Levoit Core 400s vs 300, Complete Comparison

For those looking for an air purifier that doesn’t break the bank, Levoit Air offers a range of models at affordable prices. The company’s Core 300 and 400S units are both efficient at removing particles from your indoor spaces. While, maintaining good airflow to ensure freshness in every room—and can be used year-round without issue!

Levoit has been designing innovative products for many years when they first introduced their very popular line up of desktop ventilation fans specifically designed so people living alone wouldn’t have themselves overheating during the winters.

A review is always incomplete without a side-by-side comparison of specifications, so I’ll begin with an evaluation of Levoit core 400s and 300. The majority will be devoting to comparing features that each product has to offer as well as analyzing these specific details for both devices! That’s why we’re here to explain the differences between the Levoit Core 400s vs Core 300.

Levoit Core 400s vs 300 Comparison:

The Levoit Core 400S is a new, highly-efficient smart air purifier with performance rivaling that of its most popular model, the LVH133 (260 cfm vs 274).

It also offers app control which allows you to set up schedules for when it will clean. And how powerful your desired filters should be in order to get rid of various allergens like dust mite allergy or pet dander, respectively, among other things – all via an easy user interface on your phone!

Levoit Core 300 is a high-end air purifier with an affordable price tag. At 360 degrees, this quiet machine can cleanse your room five times per hour and emit no ozone! The Smoke CADR rating of 141 CFM removes 210 sq ft worth of bacteria in just one go making it perfect for smaller living spaces such as bedrooms or offices.

Where you need stronger cleaning power without having to worry about loud noises disturbing people nearby. Here is a more detailed side-by-side comparison between levoit core 400s and core 300 so you can make an informed decision.

Levoit Core 400s vs 300 Performance:

The Core 400S Smart True HEPA Air Purifier, which is somewhat larger than the Core 300, has the same lovely finish as the Core 300 but covers a greater area. The jury praised the air purifier’s QuietKEAP technology, which maintains noise levels below 24dB.

These advanced capabilities combine with Smart Control to create a user-friendly experience that distinguishes the Core 400S from its competitors.

Levoit Core 400s vs 300 Filtration System

Both the levoit core 400sand the levoit core 300 include a 3-stage filtering system

Users praise the Levoit Core 400S for its strong filtration performance in addition to its smart features. The pre-filter, H13 True HEPA filter, and activated carbon filter are all part of a three-stage composite filtering system.

Their state-of-the-art 3-stage filtration technologies are used in the 400S. The Levoit ARC Formula is used in the new 400S, which is a fancy way of saying it’s a top-of-the-line air purifier. Dust, pollen, pet dander, and smoke particles are easily removing.

Pre-filter removes larger particles like hair, lint, pet fur, and larger dust particles.

HEPA Filter removes 99.97% of all air pollutants with a diameter of 0.3 microns. Cooking odors, fireplace smoke, and cigarette smoke can all be removing with this method.

The Carbon Filter collects gases like smoke and VOCs (volatile organic compounds), which are typically found in cleaning chemicals.

The Levoit Core 300 includes a 3-in-1 filter cartridge that includes a pre-filter net, a genuine HEPA filter, an activated carbon filter. A net pre-filter is the outermost filter, and it protects the inner filters from becoming clogged. Larger airborne particles, such as lint, dust, and cat fur, are captured.

The attached pre-filter is not washable. Thus Levoit recommends cleaning it every 2 to 4 weeks with a soft brush or a vacuum hose. It will extend the 3-in-1 filter’s life and improve its efficiency.

The core particle filter is a real HEPA filter that captures 99.97% of household dust, dust mites, pollen, mold spores, and smoke particles with a diameter of 0.3 microns.

The third phase of Filtration uses granular activated carbon materials to absorb odors from pets, cooking, and volatile organic compounds (VOCs). However, because the filter bed is thicker, this is not a heavy-duty odor absorber. If removing odors from your room is your top concern, don’t choose it.

Levoit Core 400s vs 300 Noise Level:

Air purifiers by Levoit are among the quietest. None of their units exceeds noise levels of 55 decibels.  In reality, the 400S operates at the lowest speed in any of our bedrooms 99 percent of the time, which I assume means it’s only 24 dB noisy.

To put that in context, 20 dB is the same as whispering. It’s scarcely audible at this point. My daughter and I don’t even notice it running in the middle of the night when we’re asleep.

There are no air quality sensors on the Levoit Core 300. The lowest noise level is only 24 dB, which is barely audible, and the highest noise level is around 50 dB, which is a little more than expected for a 141 cfm air purifier. As a result, you’ll have to use it at night in your small bedroom, although at a lesser fan speed.

Levoit Core 400s vs 300 Room Coverage:

The Levoit core 300 effectively covers up to 710 ft2 / 66 m2, and Auto Mode keeps you informed about the air quality indicator ring and PM2. 5 value. With Levoit’s LV-H133 Tower True HEPA Air Purifier, you can breathe clean air.

The Levoit Core 400S performed admirably in the stress test, cleaning 99.92 percent of all airborne particles down to 0.3 microns in a 200-square-foot room in just one hour.

The Levoit Core 400S is a low-range air purifier that can handle a large space. As you can see, this air purifier’s recommended room coverage is up to 403 square feet, which is sufficient for the living room of many large houses in the United States. Levoit Core 400S has a 5X ACH. Thanks to its revolutionary Vortex Air technology, the air purifier can purify the indicated space up to 5 times per hour.

In general, the CADR of the Levoit Core 400S is 260 cfm. In the low-range market, such strong fan power competes with the best Coway AP-1512HH and Winix AM90.

Levoit Core 400s vs 300 Power Consumption:

The Levoit Core 400S is 38 watts, which is the average of the LV-H133 and LV-H135. Such energy savings are superior to the best competitors, barely falling short of the best Blue Pure 311 Auto by a small margin.

If you already own a Levoit Core 400S, you can be assured that running the air purifier for at least 8 hours each day will cost you only $14.

Levoit Core 300 will be more powerful with the AC capacitor motor, but it will waste more energy than a conventional DC motor. I don’t want to bore you with technical jargon, so all you need to know is that the Levoit Core 300’s rated Power is roughly 45 watts, with a standby power of fewer than 0.8 watts.

It’s fantastic for an air purifier with an Energy Star rating for efficiency. To put it another way, the Levoit Core 300 is still an energy-saving air purifier. You will only have to pay $16 per year if you run this air purifier for 8 hours each day.

Levoit Core 400s Features

Some of the Best Features are Discussed Below

Sleek Design

The Levoit Core 400S is a sleek and modern design. With its cylinder shape, the purifier stands out from other similar models on store shelves or online for that matter!

One of its most notable features is those 360-degree air outlets at the top, which allow you to place this anywhere in your home without worrying about any blockages due directly from where the unit draws unfiltered breathable oxygen into one’s sleeping area while simultaneously removing up dirty particles as well as allergens before they enter through walls so everyone can get their much-needed rest soundly tonight knowing there will be no morning headaches.

Smart Capabilities

Finally, there’s a way to enjoy fresh air without worry! The Smart Capabilities of this award-winning purifier are what make it so great. First off, you can connect its Wi-Fi enabled features and control it remotely with an app (for iOS & Android).

It also works well as part of your home automation system -just like how lights work their magic, or other electronics do up next door in that dead silence before morning time begins anew.

The app not only allows you to check the real-time PM2.5 counts but also provides air quality graphs daily and weekly, which makes it easy for people with respiratory illnesses like COPD or asthma to monitor their condition more closely than ever before without having a session of an expensive medical kit, in addition, looking at charts when they’re feeling better!

Powerful Filtration Performance

The Levoit Core 400S is a high-quality home air purifier. Its 3 stage filtration system, consisting of pre-filter, HEPA filter, and activated carbon, has been proven to capture 99%+ particulate matter from the air before it even enters your lungs!

Two Auto Modes and Laser Dust Sensor

The purifier has a laser-based dust sensor.  In seconds, this innovative technology detects and identifies particles in your indoor air at the back of the unit.  The first blue ring will appear after 5 seconds as it automatically detects all different sizes.

That are flying through our homes or offices, including PM2.5, which can lead to serious health problems like heart disease by lodging themselves deep within one’s lungs over time due to their small size (less than 2 millimetres).

  • Low energy consumption
  • Low noise profile.
  • Moderate CADR ratings

Why chose levoit core 400s? 

The Levoit Core 400S Air Purifier is a fantastic addition to any household. It takes 5 seconds to detect PM2.5 particles. If the air quality is poor, the cleaner will automatically alter the fan speed. The quieter aerodynamic fan blades will purify your indoor air faster at high speeds.

Levoit Core 300 Features

There are many of Levoit core 300 but some of the best discussed below!

3-stage Filtration

With a combined 3-in one filter, the Levoit core 300 is guaranteed not to lose any of your air. The pre-filter net catches larger particles such as lint and pet fur while protecting inner filters from being clogged up with these materials. That can cause problems in asthma sufferers or people living a dusty lifestyle!


The Levoit Core 300 is a great choice for those looking to purify their home. A CADR of 141 cfm can handle smoke particles in small or medium-sized rooms without issue. You will get 5 air exchanges per hour with this unit which means that there should not be an excessive amount of time where you are waiting around because the filters need changing!

The 360-degree airflow design provides excellent circulation between the top and bottom outlets so your room stays fresh at all times – no matter what type of furniture/novelty items might reside within its confines.

Aesthetics & Noise Level

Levoit Core 300 is a stylish and compact air purifier. It’s available in black or white, so you can choose your color to match the decor of any room! The touch control panel on top offers easy-to-use features like 3 fan speeds with 4 different timers – 2hr,4hr, 6hr, 8hrs (or just set it for 8).

Pros of Levoit Core 300 

  • 3-in-1 combo filter with real HEPA as the primary filter.
  • A coating of activated carbon granules.
  • 360-degree air intake that is ozone-free.
  • CADR ratings are moderate.
  • The design is simple and attractive.
  • Available in two colors: black and white.
  • Maintenance is low-cost.
  • Certified by the Energy Star program.

Cons of Levoit Core 300 

  • The pre-filter cannot be washed.
  • Efficacy in removing odors is low.

Why Chose Levoit core 300?

The Levoit Core 300 air purifier is a great, small air purifier that is easy to use and covers a large area. Small to medium-sized rooms can use the purifier to filter particle allergens and light odors. It is ozone-free and safe for both children and pets.

You can select between the black and white versions of the Levoit Core 300 if you want a small room coverage air purifier with a high-efficiency particle filter.


Is it effective in removing cigarette smoke odors?

A True HEPA filter and an activate carbon filter are used in the purifier to remove tiny particles and neutralize light to medium odors. The majority of cigarette smoke is made up of gases (90 percent gases/vapors vs 10% particles). So, don’t select it if you want to get rid of the active cigarette odor.

Can I keep my window open while the air purifier is running?

Close the windows and doors to effectively trap airborne particles and maximize efficiency. Purification will be weakened if the purifier is run with the doors and windows open. It will also take longer for the purifier to clear the air.

 Final Verdict

The Levoit Core 400s vs Core 300 are two different humidifiers. Both offer benefits for consumers, but they have their own unique qualities that make them stand out in a crowded market of competing products.
