RENPHO is best known for affordable home health gadgets, and its compact air purifiers are a popular first purifier for bedrooms, nurseries and home offices. Like every purifier, they rely on a replacement filter that traps dust, pollen and pet dander, and that filter needs changing every few months to keep the machine working well. The tricky part is that each RENPHO purifier model uses a different filter shape, so the model number on the bottom or back of your purifier is the key to buying the right one.
An important note before you shop: all six filters below are made by third-party brands, namely iSingo, Lichelete and Laukowind, and are designed to fit RENPHO models rather than being official RENPHO filters. They differ mainly by which purifier they fit: two are for the RP-AP088, three are for the RP-AP068, and one set is for the older RP-AP001, RP-AP001S and RP-AP002.

Price and specifications are read from the Amazon product page and can change.
RP-AP088 Filter for RENPHO RP-AP088 Air
Best for: RP-AP088W and RP-AP088B owners with pets
Pros
- Five-stage filtration
- Two filters per pack
- Slide-in install
Cons
- Third-party, not RENPHO-made
- Fits RP-AP088 only
The RP-AP088 Filter for RENPHO RP-AP088 Air Purifier is a 2-pack made by iSingo, listed under the part number RP-AP088-F1 (also noted as RP-AP088-F2). It fits only the RENPHO RP-AP088W and RP-AP088B, the white and black versions of that purifier.
The listing describes a five-stage filter: a pre-filter for large particles such as hair, an intercept coating, a HEPA filter, an activated carbon filter for odors and a net filter. HEPA stands for high-efficiency particulate air, a dense pleated material designed to catch very fine particles. The filter slides in, is marketed for families with pets, and iSingo suggests replacing it every 6 to 8 months depending on use and air quality.
This suits RP-AP088 owners with cats or dogs who want two filters at once. If you prefer the Laukowind version for the same purifier, it is covered at the end of this guide.
2 Pack RP-AP068 Replacement Filter for Simple Spares

2 Pack RP-AP068 Replacement Filter for RENPHO RP-AP068 Air Purifiers
Price and specifications are read from the Amazon product page and can change.
2 Pack RP-AP068 Replacement Filter
Best for: RP-AP068 owners needing a simple spare pair
Pros
- Two filters
- Listed as H13 three-in-one
Cons
- Dimensions conflict within listing
- Sparse feature details
The 2 Pack RP-AP068 Replacement Filter is another iSingo product, designed for the RENPHO RP-AP068 and also listed for the RP-AP068W and RP-AP068B, with a note about the RP-AP068-F2 part.
Its highlight says it is a 3-in-1 filter with an H13 grade true HEPA layer. H13 is a grade used for HEPA material that captures a very high share of fine particles. The listing is thin on details beyond that, and its measurements disagree: the feature text says 10.43 by 4.92 by 2.63 inches, while the specifications say 7.6 by 6 by 5.5 inches. The material is listed as carbon fiber.
It suits an RP-AP068 owner who just wants two replacement filters. If you want a cleaning brush included or more detail about the layers, look at the Lichelete pack next.
4 Pack RP-AP068 Replacement Filter with Cleaning Brush
Lichelete
4 Pack RP-AP068 Replacement Filter For RENPHO Air Pur-ifier RP-AP068
Price and specifications are read from the Amazon product page and can change.
4 Pack RP-AP068 Replacement Filter
Best for: RP-AP068 owners wanting a cleaning brush
Pros
- Cleaning brush included
- Pre-filter, carbon and main filter
- No tools needed
Cons
- Pack count is unclear
- Third-party brand
The 4 Pack RP-AP068 Replacement Filter is made by Lichelete for the RP-AP068, RP-AP068W and RP-AP068B. It uses a 3-in-1 design: a pre-filter, an activated carbon filter and a high-efficiency main filter. The listing claims it captures 99.97% of airborne particles down to 0.3 microns and lists a MERV 13 rating. MERV is a 1 to 16 scale for how well a filter traps particles, with higher numbers catching smaller ones.
The pack count is confusing. The title says 4 pack and the unit count is 4, but the feature list says it contains 2 replacement filters and a cleaning brush. The brush is useful for gently clearing dust from the pre-filter between changes. Filters install without tools, and Lichelete recommends replacing them every 6 months.
This suits an RP-AP068 owner who likes the cleaning brush extra. Confirm the number of filters with the seller before ordering.
RENPHO RP-AP068 True Replacement Filter by Laukowind for Eco-Minded Owners
The for RENPHO RP-AP068 Air Purifiers True Replacement Filter is a 2-pack from Laukowind, listed for the AP068, AP068B and AP068W. Each filter has a 3-in-1 system with a pre-filter, activated carbon filter and main filter.
What sets it apart is an FSC-certified, forest-friendly filter paper, which means the paper comes from responsibly managed sources. It has a collapsible design, is not washable, installs without tools and should be replaced every 6 months. The listing gives a MERV 12 rating, one step below the Lichelete pack’s MERV 13.
This suits an RP-AP068 owner who cares about sustainable materials. If a higher MERV number matters more to you, the Lichelete pack lists MERV 13.
RP-AP001 Filter Set Compatible with RENPHO for Older Models
iSingo
RP-AP001 Filter Set Compatible with RENPHO RP-AP001 Air Purifier
Price and specifications are read from the Amazon product page and can change.
RP-AP001 Filter Set Compatible with RENPHO
Best for: RP-AP001, RP-AP001S and RP-AP002 owners
Pros
- Six-piece set
- Four-stage filtration
- Listed H13 main filter
Cons
- Only fits older RP-AP001 family
- Third-party brand
The RP-AP001 Filter Set Compatible with RENPHO is an iSingo set for the RP-AP001, RP-AP001S and RP-AP002. It is a six-piece package: two main filters, two charcoal filters and two activated carbon filters, making up a four-stage system with a pre-filter.
The main filter is listed as H13 true HEPA material with a MERV 15 rating, the highest listed in this guide. The listing reminds you to remove the plastic wrap before installing and notes that your purifier’s filter indicator light flashes when it is time for a change, with replacement suggested every 6 months.
This is only for owners of the older RP-AP001 family. For more on the purifiers themselves, see our RENPHO air purifier guide.
2 Pack True Air Purifier Filter for RP-AP088 from Laukowind
Best for: RP-AP088 owners stocking a spare set
Pros
- Clear not-fit warning
- Three-in-one filtration
- No tools needed
Cons
- Pack count conflicts in listing
- Not for RP-AP089 models
The 2 Pack True Air Purifier Filter Replacement is Laukowind’s filter for the RP-AP088, RP-AP088W and RP-AP088B, and for the RP-AP088-F1 and RP-AP088-F2 parts. The listing clearly warns that it does not fit the RP-AP089B or RP-AP089W, which is a helpful reminder that similar model numbers are not interchangeable.
Each filter is a 3-in-1 design with a pre-filter, activated carbon filter and main filter, with a round shape measuring about 7.30 inches across and 5.60 inches tall. It installs without tools, and the listing gives an average lifespan of 3 to 12 months. However, the listing contradicts itself on quantity: the title says 2 pack, while a feature line and the unit count say 28. Check the quantity on the product page.
This suits RP-AP088 owners who prefer a 3-in-1 design over iSingo’s five-stage filter.
How to Choose the Right RENPHO Air Purifier Filter
Find your model number first. It is printed on a label on the purifier, often underneath or on the back. RP-AP088, RP-AP068 and RP-AP001 filters are different shapes and sizes, and even close numbers like RP-AP089 do not share filters with the RP-AP088.
Understand third-party filters. None of the six filters here is made by RENPHO. Compatible filters can fit and work, but fit and performance claims come from the seller, and some of these listings contain conflicting sizes and pack counts.
Compare the layers. Most filters here combine a pre-filter, activated carbon for odors and a HEPA-style main filter. If smells from cooking or pets bother you, look for a clear carbon layer.
Plan your replacement schedule. Most listings suggest about every 6 months, so a 2-pack covers roughly a year. If your filters come from another brand of purifier, our guide to a compact purifier replacement filter covers a similar category.
