Buy the Levoit Core 400S on Amazon: amzn.to/3hESFUN If you have any questions, please feel free to comment below, and I will do my best to answer as soon as possible! 😊

This is by far the best YT channel I've seen regarding Air Purifiers! I've decided to go with this over others of this price range. Thanks for the great videos!

I have one of this, can confirm it is silent even at High fan speed (Turbo gets a bit loud but nothing unbearable), especially compared to a Mi purifier, which sounds like a jet engine.

If you’ve never used an air filter these are great. kzfaq.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. I noticed the air seemed lighter and easier to breathe when running the machine for the first time. Works great every time. Highly recommended!

Amazing 15 seconds to clear smoke, great machine

Bought this on Amazon last night and received ut this morning. It is very sleek and sturdy. You cannot hear it at all which I love. I bought this for my dog who has very itchy and I have to take her to the vet every 6 weeks for an allergy shot. Hope this helps to relieve some of her itchiness. We'll see. Edit: I really did my homework on air purifiers and this fit my budget and needs.

Do the core 600s next! Love your reviews!

Levoit is a fantastic brand. I made the mistake of getting their Vital 100 model for a much larger space than it is rated to cover. I have an open floor plan and 12 ft high ceilings. I've heard very good things about the Core 400S.

These air cleaners do reduce dust. Well, Ive been using Honeywell Power Series for a few years. I like Honeywell. I bought the Levoit one here so I can use the smart feature to turn them on/off in multiple areas. Honeywell has a turbo mode I love. I press turbo while cleaning to suction airborne dust into the filter. I can easily vacuum the dust off of the front black pre-filter on the Honeywell air cleaner. Now I ought to unbox the Levoit air cleaner to test and compare. I have to say again, the Honeywell Power Series air purifier has been a solid performer. Ive had them running constantly for at least 3 years with zero issues. They're so fast to clean. Pop front screen off, vacuum, pop screen back on. Done. Change black pre-filter every 3-ish months (easy), and change HEPA filter, I think every 6 or 12 months. The unit has a timer, and the red change light on top will tell you. Very easy. No major disassembly. They just lack a smart feature so I cannot remotely turn them off/on like this Levoit Plasma Pro 400S. But, if I were to advise Honeywell, I would tell them to please don't mess up their already good design on the Power Series air purifiers. They could minimalist simple add some type of smart feature to switch it on/off remotely, and add a simple app to monitor. But change nothing else, because it works so well! Ok, let me unbox my Levoit now to compare.

Thanks for the video, wish my first filter lasted a year! And that’s with the digital readout always under 5. Pricey devils!

Thanks for the review! Was waiting for this one and debating whether to get this or the coway 15122? Some notes to maybe improve your reviews: #1. Since this has a smart sensor, would be great to show comparison of the accuracy of it to an air quality monitor device. #2. Realistically no one will use turbo mode for long periods of time (due to noise), so how well does this device clean on manual mode when it's on 1 step or 2 steps below the max speed? #3. Comments compared to other air purifiers in the same range (price, area coverage, cadr rating, etc)?

Great video! It seems Levoit has removed the TrueHepa claim from their website and marketing, there is a Reddit thread about it. Can we confirm that they use a TrueHepa filter for the 400s?

My recent experience with their Customer Service was horrendous. This unit is not AHAM certified.

Please could you review the Levoit Core 300s and the Levoit PUR131s? They seem very similar in spec, just have a different shape. Which would you recommend from those two choices? Thanks!

What’s a good budget smart air purifier? P.S. Your a very underrated KZfaqr

Hello mate. What would you recommend between the Levoit Core 400S and the Xiaomi Purifier 4 Pro. Xiaomi stands out in by having ionizing tech, a larger motor, allegedly longer filter life (debatable of course) and being a bit quieter (or that's what I've read). Price range very similar. Awaiting your input.

Thanks for the detailed review, i ordered one because of this! Could you describe though how big of a difference there was in pm2.5 between your handheld device and the filter sensor?

Can ‘Smart’ feature be disabled? Or only enabled with the app? I’d like to only use it manually with no WiFi. Thanks!😊

I'm looking to get one and this seems like one of the quietest. I am mostly interested in the low noise at night but I heard that some still have some "buzz" from the motor, not necessarily the fan. Is this true? Did you hear any kind of sounds? Also, how can Levoit claim in their product page a noise of 24 dB but your readings are much higher? Awesome videos btw.

I need TURBO power HEPA filtration and smart remote access of the control panel to on/off from a completely different room. If it has this, I want one like now!

I have been using this product for half a year and have not removed the plastic bag from the filter.

How does Levoit compared in performance / efficiency vs. Xiaomi 3H ? Thanks, love your channel , very informative

This is a really good one.

Hello! I have a question. My room is quite small ~ 100 feet square, because of that I want something with lower noise. I can t decide between levoit 300s and 400s. I was thinking to buy levoit 400S and leave it on speed 1. I think should be enough. which model should I choose between these two?

will this get rid of marijuana smell and smoke

Thanks for the detailed review, will be subscribing. As you may know, there exists the PlasmaPro 400s. Would you say the ionizer is the only key difference between the two? Also, between this model and the Winix AM90, which one would you say has a better performance in terms of capturing viruses when placed in mid size rooms? Thank you for the time.

Hi, for a 280 sqft bedroom do you recommend the 400s or the 300s? I'm getting this mainly for the dust particles in the air, don't care about smoke. I know the 300s size says for 200sqft , but I was wondering if 280 sqft is okay too, if not then I would have to get the 400s. At night, when sleeping, I would prefer to use night-time speed or even speed 1, would your recommend the 300s or 400s for that?

I have one and it got rid of the ferret smell very quickly.

I received the levoit 600s yesterday and i test it out in a bedroom maybe 250ft2 to 300ft2 and had it on sleep mood it was very quite and I definitely can feel and smell the clean air across the room and I have my coway 300s in the living room also on sleep mood , I woke up 4am felt like I have dry through and nose and I immediately turned it off both unit and my wife in the morning says same thing. So I’m wondering is that normal feelings since we’re first time using a purifier so my question is maybe it’s because a big purifier shouldn’t be left in a small room ? I live in apartment 900ft2 should 1 levoit 600s be enough for the whole apartment? Any advice would be greatly appreciated! 🙌🏼

So many purifiers BUT which one of these will help remove and possibly kill mould spores. I dont have mould at home anymore but it has become airborne, always feeling shortness of breath at home only

The best purifier reviews by far! thx for sharing!

I just bought one of these today. When scrolling through their questions and answers page, I’ve came across ionizer and ozone gas release information. I was not aware of these elements until I did some research. Ozone can harm respiratory functions… I would like to use this on a new born baby’s room. I am looking for thoughts on this or more insight- its very confusing and strange . I would appreciate it !

Did you record the video with a VGA camera from the 2000s? The image is shaking is poor.

Hi, I would like to know your opinion on the best air purifier for a room of more or less 30m2 with a lot of wood: Xiaomi Pro H or Levoit 400S? One of my focuses is getting odor out of the room and fresh air.

Good day.. New subscriber here from the Philippines.. Love your videos and reviews.. But just wanna ask suggestion from you, what should budget Air purifier should i buy for small room?

How do I get the top off? There is no handle or anything to grab on to.

is the built in air quality sensor accurate compared to your hand held device?

Why can't I connect my Levoit 400 to Alexa ? I heard that Amazon disabled this process

So I just got mine. First impressions - bad. I had sprayed a parfume right at the air sensor. For some reason the PM indicator increased a bit but in auto mode it did not turned up the fan speed. Next, I put a smoking piece of paper next to it. The PM jumped at once to maximum but in auto mode, it did not turned up the fan speed to maximum, I had to manually select the 4th speed. I suspect that with that these air sensores are indeed of pure accuracy and one should not use auto mode but select one constant fan speed at all times. What is also inaccurate is the PM 2.5 level of 50 at which the device turns on the speed if in auto mode. The general standard is

Hello, does this filter hold the mold stories? The 300sha a filter only for mold? Is there no need for this model? Thank you

Why my device always display number of PM 2.5 is “1” after 1 hour (filtered). Any problems? Why it can’t back to 0?

Hi, thanks for the video review. Can you please confirm if the carbon filter has pellets in it or just a sponge-like material?

Hello, I would like to buy an effective air purifier for my small room which is 30m2. I am stuck in between Levoit Core 200s and Levoit Core 400s. Which one would you recommend?

So do the 300s, 400s, and 600s all perform about the same and just different sized for bigger spaces? I have the 300s in my bed room and was thinking of getting the 400s or 600s for my living room. Plus they are Prime Day specials right now.

Can I use it in a small room?

would you consider reviewing some iqair or austin devices?

This one vs Coway Airmega AP-1512HH? I'm looking at both, and both are the same price. Seems like this one has more tech features and better warranty, but I'd love to hear your opinion!

Is this better than say Dyson HP09, TP07 etc?

Hey! Just purchased it. What humidifier would be good with it?

will you be doing a review on the core 600s? it's on sale right now. Curious how it fares against the blue 211+ since they have almost similar airflow rate (m3/h)

Review xiaomi air purifier 4 lite pleaseee

i’m interested but is filter washable for this model? Thanks

Would you buy this Levoit core 400 or the Hoover 500?

Awesome job! Can you please review the Xiaomi Mi Air Purifier Pro H?

I just bought the 600s . It is very loud . Did they update the sound ? I love it otherwise .. but it's very loud and scares my cat

Hello. Will it purify a two floor house if left only on the downstairs floor??

I have 14 sq meters bedroom. Is it too much to use 400s? or I should get the lower version. I am looking for higher CADR. My concern is I have a kid and he sometimes get sick. Should I use the low fan speed

What do you think about the levoit core 300s?

Is it OK if I can place the Core 400S only 12 feet away from anything on all sides? I don't have enough space in my room for 15 feet.

Is it loud? I like to keep mine on medium.

Xiaomi mi 4 pro Levoit 400s hangisini önerirsiniz?

May i use it in auto mode when i sleep?

Why is my #666 or #999 and the circled lights around it are red

Does it work with 5Ghz wifi?

Why does this video say the filter can last a year but mine only lasted 4 months before saying I needed a new one?

I have one, filter life % go down day by day even the plastic cover for the filter still not remove yet. So, do they liar???

Can you test the b-mola I'm 100 please.

Does this emits ozone?

Not 15 centimeters! You mean 15 inches.

There is no engine…: it’s an electric motor. These are never referred to as engines!

You shoukd verbally state the negatives as many people will just listen and not even notice. This sounded more like an paid advertisement than an actual review. I also noticed you mentioned price of electricity which is going to vary wildly but didnt even mention the price of the actual unit nor even compared it to any similar purifier.

This review was useless to me. You rushed through how to lift the black piece off as if by magic. Mine won't come off. DIagram indicates to unscrew it but it won't turn.
