“Favorite purifier!Favorite purifier!: Without a doubt, this is our favorite air purifier. It’s the best bank for your buck, I love that it connects to Wi-Fi and I can adjust the setting from my phone. I it alerts me when to re-order the filters. It collects so much dust from the air. I’ve had other purifiers where I could tell if it was working or not, but this one I for sure can because it will kick itself and adjust based on what’s going on around us. It’s the perfect…”
“Great for better air quality! HVAC pollution, Pets, Dust.Great for better air quality! HVAC pollution, Pets, Dust.: I live in an old New Orleans shotgun home where we have huge oak trees. Between the old house, having to use Merv 8 filters for the house to pull air. These are great! So great I bought a second one for my living room after a week! I have one in my living room with my cat and my bedroom.Pros: so far Ive had much better sleep! The system measures air pollution…”
“Nice effective air cleaner.: This replaces my 10 year old air cleaner and the sound level is noticeably quieter. Love the beauty appearance. We live near the beach with a constant breeze so having the windows brings in a lot of dust, which the device does a good job for trapping. My air smells cleaner because of this device.Read moreRead less”
“Much noisier than advertised - 65 decibels - but cleans well: The product description says the noise level when running at maximum speed is 50 decibels. I used a sound meter (with no other noise in the room) and found the actual noise level is 65 decibels. That's false advertising in my opinion. I had to move more than 12 feet away before the noise level dropped to 50. The other fan speeds are much quieter and sleep mode is basically silent, but that means the fan is not…”
“Great Product, Filter Lasted Longer Than Advertised: I purchased two of these Air Purifiers in April of last year (currently February, ~10 months later) and am extremely pleased with the results and effectiveness of the product.I live in Brooklyn, NY in a railroad style apartment (one side facing street near-ish a busy road, the other side facing an interior courtyard) and I purchased two 311i Maxs. One is in the the threshold between the kitchen/living area and bedroom area…”
“5 Stars: ★★★★★ Noticeably Cleaner Air and Whisper QuietAfter using the BLUEAIR Blue Pure 311i Max Smart Air Purifier for several weeks, I can honestly say it’s one of those purchases you don’t realize you needed until you have it.The first thing I noticed was how quiet it is. On the lower settings, it’s barely noticeable, making it perfect for a bedroom or living room. Even on higher speeds, the noise is more of a gentle white noise than an annoying fan sound.The setup was…”
“Get the 311i Max Purifier - Backed by Amazing Customer Service: This air purifier changed our lives by eliminating fine dust (due to living in a windy desert). Our home stayed clean and allergies were greatly reduced. I sang it's praises and even gave one as a gift. But one month before the 12 month warranty expired, it just stopped working. I contacted customer service who replied quickly with 4 different procedures to try. Nothing worked. So they promptly sent a new unit…”
“Excellent product, does what it’s supposed to do less dust in the house and odors. Cleaner air!: This air cleaner works very well in my home. I noticed less dust, which was my biggest problem. It is quiet and I love the fact that you can use the app to adjust it whenever you need to as I have one upstairs and one downstairs. I can adjust the speed or turn it to auto or even turn it off whenever I need to without getting up by using my phone even when I’m not home. I also…”
“Highly Recommend, Best in Class, but Has Flaws: Best air purifiers I have ever had in my life- so good that I bought one and then another 3 days later and we are going on 1.5 years with 2 now. I am not a freebie or paid reviewer or whatever and I stand behind the 211 as an awesome product. I told my HVAC guy that I didn't think my airflow was right because my filters were almost new looking and he said everything was fine- you're just clean livin'. Nope. Messy as hell and I…”
“Has Performed Beautifully...: ...after 10 months of use in a 2100 square foot house. I run it on automatic and the fan speed remains low, while moving air and staying quiet. The performance of this unit is quite remarkable beyond what my HVAC cleans with a MERV 11 filter. This product is especially helpful when noticable odors are evident - as from cooking. The unit almost immediately senses the odors and begins ramping up the fan speed to clean the air. It works rather…”
“Very quiet and efficient: So far so good, I did quite a bit of research prior to making this purchase. Pros-Easy set up pretty much plug and play. Whisper quiet I rarely hear it on, which implies it does not need to use the highest fan setting to efficiently clean the air. I like the idea of a washable filter I have a Honeywell 50250-s and an AeroMax 290 that are about 6 years old. I needed ones for other rooms, so I added these which are rated higher according to Consumer…”
“Good but probably not needed: Probably didn't need this since I have UV on my furnace as well as Merv 16 filters along with a Lennox whole home Healthy Climate HEPA 60 unit attached to the furnace but since I have COPD I need the cleanest air I can get. Never reads anything higher than 2. Most of the time it is 0 detectionsRead moreRead less”
“Outstanding Air Purifier for Large Rooms — Clean Air You Can Feel!Outstanding Air Purifier for Large Rooms — Clean Air You Can Feel!: I’ve been using the BLUEAIR Air Purifier for Large Rooms for a few weeks now, and it’s been a total game-changer for my home environment. From the moment I turned it on, I noticed a real difference in air quality — the air feels fresher, cleaner, and there’s a noticeable reduction in dust and odors. Our daughter has very sensitive allergies…”
“The price will make you blue, but the results will clean away the blues.: It cost about $265 with sales tax but it cleans the air space within your home within an hour. It gives the readouts for the different grades of particles in the air, ultra fine, fine and coarse sizes. It is pretty quiet as well. It is not too heavy so pretty easy to move around but you have to grab it by the bottom. It also can operate from your smartphone using the Blueair app. The filters need…”
“Excellent Air Purifier!: Pros- Packed well. Arrived undamaged.- Started right up.- Easy WFI connection.- Easy to control via phone app. Can start it up in advance of bedtime, for example.- Easy program via the app for different on-off periods, and speeds for various times of the day or the week.- Control lights can be turned off, yet the unit can still run as directed. Good for the bedroom.- Very quiet at the lower speeds.- Display show air quality very well.- The air…”
“Great Air Purifier!: The 2111iMax works great! It removed food odors quickly and pollen from my home when someone had a window open. It is quiet on setting 2 which is what i have it on all the time. I like the light dimming feature, the lights can also be turned off, the touchscreen, sleep and auto mode.I love that it's AHAM Verifide: CADR 450 cfm Pollen, CADR 452 cfm Dust, CADR 435 cfm Tobacco Smoke at 674 sq. ft. The air purifier was packaged well and arrived without…”
