I got this mostly for cooking odor because I have an open kitchen and I love to stir fry stuff, and my range is not powerful enough to get rid of most of the odor. I tried numerous other air purifiers without much success, so I only have small expectation for this since the flow rate is much higher than the others I have. Boy was I disappointed at the result, it worked marginally better than my Rabbit Air and worse than the Coway, I was ready to pack it back up and return it for an $800 unit that cannot perform better than a $300 one.However my friend came by and told me to place this purifier away from the kitchen where the odor is, and put it in my living room facing the kitchen instead, pretty much against the convention of where to place an air purifier, oh boy did it make a difference. The kitchen still smell to high heaven when I stir fry my food, but the odor got cleaned up in less than 10 minutes in both kitchen and living room; then I placed the Coway and Rabbit Air at the same location, they perform much much worse than before.So for this air purifier, the optimal placement seems to be open space instead of where the source of the odor.

I bought this after putting up with a month of smoke from the California fires leaking into my home. The reviews said it is very quiet and they are correct. Not a problem to run it all night, although it has a very bright display light that can probably be turned off - just haven't tried very hard. Great and very effective product - clears the air in my large open plan main floor quickly.

It was a bit expensive but wanted a HEPA Filter that would cover a large 40x20 foot family room. Since getting this we feel more comfortable when our family visits who are vaccinated and tested before coming to visit their Grandparents. It has kept dust down and cooking smells (fish) are no longer a problem the next day. Easy for a 70 and 80 year old grandparents to move around and the app on the phone was helpful regards to how it is working and when to replace! If we could afford it we would get one for upstairs.

With 3+ months of smoky air this past summer and into fall, in California, my husband and I researched air purifiers and purchased the 7770i air purifier for the living and kitchen area. It has three speeds and lets you know how clean your air is as well as whether or not there is particulate matter in the air. There were some days the wind was blowing ash and this air purifier measured it. Amazing! Well worth the money.

Item arrived defective, so I had to return it. Decided to buy a different brand because of below issues:1. The light strip was very finnicky, as it would not turn on at times when I would plug the device in. When it was on it would only glow blue like the air quality was excellent.2. It would incorrectly state the humidity and temperature in my room, and it would only re-calculate those two things after I unplug and plug it back in.3. I had trouble at first connecting it to the Wi-Fi app, so I see why others have frustrations with it. It would disconnect and not re-connect until I deleted it from the phone app and re-added it. It stayed connected then.4. It would not filter the air at all, no matter the settings I would change. I know it sucked air in and blew it right back out, but that was it. Smoke came into the room and it would suck it in and just blow it right back out in all directions, making the smoke problem even worse.5. This one is connected to the 4th problem I had with this air purifier. The screen numbers would always say 0 and would say the air was excellent in my room when I know it was not excellent. The numbers never went up when it sucked a bunch of smoke in and blew it right back out.6. I contacted Blueair's customer service and it sucked. They take 3 to 4 days to respond and ask me if I tried powering it off and on again, like I did not already do that among other things multiple times. I tell them I think my unit is defective and they never responded back to me. I guess their customer service department does not care.

We have two of these, and there is a noticable improvement in the air inside our house and in a family member's house. We all suffer from hay fever, and live in dusty conditions, and you can immediately tell the difference as soon as you walk inside. Would absolutely recommend.

Setup was fairly simple although the detailed setup instructions don't indicate the exterior wrapping for the air filter has to be removed (it ships already installed).There was a tab sticking out of the device indicating the wrapping needed to be removed -- but the instructions including the quick guide just say to plug it in and turn it on.The physical device interface and the interface on the app are complex as a lot of real time and historical usage data is displayed. Many weeks later I'm still somewhat confused.When opening the app and looking at the device data log there is a long pause for the data to refresh and display. Until you learn to wait for the refresh, you might not see accurate real time data.The device monitors air quality and then automatically sets the fan speed. The fan speed impacts how fast the filter is used up.Running the filter for 5 minutes on high speed fan (max speed) used 1% of the filter life. Allowing the device to Auto set the fan speed results a much longer life expectancy of the filter.The filter runs very silently and auto sets the fan speed based on real time sensor data. For example of located near a kitchen it will detect when you're cooking and run the fan art a higher speed until the air is cleaner.I use the app on an Android 6 Pro

Love the app. It shows the air quality inside and outside my home. I don't know the source of the outside air quality info since there isn't an outside sensor but it seems accurate. It's made a noticeable difference with the fire smoke this summer.
