The best Shark air purifier replacement filters depend on your purifier model, not just the Shark brand. For another brand, compare Philips air purifier replacement filters.

Leemone is the top choice for HE400-series owners because it includes 1 HEPA filter and 2 replaceable pre-filters, while ShufudeJa is the strongest HP102-family pick.

Before choosing a replacement, check the model printed on your purifier and compare the filter shape, part number and dimensions. A filter made for HE400 will not automatically fit an HP102 or HP201 unit.

This roundup compares replacement filter compatibility across Shark purifier models and coverage sizes. We checked the stated filter layers, pack contents, model lists and care guidance.

Our score weighs specs, features and buyer feedback against what you're shopping for.

The best Shark air purifier replacement filters by model

The best Shark air purifier replacement filter is the one that matches your exact model and part number. Score comes after fit, so a lower ranked filter with the right shape will serve you better than a top pick made for another family.

The picks below are ordered by score, with HE400, HP102, HE601 and HP201 families covered separately. That split matters because rectangular HE400 units use HE4FK parts, while HP102 family units use HE1FK parts and HP201 family units use HE2FK parts.

Use this section as a shortlist, not as a final check. Find your purifier model first, then read the product notes for that group and compare part numbers before you order.

A spare filter is only useful when it slides in or drops in cleanly and lets the purifier run without a gap around the edge.

• 1 replacement filter

BUXEBUX covers a wide group of Shark Max and Clean Sense models, including HP302, HP301, HP201 and HP202. It is useful when your model belongs to that larger family rather than the round HP102 group.

See it on Amazon

• Broad HP and HC compatibility
• H13 True HEPA layer

• 6 to 12 month filter life

Fette Filter is aimed at HP100 and HP102 families, with additional HC, UA and pet-model compatibility. Its direct part-number matches help when you are replacing an existing HE1FK filter.

See it on Amazon

Pros

• Broad HP100-series fit
• Lists several direct part numbers
• Tool-free installation

Cons

• Only 1 filter included
• MERV 8 is lower than several other picks here

1. Leemone Filter Replacement for Shark Air Purifier: Best for HE400 pre-filter savings

Leemone is the best overall choice for Shark HE400-series owners who want a main replacement plus extra pre-filters. The package includes 1 HEPA filter and 2 replaceable pre-filters, so you can change the pre-filter more often without replacing the main filter each time.

It fits Shark HE400, HE401, HE401C, HE401NP, HE402, HE402C, HE405 and UA415 models. Compare those names with the part numbers HE4FKBAS, HE4FKPET, HE4FKPETMB and HE4FKPRO before ordering.

The 3-stage design combines an H13 True HEPA filter, activated carbon and a pre-filter. Leemone states that the filter captures 99.97% of airborne particles as small as 0.3 microns, including pollen, dust and pet dander, while the carbon layer addresses household odors.

The filter measures 17 x 15.09 x 1.59 in and uses a slide-in mounting style. Leemone recommends changing the pre-filter every 3 months and the HEPA filter every 6 to 12 months, depending on use and local air quality.

After installing it, press and hold the purifier's Filter Life button for 3 seconds to reset the timing system. The unit should beep when the reset is complete.

2. ShufudeJa 2 Pack HP102 Replacement Filter: Best for HP102 two-filter backups

ShufudeJa is the best fit for HP102 owners who want 2 replacement filters in one pack. Each filter measures 7.56 in in diameter and 7.17 in in height, which makes the round size especially important to verify before ordering.

The compatibility list includes HP100, HP102, HP152, HP153, HP100C, HP102C, HP105, HP102PET, HC450, HC450C, HC451, HC452, HC452C, HC455, HP130, HP132, UA205, UA455 and UA505 models.

This filter uses a multi-filter design for dust, hair, pet dander and pollen, with a carbon layer for household odors and VOCs. ShufudeJa says the filters use FSC-certified paper.

Do not use this pick for HP201, HP202 or HC501. Those models belong to different filter families, so the lower price of a mismatched filter would not solve the replacement need.

The recommended replacement interval is 6 to 12 months, based on air quality. Tool-free installation makes it suitable for keeping a spare filter ready for the next change.

3. FCFMY 2 Packs Upgraded 3-in-1 HE601 Replacement Filter: Best for HE601 odor control

FCFMY is the leading choice for Shark HE601 and HE602 owners who want a 2-filter pack with activated carbon. The filters are made for the advanced odor lock 6-fan models and use 3 layers: a pre-filter, main filter and activated carbon filter.

The carbon layer is aimed at household odors such as cooking smells, pet-related odors and furniture fumes. The main filter handles dust and finer airborne particles, while the pre-filter provides the first layer for larger particles.

Because the compatibility list names only HE601 and HE602, this is a focused option rather than a broad Shark replacement. Confirm that model number before choosing it for another Shark purifier.

When the purifier's Filter Life button flashes, install the replacement and hold that button for 3 seconds. The unit should beep after the timing system resets.

FCFMY recommends replacing the filter every 6 to 12 months, depending on indoor air conditions. The 2-pack gives you a second filter for the next scheduled change.

4. FCFMY 1 Pack HE400 Replacement Filter Compatible: Best for one HE400 refresh

This FCFMY filter suits Shark HE400, HE401, HE402 and HE405 owners who need one replacement filter. It combines an H13 True HEPA filter, activated carbon and a pre-filter in a single 3-in-1 design.

The rectangular filter measures 15.08 x 1.59 x 1.59 in. Its stated MERV 18 rating and H13 True HEPA layer make it a strong fit for buyers comparing filtration details within the HE400 family.

FCFMY lists HE4FKPET as the replacement part number. Compare that number and the purifier model before ordering, since the product data specifically names the HE400-series models rather than every Shark air purifier.

The Filter Life button flashes when the purifier calls for a change. After installation, hold the button for 3 seconds to reset the system and wait for the beep.

FCFMY recommends replacement every 6 to 12 months, based on the use environment. Choose this pack when one filter is enough and you do not need extra pre-filters or a second replacement.

5. iSingo HP201 Filter Replacement for Shark HP201: Best for HP201 and HP202 owners

iSingo is the best match for Shark HP201, HP202 and HP232 owners who need a round replacement filter. It also fits listed HP300-series, HC500-series, UA and AP models, including HP301, HP302 and HC502.

The filter measures 11.9 in high and 8.7 in in diameter. Its round shape separates it from the rectangular HE400 filters and the smaller round HP102-family filters.

The 3-stage design combines a pre-filter, activated carbon filter and HEPA filter. iSingo states that it cleans up to 99.98% of airborne particles under the cited test method and particle range, while the carbon layer addresses unwanted odors.

Do not use this filter for HP102 or HC452. Those purifiers require a different filter family, even though both groups use round filter formats.

The package includes 1 filter. iSingo recommends replacement every 6 to 12 months, depending on how often the purifier runs and the air conditions in the room.

For another model-specific comparison, see our Winix 5510 air purifier review.

6. Pulluty HE401 Replacement Filter for Shark Air Purifier 4: Best for a simple HE401 swap

Pulluty is a simple 1-filter replacement for Shark Air Purifier 4 models. It fits HE401, HE402, HE405 and the listed HE400 models, and it replaces part number HE4FKBAS.

The filter combines an H13 True HEPA layer with activated carbon. Pulluty states that the filter captures 99.97% of airborne particles as small as 0.3 microns, including pet hair, pet dander and odors.

This option is useful when you want one replacement without a multi-filter package. It does not include extra pre-filters, so buyers who want separate pre-filter changes may prefer the Leemone set.

Pulluty recommends replacing the filter set every 3 to 6 months for optimal performance. That interval is shorter than the 6 to 12 month guidance attached to several other products here, so consider your use pattern and indoor air conditions.

Installation is described as tool-free. Match the HE401, HE402, HE405 or HE400 model before ordering.

7. NXBHG HE401 Filter Replace for Shark: Best for a two-filter HE401 pack

NXBHG is the better choice for HE400-series owners who want 2 filters in one pack. It fits Shark HE400, HE401, HE402 and HE405 models and is compared with part number HE4FKPET.

The filter uses a pre-filter, efficient middle filter and activated carbon. NXBHG also gives the filter a MERV 13 rating, so buyers can compare its stated filtration details with the H13 True HEPA options in this roundup.

The package contains 2 filters, which gives you a spare after the first replacement. Each filter is listed at 17.3 x 3.5 x 15.3 in, so compare the size with the space inside your purifier before ordering.

NXBHG recommends changing the filter every 6 to 12 months. It installs without additional tools, and the maker lists a 30-day warranty.

Choose NXBHG when pack size matters most. Choose Leemone or FCFMY when a stated H13 True HEPA layer is more important to your decision.

8. BUXEBUX HP302 NeverChange Air Purifier Max Replacement: Best for HP302 and HC500 families

BUXEBUX is made for a broad group of Shark Max and Clean Sense models. Its compatibility list includes HP302, HP300, HP301, HP201, HP202, HP232, HC501, HC502, AP1000 and UA205.

The filter measures 12.04 x 8.66 x 1.61 in and uses an H13 True HEPA filter, activated carbon and a pre-filter. That combination suits households comparing particle filtration and odor reduction in one replacement.

Part numbers include HE3FKPET, HE2FKPRO, HE2FKBASMB, HE2FKBAS and HE2FKPET. Match both the model family and the part number because the compatibility list covers several Shark product lines.

The package includes 1 filter. BUXEBUX recommends replacement every 6 to 12 months, depending on use, and says the filter installs without tools.

Remove the new filter from its plastic bag before putting it into the purifier. Choose this model when your Shark unit belongs to the HP300, HP200 or HC500 families rather than the HP102 group.

9. Fette Filter HP102 Filter Replacement For Shark HP102: Best for broad HP100-series fit

Fette Filter is a broad-fit option for Shark HP100 and HP102 families. It fits HP100, HP100C, HP102, HP102C, HP105, HP130, HP132, HP152 and HP153 models, along with listed HC, UA and pet models.

The filter also matches HP102PET, HP102PETBL, HP102PETPR and HP102PK2. Its direct replacement part numbers are HE1FKPET, HE1FKBAS, HE1FKBASMB and HE1FKPRO.

Fette Filter lists fiberglass as the material and MERV 8 as the rating. It uses a cylindrical canister format, so compare your existing filter's shape and model before ordering.

The filter is designed for tool-free installation. Fette Filter states that each canister is built for 6 to 12 months of use, depending on the purifier and room conditions.

This is a useful choice when your purifier has one of the less common HP100-family or pet-model numbers. For HP102 owners who want 2 filters, the ShufudeJa pack ranks higher in this comparison.

How do you match a Shark air purifier filter to your model?

Match the purifier's model number, filter part number, shape and dimensions before comparing brands. Shark's HE400 family uses HE4FK parts, HP102-family units use HE1FK parts, and HP201-family units use HE2FK parts.

A model match is more useful than the Shark name alone. Check the label on the purifier, then compare it with the compatibility list for the replacement filter.

For example, the Leemone and FCFMY single-filter options fit HE400-series models. ShufudeJa and Fette Filter target HP102-family models, while iSingo and BUXEBUX cover HP200, HP300 and related Max units.

Round filters also need careful checking because HP102 and HP201 filters are not interchangeable. Diameter and height can differ even when both filters look cylindrical.

If you are still comparing purifier sizes for different rooms, review our guide to what are the best small air purifiers.

What should you check before replacing a Shark filter?

Check the exact model, replacement part number, filter shape, pack contents and replacement interval. Also confirm that the filter layers match your priority, such as a pre-filter for larger particles, HEPA filtration for fine particles or activated carbon for household odors.

Start with the label on your purifier, not the product title alone. Shark uses similar names across families, and a listing may mention several models that sound close to yours yet use a different size.

Write down the model and any part number shown on the old filter, then compare both against the compatibility list word for word.

A 1-filter pack may suit a single scheduled change, while a 2-pack gives you a spare. Leemone is different because its package includes 1 main HEPA filter and 2 replaceable pre-filters, which can suit homes where hair and dust load the outer layer faster than the main filter.

Pack size also affects storage and timing. A spare lets you change a worn filter without waiting for delivery, but it only helps if you will use it within a sensible period.

Check the replacement guidance on the pack and keep the spare sealed until you need it.

Look at the stated dimensions when the filter is not a standard match. The HP102-family filters here are about 7.56 in in diameter and 7.17 in high, while the HP201 replacement is 8.7 in in diameter and 11.9 in high.

Those gaps are large enough that a nearby size may still foul the housing or sit loose.

Shape deserves the same care as size. Rectangular HE400 filters slide into a different housing from round HP102 or HP201 canisters, and the two round formats are not interchangeable.

Confirm whether your unit takes a flat rectangular filter or a cylinder before you compare prices or layers.

Do not choose by the product name alone. Compare the exact model and part number, especially when a compatibility list covers several Shark families.

A broad list can be a plus, but it also raises the chance of a close but wrong match.

Consider your room and daily use next. Homes with pets, cooking odors or frequent dust may need the carbon layer and more frequent pre-filter checks.

Cleaner rooms may still need correct fit and timely change, even if the filter looks fine at a glance.

Care guidance is part of the check too. Note whether the maker advises 6 to 12 months, a shorter interval, or a separate schedule for a pre-filter.

That timing affects running cost and whether a larger pack makes sense for you.

How do you install and care for a Shark air purifier replacement filter?

Most products here describe tool-free replacement, but the general process is to turn off the purifier, remove the old filter, take the new filter out of its plastic bag and install it in the correct direction. Then reset the Filter Life system if your model uses that control.

Work in a clear space and keep the old filter for a quick size comparison before you discard it. Check that the new unit has no torn wrap, bent pleats or loose carbon layer, since damage in transit can affect fit or airflow.

Seat it fully so there is no gap for unfiltered air to bypass the filter.

Leemone, FCFMY and the HE601 replacement advise pressing and holding the Filter Life button for 3 seconds after installation. A beep indicates that the timing system has reset, so listen for it before you walk away.

If your model has no such button, follow the purifier manual rather than guessing at a reset step.

Replacement timing varies by product. Several recommendations fall between 6 and 12 months, while Pulluty gives a 3 to 6 month interval and Leemone recommends replacing its pre-filter every 3 months.

Treat those ranges as guidance tied to use, not as a promise that every home will get the same life from one filter.

Dust and indoor air conditions can shorten the useful interval. A purifier used around pets, cooking smoke or heavy household odors may need closer attention than one used in a cleaner room.

Glance at the pre-filter between changes and plan ahead when it looks loaded or smells stale.

Store spares sealed in a dry place away from direct heat. When the next change comes, remove the bag fully, install the filter promptly and reset the timing again so the alert matches the new filter, not the old one.

Which Shark replacement filter is best for smoke, pets or odors?

Choose a filter with activated carbon when household odors, cooking smells, smoke or pet odors are part of your reason for replacing the filter. HEPA and pre-filter layers address different parts of the filtration job, so compare the full layer design.

Leemone, FCFMY, iSingo and BUXEBUX all list activated carbon alongside HEPA or main-filter layers. NXBHG also lists activated carbon with a pre-filter and efficient middle filter.

For wildfire smoke, a compatible filter is only one part of the setup. Room size, purifier airflow and placement also matter.

Our guide to the best home air purifier for wildfire smoke covers that larger decision.

Do not skip model matching for a smoke-focused purchase. A filter with the right carbon layer still fails your needs if it does not fit the purifier.

Verdict: which Shark air purifier replacement filter should you buy?

Choose Leemone if you own a HE400-series purifier and want 2 replaceable pre-filters with the main HEPA filter. That set suits homes where the outer layer loads up sooner and you would rather refresh it on its own schedule.

Choose ShufudeJa for HP102-family owners who want 2 filters, or FCFMY for HE601 and HE602 models. The HE601 pack is a focused choice rather than a general Shark filter, so confirm those two model numbers before you treat it as an option.

Pick iSingo for HP201 or HP202, BUXEBUX for a wider HP200, HP300 or HC500 family fit, and NXBHG when a 2-filter HE400 pack matters most. Each pick answers a different need, from broad family coverage to a simple spare for the next change.

Do not let a higher score override fit. A filter that matches your model, part number, shape and size will do the job you bought it for, while a near match can leave gaps, jam the housing or fail to reset the timing system.

That check takes a minute and saves a return.

Match the layers to your home as well. Pre-filter and HEPA layers handle the particle side of the work, while activated carbon is the part aimed at household odors.

If odors are your main concern, a pack without carbon may not meet your goal even when the size is right.

Think about timing before you decide on pack size. A single filter is fine for one planned change, while a 2-pack helps when you want a spare ready to go.

Leemone follows a different rhythm again, with a pre-filter schedule that differs from the main filter schedule.

Always confirm the purifier model and replacement part number before ordering. Then keep the spare sealed, install it without tools where stated, and reset the Filter Life system when your model calls for it.

Frequently asked questions

How do I choose the right Shark air purifier replacement filter?

Match the exact Shark model and replacement part number first. HE400-series units use filters such as HE4FKPET, HP102-family units use HE1FK parts, and HP201-family units use HE2FK parts.

Check the purifier label before comparing filter layers, dimensions or pack size.

Are Shark air purifier filters interchangeable?

No. Shark filters are made for specific purifier families and sizes.

For example, the ShufudeJa HP102 filter is not compatible with HP201, HP202 or HC501, while the Leemone and FCFMY HE400 filters target different model groups.

Match the model before ordering.

How often should Shark air purifier filters be replaced?

Many filters here recommend replacement every 6 to 12 months, depending on air quality and use. Leemone recommends replacing its pre-filter every 3 months and its HEPA filter every 6 to 12 months.

Follow the purifier's Filter Life alert and inspect the filter regularly.

What is the difference between a Shark HE400 and HP102 filter?

HE400 filters are used in Shark's 4-fan models and are generally rectangular, while HP102 filters are round and fit a separate family of compact and related purifiers. The part numbers also differ: HE4FK for HE400 and HE1FK for HP102-family filters.

Can I use a compatible filter instead of a Shark-branded filter?

Yes, a compatible filter can work when its model list, part number and dimensions match your purifier. Check those details before ordering, then remove the filter from its plastic bag, install it as directed and reset the purifier's Filter Life system when required.
