How to Replace Levoit Air Purifier Filters: A Complete Guide for Optimal Performance and Cleaner Air​

2025-09-30

If you own a Levoit air purifier, regular filter replacement is non-negotiable to maintain its efficiency, extend its lifespan, and ensure your home’s air remains clean. Over time, filters trap dust, allergens, pet dander, smoke, and other pollutants—eventually becoming clogged and less effective. This guide walks you through why, when, and how to replace Levoit filters, with actionable steps tailored to different models, so you can keep your purifier working at its best.

Why Replacing Levoit Air Purifier Filters Matters More Than You Think

Levoit air purifiers rely on a multi-stage filtration system, typically including a pre-filter, activated carbon filter, and HEPA (or H13 True HEPA) filter. Each layer targets specific pollutants: pre-filters catch large particles like hair and lint; carbon filters neutralize odors and VOCs; HEPA filters capture 99.97% of particles as small as 0.3 microns.

When these filters fill up, several issues arise:

  • ​Reduced purification efficiency: Clogged filters force the purifier to work harder, circulating unclean air instead of trapping pollutants.

  • ​Secondary pollution: Trapped moisture and organic matter in old filters can breed mold or bacteria, releasing them back into the air.

  • ​Higher energy costs: A strained motor uses more electricity to maintain airflow.

  • ​Shortened purifier lifespan: Overworking the fan and motor leads to premature wear and tear.

In short, skipping filter replacements undermines the purifier’s purpose—and could even harm your indoor air quality.

How Do You Know It’s Time to Replace Your Levoit Filter?

Levoit designs its purifiers with user-friendly alerts, but environmental factors (like pet ownership or living in a polluted area) may require adjustments. Here’s how to tell when it’s time:

1. Follow the Manufacturer’s Replacement Schedule

Levoit recommends replacing filters every 6–12 months, depending on usage and air quality. For example:

  • ​Standard use (moderate pollution, no pets)​: Every 12 months.

  • ​Heavy use (smoke, pets, or poor outdoor air)​: Every 6 months.

    Check your purifier’s manual for model-specific guidance—some newer models (like the Levoit Core 600S) use smart sensors to adjust reminders.

2. Watch for Visual or Sensory Cues

Even with a schedule, pay attention to these signs:

  • ​The filter indicator light turns red/orange: Most Levoit models (e.g., LV-PUR131, LV-H134) have a color-coded light. Red means “replace now”; yellow may mean “pre-filter needs cleaning.”

  • ​Increased dust or odors: If you notice more dust on surfaces or lingering smells (pet, cooking, or chemical), the carbon filter is likely saturated.

  • ​Reduced airflow: A noisy, strained fan or weak suction indicates the HEPA filter is clogged.

3. Inspect the Filter Directly

Turn off and unplug the purifier. Open the filter compartment and remove the old filter. Hold it up to a light:

  • ​Pre-filter: If it’s dark with hair, lint, or debris, wash it (if reusable) or replace it (if disposable).

  • ​Carbon/HEPA combo filter: If it’s gray or black and feels stiff, it’s time to replace the entire unit.

Step-by-Step: How to Replace Levoit Air Purifier Filters

Replacing a Levoit filter is straightforward, but details vary by model. Below are instructions for common Levoit series:

​Tools You’ll Need​

  • New Levoit replacement filter (match the model number—see below for compatibility tips).

  • Soft, dry cloth (to wipe the compartment).

  • Screwdriver (rarely needed; most models use snap-on compartments).

​Model 1: Levoit Classic Series (e.g., LV-PUR131, LV-H132)​​

These compact purifiers are popular for bedrooms. Here’s how to replace their filters:

  1. ​Power down and unplug: Safety first—always disconnect the purifier.

  2. ​Open the filter cover: Gently press the tab on the front panel and lift it upward.

  3. ​Remove the old filter: Slide the filter assembly out. It may be a single unit (pre-filter + carbon + HEPA) or separate layers.

  4. ​Prepare the new filter: Remove any packaging plastic. If your model uses a pre-filter, separate it from the carbon/HEPA layers (some pre-filters are washable).

  5. ​Insert the new filter: Align the tabs on the filter with the grooves in the purifier. Push until it clicks into place.

  6. ​Close the cover: Snap the front panel back into position.

  7. ​Reset the indicator light: Press and hold the “Filter Reset” button for 3–5 seconds until the light turns green.

​Model 2: Levoit Core Series (e.g., Core 300, Core 400S, Core 600S)​​

The Core series features a modern design and smart sensors. Replacement steps:

  1. ​Power off and unplug: Ensure the purifier is off.

  2. ​Open the top cover: Lift the handle on the top panel; it will pivot backward.

  3. ​Remove the filter cage: Twist the cage counterclockwise to unlock it, then pull it straight down.

  4. ​Take out the old filter: Slide the filter pack (pre-filter + carbon + HEPA) out of the cage.

  5. ​Install the new filter: Insert the new filter pack into the cage, ensuring it sits flush. Twist the cage clockwise to lock it.

  6. ​Place the cage back: Align the tabs on the cage with the purifier’s slots and push upward until it clicks.

  7. ​Reset the sensor: Use the Levoit app (for smart models) or press the “Reset” button on the purifier to clear the filter reminder.

​Model 3: Levoit Vital Series (e.g., LV-H126, LV-H133)​​

These slim, vertical purifiers are ideal for small spaces. Here’s how to swap filters:

  1. ​Unplug and power down: Avoid electric shock.

  2. ​Slide open the front panel: Grasp the edges of the panel and pull it forward.

  3. ​Release the filter clamp: Push the tab on the side of the filter compartment to release the lock.

  4. ​Pull out the old filter: Gently tug the filter assembly out of the purifier.

  5. ​Insert the new filter: Align the filter’s notches with the compartment’s guides and push until it’s secure.

  6. ​Close the front panel: Slide it back until it latches.

  7. ​Reset the indicator: Press the “Filter” button once to turn off the alert.

Common Mistakes to Avoid When Replacing Levoit Filters

Even experienced users make errors—here’s what to watch for:

  • ​Using non-Levoit filters: Third-party filters may not fit, leading to poor sealing (allowing pollutants to bypass the filter) or damage the purifier’s fan. Levoit’s OEM filters are designed to match airflow and dimensions exactly.

  • ​Skipping pre-filter maintenance: Reusable pre-filters (found in some models) need washing every 2–4 weeks. Letting them get clogged strains the main filter.

  • ​Forgetting to reset the indicator: The purifier won’t know you’ve replaced the filter, so it will keep showing the “replace” alert.

  • ​Rushing installation: Misaligned filters can cause rattling noises or reduce airflow. Take time to ensure the filter sits flush.

Where to Buy Genuine Levoit Replacement Filters

To avoid counterfeit products, purchase filters directly from:

  • ​Levoit’s official website: Offers model-specific filters and occasional discounts.

  • ​Amazon, Walmart, or Best Buy: Check the seller’s ratings—only buy “Ships from and Sold by” Levoit or authorized retailers.

  • ​Local home improvement stores: Some carry Levoit filters, but selection may be limited.

Pro tip: When buying, confirm the filter model number matches your purifier. For example:

  • Levoit LV-PUR131 uses filter model LV-FPR-01.

  • Levoit Core 400S uses LV-FPR-03.

Troubleshooting: What If Your Purifier Still Feels Off After Replacement?

If you’ve replaced the filter but notice lingering issues:

  • ​Check the fan speed: Ensure it’s set to “Auto” or “High” to maximize airflow.

  • ​Clean the purifier exterior: Dust on the intake vents can block airflow—wipe with a dry cloth.

  • ​Test in a smaller room: If the purifier is too large for the space, it may struggle to circulate air effectively.

  • ​Contact Levoit support: If problems persist, reach out to their customer service for model-specific advice.

Final Thoughts: Investing in Filter Replacements Pays Off

Replacing your Levoit air purifier’s filters isn’t just a chore—it’s an investment in your health and comfort. By following this guide, you’ll ensure your purifier runs efficiently, captures more pollutants, and lasts longer. Remember: when in doubt, check your purifier’s manual or Levoit’s support resources. Clean air starts with a well-maintained filter.

Now that you’re equipped with the knowledge, set a reminder to check your filter today—your lungs (and your purifier) will thank you.
