The right Cuisinart air purifier filter is the one whose model code matches the purifier sitting in your room. Cuisinart names its filter packs after the machine they fit: the CAP-250 takes a CAP-250FPK style filter, the CAP-500 takes the CAP-500FPK, and the CAP-1000 takes a CAP-1000 filter. Get the code right first, then decide whether you want a genuine Cuisinart Purxium pack or a third-party replacement that promises the same fit.
This article covers four filter packs across three Cuisinart models. Two are genuine Cuisinart products (the CAP-250 HEPA 13 carbon pack and the CAP-500FPK), and two are third-party replacements sold under other brand names (a Horserdy four-pack for the CAP-500 and a PZHARQG single filter for the CAP-1000). We compared the listings, specifications and stated compatibility rather than running our own lab tests, and we flag clearly where a listing leaves out details you would want to know before you buy.

Best for
CAP-500 owners wanting a stack of spares
Pros
- Four filters in one pack
- H13 True HEPA with carbon
- Tool-free install
Cons
- Third-party Horserdy, not Cuisinart
- No runtime rating listed
Start with the most important detail: the CAP-500FPK Replacement Filters for Cuisinart CAP-500 are made by Horserdy, not by Cuisinart. The listing uses the CAP-500FPK name to describe what the filters replace, and it states they are designed to fit the Cuisinart CAP-500 Air Purifier. That is useful if you want a generous supply of spares, but it is still a third-party part, so you are trusting Horserdy’s fit and material claims rather than Cuisinart’s.
What you get is a four-pack of combination filters. Each one pairs H13 True HEPA media, which the listing says captures airborne particles as small as 0.3 microns, with an activated carbon layer aimed at odors and smoke. The listing also gives a MERV rating of 13 and dimensions of 9.61 by 7.11 inches with a 1.26-inch thickness. It does not state a runtime rating or a recommended replacement interval, so you will need to lean on your purifier’s filter indicator or your own schedule.
This pack suits a CAP-500 owner who runs the purifier hard in a gaming room or streaming space and would rather keep a stack of filters in the closet than reorder often. If brand-genuine parts matter more to you than quantity, the official CAP-500FPK further down is the better fit.
- Four filters per pack for long-term spares
- H13 True HEPA plus activated carbon in each filter
- Listed MERV 13 rating
- Tool-free installation according to the listing

Best for
CAP-250 owners in smaller rooms
Pros
- Genuine Cuisinart Purxium filter
- 2,500-hour minimum runtime
- Clear replacement schedule
Cons
- Fits CAP-250 only
- Two filters per pack
The Cuisinart HEPA 13 Carbon Filter 2 is the genuine Cuisinart replacement for the CAP-250, and the description calls it the CAP-250FPK 2 in 1 filter pack. Each of the two filters combines H13 high-grade HEPA media with an active carbon filter in one piece, so you swap a single unit rather than juggling separate layers.
Cuisinart backs this pack with clear numbers. The listing claims capture of up to 99.9 percent of airborne particles 0.1 micron or larger, along with cooking odors, smoke and VOCs. It gives a minimum rating of 2,500 hours of run time, which translates to up to six months at 12 hours a day or about three months if the purifier runs around the clock. Coverage is listed as up to 250 square feet, cleaned twice every hour.
That 250-square-foot rating tells you who this is for: someone running a CAP-250 in a bedroom, a dorm, or a compact desk corner where a console and PC share the space. It will not fit a CAP-500 or CAP-1000, so check your purifier’s label before ordering.
- Two combination HEPA 13 and carbon filters
- 2,500-hour minimum runtime rating
- Rated for rooms up to 250 sq. ft.
- Targets smoke, dust, odors, pet dander, pollen and VOCs

Best for
CAP-1000 owners needing one replacement
Pros
- 3-in-1 pre, main and carbon layers
- Sized for the larger CAP-1000
Cons
- Third-party PZHARQG, not Cuisinart
- HEPA grade and lifespan not specified
The CAP-1000 Replacement Filter for Cuisinart CAP-1000FPK is a single filter made by PZHARQG, another third-party brand. The listing states it is designed to be compatible with the Cuisinart CAP-1000FPK air purifier, but its own specification line for compatible devices simply says “Air Purifier”, so double-check the fit against your unit’s filter slot and the listed 12.6 by 9.4 inch footprint with a 1.4-inch thickness.
The filter uses a 3-in-1 layout: a pre-filter, a high-efficiency filter and an activated carbon filter. The listing does not specify a HEPA grade, a particle size, a runtime rating or a coverage area, and the material is listed as pleated polypropylene. It only says to replace the filter regularly. That is thinner information than you get with the genuine Cuisinart packs, and it is worth knowing before you buy.
This option suits a CAP-1000 owner who needs one replacement now and is comfortable with a third-party part. It is the only CAP-1000 filter in this roundup, so there is no genuine alternative here to compare it against.
- Pre-filter, high-efficiency and carbon layers in one unit
- Pleated construction

Best for
CAP-500 owners who want genuine filters
Pros
- Official Cuisinart CAP-500FPK
- Rated for 500 sq. ft. rooms
- 2,500-hour runtime
Cons
- Two filters versus four in rival pack
The Cuisinart CAP-500FPK Air Purifier Replacement Filters are the official Cuisinart pack for the CAP-500. You get two combination filters, each pairing H13 high-grade HEPA media with active carbon, labeled under Cuisinart’s Purxium filter name.
The performance claims mirror the smaller CAP-250 pack but scale up for a bigger room. The listing states capture of up to 99.9 percent of airborne particles 0.1 micron or larger, a 2,500-hour runtime, and a lifespan of up to six months, or three months when the purifier runs 24/7. Coverage rises to 500 square feet cleaned twice every hour, and the listed contaminants include wildfire smoke as well as dust, odors and VOCs.
This is the pick for a CAP-500 owner who wants the manufacturer’s own part and published runtime numbers, for example in a living room with a big-screen setup or a shared gaming space. You get two filters instead of four, so if volume is your priority the Horserdy pack covers more months per box, with the third-party trade-off noted above.
- Genuine Cuisinart Purxium CAP-500FPK
- Two HEPA 13 and carbon combination filters
- Rated for rooms up to 500 sq. ft.
- 2,500-hour runtime rating

NOTES
Buying Tips for Cuisinart Air Purifier Filters
Match the model code before anything else. A CAP-250 filter will not fit a CAP-500, and a CAP-500 filter will not fit a CAP-1000. The model number is printed on the purifier itself, and it lines up with the filter pack name. If you are still shopping for the purifier rather than the filter, our guide to air purifiers for homes with pets covers what room size and filter type to look for.
Decide how you feel about third-party filters. Genuine Cuisinart packs publish runtime and coverage numbers; the two third-party packs here either skip those details or describe compatibility in general terms. Third-party filters can be a sensible way to keep spares on hand, but you take on more of the fit risk. The same trade-off applies across brands, as we cover in our look at air filter replacement options.
Plan replacements around how long your purifier runs. In a gaming room where the purifier is on for long sessions, a filter rated for six months at 12 hours a day may need changing closer to the three-month mark. Carbon layers lose their odor-absorbing ability as they saturate, so a filter can still look fine while smelling less fresh.
FAQ
Which Cuisinart filter fits my air purifier?
Use the filter named after your purifier: CAP-250FPK style filters for the CAP-250, CAP-500FPK for the CAP-500, and a CAP-1000 filter for the CAP-1000. The model number on your purifier is the quickest way to confirm.
Is the Horserdy CAP-500FPK pack made by Cuisinart?
No. It is a third-party replacement from Horserdy that uses the CAP-500FPK name to show what it replaces. The genuine Cuisinart CAP-500FPK is a separate listing with two filters per pack.
How often should I replace a Cuisinart HEPA 13 carbon filter?
Cuisinart’s listings give a 2,500-hour runtime, which works out to up to six months at 12 hours a day or about three months if the purifier runs all day and night.
Does the CAP-1000 replacement filter use true HEPA media?
The listing describes a high-efficiency filter layer between a pre-filter and carbon filter but does not specify a HEPA grade or particle size. If a certified HEPA rating matters to you, that information is missing from this listing.
Do these filters help with smoke and odors in a gaming room?
All four include activated carbon, which is the part of a filter that absorbs odors and smoke. The genuine Cuisinart packs also list VOCs and cooking odors among the contaminants they target.
