Step by Step Cleaning Levoit Air Purifier Filter

  1. Understanding the Importance of Cleaning the Filter

    Before diving into the cleaning process, it’s essential to understand why it’s crucial. Filters trap a variety of pollutants, ranging from dust and pollen to smoke and pet dander. Over time, these particles accumulate, reducing the filter’s efficiency and the air purifier’s overall effectiveness. This can also strain the device, leading to higher power consumption and a shorter lifespan. Hence, understanding how to clean Levoit air purifier filter becomes a key aspect of ensuring longevity and optimal functioning of your air purifier.

  2. Gathering the Necessary Supplies

    Before you begin the cleaning process, ensure you have the following items handy:
    – A soft-bristle brush
    – A clean, dry cloth
    – Vacuum (with a brush attachment)
    – A gentle cleaning solution (for stubborn stains)

  3. Safety First: Turn Off and Unplug Levoit Air Purifier

    Safety should always be a priority. Before attempting to clean or even touch the filter, ensure the air purifier is turned off. After turning it off, unplug it from the wall socket to eliminate any risk of electrical shocks.

  4. Accessing the Levoit Filter

    Place your Levoit air purifier on a flat surface.
    Locate the filter compartment. It’s typically at the back or bottom of the device.
    Open the compartment cover. Most Levoit models have a simple latch or clip system that allows easy access to the filters.

  5. Inspecting the Filter

    Before you dive into how to clean Levoit air purifier filter, do a thorough visual inspection. This will give you an idea of the filter’s condition and help you decide whether it just needs cleaning or a full replacement.

  6. Begin Cleaning the Pre-Filter

    The pre-filter is the first line of defense and catches larger particles like hair and dust.

    – Gently tap it to dislodge any loose debris.
    – Use a soft brush or the brush attachment of your vacuum to gently sweep away accumulated particles.
    – For stubborn dirt or stains, dampen your cloth with a gentle cleaning solution and wipe the pre-filter. Ensure the filter is completely dry before reinserting it.

  7. Cleaning the True HEPA and Activated Carbon Filters

    It’s vital to note that the HEPA and activated carbon filters should not be washed with water. Using water can damage the intricate fiber structures, rendering the filter useless.

    – Gently vacuum the surface of the HEPA filter to remove fine particles. Make sure to use a gentle setting to prevent damage.
    – For the activated carbon filter, simply vacuuming should suffice. If there are noticeable odors emanating from the filter, it’s a sign that it might be time for a replacement.

  8. Reassembling the Air Purifier

    After ensuring all filters are clean and entirely dry, it’s time to put everything back together.

    – Place the filters back in the correct order: pre-filter first, followed by the HEPA filter, and then the activated carbon filter.
    – Once all the filters are securely in place, reattach the compartment cover.
    – Plug the air purifier back in, turn it on, and enjoy the fresh air.

  9. Regular Maintenance is Key

    While knowing how to clean Levoit air purifier filter is crucial, setting a regular cleaning schedule is equally important. Depending on the air quality in your home and how often you run the purifier, it’s advisable to clean the pre-filter at least once a month and inspect the HEPA and carbon filters during this time.

  10. Know When to Replace

    Cleaning can extend the life of your filters, but it’s essential to recognize when they need replacing. Typically, HEPA filters have a lifespan of 6-12 months, while activated carbon filters last around 3-6 months. Always refer to your Levoit air purifier’s manual for specific guidelines on filter replacement.

Signs That Your Filter Needs Replacement

Here are some signs that indicate your air purifier filter needs replacement:

  1. Reduced Efficiency: If you notice that the air purifier is taking longer than usual to purify the air in a room, it might be due to a clogged filter. As the filter captures more and more particles, its efficiency can decrease.
  2. Persistent Unpleasant Odors: If you start smelling odors that your purifier previously eliminated (like pet odors or smoke), this could be a sign that the activated carbon filter is saturated and needs replacing.
  3. Increased Allergy Symptoms: A significant increase in allergy symptoms, such as sneezing, runny nose, or itchy eyes, can be a sign that your filter is no longer trapping allergens efficiently.
  4. Visible Dust and Dirt: If you can see a buildup of dust and dirt on the filter surface, it’s a clear indication that it’s time for a replacement.
  5. Increased Noise Level: An unusual or loud noise coming from the air purifier can be an indication that the filter is clogged, making the machine work harder.
  6. Filter Replacement Indicator: Many modern air purifiers come with a filter replacement indicator light that will alert you when the filter needs changing.
  7. Check the Filter’s Color: Over time, white HEPA filters will turn gray or black when they’re filled with particles. If the color change is uniform across the filter, it’s time for a replacement.
  8. Consistent Drop in Airflow: If you feel less airflow coming out of the purifier, it might be because the filter is clogged.
  9. Extended Usage: Even if you don’t observe visible signs, if you’ve been using the filter for longer than the manufacturer’s recommended period, it’s a good idea to replace it.
  10. Physical Damage: Any visible signs of wear, tear, or damage to the filter, like holes or rips, mean it should be replaced immediately to maintain air purifier efficiency.
  11. Humidity or Wetness: If for any reason your filter becomes wet (maybe due to spills or high humidity), it’s crucial to replace it. A wet filter can become a breeding ground for mold and bacteria.

Always keep in mind that regular filter replacement not only ensures that the air purifier works at its optimum efficiency but also ensures that the air you breathe is clean and healthy.

Different Types of Filters in Levoit Air Purifiers

Levoit air purifiers are renowned for their effectiveness and efficiency in purifying indoor air. A significant part of their effectiveness is due to the types of filters they utilize. Here are the different types of filters commonly found in Levoit air purifiers:


  • Purpose: This is the initial stage of filtration in most Levoit air purifiers. It is designed to capture large particles such as pet fur, hair, and lint.
  • Maintenance: The pre-filter can often be cleaned by vacuuming, ensuring its efficiency remains optimal.

True HEPA (High Efficiency Particulate Air) Filter:

  • Purpose: A True HEPA filter is designed to capture up to 99.97% of particulate matter as small as 0.3 microns. This includes allergens like pollen, dust mites, and pet dander.
  • Maintenance: HEPA filters are usually not washable. They should be replaced when they become dirty, roughly every 6-12 months depending on the air quality and usage.

Activated Carbon Filter:

  • Purpose: This filter type is primarily for removing odors and harmful gases from the air. It’s especially useful for households with smokers, pets, or nearby sources of outdoor pollution. The activated carbon attracts and captures these odors and gases.
  • Maintenance: Like the HEPA filter, activated carbon filters are typically not designed to be washed. They need replacement when they become saturated, which can range from a few months to a year, depending on the conditions of use.

Vital Ion:

  • Purpose: Some Levoit air purifiers come with an ionizer, which releases negative ions. These negative ions bond with positive ions (like dust or allergens) in the air, making them heavier and easier for the filters to capture.
  • Maintenance: Ionizers usually don’t require maintenance, but they can often be turned on or off based on user preference.

UV-C Light (in some models):

  • Purpose: UV-C light helps in killing bacteria, viruses, and germs. It adds an additional layer of air purification by targeting microorganisms.
  • Maintenance: The UV-C bulb might need replacement after a specific period, typically every 1-2 years.

Antimicrobial/Anti-Virus Filters (specific to certain models):

  • Purpose: These filters are treated with agents that effectively neutralize or kill certain microbes or viruses, ensuring even finer protection against pathogens.
  • Maintenance: These filters, like HEPA and activated carbon filters, are replaced periodically based on usage and air quality conditions.

When considering a Levoit air purifier, it’s essential to understand the types of filters included in the specific model and their purposes. This will allow you to choose a model that best suits your needs, whether that’s allergen removal, odor neutralization, or pathogen protection. Regular maintenance and timely replacement of filters ensure that the purifier functions at its best, providing you with clean and healthy air.
