The BEST AIR PURIFIER
5 out of 5 stars
The BEST AIR PURIFIER
When I was looking for an air purifier, my Son In Law suggested the Blueaire. This is my second Blueaire. My larger 311i+ is in the primary bedroom. This smaller one is in a guest bedroom, where my grandchildren will nap, when they are over. I have 4 dogs and even though I clean every few days, there is nothing I can do about the air quality.What I love about this purifier. This model connects to their App via Bluetooth. The App will tell you the status of your air as well as when you need to change the filter out. But the lights on the unit itself will show you how your air quality is. I keep this unit in "Auto" mode, so it will sense the air quality and kick up the speed when needed. When the air is clean, this air purifier is so silent you don't even know it's on..but you can feel the air coming from the top.These "smart" air purifiers sense any unusual particles in the air, and when it does, when it's on Auto, will kick into high gear until the air is once again reading at "Excellent", on the App...then the lights go back their normal color, and the unit runs silent again. You can also put it on different speeds that will run at that speed 24/7..but keeping it on Auto, it will self adjust as to the air quality. With my other unit, in the primary bedroom...when my husband uses baby powder, after a shower...if I use a spray hair product...if I use a spray sunscreen, from the on-suite bathroom, the Blueaire fan will kick into a higher setting...the lights on the unit change, showing it working harder..then after about 10 minutes, you hear the fan getting quiter as the air gets cleaner....so smart! I also notice my nose is much clearer in the morning, after sleeping.I didn't want the unit to sit on the floor, so I got a plant stand at my local hardware dealer.

I bought this based on a Consumer Report article. It works beautifully! It’s extremely quiet and eliminates moisture, odor and dust in our home. Our allergies are not acting up for the first time since we moved into our home 24 years ago! It has Bluetooth technology, but I don’t use it. I love the fact that the filter last so long. And, it was on sale, so that was the icing on the cake! I highly recommend this air purifier!

This device moves a lot of air with very little noise. On fan speed 1, you can’t tell it’s on. Wasn’t sure if it was doing anything because it said my air was clean. That’s good, but how could I tell if it was working? Put it in automatic mode and blew some smoke at it. It actually sensed the particles and kicked up the fan speed. So, it was working! Looks stylish and doesn’t look out of place in my living room. Set up is a breeze with the exception of getting it to sync with Alexa (not a big deal for me, so haven’t tried hard). Take it out of box remove plastic and plug it in. I researched the top 10 air purifiers and selected this one. I am very pleased with the price and performance. Review is based on a week of use.

Style: Small Room - WifiVerified Purchase
I am reviewing the BlueAir 211i Max and 411i Max series in this review as I bought both - one for living room and one for bedroom. Bottom line, these are very impressive units and for the price I am impressed and pleased with each for functionality and effectiveness. I think the aesthetics of it are pleasing as well. It looks nicer than a black box wheezing in your room.

Pros for the BlueAir series. very very quiet. On auto maintenance mode - you can't hear the thing. These are smart machines. You can monitor every aspect of your air quality through the app. You can adjust the control lights from off to bright. It tracks months of air quality data for the room it is in by month, week, day. You can adjust from sleep mode, auto, and 3 fan speeds using the app remotely. It tells you how much filter life is left. It tells you the outside air quality and compares to your inside.

Example of its effectiveness; I was sautéing some Italian sausage and onions, the unit detected the particles and immediately went into high mode for about 5 minutes until all the odor was eliminated and then went back to silent. The front LED bar changes from Blue to Green, orange and red depending on the air quality while at the same time adjusting the fan speed to address the corresponding level of air quality indicated. Same thing happened when smoking some meat on the back patio. I left the door open to bring in the food, the unit detected the smoke and the front LED went red. After closing the door, it ran on high mode until the LED indicators began to regress back to blue and the fan speed decreasing accordingly until all the smoke odor was eliminated from the room.

Cons for the BlueAir product. It is a bit pricier than other options - but for all the differences - so far, I feel the Blue Air product is definitely worth the price difference, for me at least.

What I have not addressed: the longivity of the products; the life of the filter; ease of maintaining; Both of my purchases are within the first month;

Style: Small Room - Non WifiVerified Purchase
2-1-2019 Updated....I have been using the filter now for over a year and generally have been pleased with the results my only complaint is that occasionally the filters will have a very very strong chemical or manufacturing smell i’m not sure if this is because of a change in their supplier but when I order the filters again I will return them if they have the same smell. The odor dissipates within two to three days. The filter otherwise still works just as well as it did when I originally purchased it. I highly suggest getting on a subscriptionFor the filters as it lowers the cost but you be to the judge of that. Left at 4 stars pending next filter delivery.

1-8-2018 Ibought this filter based on the reviews of organizations and users alike, overall everyone was happy with varying levels of satisfaction. Here are the items that I have observed after one month of use. #1. The unit is very quiet and I was surprised upon opening it how simple the design is. It consists of the top fan assembly. The barrel filter with the activated charcoal filter inside and a simple frame that the filter is attached to with a cloth cover. Motor is connected by placing on top and turning a bit clockwise to lock the 2 together. #2 The entire unit is slightly larger than 2 gallon cubes of milk stacked one upon the other. (IE: It won't fit on a small nightstand or under a normal short bedside lamp. Also the unit should not be enclosed on a shelf as the air exhausts from the top and the intake is from the sides all around. I have mine on the floor beside the nightstand between the bed. #3. The outer cover actually acts as a pre-filter. Be prepared to do a quick hand wash of it every week (this will help your primary filter from being clogged with larger particles that can be caught in the fabric. My filter came with a blue and gray filter cover (the pre-filter) so I will trade then off every week and hand wash and hang dry the other one. #4. That being said there was some construction going on to a building next to ours and it smelled of burning and chemicals for just over a week. Afterward I looked at the filter (because I wash the outer filter every week.) and I saw honest truth to the filter being effective because the filter was extremely dirty. I tapped out the filter outside to remove some of the accumulated dust and debris. It still is working well. I expect I will have to replace it next month. But I would anticipate changing it out every three months because I do have strong allergies and my sleep has improved so much since it's use that it's a small price to pay. I will be getting a larger unit for the living area/office. Also happy to see that the replacement filters are not extremely expensive. I have seen some of the other mfr's filters that are 50+ for a filter for a unit that covers the same area and needed replaced every 3 to 6 months (which is what this says)

After a week of using it I questioned if it was doing any good. My roommate entered and commented how fresh the room smelled. So I started to think about when the last time I woke up in the middle of the night, which was a normal occurrence. Since I started using the unit I hadn't woke during that week. Also when I woke I felt much more rested. I have always had allergies and my roommates commented I would often snore loudly. Since I started using the filter constantly no snoring and have had a much more restful sleep. I have been very happy with this purchase. I will say that this unit is best for a Smaller room of up to 125 sq ft with standard 8' ceilings. aka 1000 cubic feet of space (LxWxH) which represents how much air the filter can process effectively. Beyond that it will be challenged to perform adequately. It is small enough that it could fit in a large suitcase and I would certainly take it if I were still traveling for work where I would spend a few weeks in a hotel room and then move to another location for another few weeks. A couple things to be aware of that I didn't initially understand.

This is a great product. It really works well. We bought it to clear wildfire smoke and we are really pleased about the clarity of the air in our home. The app works very well and it is easy to use. Provides air quality feedback and information, tells you about particles in the air and has several options that help optimize the effectiveness, adjust the fan speed etc. It is not loud but also has a night mode. Truly helps my breathing.

I love this air purifier! It is bigger than I thought it would be, but I was able to accommodate it. I really enjoy the app which shows a graph for day, week or month, showing when air was polluted and when it was clean. I move it from room to room, and my condo seems very fresh. I used to sneeze in the bedroom, possibly because of a large tree at the window bringing pollen into the room, but I don't sneeze any more. The app is great for remote control, and for checking performance and air quality. I hope it is able to perform this well in case of wild fire smoke. I bought it as a precaution in case there is smoky air quality this summer. I am very happy with this purchase.

We love this air purifier. It looks great, fits attractively with our decor, and works well. It can be a little noisier when working on full, but given its large size isn’t surprising. Highly recommended!

5.0 out of 5 stars Holy quiet

To start: I've very sensitive to noises. Hearing issues, tinnitus...anything that buzzes or whooshes annoys me.

But this BlueAir unit. WOW: I know it says it's quiet, but there's quiet and there's *quiet*, and this thing is *quiet*.

I actually bought two different brands simultaneously to test them out: one with some fancy bells and whistles (ion balancer) that also said it was quiet (24db), and this one that held the QuietMark seal of approval (and claimed 18db). The other one is probably what most people would call quiet - you only hear it a little bit on low, a decent amount on medium, and you don't really want it on high for very long. But the sound was tinny, vibrational, a bit aggressive at higher levels. In contrast, this one is essentially silent on low, sounds like a gentle whir on medium, and just sounds like a regular fan on a medium setting when on high. All levels are tolerable; almost pleasant. Needless to say, the other one is going back.

Does this one *work*? Obviously to some extent you just have to assume it does. But I did take some hairspray and do a spritz spritz here, and a spritz spritz there, and its autopilot mode went into overdrive. So, at least with that brute force test, it seems to work. Too early to say more than that, but I'll update this review in a few weeks to give my impressions.

But on the noise front, at least...this thing is heaven.

5.0 out of 5 stars BLUE AIR 311i Max Air Purifier - Works great

Eady to hook up to Wifi... Been using now for 3 weeks... Air feels so much cleaner no longer wake up with congested throat. Also noticed much less dust. When I made fried chicken in oil, the purifier is at other end of the house and you can see light turn red as there is a sensor and it soaks up the smell of oil pretty quickly and light turns back to blue which is normal.. Very happy that I bought this Air purifier. I will get the smaller one for the bedroom, 411i Max
