It’s almost impossible to compare all Levoit air purifiers with one another, as the company releases a new model every few months. In this comparison, I’ll focus on two devices: the Levoit Core 400S, a medium-sized air purifier, and the Levoit LV-H134, a large air purifier.
Both are top-of-the-line, highly reliable, and extremely efficient air purifiers. They come with advanced features such as an air quality sensor, air quality indicator, auto mode, and more.
The Core 400S covers rooms up to 403 sq. ft. (37 m²), while the LV-H134 handles slightly larger rooms up to 492 sq. ft. (45.7 m²).
What I particularly like about these two models is the 3-in-1 filtration technology, consisting of a pre-filter, a main filter, and an activated carbon filter. This high-efficiency filtration technology significantly contributed to the outstanding performance of both devices in our tests.
However, the main question is: Which one is the better choice for you? I recommend reading this article to the end, where you’ll find the answer along with a detailed comparison of their specifications, test results, and other key features.
Our Verdict
After analyzing all the specifications and test results, I must say this was a tough battle.
Although the Levoit LV-H134 uses a larger filter and performed slightly better in some tests, I still think the Levoit Core 400S is a much better buying option for most people.
I would classify the Levoit LV-H134 as the better choice for large rooms, while the Levoit Core 400S is more suitable in almost all other situations.
The Core 400S is significantly more affordable to maintain, has more features, uses longer-lasting filters, and operates more quietly—all while still being exceptional at cleaning the air.

Performance Test – Comparison
Before getting to the performance test results, I should point out that both the Levoit Core 400S and the Levoit LV-H134 are designed for large rooms.
The Core 400S has a CADR of 260 CFM (442 m³/h), making it ideal for rooms up to 403 sq. ft. (37 m²). On the other hand, the Levoit LV-H134 has a CADR of 312 CFM (530 m³/h), making it most suitable for rooms up to 492 sq. ft. (45.7 m²).
Particle Removal Tests - Comparison
We placed the Levoit Core 400S and Levoit LV-H134 in two separate tests and measured their performance using the Temtop laser particle meter.
In line with their recommended room sizes, we tested them in various room sizes, but I think the tests performed in a 560 sq. ft. (52 m²) room are the most interesting.
After running at the maximum speed for 60 minutes, the Levoit Core 400S improved air quality by 91%, while the Levoit LV-H134 improved air quality by 94%.
These are impressive results for both air purifiers; however, due to its higher CADR and larger filter media, the Levoit LV-H134 achieved slightly better performance in this test.
Additionally, I’d like to highlight that the Levoit Core 400S improved air quality by 96% in a smaller 320 sq. ft. (30 m²) room.
Overall, the Levoit LV-H134 demonstrated superior performance in this comparison.
Smoke Box Test – Comparison
Basically, both Levoit models are top-tier air purifiers with exceptional filtration technology.
However, I believe the key factor influencing the smoke test results was the higher CADR of the Levoit LV-H134, which led to better performance.
This air purifier cleared all the smoke from the glass box in just 12 seconds, while the Levoit Core 400S took 15 seconds.
In essence, both devices achieved fantastic results in the smoke test, but the Levoit LV-H134 performed slightly better.
Noise Level Test – Comparison
As members of the Levoit family, both air purifiers have many features in common, especially regarding their operating modes: Sleep, Low, Medium, and High, with the addition of Turbo mode available only on the Core 400S.
As expected, Sleep mode turned out to be the quietest mode for both devices. The Levoit LV-H134 produces a sound of 41.8 dBA in Sleep mode, while the Levoit Core 400S produces 42.1 dBA.
Noise Levels - Comparison
Comparison of noise levels at all fan speeds between the Levoit Core 400S and Levoit LV-H134 air purifiers.
However, at maximum speed, the situation is completely different. The Levoit Core 400S produces 59.9 dBA at its highest speed, whereas the Levoit LV-H134 reaches 70.3 dBA, making it one of the loudest air purifiers we’ve tested so far. In fact, along with the Mila air purifier, it’s among the loudest tested.
| Fan Speed | Levoit LV-H134 (dBA) | Levoit Core 400S (dBA) |
|---|---|---|
| Sleep Mode | 41.8 dBA | 42.1 dBA |
| Speed 1 (Low) | 45.7 dBA | 43.6 dBA |
| Speed 2 (Medium) | 56.4 dBA | 47.8 dBA |
| Speed 3 (High) | 70.3 dBA | 55.4 dBA |
| Speed 4 (Turbo) | - | 59.9 dBA |
If you look at the chart above, it’s clear that the Levoit Core 400S is the quieter air purifier overall. The Levoit LV-H134 was quieter only in Sleep mode.
Operating Costs – Comparison
When it comes to operating costs, the first thing I want to compare is the power consumption of these two devices.
The Levoit Core 400S uses a motor rated at just 38W, while the Levoit LV-H134 uses a slightly stronger 45W motor.
Monthly Power Consumption Cost - Comparison
Comparison of monthly power consumption costs for the Levoit Core 400S and Levoit LV-H134 air purifiers at all fan speeds.
This means if you run these air purifiers continuously at maximum speed, 24 hours per day for one month, your electricity bill would increase by about $4.43 with the Levoit LV-H134 and about $3.06 with the Levoit Core 400S.
Not only does the Levoit Core 400S consume less power at maximum speed, but it also uses significantly less power than the Levoit LV-H134 across all other fan speeds.
| Fan Speed | Levoit LV-H134 (W + $/month) | Levoit Core 400S (W + $/month) |
|---|---|---|
| Standby | 0.3W ($0.03) | 0.9W ($0.07) |
| Sleep Mode | 3.1W ($0.27) | 3.3W ($0.28) |
| Speed 1 (Low) | 6.7W ($0.59) | 5.8W ($0.5) |
| Speed 2 (Medium) | 14.3W ($1.25) | 8.8W ($0.77) |
| Speed 3 (High) | 50.5W ($4.43) | 16.1W ($1.41) |
| Speed 4 (Turbo) | - | 35W ($3.06) |
In addition to electricity costs, filter replacement costs should also be considered. According to Levoit, the Core 400S filters last longer, and this, combined with its lower power consumption, makes it a much more affordable option for annual maintenance.
Features Overview
It is a real challenge sometimes to confront any two Levoit devices, especially since each new version arrives with advanced features by default.
Features such as Sleep Mode, Filter Reset Indicator, or Air quality indicator make you take it for granted while speaking of the Levoit Company. Let’s see all the shades between these two devices before you make a decision.
Air Quality Sensor and Indicator
Having an air quality sensor and an indicator is, for sure, one of the essential features any air purifier should have. How else would you know if or how much the air in your room is contaminated? As for these two air purifiers, the comparison is quite interesting regarding this feature.
I will start with the Levoit LV-H134, which has the air quality sensor located on the rear. This laser counter detects the real-time PM2.5 particles while working in sync with the air quality indicator. The sensor will display the number of particles straight on display, but the indicator will switch colors depending on the present pollution. Therefore, it can vary from blue, green, or orange to red.
The Levoit Core 400S also has an air quality sensor on the back side, and I am talking about the AirSight plus laser dust sensor. It can also detect the real-time amount of PM2.5 particles, which you can monitor via the VeSync app. The sensor works in collaboration with the air quality indicator, by expressing the air quality through the color of the indicator. In order for this sensor to work, you must keep the air purifier plugged in. That way, you can keep track of the air quality through the app, even if the device switches to standby mode.
Auto Mode
This enables your air purifier to switch modes and fan speeds, adjusted to the level of room pollution.
Both air purifiers have this option, but unlike Levoit LV-H134, which has a simple version of this feature, Levoit Core 400S has two other versions along with the simple one. There is a silent auto mode that will never make the air purifier run in Turbo mode, and there is the efficient auto mode which lets you set the room size. All these modes are available only through the VeSync app.
Sleep Mode
Having a Sleep mode is most definitely a great option, but having it as a stand-alone function is preferable. This means that the functioning of your air purifier will not be interrupted by any other feature. Both today’s competitors have this feature, and it works in a way that turns off the LED indicators and sets the speed level to the lowest. That way, you can freely use it in your bedroom through the night but in your workspace too, more so if you need deep concentration.
Filter Reset Indicator
As for the Filter Reset Indicator, having it is a must. With this option, you are free from the need for constant monitoring of how used-up the filter of your air purifier is. Both LV-H134 and Core 400S have this feature, located next to the control table. The only difference, if I may call it that way, is that Levoit Core 400S can monitor this feature through the Smart app.
Smart App (VeSync)
Between these two Levoit air purifiers, only Core 400S can connect to the VeSync app. You can install the app regardless if you have an Android or iOS cell phone. Like many other gadget apps, it provides a whole new set of additional options for Core 400S.
Timer
One of those common features is the Timer, which allows you to set the time range for an air purifier. You can set it running between 1-12h. Once the time runs out, the Timer will let you know, and the appliance will turn OFF. An extra detail to the Core 400S is that you can control all the Timer settings across the VeSync app.
As for the Levoit LV-H134, everything is the same except the App, because that type of connectivity is not available in this case.
Lock Screen
Only Levoit Core 400S comes with this feature, and it is quite handy I must admit. Even more so if you have a child or a curious pet that likes to press buttons for no reason. All you have to do is to hold the button for 3 seconds, and the device is locked. The same goes for the unlock procedure. The great thing is that you can still control the device via the VeSync App, even when it’s locked.
Screen Off
Opposed to the Lock screen option, Levoit also has a Screen Off option. This feature lets you adapt the device to a current situation. For example, by turning this option ON, you can dim all the lights to make your device practically invisible during the nighttime. But let me tell you a secret. You can obtain the same result by switching the device to Sleep Mode.
Display Off
The Levoit LV-H134 and Levoit Core 400S have this feature, which is available directly on the control panel. This is quite a handy option, allowing you to turn OFF all the indicators that this device owns. So, if you want your air purifier to be invisible during the nighttime and Casper-like-invisible, during the day, you can use this option.
Airflow
Being cylindrical as it is, Levoit Core 400S also has the same shaped filter within. Air inlets are located all around the device’s bottom part. Once the air is filtered, it gets released through the upperside grilles. Even though Levoit LV-H134 does not have sharp edges, we cannot say it is entirely cylindrical. However, the airflow is the same as that of the opponent, since the air inlets and grilles are positioned on identical parts of devices.
Warranty
Since both air purifiers are products of the same company, it is to be expected that they share the same warranty option. Levoit gives a 2-year warranty for all of its products, as long as you register on its website right after the purchase. Trust me, even though this sounds like a condition sine qua non, Levoit gives so much more in return.
Filtration Technology
If you were expecting some mind-blowing filters in any of these air purifiers, you might end up disappointed. Don’t be. These two devices have a perfect 3-in-1 combo that never fails. Of course, I am talking about the Pre-filter, True HEPA filter, and an Activated carbon filter.
Pre-filter in both Levoit Core 400S and Levoit LV-H134 is kind of the first line of defense. It prevents all the large particles like dust, pet hair, fiber, etc., from penetrating, hence, protecting the True HEPA filter.
The True HEPA filter is the second filter in line, designed to capture at least 99.97% of airborne particles, such as smoke, allergens, and fine dust. By catching PM2.5 particles it protects you from all the potential yet invisible threats to your respiratory system.
The last in line is the Activated Carbon filter, pellet based, that keeps your room free from unpleasant odors, smoke, and fumes. Levoit Core 400S even has a specially designed ARC formula that keeps away cooking and pet odors.
One thing you need to keep in mind is that none of these filters is washable. So, if you want them to last long, you must keep that in mind and wipe or vacuum them every once in a while.
How to Replace Filters on Both of These Devices?
Washing filters in either Levoit LV-H134 or Levoit Core 400S is a big NO. Therefore, if you keep them clean, they can last pretty long. However, there will come a time when replacing the filters will be on your To-do list.
As I said earlier, you will have a little helper on your way with the Filter Reset Indicator. All you have to do is to pay attention to the little light on the control panel.
Levoit LV-H134 filters will last long, approximately 6-8 months, but Levoit 400S can beat that with a once-a-year replacement rate.
Nevertheless, replacing any of the mentioned filters shouldn’t take much of your time and effort, so don’t be lazy. You know it’s worth it.
