Short answer: The Levoit Vital 100S uses a 3‑in‑1 replacement filter commonly referenced as part number Vital 100S‑RF (retail listings sometimes show Vital 100S‑P). Replace the main 3‑in‑1 filter every 6–12 months, and clean or replace the washable pre‑filter pads about every 3 months depending on dust and pet load.

Which replacement filter fits the Levoit Vital 100S?
Confirm the model label on the bottom or back of your purifier before buying. The correct full replacement for the Vital 100S is the 3‑in‑1 main cartridge (pre‑filter + HEPA layer + activated carbon) referenced by the part name Vital 100S‑RF (some sellers use “Vital 100S‑P” in product titles). That full cartridge is what restores the purifier’s intended particle and odor performance.
Be careful: some lower‑cost listings are pre‑filter kits only — those trap large debris and extend the life of the main filter, but do not include the HEPA or carbon layers. If you only purchase a pre‑filter pack you will not be restoring full filtration capability.
OEM vs vetted generic — quick comparison
The choice usually comes down to guaranteed fit and manufacturer support (OEM) versus lower cost for similar materials (vetted third‑party). Below are replacement listings from our catalog so you can compare actual shop options we vet on AirPurifierFAQ.
| Filter listing (brand) | Type | Composition | Current price | Pros | Cons / Fit notes |
|---|---|---|---|---|---|
| JORAIR Vital 100S Replacement Filter | Generic (vetted) | 3‑in‑1 (advertised; activated carbon + HEPA/pre‑filter) | $32.99 | Sold in 2‑pack; specifically marketed as compatible with Vital 100S and referencing part #Vital 100S‑RF. | Third‑party brand — compare seller ratings and packaging photos to confirm you receive the full 3‑in‑1 cartridge. |
| Cabiclean Vital 100S‑P Replacement Filter | Generic (vetted) | 3‑in‑1 (advertised) | $27.53 | Designed for Vital 100S, includes two filters in the listing; lower unit price than some others. | Seller copy warns to confirm model compatibility; verify the listing matches Vital 100S (not Vital 100 or 200S). |
| HSIAMEN Vital 100S‑RF Pre‑filter | Generic (pre‑filter only) | Electrostatic cotton + nylon outer pre‑filter | $18.99 | Low cost; good to have on hand to protect the main cartridge and reduce large debris buildup. | This listing does NOT include the HEPA or carbon layers — it’s a pre‑filter set only. |
Note on OEM filters: The genuine Levoit part is identified by the part name Vital 100S‑RF (or sold as Vital 100S‑P in some retail titles). Manufacturer (OEM) listings are sometimes available through Levoit or major retailers; product modules on this page and the retailer links we provide will show both genuine and vetted third‑party options so you can choose.
How often to replace and when to choose OEM vs generic
- Main 3‑in‑1 filter (HEPA + activated carbon + pre‑filter): replace roughly every 6–12 months. Replace earlier if you run the unit in high‑pollution environments, around smokers, heavy cooking, or in homes with multiple shedding pets.
- Washable pre‑filter pads or electrostatic pre‑filter replacements: clean or replace about every 3 months — more frequently if you see visible lint or pet hair buildup.
- OEM benefit: guaranteed fit, original packaging and manufacturer support. Some Levoit functions (for example, filter‑life tracking on certain models) may assume genuine filters for the most accurate life estimates.
- Vetted generic benefit: lower per‑filter cost and often sold in multi‑packs. Choose sellers with clear photos showing the 3‑in‑1 layers and good return policies.
How to replace the filter — step‑by‑step (photo prompts A–F)
- Prepare — Unplug the purifier and move it to a flat, well‑lit surface. Photo A: unit unplugged with cover/top removed and placed nearby.
- Open the filter compartment — Depending on your unit, open the rear or top filter door; either pull the tab or press the latch. Photo B: hands opening the filter door.
- Remove the used filter — Grip the filter by its edge or handle and pull it straight out to avoid jamming. If it’s very dirty, pull it outside or over a garbage bag to avoid dust in the room. Photo C: removed used filter showing collected dust/lint (part number visible if present).
- Inspect and clean the chamber — Vacuum or wipe the interior with a dry cloth. Remove lint trapped around the motor inlet or foam pre‑filter. Don’t use liquids inside the chamber. Photo D: close‑up of the empty chamber after cleaning.
- Unpack the new filter — Remove plastic wrap and any shipping foam. Check the label or seller packaging for the Vital 100S‑RF identifier to confirm compatibility. Photo E: new filter unwrapped with label or part number visible next to packaging.
- Install the new filter and reassemble — Slide the cartridge straight into the housing until it seats fully; replace the pre‑filter or washable pad if separate, then close the door. Photo F: new filter installed, cover closed.
- Reset filter indicator — If your purifier shows a filter‑life or maintenance indicator, consult your user manual or the model’s control panel instructions to reset it. If you don’t have the manual, check the control panel for a “filter/reset” symbol or visit the model review and support pages linked below for model‑specific guidance.
Troubleshooting and practical tips
- If the new filter doesn’t seat easily: check orientation marks on the filter and housing. Do not force the cartridge — it should slide in with moderate pressure.
- Pre‑filter only vs full cartridge: if the listing’s photos or description don’t show a HEPA layer and activated carbon, it’s likely a pre‑filter-only pack. Buy a full 3‑in‑1 cartridge if you want full restoration of the purifier’s performance.
- Keep one spare pre‑filter pack on hand (HSIAMEN style) if you live with pets or heavy dust; swapping pre‑filters is cheaper and extends the main filter life.
- When in doubt, compare the product photos and seller copy with the label on your original filter; if the part name Vital 100S‑RF appears in the listing and the cartridge looks like your original, the fit is likely correct.
