LEVOIT Air Purifiers for Home Large Room Up to 1980 Ft² in 1 Hr With Air Quality Monitor, Smart WiFi and Auto Mode, 3-in-1 Filter Captures Pet Allergies, Smoke, Dust, Pollen, Core 400S, Gray

The media could not be loaded. After using the Levoit Core 400S for several months, I was so impressed that I recently purchased a second unit for another room in my home. This smart air purifier has exceeded my expectations in every way.Powerful PerformanceThe Core 400S delivers exceptional air purification with its 3-stage filtration system that includes a pre-filter, H13 True HEPA filter, and activated carbon filter. This combination captures at least 99.97% of airborne particles as small as 0.3 microns. In real-world testing, it reduced PM2.5 particulate matter by 96% in just 60 minutes in a 320 sq. ft. room.What impressed me most is how quickly it responds to changes in air quality. When cooking creates smoke or odors, the unit immediately ramps up to tackle the problem. The air quality indicator rings provide an intuitive visual of current conditions, changing from red (bad) to blue (very good) as it works.Smart Features That Actually HelpUnlike many "smart" appliances with gimmicky features, the Core 400S's connectivity genuinely enhances its functionality. The VeSync app allows me to control settings remotely, check filter life, view air quality history, and create custom schedules6. I particularly appreciate being able to check my home's air quality when I'm away.The built-in AirSight Plus laser dust sensor continuously monitors air quality, displaying real-time PM2.5 readings on both the unit and in the app. This data-driven approach helps me understand my home's air quality patterns over time.Thoughtful DesignThe Core 400S strikes an excellent balance between power and aesthetics. Its sleek cylindrical design blends seamlessly into my home decor rather than standing out as an eyesore. Despite its powerful performance, it maintains impressively quiet operation - just 24dB in Sleep Mode, which is quieter than a whisper.With five fan speeds plus Auto and Sleep modes, it adapts to different situations throughout the day. The Auto mode is particularly useful, as it automatically adjusts fan speed based on detected air quality.Why I Bought a Second OneAfter seeing the dramatic improvement in air quality in my living room, I couldn't resist getting another for my bedroom. The combination of powerful filtration, quiet operation, and smart features made it an easy decision. At around $220, it's reasonably priced for the performance and features offered.The Core 400S effectively covers rooms up to 403 sq. ft. (or 92 sq. m.), making it perfect for most living spaces. With two units strategically placed, I've noticed significantly less dust throughout my home and improved sleep quality.If you're considering an air purifier that combines powerful performance, smart features, and reasonable pricing, the Levoit Core 400S is absolutely worth the investment - perhaps even twice.Please note, in the video, my phone is directly over the wind from the purifier which makes it a bit noisier than normal. I've had this for over a year now and it's still working great. I need to give it a his cleaning. Before the video, I had candles burning, it's steadily working to improve the air quality as it's being polluted.

Bought this several months ago and the sale price made it a bargain. We keep ours on automatic all day and switch to night setting at night automatically using the app. After a few months the original filter still has plenty of life left. Air is fresher, helps with dust allergies, and the high setting clears out smoke and bad smells quickly. It’s a bit larger than we expected, about knee high and maybe 11 inches in diameter, and it needs clearance around it to operate, so keep that in mind when you’re choosing. But we’re quite happy!

I have pets so I really want to keep the dust and allergens to a minimum. I like the sensor because it can detect cooking fumes and smoke. I’ve been using the auto speed select feature and most of the time it runs on low. On low, it’s as quiet as a mouse. It’s easy to vacuum the filter, when it needs it.

Works wonderful.

This is one of the better purifiers I've tested. The only thing I don't like is that you have to turn it upside down to change the filter.

We have a very large room that is only heated in the winter by a wood burning stove, and for some time I have noticed that it gets smoky - guess for the past few years, I'd just gotten used to it! I also was getting a dry cough in the morning, so the first thing is I got the water back onto the stove because I had let the humidification of the room go by the wayside. That didn't seem to help my dry throat so much. But this unit - wow. I cannot smell any smoke, it is SO QUIET, and I love that you can turn the blue light off at night. I use it in the bedroom at night which is on the same floor as the large room, then put it in the room during the day. No more dry throat and cough and the whole upstairs just feels clean. The Levoit got very good reviews, the cost was reasonable, and so I want to add this positive review! I HIGHLY recommend it!

I just bought this a couple of weeks ago, so far so good! Depending on the setting it can be noisy, but overall on the auto, once it's a good level of air is pretty quiet. It does clean/purify the air very well and quick. We're in a cabin with a wood stove that can be smoky at the start of a fire and it cleans it right up. And we've now also cooked with onions (small space no vent) and it also cleaned the air quickly.

Great device, i've had it for several months now and no complaints what so ever. The fan is super quiet even at night. All the light will turn off on the device so they dont distract. The purifer is even filtering out my air fresheners, i can even smell them. Just as a reminder, dont be like those on the internet and forget to read the guide, remove the filter from the bag before use.......
