Unfortunately, it is very noisy.
I do not compare it to the Rohnson R-9600 that I already have, which is clearly in a different class! So I do not expect it to work like the R-9600, but the fact that I have 200 turbines at work at the airport and another one at home is unfortunately annoying.
Otherwise, you get what you pay for, fair if I did not have the comparison measure, it does its job in its own time with its noise.
It is of newer technology, so the wifi connection also does its job correctly as it should.
Unfortunately, I skimped on the 130+ euros more in the purchase of the Rohnson, which I will go and spend soon anyway.
I have had it for about 6 months, I can say that it does a very good job in filtering the air, the difference is noticeable in the room (12sqm) where I have it. I will tell you at the beginning to put it on full to work hard so that it cleans your space quickly and then put it on the low setting (it has in the app and depending on the square meters it can clean) so that it does not make a noticeable noise. It is worth the money but I deduct one star because it could have an ionizer. Otherwise, it's worth it, guys, if you want to do your job, put it on full for a few minutes to clean your space and then on the low setting for maintenance.
I smoke a lot. It is much more effective than another one I had (from a different company). It is user-friendly (for example, you can adjust the exact intensity you want from the application). However, it makes noise at high intensity.
Before I mention this specific cleaner, I would like to make some remarks about air cleaning methods:
An air ionizer is a device that releases negative ions into the air, which then settle on surfaces such as floors, walls, and furniture. These surfaces should be cleaned as the inhalation of ions in the indoor air can neutralize the microorganisms already present in our respiratory system, thus weakening our immune system.
The air that passes through the air cleaner with UV lamps is intended to be disinfected by the ultraviolet radiation it produces, but the microorganisms need to be exposed to the light for minutes instead of the few seconds it takes for the air to pass through a cleaner. Additionally, the ultraviolet radiation produces a load of ozone.
Air cleaners with HEPA filters remove 99.97% or more of airborne particles by drawing in air from the surrounding space, forcing it through the filter, and then releasing it fresh and clean. However, a HEPA filter cleaner does not eliminate odors. For this reason, an activated carbon filter is needed to remove gases and odors. This particular cleaner has a carbon filter.
While the World Health Organization sets a limit of 15μg/m3 for PM2.5 particles per day and 5μg/m3 as the annual average, the EU sets the annual mean at 20μg/m3.
Exposure to PM2.5 particles has multiple health effects and can lead to permanent respiratory problems such as asthma, chronic bronchitis, and heart diseases in the long term. PM2.5 particles are also believed to increase the likelihood of premature birth and infant mortality. The air quality is not good, as can be seen on interactive maps such as https://www.iqair.com/greece.
The purchasing parameters for an air cleaner are the area of the space in cubic meters where it will be installed and how many air changes will need to be made according to the clean air delivery rate (CADR) of an air cleaner in m³/h. According to the CDC of the US, in a space with low pollution, 3 air changes per hour are sufficient, while in spaces with higher activity such as commercial spaces, the air changes should not be less than 4 per hour, with the ideal amount of air changes being 6 per hour. Therefore, the CADR is a safe purchasing criterion, but let's keep in mind that this represents the maximum capabilities of a cleaner.
To find the coverage area of this particular cleaner, we divide the CADR (360 m3/h) by 2.5, which is the height (a constant for heights up to 4m) 360 / 2.5 = 144. We then divide 144 by the number of air changes per hour required by our space (2.5 for residential use, 4-6 for commercial use). So, this machine can cover approximately 57.6 square meters in a house and about 24-36 square meters in a commercial space.
I bought this particular cleaner for the bedroom because of its high CADR, especially considering its size, which reaches up to 360 m³/h, and its high degree (99.97%) of elimination of airborne particles of 0.3 μm. I also appreciate its application, which has customization and displays PM2.5 indication, and I consider it an excellent choice. I also have a BlueAir in the living room and a Levoit for the other bedroom. In the room, we sleep with two cribs on the right and left, and let me tell you, the atmosphere was quite heavy with 4 people, but it improved significantly with the purifier. I have set it to automatically open at night and close by itself in the morning. I have had it for almost a year and haven't needed to change the filter, which can be cleaned in between with electricity. There may be better options (for example: https://www.nytimes.com/wirecutter/reviews/best-air-purifier/), but the differences are small and in its case, both the application and the ease of finding replacement parts at a reasonable price matter. I hope I helped
It seems like a good purchase.. We put it in our house to clean whatever it can clean... The house is non-smoking, we close the doors to isolate the rooms so that its performance is better.. It can also be connected to an application for some extra settings.. Optional!
Very effective, works perfectly. I would prefer it to be slightly quieter when on maximum power
Purchased for use in a smoking room... I immediately noticed a difference from the very first day. The noise level is loud according to the manual, but it covers 43 square meters according to Xiaomi. In sleep mode, it is NOISELESS (with a naturally slower air purification). The application is very easy to use and overall the device's functions. I believe it is worth the money
It does what it promises. I noticed a difference in the atmosphere in a room with a fireplace. I would like it to be a little quieter when it operates at 50 - 100%. At low speeds, it is quite silent.
If you have children, don't think about it. The clean atmosphere without suspended particles and humidity will save you from allergies, asthma, etc.
I have been using it for about a month and I am very satisfied with its performance. I bought it from a Chinese store with a European warehouse, recommended by the Unboxing Specialist in his video, for 98€ and it arrived within 2 weeks! It has the gray filter, which is superior to the purple, blue, and green ones according to other reviews and HEPA certification. Note: I use it because I have a problem with city air and allergies to dust. I would not recommend it for smokers or for absorbing odors in the kitchen (oils, etc.) at least not continuously, as it is very effective in creating a nice atmosphere with a good smell, but these two examples will definitely reduce the life of the filter.
Some positives:
• The gray filter is included and it does not have NFC (so Xiaomi cannot cancel the filter whenever it deems necessary for you to buy a new one and stop the product's operation, previous models of Xiaomi air purifiers had this lock. As a test, I ran it completely without the filter and it works normally.)
• Excellent minimal design on the device, it fits perfectly in any part of the house.
• Fully practical for changing the filter and simple in operation (few buttons and discreet, exactly what is needed, you don't even need to open the manual for 90% of the functions)
• Quite readable screen with brightness adjustment and the ability to turn it off completely.
• Really low power consumption according to my measurements. (IDLE 0.1-0.6W, SLEEP 2.15-2.8W, HEALTH MAX 31-39.8W) Note: I tested the difference of lowering the screen brightness and it saves 0.8W. However, when I completely closed it, I suspected that the PM2.5 sensors were also turned off, and indeed they were! In Auto mode, the speed did not increase when I reached PM2.5: 150 to test it with an air freshener spray.
• There is an option to disable the Wi-Fi and control the purifier with the touch buttons on it.
• The most useful function provided by the application is to adjust the HEALTH or manual mode according to the square footage of your space and your needs. I have it set to 15-20 square meters where it consumes 9W and is particularly quiet.
Some negatives:
• Unacceptable that the application does not allow you to proceed without creating a mi account.
• Unacceptable that the application forces you to accept the terms they offer for the processing of data collected by the air purifier in your home without giving you the option to refuse.
• Poor pairing process. The first time it worked within 5 minutes, but the next time I had to reset it over and over again for half an hour.
• The speaker is enabled by default, which makes a particularly annoying beep every time you press any button (if you have people sleeping in the next room, this can be an issue), and the only way to disable it is through the application.
I have had it in my possession for about a week. I mainly got it to work alongside a wood stove to clean the air in case the stove smokes. So far, I haven't tried it with the stove on since the weather is still good.
I will mention the 2-3 negatives that I noticed:
· It gave me some trouble to connect it because in the Mi Home app it was set to Chinese in the region in order to connect another device that only worked in Chinese. When I changed it to Greece, it immediately found the air purifier but lost the previous device that worked in Chinese. This is an issue with Xiaomi.
· Unfortunately, when it speeds up and works at maximum, it makes a lot of noise and it's annoying. I haven't had an ionizer before, so I don't know if other brands are quieter.
Update 27/11/22
When used alongside a wood stove, it seems to clean the air well.
The loud noise when it works at full power remains the biggest drawback.
Update 28/01/23 after several months of daily use with a wood stove, it has become one of the best purchases in terms of quality, price, and performance, and the filter seems to have worn out minimally.
Also, by using Smart scenes, you can set it to work when it detects dust from a certain point and above, and it will automatically shut off when it cleans the air in the room.
It also works with Google Assistant, but it may give you some trouble and the functions are only for ON/OFF.

Small in size and floor-standing. Quiet in operation.

It doesn't handle the smells very well... Especially with the smoke, which is why I bought it.
Excellent device, I highly recommend it without reservation
