A filter indicator will light up to remind you to check your air filter.

Depending on how often you use your purifier, the filter indicator should turn on at 6-8 months (except for the 400S, 600S and mini). It is not essential to replace your filter when the filter indicator lights up, but you must check your filter to see if it needs replacing – this is also why the filter life is usually a range and not a hard number.

1-Cleaning the outer side

  • Unplug your Air Purifier before cleaning.
  • Wipe the outer side of your air purifier using a damp cloth, and then immediately dry it. Don’t use any abrasive chemicals or flammable cleaning agents.

2-Cleaning the inner side

  • For cleaning the inner side of the air purifier, use a vacuum cleaner. To increase the efficiency and life of the filter, it is best to clean the outer pre-filter every two to four weeks.
  • Use a vacuum hose or a soft brush to remove dust, hair, or other entrapped large particles in the pre-filter. Don’t use water or any other liquid to clean the air filter.

3-Cleaning the Air quality sensor

Dust can accumulate in the air quality sensor, and it can stop working correctly. So, it’s usually best if you clean it regularly.

For cleaning the air quality sensor:

  • Open the sensor cover to access the air quality sensor.
  • Clean the sensor lens using a damp cotton swab.
  • Then dry the sensor lens using a dry cotton swab.
  • Once you’re done, close the sensor cover.

4-Cleaning the Pre-Filter

To clean the Pre-Filter use a soft brush or vacuum hose. Take extra care to remove any dust or hair.

  • Do not clean the Pre-Filter with water or soap.
  • Clean the Pre-Filter every 2-4 weeks.

Why Do You Need A Levoit Core air Purifier?

According to the Environmental Protection Agency, in 2020, about 68 million tons of contaminants were emitted into the atmosphere in the United States. Emission of these air contaminants contributes to acid deposition, formation of ozone particles, and visibility impairment.

Americans spend 90% of their time indoors where pollutants concentration is 2-5 times higher than outdoor pollutants’ concentration. Levoit has come up with innovative air purifiers to clean your indoor atmosphere, making it fresh and suitable for breathing.

Gases from tobacco smoke, cleaning products, building materials, dust, and mold significantly contribute to polluting indoor environments.

Small particles, particularly those with a size of around 10 micrometers, are primarily a concern, as they can penetrate the lungs causing asthma attacks, allergic reactions, and various heart-related diseases.
Therefore, Levoit Core air purifiers need regular cleaning to keep providing you with clean and contaminant-free air.
