LevoitAir Purifiers for Large Home Bedroom 83m², CADR 400m³/h, Alexa Enabled, Filter with PM2.5 Intelligent Air Quality Sensor, Auto Mode,, Removes Pollen Allergy Dust Smoke Pet

This LEVOIT air purifier has been a fantastic addition to our home. We’ve been using it for a few months now, and the difference in air quality is noticeable, especially for me being allergic and very sensitive to dust in the air.Here’s what we love about it:Very Quiet Operation:Even on higher settings, it runs quietly. On sleep mode, it’s almost silent, so we can keep it on all night in the bedroom without it being distracting.Night Mode:The display dims and the fan slows down, making it perfect for nighttime use. It doesn’t disturb sleep at all.Smart Features and App Control:Controlling it through the app is super convenient. You can switch modes, check air quality, and set schedules from anywhere. It also works well with Alexa for voice commands.Auto Mode with PM2.5 Sensor:The auto mode is very responsive. Whenever we cook and the air in the kitchen gets heavy, we get an alert on the phone letting us know there’s been a drop in air quality. The purifier kicks into a higher fan speed automatically and clears the air quickly. It's really reassuring to know it’s monitoring things constantly.Strong Performance for Larger Rooms:We use it in an open-plan living area, and it handles the space with no problem. The airflow is powerful and consistent, and you can really feel the difference, especially during allergy season.Overall:This is a top-notch air purifier. Quiet, intelligent, and very effective. The smart notifications and automatic adjustments make it feel like it’s doing the thinking for you. Highly recommended for anyone looking to improve indoor air quality with minimal effort, and I will definitely buy a second one for my second floor soon.

This is a great filter, it definitely clears the air of dust, pet dander, etc. Noise level is ok too. I've had it for a week now, the lowest setting has developed an annoying low whine, like a squeak. The sensor like another review has mentioned could not sense dust in your grans loft. The dog shakes next to it and you see the dander explosion in slo-mo but the filter doesn't budge. It seems to only work with smoke or water/oil based particles. Ironing in the same room seems to kick it off. I also dont understand why this sensor is on the back of the machine :s Despite all this, it is a good filter, it has a great app and schedule feature which I have used to program the filter to run at various times on short full blasts during the day. I have tried to update the software, but so far the process has failed multiple times. Would I recommend it? Yes for less dust, fairly low noise, good design. Just don't expect miracles from the auto sense feature...

I've been using a manual air filter for 10 years because I live on a main road next to traffic lights on a 4 way junction. I know polution is high by the amount of fine black dust that deposits itself on my window frames. I wanted to upgrade my filter to one with a sensor and and automatic function. After a lot of research this model came closest to my needs. It is also supposed to have the cheapest annual electricity cost according to a couple of YouTube reviews. The app was easy to setup and link to the filter, and it is very useful. It has confirmed my belief that road polution increases significantly at certain times, during school rush hour etc. Monitoring over several days shows spikes around the same times but lower spikes on the weekend. I have it running on automatic mode all the time and it seems effective at reducing pollution levels fairly quickly and without any intrusive noise.

The media could not be loaded. I got the Levoit Core 400S because my cats shed like crazy, and let me tell you, it’s been a lifesaver. Before, I was constantly sneezing and dealing with cat hair everywhere, but this purifier handles it well. The app makes it super easy to control, and I love that I can just ask google to adjust it. Best part? It is a quiet unit, even my cats don’t notice it. If you’ve got pets, this thing is a must.

It’s great sits quietly most of the time and when it sensors poorer air increases fan speed to quickly return to clean air. Love the display which shows how bad air is at a glance and the accompanying app. Not the cheapest but I think it was a good buy.

This is a great product. I set the start and stop times. It’s hid behind a chair as it’s a bit bigger than I expected. I believe it has helped change the quality of the air in our front room as my husband has asthma. It is very noisy when it first starts up but then goes very quiet once it’s happy with the air quality. If it’s not happy, the light changes to red and it comes back on. It’s a great product and I wouldn’t be without it now.

Works brilliantly, does exactly what it says it would. Purchased this because my partners allergies leave her constantly sneezing and there's been a drastic reduction in this since we got this unit in the living room and a smaller in the bedroom.I think I went too big though, could have bought the smaller unit for the living room, unit is so good we never leave it on full auto and instead leave it on quiet mode or sleep.Set up is easy and the app is great (connects easily to the wifi), never need to actually touch the unit after set up.It does create a draught, which when you think about it is quite obvious, might bother some people but I think it's good for the air to be circulating and it does make the Christmas decorations on the ceiling gently move and reflect light nicely (probably not what it was designed for).Going to get another unit for the kids bedroom, will get a more suitably sized one, as quality of air now is markedly different.

I’m really happy with this, after cooking it noticed the air quality was worse and automatically kicked it. It’s made the rooms feel fresher and smell cleaner.I leave it on auto mode 24/7 and it’s great. Uses hardly any electric, around 10w on auto / low mode.
