Levoit - Core 400

I have a Levoit Core 600 and Core 400. I think they work pretty well, but my air quality is pretty good already. Both purifiers turn the fan to a higher setting when I'm cooking, or if I have scented candles burning for a while. If I leave my front or back door open, it indicates lower quality air, and adjusts the fan speed if necessary. My furnace/AC filter was unusually clean after 3 months of use, and I attribute that to these purifiers. I like having them.

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. 

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.

We have 2 Levoits, 400 in the family room and 300 in the bedroom. Happy with them.

I enjoy the levoit. I believe I’d have the 400 model which is the biggest, but there are small versions. Tells you how bad the air is while it’s on and the filters last several months before having to be replaced. Noticeable difference when it’s on vs off.

My only complaint with my two Levoit 400s is that I can’t specify the air quality range for “auto”. It is hard coded with AQI values that make sense for Beijing, but not for the US. Auto only ramps up when we get a *lot* of particles (from cooking) but is just fine with levels the EPA considers unsafe for some sensitive groups.

The "Core" series (round ones) are definitively NOT HEPA. They still clean air, but if the certification is important to you, they definitely failed to get certified and misled their customers. Their "Vital" series (rectangular) is still HEPA, but they've backed off from marketing it that way due to their legal woes.

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 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

Worldtech. Very popular online. 900 baht includes filter with pm 2.5 indicator. Gets 90% of the job done at 1/3 of cost.

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.

Levoit are consistently ranked among the top by professional reviewers and customers alike. There are people out there who are all pissy about the fact that the filters aren't officially HEPA certified anymore and have made it their life mission to shit on Levoit at any opportunity, but the fact is that it's just not important as the filters are still among the best performing, with or without the certification and it's wholly irrelevant for most people's uses. My main advice would be to get the largest unit you can afford, as small ones are much less effective. Large ones can always be run on a slower speed if put into a small room, but generally it's best to use the highest speed you can handle without being annoyed by it. The Vital 100S and Vital 200S have washable mesh pre-filters which is one of their main advantages over the Core series, but the Core series are still very good. The washable pre-filters just help keep the primary filter lasting a little longer between replacements. However, reviewers have noted that the Vital 200S is the better choice over the 100S due to being quieter, more power efficient, and larger. The Core series have a non-washable pre-filter which you can vacuum every couple of weeks with a soft brush. They are still excellent purifiers, and there are plenty of options for third-party replacement filters which are just as good, but cheaper than the originals. There are also good third party filter options for the Vital series as well. Since an air purifier is designed to be turned on and left running constantly, the smart features aren't really necessary unless you would like to control the speed every night when you go to bed, or set schedules where it runs at maximum when you're out, and then returns to a lower speed when you're home, etc. Other than something like that, the non-smart enabled ones will do just fine. Also remember that the room sizes they claim can be purified are exaggerated greatly for all brands and models. The really small units which can fit on your night table by the bed and sell for cheaply won't be very effective.

Hey! I have 5 Levoit smart purifiers around my home on Google Home ecosystem, and it works flawlessly.

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 had one Levoit Smart Air Purifier in every room of the house for several years now. I initially bought a few and but was uneasy about the expensive investment I was getting myself into. But I ended up liking them so much I kept getting more and more. I have no regrets even though I’ve spent over $1500 total on them. They make a huge difference (home for a small family + several pets). Actually only regret is I didn’t do this sooner. I’ve suffered from allergies most of my life, to the point that I always walk around 24/7/365 with giant wads of tissues in my pockets. These things make it much more bearable. Pro-tip, you can prolong the filter life by vacuuming the gunk off them. Probably should do it outside as the vacuum tends to agitate some smaller particles in the air.

I have recently purchased a Levoit core. Although it is early days, maybe a week or so, the air feels cleaner in the room it is in. I may in the future, purchase one more. I will be purchasing the same brand. No complaints so far.

I got a Levoit Core air purifier a few months ago and have been happy with it for odor control. I primarily got it as a couple friends are allergic to my cat and have suffered when visiting 😂 happy to report it’s been great in that regard, too
