Levoit Air Purifier Filters: A Homeowner's Guide
October 7, 2026
A Levoit air purifier is only as good as its filter. Filterbuy has built air filters in its own U.S. plants since 2013, including combination HEPA and carbon purifier filters, and this Levoit air purifier filter guide draws on that experience.
TL;DR
Levoit air purifier filters are model-specific cartridges that pair a pre-filter and fine-particle main filter with activated carbon. Most last 6 to 8 months, less in homes with pets or smoke. Only the pre-filter can be cleaned, and the right replacement matches your exact model name, including any "-P" or "S" suffix.
Key Takeaways
Most Levoit filters stack three stages: a nylon pre-filter, a main filter rated to capture 99.97% of 0.3-micron particles, and activated carbon.
Genuine Levoit filters cost roughly $4 to $8 a month.
In Filterbuy's experience, returning odors are often the first sign a filter is done.
You can clean the pre-filter, but never wash the main or carbon layer.
When the AQI tops 100, pair a MERV 13 HVAC filter with a HEPA purifier in each room.
How Do Levoit Air Purifier Filters Work?
Levoit air purifier filters clean the air in stages, with each layer protecting the one behind it.
Pre-filter (nylon mesh). Catches pet hair and lint before they reach the finer media.
Main filter (HEPA-type media). Levoit rates it to capture at least 99.97% of airborne particles 0.3 microns in size, the HEPA benchmark the EPA describes.
Activated carbon filter. Porous carbon holds on to gas molecules from cooking, pets, smoke, and volatile organic compounds (VOCs).
What we see from the manufacturing side: these layers don't wear out at the same pace. Pleated media clogs gradually and visibly, while carbon quietly stops working once its pores fill. That's why Filterbuy's guidance puts carbon at 3 to 6 months and HEPA media at 6 to 12 (see how HEPA and carbon layers differ). Since a Levoit cartridge holds both, whichever layer gives out first decides your replacement date.
What Types of Filters Do Levoit Air Purifiers Use?
Levoit sells four Core series filter types: Original, Pet Allergy, Toxin Absorber, and Smoke Remover. All are listed on its Core 300 Series Original Filter page and fit the same housing.
*Carbon weights compare the Core P350 pet filter with the standard Core filter, per Trusted Reviews' hands-on review.
Filterbuy's take: Trusted Reviews found that the carbon layer is the main difference between Levoit's pet and standard filters. For pollen or dust, the Original does the job.
How Long Do Levoit Air Purifier Filters Last?
Levoit air purifier filters last about 6 to 8 months under normal use, according to Levoit. The LV-H132 filter is rated for 6 months, while the larger EverestAir-P filter lasts 12 to 15.
How often should you change a Levoit air purifier filter?
For most models, treat 6 to 8 months as an upper limit, and aim for 6 months if:
the purifier runs around the clock on high or Auto,
you share your home with shedding pets, or
someone smokes indoors or you live where wildfire smoke is common.
What does a Levoit filter cost per month?
To show the real cost, Filterbuy divided Levoit's list prices by its replacement intervals.
Filterbuy analysis of Levoit.com list prices (checked Oct. 7, 2026) divided by Levoit's stated intervals. Prices change.
Specialty filters add only about $0.75 to $1.67 a month over the Original. And bigger isn't always pricier: the $99.99 EverestAir-P can cost less per month than the $42.88 LV-H132 filter.
Filterbuy's Check, Clean, Change maintenance routine
This Levoit air purifier filter maintenance routine keeps you on schedule:
Check monthly. Sniff the outlet air and feel the airflow.
Clean every 2 to 4 weeks. Brush or vacuum the pre-filter.
Change at 6 to 8 months, or sooner if a monthly check turns up a problem. Write the install date on the new filter.
For timing by layer, see how often to replace pre-filter, HEPA, and carbon filters.
How to Tell When a Levoit Filter Needs Changing
A Levoit filter usually needs replacing when two or more of these signs appear:
The red Check Filter light comes on. It tracks run time, not condition, so inspect first.
The pleats look gray. Evenly gray or brown media under the pre-filter is loaded.
Smells come back. A sour smell points to saturated carbon; a musty one can mean moisture.
Airflow drops or the fan gets louder. The motor is working harder for less clean air.
Can You Clean or Wash a Levoit Air Purifier Filter?
You can clean a Levoit pre-filter, but never wash the main filter. The Levoit Core 200S manual says only the nylon pre-filter is cleanable, since water collapses fine fibers and ruins carbon. Filterbuy's testing agrees: in a 90-day test published in our guide to washing air purifier filters, a reusable filter lost 15% of its efficiency after its second wash.
How to clean a Levoit air purifier filter (the safe way)
Unplug the purifier and take out the filter.
Brush or vacuum the outer pre-filter.
If your model has a separate washable pre-filter, as the Vital 100S and 200S do (per Air Purifier First's hands-on maintenance guide), rinse it and let it dry completely.
Vacuum the housing, then put the filter back.
Skip soap and compressed air, and keep essential oils away.
How to Change a Levoit Air Purifier Filter
Changing a Levoit air purifier filter takes about five minutes and no tools.
Unplug the purifier.
Open the compartment. Twist off the base cover on Core models, or remove the front or back cover on others.
Snap a photo, then remove the old filter. Vacuum the empty chamber, too.
Unwrap the new filter completely.
Install it and close the cover, with any pull tabs facing out.
Reset the indicator. Hold the filter or reset button for about 3 seconds. That's the Check Filter button on the Core 300 and Sleep Mode on the Core 200S, while the LV-PUR131 needs a small tool for about 5 seconds. Smart models also reset in the VeSync app.
How to Find the Right Filter for Your Levoit Model
The right Levoit air purifier filter is the one whose part number matches your exact model. Filterbuy ships 600+ HVAC filter sizes by the inch, but each Levoit filter is molded for a single model family. Read the label under or behind your purifier, including any "S" or "-P" suffix, then find it below.
†Levoit lists this filter for -P models, and its support team confirms it fits the original Core 300. The LV-PUR131-RF is a flat panel (about 14 x 11.7 x 1.6 in.); most others are cylinders. *Check your owner's manual for the interval.
“Most filter questions we hear aren't about which filter is best. They're about which one fits,” says Michelle Wan, Brand Manager and Air Quality Writer at Filterbuy.
Genuine vs. compatible: Levoit says its filter-life algorithm is designed around genuine filters, so track change dates yourself if you buy third-party. Levoit's user manual library lists each purifier with its filter, and Levoit's support team confirmed the Core 300 cross-fit on the Best Buy Core 300-P-RF listing.

Levoit Air Purifier Filter FAQs
Are Levoit filters interchangeable between models?
No. Levoit's support team says the Core 300-P-RF fits the original Core 300 and the -P models, but not a Core 400S or LV-H132.
Should I still change my HVAC filter if I have a Levoit purifier?
Yes. Your purifier cleans one room; your HVAC filter cleans the whole house. Manufacturers typically recommend a new one every 60 to 90 days, the EPA notes; see how often to change your air filter.
What should I do when the AQI climbs above 100?
Above 100, the air is unhealthy for sensitive groups, according to AirNow's AQI basics. If your home has central HVAC, switch to a MERV 13 air filter, the rating the EPA recommends for home HVAC filters when your system can handle it, and run a HEPA air purifier in each room you use. Check Levoit filters more often, too. Track conditions on Filterbuy's live AQI map.
