- Reviewed in the United States on January 28, 2021I received my Smartmi Air Purifier last Sunday and I’ve been using it ever since. Since the pandemic started, I have been wanting to get a super high quality air purifier for a couple of reasons. 1) On the off chance someone in my house or my parents’ house gets sick, I will feel much safer if we are able to keep the air clean to keep the disease from spreading (any disease, really, not just Covid). Also, I am a private voice teacher, and the only way I will feel safe opening up in person again is to have a purifier constantly running in my studio to keep germs at bay.
I owned an air purifier when I lived in Los Angeles, but it was huge and ugly (looked like an overgrown paper shredder!). The Smartmi is big, but has a much smaller footprint than I was expecting. It is also beautifully designed and lovely to look at. The controls are simple and it’s easy to set up and use, and most important to me, it’s QUIET.
My voice studio is right around the corner from my kitchen, and all of the cooking smells leech into the room, which can be very unpleasant for some students who may not want to smell garlic or fish when they’re singing. If I have this on while I’m cooking and then go into the studio, it smells like NOTHING. Once summer rolls around, I’ll bet it will take care of my students’ odors too, since there’s nothing like having a student come in right after soccer practice! Also, with a bathroom attached to my studio, I won’t have to worry about any lingering smells.
This unit is really powerful and able to work in a large room. It has a true HEPA filter, which is something that was incredibly important to me for purchase. It also has the bonus of a temperature gauge and humidity sensor, and for someone who runs a humifier constantly in the winter, it’s great to actually know what level the room is at so I can adjust accordingly.
The app is easy to install and use. You can schedule the purifier to come on at specific times, so on days that I teach I don’t have to remember to turn it on (or off – it’s so quiet you’re bound to forget it’s working). You can see the temperature and humidity. You can change the brightness of the light or turn it off entirely. Very user friendly. The only thing I haven’t figured out yet is how to change the temperature from Celsius to Fahrenheit. Not a big deal, but I would like to have the option.
The touchless feature will be very useful for most people, it’s super easy to use – for me, I have turned it off via the app because my toddler will wave his hand over it all day long and change the settings. I’m glad that there’s an option to have it on or off. It also works with OK Google and Alexa, neither of which I have, but I can only assume that could really come in handy if you’re used to using those. It’s definitely 2021 ready!
This is really top quality. I’ve only been using it for a little under a week, but I am very impressed with the features and the air quality in the rooms in which I’ve used it.

- Reviewed in the United States on December 5, 2024Wow, it really works. We've had HORRIBLE AIQ in Los Angeles today on Dec 5, it's in the news right now and we were told to stay indoors!!!! I think its 154 AIQ where I am. When I open the sliding doors to my apt the smartmi spiked and turned red! I closed the door and am purifying my place now and it's getting down to 005 PM.. When I open the door its at like 035+! Wow! I have a small space and this device is great for cleaning the air. As a test I put it on the balcony and it spiked to 150! This purifier truly works and the indicator is correct as well
- Reviewed in the United States on April 6, 2021I have had this product for about 9 months and I am really pleased with it. I did some research before buying it and it's considered one of the best air purifiers for the price range. It's definitely not meant for very large rooms or open concept areas, as it says in the description. But it works well in enclosed areas. I bought this mostly for my cat who had some lung issues that were caused by allergy, the most likely cause being dust. I keep it in the areas that he spends most of the time in and he hasn't had any more coughing fits since using this. I'm sure there are other factors but I think this has made a big difference. I would like to get multiple of these so I don't have to move this around. But it's actually very portable as it has a handle to carry it by and is quite light. It's also had some benefits for us. My boyfriend is finding that when we keep it in the bedroom at night (by the way the noise is about as loud as fan, you will adjust very quick) he doesnt feel stuffed up when he wakes up. It also cuts the pet smell really well. If we keep it in the room with the litter box you can't smell a thing. For those of you wondering about how long until you need a replacement filter.. We have 2 cats (one is long haired and both shed a lot), carpets and we never clean but are non smokers and we just had to replace the filter after 8 months.
