i use it as a fan too lol, since the unit doesnt have gyro or tip over sensor, it still works even if it is on its side , so during summer (as it is now here), i can just point the top at my bed put it side way, the best part is you can schedule it in the app so ill have a nice comfortable night while have little to none noise. i know it is a bit of stretch, but works.

[@twentytwo138]

Why use an expensive equipment like that? Maybe it works on the side, but who knows what effect does that have on the fan blades, maybe the ball bearings will wear out faster, even if it's moved just by milimeters... A small fan costs maybe 5€, there are even USB fans for less money..

[@parohinognoel]

Thank you sharing in-depth review about this. I bought one of this today.

[@AirPurifierFirst]

Glad it was helpful! Hope you like it!

[@patrick03star]

I have one. First it was ok. The active carbon layer did absorbed the smell, but also trapped the smell and releasing some sort of leftover odor from it overtime. Personally feel its not recommended if you have it functioning 24hrs or placing it near kitchen space. It will absorb cooking odor or food smell but the smell trapped in between the layers will stay and lingers overtime. You will need to change the filter in less than 3 months. However, for bedroom clean air effect, this works fine.

[@AirPurifierFirst]

The filters will require a more frequent replacement if you use them in high polluted places such as the kitchen. The reason is that this Xiaomi doesn't have brilliant carbon filters, such are on the Winix 5500-2 or Alen FLEX air purifiers. Thanks for sharing your experience.

[@lockhandel]

Lol, air purifiers in or near kitchens is like a torture test for any air purifier. I ise Xiaomi strictly for bedrooms only. If you want to use an air purifier for TV room or near kitchen, you must get a filter without carbon filtering. You can also put the Xiaomi filter in the sun for about 6 hours, which will allow all volatile organic gases to escape the filter due to high temperature of the sun.

[@rakamaka8489]

I have a problem with the Xiaomi Home application, in the application I only have the filter tab and that's it, there is no information about how much filter is used, I only see this information on the purifier's display when it is turned on, is it normal?

[@doanvanthang4271]

Thank you for your review. How about the Xiaomi Air Purifier 4 Pro? It has many upgrades compared to 3H like larger filters, and more activated carbon. I can't wait to see it compared to Coway AP-1512HH

I haven't tested the 4 Pro, but I plan to buy the Xiaomi 4 Pro Lite in the following months, which I will then compare with the Mi 3H.

@@AirPurifierFirst Sir, w/out the intention of doubting your respinse, have you personally attempted to control the lo-med-hi fanspeed via the OLED display without the wifi On…and it didn’t work?

[@AirPurifierFirst]

@@balkodawgie936 I misunderstood you, sorry about that. The Xiaomi Mi 3H has two different ways of controlling the device: 1. The first one is through the control button, located on display, through which you can change the fan speed, enter the sleep mode, favorite mode, and auto mode. 2.Besides, there is a smart app, through which you can do all the same but with an addition, which is called manual mode. The manual mode is basically a slider through which you can change the fan speed intensity. I thought you were talking about that feature, which is only accessible through the smart app.

Can you please tell me what kind of smoke did you use in the box? Was it real cigarette smoke or vaporizer? I'm asking because i want to buy an air purifier so i can smoke in my house. I'm planning to place it on my computer desk, and turn it on everytime i smoke a cigarette. I smoke a pack daily, so around 20 cigarettes, and i would turn the device on for around 10 minutes everytime. Do you think the filter will last me at least 6 months this way, or possibly more? Will the purifier collect the smoke immediately if it's close around 50cm? Or would you suggest me another kind of purifier? Thanks!

[@ivanr21]

Can you please help me, I have this purifier and Xiaomi humidifier. When only my purifier works I get excellent quality air, bellow 30AQI but as soon as I turn the humidifier on the quality of air gets worse, over 100. And I dont keep them near eachother. Can you please advise me how to use them, should I first use the humidifier to get the desired humidity and after that turning it off and powering on the purifier? Thank you

[@twentytwo138]

Are you using tap water? Usually it's recommended to use distilled water for humidifiers. The reason is, tap water has calcium, magnesium and other stuff in it. The humidifier will spray these particles into the air and the purifier will detect it as pollution. Especially if your home has a hard tap water, then the calcium and magnesium will be in high amounts. You can check this with a cheap TDS meter, but if you have limescale deposits on your kitchen appliances and dishes, then your water is probably hard. So i suggest use distilled water. I know this because of growing cannabis, when using a humidifier with tap water it creates a white dust like powder, all from the calcium and magnesium, and most growers start panicking because they think it's mold/mildew.

[@d.m.6529]

Hi, thank you for the review! Would it be possible to use the temperature and humidity sensor on the air purifier to set an automation rule to control other devices ? For instance, if temperature is above 20, turn on the heater in the room? Or, if the humidity is below a certain level, turn on the robot vacuum ? if not, would a gateway be needed to connect to a separate Xiaomi temp and humidity sensor and then use this sensor for controlling other devices? Thank you ...

Air Purifier 4 Lite Smart [under the other name] is the same as Mi 3H .. isn't it?

[@jadenkhor]

Question; why does the purifier need to be a minimum of 20inches from the wall or other items?

[@AirPurifierFirst]

Because if you blocked the air intake, the air purifier would make insignificant changes in the air around you.

[@ekon01cz]

@@AirPurifierFirst But it has no intake in the back. I would believe, you can place it next to a wall, but keep sides free.

[@AirPurifierFirst]

There is an air quality sensor on the back, which shouldn't be blocked.

[@garypond3451]

I'm a bit concerned in that I believe it doesn't conform to any safety standards (UL, CSA, TUV for example) other than European CE which is a self declaration of conformity and from what I've been given to understand doesn't carry as much weight as an independent safety mark.

Very nice review! :) Between this air purifier or Blueair 211+ which would you personally recommend?

I like the performance of the Blueair 211+, but it is a minimalistic air purifier, without any advanced features. Xiaomi Mi 3H, on the other hand, has plenty of advanced features, and it also has very good performance. So, I would decide the Blueair if I'm looking for minimalism, and the Xioami if I want a smart air purifier.

[@nomad1517]

Neither, if you want something that is high quality, affordability and lasts a very long time, it's either between the Oransi mod Jr or the Dyson TP07. Both have sealed systems. Both have medical grade filtration and don't loose efficiency over time. Oransi has been used by NASA in their clean rooms, at least their top end models and adopted by google, IBM, Intel, etc. Both are incredibly energy efficient. Both have very stringent testing standards. Both have great costomer service. Blue air has horrible costomer service, check out Fran Blanche's KZbin channel, she's not the only one who got jipped. Both are tested in real world conditions rather than typical lab settings. Both have certifications up the wazu. If you want to crank it to the max, Aeris health and Austin air. If you have the money.

If you’ve never used an air filter these are great. kzbin.infoUgkx_dppjvjF8BYEmPSDTcgCUdRsgWYLXNHN I ended up with three after starting out with one. The noise level depends on the 1-3 settings with how hard you want the machine to work. You can also upgrade the filters and get one better for pet hair and smells which is a must have in my home.
