Fresh air and very quiet. This is a great air purifier if you are looking to reduce any smells or stuffy air. I live in an apartment with carpet, and this purifier got rid of the unknown smells and stuffiness that comes with apartment living. It connects to wifi and the app allows you to schedule times for different fan speeds and other settings like night mode (turns off the display lights). It's a very well-designed product and looks like a modern device (reminds me of Tesla or BMW). It even picks up on cooking smells, which you can track in the app. If you are chopping onions or sauteing food, this purifier will help. We were cooking a crock pot meal one day, which usually permeates through the whole place, but the Blueair purifier must have been doing its job. Also great for checking humidity, temperature, and the levels of PM particulate matter in the air.

Have used this now close to a month. We use this in a living room , with an open kitchen behind us. It kicks up whenever we start up cooking , clean up VOC gases ( I guess its VOC, my knowledge in gases is poorer). We can see all the operations on the app. Its very easy to operate. Connected with alexa but didn't have to use voice commands. I set on a schedule , so it takes care of itself. Main reason I bought it is because it kills COVID germs. I even reached to Blueair customer support to confirm the same and they did. However in reality I don't know how effective is it to kill COVID germs, I don't have any devices to measure that. However with this in the room, I feel the air in the room is clean and fresh.

The Blueair HealthProtect 7470i with GermSheild has been a breath of fresh air in our home. The quality of air in our home, specifically in our bedroom, has improved significantly to the point where you can tell the difference when you walk into another room, it also does an amazing job removing odors, and airborne viruses and bacteria’s and the best part its quiet, so you don’t even know when it’s working. So, let’s go over the Pros and Cons of the Blueair Healthprotect 7470i. THIS PURIFER HAS NOT BEEN TESTED AGAINST COVID-19. Unboxing and Setup- So, the setup process on the Blueair Healthprotect is extremely simple. Simply take the air purifier out of the box, open the side panel revealing the filter. Take the plastic off the filter, place the filter back into the unit and close the panel, and you are pretty much done. The unit is ready to the clean and purify the air in your home. Blue air does have an app and I would highly recommend downloading the app to be able to connect the air purifier to wifi, remotely control the air purifier, and check on its cleaning status. The app also keeps track of the life of the filter, child lock control, and setup a schedule. -Features- This air purifier is intended for an area about 418 square feet. We have this setup in our master bedroom which is about 250 square feet and have it setup on auto mode with the Germshield mode and it takes roughly about 10 minutes to clean the air. This purifier works by pulling in air from the bottom and pushes the air up through its HEPA, Antibacterial, Antimicrobial, Activated carbon filter to clean and filter 99.97% of airborne particles, dust, dander, pollen, mold and kills 99% of bacteria and viruses caught in the filter and also to remove any odors. THIS PURIFER HAS NOT BEEN TESTED AGAINST COVID-19. The purifier also features a very sleek looking touch pad and 2 inch by 2 inch color display which shows you the current status of the cleaning process, current temperature and humidity levels and buttons to control the unit. The unit has two wheels on the bottom so its easy to move around from one room to another. The unit measures about 27in Height, 10in Width, and 12in Depth and roughly weights about 35lbs, so its fairly easy to move about the house. Pros- Works extremely well – Even removing odors, and air freshener smell. To put this unit to the test I sprayed an air fresher around the blueair to see how well the air purifier works and with in a few minutes I could no longer smell the air fresher, and neither could my wife. The purifier pulled everything in, even the air freshener, the cleaned the air. Cons- I could not find anything on the unit at this point. This unit performs really well in cleaning the air in your home, I would definitely recommend this to anyone looking for portable air purifier.

First up, on opening the Blueair HealthProtect 9470i found it is an attractive air filter which will look great in any room at home or office. The style, lines and appearance reveal its Swedish heritage/design and development. Beyond the brilliant styling, the Blueair looks to have been well engineered and constructed. The layout of the system is quite simple to manage, from filter locations, filter replacement steps and the intuitive control panel. Setup was a snap, simple and very straight forward. Had the unit running within about 30 minutes after browsing the setup instructions. QR scan the Quick Start Guide and install the Blueair app and simply follow the installation prompts – Blue Tooth connection for app. App is well-written, could be a touch more intuitive. System includes a professionally written manual, which I always appreciate. The manual is easy to follow and explains the system thoroughly. Maintenance on the system will be simply accomplished in few steps. The Blueair will notify you when to replace filters which requires only opening a side door to remove and insert the new filters. This is my third HEPA filter in my home and has replaced an older system in the master bedroom. Blends into the room with a with a quiet expression of style. A perfect match for the room. The fan has three settings, running the on low is whisper quiet at (22 db) and on high is in the range of a “normal conversation” at (45 db.) In other words, it is quiet, superb for TV viewing. “ENERGY STAR rated using less energy than an incandescent lightbulb on high (48 W).” That is a fantastic achievement for an air filter that will manage a medium size room. Excellent. LED touch control panel and info read out works great and looks genuinely nice, quite intuitive to manage the unit. All the control panel functions are accessible within the Blueair app plus the ability to set schedules, dim LED brightness, create custom location name, set child lock, and other settings. It would be nice to have a “Night” button the control panel rather than having to get my mobile to switch the mode. Would be nice to have a remote to manage the system from across the room. Control Panel shows Humidity, temperature, Air Quality info, filter indicator, controls, and air quality data – comprehensive and includes auto control which operates/adjusts the system based on air quality. Excellent read out for particulates, gases, humidity, and temp. All of which is assessable on the mobile app. Well thought out. Notes: • Supports Alexa • Wi-Fi operates at 2.4 ghz • Monitors air quality – particles, gases (tVOC) • Two Pre-filters and two main HEPA filters • HEPA filter replacement is $70 – nice price point • Cable winder underneath where you can wind excess cable – nice touch GermShield technology “functions to prevent bacterial growth” and kill germs – removes 99.97% of viruses, bacteria, dust, pollen, dander, mold, odors and 99% of germs. Do I like the Blueair HealthProtect 7470i, absolutely. Gorgeous for an air filter system, checks all the boxes for a High-end air filtration system and does so without breaking the bank.

We have a Blueair 211+ auto and it works great, the main reason we bought this 4740i is that it can provide the particle pollution data (pm10, pm2.5, and pm1.0). It is a little disappointed that most time during the day it says 0 for all three reading unless there is the strong burst of dust ( I intentionally clapping on the dusty gloves in front of the sensor to see if I can get any non-zero readings), the sensitivity of the sensor is not good, at least for the unit we have. Yes, it does do its job and filtering the particles well. The noise level is low at fan level 1 and below. We set up the fan at low levels during night time. The app is good. Considering that this model is much more expansive than the one we already have ( minus one point) and the new feature does not meet our expectation ( minus one point), we give this the three star rating
