take no auto mode for granted as long as it does its job. But happily surprised my 112 version got auto mode and also a light indicator with pollution level. It even has a pmi 2.5 value display.
You did such a great job on this review! I was happy to see you added AirDoctor in this video. We are remodeling an old house and there's LOTS of dust. We have an unexpected new baby in the mix so we have her in the only room that we got finished in the house which is the master bedroom. The room is about 350 sqft but has very high cathedral ceilings and a loft area. I was looking at the 500-100sq ft ones for that reason. Is there one you would recommend above the others? TIA!
Thanks, Sarah! I appreciate your kind words. With vaulted ceilings you'd ideally want a purifier with higher coverage (I'd say 3x your space to account for such high ceilings) and highest air flow. This would help get the vertical coverage you need and better manage the volume of the air. These would be my picks for your space: Medify MA-112 - geni.us/3unIMq (Amazon) IQAir HealthPro Plus - moderncastle.com/go/iqair-healthpro-series (IQAir.com) Oransi Mod - geni.us/fZlzs (Amazon) AirDoctor 5000 - moderncastle.com/go/airdoctor-5000
Unique question, what air purifier would work best get rid of Indian food kitchen smell in a new condo I just bought? Would they be equal for this purpose?
@gerrieshapiro2147 man, that’s a tough smell to get rid of. If the air filters aren’t working, you can do an ozone treatment but you might need a professional as ozone is hazardous.
Test methodology: I’d suggest making air quality measurements from multiple points in room. Suggest ceiling, floor and near intake of air conditioner or heating units, as well as near curtains. Of course air quality measurements next to filter will get the best results. Also compare it to what I would consider a baseline unit, which would be a box fan with Winix hepa and charcoal filters attached to the inlet.
This way by far the most detailed and helpful videos on air purifiers Ive watched this morning! Explained simply and concisely. Thank you so much. I just found out about all these allergies and didnt even know where to start. ❤
Just wondering for a home with multiple rooms, is it better to have 1 large unit or smaller multiple units to clean the air properly? Can the large units exchange the air in the individual far away rooms, for instance a 3 or 4 bedroom home?
Have you done testing on the effective range of air purifiers in different rooms? Does getting a unit capable of 2000 sq ft work for 1000 sq ft when separated into a few rooms?
We haven't done that type of testing except in a few specific cases (namely whole home purifiers / HVAC filters). There are many variables involved in this type of testing, including the unit, home layout, environment, doors / windows / building sealing, and more, such that it would be difficult to say anything definitive, in my view.
Using two Philips Air purifiers, the 2000i & 3000i & I'm impressed, my asthma has improved, dust build up on surfaces greatly reduced, can highly recommend these two.
You should really look at the Coway 300S/400S. IMO its one of the best at the cheapest price. It goes on sale too as well do the filters. I've has my 300S now going on for 4 years and its amazing with its dual sided filters it cleans the air quick.
If it's performance is anything like the other Coway I've tested I'm sure it's super impressive. Thanks for the suggestion. I'll see if we can get one for testing later this year.
@@Lou-xd9efcan’t dispute that. I have several IQAir and Coway purifiers. As a purifier junky, I believe those two manufacturers are the best. Rabbitair ( Coway ) is top notch as well.
I'm looking for a whole-house solution to place in the corner of a large area.. aside from noise, is there anything wrong with using a higher-square footage unit in a smaller area ? Do any of the usual-suspects of popular models ( airmega 400 , medify ma-112 , nuwave oxypure , etc) have a filter replacement indicator that is based the actual state of the filter, not just the time it's been on? I imagine, a non-smoking house, lots of plants, and no pets versus lots of cooking/frying, cigarette smoke filled house will cause the filters to be worn very differently after the same amount of on-time. I'm looking Looking for a whole-house solution..
Nothing wrong with that at all. A higher coverage unit in a smaller area means you can leave it on quieter settings and still get great performance. I don't know of any air purifier brand that uses a filter indicator based on filter state. I am not even sure how they would effectively determine that, assuming they would. Virtually all filter replacement indicators are simple timers.
One would expect the cost and coverage area to correlate, but they do not :D the Levoit Core 300S as an example is $150, but several other models with a much larger coverage area are cheaper, or the same price. I'm sure it would be hard to keep updated, but some kind of value chart would be good. I'm tempted to try out some of Medify's other models meant for smaller rooms given their price and the MA-112 being rated highly.
We do have an updated chart with pricing, coverage, and other metrics in a side by side here - moderncastle.com/best-air-purifier/ It's towards the top of the page.
We have the MA-40 with the h14 filters (and 9 cats) and so far it's been great. We keep the Medify in the main living space and actually have a core 300, not the S model, for the bedroom. This video has actually just been great to confirm my previous purchases lol
The problem is many air purifier companies do not correctly state the coverage area. It’s suppose to be calculated using the industry standard of 5 air exchanges per hour, but many companies do only 2 or even 1 air exchange an hour. This way they can claim it covers a larger area when in reality they’re just fudging the numbers.
Thank you for all your hard work! It is definitely appreciated! I especially appreciated that you let us see all the data in charts at the end! :) Which in home air sensor (similar to your’s) is the best value and most accurate-that you recommend? And where can we buy it? I battle serious health issues, so that would be invaluable to me! Do they test for mycotoxins? Thanks again!! 😊💕
Thanks so much for your kind words. Really glad to hear the video was helpful :) As far as home sensors go, I haven't really tested any...only 2, one of which I thought was pretty lame, and then the 2nd one is the one we use for testing, which is the Temtop LKC 100s. It's not too expensive and gets the job done. If you want to know exactly what's in your air I think it's a great choice for most. You can buy it here - www.amazon.com/Temtop-LKC-1000S-2nd-Professional-Formaldehyde/dp/B08DNJ8L55/ref=sr_1_4?tag=mc_1001-20&crid=10L52SUZ1CZ6O&keywords=temtop+lkc-1000s+&qid=1704003186&sprefix=temtop+lkc%2Caps%2C151&sr=8-4&th=1&geniuslink=true Regarding mycotoxins...these types of air quality meters aren't looking for specific contaminants in the air, instead, they are shining a laser that bounces off the particulates and back to the machine. So you'll be able to see all of the contaminates, but you won't know exactly what they are...only if they are there or not. A quick google search says mycotoxins can be as small as 0.1 microns, which is going to be below the threshold of the LKC, but they can be as large as 1 to 20 microns, in which case, you'll see all of those. The LKC will see everything from 0.25 microns and larger. So you might miss some, but you should be seeing the vast majority.
For small rooms, it seems you only recommend Levoit 300 but I'm debating between that and Blueair 411 auto as well and didn't notice that model in your opening video of all those purifiers. Curious what you think of that - leaning toward Blueair for the moment since seems to perform just as well but lower energy and looks better.
Blueair 411 is probably a good choice for small bedrooms. We haven't tested it yet, so it wasn't one we considered for this video. But the Blueair 211 we tested did fantastic and earned a recommendation. Blueair is a brand that I trust.
@@ModernCastle The Blueair 211 is great BUT the Pre-filter is a colored fabric that is on the OUTSIDE of the very nice metal structure..... I did not understand that and was mystified when I unboxed it. Once I watched a video that shows this I returned it immediately - why would I want something with all kinds of hair/particles clinging to a coloured cloth (black !!!) looking like I did not clean ? Static would be a potential problem constantly in the various types of particles being sucked onto it. So sad - they should have incorporated it inside the metal frame and I would have been a very happy camper. We live in rural circumstances with all kinds of bits and pieces floating about. Sad.
i see the word 'OBJECTIVELY' and not subjectively. Then I see a skinny man who looks like a person who knows about science and knows what he's doing. i click . Was not disappointed. sometimes a single video is worth 10 vids
Hi! New fan!! I have a question. I’m interested in the medify or the iqAir, it looks like medify is at the top of your list? Does it have a large 12 lb carbon filter like iqAir, and why isn’t iqair at the top of the list then? Also, I see that medify112 has a standard version and then an upgrade able version with UV light… what does the UV light do that the filters can’t already do? I have a big budget and price isn’t an issue, so I want to get the very best I can possibly get!! Thank you for answering both my questions!!! :) ❤
I do realize I’m speaking about the multiGas model specifically here which wasn’t in your test here. 😂 I just find the medify-112 so much more attractive for a modern residential home and it’s at the top of your list, so yeah thank you for clarifying if the carbon filter is sufficient for removing smells on Medify112
1. Medify does not have a large carbon filter 2. There isn't a "top" of this list. Every purifier in this video is at the top of their respective coverage category. IQAir GC MultiGas is $450 more than the IQAir HealthPro, while having equivalent particulate removal performance. While the 12 pounds of carbon is fantastic, that increase in price isn't worth it for most consumers. 3. UV lights inside are fine, but I wouldn't pay extra for it. If budget is no issue then the GC MultiGas is probably the best choice for you. Our full tests on that unit are here - moderncastle.com/iqair-gc-multigas-review/
@@ModernCastle though now that I started my research, found that Winix air purifiers, have different namings in European market, And there is not equivalent model to 5500-2, but there are equivalent to american models like AM 90. I wonder, if the pruifiers like AM 90 also have excellent quality?
@@wjbjnr1 Good question...but one I unfortunately can only guess at. I haven't tested the AM 90. However, in general, I have great confidence in the Winix great. I would think they are a safe bet regardless of the model.
Do you find 3rd party filters perform similarly to genuine filters? The price difference between an MA-112 genuine ($140) vs 3rd party ($60) is appealing but not sure if it's worth it. Also, this could be a future video idea. Performance of genuine vs 3rd party filters on top rated purifiers.
It's definitely something we need to test (thanks for the suggestion). I've only tested a handful of 3rd party filters. At least the few I've tested thus far have been great. My view right now is that, as long as it's still an actual HEPA filter then there really shouldn't be any issues. Some of these brands really jack up the price on these filters...so it's more than reasonable to think that a 3rd party brand could make a compatible HEPA filter for significantly less money.
I buy after market for my three air purifiers HEPA and carbon both have been excellent. I but the least expensive with decent reviews on amazon. Only issue is some companies fold the carbon filters and I can never get them flat after that. My suggestion is read reviews first to see if they fold the filters also maybe able to tell in the photos from customers. I'm sure they fold them for cheap shipping but if you can't get them flat then dirt can get behind them after install.
Late to the game here, but I'm looking into buying my first unit. As to the cost of replacement filters, OEM filters are expensive. I had the same thoughts as you. However, I think they get you (the manufacturer) by saying the Limited Lifetime Warranty is only good IF you use OEM filters. I would expect that they would want proof that you purchased OEM filters should you ever need warranty work. Don't quote me on that, but I fear that is how it would work.
Happy to see results of testing, but the gigantic variability of particles in the air is concerning. The Blueair 211+ only had half the work to do of others, as example. Doesn't seem to be fair/reliable data.
In our 2024 version of this video (which is coming soon...just waiting on my editor to finish it up) we have all new updated testing with more consistent baseline starts for every test.
Thank you! We finally got a chance to test IQAir this past year...very impressive across the board. Expensive, but impressive. Hoping we can get an Austin Air this year for testing.
Hello! Love this review and thank you for your time I have the Oransi the big one I like it but I don’t love it you think Medify is better then Oransi I just need one for two open rooms thank you 🙏🏼
This video was awesome. I just wish it had that massive chart that showed all the models and how expensive they were and if they had a carbon filter, app connectivity, square ft, etc. Just the much more in depth comparison chart of all the details of the tested models put on one chart to make it easier to decide between them.
This video is amazing! Thank you. What would you suggest for a space (1 floor of home) that is 1170 sq feet and 9’ ceilings? Or do you think it’s more important to do the family room and kitchen only as it’s the most used area? This would be 736 sq feet with 9’ ceilings.
I'd go with one of the higher air flow units to make sure you're getting fully coverage (given the volume of space is more than many homes with those 9' ceilings). AirDoctor would be my first pick, but the others are fantastic as well. Buy AirDoctor 5000 / 5500 - moderncastle.com/go/airdoctor-5000 (AirDoctor.com) Buy Medify MA-112 - geni.us/3unIMq (Amazon) Buy Oransi Mod - geni.us/fZlzs (Amazon) Buy Rabbit Air A3 - geni.us/uhXbxS (Amazon)
Currently have a Healthway Deluxe Air Purifier but haven’t been able to get filters for it in months. We got it because it’s supposed to be “hospital grade“ but in need of an air purifier to take its place while we wait on filters. What do you recommend for an air purifier that removes pollen, pet dander, etc but capable of large areas? Not concerned about price if it works well. Thanks for the video and thanks in advance for your insight.
For what you're looking for I'd say AirDoctor 5500. See here - moderncastle.com/go/airdoctor-5500 2,000 sq. ft. coverage area (2 air changes per hour) and essentially perfect purification performance.
I just use a carbon scrubber with a hepa sleeve. It's like 60 dollars, 30 dollar replacement filters every 6 months. This thing pumps. I have 3 smokers in my house and you'd never know it unless you saw them. Life hack: if you have central air, first get a good filter for it but second if you your air filter very close to it, it pumps that air throughout the house for free multiplying the effectiveness of your air filter.
Have you done testing reviews on the HEPA filters? Trying to figure out why there are such drastic price differences for filters that fit the same purifier.
Not sure what you mean by that. Virtually every single filter in this video and probably 95% of every air purifier and filter we've ever tested is HEPA.
Would love to see an odor removal duration comparison. I've tried several filters in the Levoit core 300: 2 stock, one OEM "green" toxin remover and a generic 3rd party, on a nasty pet odor, None were able to last 24 full hours. Additionally the OEM Levoit filters have prop65 a warning printed on the boxes that they cause exposure to lead and BPA. The 3rd party has no such warning.. hopefully it's not simply omitted. In the end I resorted to burning candles to get rid of the smell, and the filter to remove the smoke from the candles.
Unfortunately, Amazon won't let us list prices since they often change (and vary from country to country). Thank you for your kind words. Glad to hear the video was helpful!
Thank you for putting this together! I saw that the Dyson air purifiers were in the air purifier group outside but it’s not on the list of those tested. Do Dyson filter not work well?
They do work well, as well as many on this list. However, their price point relative to so many others just no longer makes sense. You pay quite a bit more from Dyson, but you aren't getting more. For this reason, we excluded them from our 2023 list.
Would like to see how a DIY Corsi-Rosenthal box stacks up against all of these. I just made one with a $20 box fan and 4 MERV-13 filters. Ive seen tests where they are beating out almost every HEPA because of the high CADR, but I havent seen it compared to a comprehensive list. Usually its like 4 or 5 different things being tested. Even just slapping a single filter to the back of a box fan seems to beat out most of the low end HEPA filters it seems.
How do these same filters continue to perform after extended use. I know some filters after awhile such as 8 weeks. Will start leeching particals out or the seal fails from what ive read. So basically im looking for long term testing.
Amazing research! What air purifier comes to mind if you're looking for one for a bedroom that also works well as a white noise machine for sleep. So a purifier that has a nice consistent deep sound to it and you can manually change the fan speed.
Thank you the robust information, I appreciate all your work! Bought the levoit and winnix air purifiers for my home based on your reviews. Have you tested any portable air purifiers? Specifically, something that would work in a car? I am thinking of getting one for a family member who is a travelling salesperson for a chemical company - would need a feature to filter out any harmful effects from riding in the car with merchandise.
Unfortunately, we have not tested any portable air purifiers. The smallest unit we've tested is the IQ Air Atem - moderncastle.com/air-purifiers/iqair-atem-review/
We did not specifically test dander, so I cannot say. That said, there is no reason to think airborne dander would be substantially different than any other airborne particulate.

Thank you! We are actually in the process of testing Shark's purifiers. Here is our first review - moderncastle.com/shark-3-in-1-air-purifier-review/ - this unit is good, but not quite good enough to make our best of list. However, the max version of this model was more impressive. It would meet the criteria of our best air purifiers 2023 list (we cannot update the video as easily, but there's a good chance we'll add it to our contextual best of page). I am going to have that review published to our website next week.
As an avid and active hobbyist, I don't see any data on VOCs, specifically for my needs VOCs from 3D printing, both FDM and resins. Am I missing it, or is the data in some other measurements with which I am not familiar?
VOCs are just incredibly hard to reliably test. I have a couple of VOC meters that we've tried and neither are reliable enough that I feel good publishing the data. The higher end VOC measuring devices would likely be better, but we just don't have the budget for those, unfortunately.
So weird to see that none of these are available in Europe. And all the ones available in Eurooe is not on this list... Missing Brands are: Electrolux Philips Blieair Smartini Coway Woods Xiaomi
Indeed - surprising there isn't more overlap between US and Europe. Coway actually is on our list though. The Coway 1512HH, great for medium coverage rooms. Xiaomi is another one we've tested. However, the performance just wasn't good enough to earn it a spot on our list.
1. Dyson air purifiers have become increasingly difficult to find at major retailers and even in stock at Dyson.com over the last 2 years 2. New air purifiers I've tested in Dyson's category simply offer the same / better performance for less money for the unit and for the filters Dyson purifiers are still excellent machines and perform well, provided you can find one for purchase. But you will definitely pay a premium for the Dyson name. While that premium is worth it when it comes to vacuum cleaners, Dyson's performance isn't any better than numerous other high performance air purifier brands in 2023.
Great video. My house is against the freeway wall. My thermostat says poor IAQ. Once I open the windows and get fresh air in the IAQ starts to improve. I want to monitor this closely, would you recommend the Temtop LKC-1000S+ 2nd Gen?
I bought a 1000 square foot home. Built in 1953. After purchase the neighbor shared that 10 years ago the basement had flooded. The basement had tiles that I pulled up a year ago. Walls and floor cement. I've only ever noticed a 10 inch circled area on stairwell ceiling before I moved in. In which I treated and sealed with kill then painted. What would you suggest for my area?
Any air purifier on this list is going to help. I would recommend the one that is appropriately sized to your basements needs. Probably something in the mid sized coverage: 500-1,000 Square Feet Coverage Buy Hathaspace HSP001 - geni.us/xddy (Amazon) Buy AirDoctor AD3000 - moderncastle.com/go/airdoctor-3000 (AirDoctorPro.com) Buy BlueAir Pure 211+ - geni.us/BCqi5D (Amazon) In addition, if your basement is prone to moisture / water you might consider a dehumidifier.
Hey Derek, in terms of third party filter replacements. What are your recommendations when searching for whatever filter one would need? How do we guarantee that we are getting a true hepa replacement for our model of Purifier?
Unfortunately, I haven't tested many 3rd party filters. As far as how to guarantee it's a HEPA...buy from a reputable brand, be it 1st party brand or a 3rd party. Beyond that, looking for the specific HEPA rating on the product page can help as well.
Exactly Dyson's air purifiers are all excellent and high performance machines. However, they aren't any more high performance than numerous other brands that are 1) more available with 2) a lower cost and 3) less expensive replacement filters. There is just no compelling argument to buy Dyson over other purifier brands.
Hi there, thank you for this extremely helpful information! I am trying to decide between one AirDoctor 5500 or one AD 5500 AND an AD3000. Our home has two floors. Mostly open concept on 1st floor minus the main bedroom. We have vaulted ceilings and an open loft area between 1st and 2nd floor. Would you buy just the 5500 or both? Thank you!!
With 2 floors I think you'll be happier with both...especially given the vaulted ceilings. That ends up being a lot of air volume for a single unit (even one as high air flow as the AD5000) to get through on its own. The additional AD3000 will make a big impact.
I have a 1,000 sqr. Feet apartment. Do I need an air purifiers in each room if the doors are shut or 1 air purifier rated for 1000 plus is enough to take care of the whole apartment?
I have the IQAir HealthPro Plus and whenever I run it, it puts a strange smell in the air. It really bothers me. It’s always done this, even when the filters are freshly changed. Are there any air filters that don’t emit any smells?
What you're smelling is the carbon filter. If you don't want that smell just remove the carbon filters. However, it's the carbon filters that are removing VOCs and odors from the air...so it's a bit of a catch 22.
For a small medium room (carpet) What would you your first and second choice? 1.Blueair 3410 (aud 450 dollars) 2.

Winix Zero+ Pro 5 Stage (aud 365 dollars) I've been doing so much research for days but cannot decide it on my own. Thanks so much :)
Hello! Many thanks for your reviews, they are awesome! I watched a few about air purifiers and i am looking for a one for our car. The one you suggested for a small room is still big enough for a car. I feel that in the category 'the size matters' and the bigger ones should deliver a better result, but still... Can you advise on this? Not too big but efficient enough to deal with sand storms, 50C heat (melting plastic), CO2 and cigarette smoke? Thanks a ton in advance!!!
I'd go with the Levoit Core 300 - www.amazon.com/LEVOIT-Core-300S-Air-Purifier/dp/B08L73QL1V?tag=mc_1002-20 It's got more than enough coverage for a car, while still being small enough that it won't take up a ton of space. There's no need to go any bigger than this for a car.
Just set up an airthings wave in my home to check radon levels. Turns out my CO2 levels are through the roof. Im going to buy the Oransi Mod in hopes it helps, thanks for the recommendation. (IQ Air is too high of a price tag.)
When you rated the Medify as having 0 Ozone detection, was that WITH or WITHOUT the ionizer being used? Should I be concerned while using the Ionizer option regarding ozone in the air?
@@ModernCastle WOW thank you for the reply! Would you say that the ionizer should be of concern ? I've been reading that it causes Ozone levels in the air, but I would love your opinion
@@flpacor8812 In our ozone tests it read 0.0 parts per million. Our meter has a resolution of 0.1 PPM. So there is a chance there is some level of ozone being created, but it's within safe limits according to US government agency regulations. If you are worried at all just turn it off. It will not have a major impact on performance.
Hi, the listed models aren’t avaible in my country but an expensive Dyson isn’t my dream but truly want to know your opinion on SAMSUNG models because of your very detailed reviews.
We haven't tested any Samsung models, so I can only guess as to their performance. However, given my experience with other Samsung products over the years + our tests of Samsung's robot vacuums and cordless vacuums, I would expect strong performance from any Samsung air purifier.
did the medify clear the place significantly faster than the other large rooms ones? 5000 square feet for the fact it has similar specs to the others seems potentially exaggerated
Hey! I'm a teenager who's bedroom is currently in the basement... There is absolutely zero ventilation in my room and I don't have a job so I will not be able to replace the filters. Can you please recommend an air purifier that will be sufficient for a small bedroom with completely permanent filters?
@@stayed9694 Airdog is the only brand with washable filters that I've tested that has reasonably good performance. They aren't as good as any purifier listed in this video, but the filters are washable. See our tests here: moderncastle.com/airdog-x3-review/ moderncastle.com/airdog-pro-review/
Out of all of your reviewed air purifiers, would you recommend Medify or Rabbit Air for longevity? I am only leaning towards the Rabbit Air since they have a less conditional warranty and cheaper replacement filters.
It really is a total toss up between those two. I have great confidence in both brands. I would personally lean a little more towards Medify as they were the stronger performing brand in terms of purification performance.
The before is the particulate level before we started testing. After is the level after the testing is complete. Same for PM10. Same for AQI. CADR, the Clean Air Delivery Rate, is a metric that was developed as a way of measuring the performance of residential air purifiers. The CADR rating reflects the volume of air in CFM (cubic feet per minute) that is cleaned of particles of certain sizes.
@@StormySky48 Using a nationwide network of monitoring sites, EPA has developed ambient air quality trends for particle pollution, also called Particulate Matter (PM). PM2.5 describes fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. PM10 are particulates 10 micrometers. The Air Quality Index (AQI) is used for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air.
Thanks for the video! I'm looking for an air purifier for our bedroom. What are your thoughts on the Rabbit Air model SPA-700a. I can get a "like new" used one for $200....worth it? Or should I go with a new, cheaper option from Amazon?
That's a pretty good deal if it really is "like new". We tested that model several years ago. Our data / tests are here - moderncastle.com/rabbit-air-minusa2-review/
How far was the noise level from the device? The position of the decibel meter in relation to the sound output also influences the result of the sound noise level.
About 3 feet away. The position, distance, and angle of the sound meter relative to the air purifier is as close to identical from test to test as we're able to make it.
In our tests, its ozone did not exceed 0.0 PPM, putting it well within US Federal safe limits. The fact it didn't have a HEPA filter didn't impact it's performance in terms of air quality improvement. Our score is primarily based on air quality improvement and not the type of filter.
If the noise level is bad, can you just put it in your basement even if you have a 2 story house? Or do they have to be centrally positioned in a house?
It will have some impact on your air in the upper stories, but in general, you want the air purifier to be closet to the rooms you want the most purified air in.
Any advice for good air purifiers , we live in Southern California very close to desert with a lot of dust. Looking for medium and small bedroom.Keep up to excellent work
