  Excellent investment. I purchased the Blueair 7770i 674 Sq Ft purifier. The purifier is situated between the kitchen and living room, open space design having approximately 560 Sq Ft. I found that placing the purifier on the auto mode and forget it, does it all. The purifier sensors adjust the fan speed as needed per particle count. Open a window or cook on the stove the purifier will adjust to what is in the air. Most of the time the fan speed is on low and completely quiet. Only when high particle count and the fan is on high do you hear it working, which is good for cleaning the air quickly. I found that there is lest dust accumulation on the surface areas. The purifier monitors volatile gases in the air, color coded graph and color bar, blue to red but does not adjust the fan speed as the air becomes more polluted. There must be a reason for this but unknown to me. The app. works well . You can monitor the history of the time line of particles and volatile gases.

  The Blueair air purifier offers a new level of home cleanliness that most could stand to benefit from during these trying times. Question is, does the price tag warrant the hype? So let's get the basics out of the way. Out of the box you get the main unit, instruction book, filter and power cord. I want to start by saying this is not a small unit. I uploaded a picture of the unit with my german shepard in it for size comparison. The unit is big and will stand out however its sleek and modern look makes it so that it does not become a eye sore. The Blueair air purifier comes with a free downloadable app. Through the app you can access your unit anywhere there is a internet connection. Once connected to the app you can then see several different functions, data, and different options. Through the app the first thing you will see is your air quality, i.e. excellent, good, etc. Once you dive in to the main portion of it you receive quite a bit of info, alot more then i was actually expecting to see. You will get a graph of your PM1, PM 2.5, PM10, tVOC, temp, and humidity. At first i was very overwhelmed by the amount of information it gave you however once i took some time to sit down and read everything thoroughly i realized that its pretty simplistic even though it appears not to be. So real briefly here, your PM is your "find particulate matter" reading. And basically what this means is rather or not the air purifier detected particulates and if so of what size are they. To put it simply PM 1 is your fine particulates such as bacteria and virus, where as your PM 10 is larger more coarse particulates such as dust and pet dander. Your tVOC graph is probably one of the bigger ones i focused on as that measures gasses. My master bedroom is in the basement and living in the basement can pose some health risk with the presence of radon gasses. This unit will monitor those gases and tell you your quality level while also filtering them out. But i'll get back to touch on these items. Through the app you can also set schedules for example, at 8am you can have the fans go at full speed while your away at work then set them to tone down at 5pm when you get off and then have the unit go in to sleep mode at 8pm which will turn off all the led lights and lower the fan speed so you can sleep. If you don't like using apps that is ok as the main unit will allow you full control of everything except setting up schedules. At the top of the unit there is a full LCD screen that will allow you to cycle through the different PM levels and Gas levels as well as change speeds and activate Germshield. Speaking of which this unit offers a really cool feature called Germshield. The premise behind this feature is just as it states, it will filter out the finer particles that carry bacteria and viruses allowing you to hopefully avoid the common cold. Now let me get one thing straight Blueair does not promise this and even in there pamphlet it says that it will not protect against Covid or Sars however it does filter particulates that are fine enough to get you sick. I don't know about you but with everything going on in the world right now i'll take just about every little bit of help i can get. Now directly under the LCD screen is a LED strip that will light up different colors in order to give you a quick glance of what your air quality looks like. The strip is split in to two sections in the middle allowing it to give you two different visual representations. For example the left part of the strip represents your PM levels while the right side of the strip represents your tVOC or gas levels. Let's say your PM levels are excellent and your gas levels are moderate. The left side of the strip would be lit up blue while the right side would be lit up yellow. The colors are based obliviously on air quality, Blue=excellent, Green=good, Yellow=moderate, and Red=poor. The unit comes with a main Hepa filter that is shaped like a V and two side pre-filters that are washable. The pre-filters is a very nice feature to have for all us pet owners as it will collect pet hair allowing them not to make it to the main filter which would end up shorting the filter life. Also one thing i forgot to mention was the LCD screen will also give you filter life in the form of percentage. It will also tell you room temp and humidity also. Fan speed can not be heard at its lowest setting while at its highest setting it become a little bothersome noise wise. Now i want to talk about if it does what it claims it can. This really is a hard question to answer as most particulates and gasses can not be detected by the human eye. So how are we to judge this then? Simple put i was able to judge against the smells that i normally get due to having pets and kids. Let me give you one example. One day my dog was not feeling good and he had a accident in the laundry room which is in the basement. Now normally the whole house would smell because this has happened in the past. While when i woke up in the morning i noticed my LED strip was yellow which it never is indicating that it was picking up both gas and particulates. Come to find out my dog had obviously had a accident but the really cool thing was i could not smell anything whatsoever. The air still smelled really fresh and clean. Another to add credit to this unit is that every time my wife gets ready for work she uses hairspray and every time she uses hairspray the Blueair will pick up the gas and turn yellow. This happens every time, and i mean every time! So i know this unit is working at detecting gasses and if its detecting gasses its also filtering them as well. Having this unit in the basement gives me a lot of piece of mind as i feel pretty confident that although i may not filter out all radon gas i feel confident it will greatly help. After all some filtration is better than no filtration. The air quality that comes out also just smells more crisp and clean. At first i thought maybe i was just buying in to the hype and it was all in my head but when my teenage daughter who never notices anything came in to my room and asked why it smelled fresh downstairs i knew it had to be working. If your a pet owner then there is no doubt this is a must have. For all the cat litter or dog hair smell this unit is sure to take care of that making the house smell so clean that not even your guest will know that you have pets. We have a cat, and mind you i am not a cat person just do to the fact that i hate the smell of cat litter. After the first night i immediately noticed the smell of cat litter was gone. As big as this unit is you can easily filter a 1000 sq ft room with ease allowing your house to become more welcoming to guest while hopefully improving your health. Here's my take away from this set up. Everything about this unit is worth the price tag. The app works flawlessly and the data on the screen seems to be somewhat consistent with what we got going on in our house, such as using hair products, cooking, having animals, etc. The fact that it can get particulates down to PM 1 which can carry the common cold is an even better feature to have. Once again just so we are clear im not saying that this unit will prevent you from getting sick and neither is Blueair however if there is even a slightest possibility that it can then i personally feel its worth it as me and my family are looking for anything and everything we can do to stay healthy during this pandemic. Putting that aside though this unit does a phenomenal job getting rid of pet order. The built in removable pre-filters means you won't blow so much money on replacing the main filter. So far as of writing this review i have yet to find a single flaw yet. Everything works flawlessly starting from the app all the way down to the main unit and LCD touch screen. I understand this unit is on the higher end for sure. But i will leave you with this one string of words my doctor once told me. "How much is your health worth to you?" Pros: -filters air as small as PM 1 - Built in touch screen LCD - Comes with 2 pre-filters - Can't be heard at its low setting - App that works perfect with no issues - Built in wheels to easily move the unit - Germshield Cons: - none yet

  Breathe Easy Knowing Your Air is Pure

  ---- Summary ---- Verdict: Blueair has delivered a highly advanced and beautifully designed air purifier with this 7770i model. The 674 square foot coverage, air filtration, and protection against viruses and bacteria help ensure that my home’s air is pure which gives me peace of mind and keeps my allergies in check. That and overall health are things I don’t think you can put a price on, so in my opinion, this is a great investment. Pros: - Elegant design - Quick and simple setup - Premium touch display - 674 square foot coverage - Quiet operation - Detailed particle and gas reports - Auto mode enables hands-off air purification - Night mode keeps it quiet and turns off the LED bar - Kills germs, viruses, bacteria, dust, pollen, dander, and mold - Can be controlled remotely via mobile app - Automatically tracks filter lifetime Cons: - Large size ---- Review ---- Setup: With no assembly required, getting started with the Blueair 7770i air purifier is a quick and easy couple of steps. After removing it from the well-packaged box, a protective wrapping must be removed from the unit itself and the filter within it. All that’s left to do after that is plug it into a power supply and press the On/Off button. A few additional steps are required if you choose to set up the Wi-Fi connection, which allows the air purifier to connect to the Blueair app. Since it’s optional, there’s a Wi-Fi button on top of the air purifier that can be pressed to disable the Wi-Fi function. I chose to set mine up with the Blueair app, and I’m glad I did because it provides features like indoor and outdoor air quality monitoring, filter lifetime tracking, scheduling, and the ability to adjust fan speed, or turn on “Auto” or “Night” mode. More on those features later. Overall, I appreciated the simple setup process that allowed me to get this air purifier up and running in no time. Design: The Blueair 7770i air purifier is large, but given its ability to completely filter approximately 674 square feet five times an hour, I’m understanding of its size. Plus, it’s elegant and by far the best-designed air purifier I’ve ever seen. One of the standout design aspects is the display on top which provides detailed reports of particle concentrations, volatile organic compound (VOC) levels, temperature, humidity, and filter life. Touch controls for On/Off, “Auto” mode, airflow speed, GermShield, and Wi-Fi are located below where the reports are displayed. Additionally, there’s an air quality LED indicator bar nearby that makes it easy to tell what the current air quality level is from afar. Colors vary from red for very polluted to blue for excellent. I like that everything you need to control or monitor the air purifier is easily accessible or viewable on top. Although it’s a simple design that’s generally understandable without referencing the user manual, I highly recommend reading through it to get a good understanding of what the air quality information means as well as how to care for and maintain the air purifier. Some small but appreciated design aspects are easy filter removal, wheels that enable you to roll it from one location to another (it’s quite heavy to pick up), and a cord winder to store any excess cord length. It seems like Blueair thought of everything when designing this air purifier. Features & Performance: I’m surprised by how quiet this air purifier is, even on its highest setting. I hardly notice it’s on, which is impressive considering it can completely filter a 674 square foot room about five times an hour, kill 99% of germs caught on the filter, and remove 99.97% of airborne particles like viruses and bacteria, dust, pollen, dander, and mold (based on third-party testing). I honestly believe it’s helped keep my allergies in check, which was one of my main hopes. I’ve tried this air purifier in a couple of different locations in my home, and when it’s near the kitchen, cooking is something that inevitably decreases the air quality. Often, in this scenario, the air quality indicator bar turns red to signify that the air is very polluted. One side of the bar is for particulate matter and the other for gases, so you could potentially see two different colors at once. I notice that when I’m cooking, the air purifier recognizers that the air quality is bad right away and gets to work. Within about 10 minutes, the air is already purified and those red lights on the indicator bar return to blue to indicate the air quality is back to excellent. Other colors that may show along the way are orange for slightly polluted, yellow for moderate, and green for good. The indicator lights can be turned off if you change the mode to “Night” which will also make the air purifier run as quietly as possible. This is great if it will be in the same room someone is sleeping in because the indicator bar is quite bright on its default setting. Speaking of “Night” mode, I like that it can be scheduled in the Blueair app. The same goes for “Auto” mode, or you can manually specify a certain fan speed if you’d rather not use either of those modes. Even the brightness percentage of the indicator lights can be scheduled, or just manually set in the product settings of the app. Other app features that are nice to have are outdoor and indoor air quality monitoring so that you can see the air quality outside and inside your home at a glance, and a filter lifetime status, which can is also be viewed on the air purifier itself. The Blueair 7770i air purifier is very advanced, but I’m impressed by how simple it is to use. I just have it on “Auto” mode most of the time and feel good knowing that every time I step foot in my home, I’m breathing pure air.
