Clearing the Air: Inside the Market of the Levoit Core 300 Series

Written By: Dr Fahad Yasin

BASIC PURIFIER, GREAT PERFORMANCE

The Levoit Core 300 air purifier is a basic air purifier with 3 fan speeds, a timer, and a sleep mode. It can treat rooms up to 215 sf. in size and had strong performance in our at-home tests. The 300S steps it up with air quality sensors and app connectivity.

Pros

  • Good for small areas, maxing out coverage around 215 square feet.
  • Lightweight and easy to move to various locations
  • 360° HEPA filtration
  • Auto Mode and real-time air quality monitoring (Core 300S only)

Cons

  • No auto mode with the standard Core 300
  • No LED light to display current air quality with the standard Core 300

Purification Test

Picture this: a medium-sized room, the Levoit Core 300 humming away, and a timer set for an hour. I could almost visualize the particles being sucked away, the graphs in my mind showing a downward trend of pollutants. The baseline and post-run data were as contrasting as a bull and bear market.

We used the Temtop LKC-1000S+ professional air quality detector to get a baseline reading for the existing air quality.

From there, we let the purifier run for an hour and then re-ran measurements.

The difference between the baseline and post-run data gives a solid picture of how well the air purifier was able to improve indoor air quality.

Within 1 hour the Levoit Core 300 removed 96% of air particulates from the medium-sized room we tested in (~12’x12′).

The Core 300S removed 94% of air particulates from a medium-sized room we tested in (~14’x10′).

The Core 300 improved PM2.5 air quality by 87% while the 300S improved PM2.5 air quality by 97.3%. Overall, the Core 300 and 300S air purifiers did an exceptional job of purifying the air.

Below, we’ve included information on the testing criteria and what defines good vs. bad air quality.

The Filters

This Levoit Core 300 and 300S uses a trio of filters including:

  1. Fine pre-filter: captures larger particles like dust, lint, or fibers
  2. HEPA filter: captures particles as small as 0.3 microns
  3. Activated carbon filter: for odors like smoke, food, or pets

When it’s time to replace the filters, a filter indicator light on top will glow to let you know.

Noise Test

The Core 300S was tested from about 3’ away.

Our results showed the following decibel levels from each mode.
Sleep

17.5 dB

Low

22.0 dB

Normal

29.1 dB

41.6 dB

45.0 dB

According to the manufacturer, the Levoit Core 300 has a range of 17.5-45 db.

So even on the highest modes the Core 300 / 300s is still extremely quiet.

    Maintenance

    Like any prized asset, it needs its check-ups, its moments of introspection to ensure it remains in top form.

      1. Wipe down the air intake and outlet grills with a dry, lint-free cloth
      2. Replace the filters every 6-8 months as recommended by the manufacturer
    Because the Core 300S has app connectivity, it will also notify you via the app if the filter needs to be replaced.
