Your choise isnt too bad.. your problems were CO2 and formaldehyde. Dyson helps with one of them.. These people who say it’s junk want the high CADR for other purposes - they assume you also want to remove other forms of pollutants. But if your house doesnt have that problem.. then I think dyson is a very niche purchase for your use case.. it may not be a good general use case but for your case it’s good. Thats my 2c.

Sortof.  But for the cost there are probably better units.  It also depends how big your bedroom is.  It will give 5 air changes per hour (very good air quality) for 297 square feet.   Which is I think about a normal sized bedroom ?  However it only does 198CFM so its only so-so on air power.  Dysons are know for being quiet and aesthetically pleasing...but not moving a whole lot of air.  So you can probably get even better particulate coverage...from a 90 dollar Corsi Rosenthal Box/CF Box..which does around 400CFM on high.(2x the Dyson in power for a fraction of the cost.) Unless you have formaldehyde issue or something you would be spending a lot for money for just so-so CFM power.   Lots of more effective units imo.  You could even get 2 200 dollar units...get way more CFM power...and still save hundreds of dollars.   (Most units around 200 dollars will do around 180-200 CFM, the same as this 1,000 dollar unit.). It apparently has good sensors for air quality but you can get usable air quality sensors on units for 200 a fraction of the cost too.  There's a thread on this sub with people saying the motor was squeezing or making noises and that the quality was random/they had to return some etc.   Id save money + buy things better for moving air + capturing particulates.  (Unless you have formadehyde issue.). Or...you have the money to waste and want to buy one of these + another 200 dollar unit... just to get to excellent air quality. (Which is 6 ACH air changes per hour,.this will do a very good 5 ACH at 297 sq. Feet... But again for 1,000 dollars you can get 6ACH from a 90 dollar Corsi Rosnethal Box.).   The cost-value is very poor imo.  So if your bedroom is small it may give good coverage,  however if your bedroom is big it might only give adequate/OK coverage.    You can get much better symptom relief with other units with more CFM power that will clean more air, more quickly.  More CFM = likely better symptom relief...and this only gives 198 on max.  This site has the numbers: https://housefresh.com/dyson-bp06-review/

Good brands with affordable units are Winix, Levoit, Coway, Alen, and many more.  A Levoit Core 600 for instance is around 280 dollars and does 350 range CFM...almost double the Dyson for 1/4th the cost.  Winix + Coway have great units too.  (Coway used a fungicide/pesticide on the filters for antibacterial coating at very low/safe levels but some may not like that. As well some of either brand could have ionizer so you want it with a toggle on/off in case you dont like ionizer.)  Alens are great and come with a lifetime warranty, if you remain in the filter replacement program.  They look kindof modern imo and are quiet too.  Although they don't move a huge amount of air...an Alen 45i at 450 or so...will still move about as much air as Dyson...with a lifetime warranty...and half the cost.   Dysons are just really over-priced, especially if your needs are just particulate capture.   I am not an expert in VOCs or formaldehyde but it's a type of VOC.  Essentially gasses they are harmful to humans.  Like when you buy a product and it needs to off-gas and smells all plastic-y.  Those are VOCs.  (Although I don't think formaldehyde, I think those are in some plastic items, treated wood, and other stuff.).  Point is you can get one of the best purifiers for VOCs...an Austin Air...for 750, so again much cheaper than the Dyson. So white Hepa material is useless vs gasses.  Gasses need to be absorbed by black carbon strips or charcoal/carbon pellets.  As carbon strips will bind to the carbon in the air.  And charcoal pellets will absorb odors/gasses In the air.  White Hepa material traps particulates.  For allergens you just need white Hepa.  And most affordable units have a little carbon in the filter, and/or some carbon pellets.  (Which Levoit has, I believe most Winix + Coway probably too.). Although an Austin Air will have many pounds worth and be the best at that.   Idk how much the Dyson has but prob not as much as it's price would indicate.  If you had say, a high formadehyde reading in your space, then it might make sense to get that unit.  Otherwise ..you just need allergy control via particulate capture ..so you can save lots of money and get lots of good units for that.  (Which often do have a little carbon/and or pellets to help with smoke/odors m/VOCs too.). Alens are good for both as well, with their best filter.  Idk if you have smoke/odor/VOC issue as you would need to take air quality reading to see your levels.  You likely don't have any serious issue in that regard as apparently there is a low level in most normal houses.  Maybe if you had an old house or something.  You can buy air quality monitors for 50-120 bucks or so and see the TVOC levels.  Again, many units have some carbon/pellets to help with that.  So you don't need the Dyson even if you had high tvocs, as different types will be good for different types of VOC.  That unit is ofc best for formaldehyde.  If you have the money to spend, it's probably a decent unit, however you would probably want to buy another 200-300 unit to get excellent coverage anyway.  So it's kindof a waste of money really imo.  But if you have the money to spend then you can do that.  Just make sure to add another unit for more CFM.  Id instead suggest 2 200-300 dollar units, of any combo of Winix, Alen, Levoit, Coway etc.    which will get you better quality air and way more CFM.  The Dyson is quiet but Alens are pretty quiet too.  And if you get two you can run them a little lower for more quiet ..and still have the same CFM as the Dyson...for half the cost.  Maybe even quieter with 2 units on medium vs Dyson on high.   So sound is a slight edge to Dyson...but there are ways around that, and again ..it's not such a dramatic difference...that's it's worth the cost difference.  The Dyson on high is I think 51 decibels ?  Those other brands are like 64 decibels on high.  And prob like 35 decibels on medium, so even quieter on medium with same CFM or better.   Even a 30 dollar box fan and a merv 13+ filter behind it can get 150ish CFM, almost as much as the quiet/only mid power Dyson. (198CFM.)  You definitely want purifiers and they will make a huge.....difference for you.  But get something more powerful, or for more quiet, 2 medium sized units and run them on low or medium. (It's better to run on high in general but for sleep purposes it's fine maybe.  I got used to my purifier sounds and actually like them all on high when I sleep too ..helps me sleep as good background noise, I don't even notice.  So CFM ratings are all based on high.  So if you run on low you are getting like 25 or 30% of the CFM power.  But ofc the Dyson on high...isn't getting much CFM power anyway.  Any white Hepa unit that moves a lot of air will help capture particulates and help you immensely.  So you can achieve that with much lower price points.  Id get an Alen 45i and a Levoit Core 600, something like that.  But that's cause I own and like those brands a lot.  Winix + Coway have good units too.  And even a box fan and filters do a good job trapping particulates + adding CFM coverage.  Lots of units to choose from, so see what features you like.  (And id use the extra funds to get more units in other areas of your space - for excellent total coverage.) 

If you looking for filter out dust you need the one has big and powerful fan but if you need one to filter out VOC and a microscopic stuff you better of looking for multi layer filter system with HEPA , I have used Coway for dust and Dyson formaldehyde for microscopic and IQAIR multigas for road traffic pollution next to my apartment!

There is truly no "one and done" air purifier for dust, as dust is too heavy to be pulled by typical air purifiers. The Dyson formaldehyde air purifier attempts to solve this issue, but directing air at stagnat pockets within a room to encourage dusty air to make it way towards the filter intake. That'll most likely be your best bet against dust if you don't want to manually remove it, ie vacuum, brush, etc etc.

I got one of the Dyson ones that oscillates. It's amazing.

Why Dyson, they are literally the worst AP on the market

Low quality parts. They market well using fancy CGI but the reality is constant maintenance and very expensive cheap parts that fail even after 1-3months Dyson is the most talked about vacuum when it comes to failure and shoddy workmanship

My dad has one and like many customers he's never changed the filter or cleaned the pre filtration system.......it now blows meat flavoured air hahahaha

Same one I have, and I paid less than that for it new!
