PARTU Air Purifier Replacement Filters: What Fits Your Model

PARTU is best known for compact desktop and bedroom air purifiers, mainly the BS-03 and the larger BS-08. Once you own one, the part you keep buying is the filter, and that is what most people searching for a PARTU air purifier filter really need. One honest note up front: none of the four filters below is made by PARTU itself. They come from third-party makers (isinlive, Cabiclean and Nispira) and are sold as compatible with PARTU purifiers, so the single most important step is checking your purifier’s model number before you order.
Three of these filters are built for the BS-03 and differ mainly in pack size and in how clearly the listing describes the filter layers, while the fourth, from Nispira, fits only the BS-08.

BS-03 Replacement Filter Compatible with PARTU
Best for: BS-03 owners wanting a basic 3-stage refill
Pros
- Pre-filter, main and carbon layers
- No tools needed to swap
- FSC-certified paper
Cons
- Size figures differ within listing
- Pack count unclear in title
The BS-03 Replacement Filter Compatible with PARTU is sold under the isinlive brand and is made for the PARTU BS-03 (which the listing also calls Part U and Part X) and the Slevoo BS-03. It uses a 3-in-1 design: a pre-filter that catches larger bits like hair and lint, a pleated main filter wrapped 360 degrees around the core, and an activated carbon layer that targets odors and gases. The paper is FSC-certified, which means it comes from forests managed under the Forest Stewardship Council’s standards.
The listing recommends a change every 6 months, or sooner depending on air quality and how often you run the purifier, and says no tools are needed. Two details are fuzzy. The features give the size as 5.2 by 3.6 inches while the specs say 5.2 by 5.2 by 3.6 inches, which is most likely diameter and height for a round filter, and the specs list 2 items even though the title does not mention a pack size. It also does not use the word HEPA for its main layer, unlike the Cabiclean filters below.
This suits a BS-03 owner who wants a straightforward replacement and does not need a large stockpile. If you want the HEPA wording spelled out, look at the two Cabiclean packs instead.

4 Pack BS-03 Replacement Filter
Best for: BS-03 owners stocking up for years
Pros
- Four filters in the pack
- HEPA plus carbon layers
- 3-6 month change guide
- States not for BS-01
Cons
- Spec says 1 item, title says 4 pack
The 4 Pack BS-03 Replacement Filter from Cabiclean fits the PARTU BS-03 (Part U and Part X), the Slevoo BS-03 and the Allouncer air purifier, according to the listing, and it clearly states it is not for the BS-01. It uses three stages: a fine preliminary filter, a HEPA filter and a carbon filter for household odors from pets, cooking and smoking.
HEPA stands for high-efficiency particulate air. The listing says this filter captures 99.97% of airborne particles as small as 0.3 microns, which is the standard way HEPA performance is described. Cabiclean suggests replacing it every 3 to 6 months depending on your environment and usage. The one inconsistency is that the title and features say 4 pack while the specification field lists 1 item, so confirm the count on the order page.
This is the pick for a BS-03 owner who runs the purifier every day, lives with pets, or simply never wants to be caught without a spare. At the 3-month end of the schedule, four filters cover about a year.
Nispira BS-08 3-in-1 HEPA Air Filter for the Larger PARTU
Nispira
Nispira BS-08 3-in-1 HEPA Air Filter Replacement Compatible with Partu Air Purifier BS-08, 1 Pack
Price and specifications are read from the Amazon product page and can change.
Nispira BS-08 3-in-1 HEPA Air Filter
Best for: Owners of the larger PARTU BS-08
Pros
- Made only for BS-08
- HEPA plus activated carbon
- Slide-in mounting
Cons
- Does not fit BS-03
- Single filter per pack
The Nispira BS-08 3-in-1 HEPA Air Filter is the only filter here for the PARTU BS-08, and the description is blunt: BS-08 only, not for the BS-03. It measures 6.5 by 6.5 by 5 inches, noticeably bigger than the BS-03 filters, and slides into place. The materials listed are meltblown fiber HEPA and activated carbon, and the specs give a MERV 16 rating. MERV is a scale for how well a filter catches particles, and 16 sits at the top of the common range.
The listing does not describe a replacement schedule and does not break down what the three layers are beyond HEPA and carbon. You get one filter per pack. If you own a BS-08, this is your choice in this lineup; if you own a BS-03, skip it entirely, because it will not fit.
2 Pack BS-03 Replacement Filter for a Year of Spares
Cabiclean
2 Pack BS-03 Replacement Filter for PARTU BS-03 & Slevoo BS-03 Air Purifier
Price and specifications are read from the Amazon product page and can change.
2 Pack BS-03 Replacement Filter
Best for: BS-03 owners wanting a year of spares
Pros
- Two filters in the pack
- Pre-filter, HEPA and carbon
- States not for Slevoo BS-01
Cons
- Specs list Slevoo BS-03 only
- Pack count wording is unclear
The 2 Pack BS-03 Replacement Filter is Cabiclean’s smaller pack. The features list compatibility with the PARTU BS-03 (Part U and Part X) and the Slevoo BS-03, and warn that it does not fit the Slevoo BS-01. It uses a 3-in-1 system of pre-filter, HEPA filter and activated carbon, made with FSC-certified paper. Cabiclean suggests a change every 6 months, so two filters cover roughly a year of use.
Note that the specification fields only name the Slevoo BS-03, while the title and features name PARTU too. The specs also list both 2 items and 2 packs, which leaves it unclear whether you get two filters or four; the title says 2 pack, which is the safer reading. This model suits a BS-03 owner who wants HEPA wording and a spare in the drawer without buying four at once.
How to Choose the Right PARTU Air Purifier Filter
Find your model number first. Look on the bottom or back label of your purifier. If it says BS-03 (sometimes shown as Part U or Part X), choose one of the three BS-03 filters. If it says BS-08, the Nispira filter is the only fit here. The two sizes are not interchangeable.
Decide how many spares you want. Filters are a running cost, like printer ink. The 4 pack suits heavy users, the 2 pack covers about a year at the 6-month schedule, and the isinlive filter is fine for a quick refill.
Know how often to change it. The listings suggest every 3 to 6 months. Change sooner if you have pets, smoke in the home, or notice the filter turning grey. A clogged filter makes the fan work harder and moves less clean air. Pet owners dealing with litter smells may also like our guide to a litter box air purifier.
Check the layers you need. All four include activated carbon for odors. The Cabiclean and Nispira listings use the term HEPA for their particle layer; the isinlive listing describes a multi-layer main filter instead.
Know when to size up. These small purifiers suit a bedroom or desk. If you are trying to clean the air in an open living area, a larger unit makes more sense, and our guide to air purifiers for large rooms explains what to look for.
FAQ
Which filter fits my PARTU purifier?
Check the model label. BS-03 owners can use the isinlive filter or either Cabiclean pack. BS-08 owners need the Nispira BS-08 filter, which the listing says does not fit the BS-03.
Are these official PARTU filters?
No. All four are third-party filters made by isinlive, Cabiclean and Nispira and sold as compatible with PARTU purifiers. The listings describe the fit; they do not claim PARTU makes them.
How often should I change a PARTU filter?
The BS-03 listings suggest every 6 months, and the Cabiclean 4 pack says every 3 to 6 months depending on your environment. The Nispira BS-08 listing does not specify an interval.
Will a Slevoo BS-03 filter work in a PARTU BS-03?
The three BS-03 listings here all say they fit both PARTU and Slevoo BS-03 purifiers, which suggests the two share the same filter size. None fits the Slevoo BS-01.
What does 3-in-1 mean on these filters?
It means three filtering layers in one piece: usually a pre-filter for large particles, a fine or HEPA layer for dust and dander, and activated carbon for smells.
Do I need tools to replace the filter?
The isinlive and Cabiclean listings say no tools are needed. The Nispira listing describes a slide-in mount, which also suggests a tool-free swap.
