Replacing the filters in a Honeywell HPA300 can get confusing because genuine Honeywell filters and third-party replacements often use the same Filter R and Filter A terminology. The product linked in this review is the Cabiclean HPA300 HEPA Filter Replacement Kit, an aftermarket set that combines three HEPA Filter R replacements with six pre-cut activated-carbon pre-filters. It is designed to make a full HPA300-series filter change more convenient, but you still need to confirm your exact purifier model because compatibility differs between the HEPA filters and the carbon pre-filters. This review explains the fit, package contents, replacement schedule, installation, advantages, and limitations so you can decide whether the Cabiclean kit suits your purifier.
Quick Verdict
Rating: Recommended with caveats
Best For: Honeywell HPA300-series owners who want a third-party kit containing both HEPA and pre-cut carbon replacement filters.
Bottom Line: The nine-piece Cabiclean kit gives you three HEPA Filter R replacements plus six pre-cut carbon pre-filters, which is convenient if your purifier uses both types. Its main tradeoff is that it is an aftermarket Cabiclean product rather than a Genuine Honeywell replacement kit, so model compatibility should be checked carefully before purchase.

- This is an aftermarket Cabiclean kit rather than a Genuine Honeywell replacement-filter bundle.
What Is the Cabiclean HPA300 Replacement Filter Kit?
The Cabiclean HPA300 replacement kit is a nine-piece maintenance bundle made for compatible Honeywell air purifiers. Instead of buying the particle filters and carbon pre-filters separately, you receive three rectangular HEPA Filter R replacements and six pre-cut activated-carbon filters in one package.
That combination is particularly practical for the HPA300 because the purifier uses three Filter R elements at the same time. The carbon pre-filter sits in front of the HEPA filters, where it helps catch larger debris and reduce odors before air reaches the deeper filtration layer.
The main buying advantage is convenience. You do not have to cut a universal carbon sheet to size, and you get several replacement pre-filters for later maintenance. The main limitation is equally important: Cabiclean is the brand of this kit. It is designed for Honeywell-compatible machines, but it should not be confused with a Genuine Honeywell replacement filter.
Before You Buy: Check the model label on your air purifier before ordering. The HEPA filters fit a wider range of Honeywell HPA and 5000-series models than the included pre-cut carbon filters, so do not assume every purifier that accepts the HEPA Filter R also accepts the supplied carbon sheet.
Who Should Buy It?
Best For
- Owners of a compatible HPA300-series purifier who need all three HEPA filters at once.
- Buyers who prefer pre-cut activated-carbon filters instead of trimming universal filter material.
- People who want several carbon-filter replacements included for routine maintenance.
Skip If
- You specifically want Genuine Honeywell-branded replacement filters.
- Your purifier model is not listed as compatible with the filters you need.
- You only need a single HEPA replacement rather than a multi-filter maintenance kit.
Compatibility and Fit
The three HEPA Filter R replacements are listed for a broad group of Honeywell purifiers, including models in the HPA090, HPA100, HPA200, HPA300, and selected HPA5000 families. Listed examples include HPA100, HPA200, HPA204, HPA250, HPA300, HPA304, HPA5100, HPA5200, HPA5220, HPA5250, HPA5300, HPA5350, and HPA8350.
The six pre-cut carbon filters have a more focused compatibility list. They are intended primarily for HPA300-type machines, including HA/HPA300, HPA304, HPA3300, HPA5300, and HPA8350-series models. That difference matters if you own one of the smaller HPA units. You may be able to use the HEPA Filter R replacements while the included carbon pieces are not sized for your machine.
Pro Tip: Read the model number from the purifier’s label rather than relying only on its appearance. Similar Honeywell housings can use different quantities or sizes of Filter R and pre-filter material.
HEPA and Activated-Carbon Filtration Roles
The two filter types have different jobs. The pleated HEPA-style Filter R replacements handle finer airborne particles that pass through the front layer. The activated-carbon pre-filter sits ahead of the HEPA filters and is intended to help with odors while also catching larger debris before it reaches the main filtration media.
Using both layers also helps protect airflow. As dust, hair, lint, smoke residue, and other contaminants build up, filter resistance can increase. A heavily loaded filter can reduce the amount of air moving through the purifier, which is why replacement timing should be based on both the recommended interval and the condition of the filters.
The original version of this review applied a precise 99.97% filtration figure to the product. Because this linked product is a third-party Cabiclean replacement and the current listing does not clearly document that exact efficiency specification for this ASIN, you should not assume it has the same independently certified performance claims as a Genuine Honeywell Filter R.
When Should You Replace the Filters?
Cabiclean recommends replacing its HEPA Filter R elements about every 6 to 12 months and the activated-carbon pre-filter about every 2 to 3 months, depending on your use and environment. Honeywell’s general HPA-series guidance is about 12 months for HEPA filters and three months for pre-filters.
Those numbers are guidelines rather than fixed expiration dates. Homes with heavier dust, pet dander, smoke, frequent cooking odors, or longer purifier run times can load a filter faster. A cleaner environment may allow the filter to remain useful longer.
Reduced airflow and increased purifier noise are practical warning signs. Honeywell notes that a high concentration of particles can block filter pores and restrict air movement. You should also inspect the filter periodically rather than waiting only for a calendar date.
Installation and Maintenance Tips
Turn the purifier off and unplug it before opening the front grille. Remove the used HEPA filters, then install the replacement Filter R elements in the purifier housing. On HPA300-style units, the three HEPA filters occupy the filter compartment together.
Next, position the carbon pre-filter over the HEPA filters and secure it using the attachment points provided in your purifier. The HPA300 housing uses attachment areas around the filter opening to keep the pre-filter in place. Reinstall the front grille securely before reconnecting power.
If your purifier’s filter indicator remains illuminated after replacement, use the reset procedure in the owner’s manual. Honeywell’s HPA-series guidance generally calls for holding the illuminated filter-check control for about two seconds after the new filter is installed.
Do not wash this type of disposable HEPA replacement filter. Washing disposable HEPA or pre-filter media can damage its structure and reduce filtration performance. Replace dirty disposable filters instead of trying to restore them with water.
How It Performs in Real Use
For a Full HPA300 Filter Change
This package is particularly convenient when your HPA300 needs its complete HEPA set replaced. Because the kit includes three Filter R elements, you do not need to buy three individual units to fill the purifier’s main filter compartment.
For Homes With Regular Odor Exposure
The six carbon pre-filters provide several replacement pieces for environments where cooking odors, pets, smoke, or other odor sources load the front filter more quickly. The carbon layer is replaceable separately from the three main HEPA filters, so you can change the pre-filter more often when needed.
For Routine Maintenance
The pre-cut design removes an extra step from maintenance. Instead of measuring a universal carbon roll, you can fit a correctly sized piece to a compatible HPA300-series housing. That is useful when you want filter changes to remain simple and repeatable.
For Long-Term Ownership
A multi-piece bundle can reduce the number of separate filter orders you need to place. Still, store unused filters in a clean, dry location and keep them protected from dust until you are ready to install them.
Common Mistakes to Avoid
- Do not order solely because your purifier uses the words “Filter R.” Confirm the complete model number.
- Do not assume the HEPA-filter compatibility list and carbon-filter compatibility list are identical.
- Do not run the purifier with badly clogged filters simply because the suggested replacement date has not arrived.
- Do not wash disposable HEPA replacement media.
- Do not forget to remove any protective packaging from a new filter before installation.
- Do not confuse this Cabiclean aftermarket kit with a Genuine Honeywell replacement bundle.
Compatibility and Safety
Filter replacement involves the air path of an electrical appliance, so you should always turn off and unplug the purifier before opening the housing. Install the filters only in the orientation required by your specific purifier and make sure the front grille is fully secured afterward.
Do not force an incorrectly sized filter into the cabinet. A poor fit can leave gaps around the filter media or interfere with the front panel. If your model number is not clearly covered by the listing, check your purifier manual before using the kit.
This filter kit is intended for air-purifier maintenance. It is not a medical device, and replacing a filter should not be treated as a substitute for professional guidance about indoor-air or health concerns.
Pros and Cons
Pros
- Includes all three HEPA Filter R elements needed for a standard HPA300 installation.
- Six pre-cut activated-carbon filters reduce the need to measure and trim universal material.
- HEPA Filter R replacements support several Honeywell HPA and 5000-series models.
- Separate carbon pre-filters can be replaced more frequently than the HEPA filters.
- Nine-piece package gives you both main and front filtration components in one order.
Cons
- It is an aftermarket Cabiclean product, not a Genuine Honeywell replacement kit.
- The carbon pre-filters do not share the full compatibility range of the HEPA Filter R replacements.
- Replacement timing still varies with your environment, so the included quantity does not guarantee a fixed number of months of use.
HEPA vs. Activated Carbon Filters
The HEPA and activated-carbon components should not be viewed as interchangeable. The main Filter R elements are designed to handle finer particulate filtration, while the front carbon pre-filter helps collect larger debris and reduce odors before air reaches the deeper filter media.
This is also why their replacement schedules differ. A carbon pre-filter can become loaded with dust, hair, and odor-producing compounds well before the main HEPA filters need replacement. Changing the pre-filter on time may help maintain airflow and keep the main filter from collecting as much large debris.
For a compatible HPA300 setup, the best maintenance approach is to treat the HEPA filters and carbon pre-filter as two separate consumables with different replacement intervals.
Is It Worth the Price?
The value of this Cabiclean kit comes mainly from what is included rather than from any specific advertised price. You receive three HEPA Filter R replacements and six pre-cut carbon filters in one package, so it can make sense for an HPA300 owner who would otherwise need to purchase multiple filter pieces separately.
It is worth considering if convenience and bundled replacement quantity matter more to you than buying the purifier manufacturer’s branded filters. Buyers who specifically want Genuine Honeywell filtration should compare the current cost of Honeywell’s own Filter R and Pre-Filter A options before deciding.
The biggest value limitation is compatibility. A large bundle is only useful if both filter types fit your exact purifier, so confirm that point before comparing the package on price alone.
How It Compares to Alternatives
A Genuine Honeywell HPA300 filter bundle is the clearer choice if manufacturer-branded replacement media is your priority. Honeywell’s own HPA300 maintenance bundle pairs three Genuine Filter R elements with a carbon pre-filter, while the Cabiclean package focuses on giving you more pre-cut carbon replacements in one aftermarket kit.
You can also compare third-party kits from brands such as VEVA, which has offered HPA300 replacement sets containing HEPA and activated-carbon filters. The Cabiclean option makes the most sense when its exact compatibility and nine-piece package match your maintenance needs.
Getting Support for the Filters
Because the linked product is manufactured by Cabiclean, questions about the replacement kit itself, including fit, packaging, defects, or missing pieces, should be directed to Cabiclean or the seller through the product’s Amazon support options.
Questions about operating the Honeywell purifier, resetting its filter indicator, or identifying the correct replacement-filter type should be checked against the manual and support information for your exact Honeywell purifier model. Keeping those two support channels separate helps avoid confusing an aftermarket filter issue with an air-purifier issue.
Frequently Asked Questions
Is this a Genuine Honeywell HPA300 filter?
No. The linked product is a Cabiclean aftermarket replacement kit designed for compatible Honeywell purifiers. Choose a Genuine Honeywell Filter R product if manufacturer-branded replacement media is important to you.
How many filters are included?
The package contains nine pieces in total: three HEPA Filter R replacements and six pre-cut activated-carbon Filter A pre-filters. The three HEPA filters provide the quantity used together in an HPA300 installation.
How often should you replace the Cabiclean HEPA filters?
Cabiclean’s listing recommends a replacement interval of roughly 6–12 months for the HEPA Filter R elements. Treat that as a guideline because heavy dust, smoke, pet dander, and longer operating hours can shorten useful filter life.
How often should you change the carbon pre-filter?
The seller recommends replacing the carbon pre-filter about every 2–3 months. Check it sooner if your home has heavy dust, pets, smoke, or frequent odor exposure.
Can you wash and reuse these HEPA filters?
You should not wash disposable HEPA replacement filters. Water can damage disposable filter media and reduce its ability to work as intended, so replace a loaded filter rather than washing it.
Will every Filter R-compatible purifier use the included carbon pre-filters?
No. The HEPA Filter R replacements have a broader compatibility list than the six pre-cut carbon filters. Confirm the compatibility of both components with your model before purchasing the complete kit.
Why is airflow lower or the purifier louder than before?
A heavily loaded filter can restrict airflow and make the purifier sound different. Inspect the HEPA filters and pre-filter for heavy buildup and replace them when needed instead of relying only on the calendar.
The Bottom Line
The Cabiclean HPA300 replacement kit is a practical choice if you own a compatible purifier and want three HEPA Filter R replacements plus six pre-cut carbon pre-filters in one package. Its strongest advantage is the convenient filter quantity and pre-cut design, while its main limitation is that it is an aftermarket product with different compatibility ranges for the HEPA and carbon components.
Buy it when your exact model is supported and a bundled third-party replacement set fits your priorities. Skip it if you specifically want Genuine Honeywell filters or if your purifier is not clearly listed as compatible with both filter types.
