Have you ever wondered what makes the Winix 5500-2 and Levoit Core 400S top-notch air purifiers? The answer is simple: extremely high-quality filtration technology, reliability, and numerous advanced features. I must admit I like comparing best-in-class air purifiers, mainly because those are very tough fights where the nuances decide.
I like that Levoit has plenty of features, such as an air quality sensor that detects dust particles in real-time, auto mode, a Smart app, etc. The Winix also has many features, but its air quality sensor detects only odors and cannot connect to the smart app. The Levoit Core 400S covers rooms up to 403 sq. ft., while the Winix 5500-2 covers slightly smaller rooms up to 360 sq. ft.

These two air purifiers use very high-quality filters, which are undoubtedly the most responsible for the exceptional results in performance tests.
Regarding design, I will give a slight advantage to Levoit because it looks more stylish and modern than Winix. The build quality, as well as the quality of the plastic, is okay on both devices.Today’s article will be an in-depth analysis of the Winix 5500-2 and Levoit Core 400S air purifiers. There can only be one winner, so keep reading to find out which one.

Both appliances are highly qualified for a throne in this comparison, equipped with plenty of advanced features. So, without further ado, I suggest we start comparing them one by one.
Air Quality Sensor
Located at the rear part of the Levoit Core 400S, AirSight Plus is a laser dust sensor that detects real-time PM2.5 particles. You can check this information at any moment, either through data displayed on the panel or by using a Smart App. And, as long as you keep your air purifier plugged in, this sensor will keep running.
Contrary to Levoit, Winix 5500-2 has an air quality sensor restricted only to odors. This means it cannot detect general particles, such as dust, pollen, or so. Strictly odors. For this reason, I recommend this air purifier mainly to customers who are active smokers or like to spend a lot of time in the kitchen. Winix can handle it.
Air Quality Indicator
Relying on the sensor an air quality indicator will light up according to the real-time pollution. Levoit’s indicator can switch colors between Blue-Green-Orange-Red to let you know the current situation. On the other hand, the indicator within Winix has only three colors: Blue, Amber fair, and Red.
In both cases, the higher the pollution, the indicator color will get closer to the Red.
Many air purifiers do not have the Auto mode feature, but Levoit Core 400S and Winix 5500-2 do. Combined with the Air quality sensor, you get an air purifier you can lean on.
What Winix air purifier has is a bit restricting Auto mode that relies on an Air quality sensor. But since sensors can only detect odor particles, this feature will suit you best if you like to spend a lot of time in the kitchen or if you are a smoker.
Nevertheless, in both air purifiers, the air quality sensor will make the air purifier switch between speeds while running in Auto mode.
Having a Sleep Mode option can be of great aid, for users who like to keep the air purifier working during the nighttime. Good thing both of today’s air purifiers have this feature, and in both cases, this Mode is separate from other fan speeds.
I’m going to start by saying a big WOW to the Sleep Mode that Winix 5500-2 owns. Incredibly silent, with barely-there lighting indicators, this Mode will make sure nothing gets in the way of your sleep.
Compared to Winix, Levoit 400S has a bit less silent Sleep Mode, but not in an annoying kind of way. You can leave it running day/night, and you will be pleased with it.
The Night Mode is a bit of an add-on to a Sleep Mode of Winix 5500-2. If you set the air purifier to Auto mode, the appliance will switch to a super-sensitive machine that detects the level of light in the room. It means that in case the room is very obscure in light or completely dark, the Auto mode will switch the Winix air purifier into Sleep mode. This will make the appliance more than adequate for your sleep.
If you take a closer look at the Control panel of Winix 5500-2, you will see a Plasma Wave indicator. Plasma Wave stands for technology used in the air purifying process. Once you turn this option ON all harmful particles will be continuously removed.
Once it is activated, the indicator will light up. No worry for those of you ozone concerned, because Winix is CARB certified, which means the amount of emitted ozone is below the danger line.
Both Levoit and Winix have a Timer option. If you want the Core 400S to run without interruptions, you can set it within the 12h-range. You can monitor this feature by using either the panel button or the App. At the same time, Winix 5500-2 allows you to choose between 1h, 4h, or 8 hours of continuous running. You should try it.
Smart App (VeSync)
A great deal for most products nowadays is a Smart App connection. One of those products is the Levoit Core 400S. The VeSync App is the Smart app you can use to control this air purifier in a way to monitor all the features and functions this device has installed by default.
Even though Winix is a great air purifier, it’s still missing this option.
Yes, I know, having another remote control on your living room table will probably seem like piling unnecessary things, but this is quite a helpful gadget. If you buy Winix 5500-2, the remote control comes along. It is small, simple, and easy to navigate, and the best thing is you can use it to control almost every single feature on your air purifier.
There is no remote control for the Core 400S, but hey, you can use the VeSync App instead.
The Screen off option is available only in Levoit Core 400S, and it’s a great feature if you wish to use your air purifier in your bedroom during the nighttime. Once the Screen Off option is ON, this feature will dim all the lights and indicators on your appliance. All except the filter reset indicator.
The Lock Screen is a protective option, meaning it takes a 3-second finger press to lock/unlock this feature. Once locked, nothing can get in the way of your air purifier. Even if some noisy guest tries to interfere, nothing will happen. The good thing is even if you lock your air purifier, you can still control and use it through the VeSync App.
Filter Reset Indicator
One of the most advantageous features an air purifier could have is definitely a filter reset indicator. It releases you from the duty of predicting whether and when you should replace the filter in your new favorite device.
Levoit Core 400S has this indicator built-in, and you can completely rely on it to alert you in due time to replace the True HEPA filter. It usually takes 12 months before replacement.
Winix 5500-2 also has this feature that alerts for both True HEPA and AOC Carbon filters. The replacement takes place once a year.
At first sight, the shape difference between Levoit Core 400S and Winix 5500-2 is more than obvious. While Levoit is cylindrical, Winix is more rectangular in shape. Within Levoit, filters follow the shape of an air purifier, hollow in the middle. The air inlets are spread all around the air purifier on the bottom side of the unit.
Once the air runs through the filters, it gets out through the grills on top. Winix, on the other hand, has air inlets on the front side, but on both sides as well. After the air is purified, it gets spread through the holes on the upper side of the air purifier.
Since both Levoit and Winix are well-known and respectful brands, warranty coverage is available for 2 years within the purchase date. There are no specific conditions regarding claiming your customer rights from Winix. With Levoit you will be way more efficient if you register on their website after you purchase the product.
Filters that both Levoit Core 400S and Winix 5500-2 use are quite similar, with the exception that Winix has an extra fourth filter stage.
The Levoit has a basic 3-in-1 filtration process: Pre-filter, True HEPA, and an Activated Carbon Filter. On the other hand, Winix has a Pre-filter, AOC Carbon filter, True HEPA, and PlasmaWave technology. Let’s go from the start.
Standing on the first line of defense, a pre-filter is an important part of the filtration system. It serves to protect, mainly the second-in-line filter, from all the large particles such as dust, hair, pet dander, etc. Since only Winix has a washable pre-filter, it is highly recommended that you keep it clean by dusting or vacuuming at least twice a month. Preferably, every two weeks. That way you will protect and prolong the life of the following filters.
AOC Carbon filter is available only within the Winix 5500-2 air purifier as its second filtration stage. The good thing is this filter is a pellet-based carbon filter, the number one culprit for outstanding Winix performances in reducing home odors. And the best thing is, it is washable. As for the Levoit, the Activated carbon filter comes as the third and last filtration stage. Being also pellet-based this filter uses Levoit’s exclusive ARC formula, which adsorbs smoke, odors, and fumes but also unpleasant pet smells.
In my opinion, if you want a good air purifier, make sure it has a True HEPA filter. Both Levoit Core 400S and Winix 5500-2 have this filter, only as different filtration stages. While Levoit uses the True HEPA filter as its core and second stage, Winix has placed it in third place. This filter is responsible for 99.97% of removed airborne particles.
As for the fourth stage, Winix uses PlasmaWave technology, which I have written about in one of the previous sections, so jump over to see what is it about.
How To Replace Filters On Both These Devices?
No matter how difficult it may seem, replacing the filters in most air purifiers is a pretty much simple task.
With Winix 5500-2 all you have to do is to disassemble the air purifier the same way you assembled it after you purchased it. Good vacuuming is always recommended in maintaining the pre-filter, and this stands for all air purifiers. As for the AOC carbon filter and the True HEPA filter, you can easily replace them with new ones, approximately once a year. Maybe even more often, if you really use it.
Replacing Levoit’s filters is an easy job to do since all you have to do is take out the filter tube and replace it with the new original one – the RF filter. It takes about 12 months before you need to do this, but don’t worry. The filter reset indicator will help you on the way, as well as with the Winix air purifier.
In case you still need instructions, you can find them in separate reviews.
We’ve come to the most interesting part of this comparison. There is always something about the speed, even if it’s only an air purifier. Both Levoit Core 400S and Winix 5500-2 have five-speed options, including the Sleep Mode.
Speaking of the Sleep mode, Levoit is super quiet while operating at this level. However, Winix is even more silent, with only 40.6 dBA. Plus, it is also silent while on the first speed level.
With speeding up, Levoit tends to get louder, but Winix remains in continuity with being pleasant to the ears.
As for the last, Turbo mode, things start to change in favor of Levoit Core 400S. This is the maximum speed level, and with a 59.9 dBA, Levoit is way more silent than Winix with its 66.4 dBA.
|Product||Noise Range (dBA)|
|Levoit Core 400S||42.1 – 59.9 dBA|
|Winix 5500-2||40.6 – 66.4 dBA|
Overall, comparing both air purifiers, the noise never exceeded the tolerance level.
Okay, this was challenging. On one side, I had Levoit Core 400S, a member of an air purifier family that never fails and which promises a lot with its standard 3-in-1 filtration system. Opposed to it, on the other side is the Winix 5500-2 air purifier with a 4in1 filtration, including the PlasmaWave technology. Both air purifiers have 5-speed motors to run and prove their durability and good performance.
At first, I wanted to test both air purifiers in the same room size, the 320 sq. ft., but then I realized that Levoit can possibly cover an even larger room. So, I decided to give it a try with a 560 sq. ft. room size.
Both air purifiers were subject to a 60-minute long test and here is how it turned out.
320 sq. ft. Room Tests
Since Winix is designed for a 360 sq. ft. room and Levoit for a 403 sq. ft., this test should have been a peace of cake for each.
I had Winix tested in two modes, the Auto and the Turbo mode, both accompanied by the PlasmaWave technology ON. While running on Auto mode, Winix improved the air quality by 93%. But, while on Turbo mode, Winix has made even higher results with almost 96% air quality improvement.
In a separate test, I had Levoit operating on Turbo mode, and, by the end of the test, the overall air quality improved by an incredible 96%.
560 sq. ft Room Tests
As previously said, I wanted to test Levoit at an even larger room size, which is why I picked a 560 sq. ft. room size. Once the 60-minute turbo-mode test was over, the room air quality improved by approximately 91%.
At the end of the testing, I was more than overwhelmed by the results shown on all tests. However, this is a comparison, and I have to put one air purifier ahead of the other. This time it would be Winix 5500-2, for its amazing performance with a powerful 70W motor.
First of all, we have two amazing air purifiers, and it would be silly to expect them to be super cheap. However, the initial product price is not as important as the overall maintenance. To start with, the filter replacement rate is once per year. But, replacing the filter in Winix is far more expensive than in Levoit.
Last, but not least, comes the monthly electricity cost. Compared to a 38W motor that Levoit Core 400S has, Winix has doubled it to a 70W. That means if you leave both air purifiers running on Turbo mode for a whole month, day and night, Winix will give you a 5$ bill, while Levoit only 3$.
|Product||Wattage Range (W)|
|Levoit Core 400S||0.9 – 35W|
|Winix 5500-2||3.7 – 57.9W|
At the end of it all, I find that the Winix is a far more expensive appliance to own. Levoit’s costs are reasonably lower.
Winix 5500-2 Vs Levoit Core 400S Video Comparison
Which One Does It Better?
As I mentioned earlier in the intro, this is a tough battle in which nuances decide the winner. Before announcing the winner, I would emphasize that whatever air purifier you choose, you won’t make a mistake.
However, as a better buying option and an absolute recommendation, I pick the Levoit Core 400S air purifier. The reason for this decision is that Levoit has so many advanced options, smart app option, an air quality sensor that detects dust particles in real-time, and because of more affordable maintenance.
I can say that these devices are almost equal when comparing all the other parameters.
