Customer Ratings & Reviews

The two in one air cleaner and humidifier is huge! But it is very quiet and very efficient in cleaning air in a room. It has built-in handles on both side for easy carrying and moving. The method it uses to humidify the air is uniquely different compare to all other humidifiers, it is using a pump to pump water to a wick filter and the dry air flowing through the wick filter get humidified and carry with it the tiny water vapor. This way, only the pure water gets delivered to the room. As air cleaner, it uses three air filters to clean the air. One at the back and two on both sides. It was able to clean air in my room very quickly. It has built in sensor located at the left side to measure air particulate and a humidity sensor located on the right side to measure humidity. Since it has integrated controls on the machine, you don't have to use the Blueair mobile app to control the machine. But using mobile app has additional features and functions like personalized humidity levels, water level notification, scheduling, outside air quality, filter life, history data etc. Filling water is very easy, you can pour from the top or you can open the back cover and slide out the water tank and pour water in that way. As a humidifier, it is not so great if you set the fan mode to auto because it will incorrectly sense the humidity of the room due to low air flow. See picture attached. I have to set it to manual fan mode. In manual fan mode, it will not stop even when the humidity already reached the user set level. Also all the filters only rated for 6 months, it becomes expensive replacing the filters. I buy because of the unique humidify method.

📦 UNBOXING: Inside the box, you’ll get the 2-in-1 air purifier and some documentation. Overall, it was packaged well for shipping so you won’t have to worry about damage during transit. 💪 BUILD: Out of the box, the Blueair 2-in-1 Purify + Humidify Air Purifier feels lightweight thanks to a plastic build, which makes it easy to move across rooms and different floors of your home. Additionally, there are fabric handles on the side so that it’s easy to carry it. On the top of the humidifier is the fan exhaust, display and capacitive controls. The display can get plenty bright but can also be dimmed quite low. The controls include the on/off toggle, an LED brightness control, a sleep timer, a metrics toggle, a fan speed control, an automatic mode, and a humidifier toggle. In the front, you’ll see a window that shows the amount of water left in the water reservoir which can also be accessed via the rear back panel. When you remove the back panel, you’ll also find 3 filters (one of which is installed in the back panel) and the wick filter. 🛠️ SETUP: Setup is overall quite simple. You’ll want to remove the rear back panel and remove the protective plastic from the filters before you start. Then you’ll want to fill the water reservoir which can either be done by pouring water over the display (which was strange to me, but it’s certainly convenient), or by removing the reservoir via the rear back panel. There is a max water level line on the rear of the reservoir, but filling it up to this line does not show a “full” reservoir from the front window of the unit, so it’s likely a conservative recommendation so that you don’t overfill and cause spills when moving the unit from room to room. Afterwards, you can either start using it via the built-in controls, or set it up via the smartphone app over Wi-Fi. Note that this unit must connect using 2.4GHz Wi-Fi. Setting it up via the app was very easy thanks to the guided process. 🎛️ CONTROLS: The capacitive controls are pretty typical compared to other options on the market. There are no “increase” or “decrease” buttons for any of the functions, so you’ll have to press any given button a number of times to rotate through the option you want. Thankfully, the options are not overly plentiful, so it’s not too annoying. One thing I dislike is that while the display is backlit, the capacitive controls are not. So it’s fairly likely that you will fumble to use the controls in the dark. You can use the smartphone app under this circumstance, but it seems like a pretty strange omission. Even so, I especially like that I can quickly set a timer to have it run for a number of hours, control the fan speed, and toggle the humidifier function with ease. 💿 APP: The smartphone app exposes all the features of the Blueair 2-in-1 Purify + Humidify Air Purifier along with some additional features like a historical graph of the PM 2.5 pollution levels and Humidity levels, the ability to view the filter life and set schedules for different configurations. I especially like that I can configure schedules so that I can use the humidifier at certain parts of the day, and use just the air purifier at other times of the day. I also like the ability to use the fan as white noise during the night, so it’s nice to be able to have it on a routine schedule so that all I really need to do is fill the water reservoir for the humidifier and change out the filters from time to time. I also like that there is an indication on the display and app when the water reservoir is low, and that I get push notifications so I can be proactive about filling the reservoir. 🧐 CONCLUSION: After using it for about 2 weeks in my bedroom, I feel that it keeps my room at an appropriate level of humidity and keeps my air clean from pollutants. I especially like that I can set it on a schedule using the app so that I can mostly set it and forget other than when I need to refill the water reservoir or replace the filters. And because refilling the water reservoir can be done by pouring water over the display, it makes the system very convenient since I don’t have to do any disassembly.

My initial reaction after unboxing the unit was it was much larger than I had anticipated. But its oval shape (26 inches tall x 12 inches deep x 13.4 inches wide and weighing 20 lbs dry) isn’t cumbersome. The built-in straps on each side for carrying around certainly help but not really tabletop size, I think. Unpacking was easy enough, but each filter (2 side purifying and one “wick”) must be untaped and removed from plastic. Once that was all done, setup using android app was easy enough – creating an account, setting up Wi-Fi etc. The app is easy to navigate and walks you through setting up machine and Wi-Fi connection. Once completed the apps initial screen shows humidity level, filter and wick percentages left. If you tap that screen, it opens the entire app where you have access to settings as well has history and can set up a schedule if you want. The unit is extremely quiet, and I notice sounds, especially at night. I mostly used low setting with humidity set to 50%. I live in a very dry area and must refill the water reservoir (holding about 3 liters) several times a day, so a larger reservoir would be nice. You have 2 options to refill - pour water into the top center of machine (Over the led display or take back of unit off sliding out reservoir and “wick filter”. The 1st option runs counter to everything I was taught from my electrician father – water and electricity don’t mix – but it seems to work fine and hopefully stays sealed. The display indicates Wi-Fi, water level, humidification mode, display lock, relative humidity %, night mode, auto mode and fan speed – but is not touchscreen enabled. There is a small but easily seen indicator (AQI) light on front of machine and colors that indicate air quality - blue = excellent, green = good, yellow = moderate, orange = polluted and red = very polluted. The light also blinks if the reservoir is out of water. Manual controls for On/Standby, Brightness, Night Mode, Information toggle, Manual fan speed, Auto Mode and Humidification on/off are top/front of unit. These function well but are not backlite so can’t see when dark. I mention this as I got up early one morning and noticed the flashing light indicating no water and had trouble finding button to turn off with no light. As far as air cleaning is concerned it seems to be working well. The maximum room size is 360 sq ft. Humidity seems much better. The unit has an auto-dry feature which I think helps dry out the wick as to stop any mold etc. from growing. It runs when the unit is out of water or fan speed is set to 0. You can override this in app. The manual states the expected life span of the purifying filters is 6 – 9 months and wick 6 months. 3-year warranty which is nice I am disappointed that the power cord is not detachable from unit and has power brick at plugin. This could make it a tad difficult to “run” cord under/through furniture. Also, power bricks have been known to go out – which would require replacing entire machine. Overall, a nice and quiet unit that seems to really make a difference on humidity in the room. I definitely recommend.

I had the need to have more control over the humidity in my house. It became a bigger priority since we welcomed a little one. I did a lot of research trying to find a purifier that would also humidify. Then this Blueair became available and it appeared to have what I was looking for. I have other Blueair purifiers, so it was good to know that I can use the same app to use this. The first thing that I noticed was the size. It’s a big product but it is not an eyesore for me. I wouldn’t want to put it in a small room but it worked at the location I wanted. Getting this Blueair purifier plus humidifier installed setup was as easy as taking it out of the box and removing the plastic wrapping from the filters. Add in the water, plug in the Blueair and connect using the app. After pairing with the Blueair you can use the app to control different settings to get the most comfortable experience. There is also the option of using the onboard controls. When it’s time to fill up with water, I can fill it up by pouring the water over the lcd screen. So far I went 3 days using the humidification on before I needed to refill. The tank takes a gallon of water. I chose to use distilled water to prevent mold and help with the longevity of the unit. This is also very quiet when running. If you need to use high speed it may get a little bit louder but not annoying. I think the filters are reusable after cleaning them. That would save me some money and I will read up on it to verify. I’m liking this combo purifier plus humidifier and I have no issues. I’m feeling a difference in the humidity and I can visualize the reading on the Blueair. I would definitely like to see a smaller version of this Blueair combo. The unit is quiet and easy to use. I like this refill process and being able to control the settings using my phone. Although it’s good to have the filters, I think it’s too many to keep up with and to deal with the cost.

The Blueair 2-in-1 Purifier and Humidifier has been a game changer for our home. Everyone in my family suffers from allergies, and we tend to get really sick when the weather changes. However, I've noticed significant improvements in our seasonal allergies recently. This combination of a humidifier and purifier has greatly relieved those unpleasant symptoms. With the humidifier on, I feel less stuffy, and my eyes don't water as much. The air quality feels amazing. Additionally, my home was previously owned by a smoker, and I would occasionally notice the lingering smell of smoke. Since I started using the purifier, I haven’t detected that smell at all. The setup was super easy, and downloading the app is a must. From the app, you can manage the settings and keep track of the humidity levels inside your home. It also lets you know when it's time to replace the filters. Refilling the humidifier is simple; you can easily add water from the top without needing to take it apart, although you can do so if you prefer. The invisible mist technology is another great feature. Personally, I like to see the mist, as it helps me relax. Overall, this is a great machine that serves two functions and covers about 1,700 square feet according to the manual, which is perfect since my home is about 1,000 square feet.This is a machine that is worthy of investment.

This winter reminded me how I needed to get a humidifier for the bedroom to combat the dryness and discomfort the cold weather causes. We recently moved and the new bedroom has higher ceilings that make the current air purifier much less efficient at lower speeds, so that needed to be replaced as well. We’ve been mainly using Blueair purifiers without any issues the last few years, so when I found out that there was a 2-in-1 Purifier and Humidifier, I had to pick it up. Pros: - Smart features that make it easier to use. - Built for humidifying. - High Air Flow. Cons: - Large size. - Multiple Filters are an added expense. - May need to refill the humidifier multiple times per day. Setup: The BlueAir 2-in-1 Purify + Humidify Air Purifier is a BIG air purifier. Standing at 26in with an oval base of about 11in by 12.5in, about the size of a tall laundry basket. It will take up a good size spot in the room and need open space around it to allow for good air circulation. This worked great for us as the new bedroom was much bigger than our old and only filled with what we’ve previously had so it’s still feeling a bit empty. This has 4 filters that will need to be replaced every 6-9 months, this is an additional ongoing cost to keep in mind. With 3 HEPA filters for intake on the sides and a central anti-microbial filter (blue cylinder) to help keep the circulated air clean. Each filter will need to have the plastic cover removed before turning on. Once that is done, reassemble and fill with water. Then turn it on! Software: The Blueair App is easy and straightforward as apps go. Setting up a new device using the guided walk through is simple. Once setup the app will tell you the remaining life of your filters in a “%” which makes it easy to order replacements in time. For the Humidifier, the app lets you know when the water tank needs to be filled, which can be daily or more depending on your target humidity setting. My favorite smart feature in the app is the ability to set “My Schedules” which are basically pre-set settings based on times of day. Using one for when we sleep, the purifier will automatically set the speed to 1, turn the display light off, and enable the humidifier. This helped simplify using the device down to a nightly routine of just filling the humidifier before going to bed and a weekly cleaning of the accumulated dust. And in the morning, after the schedule, the settings return to pre-schedule settings or a custom setting if you want. Humidifier: Being able to fill the humidifier from the top is a huge time saver, but I still feel weird about it as often water splashes out onto the fan. I often still fill it by simply taking the back panel off, tank out, and over to the bathroom sink. Being built for using tap water really simplifies the refill process, most humidifiers I’ve used in the past required distilled water only which was an added trip to the store and cost. Initially, I left the target humidity at the initial setting of 50%, but I found this left the room a little too chilled. I lowered the target humidity down to 40% and that fixed the chilled feeling. Additionally, I adjusted the settings to not run the humidifier during the day, only during the night schedule. This helped reduce the number of times I needed to refill the humidifier, from 2 times per day down to just before bed. This worked better for us, as we are not in the bedroom during the daytime so there was little benefit to humidifying the room all day verse just at night. Room Feeling: After an hour of the Purify + Humidify running on auto fan speed, with a room target humidity of 50%, which was the default, I noticed the air was crisper and cooler. I could noticeably feel that breathing was a bit easier. As mentioned earlier, I ended up lowering the target humidity down to 40% and set it for only at night to reduce the number of times to refill the humidifier. Even on the lowest speed, the room feels noticeably cleaner. On the highest fan speed, the fan noise is quite noticeable specially if it is at night when you’re trying to sleep. I tried to use the auto-fan speed at night but found it would speed up enough in the middle of the night to wake me up, I’m a light sleeper so any new noise at night wakes me up. Using the “My Schedules” to set the speed to 1 fixed that during the sleeping hours and switches the fan speed back to Auto during daytime. Conclusion: Blueair is always a great choice for air purifiers, they are usually simple and easy to maintain. The 2-in-1 Purify + Humidify is no exception, adding a humidifier to the simple design is a huge plus. There’s not too much to this one except to breath easier. This is a much-needed addition to our new bedroom.

I’m no stranger to Blueair. The 211i Max has been purifying my home for about a year and a half. It wasn’t totally sold on its efficacy for some time after first power on. It seemed more of a home accessory rather than an air purifier, aesthetically blending into the room, but rarely louder than a whisper. Was it working? Then the 2023 Canadian forest fires blew heavy smoke down the U.S. east coast and my 211i Max’s fan went into overdrive. From that point forward I was a believer. But the proof was gray color it turned the filter – and that’s over and above what my HVAC filter collected. Wow. So, when I recently had the opportunity to try out Blueair’s 2-in-1 Purify + Humidify I was “yes, please and thank you.” Perhaps I was too excited, but also uninitiated about humidifiers (any brand), because I’ve learned they require more attention than a plain old purifier. I doubt I’m alone here, so I write this with newbies, like me, in mind so you have an idea of what to expect when you open the box. But if you are just looking for a “bottom line,” this model, in my home, runs silent beautifully. It has raised the humidity in my main floor this winter from about 27% to the 35% I set as my preferred level and done so, like my 211i purifier, without me ever realizing it’s on. If there one thing I don’t love about the 2-in-1 Purify + Humidify it’s that it’s all plastic putty color and lacks the “living room” aesthetic of Blueair’s purifiers. SETUP EXPERIENCE On opening the box, I expected to find the 2-in-1 Purify + Humidify and a separate package of filters. Instead, all the filters were pre-installed. Awesome I thought – plug and play. Nope. You need to remove the filters to remove the protective wrap on them. A bit of a let down, but I’m glad I skimmed the manual or I wouldn’t have known. Oddly there is no mention of water in the manual’s setup section. Instead, instructions on how to add water are many pages back in the maintenance section. Weird for a product whose chief feature is humidification. Coming into this product clueless, I found adding the initial water awkward. The instructions outline two ways to fill the water tank – pour water into the top, where it will flow into the tank, or pour directly into the tank. Either way, the user is cautioned to not fill above the “max” line on the tank. That’s fine, except if you opt for the easy way, pouring water into the top you’d have to be a member of Cirque Du Soleil see the “max” line when filling. There is water level icon on the control panel either. So, not wanting a pool of water on my hardwood floor, I opted to fill directly in the tank. This is a clumsy, supremely annoying, but accurate process. but if you follow what I did, you don’t need to do this. When filling the tank I noted how many cups I was pouring into it since I didn’t see anything in the manual clearly noting this amount. (It’s about 7 cups). Next, I filled an inside water can with 7 cups of water and marked it. That point forward I just fill to this level and pour into the top. I wonder why Blueair doesn’t pack in pre-marked watering can to enhance the user experience. Starting off frustrated on a high-end product is not the way to introduce customers to your brand. Now you’re ready to go. Connect the 2-in-1 Purify + Humidify to the Blueair app (more on this later) and start purifying and humidifying. The app lets you set a target humidity level. I chose 35%. At the time the 2-in-1 Purify + Humidify reported the room was at 25% and my thermostat, one floor up, confirmed, reporting 23%. This is the point the 2-in-1 Purify + Humidify fan goes “all in” to reach its target. It settles down once accomplished. In my instance, it took hours long until the humidity touched mid 30% so maybe do this before leaving home for a while. My HVAC thermostat (one level up) indicated humidity increased 5% too. So, while the 2-in-1 Purify + Humidify can cover a lot of area, it’s more effective with horizontal space than vertical. But the lesson here is don’t freak out when the fans are a Mach 6 for hours after you first turn the unit on. In my experience this is one time only to get humidity to your preferred level. Once it reaches this level it maintains it whisper quiet. The other set up pain is that in raising humidity 5%+ it, obviously uses a lot of water. In the first 24 hours I had to fill the tank twice – once at first set up and then again about 12 hour later. Fortunately, the 2nd time I just had to pour water into the top. Just as the fan tamps down once it reaches its target so does water use. To summarize, setup is a pain but it’s not the daily norm of this product. THOUGHTS AFTER A COUPLE WEEKS USE The purifier part of this unit seems to be as effective as my 211i MAX. That unit sat where the 2-in-1 Purify + Humidify now sits. (I moved the 211i MAX to the master bedroom). The air smells as clean with the 2-in-1 Purify + Humidify doing the purifying as it was when the 211i MAX had that job. As noted, the 2-in-1 Purify + Humidify, after it reached my target humidity, calmed down. I typically get a “water refill” notification every 4 to 5 days. I do not delay refilling because I don’t want the humidity level to drop too much, just to avoid it going full bore again. Water refilling can be a pain because the instructions advise turning the unit off to avoid the fans pushing water back out. But I’ve found refilling when the fan is at 0 or 1 works fine. But to be sure, Blueair doesn’t advise it. This is my first humidifier I’m not yet convinced I need one. No one in the house has dry skin or respiratory issues. We do have some antique wood furniture, but it’s never shown to be drying out. But, just like when I installed the 211i, I feel I still need more time and weather seasons to give a final verdict on my own need for it. But worst case, I end up using it as a purifier only, in excellent Blueair fashion. The humidifier can be turned off, by the way, if you later decide you don’t want it on or need it on. It’s not a “all functions on” or “all off” product. What I did immediately notice was how much cooler my main floor (where the 2-in-1 Purify + Humidify lives) now feels. Maybe this will be amazing in the summer, but it’s winter now so I’m not thrilled with my main floor being touch chillier now. For clarification, the actual temperature is the same. The cooling sensation is perceived because of the extra water vapor being dispersed. ON SCREEN AND APP FUNCTIONALITY The 2-in-1 Purify + Humidify offers two ways to view current room conditions and, to some extent, change settings. The top of the unit has a large LED screen with an array of touch control buttons. Mode (Auto, Night, Manual), fan speed, air quality, relative humidity, as well as view maintenance needs can be set here. The app (iOS and Android) offers more granular options for humidity target and enabling schedules. Schedules are particularly useful if you set up your unit in a bedroom. It allows you to instruct the unit to go into “night mode” at a prescribed time nightly and then switch back to “auto” mode during the day. The app also offers performance information, including a rolling graph of the humidity level. Generally, if you want to change a setting the app is the easiest place to do it. The app is also a quick way to order or subscribe to filter replacements. MAINTENANCE REQUIREMENTS The three filters in the 2-in-1 Purify + Humidify, like most HVAC systems, must be replaced when dirty. Blueair suggests every nine months but my experience with the 211i MAX is to eyeball before replacing. I inspect the filter on the 211i when the app nags to change the filter. If I’ve found the filter isn’t that dirty, even in the deep crevices, I reset the filter timer and check back in in a few months. In the 18 months I’ve owned that unit I’ve only felt compelled to change the filter once. Of course, that’s the 211i MAX and my home, so your experience might differ with the 2-in-1 Purify + Humidify in your home. It also contrary to Blueair’s advice. But I’m comfortable delaying and saving money. The humidifier has a wicking filter, and the water tank has one too. I imagine these will need to be changed on time since they are consistently wet or moist. Given all of this, be sure to calculate this annual-ish maintenance cost into your buying decision. These filters are not inexpensive.

Was looking for a two way unit that does both humidify and purify so as to reduce the clutter in my house. Works great. The app will give you notifications as to when the water is low. The only minor issue is that you can only do one at a time, not both.

For those looking for a single appliance to tackle both air purification and humidification, the Blueair 2-in-1 Purify + Humidify is a great option. This unit effectively combines the utility of two essential devices into one user-friendly and high-performing package. Living in the upper midwest, I live in a house that requires consistent added humidification at least half of the year during winter months where relative humidity indoors can fall to 20% or less at times. Also as a hobbyist guitar player, adding humidity to my environment to get it closer to the 40-50% RH zone is critical to the long term health of my instruments. In this context, the Purify + Humidify has been a highly effective and impactful unit. Using the app (which I'll touch on more in a minute), I was able to configure the Blueair to hold my lower level at a consistent 45% humidity. This has completely taken the guess work out of humidifying the space. While this setup requires that I refill unit on a daily basis (if not more at times), this is made painlessly simple via the unit's refilling system. In a bit of an unusual feeling process, you're able to pour water directly onto the unit's top screen, which then drips down into the water reservoir at the bottom. This felt like it was a bad idea at first, but over time, I've grown to appreciate just how easy this makes it to keep the water tank topped off. In summation, for the humidify side of this product, it's hugely effective and does the job every bit as well as one would expect. On the purify side of the equation, I've found it to be equally effective. Its ability to get rid of odors of my lower level (where my office is), which can verge on musty at times, has been nothing short of impressive, giving me a sense of highly increased air quality where I spend a lot of my time every day. The Purify + Humidify's air quality improvements have been confirmed via an external air quality monitor showing a marked reduction in particulate matter. All that is to say, thankfully, the Purify side of the product seems every bit as effective as the Humidify side. For me, a huge positive component of this unit is accompanying app. While it aids with the usual setup processes to get you up and running, it also adds a host of other features that makes using this unit a nice experience. The usual things are here, like stats on your room's basic air quality and humidity levels making it easy to remotely monitor things, along with filter life indicators to make sure you stay on top of changing those out. What's been the best feature for me, however, is the scheduling function. The app gives you the ability to set up a daily schedule for turning on the purify and humidify functions separately. In my case, I've set the unit to turn on early in the morning, meaning I'm able to start my day with freshness in the air. This is a phenomenal feature and really ups the overall game of this unit. While using the Purify + Humidify has been an overwhelmingly positive experience, there are a couple minor areas that could be improved. The air quality monitoring could be improved with the unit and the app; it currently seems to only display PM2.5 data, which feels a bit behind the curve compared to other connected purifiers. And as expected, filter costs over time will start to add up, as they always do with these types of units, but especially so here given the multiple HEPA filters in addition to the water filter. If you're looking for a device that will give you both humidification and purification in one, this is the unit to look at. It excels in performance, user experience, and smart features, making it a breeze to use and a joy to have around. This feels like a great investment for cleaner, more comfortable air at home.

This probably should be how purifiers should be made-- one with a humidifier. At least in Southern California where it is so dry, plain purifiers don't do much. In my household, we don't get too much dirty air, except for cooking pollution, yearly forest fires, and occasional fireworks. So purifiers are good but not maximized. With a humidifier though, it changes the ball game, especially for our toddler who has active eczema. I've trusted Blueair for a couple of years-- it gives me insight, through the app, of AQIs and really helps me know the kids are breathing good air (it doesn't help that my dad had COPD -- so I value clean air differently). I like the idea that I can place water in its tank and forget about it for days. I like how it tells me the humidity levels and keeps the baby's room informed if we need to fire up the humidity especially that my central hvac system dries up our house air (and we all end up with horrible throats in sinuses in the morning). This device helps keep our air humid in the most subtle way-- you know, just quietly sitting in one corner. It is easy to set up, and keep running. And it's great that it integrates with Google Home. So turning it on, adjusting fan speed or humidification is only a voice command away. There are some quirks, like managing the water levels which are hard to see in the front window or kind of glitchy in the app. I have not had the chance to clean it because it is relatively new, but looking at the instructions, and how the pieces can easily be removed and put back together, looks like it is a breeze to maintain. This is the right way to purify the air-- with matching humidifier. As usual, Blueair looks good, it is easy to operate and works well without needing much attention. If your'e getting a purifier, might as well get a humidifying one.

Hello friends and welcome to my review of the new Bluair 2 in 1 purify and humidify air purifier. That's a long name so I will call it the bluair from here on. First off it arrived promptly from BB, and upon opening I was happy to see that I did not need to do much to get it going. Removing packing materials helps you get used to the operation of this unit. I could tell right away that the Bluair was a powerful air filter. There are three filters located on the sides and the door. I like this feature, I think it's filters will last longer this way. And it adds a large surface area to clean the air. The Bluair claims to filter 301 sq ft of room space, and I believe with three filters it should easily do that. Next we have to talk about the humidifier, It is unusual. The unit itself is inside the outer case and is a beautiful design. Too bad we can't look at this part all the time. There are two ways to fill the humidifier tank, first is to remove the inner unit and fill with water. The second way is far more fun, You just pour the water into the top of the unit where the display is. This seems wrong, because normally you don't want water on a display. Also if you pour water thru the top, it makes a crazy noise as the water filters down thru the machine. This is normal just sounds funny, and I like it. Finally we come to the app that can control the Bluair. The app is straight forward and easy to use. It adds a lot features at your fingertips, such as ability to control the brightness of the display screen, humidity levels, etc.. I like the app for this unit a lot, it's more convenient than walking over to it. Also with the controls and features this unit provides, I have no problems sleeping with it running. I can dim the lights and lower the fan speed and not be disturbed while snoozing. Over-all I find this unit to be a great air purifier and it helps a lot with my dry air issues. I would recommend to my friends and family!
