The best air purifier replacement filters are the ones that match your purifier’s exact model and filter code. Our top pick is the genuine Levoit LV-H132 filter for owners of that series; the other choices cover specific Levoit, Blueair, Honeywell, GermGuardian, Holmes and Bionaire models.

A replacement can look close to the old one and still fail to fit. Check the complete purifier model number, filter code, shape and any required pre-filter before you order.

How we chose replacement filters for air purifiers

We compared the stated model compatibility, filter construction and pack contents for each option. Our score weighs those details against the needs of someone shopping for an air purifier replacement filter, with a higher score for clear model fit and useful details.

The products below serve different purifiers, so the order is a comparison of the match information and features provided, not a claim that one filter fits most machines. Start with your model number, then choose the option that names it.

For a model-specific Winix example, compare Winix 5500-2 replacement filters.

Compare the best air purifier replacement filters

Model fit is the main difference among these options, while the number and type of included filters vary by set. For a model-specific example, compare Coway AP-1512HH replacement filters.

Use the table to narrow the choices, then check your purifier label and manual before buying.

Best replacement filters for air purifiers by model

The best choice depends on the purifier you own, because these filters are not universal. Each pick below names specific compatible models or series, so treat the model match as the first buying check.

For another brand's model-by-model options, see Coway replacement filters.

Levoit LV-H132 Air Purifier Replacement Filter: Best for LV-H132 owners

9.7/10Our score

• Made for LV-H132 Series
• Pre-filter, main filter and activated carbon
• Levoit recommends replacement every 6 months

This genuine Levoit filter is designed for the LV-H132 Series and combines a pre-filter, main filter and activated carbon layer. It suits buyers who want the brand’s specified replacement for that model.

See it on Amazon

Pros

• Made for the LV-H132 Series
• Includes activated carbon
• Levoit recommends a 6-month replacement interval

Cons

• Single filter pack
• Compatibility is limited to the LV-H132 Series

The genuine Levoit replacement is made for the LV-H132 Series. Its three-stage setup includes a pre-filter for larger particles, a main filter and activated carbon for gases and odors.

Levoit recommends replacing it every 6 months and says the LV-H132 filter-life indicator and built-in algorithm work with authentic filters. If you rely on that indicator, this model-specific genuine option is a direct match for the series.

The filter comes as a single pack. Remove its plastic packaging before installing it, and make sure the purifier label says LV-H132 before ordering.

Choose this for an LV-H132 when you want the brand’s own replacement with carbon included. For a broader look at best HEPA replacement filters, compare other model-specific options.

2

Levoit Core 300-P Air Purifier Replacement Filter: Best for Core 300-P owners

9.6/10Our score

• Made for Core 300-P and Core 300S-P
• Pre-filter, main filter and activated carbon
• Levoit recommends replacement every 6 to 8 months

This genuine Levoit filter is designed for Core 300-P and Core 300S-P purifiers. It is the clearest match for owners seeking a model-specific replacement from the purifier brand.

See it on Amazon

Pros

• Explicit compatibility with 2 Core models
• Three filtration stages
• Levoit gives a 6 to 8 month interval

Cons

• Designed for the Core 300-P series only
• One filter per pack

The genuine Levoit Core 300-P replacement is designed for Core 300-P and Core 300S-P purifiers. It combines a pre-filter, main filter and activated carbon, with Levoit recommending a 6 to 8 month replacement interval.

Levoit says the filter achieves HEPA-grade filtration efficiency in Sleep Mode when tested with IEST RP C001.7 by an independent lab. The maker also offers versions aimed at different needs, including smoke, toxins and pet odors.

Check whether your purifier is a Core 300-P or Core 300S-P, since a similar Core name does not confirm fit. This is a sensible brand-matched option if you want the specified filter for either named model.

3

BLUEAIR Genuine 211+ Air Purifier Replacement Filter: Best for Blue Pure 211+

9.5/10Our score

• Authentic 211+ filter
• Particle filter with carbon mesh
• For Blue Pure 211+ non-auto models

Blueair identifies this as an authentic replacement for the non-auto Blue Pure 211+. Its particle filter includes a carbon mesh, so check your purifier version before buying.

See it on Amazon

Pros

• Brand-specific 211+ fit
• Carbon mesh included
• Dimensions are provided

Cons

• Compatibility excludes auto models
• Confirm the exact purifier version

Blueair identifies this as an authentic Blue Pure 211+ replacement for non-auto models. It includes one particle filter with carbon mesh, so the purifier version matters before purchase.

The filter measures 20.35 x 11.69 x 2.76 inches. Compare that against your old filter and purifier manual if the model label is unclear.

Choose it when your unit is the standard 211+ and you want a Blueair-branded filter with carbon mesh. Do not assume the same fit for an auto version based on the shared 211+ name.

4

Smilyan HPA300 HEPA Filter Replacement for Honeywell: Best for Honeywell HPA series

9.4/10Our score

• Claims compatibility with listed Honeywell HPA models
• 6 HEPA R filters and 8 carbon pre-filters
• Rectangular slide-in filters

This Smilyan set pairs 6 HEPA R filters with 8 activated carbon pre-filters. Its stated fit spans selected Honeywell HPA models, so compare the exact model and filter code before ordering.

See it on Amazon

Pros

• Multiple HEPA and carbon pre-filters
• Names several compatible HPA models
• Dimensions are provided

Cons

• Compatibility list needs a model-by-model check
• Pack contains 2 different filter types

Smilyan’s set is aimed at selected Honeywell HPA models, including HPA100, HPA200, HPA300 and several related series models. It contains 6 HEPA R filters and 8 activated carbon pre-filters, with stated R-filter dimensions of 10.2 x 6.5 x 1.6 inches.

The compatibility information includes filter codes HRF-R3, HRF-R2 and HRF-R1, plus a separate statement that the carbon pre-filters fit the HPA300 series. Match both the purifier model and filter code, especially if your Honeywell is not an HPA300.

This bulk set can suit a household that wants several routine replacements ready. The included filters are different types, so confirm how many of each your purifier uses.

5

Cabiclean Core Mini Replacement Filter for LEVOIT: Best for Core Mini replacements

9.3/10Our score

• For Core Mini and Core Mini-P
• Pre-filter, personal filter and activated carbon
• 2 filters and 10 aroma pads

Cabiclean says these filters fit the Levoit Core Mini and Core Mini-P, and the package includes 2 filters plus 10 aroma pads. Check the model carefully because the maker limits compatibility to those Mini versions.

See it on Amazon

Pros

• Two replacement filters
• Aroma pads included
• Compatibility is stated for 2 Mini models

Cons

• Not intended for other Levoit models
• Aroma pads may not matter to every buyer

Cabiclean says this replacement fits Levoit Core Mini and Core Mini-P purifiers. The 3-in-1 filter combines a pre-filter, personal filter and activated carbon, and the package includes 2 filters and 10 aroma pads.

Its model restriction is important: this is not a general Core-series filter. Check the label for Core Mini or Core Mini-P, and compare the old part number if you have it.

Choose this two-pack if those aroma pads are useful and the model match is exact. Owners of other Levoit Core models should use a filter named for their specific machine instead.

6

Colorfullife Core 200S Replacement Filter Compatible: Best for Core 200S two-packs

9.2/10Our score

• Compatible with Core 200S and Core 200S-P
• H13-grade filter with nylon pre-filter and activated carbon
• 2 filters per pack

This compatible Colorfullife two-pack is designed for the Levoit Core 200S and Core 200S-P. It combines three filter layers, but the maker says it does not fit the Vista 200.

See it on Amazon

Pros

• Two filters per pack
• Three filtration layers
• Compatible models are named

Cons

• Not for Vista 200
• Compatible replacement rather than a Levoit-branded filter

This compatible Colorfullife filter is designed for the Levoit Core 200S and Core 200S-P, not the Vista 200. Each filter has a nylon pre-filter, H13-grade filter and activated carbon layer, and the pack contains 2 filters.

The maker recommends changing filters every 3 months, while also saying replacement timing depends on use and air quality. Compare that guidance with the instructions for your purifier before setting a schedule.

This can suit a Core 200S owner who wants a two-pack of compatible filters. It is not a Levoit-branded replacement, so buyers who prefer genuine parts may want to choose a brand-made filter for their model.

7

isinlive Vital 200S Pet Care Replacement Filter: Best for Vital 200S pet care

9.1/10Our score

• Compatible with Vital 200S and Vital 200S-P
• Main filter and activated carbon layer
• 2 filters per pack

isinlive names the Levoit Vital 200S and 200S-P as compatible models. The two-pack is positioned for pet care and includes an activated carbon layer; confirm your purifier’s exact model code.

See it on Amazon

Pros

• Two filters included
• Made for named Vital 200S models
• Activated carbon layer

Cons

• Exact fit should be checked before ordering
• The product name emphasizes pet care

isinlive names the Levoit Vital 200S and Vital 200S-P as compatible models for this two-pack. The filter combines a main filter with an activated carbon layer, and the maker positions it for pet care.

The product description mentions pet dander, lint, odors and smoke as targets for the filter. It also describes an activated carbon formula, but your main check should remain the Vital 200S model match.

Choose this when you have a named Vital 200S model and want two compatible replacements with carbon. Confirm the filter part number in your manual if your purifier has a similar model name.

8

isinlive FLT4825 HEPA Filter B Replacement: Best for GermGuardian FLT4825

9.0/10Our score

• Compatible with listed Guardian, PureGuardian and Black+Decker models
• 4 HEPA filters and 8 carbon pre-filters
• Designed for routine replacement

This isinlive set includes 4 Filter B replacements and 8 activated carbon pre-filters. It names several GermGuardian models plus select PureGuardian and Black+Decker units, so use the model list as a fit check.

See it on Amazon

Pros

• Multiple filters in one set
• Compatible model list includes AC4825E
• Carbon pre-filters included

Cons

• Several brands and models require careful matching
• The package combines 2 filter types

This isinlive set includes 4 FLT4825 Filter B replacements and 8 activated carbon pre-filters. Its compatibility list covers several GermGuardian models, including AC4825E, along with select PureGuardian and Black+Decker units.

The stated dimensions are 15.7 x 4.7 x 0.6 inches. Check the full purifier model and Filter B code, since the set spans several product families and a similar model number may use another filter.

For a narrower GermGuardian-specific comparison, see our guide to the GermGuardian AC4825E filter. This multi-filter pack may suit regular maintenance when the exact fit is confirmed.

9

Colorfullife 4 True HEPA + 8 Pre-Filter: Best for Holmes and Bionaire

8.3/10Our score

• 4 True HEPA filters and 8 carbon booster pre-filters
• Names Holmes and Bionaire models
• Replaces A, D and K filters

This Colorfullife set combines 4 True HEPA filters with 8 carbon booster pre-filters for selected Holmes and Bionaire purifiers. Check your model number against the long compatibility list before choosing it.

See it on Amazon

Pros

• Several filters in one pack
• Names compatible Holmes and Bionaire models
• Carbon booster pre-filters included

Cons

• Long model list takes careful checking
• Does not cover every purifier from either brand

Colorfullife’s Holmes and Bionaire set contains 4 True HEPA filters and 8 carbon booster pre-filters. It names a range of compatible models and says the filters replace A, D and K filter types.

The model list is long, so compare the full purifier number rather than relying on the brand alone. The product information also identifies compatibility with selected Bionaire units and many Holmes units.

Choose it only after checking your model against the named list and confirming the filter type in your manual. The included carbon boosters are intended to help with household odors and larger contaminants such as hair and lint.

How to match a replacement filter to your purifier

Match the purifier’s full model number and filter code before comparing brands or pack sizes. A filter advertised for a related series may not fit every model in that family.

Check these details:

• Purifier model: Find the full code on the unit label or in the manual.
• Filter code: Compare the old filter’s code with the replacement’s stated fit.
• Shape and dimensions: Use these as a second check, not a substitute for model compatibility.
• Filter layers: Look for the combination your purifier uses, such as a main filter plus a carbon pre-filter.
• Replacement schedule: Follow your purifier’s instructions and account for the filter maker’s guidance.

If you are unsure where the model label is or how to identify the filter, our 3-step guide to testing a HEPA filter at home can help with the inspection process. A simple visual check cannot confirm every performance claim, so use the manual and model codes as your fit guide.

Do HEPA and carbon filters do the same job?

HEPA-style media and activated carbon address different things, so check which layers your purifier needs. A particle filter is designed for airborne particles, while carbon is used to help reduce gases and odors.

Some replacement sets combine a main filter with a carbon layer or separate carbon pre-filters. For Levoit-specific care, see whether Levoit filters are washable.

The Levoit, Colorfullife and isinlive examples above describe multi-layer options, while the Blueair 211+ filter includes carbon mesh.

Filter labels such as “H13” or “HEPA-grade” do not tell you whether the filter fits your machine. For a closer look at the particle-filter role, read how a HEPA filter works inside a purifier.

Should you choose a genuine or compatible filter?

A genuine filter is made by the purifier brand for its stated models, while a compatible filter is made by another brand and claims a fit for named models. Your choice can depend on model match, filter-life features, included layers and whether you want the purifier brand’s part.

Levoit says its LV-H132 and Core 300-P filter-life indicators and algorithms work with authentic filters. For compatible options, compare the exact model list, part number and physical dimensions with your manual.

For example, the Levoit choices here are branded replacements, while the Colorfullife Core 200S, Cabiclean Core Mini and isinlive sets are compatible alternatives. Read the fit limits carefully before deciding.

Can you wash an air purifier replacement filter?

Only wash a filter if its instructions say it is washable. Many HEPA replacement filters are designed for replacement, and washing can harm the media or change how it works.

Check the manual for the main filter and any reusable pre-filter separately. Our guides explain whether air purifier filters are washable and whether you can wash a HEPA filter.

How to choose the best air purifier replacement filters

The best air purifier replacement filter is the one that matches your exact model and provides the layers your purifier is designed to use. Pick the genuine Levoit LV-H132 or Core 300-P filter for those models, the Blueair filter for a non-auto 211+, and a compatible multi-pack only after checking its model list.

If HEPA filtration is your main concern, compare our best HEPA replacement filters guide next. For model-specific choices, see the best replacement filters for Kenmore air purifiers or the best replacement filters for Mooka air purifiers.

Remember to check the purifier’s model label, old filter code and manual before ordering. That simple match is more useful than choosing by brand name alone.

Frequently asked questions

How do I find the right replacement filter for my air purifier?

Check the purifier’s full model number and the filter code in its manual or on the old filter. Match both against the replacement’s stated compatibility, since similar names can refer to different sizes or generations.

If a brand offers a genuine replacement, compare that option with compatible filters only after confirming the fit.

Are compatible air purifier filters as good as genuine filters?

That depends on the specific filter and purifier. A compatible filter may fit a named model and offer similar filter layers, while a genuine filter is made by the purifier brand for its stated models.

Check fit, construction, replacement guidance and any filter-life indicator requirements before deciding.

How often should I replace an air purifier filter?

Follow the purifier manual and filter maker’s schedule, then adjust for use and room conditions if the instructions allow. The Levoit LV-H132 filter recommends 6 months, while the Core 300-P filter recommends 6 to 8 months.

A filter that looks dusty may still need the manual’s replacement guidance.

Can I wash a HEPA air purifier filter?

Only wash a filter if its instructions say it is washable. Many HEPA-style replacement filters are designed to be replaced, and water can damage filter media or reduce its intended performance.

See our guide on whether air purifier filters are washable and check your purifier manual before cleaning.
