    Blueair Pure 211+ Review

    Bought this to compare to a handful of air purifiers and ended up keeping this one. I was surprised how quickly it kicked in while cooking and it's ability to filter smaller particles. Having family members that are basically allergic to everything and saying they don't have any reactions while at my house makes me feel like I made the right decision!

    Zeus (my dog) and I live in a 540 Sq ft loft apartment, and the windows don’t open. We lived here for 2 years, and even with a few plants I could tell the air quality wasn’t up to snuff. So I decided to by Blue… Right off the bat after an hour I could tell. Now, understand, on air purifiers I suggest whatever your room size is…double it for the allowed coverage size in air purifiers. Otherwise you will be replacing the filter more than you think.

    I’ve used Blu Air purification for years. It was time to replace the old with the new and I trusted what I had before. I love the new design. It’s stylish in the home without being intrusive. It keeps the room clean and smelling fresh without any noise. You just know it’s working. You can feel and smell the difference in the quality of the air

    Silent But Healthy

    My family has allergies and as such we try to keep the house open and aired out as much as possible with the exception of cold weather and high pollen count. We live in the Pacific Northwest so the cold/rain is frequent, mostly we just suffer and pop Vitamin C and allergy meds like candy. When I got the chance to test the Blue Air Blue Pure 211+ air purifier I thought it would be a wonderful experiment not just for Blue Air but for all of us here to try filtering the air. I selected the 211+ since it has a huge area it can purify, 540 square feet according to the description and since if we close all the doors off the hallway our living space is somewhere in the 450-475 square foot range. Unpacking the unit it's all in one piece with a fabric “pre-filter) to fit over and velcro snug to it. There are some brochures and an instruction manual but that’s about it! You can remove the top fan piece to access the filter in the bottom which shouldn’t need to be changed for six months, depending on the air quality it’s filtering. Setup was easy and it's a one button activation to change from low, medium, to high, then off again and it only requires a 4 inch gap from objects on any side so you can set it pretty much anywhere to start working. We started on the high setting to jump start our clean air adventure and I had to check the instructions to make sure I didn’t miss something, the highest setting is quieter than my fan on low. I gave the unit about 15 minutes to work its magic on high before taking it down to low and it was only the air coming out the top which alerted me to it being on, the unit runs silent on low! Per the manal it says the lights dim too so that if you have it in your room overnight the LED won’t disturb you (I sleep too well for a little LED to bug me even on full brightness so I can’t speak to this very well). As long as you don’t manually turn the Blue 211+ off it will cycle on and off 24/7 in short bursts of 10-15 minutes. That LED I mentioned turns yellow to indicate the air quality is not good and turns blue when it is clean, after five months it says it will turn yellow to remind you to order a new filter too and then turn red when the filter needs to be replaced. Unfortunately it's been cold and not peak allergen season so I couldn’t put this baby to the full test but I can say that we over cooked some bacon last weekend and the house was pretty smokey. This has happened before and we open the windows and door and after a while the smoke finally dissipates and goes away, maybe 30 minutes? This time while I did open the kitchen window and sliding door I also moved the Blue 211+ into the center of the living room near the kitchen and turned on high, the smoke was gone within10 minutes! I highly recommend this product for anyone with concerns about air quality (looking at you big city folk, I grew up in California with all the smog “stay inside” advisories). The unit is simple and silent, seems like it won’t need a lot of babysitting as far as filter changes go or basic upkeep beyond occasionally vacuuming the cloth skirt “pre-filter”. As investments go this would be a good one I think for people with bad allergies especially.

    Breathing easier thanks to Blue Air

    |
    Posted .

    Can you really smell cleaner air? Yes, you can and Blue Air will help you do just that. No matter how clean you think the air in your home is, Blue Air is likely going to improve the overall air quality. I’m pretty amazed that within a few hours of powering on, the air in my home actually felt and smelled cleaner. It’s really hard to describe what I mean by that last statement. Look, my home is extremely clean, tidy, and odor free. So it’s not like my home was smelly and this removed the odors. It’s just that the air I’m breathing in feels so much cleaner, more fresh and pure. Setup is very easy. From unboxing to powering on took less than five minutes. It’s almost ready to use right out of the box. I placed the outer decorative pre-filter on the unit, removed a couple of tape pieces and stickers, made sure the main filter was in place properly (it came installed), and that’s it. Within a few hours - magically purified air. This is a rather large purifier, but it somehow just seems to blend in to the environment. Unobtrusive, present but not screaming “here I am”. The build quality is solid, and with the addition of the colored exterior pre-filters it’s also aesthetically pleasing. Speaking of the exterior filter, this is easily applied and is also easy to remove for cleaning, which can be done in the washer. Also of note, the exterior filter is not required for use. I’ve found though that it does tend to catch more of the larger dust particles and I would assume (yeah I know) adds life to the primary interior filter. There is a built in air quality sensor which monitors the quality of the air within your space and can auto adjust the purifier. Multiple speeds allow users to increase the air intake speed, which decreases the time it takes to completely purify the air in whatever space you are using. This could be helpful in a case such as maybe you burn some food and your house smells like, well - burned food. Yeah, maybe I’ve done that. Just increase the air intake fan and soon the smells are gone and the air is clean. Even at top speed, this Blue Air is quiet. I’ve had ceiling fans make more noise than this. At lower speeds you’ll wonder if it’s even on. It definitely doesn’t make itself known by being loud. There is a single light indicator which will tell you when the primary filter needs to be changed. While I have not had this unit long enough to require a filter change, I have no doubts it is incredibly easy. Remove the top of the unit by pressing two tabs and you’ll see the inner primary filter. It literally folds in on itself for removal. No screws or working through multiple steps. I’m so happy with this Blue Air. This has been such a welcome addition to my home. I would highly recommend this to anyone.

    Amazing air purifier, purchased prior to party with lots of smokers trying to beat the cold. It didn’t skip a beat! With the auto function, it adjusted accordingly and by the end of the night everything was back to normal with clean, smoke-free, and odor-free air. Highly recommend!

    Cleans The Air, No Problem!

    |
    Posted .

    The Blueair Pure 211+ Auto has impressed me both in styling and performance. In its first 48 hours of use, I've seen and felt the impact it has made to the air I breathe. With the pandemic still lingering, I've had a lot of time to transform my 500 square foot garage into another inhabitable spot in our home. A man cave, if you will. Here is where I perform my work-from-home duties, watch TV and play video games. The trouble with the garage is it's not quite as insulated nor sealed as the rest of the home, so particulate matter and dust roams freely. I notice daily because my keyboard is covered in it by the time I begin my day. The 211+ Auto changed that overnight! On the first night, I ran it full blast to get the air in a nominal state before switching to auto. Within a half hour I can already smell the difference; the air was removed of garage smells and it was very pleasant to inhale the fresh air. I couldn't believe it. Waking up to see that the keyboard had much less dust on it was a happy sight to see. The next day I decided to take it up a notch for the sake of experimentation. With the garage door closed, I took my leaf blower and proceeded to cloud the garage air with many months old dust and dirt that has settled on cabinets, crevices and everything in between. It was terrible! Immediately, the 211+ Auto signaled that the air was full of pollutants with the red light. About 20 minutes later, it had changed to amber to signal an improvement in air quality and shortly after, nominal blue. It took about 30 minutes total to change from dust storm to clear. The dust haze was gone and the air was fresh again. That's fantastic. This thing has been engineered to clean your air effectively, yet move huge amounts of air. The dust that ended up settling back on the floor and other places...well...that’s on me to clean up. Using the 211+ Auto is very simple with a single button up top with 3 lights to form a circle. Each light represents low, medium and high speed settings, and all lit means automatic speed setting using the particle detector for speed metering. I plan to use it in auto as it is the best combination of clean air maintenance and quiet operation. Medium and high settings can definitely be heard, but it's not terrible, in my opinion. A small LED in front of the unit informs you of air quality status and only illuminates in amber or red in the presence of higher levels of particulate matter. Aesthetics-wise, the Blueair Pure 211+ Auto can complement any room (or garage) by changing the pre-filter to color-match its surroundings. In my garage, I have blue and gray nitro floor tiles and the gray pre filter that comes with my 211+ Auto matches it perfectly. The pre-filter is machine washable as well. Maintenance is case by case, but for most it will be every 6 months to replace the internal filter. For my garage, I’ll probably have to replace the filter 3 times a year, but for me it is totally worth the cost. The Blueair app cannot be used in conjunction with the 211+ Auto, but you can get outdoor air quality information about your specific location (PM2.5, PM10, CO and SO2). It would have been a nice touch to add this capability to this unit since they do have other units that support wifi connectivity. You can also manage your filter replacement subscriptions in the app as well, but honestly the app doesn’t add a whole lot of value if I cannot monitor/control my air purifier remotely. This is really not a deal breaker at all as it automatically adjusts itself to the air quality so I don't have to know its status and make the adjustments manually. Just turn it on to auto and make sure to keep the power running at home. As I continue to run it daily, I often seen quick moments of the light indicator switching to amber and back to blue. It's really a comforting sight to see that it was recognizing the air quality and making automatic speed adjustments to clean the air. And it looks good too.

    Large, Easy To Use, Quality Air Purifier

    |
    Posted .

    Blue Air Blue Pure 211+ is a large floor standing air purifier. Given it's size, I have no doubt that it can filter air in a 550 square foot room quickly. Fan noise at low setting is low. I didn't hear it over my tv. Even on high, I would still consider the fan noise to be reasonable. The 211+ Auto comes with a prefilter which is easy to put on, remove, and wash. Air filters in many air purifiers have to have their filters replaced after 30 days, but BlueAir indicates that the filter is good for up to 6 months. Having to replace the filter in 6 months is definitely a plus. This model has an auto fan feature which allows the air quality sensor to determine what the fan speed needs to be at any given time. You can manually set low, medium, and high fan speeds, but I will likely keep mine on auto. The prefilter and primary filter are easy to remove. I don't anticipate a problem replacing the primary filter in 6 months. Since I have allergy problems, the 211+ Auto should be a big help with allergens this spring.

    Quietly Get Clean Air

    |
    Posted .

    I was a little skeptical about air purifiers until I began to research them and discovered how bad the air quality can get inside a home. I got a uHoo air quality tester last year and noticed some higher levels of TVOC’s and NO2 than I would have liked. I got the Blue Pure 211+ and put it in our largest bedroom, which happens to house 2 litter pans. The purifier isn’t too large and with the pre filter that wraps around the unit, it looks nice and fits with any décor. I ran the purifier in auto mode, and it was very quiet. When you walk into the room it sounds like a computer is running as you can hear the faint noise of the fan. It's not bothersome or annoyingly loud, but it is louder on higher settings. We found the lower or auto setting was adequate for us and with the amount of air the unit can purify over time we leave it on auto. There is a light on the unit, but it does more than just tell you the unit is on. It also lets you know what the particulate level is. Overall, it’s a nice, well-made unit. Another consideration you will want to investigate are filters. The filters for this unit use active charcoal, which helps with odors and NO2 levels among other things so it was something we wanted but there is a cost associated with them that will need to be accounted for down the road when replacements are needed. After 4 days I noticed that even with the litter pans in the room the air smelled better. I also took before and after readings with the air quality sensor and attached them to my review. There was a slight improvement in TVOC levels and NO2 levels. Overall, we are very impressed with the purifier. It’s quiet and gave us a noticeable difference in the air quality inside the house. Not only is the difference noticeable with our noses, but the air quality sensor backs it up. Coupled with the fact the unit gets high marks from Consumer Reports, you have a great air purifier.

    Effectively brings fresh air to large rooms

    |
    Posted .

    >> Overview The Blueair Blue Pure 211+ Auto (note the “Auto”, don’t be confused to the older Blue Pure 211+ version), is an outstanding air filter, suitable for large rooms, or as it is in our case, for a couple of connected rooms (no doors). We are able to breath fresher and cleaner air every day. After cooking, vacuuming, or while having people around, it doesn’t take long for the Blue Pure 211+ Auto to do its job and provide fresh and clean air. - Pros: Provides fresh air, Auto mode very quiet and effective, particle air sensor and light indicator, easy to operate. - Cons: a little bulky, takes somewhat too much space, no timer. >> Package and Setup I was surprised to see how well protected the contents in the package were, with foam covering the whole device. Contents in the package are: the Blue Pure 211+ Auto itself, one pre-filter fabric and short manual. Nothing out of the ordinary to setup and have it running. The only nuance was installing the pre-filter fabric, to cover the lower part of the device. The pre-filter is elastic so it is just a matter to stretch it and slide it to the proper location. >> Placement We struggled a little to get the right place for the Blue Pure 211+ Auto. It is a little bulky and my wife didn’t really like that it was “that” visible at first. I prefer functionality to esthetics, but I had to agree on this one with my wife, so we had to find a place where it wouldn’t get in the way but where it could still be somewhat centrally located. Ideally its best place seems against the wall and perhaps near to a corner (I don’t think you’d want it to be in the middle of the room, though), but you’ll need to be careful not obstructing the air quality sensor that is in the back. We finally decided to place it near the entrance to the Kitchen from the main living room, next to one standing desk we setup for work during this pandemic. The air filter is still visible with some visitors thinking it is some sort of subwoofer, but it doesn’t obstruct much, and as far as we can tell, it seems to cover the whole bottom floor of the house. >> Air quality The Blue Pure 211+ Auto is said to be for a large room, but we had it setup so that it covers the whole bottom floor consisting of two living room areas connected to a central kitchen (no doors), without counting the guest bathroom (has its own fan system) and the garage, for around 600ft square coverage. We agree in the family that it is keeping the whole bottom floor of the house fresh, easily getting rid of the smells from/in the kitchen. We have found that leaving the device in Auto mode seems the most convenient and worry-free mode, when it detects air quality deteriorating, it will speed up and get cleaner air sooner, then going back to silently filtering air without much effort. It has three speeds that you can choose for faster air filtering. It doesn’t come with a timer though, so you’d have to be mindful to turn it off or lower the speed (in our case we just leave it at auto for the whole day). >> Smell We have another air filter in the upper rooms (a different brand), and that one smells like some synthetic material, but as far as we could tell the Blue Pure 211+ Auto doesn’t (I think people will have different opinions in this regard). >> Pre-filter It comes with a cloth, advertised as a pre-filter, to cover the lower half of the device. Having this is a must, otherwise the device looks awful, the white color and the “naked” bottom part is a real eye sore. The fabric feels a little cheap and when moving the device it feels like it is coming apart, but after its final placement, the device looks somewhat cool. >> Portability Given that it is corded and a little bulky, I don’t think the intention was to make this device portable. Moving the device around feels like its parts would come apart, especially the pre-filter (cloth) feels like it will come off the device. My opinion is that if you are looking for something easy to move around, get something half its size and wireless if available. However, if you are able to find a strategic place to cover large areas, then you don’t really need to move this device around anyways.

    A Breath of Fresh Air

    |
    Posted .

    This air purifier is a little spendy, but it’s an investment in your health. Since COVID started, I know that I’ve spent considerably more time indoors. I also live in an apartment complex that allows pets. There’s lots of dust and weird smells that make their way around the building. That’s where this air purifier shines. My hallway can smell like food, dog, garbage, you name it. The moment I open my door after a long day and step into my unit that smells like nothing is incredible. Blue Air has a really good reputation and their products are easy to use. For this particular unit, I took it out of the box, put the prefilter on, removed a single sticker, plugged it in, and one tap later I was in business. With five pre-filter colors, you should be able to get the purifier to match any room’s aesthetic. I like the particle sensor that gives you a good estimate of how the air in your home is doing. When running on low, this thing is nearly silent. The only thing I don’t really love about this is the filter cost - $70 every 6 months or $140 a year. That being said, given how well this purifier works, I think the upkeep cost is well worth it.

    I am glad I chose this purifier, I have had it about a month now and it has worked great! Most of us in the house have allergies of some sort and some have asthma too and I have basically stopped all allergy meds myself because I don’t have the problems I used to wake up with anymore. It quickly senses changes in air quality and ramps itself up to take care of it being settling back down too.
