Replacing an air purifier filter is easy to overlook, but using the wrong model can leave you with a filter that simply does not fit. The Shark HE6FKPET is a genuine replacement HEPA filter made for specific Shark Air Purifier 6 models, with added carbon and Advanced Odor Lock for household smells and VOCs. It is a strong choice when you want the odor-focused Shark filter rather than a basic replacement, but its limited compatibility means you should confirm your purifier model before ordering. This review explains the fit, filtration, replacement schedule, installation, and main tradeoffs so you can decide if it is the right filter for your unit.
Quick Verdict
Rating: 8.5/10, Recommended with caveats
Best For: Owners of compatible Shark Air Purifier 6 models who want a genuine HEPA replacement filter with stronger household odor protection.
Bottom Line: The HE6FKPET combines HEPA particle filtration with carbon-based Advanced Odor Lock in one genuine Shark replacement. Its main limitation is compatibility, since it is designed for selected HE600-series models rather than Shark air purifiers in general.

What Is the Shark HE6FKPET?
The Shark HE6FKPET is a genuine replacement filter for selected Shark Air Purifier 6 models. You install it inside the purifier when the existing filter reaches the end of its usable life. The purifier supplies the fans, sensors, controls, and airflow, while the HE6FKPET performs the filtration.
Its main selling point is the combination of true HEPA filtration and Advanced Odor Lock. The HEPA media handles airborne particles, while the carbon-equipped odor layer is intended to provide heightened protection against smells and VOCs from common household sources such as cooking and cleaning products.
This distinction matters because the original product can be mistaken for an entire air purifier. Buying the HE6FKPET gives you one replacement filter for a compatible purifier. It does not include a purifier unit.
Before You Buy: Check the model number on your Shark air purifier before ordering. The HE6FKPET is made for specific Air Purifier 6 models and should not be assumed to fit every Shark purifier.
Who Should Buy It?
Best For
- You own a compatible HE601, HE601C, HE602, HE602C, HE602NP, or HE612 purifier.
- You want a genuine Shark filter with HEPA filtration and enhanced household odor control.
- Your existing filter is approaching its replacement interval or the purifier’s filter-life indicator says replacement is due.
Skip If
- Your purifier model is not listed as compatible.
- You need a full air purifier rather than a replacement filter.
- You specifically want Shark’s Fumes Lock version, which is a different HE600-series filter model.
Filtration Performance
Shark states that the HE6FKPET captures 99.97% of particles down to 0.3 microns from the air. That specification is more useful than assigning separate capture percentages to dust, pollen, dander, or smoke because filtration performance depends on the particle size and the complete purifier system.
For you, the practical benefit is straightforward. When the filter is installed correctly in a compatible purifier and air is pulled through it, the HEPA media is designed to trap fine airborne particles rather than allowing them to continue circulating through the room.
The filter cannot remove particles that never pass through the purifier, so room placement, airflow, fan setting, and filter condition still matter. A new filter also will not correct blocked vents or other maintenance problems with the purifier itself.
Advanced Odor Lock and Carbon Protection
The HE6FKPET adds carbon-based Advanced Odor Lock to its particle filtration. Shark positions this version for heightened protection against household odors and VOCs, including smells associated with cooking and cleaning products.
This makes the PET version more appealing when odor control is one of your main concerns. A HEPA filter focuses on particles, while the carbon component gives the filter a second role by addressing some gaseous household contaminants and odors.
It is still important to set realistic expectations. An air purifier filter does not remove the source of a persistent smell. Spoiled food, heavy smoke contamination, moisture problems, or other ongoing odor sources should be corrected directly rather than relying only on filtration.
Compatibility and Fit
Compatibility is the biggest buying factor with this replacement filter. Shark currently lists the HE6FKPET for HE601, HE601C, HE602, HE602C, HE602NP, and HE612 models. That broader model list is more reliable than assuming that every purifier carrying the words “Air Purifier 6” uses the same replacement part.
Before purchasing, locate the model label on your purifier and compare it with the supported list. A visually similar filter is not enough to confirm fit.
Pro Tip: Take a photo of your purifier’s model label before shopping for a replacement. It is faster and safer to match the exact model number than to judge compatibility from the purifier’s appearance.
Installation and Setup
Replacing the filter does not require complicated setup, but you should follow the purifier’s owner guide. For HE600-series units, Shark’s instructions call for turning the purifier off and unplugging it before removing or installing a filter.
Remove the filter cover, take out the old filter, remove all packaging from the new filter, insert the replacement, and reinstall the cover. Do not run the purifier with protective wrapping still on the filter.
After installing a new filter, compatible HE600-series guidance instructs you to power the purifier back on and reset the filter-life timer by pressing and holding the Filter Life button for three seconds. Your exact controls can vary by purifier model, so use your unit’s manual if the procedure differs.
How It Performs in Real Use
For Everyday Particle Filtration
In normal household use, the HE6FKPET works as the filtration component inside the purifier. Fine particles carried into the purifier’s airflow are captured by the HEPA media, while the purifier continues circulating filtered air through the room.
For Homes With Pets
The filter can make sense in a pet household because airborne dander and other fine particles are exactly the type of material a HEPA filtration system is intended to capture. The Advanced Odor Lock also gives you more odor-focused filtration than a particle-only design.
For Cooking and Household Odors
The carbon-equipped odor layer is useful when everyday cooking or cleaning smells are part of your concern. It can support odor reduction as air passes through the filter, although ventilation and removing the odor source remain important.
For Long-Term Use
Shark recommends replacement every 6 to 12 months. Actual timing can depend on use and the purifier’s filter-life indication. Replacing the filter when due helps prevent a heavily loaded filter from remaining in service after its intended lifespan.
Cleaning and Maintenance
The HE6FKPET is not designed to be washed and reused. Shark’s HE600-series guidance says the filter should be replaced rather than cleaned with water.
You can maintain the purifier around the filter by keeping intake and vent areas free of dust and debris according to the purifier’s instructions. Always unplug the appliance before cleaning or maintenance.
When you remove an old filter, avoid shaking accumulated debris back into the room. Follow the disposal guidance in your purifier manual and local waste rules.
Pros and Cons
Pros
- Genuine Shark replacement model for several HE600-series Air Purifier 6 units.
- True HEPA filtration with a stated 99.97% particle-capture claim down to 0.3 microns.
- Carbon-based Advanced Odor Lock adds household odor and VOC protection.
- Clear manufacturer replacement guidance of approximately 6 to 12 months.
- Installation does not require special tools under normal HE600-series replacement procedures.
Cons
- Limited compatibility means it is not suitable for every Shark air purifier.
- The filter is disposable rather than washable, so replacement is an ongoing ownership cost.
- It is not Shark’s most odor-and-fume-focused HE600-series filter option if you specifically need the separate Fumes Lock version.
Is It Worth the Price?
The HE6FKPET makes the most sense when you place value on buying a genuine Shark replacement and specifically want Advanced Odor Lock. You are paying for a model designed around the fit and filtration requirements of compatible Shark Air Purifier 6 units rather than choosing a generic filter based only on similar dimensions.
Its value is less compelling if odor control is not a priority or if you are comfortable evaluating compatible third-party filters. It is also worth comparing Shark’s other HE600-series filter variants because the brand offers versions with different levels of odor and fumes protection.
How It Compares to Alternatives
Within Shark’s own HE600-series filter range, the HE6FKBAS is a more basic activated-carbon option, while the HE6FKPRO adds Advanced Odor Lock and Fumes Lock. The HE6FKPET sits between those needs by pairing true HEPA filtration with Advanced Odor Lock without the additional Fumes Lock positioning.
If your main goal is standard replacement filtration with carbon, compare the HE6FKBAS. If you specifically want Shark’s added fumes-focused filtration, compare the HE6FKPRO. The HE6FKPET is the better match when Advanced Odor Lock is the feature you want and your purifier appears on its compatibility list.
Frequently Asked Questions
Is the Shark HE6FKPET an air purifier or just a filter?
It is a replacement filter, not a complete air purifier. You need a compatible Shark Air Purifier 6 unit for the HE6FKPET to function.
Which Shark air purifiers are compatible with HE6FKPET?
Shark currently lists HE601, HE601C, HE602, HE602C, HE602NP, and HE612 as compatible models. Check the model label on your purifier before ordering because similar-looking Shark units may use a different filter.
How often should you replace the Shark HE6FKPET filter?
Shark recommends replacing it every 6 to 12 months. You should also pay attention to the filter-life indicator on your compatible purifier and follow the instructions for your specific model.
Can you wash and reuse the HE6FKPET?
No. Shark’s HE600-series instructions state that the filter is not washable. Keep it away from water and replace it when it reaches the end of its service life.
Does the HE6FKPET help with household odors?
Yes. Shark equips this filter with carbon and Advanced Odor Lock for heightened protection against household odors and VOCs. It should be viewed as part of odor management rather than a substitute for removing the source of a persistent smell.
Do you need to reset the purifier after installing a new filter?
HE600-series instructions call for resetting the filter-life timer after a replacement is installed. On covered models, you press and hold the Filter Life button for three seconds, but you should check your purifier’s manual if its controls differ.
Who should skip the Shark HE6FKPET?
Skip it if your Shark purifier is not on the compatible-model list or if you are actually shopping for a complete purifier. You may also prefer another HE600-series filter if you specifically want the basic carbon version or Shark’s separate Fumes Lock version.
The Bottom Line
The Shark HE6FKPET is a solid genuine replacement for compatible Shark Air Purifier 6 owners who want true HEPA filtration plus Advanced Odor Lock. Its strongest advantage is combining particle filtration with carbon-based household odor protection, while its main limitation is narrow model compatibility and the need for periodic replacement. Buy it when your purifier model matches and odor control matters to you, but choose a different filter if your unit or filtration priorities are different.
