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

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.

I have been using the 400s in my bedroom for about a month now, and it's definitely made a difference. I've noticed less dust settling on things, and the air just feels cleaner when you walk in.First impressions? It's a fairly big machine, no getting around that, but it needs to be for the size of room it can handle, (overkill for my room of 23m). Even though it's large, it looks quite modern and sleek, so it doesn't look out of place. Setting it up was simple enough, just taking the filter out of its packaging and plugging the unit in. Connecting to the Wi-Fi app was straightforward too. The app itself is quite useful if you want to fiddle with settings remotely, put it on a timer, or check the air quality readings it’s been getting.As for how well it actually works, it seems to do a good job. It has the usual three filters: one outside for bigger bits like fluff and hair, the main HEPA one for fine dust, and a carbon filter for smells. The sensor that checks the air quality seems pretty sharp. If my neighbour is smoking near an open window or if there are strong cooking odours lingering, the purifier detects it quickly and the fan really ramps up. You can also tell the air quality at a glance from the coloured light ring on top, which goes from blue for good to red for bad.When the fan does kick up to full speed because it's detected something, it is pretty loud but works quickly. But on auto and lower mode, it's generally quiet and unnoticeable, same with sleep mode.Maint for it is easy too. The main thing is to give the outer pre-filter a quick hoover every few weeks to get the dust off, plus a wipe down of the machine itself. Doing that should help the main filter last a bit longer, since they costs like £60, this help to extends it from 6 months to maybe 8.The only real grumble is that you can't recycle the old filters once they're done. It makes sense given all the stuff they trap, but it’s still a bit of a shame not to be able to. And obviously, its size means you need a bit of floor space for it.I got it on sale for £190 and it's decent so far. It clears the air well, it's easy to use day-to-day, and the app controls are handy. Even with the noise when it's going flat out and the filter situation, it's a solid 4 out of 5 stars. Definitely worth considering if you're bothered by dust or allergies, they have a variety of filters too for different use cases.

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.

I have been using it in a relatively smaller room that what the filter is capable of servicing. It works great and fairly quickly. The PM 2.5 meter is more sensitive than my air quality monitor and brings down the reading rather effectively.App and Alexa control work very smoothly.Fan is not very loud. Sleep timer with sleep mode works very well.The setup is light in weight and the lights on the controls can be turned off as well.Overall very happy with the purchase.

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.

Very quiet and highly sensitive to air particles

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.
