An Insight Into the Shared Features

Before I dive into what makes them different, let’s look at some of the features they have in common.

Here is a list of a few of them.

levoit 400s vs 600s An Insight Into the Shared Features

1. Filtration Systems:

Both cleaners use a three-step process for filtering air. This enables them to get rid of 99.97% of the airborne pollutants in your room. From pet dander to cooking smells, from dust, VOCs to bacteria. These filters do it all!

The following are the three types of filters used in these models.

levoit 400s vs 600s filters

1. Pre Filter

It works as a primary filter to capture large airborne particles such as:

  • Hair
  • Lint
  • Dust
  • Pet Fur

It also helps to prevent the HVAC system from clogging while they are running. This way, it prolongs the air filter’s life.

2. A True HEPA Filter

This is very effective in removing most of the air particles’ impurities. They remove;

  • Pollens,
  • Germs,
  • Bacteria,
  • Viruses,
  • Spores,
  • Dust,
  • Smaller airborne pollutants.

These filters help capture particles that are smaller and get through the initial primary filter to help reduce respiratory infections and asthma symptoms.

3. Activated Carbon Filter

The filter containing activated charcoal is the third sieve to absorb.

  • Smoke,
  • Cigarette smell,
  • Cooking odor,

  • The PM 2.5 value shows the number of particles detected by the device.

levoit 400s vs 600s What Features Set Them Apart

1. Physical Attributes:

This is the first difference you’ll notice between the two air purifiers. The 400S has a more cylindrical shape, round corners, smaller in size.

2. Room coverage:

While both are great options to suit your needs. The Core 600S can cover an area of up to 635 square feet while the 400S covers around 403 square feet in a room.

This means the 600S can clean much large room spaces such as living rooms, kitchens, open spaces, etc., while the Core 400S is ideal for smaller spaces such as bedrooms, offices, studios, etc.

Winner: The 600S has better and bigger area coverage, thus taking the lead in this domain.

3. CADR Rating

This is how the CADR differs in both.

  • The CADR for 400S is 260 CFM.
  • The CADR for Levoit Core 600S is 410 CFM.

This translates into a 600s air purifier cleaning more air than the 400 on the same settings.

Winner: The Levoit Core 400S is a good option for anyone looking for a simple and efficient air purifier, but the 600S offers even better performance by taking the lead.

4. Pricing

Here is how they compare regarding the purchasing cost:

  • The 400S cost around 219 dollars
  • While the Levoit Core 600S retails at $299.

Winner: When it comes to pricing, the winner is 400S making it a budget-friendly option.

5. Filter Replacement Cost

The cost of filter replacement for each of the air purifiers is as follows.

  • The Levoit 400s: The cost is around $50 per filter.
  • The Levoit Core 600s: This cost $60 per filter.

Winner: The devices use the same filter; the only difference is the size. Since the 600S provides a bigger filter size, it is more expensive than the other. Thus, the 400S is a more cost-effective option.

6. Energy Consumption

The Levoit Core 400S and the Levoit Core 600S differ in power usage. The Core 600S has a higher power consumption.

  • The 600S consumes around 49W at its highest fan setting.
  • The 400S on the other side, uses less energy of 38 W.

Winner: The 400S air purifier uses less energy. Thus, regarding power consumption, the 400 takes the lead. But do remember, the 400S delivers lesser coverage and airflow than the Levoit Core 600s.

You can look at how they compare with each other in this video.

7. Noise Level

This is how the two models compare in noise;

  • At the lowest setting, the 400S makes a sound of 42 dBA
  • While the 600S of 43.9 dBA.

Now this isn’t that much of a difference. But how do they compare with the highest fan speed turned on?

  • 59 dBA for the 400S model and
  • 68.5 dBA for Levoit core 600S

Winner: The 400S model is much quieter when it operates at the highest setting. Thus making it the winner in this regard.
