Levoit - Core 400S-P

Levoit’s Vital 200S and Core 400S are great units. I picked up a Vital 200S per recommendation of RTINGs.

We have both of these too and love them

I use Levoit Core S400's. They work really well and 3rd party replacement filters are super cheap on Amazon. They use a cloud-based integration but I've never had it fail. I think I've opened the Levoit app maybe three times in the past year. https://preview.redd.it/izjfok2yrrhe1.jpeg?width=680&format=pjpg&auto=webp&s=72f36d43931d8666ad3fdb8c5df4191645594fe1

I use the VeSync Core 400s through Homebridge. A little big but they’re very good, and whisper quiet on the lower settings.

We use this large one for our open living space downstairs: LEVOIT Air Purifiers for Home Large Room Up to 1980 Ft² in 1 Hr With Air Quality Monitor, HEPA Sleep Mode, Auto Mode, Smart WiFi, 3-in-1 Filter Captures Pet Allergies, Smoke, Dust, Core 400S-P And then we brought the smaller one for our daughters bedroom. I’ve definitely noticed a difference in the dust in our house, especially when we leave the windows open. When the wildfires were burning in Canada our area got really bad smoke and I truly feel like it helped. The light turns a different color if it detects pollution or smoke in the air so it’s a good way to keep track as well. Also when we change the filter I can’t believe how much dust is stuck to it! I figure it can’t hurt to have one!

My recommendation for price/performance USED to be the Taotronics TT-AP003, but unfortunately, it looks like it was discontinued :( All units with HEPA filters have basically the same filter, so don't overthink it. However, the ONE SPEC that matters is [CADR (Clean Air Delivery Rate)](https://en.wikipedia.org/wiki/Clean_air_delivery_rate) - this measures how MUCH air it filters. Manufacturers don't like to advertise this unless it's good - likely because their smaller/worse air purifiers wouldn't sell as well! Also note that the advertised CADR is only at the highest (aka *loudest*) fan speed. *For less noise, it's better to get a larger filter and run it at a lower speed - you don't want a little hurricane in your bedroom all night!* Here's some commonly recommended filters (and some from this reddit thread): * The [Levoit Core 300](https://levoit.com/collections/air-purifiers/products/core300-air-purifier) has a CADR of 135 CFM for $99. * The more expensive [Levoit Core 400S](https://levoit.com/products/core-400s-smart-true-hepa-air-purifier) has a CADR of 260 CFM for $219. * The Wirecutter-recommended [Coway Airmega AP-1512HH](https://cowaymega.com/products/mighty-ap-1512hh?) has a CADR of 232+ CFM for $168 (price as of today) - not a bad deal! * The [Winix C909](https://www.costco.com/winix-c909-4-stage-air-purifier-with-wi-fi-%2526-plasmawave-technology.product.100842491.html) has a CADR of 323+ CFM for $199 (Costco online price). Also seems like a good value. * The [Winix C610](https://www.costco.com/winix-c610-4-stage-true-hepa-air-purifier-with-wi-fi-and-additional-filter.product.4000295784.html) has a CADR of 245 for only $129 (Costco online price)! **Probably my recommendation for best price/performance for small/medium rooms.** * The expensive [Dyson HP7](https://www.amazon.com/Dyson-HP07-Purifying-Heater-White/dp/B09LSMRKFD) bladeless heated fan and filter only has a CADR of 80 CFM for $599 (!) You'll notice that filters of similar size have similar CADR. That's because they're essentially a HEPA filter and a fan - it's hard to improve filtration without a larger fan or larger filter. The differences come down to noise level, build quality / customer support, features, and cost of replacement filters. Cheers!

We bought multiple units of Levoit Core 400s (1 per room, higher-ceilings). We are very happy with the result. Keep in mind that while the air may start improving immediately, many of the symptoms you feel may take a few days to disappear. In my case, in particular, I stopped taking my daily dose of antihistamine starting 4 days after the Levoits. That was in September 2024.

We bought multiple units Levoit Core 400s in January 2024. Quite satisfied in terms of value for money, operation options, and upstream costs.

I second this purifier. They're great.

I've went through over a dozen air purifiers in the past ten years. I've come to love Levoit. I have the Levoit 400S-P. And i can control it with my phone which is nice.

I have a Levoit. Some have the ionizing feature and some don’t. This is the one I have. LEVOIT Air Purifiers for Home... https://www.amazon.com/dp/B08R794ZMX?ref=ppx_pop_mob_ap_share

Yeah the 300 is smaller, just read the description carefully and don’t get the ionizing version, they look extremely similar :P

I figured it out, sorry it’s been over a year… Ok Levoit calls the ionizing feature “Plasma Plus”, the first one I bought at the store Target had that, I returned it and got the one on Amazon which does not have Plasma Plus, here is a screenshot of the Plasma Plus box. So if you buy one without “Plasma Plus” it should be fine. (Also supposedly the plasma feature can just not be turned on but I wasn’t taking any chances) Edit: sorry it’s Plasma Pro not Plus https://preview.redd.it/q8w2eb6ukhgd1.jpeg?width=750&format=pjpg&auto=webp&s=7f5f3eb917b24c06495c2ba7d9d52ceaa71f3966

I have a Levoit. Some of them have an ionizing feature, I assume as long as you don’t use that it will be fine (I wasn’t taking any chances though and got one of the models on Amazon that don’t even have that). They call the ionizer “Plasma Pro”, so it will say that on the box if it has it.

We have a bunch of Levoits in our home: two Core 300, two Core 400s, and now a new Vital 200s. We also have a Coway Airmega AP 1512HH and a BlueAir 411. Levoit has great customer service and a two year warranty that they actually honor if you can prove via video that your unit went bad. That being said, I’ve actually had to use that warranty 3 times! The fan of one 300s started making a whirring sound about a month into owning it so they sent a replacement. That replacement started making a far worse sound in about another two years (the warranty is only from the first date of purchase). Less than two years in, the fan of the air quality sensor on one of our 400s started making a grinding sound and gave off a burning smell. They sent a replacement right away. I still like Levoit because of their customer service and I wanted try the Vital 200s because of the pellet carbon to deal with morning-to-night hotboxing neighbors. The Airmega has been a workhorse but I wish it had more than the cutesy carbon mat for VOC removal (much of this sub will tell you that unless you have a lot of activated carbon pellets, like lbs of them, then you don’t have much hope with VOCs). This is true, all of these purifiers running all of the time and the weed odor is still pretty bad. I’m thinking of getting the Oransi TrueCarbon to deal with that.

Yes, the Levoit Core 400S (which is particulates-focused) should be adequate as it has a Smoke CADR of 231 CFM. That's assuming you don't get a massive wallop of soot or smoke particulates. Keep in mind that CADRs are given for the highest speed setting only. CADRs can drop off significantly at lower speeds. As for gases/vapors/odors, it will depend on your budget. The heavyweight sorbent media smoke purifiers like AllerAir and Airpura are very expensive ($935 and at least $1,099 respectively for their best models). They're also *loud*. With the [AllerAir AirMedic Pro 6 Ultra S - Smoke Eater Air Purifier](https://allerair.com/products/airmedic-pro-6-ultra-s), you should get approximately 5 Air Changes per Hour (ACH) at 525 sq. ft. "Delivered" air flow is 290-310 CFM. The carbon canister weighs 32-34 lbs. I don't know the exact activated carbon blend in this purifier; you may want to ask AllerAir how well the carbon removes nitrogen oxides, sulfur dioxide, carbon monoxide, and carbon dioxide. For the [Airpura C700 DLX - Chemicals and Gas Abatement Plus Air Purifier](https://www.airpura.com/products/c700-dlx-chemicals-and-gas-abatement-plus-air-purifier), you get 5 ACH at 540 sq. ft. Air flow "with filters" (I assume this is delivered air flow) is 450 CFM. The carbon canister is 26 lbs. with what appears to be untreated activated carbon. But you also have the "upgrade" choices of potassium iodide (KI) impregnated carbon, potassium permanganate (KMnO₄) impregnated carbon, **or** a German carbon filter. Obviously you can save a lot of money building the AC Infinity setup, especially if you manage to buy your sorbent media in bulk. But I'm unsure how well KMnO₄ impregnated carbon or alumina handles gases like carbon dioxide or carbon monoxide. CO₂ is better removed with magnesium oxide (MgO) impregnated carbon *or* sodium hydroxide (NaOH) impregnated carbon. Carbon monoxide is more efficiently removed with certain copper (Cu) impregnated carbons; copper chloride (CuCl) is one such impregnant.

Thank you. Since driving an EV, the gases from other vehicles is extra disgusting. I've brought my Core 400S in the car a few times, but figured I'd research and here I am finding this subreddit, and activated carbon. 

Levoit come out well in lab tests. I'm in the UK and use a service (which.co.uk) that puts all different products under lab test to see how well they actually perform. I always check it first before buying any tech. Levoit seemed to come out the best for me at the time. We got the 400s I think it was called

I have Levoit 400S that I bought 2 years ago for a little over $219.99, now cost $179.99. I'm a dark mode guy and I hate noisy fans. I like my house mostly dark and I can't sleep with a lot of lights from smart devices or noisy fans. This Levoit 400s has the quietest fans I've ever heard. Levoit also has excellent filters with 3 types depending on your needs. I'm also allergic to Cannabis and cigarettes smokes and Levoit has 3 types of filters and the top filter that I buy is comparable to filtrete MERV 11 which removes most weed most smell odors. They also have an excellent customer service which solve one of my cons below. One of the cons of Levoit air purifier is that it works best for houses with floor vents because the purifier fan blows the air from the floor to the ceiling. Another con is the PM sensor which tells you your indoor air quality can go bad easily. Mine went bad in just 4 months and I contacted Levoit which asked me a minute video recording of the issue and they immediately sent me a whole new air purifier and said that they'll contact me later to send them back the defective air purifier and if they don't contact me after 2 months, I can get rid of it. They never ever contacted me. So I bought the sensor from China for around $17 and easily replaced it. After having two functional air purifiers for the price of one, I gave the first one to my friend. Update: I forgot to add that Levoit has a night mode when the fan spins at a speed that I can't hear if it's on or off and all lights are off when night mode is on. This makes the air purifier excellent for those that hate noise and lights while sleeping at night. I'll also add a pros that is the wifi connection is rock solid and the VeSync app easy to use. You can schedule the air purifier to start and stop at certain days of the week, at specific hours of the week. You can even turn it on and off based on schedule (I just spent more than $300 on Google nest thermostat 4th generation just released this 20th August 2024 and google home app cannot even turn off the thermostat based on a schedule). Another con of Levoit air purifier 400e is that it works on 2.4 ghz wifi only and you also need to enter the app to see how long you have left before changing your air purifier filter.

Bought Levoit 400s from Amazon a little over 3 months ago. We run it at night for 7 hrs. in our bedroom. Our home is fairly new and clean however after 3 months the air filter started emitting a terrible odor. I called Levoit about the issue & all they could say "maybe filter might have been old & setting on a shelf somewhere". Really no answer but they sent me a replacement one, no charge. These filters are supposed to last about a year if you maintain them. I'm not going to spend over 200.00 a year for filters

Hi everyone! I wanted to share the results of having an air purifier close to my ps5 in a small condo with 2 cats. I've had this console since launch and only opened it twice, each time there was barely anything to clean. I definitely recommend it specially if you have pets. The purifier I use is Levoit 400S but any purifier should help with dust and hair in my experience.

Another Levoit user here; I've got the 400S. Seems to do a good job. I've got it located in our main bedroom on the second floor. I can usually tell it's effectiveness when something is being fried on the stove downstairs...the air quality decreases significantly, then the purifier really gets to work and takes care of that.

Buy extra filters so you don't need to panic. Levoit air purifiers are good BIFL unless your electrical grid is shit. 300s is for portability but for main living room you may get higher ones like 400s.

I have a levoit 400s and I can generally get buy with blowing out the filter with my leaf blower. This may help you save a few bucks

I own a 400s and would not buy again. It’s really loud and there are much better options for the money. Replacement filters are also expensive where I live. Personally I will not buy another Levoit product as they have not been honest with customers about the HEPA status of their filters, not once, but twice.

We have a levoit 400s in our living room and it makes a huge difference for me, especially during allergy season. I vacuum the filter element once every week or two, and replace it every couple months. It's crazy how much crap it pulls out of the air. My gfs sister has pets and got one too. It made it much more pleasant for me to go over there. Way less hair and dust to irritate my allergies.

My Levoit 400s has been running constantly for almost a couple years and it’s going strong. So far I’d say it’s awesome.

Oversized hepas are better. It allows you to run them at lower speed and still get good air flow without all the noise. We run coway air mighties on level 2 in four bed rooms and levoit 600s on level 2 in the two large open spaces. If I were buying now I would probably get levoit 400s for the bedrooms because the smart rules and scheduling is helpful and they are often very cheap on Amazon warehouse. Noise is barely noticeable and the amount of dust they pull out of the air is shocking. Bonus that we never have to dust surfaces. They are also great to have during annual west coast wild fire smoke season and keep particulates in the house undetectable even when it has been horrid outside. Other good additions if your furnace can handle it is a merv 13 filter on the central HVAC. We also donated them to the kid’s schools that didn’t have them to help manage particulates, air bourne microplastics, and wildfire smoke there as well.

I like the levoits because they are programmable. Run at level 2 from 6am until 11pm but kick up to higher levels if they detect PM2.5. Then go into auto mode over night to save energy when nothing is getting stirred up. Bedroom ones mostly stay on 24/7 as they don’t have scheduling. The levoits pull 15 watts each on level 2. Running one 16 hours a day costs about $11 a year + changing a $50 filter once a year or so.

Get a bigger, stronger air purifier, or several smaller/medium ones. If one larger one (i have the Leviot 400s), place it in the most open spot in the house. The biggest problem with air purifiers that makes people think they don't work is that they often block the intake holes for the air by tucking them beside or behind furniture. To do it's best work, an air purifier needs the intake holes to be clear to take in as much air as possible. If you get 2-3 smaller ones, place them closer to the rooms the cat litter boxes are. Get the right filter for the air purifiers - many of them have specific pet scent filters that catch a lot more of those smells. How often are the litter boxes scooped? What type of litter is being used? How often are they fully emptied out and washed?(FYI, this should be done at the very least every month. I clean my three every two weeks) I have two cats and three litterboxes in a 1 bedroom apartment. I scoop twice a day, I use a clay based low dust cat litter and add a tablespoon of baking soda every day when I do my morning scoop. I have a large air purifier with a pet filter. When I have guests over, they have always commented on how they can't smell the cats and ask how I do that in such a small space lol.

Own Levoit 400 for our main living area (1,100 sq ft apt), the smaller one in our bedroom (toddler sleeps with us). Had them prior to Covid and love them. I vacuum the filters when I can per the manual. I got my mom the blueair 311i max because she was closer to one of the “minor” fires here in LA and she loved it so much she got the mini for her bedroom along with my dad’s (they sleep in separate rooms lol). I ended up getting the mini to bring to work.

Another vote for the Levoits! We have the 300s in each bedroom and a 400 in the living room. (Single story 1800 sqft, 3 bedrooms). It makes a huge difference with pets. We have cats and the air purifiers make the litter boxes unnoticeable. (3 Litter boxes get cleaned twice a week, this helps so I don’t have to clean them every day) We change the filters every 6 months. We even put one in the garage to help with musty smells. When the windows are open the are off, when the windows are closed they are on. We started with one and now have 5 🥰

We have a Levoit and love it, it has made such a noticeable difference. 3 settings, first one is quiet, the loudest one we use as a white noise machine at night.

We don’t have allergies but we do have a dog who has issues with shedding/dander and it has definitely improved the air quality

I bought a couple Lěvoit air purifiers, one has WiFi, I put one in the living room and one in the bedroom.

I really like the Levoit. It’s super quiet on the lowest setting and you can turn the lights off. My husband is a bozo who needs white noise to sleep so he always turns it up to its highest setting and then doesn’t turn the lights off. We have a coway airmega for our living area but I prefer the way the Levoit looks and my older son kept messing with the coway and it got stuck on a setting so I can’t turn it up or down. ETA I also have a roomba because I am allergic to dogs but my dog is my favorite child and I let him sleep on my bed during the day.

I have a Levoit Core series unit in each room. I can tell the difference when I run it- even visually, when the sun shines in the room I no longer see all the stuff in the air. They are reasonably priced, filters are easy to change, and have a nuce design.

How is a levoit only better for hair and dander? Hepa is hepa and vital series should be just as effective as the others. Core series is inferior. 

Yeah, as others are pointing out the pandemic is far from over. Air purifiers are a great idea. We have them in every room of the house. Get them to cover double the sq ft than the room you’ll use it in so that you can get the same coverage on lower settings. The Levoit Core series is good, has a small footprint and is pretty affordable. I’ve sent these to family. Shout out for the [Air Fanta 3Pro](https://air-fanta.com/collections/all) because it folds down and is portable for travel. [Clean Air Kits](https://www.cleanairkits.com/collections/shop-all) are also awesome. I just got the [Exhalaron](https://www.cleanairkits.com/products/exhalaron) to use for doctors appointments etc.

I chose the Levoit Core Series because its quiet operation worked well in my baby's room, and the cleaner air noticeably reduced my allergy symptoms.

So… I don’t know who told you that you only had to replace the filters once a year but 90 days is optimistic for a Levoit Core. And washable filters are a terrible idea, nobody makes a good washable filter. Just replace the Levoit filter whenever it gets clogged up.

I’d yank the Levoit units off this list unless cost is your biggest driver. While the Everest air is a good unit, the core is just not. It will clean air at first but it is cheap and the filter cost will add up over time. The lack of real pre-filters really kills these things. From your list, Medify is excellent. As is Coway 400. IQ Air will filter better than any of these units… but moves a lot less air doing so. I own one and I love it but I fully admit it lacks airflow and is VERY expensive. Alen is also good, you can optionally equip them with extra carbon which is nice. You won’t regret any of these purchases tbh.

We have several LeVoit smart purifiers and they’re outstanding. Our old home is super dusty and these units have made a huge impact on how we feel and no longer see tons of random dust particles in the air.

I have the Levoit smart air purifiers. We absolutely love them, and they make a huge difference when our friend visits with her dusty birds. Our eclectus isn't too dusty, but they also help with dog and teen boy smells too.
