Title: A Sophisticated (and QUIET) Air Filter
Review: I am reviewing the BlueAir 211i Max and 411i Max series in this review as I bought both - one for living room and one for bedroom. Bottom line, these are very impressive units and for the price I am impressed and pleased with each for functionality and effectiveness.Pros for the BlueAir series. very very quiet. On auto maintenance mode - you can't hear the thing. These are smart machines. You can monitor every aspect of your air quality through the app. You can adjust the control lights from off to bright. It tracks months of air quality data for the room it is in by month, week, day. You can adjust from sleep mode, auto, and 3 fan speeds using the app remotely. It tells you how much filter life is left. It tells you the outside air quality and compares to your inside.Example of its effectiveness; I was sautéing some Italian sausage and onions, the unit detected the particles and immediately went into high mode for about 5 minutes until all the odor was eliminated and then went back to silent. The front LED bar changes from Blue to Green, orange and red depending on the air quality while at the same time adjusting the fan speed to address the corresponding level of air quality indicated. Same thing happened when smoking some meat on the back patio. I left the door open to bring in the food, the unit detected the smoke and the front LED went red. After closing the door, it ran on high mode until the LED indicators began to regress back to blue and the fan speed decreasing accordingly until all the smoke odor was eliminated from the room.Cons for the BlueAir product. It is a bit pricier than other options - but for all the differences - so far, I feel the Blue Air product is definitely worth the price difference, for me at least.What I have not addressed: the longivity of the products; the life of the filter; ease of maintaining; Both of my purchases are within the first month;

Title: Simple, quiet, powerful
Review: Initial impressions of this purifier are very positive. I'm not setup to test the actual purification abilities beyond an anecdotal indication that it seems to clear the air well. See the reviews on Smart Air (they think it works very well but is over priced), Consumer Reports (the 211 and the Classic 605 are their two highest rated units), and elsewhere. BlueAir is very well regarded in terms of actual cleaning effectiveness.For all the other features, here are some of my key decision points and useful tips:First, I bought both a 121 and 211+ - they have similar specs, except the 121 has a 400 CADR rating rather than a 350 for the 211. I was a bit surprised to realize that they appear to have identical motor and fan units - you can swap them back and forth, and they measure identical power consumption, and sound the same. This means the 121 gets the slight boost by simply being taller and holding a larger filter. More filter area would make for more efficient filtration, and a small boost in CADR rating.This isn't really a knock, it is just worth noting if you are considering both units. I would say the 211+ is the better value in this regard, the 121 is over $120 more expensive, has $20 more expensive filters, and only slightly more filtration capacity. If you need something just barely over the 211+ in filtration, only have space for one unit, and have a large open space, then the 121 makes sense. Otherwise, if you need more than the 221 provides, and you have a space that isn't just one big open room, then buy two 211+s - it is still a better value than most of the other comparable units, and two small units will filter an uneven space better than one loud one.As for noise, these are both very quiet units (same noise, because they seem to have the same fan). The background noise in my house measured at 38dB, and I measured on an iPhone running DecibelX, A-weighted, at 1 meter from the unit, horizontally, mic pointed at the unit.- Low - 39dB, just barely over the background noise. It is not obvious that the unit is even on.- Medium - 48dB, I can tell that it is on from around the room, but only if I listen for it.- High - 55dB, OK, now it is making some noise, but it is soft in tone, not rattling or whining. Still reasonable in volume, and easy to talk over. It wouldn't kill your conversation and if you sleep with a white noise machine it might actually be similar volume (our DreamEgg at mid-high volume is about this loud).Power consumption is as indicated on the package - 30W, 43W, 62W, as measured by my meter. Quite reasonable again given the ~400CFM the fan must be blowing.Small things to appreciate:- The unit is attractive and simple. It doesn't look like a weird 90's appliance with a bunch of random protuberances or shiny stickers. It is clean and Swedish, and would integrate with a lot of decor. The changeable pre-filters come with a light blue and a midnight blue, and you can buy others. Looks fine without it as well, pure white.- The overall construction is simple and sturdy - a metal box to hold the square (but flat folding) filter, and an upper box with the controller and fan unit.- Upward blowing and pulling from all sides makes for a lot of filter area - units that just pull in the side or front are going to have a lot less filter area for the same air flow - meaning more noise.- The button on the front is capacitive - touch to change between off -> low -> med -> high -> off. It is sensitive and easy to use - I change it with my toe while holding a baby.- The unit remembers the last setting if the power is removed and restored. This means you can use it with a timer or in my case, Home Assistant automation!- The LED showing the current speed dims to 10% after a few seconds - very nice - I'm usually forced to put black tape over everything I buy to dim the bright LEDs everyone uses.The unit does not include Wifi (pointless and risky), particle counters (not going to be accurate at these price points), a display (why does it need one?), or an auto mode (read the articles on Smart Air about auto modes - they are mostly useless and sometimes much worse than just setting a moderate level and letting the unit run all the time). Basically it has everything you want - quiet fan, large filter area, easy buttons, and nothing you don't want.It isn't the cheapest unit, but it isn't the most expensive either. Compared to very cheap units you get a quieter fan and a more proven filter technology from a vetted company. Compared to more expensive units you lose some (mostly useless) control features, and some options for multi-stage filtering or chemical canisters like you might see from a (8X the price) IQair. My inlaws have a Blueair Classic 605 and this unit is smaller and quieter, for only slightly less filtration capacity, at 1/3rd the price.All in all, an easy recommendation if the filtration capacity meets your space needs.

Review: Blue Pure 211+ Air Purifier is an amazing product! There’s almost zero assembly required. You unbox, put the washable outer filter on, you plug it in, and tap front button to turn on to start. Within 15 mins of it being on in my room, immediately I noticed how light and fresh the air is. There’s no unpleasant scent at all other than the new filter smell which doesn’t bother me. After 1 1/2 weeks of using it, this new filter smell is gone and it’s just fresh air. I love it. It gets rid of cooking smells too. I love cooking fresh fish often, and man, this purifier eliminates the odour within an hour compared to 3-4 days of lingering fish smell inside of the house. No more opening windows in the middle of winter just to air out odours. Noise Level is appropriate and can be tolerated. First level of air option is very quiet and almost no noise. Second level option you can hear the fan but sounds like a subtle white noise, Third level of air option, strong fan noise but man it’s very effective! Manoeuverability is easy. I like that the button to turn on the purifier is tap sensitive. The machine could use a nook for the hands on the sides for easier to move from one place to the other. There’s a warning label on top of the machine to carry the machine from the bottom when moving or carrying. The fan on top is connected to the filter at the bottom. There’s a locking mechanism between the two chambers, but I don’t feel it’s a sturdy lock and agrees that it’s safer to carry from the bottom and not from the sides of the machine. Weight is light for younger folks but I don’t recommend grand parents to carry the machine on their own. Overall, amazing air purifier!

Review: I've tried many, many air purifiers. This one is definitely the winner. It's one of those things where it works so well, that you don't notice it. Strange, but true. We've gotten so used to having no odors around the house that soon as we leave our front door we notice a wall of smell (smoke, cooking fumes from other residents, etc). It's very quiet, super efficient, the only drawback is the slightly pricey filter, but I'm more than willing to pay $140 a year (new filter every 6 months of continuous use/$70 per filter) for *actually* clean air.

Review: Mon épouse et moi sommes des fumeurs.C’est un excellent purificateur d’air.Un des rares qui filtre jusqu’à 0.1 micron.Probablement l’un des meilleurs sur le marché pour les grandes pièces.Sa configuration qui aspire l’air tout le tour et la redirige vers le haut est selon moi la meilleure et la plus efficace.Il est très simple à utiliser et son contrôle à distance par cellulaire est simple et merveilleux.Autre avantage, il ne fait que filtrer naturellement, il ne possède aucun gadget de purification électronique douteux et dangereux pour la santé comme certains à l’ozone ou autres, exemple.Raison du 4 étoiles plutôt que 5 :Son préfiltre devient taché jaune de saleté assez rapidement et ce n’est ni chic ni jolie à regarder …Et il semble impossible de le laver pour qu’il redevienne sans taches.Et il est extrêmement long à sécher quand on le lave.Donc, à tous les 2 mois, je dois débourser 42$can+taxes pour acheter un nouveau préfiltre.Et à tous les 4 mois je dois aussi débourser un autre 60$can+taxes pour le filtre principal.Donc, cet appareil a un cout d’opération de 432$can+taxes/an.Donc, un total d’environ 500$can/an !C’est plus cher que prévus dans leurs publicités, qui disait qu’il fallait changer seulement le filtre principal au 6 à 9 mois et de simplement nettoyer le préfiltre de temps en temps.Selon leur publicité, je prévoyais un cout d’opération total maximum de 155$can/an.La réalité est de 3.2X plus. (500$can/an)Parce qu’entre autres, je prévoyais de remplacer le préfiltre seulement une fois /an et je prévoyais payer environs 14$can comme pour leurs autres modèles Blueair.Par contre pour être honnête, sans la fumée de tabac, je crois que leur publicité est correcte.Aussi, quand j’ai vu que le filtre principal était vraiment dû, l’application cellulaire me disait qu’il restait 53% de vie à mon filtre.C’était certainement faux.Donc, pas trop fiable cette fonction de pourcentage restant.En résumé :Un excellent appareil !Mais, si vous fumez, il serait peut-être bon de regarder vers d’autres modèles ou marques qui ont des coûts d’opération moins élevés.Ou qui sont conçu pour la fumée et les fumeurs.
