Purification Level and Type of Filter

The LEVOIT Core 300 features a 3-stage filtration system that helps to rid your home off VOCs, dust, mold spores, bad odor, smoke, and airborne bacteria. During our testing, we realized that each stage on the filtration system removes specific pollutants, as explained below:


This stage captures large air pollutants like lint, fibers, pet dander, and hair

True HEPA Filter

This filter traps 99.97% of micro allergens like pollen, virus, and bacteria particulates measuring as small as 0.3 microns

Activated Carbon Filter

This filtration stage ensures that no smoke or odors of any kind are left lingering in your indoor air.

The LEVOIT Core 300 air purifier also features an airtight seal to ensure that all the trapped contaminants remain inside the filter.

Tip: We observed that the unit’s performance dwindles when the pre-filter becomes clogged; therefore, we recommend that you keep an eye and vacuum it every two weeks.

Furthermore, LEVOIT sells 3 different types of filter to better suite your needs. You have following 3 options.

  1. Original Filter, Core 300-RF: This is an excellent multipurpose filter
  2. Pet Allergy Filter, Core 300-RF-PA: This is for animal lover and anyone with pet allergies
  3. Toxic Absorber Filter,  Core 300-RF-TX: This is a perfect choice for high level smoke, smog and VOCs

Coverage and Performance

The LEVOIT Core 300 boasts a 360-degree air intake grill, which goes a long way in ensuring that air is drawn evenly from all the corners of your home.

This unit uses Vortexair Technology that creates a powerful airflow, which allows it to cover extensive areas measuring up to 219 sq. ft.

What captured our attention about this unit’s performance is its ability to work with minimal noise output, merely 24 dB. With such calmness, you can sleep or work comfortably while the unit is running without any disruption.

This unit is also Energy Star rated for low consumption of electricity.


With a top-mounted touch control panel, the LEVOIT Core 300 offers quick and direct access to its buttons. The control panel is well-labeled with images and thus allowing you to operate the unit with remarkable ease.

Besides, all the buttons light up when you touch them, which means that you can operate the unit in pitch darkness without much struggle.

For added convenience, this unit comes with the following:

Three fan speeds: Come in handy when selecting your ideal rate of air purification

Timer: Allows you to set the unit to operate for 2/4/6/8 hours before stopping

Special Features

At this point, we already think that the LEVOIT Core 300 is a superb air purifier. However, it surprises us with even better features:

Display Lock: This feature prevents kids from messing with your configurations

Sleep Mode: Allows the unit to switch to night mode with reduced fan speed and lighting, reducing interruptions during your sleep

Replacement Filters: This unit allows you to choose between four types of filters depending on the type of pollutant you need to eliminate from your space. These include Original Filter, Pet Allergy Filter, Toxin Absorber Filter, as well as Mold and Bacteria Filter.

Storage and Footprint

The LEVOIT Core 300 is a compact unit measuring 8.70 x 8.70 x 14.20 inches. We, therefore, recommend it for homes with limited space.

Cleaning and Maintenance

The only part that calls for cleaning on the LEVOIT Core 300 is the nylon pre-filter; vacuum this after 2 to 4 weeks of use. You may also vacuum the grille to keep it free of dust and debris, keeping the unit’s airway open.

Based on usages, it is recommended to replace the filter every 6 to 8 months.
