Some Levoit air purifiers use filters described as HEPA-grade, while others claim 99.97% particle capture at 0.3 microns. “True HEPA” isn't a safe label to assume across the whole brand, so check the exact model and filter wording.

The Core 300-P is described as HEPA-grade while operating in Sleep Mode. The Core 400S-P is described as capturing 99.97% of airborne particles down to 0.3 microns, but that wording alone doesn't call it a “True HEPA” filter.

Is a Levoit air purifier true HEPA?

The answer depends on the model and how its filter is described. Levoit calls the Core 300-P Original Filter HEPA-grade in Sleep Mode, while the Core 400S-P filter claims 99.97% capture at 0.3 microns.

Those descriptions provide useful clues, but they aren't interchangeable. Check the model number, the operating mode tied to any HEPA-grade wording, and the filter's stated particle-capture performance before choosing a purifier.

For a broader explanation of the terminology, see What Is the Difference Between HEPA and True HEPA Filters?. The term HEPA also appears in vacuum discussions, but a HEPA filter in a vacuum belongs to a different appliance context.

What does HEPA-grade mean on the Core 300-P?

The Core 300-P Original Filter is described as HEPA-grade while the purifier operates in Sleep Mode. For operating guidance, see use the Levoit Core 300.

Levoit ties that statement to an independent lab test, so keep the model and mode in view when comparing the claim.

The filter is also described as capturing 99.97% of particles from 0.1 to 0.3 microns. That range is a separate performance detail; it doesn't make every Levoit model or replacement filter equivalent.

Does the Core 400S-P use a True HEPA filter?

The Core 400S-P filter is described as capturing 99.97% of airborne particles down to 0.3 microns. Its three-stage system includes a pre-filter, a main filter and an activated carbon filter.

That capture claim can help you compare models, but the wording provided doesn't label the filter “True HEPA.” If that exact label matters to you, verify the current model-specific filter description before buying.

Which Levoit filter parts are washable?

Don't assume a Levoit air purifier filter is washable because the purifier has multiple filter layers. The Core 400S-P has a pre-filter that captures dust, lint, fibers, hair and pet fur, but the stated product details don't say that the pre-filter is washable.

The main particle filter and activated carbon filter also aren't described as washable. Follow the care instructions for your exact model, and don't rinse or soak any filter unless those instructions explicitly allow it.

A washable pre-filter, when a model's instructions confirm it, is different from a washable main filter. Compare reusable and filterless air purifiers if you want to explore other filter designs.

A filter can trap larger debris on its outer surface while still needing replacement rather than washing.

Which model details should you compare?

Match the filter claim to the exact model number first. Then compare the stated particle size, capture percentage, room coverage and any operating mode attached to the claim.

ModelFilter details to checkOther useful detail
Core 300-PHEPA-grade in Sleep Mode; 99.97% capture for 0.1 to 0.3 micron particlesReplace filter every 6 to 8 months, per Levoit
Core 400S-P99.97% capture down to 0.3 microns; three-stage filtrationPre-filter, main filter and activated carbon filter

A room coverage number doesn't tell you whether a filter is True HEPA. Treat room size and filter wording as separate questions: choose coverage for your space, then verify the model's filtration details.

What does a capture percentage tell you?

A capture percentage describes how much of a stated particle size range a filter is claimed to capture. Read it with the particle size, model and any testing or operating conditions given alongside it.

For example, 99.97% down to 0.3 microns is a specific claim, but it doesn't identify every material in the filter or prove that another model has the same performance. Don't transfer one model's claim to a different purifier.

Which Levoit purifier fits your filtration needs?

Choose based on model-specific filter wording, room needs and the features you want. For a model-to-model comparison, see Coway Airmega Mighty vs Mighty 2.

These three models have different stated filtration details, so compare each one against the wording you need.

Is the Core 400S-P right for a large room?

The Core 400S-P is described for rooms up to 1,718 square feet with one air refresh per hour. Its three-stage filter captures 99.97% of particles down to 0.3 microns, and its activated carbon layer adsorbs smoke and odors.

Choose it if you want app controls, an air quality sensor and automatic fan adjustment. The product details call its main layer a filter, not a True HEPA filter, so verify the current model wording if that label is essential.

Is the Core 300-P a good fit for pet hair and dander?

The Core 300-P uses a three-stage Original Filter and is described as HEPA-grade in Sleep Mode. Its stated filtration covers pollen, dust and animal dander, while the pre-filter captures larger debris such as hair.

Choose it if you want a model with a specific HEPA-grade statement and a filter replacement interval of 6 to 8 months. Its stated coverage and filter claims apply to the Core 300-P, not every Levoit purifier.

Is the Core Mini-P enough for a bedroom?

The Core Mini-P is described as a small purifier for spaces such as a bedroom, kitchen or office. Its pre-filter and main filter capture lint, hair, pet dander and fine airborne pollutants.

The supplied model details don't give a HEPA-grade or True HEPA claim for this purifier. Choose it for its small size and stated use areas only after checking whether its current filter description meets your needs.

See the best Levoit air purifiers for more model comparisons, or Levoit air purifiers for bedrooms if nighttime placement is your main concern. For setup and controls, use the guide to how to use a Levoit air purifier.

Can you wash a Levoit filter to save money?

Only wash a filter if your model's care instructions clearly say that specific filter part is washable. Washing a main filter that isn't designed for it can damage the filter and affect how it works.

A “Levoit air purifier washable filter” search may lead to different models or replacement parts. Confirm the exact model and part number before assuming a washable filter fits your purifier.

The Core 400S-P details identify a pre-filter, main filter and activated carbon filter, but don't state that any of those parts are washable. Check the manual for care steps and replacement timing, especially if your room has pets, smoke or frequent dust.

Does every Levoit purifier use the same filter?

No, filter design and claim wording vary by model. The Core 300-P, Core 400S-P and Core Mini-P have different stated filter descriptions, so a “Levoit true HEPA air purifier” search should lead you to verify the exact product.

A replacement filter must also match the purifier model. Don't choose one by brand name alone, since the model's fit and filtration details matter; the Levoit replacement filter guide can help narrow the match.

An air purifier also doesn't add moisture to a room just because it moves air. For a purifier with a humidifier, see the Levoit purifier and humidifier combo.

If you're comparing that function, see whether a Blueair air purifier and humidifier can serve both roles.

How should you decide if a Levoit model meets your needs?

Pick the Core 300-P if its HEPA-grade-in-Sleep-Mode wording fits your criteria, and pick the Core 400S-P if you want its stated 99.97% capture claim and large-room coverage. Consider the Core Mini-P for a smaller space, but verify its filter wording if HEPA classification is important.

For any Levoit air purifier, compare the exact model number, filter claim, washable-part instructions and replacement filter fit. If “True HEPA” is a requirement, rely on the current model-specific wording rather than a general brand search result.

Frequently asked questions

Is a Levoit air purifier true HEPA?

It depends on the model and filter. The Core 300-P is described as HEPA-grade while operating in Sleep Mode, and the Core 400S-P filter is described as capturing 99.97% of particles down to 0.3 microns.

Check the exact model's current filter description instead of assuming every Levoit purifier uses the same filter.

Can you wash a Levoit air purifier filter?

Don't wash the main filter unless the instructions for your exact model say it is washable. The Core 400S-P has a pre-filter that captures larger debris, but that doesn't mean its main particle filter or activated carbon layer can be washed.

Follow the care instructions for the filter you own.

What does HEPA-grade mean on a Levoit purifier?

For the Core 300-P, Levoit describes its Original Filter as HEPA-grade while the purifier runs in Sleep Mode, based on an independent lab test. That wording is specific to the model and operating mode.

It isn't a reason to assume every Levoit filter has the same classification.

How often should I replace a Levoit air purifier filter?

Replacement timing depends on the model, filter and use. For the Core 300-P, Levoit recommends replacing the filter every 6 to 8 months.

Check the instructions for your model and use its filter indicator if it has one; the interval can vary with air conditions and operation.
