Have in our living room very quiet

I have a lot of allergies, these are great & have made a big difference in my life. I have bought two different sizes for different rooms. The auto mode is highly effective.

I used to have a blueair 211, the square one which worked fairly well for about 4yrs until it started making a high pitched whine and the fan blades were clogged with dust with no way to get in there to clean it. So I bought this one. Very lightweight but also had an annoying high pitched sound from the start especially noticable on the first speed. I quickly noticed within days this is useless at keeping dust at bay. My surfaces were thick in a few days whereas my 211 had kept it down despite running on a low speed all the time and this one at speed 2. I suspect the thicker prefilter on this may be the suspect. My nose was still stuffy all the time unlike with the 211. Whenever I needed to reboot my router this purifier would not connect with the app meaning I had to delete it and reset it up again. There's no way to just reconnect in the app itself. At the 3 month mark it refused to connect with the app, it also started having power problems. Suddenly and repeatedly the fan speed would stop for a few seconds with a flashing white light then come back on again. Thankfully Amazon were fabulous and let me return for a refund. I will be purchasing a different brand and I doubt I'll be coming back to blueair anytime soon.

Great product that does exactly what is meant to do.

I have a mixed review of this product. Let me begin with the good: It is very lightweight meaning it is easy to transport and move around the house. It is very easy to use. The app is intuitive and simple to operate as well as the physical buttons on the actual purifier. The app shows you the filter life which is good. At low speeds it has low noise that cannot be heard, but on level 3 it does make a bit of noise, but still nothing too annoying. Now the negative: Since getting it, the air in my house is apparently perfect with no impurities. I do not think that this is true. I wake up in the morning with a stuffy nose due to the high pollen count. So I know that there definitely is impurities in the air, but the machine keeps telling me that my air has 0 impurities.

This is an excellent air purifier system which has exceeded my expectations. It arrived in a very large box and was well packaged with cardboard surroundings to keep it protected. I appreciate that all packaging can be recycled (except the bag which the instructions came in). The unit itself is extremely lightweight and it is literally plug and play - no assembly required at all. I powered it on and put in Auto mode. Straight away I was surprised at how quiet it was (the auto put it on the 1st fan speed). It's so quiet I wondered if it was on! When I went through the fan speeds, then you can hear the fan and it is as loud as a normal fan when on full speed. Luckily the low, apparently, is what is needed for my room. The sensor on the unit will automatically senses which mode it should be in and to my surprise the LED light on the front of the unit told me that the air quality in my room is excellent. The user manual is extremely user friendly guiding you through the different modes, how to dim the brightness of the LED lights and how to set up the app on your phone. When you first install the app it does ask you to register and when linking it to your home wifi you have to manually enter your wifi password too. This all takes a little while but once done and it's all connected you get complete control of the air purifier on your phone and even tells you how polluted your room is too. Very useful. On the whole I think this is such a great air purifier. It's lightweight (even though this model is rather large), smart looking, easy to operate, quiet and does a fab job at purifying the air. Even though straight away it told me my room had excellent air quality, I had left it overnight and I really noticed how fresh the room was in the morning. This will prove to be excellent during hayfever season!

As a man in my mid-sixties with a breathing related health problem, I’ve come to appreciate the small things that can contribute to a comfortable nights sleep. The Blueair Blue 3450i air purifier is one such item, particularly for those of us who need to quickly and quietly remove allergens from a living space. One of the best features of this remarkable device is its user-friendly app. It’s pretty easy to navigate, (even for an old duffer like me) and allows me to tailor the settings to my families exact preferences, monitor the air quality in real time, and even set a schedule that fits in with our daily routine. The air purification part of this device operates at three distinct speeds, with the lowest setting being so quiet it’s barely noticeable, and perfect for working along in the background. While the highest setting is much noisier in comparison to the night/sleep mode, but it is also significantly quicker at extracting the 'nasties' and really cuts down the time needed to purify the air in a room. The downloadable app that comes with this machine cleverly displays the air quality, using five straightforward colours, which are mirrored on the device itself. It’s quite satisfying to see the colours change as the air in a room becomes gradually cleaner. My son suffers from pretty bad grass pollen hay-fever at this time of the year, this purifier has been nothing short of a minor miracle for relieving his coughs, splutters, runny nose, and sore, swollen eyes while he has been revising for his A levels . For anyone in search of a breath of fresh air, free from allergens and other irritants, I wholeheartedly recommend the Blueair Blue 3450i. It’s a purchase you wont to regret – I certainly haven’t.

I received the item but there is no remote control. Is this product has no remote contorl? Thanks
