Blueair - Blue Pure 411i Max 219 Sq. Ft HEPASilent Smart Small Room Bedroom Air Purifier - White/Gray

Having not owned any air purifiers since the sharper image ion filter purifier craze of the 90s, I was skeptical of the Blueair filter. Would it be effective? Would I even notice a difference? Blueair is a brand name I’ve seen and associated with filtration for a while now, but was it just hype? Thankfully, I’m happy to report that my worry was entirely misplaced. This is indeed a great air purifier. Starting off with appearances, this is not a small machine, but not huge either. It’s about the same footprint as a wastepaper basket, although taller at around 19 inches. It’s relatively light and most of the weight comes in the top portion of the unit – in pictures that would be the white area above the gray filter mesh. Below that head unit is mostly empty space occupied by the filters. The packaging clearly states its proud Swedish origin, and the design is what I’d call Swedish modern influenced. To me, it doesn’t stand out any more than it blends it. It calls just enough attention to itself that one could just as easily ignore it as they would be intrigued by what this object is. Functionally, the power cord feels long enough to accommodate being placed nearly anywhere. The controls are on the top of the unit, where the fan unit resides. There are two touch sensitive buttons: power and fan. The fan button cycles through 5 modes: Auto, Night Mode, and 3 different levels of fan strength. As the fan strength increases, so does the volume. At the third and highest level it is definitely loud enough to notice, but not anymore so than any other room fan would be. Night Mode is specifically designed to run at the lowest fan speed (lower than level 1) and dim all the lights fully. Speaking of lights, there’s not many. On top there’s one to indicate which mode and a small dot to indicate if you are connected to wifi. On the front of the top portion of the unit is a slender light that changes color to indicate air quality status (Blue for excellent, green for good, yellow for moderate, yellow for polluted, red for very polluted). The lights, even at their brightest, aren’t very obtrusive. The filter itself, comprising the larger part of the unit, has two parts: the replaceable filter and the pre-filter. The replaceable filter, depending on your air quality level, should need to be replaced every 6-9 months, which feels very reasonable to me. The pre-filter is the gray fabric you see surrounding it. This can be vacuumed or even washed. This can also be bought in other colors, too. The phone app is the other part of this air purifier. It was very easy to set up, using Bluetooth for the initial connection to the unit, allowing the unit to connect to your wifi. From that point on, all functions of the air purifier can be controlled remotely from the app. This includes adjusting the modes, a child lock to prevent changes from the touch buttons on the unit itself, adjusting the LED brightness, seeing your filter life status, and two very cool features: scheduling and welcome home. Scheduling lets set everything from mode to LED brightness on any recurring schedule you’d prefer. Welcome Home is a geofencing feature. This allows you to have it go into standby when leaving your home and automode when you return (unless you return between 9pm and 8am, where it goes into night mode), all without having to do anything but have your phone with you when you leave and return. As a stats nerd, my favorite features are the air quality graphs. On the main screen of the app, after putting in an address, you’ll see the air quality index for outdoors. On the screen for your purifier, of which you can add several, you see the same air quality graph for that particular unit. It’s interesting to see how the indoor air quality can be affected by the outdoor, and how the Blueair purifier works to correct this. My air quality in my work from home office that I share with my dog was good initially upon starting the unit and has remained on auto mode and excellent air quality after about the first two hours or so. My office is a smaller space, doesn’t have the greatest HVAC circulation, and when occupied for hours upon hours by both adult male and dog is not terrible smelling, but there IS a smell. With his air purifier running the stale smell of being occupied has been non-existent. On rainy days, I’ve often noticed a cat urine odor from my yard that enters my room. I’m happy to say it’s been rainy for two days and I’ve not noticed that odor at all! My experience so far with the Blueair 411i Max has been fantastic. I’m a complete convert and will be looking at more units for other areas of my home. If you, like me, were unsure of air purifiers but have considered a purchase, I’m happy to say that this is the real deal and definitely works as advertised.

I am extremely happy with this air purifier. I subscribe to Consumer Reports (highly recommend! They're a nonprofit testing company) and they rate BlueAir very high. I picked it up on Black Friday for $118.99. It is super quiet on Auto and Fan level 1. I use the app to turn up the fan to 2.5 for when I'm sleeping to get a nice white noise. The first morning I i woke up with it running I could tell something was different. It's tough to explain how the air can feel so clean. Another bonus is the name brand filters are $30, which Best Buy sells or you can get a small discount by ordering directly through BlueAir. Definitely a 5 star product.

I live near a busy road and have had several air purifiers through the years to try and keep the air circulating in my house as clean and fresh as possible. The majority of those that I’ve used in the past have been manufactured by Honeywell, and I had not previously heard of Blueair. If you’re in the same boat and the brand Blueair is unfamiliar to you, don’t be deterred because this unit is about as good as purifiers get. Given the size of the unit, and its coverage square footage wise, I opted to plant this thing right in my home office which is a smaller-sized room. It looks so much more modern and far less utilitarian than the two Honeywell purifiers I have in other rooms, and ties together nicely with the rest of my furniture. It’s slightly taller but about the same circumference as a small trashcan. The whole base of the unit comprises the replaceable filter and cover (which is machine washable), while the top of the unit houses all the touch controls. Of course, this unit has all the basic fan speed adjustments you’d find on other purifiers. But what sets this apart from others I’ve used and currently own is the phone app integration. Using the Blueair companion app, you can add the purifier to your account and control all the functionality of the unit from your phone. In addition to all the basic features you can also set custom schedules for the unit to automatically turn on or shut off, and you can set up a geofencing feature that turns the unit on or off when you arrive or leave home. Plus, it has a really cool graph to show you your air quality history (it’s a little underwhelming if your air is always pure and blue, but hey, that means it’s doing its job then!). The unit itself has an LED indicator that will change colors depending on the air quality detected, with blue being the cleanest and red indicating polluted air. I could visually see it working as it turned from yellow to red a few moments after blowing out a candle in the room, creating a small amount of smoke from the wick. A feature that’s on here that I haven’t seen on other units is the night mode which essentially turns this thing on the lowest fan setting and is virtually silent. My Honeywell does have an “auto” fan feature that will get fairly quiet, so long as no major pollutants kick that fan speed up, but for that reason, it’s not comparable to the night mode on the Blueair… especially when the Blueair also includes an “auto” fan feature. One pretty big omission to me is that there’s no simple way to set a sleep timer for the unit. I don’t like my purifier constantly running especially if I’ve left the room, so I regularly set a 2 to 4-hour sleep timer on my Honeywell units to ensure they turn off after an appropriate amount of time. While the Blueair does let you set schedules and set up geofencing for location, that doesn’t help much for day-to-day use if you aren’t on a set schedule or aren’t leaving home. Pros: -

Out of the box, I noticed that the 411i Max is much bigger than my original 411. I am glad that the aesthetics have not changed all that much. Yes, it still looks a bit like a big can, but the white finish and cloth cover make it much more pleasing to the eye. While the physical design has not changed much, the features and options have. This unit now has a control array for different settings, statuses, and options, which are easily accessible and responsive. There, you can control speeds, brightness (thank you!) and modes, of which there are several. For convenience, the purifier can be set to Auto. However, if you want a little more control, you can set it to the lowest setting in Night mode, or increase speed as needed. Some options are reached with a combination of presses, but nothing too complicated. Speaking of speeds, even at the highest setting the unit is not noisy at all with only a light humming which some may find pleasant (like a noise machine) at maximum speed. There are also some lights that show Wi-Fi connection, filter status, and air quality. The most important thing for me is the air quality. I placed the purifier in several rooms and living room and to my surprise, the quality was always “Excellent”. I am hoping that the sensor is working correctly since I placed the unit where my puppy sleeps and still came up “excellent”. I had a satisfying experience so far with my original 411 so I am confident it will continue with the 411i. Using the companion Blueair app, which I highly recommend downloading, things get a bit more interesting. After creating an account, connecting to the unit is easy enough via Bluetooth. In the app, you can control speeds, modes, brightness, set timers and schedules, see the filter’ current life status, and most importantly, the air quality in an easy-to-read graph. You can even do this while away -with voice assistant option! Maintaining the unit is straightforward. A few steps to dismantle the unit, change the filter, put back together, and reset. The fabric cover is washable (and interchangeable with other colors too). The 411i may seem somewhat pricey but having long-term experience with Blueair, and with the robust features and app support, it is totally a great value in my opinion.

It was pretty good I live in basement. That’s why I buy this air purifier worth it..

Best investment I made this year. It’s set up on my nightstand and set to automatically come on when the air is unhealthy. Works like a charm!

Made a noticeable impact to the air quality in my bedroom within the first hour after I plugged it in and set it up. Aside from doing exactly what it’s supposed to, it’s tech features are my favorite including it’s app with my home air quality dashboard and especially the ease of using my Alexa to turn it on and off and change the fan settings.

This air purifier works great, would recommend this for any home.

Obviously doesn't take the place of physically cleaning your room but I have seen less dust accumulate on my bedroom furniture. The ceiling fan blades are also less dusty. I actually prefer keeping my purifier on our dresser. Looking to buy an additional one for another bedroom. Pleased with this air purifier
