Is an $800 purifier best to clean your home's air? We lab tested 5 top brands 

I came to the comments for this. Thank you!

@@Charmingpreppylife he’s wrong though. He might have meant to say “the purifiers with the highest CADR are...” but what’s actually BEST depends on what people need, and obviously we don’t all need the highest CADR.

The Levoit they used was literally Levoit's shittiest model, meant to sit on a desk next to someone because it only reaches 1 foot around it, it is not not even meant to do an entire room. It doesn't even have a carbon filter. Dyson has no excuse that is $800. The $250 Levoit model is much better. I went from anaphylaxis from airborne allergens to no incidents since I have had it. It is unfair they used the shittiest model to tarnish their reputation. That model was $60 before the pandemic too, I know because I considered it and decided to get one with an actual HEPA filter instead. This Marketplace was extremely misleading and full of misinformation. I am actually extremely disappointed in them for this poor research. They didn't even mention the difference between filter types and how they work. It was such lazy work.

Thank you!

@@Pollencakes It's insane, that this filter was only 60$ before and I assume dyson always was about 800$.

exactly. Now we know why companies don't talk with CBC News, they cut their full explanations into tiny sentences.

I think you're right. All they went on about, and rebutted by Dyson was the CADR metric. So it can filter out X amount of air but now how effective it was afterwards. I'm sure if you grabbed a faster flowing box fan and strapped the same furnace filter to it, it too would push out even higher CADR numbers. That filter can/is only filtering so much before it is full/clogged and it's CADR number will significantly drop (but will actually filter better). In the PHD's test lab, they measured the volume of air that was able to be filtered. What about information on PPM of the incense smoke after say 1, 2 hours for each filter? Wouldn't that tell you how effective the filter was?

@@maxwellkeeling3781 Exactly, there is a LOT to filtering air and movement, I learned this with carbon scrubbers air filters and sizes and speed and a lot of research. It's more than people think. Move the air too fast and it doesn't get a chance to be filtered through the carbon, it flows "over/past it". Too slow though and it is not effective enough, like they said. There is a "sweet spot" where you get a balance of both effective filtering and air movement. And yeah, as filters get clogged the airspeed will drop, but the filtering goes up. This is what they found with masks and Covid. That extended mask usage, while not good ultimately, was good up to a point in the sense that the filtering efficacy went up with them. Simple cotton jumped almost 10% higher the longer you wore it. Moisture buildup from breathing is likely what was narrowing the tiny openings and making it filter a bit better. Of course the tipping point the other way, isn't far behind (so dirty it needs cleaning or discarding), but there again is that sweet spot where it's great. It's a finite thing, a delicate balancing act. Same with cars, efficiency and durability and power. You gotta be insanely efficient nowadays, but also have performance and longevity too, you have to split down the middle somewhere and find the happy medium between all of them.

Considering the price point of their devices, they're almost OBLIGATED to release some kind of statement ...

@@kizersosei4919 agreed

Yes and no. HEPA filter is not the only filter used in air purifiers. A lot of them have carbon filters as well, those get rid of smells and chemicals (HEPA gets rid of only particles). Dyson has a rather thick carbon filter with a lot of carbon granules Blueair has a thin sponge with a bit of carbon inside, so technically they both can say "we have carbon filtration" but their performance and longevity will be different. The other part why Dyson is so expensive is their bladeless fan technology (the filter doubles as a cool and hot air fan), and a ton of sensors and smart technology bits and bots (you can get air quality reading, control purifier from the app, set timer etc). So yes for getting rid of particles alone, big fan, big HEPA filter, thats all you need, and that blueair 211/221 is perfect for it. If you want to get rid of particles and smells look for a purifier with a carbon filter full of granules, not the sponge ones. The other stuff like air quality sensors, auto mode and smart device functionality depends on your preference. For example blueair has auto-start so you can use a a smart electric socket or a socket with a timer to make it work on a schedule or control it via app. BTW. Carbon filters are dirt cheap and easy to made, so it is disgrace that there aren't that many air purifiers with decent carbon filters!

Saing that Dyson is blade less fan is misleading. inside there is regular fan. This fan just redirect the air steam in some "fancy" and vey inefficient way. Beside the form and high price there is nothing good about this fan.

@@miroslawkaras7710 I agree on this. The name is silly. Still it is their patented technology and they are selling those "bladeles" fans for high price. So it's natural that they ask pretty penny for having it on air purifier. Not many purifiers doubles as fans so there is some value there. I'm not fan boying for Dyson, I just didn't like how they pounced on Dyson in this report. They simply sell a premium product with different features. Personally I wouldn't buy it, but dog piling on them because they do not filter as fast as other air purifiers is a bit weird.

@@pingwingugu5 At the same price, you can get Austin Air Purifier that contains 12 lbs of activated carbons. Dyson is only good when you use all of its functions - heat, fan, and purifier. Otherwise, you will be better off buying them separately.

@@GBR9794 if you can fit 3 separate devices in your flat then sure ;-)

Thank you hero

You are the best ! ❤️

10:04 what is CADR

❤

Was that guy even a representative? He looks like the actual engineer.

Right? The guy made good points and I respect Dyson more for it now.

Kudos to Dyson. She kinda annoyed me when he said purifying wasn't the main metric and she says researches says it is. Clearly he was saying purifying the air was a bonus feature on their fan+heater.

Exactement 💪🤣

@@BrickMediaStudios Even more kudos, sent the person who knows the product inside out, not someone who is there to read lines

So true

He was dodging the question though; I did not hear what other important metrics they are focusing on instead of CADR and why...

@@jinwang562 I find this video less informing because other big important issues are , how loud is the machine? Dyson is the best for that for example due to its efficient motor. Other than that how much power it needs to run at that CADR. I was expecting a bit more data than just cadr

@@jinwang562 he wasn’t dodging they edited that interview. He’s right that just using that one metric is not a fair representation of the field. They also have fans that just do air purification without the heat function etc that would have made for a much better comparison.

@@ucyberwolf It really doesn’t make sense why they decided to not use the model that only does air purification. It is cheaper than the one they tested and it is designed for larger airflow. It’s misleading at best and I question if it was intentional to make this more sensationalized. Poor test, you could have done much better.

not me , he is a sham , Dyson is for fools.

Excellent points like what?

@@x-0-x-0 rate of clean air flow is not the only metric. Stuff like design, longevity, energy consumption and technology matter too.

You respect a company that is outrageously overpriced and has the worst performance of cleaning the air with their air purifier? SO you respect fraudsters?

@@honprarules that's ridiculous. They were measuring how much the air cleaners filter the air you breathe. Longevity, energy consumption was irrelevant. The technology matters the most - the technology of an air cleaner needs to be good enough to clean the air! The Dyson was terrible.

This is true.

the bible says God created the Earth in 7 days. Therefore it is true.

thanks dyson marketing troll

That's probably because they can't actually make any solid claims about the quality of their products.

You mean Dyson salespeople don't carry sidearms?

Air quality guy really should have checked for radon. But I suppose that, for this show, it's irrelevant. You don't fix radon with air purifiers.

radon is a silent killer

Radon is not rad

@@contournut5726 how do you eliminate radon?

@@grod805 Radon is naturally occurring in soil and can enter a home through its foundation. Usually radon levels are higher in parts of the house closest to the ground such as basements. Typically, it is eliminated by venting air from under the foundation to the outdoors. This is done by installing a pipe that extends from under the foundation to outside the house, and installing an appropriate fan that draws this air outdoors.

Alto they don't mention that they used a fan to agitate the air at 11:23

Agreed my friend, I believe they didn't want to completely destroy the old lady on the show about her serious mold problem, so I'm assuming that guy took her aside and warned her of the very problematic mold that she needs to get rid of. She willingly volunteered obviously, so they probably gave her that much.

Literally. These test they ran halfway mean nothing. Wouldn’t even give it an 8, prolly closer to a 6

Exactly what I was thinking. Its not an apple to apple comparison. They should test the purifiers based on thier capacity rating

I really don't understand your reasonning nor any of the answerer's. The metric given is in m3/hr. It doesn't deppend on the size of the room. A 60m3/hr purifier would clean up a 60m3 room in an hour but a 120m3/hour would do so in half the time. Or am i missing something ?

it doesn't heat... but okay

@@seansapir1 it literally does

You can buy a compact space heater for $20

100%. I bought this mainly for the heating option. I got a bonus cooler and purifier with it. 👍 I can't complain about that. Plus it looks way cooler.

One cannot argue with someone that bought the product as they will take it as a personal offense unfortunately 🤥🙄

Also how loud it is and how much power it uses.

Agreed. It has been impossible to find replacement prefilters like the one in the Honeywell I spent hundreds of dollars on.

I get my filters on amazon great pricing for half the price

@@CheapSushi true, the dyson uses 2250 Watts power!

@@pmabrouk I have a thirty year old honeywell true hepa. I found new old stock filters and pre filters on ebay.

Now we know why companies don't talk with CBC News, they cut their full explanations into tiny sentences.

marketplace always does this, to make their original premise appear to work. They love bashing any popular product with their own limited "tests". Cant stand this show for that reason, but i was curious to see if they had cleaned up their act any. NOPE.

It doesn't appear edited, and it seems pretty in line with Dyson products: Style at the expense of some functionality.

Aren't plums supposed to be ripe?

Lol

I this just has to do with the type of filters in them

They said it doesn’t even matter how good the filter is if it would not even pass through the filter due to low airflow

CADR is a measure for the clean air output. It considers both air flow and filter efficiency.

Those carbon filters are more gimmick than actually helpful. Yes, they can remove gases, but not for very long. Unless you are changing them out very frequently .... it's snake oil.

@@financialchimes4546 except clean air means different to different companies. I can't ever consider a purifier with no UVC for killing germs should be considered giving out "clean air". On top of that the more layers filters being present obviously drastically drops CADR. The blueair ones don't have all the filters hence the CADR is high. By that logic, the lower CADR would be better lol. The entire metric is ultra bogus gimmick to start with.

Lol that's my prof and he tells and energy related pun before every lecture

Batman

Yeah He came out of the same mold as bernie sanders.

he looks like a Bruce Banner

Exactly! They were just measuring air flow. Maybe they got better air flow in the model with the fan taped to the filter because the air wasn't properly passing through the filter. Lol it looks like they literally put it together with masking tape.

Exactly what I was thinking. They just measuring the volume of the air. Obviously the bigger the fan, the bigger the airflow generally speaking

They also use a fan to agitate the air in the test room 11:23, but they never mention anything about it ;), guess why.

Exactly what I thought. They compared 800$ with 99$ as well .

@@donaldcooper3156 the were all compared in the exact same size room

@@monkeyoperator1360 Its like comparing fiat punto and a train how which can move more people.

After watching this video, which one you’re going to buy ?

what type of levoit? vital 100 or P350?

yeah I love my levoit

Exactly. I think he mentioned air "projection" at some point. CADR doesn't measure that. It's too bad he didn't have more time to touch on the subject

If the purifier blows the cleaned air in a different direction from which it is pulling from, it is in effect, circulating the air in the room. Blue Air has the highest CADR and uses this design in all of its models.

@@WHERESSS Have you experienced the air projection from most air purifiers? They project at a very low velocity. That air doesn't travel far before being recirculated through the purifier.

@@meboz67 Yes. Blue Air fans are strong. That's what the CADR is, effectively. Without a strong fan with high airflow it is impossible to achieve a high CADR.

much cheaper to by a fan plus BlueAir

Yes that why I’m saying they all for different room size

The blueair 211+ they tested in this video doesn't use hepa. In fact none of blueair's products use true hepa filters.

Not only that. The Blueair model they tested was a large room air purifier. Many of the others were not. It is interesting they compare the tiny Levoit LVH132 "Personal" desk purifier against the other larger units. They could have at least used the Levoit LV-PUR131 or Core 600S. While they are at it they should of had the popular Winix 5500-2 in there. All of those units have a separate activated charcoal filter for harmful fumes and also have a true HEPA filter. I swear this test must have been ran by Blueair

@@nano411 you're spreading misinformation. Classic series and above use true hepa filters. To the OP, HEPA Silent is only defined by noise(fan speed), not filtration capabilities. HEPA is a standard for the filter, not fan speed. In any case, HEPA Silent doesn't mean anything. It's just a low setting for the fan. The Blue Air Classic and above are are true HEPA filters.

@@nano411 that is true, I’m not sure how much it matters though. I use levoit myself, but blue air proprietary filter tech is quite good, it’s been independently tested and shown as such. Hepa is a proven technology that gives a great deal of comfort as a marketing term as if your filter is hepa certified and has good cadr, you know it works. Blue airs proprietary tech is quieter and does consume significantly less power. I suspect off The shelf hepa tech did not meet their requirements for power or noise levels.

Well then with her big teacher pension she should easily be able to pay for the furnace filter upgrade. But it makes me wonder if the furnace is ever maintained, if it is why wouldn't the HVAC technician bring this to her attention.

@@sherwoodcosmohealthcare1694 thats ironic

Right after he said that, I was like....what if you use Brita filter water instead of tap? 🤔🤔 Not everyone can afford to buy distilled water to constantly refill their humidifier

Update: Emailed the expert and unfortunately Brita doesn't do much in terms of getting rid of minerals/particles for usage in a humidifier.

Dissolved minerals would need an ion exchanger, not a filter.

@@knd44 you could buy a stovetop distillation apparatus - a still - and make your own. Then use it to make some liquor to recoup what you spent on it!

@Andrew Demchyshyn I found his claim to be somewhat agitating. It appears he was using an ultrasonic humidifier with tap water. Ultrasonic humidifiers are supposed to be used with distilled water which will have little to no particulates. There are other humidifier types on the market. Additionally, the amount of particulates in the air when measured immediately beside an improperly used ultrasonic humidifier do not necessarily represent the amount of particulates which will be suspended and stay in the air. It's much more complicated than he stated. Edit: My @ didn't work for whatever reason.

How much was yours? Saw it going for $390 online @best buy, but I imagine it was going for less pre-covid

@@jpdelete I got the Blueair 411 from Home Depot for under $150. It's the smaller version for small to medium size rooms. Definitely would recommend!

@@Vv_li has it made a difference for you? I have allergies so I'd love to be sure.

I tried researching the Molekule some time back. I just recently tested an Alen 45i purifier. The Molekule distinguishes itself with the use of UV technology. The second expert with the glasses said that UV technology is not worth it. He said that the amount of UV used is too low to be effective.

One of them lived in an apartment but yeah air quality is really bad in apartment buildings, even more so if they have laundry facilities, are pet friendly and allow smokers indoors.

Especially with neighbors who live in same building and smoke cigarettes several times a day and it's obvious someone is smoking near the front gate and it blows to our apartment in the back of the building (my neighbors are usually seen smoking outside on their porch or our outdoor entrance area facing the street) Edit: I am in the west coast of US

Came to the comments for this! LOL

Yeah, they should have test it in s small room and see if it was effective rather than testinh it in large room.

Lmao

she knew it was the most expensive

A tray of water would be a better choice at a low cost of entry. With near zero chance eof failure unless you flip it over.

@@lot10101 I can evaporate 3+ gallons per day with a humidifier. A tray of water isn't going to get the job done. If you are too cheap to get a humidifier, use a bucket as a reservoir, hang a towel dangling into the bucket, and use a box fan to blow over the towel. You need surface area and air flow to evaporate a lot of water. You can even get the box fan to pull double duty and strap a filter on it to filter your air at the same time!

A bucket of water with an aquarium heater works well too

That's why they said use distilled water or a steam humidifier

@@andrew20146 lol... I live in the tropics and have no need for a humidifier. Interesting that you know me better than me.

I'm wondering if they tested it in a to large of a room. By the looks of it in the video it might have been to big of a space.

@@XDonlyone Yeah as much as it was an informative segment, I feel that the machines got a bad rap for being "underpowered". For the expensive Dyson I can understand the disappointment; but the cheaper, smaller units aren't designed for anything other than small bedrooms, which is what I use mine for. You don't need 500+CFM for a bedroom.

@@DABlinxz i bought the Levoit H13 a few months ago for my bedroom and I no longer wake up congested and I don't know how to explain it but the air just feels light and clean to breath in. So it's working more then fine for me.

@@XDonlyone I'm saving a fortune in sinus medicine.

Yep, I've been doing this since University of Michigan released a video about it like 9 years ago, and same thing and my only complaint has always been the noise. Also: quick tip make sure to check the corners of your fan! hold some toilet paper to the corners, you'll see they're actually sucking in! Put some tape over it to fix it. I try to tell everyone who does the filter-technique this!

While I don't disagree, I think the comparisons are all very valid. I think, instead of being compared to raw CADR, however, I think the MORE valuable measurement would CADR/Dollar

@@mr.bennett108 im not saying the tests werent valid. I just wish they had chosen models that were more in competition with each other to make things more fair. Right now its like having a civic, corolla and bmw 335 going up against each other to see which is the better driving car.

Yep pretty much. Also Dyson have a naturally low CADR due to its design

Not to mention they didn't test for VOCs which HEPA only filters will not filter. Dyson was entirely correct that CADR while important isn't the only metric, additionally a finer filter that filters smaller particles will have more resistance for any given surface area. They didn't strap a HEPA filter to the box fan so the measured CADR is immediately not comparable to any of the other air filters (though the filter used was still good enough to trap most allergens like pollen and dander.) Additionally they did not disclose the efficacy in reducing the particle counts, what good is a high CADR if the filter is 70% efficient vs 90% efficient on a model with lower CADR. There's too much nuance into what makes a good filter to cram into a 20 min video that needs to tell a story. I feel marketplace's quality has been on a sharp decline for years in their chasing of broader audiences by americanising the editing style and removing all semblance of actual information and quantifiable testing.

Did Dave from Dyson give you the rest of his explanations that they probably edited out? Because what you've said sounds pretty much like an elaboration of his "we don't think that the measure of air purifying capacity is the only thing that's important when it comes to appraising air purifying capacity" line. To be clear, I'm not necessarily disagreeing with you or Dave, because nothing can ever be distilled down into a single all-encompasing number without at least partially sacrificing nuance or compromising situational variance, but the underlying issue that this piece was trying to highlight is that customer expectations in regards to these air filters are not necessarily matching up with developer intentions (if we're assuming good faith rather than corporate greed), which among other reasons seems be greatly influenced by imprecise and uninformative product claims on the box or in ads. This mismatch between company and consumer is a fault and responsibility of the company, not the consumer, who should be provided with adequate and relevant information about the product and its expected use cases so that they can compare the product with others and thereby make a decision. It's all well and good for Dave to encourage customers to do their own research, particularly for a company like Dyson whose products are priced more than high enough that most of their customers are probably capable of actually conducting such research or have enough money that they don't actually care. But a great many consumers are not actually capable of successfully undertaking the kinds of product research that Dave and many other companies seem to expect (or hide behind), which is why we have consumer protection laws that place the responsibility for researching and communicating information about a given product onto the company, not the consumer, or that at least prevent companies from making claims or representations that they can't reliably demonstrate. Like, I'm sure that the legal department at Dyson and all those other companies have scrutinised every word of those product claims and ensured that none of it actually breaches the letter of the law regarding what claims they can and can't make, or how they must represent them, but based on this video it seems like many of these companies are less interested with actually helping their customers make informed decisions about their products (which you'd hope they trust enough to be appealing when portrayed truthfully and saliently) and more interested in telling customers (or not telling them) whatever is necessary and legal in order to goad them into buying the product. Obviously, I don't naively believe that this practice is limited to the air filtration industry or that it's a remotely new practice, but it's still disappointing to see nonetheless.

thanks for your detailed response. Very good critique!

The reason they don’t test it is because hepa is hepa, it’s already a known quantity. So cadr really is the only difference, other then looks and features. Levoit sells specific filters for VOC/PET/Standard Hepa, there are very few differences between hepa filters

I can say you are wrong - for most people, the CADR is the most important. Without enough flow rate, you air are not get cleaned it should be.

It's still not a good air purifier

Yea, me too. I was waiting to get more in depth details on other VOCs.

It came in handy during a power outage that lasted a few days in winter and ran perfectly on a back up generator

Me as well and i smoke in the room from a bong and it cleans that smoke quick

A heater that heats. What'll they think of next! The problem for Dyson is their tiny little fans are very poor at shifting air.

Got the same one, and seeing how well it works i think it really is unfair to just take count of the CADR

they fooled everyone, the reportage is highly misleading, they used another fan to agitate the the air in the test room and they never explained how the test was performed. 11:23, you've been fooled.

Also if you have mould issues it is a good chance you need a de humidifier

What about cool mist humidifier?

Electrostatic = ionizer, very controversial if negative ions helps or hinders your health. I got the 211+ Auto today but I wish I did more research on this. Customer service at Blueair does not seem to professional so far. The Blueair is CARB certified.

I would go got MERV 10+

good tip!

Thanks for the tip!!

Yeah it’s hard to take this completely as is because anyone who lives in a cold place would know how much better it is to have higher humidity in the winter especially when sleeping

you've been fooled they use another fan to agitate the air in the test room, 11:23

I have the Dyson pure cool desk fan (DP04). It's a great purifier. Highly recommend. It has a higher flow rate than the HP04 pictured in this video. But like the Dyson engineer said, CADR is only one metric of many. I got my purifier for my dog allergies (we adopted a shedding dog). Haven't had to take my allergy medication since I purchased the purifier!

I have a Dyson hot / cool. I'm heavily asthmatic, and drastically reduced my inhaler use. Easily by 90%. I also like it's a heater and I can use it in the winer. And that it has a wifi transmitter; I can program it from my phone and view the analytics. Also that it doesn't look horrible and sound like a jet engine. When the other ones can do that too, I will buy. 👍 Nothing is ever unbiased. They are always trying to shock for the views. You can't compare products with different features, as if they are the same product. They probably called Dyson and said they have technical questions. Then turned the engineer into a salesman on the spot. I'd like to see the whole interview.

When you are buying Dyson you are not just buying air filter system. Hot, cool, air filter, internet app control, design, quality. All these cost money. Sometime these filter system don’t even a proper timer or remote. I would do that DIY filter box fan for my basement, not for my bedroom. I don’t think it matter much air a device can clean per hour if it can not move around to create even more air flow. You want it to get the corner as well.
