The best Honeywell HPA100 replacement filters depend on whether you want a Honeywell-made main filter, a single replacement, or a set that also includes carbon pre-filters. Our top pick is the isinlive combo because it names HPA100 compatibility and includes both filter types.

The HPA100 uses a rectangular Filter R main filter. Some replacement kits also include carbon pre-filters, but those may be specified for HPA300 series models, so check compatibility for each part before ordering.

How we chose these Honeywell HPA100 replacement filters

We compared the stated compatible-model lists, pack contents, filter dimensions where available, and whether carbon pre-filters come with the main filter. The score weighs those details against what HPA100 owners are likely to need.

An HPA100 fit claim alone does not confirm that every piece in a multi-model kit fits the purifier. For a broader overview of best Honeywell HEPA filter replacement, compare model fit and whether you need only the main filter or a full set.

Best Honeywell HPA100 replacement filters for different needs

The isinlive set is the clearest all-in-one HPA100 choice, while Honeywell’s own Filter R is a direct brand option. The remaining picks offer larger packs or different combinations, with extra care needed for pre-filter compatibility.

1

isinlive HPA100 Filter Replacement for Honeywell Air: Best for a complete HPA100 set

9.7/10Our score

• Fits HPA100 and several related models
• 2 HEPA filters
• 8 precut carbon pre-filters

A complete set for buyers who want both main filters and precut carbon pre-filters in one pack. Check your purifier's model number against the compatibility list.

See it on Amazon

Pros

• Includes precut carbon filters
• Names HPA100 compatibility
• FSC-certified paper

Cons

• Third-party replacement

The isinlive set is our top pick because it specifically names HPA100 and includes both the main filters and precut carbon pre-filters. The package contains 2 HEPA filters and 8 carbon pre-filters, which makes it useful if you want to keep both parts on hand.

The compatibility list also includes HPA094, HPA101, HPA104, HPA105, HA106, HPA3100, HPA5100 and HPA5150. Match your purifier’s exact model before buying, especially if it belongs to a related series rather than the HPA100.

The filter material is described as H13 True HEPA and carbon. The brand also identifies FSC-certified paper and a 90-day warranty.

This is a third-party replacement, so choose it if the included carbon filters and named model fit matter more than sticking with Honeywell-branded filters.

2

Honeywell HEPA Air Purifier Filter R: Best for a Honeywell-made filter

9.6/10Our score

• Honeywell brand
• 3 filters
• Designed for HPA100 and other named series

The brand-made option is designed for HPA100 and other Honeywell purifier series. Its pre-filters are sold separately.

See it on Amazon

Pros

• Honeywell brand
• 3 filters per pack
• Names HPA100 compatibility

Cons

• Pre-filters are sold separately

Honeywell’s Filter R is the best fit if you want a filter made under the Honeywell brand. It is designed for HPA094, HPA100, HPA200, HPA250, HPA300 and several 3000, 5000 and 8000 series purifiers.

The pack has 3 filters, and the carbon pre-filters are sold separately. Honeywell says its HEPA filters help capture 99.97% of dust, pollen, pet dander, dust mite debris and smoke particles from air that passes through the filter.

Honeywell recommends replacing its HEPA filters once a year. This option keeps the main-filter choice straightforward, but remember to account for the separate pre-filter if you use one.

Blutoget 6 Pack HPA300 Filter R Replacement: Best for a large mixed-model set

9.5/10Our score

• 6 main filters
• 8 precut carbon pre-filters
• Names HPA100 compatibility

This larger set names HPA100 among its compatible models and includes both filter types. Its carbon pre-filters are custom-fit for HPA300, so verify fit for your HPA100 before buying.

See it on Amazon

Pros

• Large number of main filters
• Includes carbon pre-filters
• Names HPA100 compatibility

Cons

• Carbon pre-filters are described as HPA300-fit

Blutoget offers a large mixed-model set with 6 main filters and 8 precut carbon pre-filters. Its compatibility list names HPA100 along with HPA200, HPA300, HPA304 and other models.

The key detail is that Blutoget describes the carbon pre-filters as custom-fit for HPA300 series. That means HPA100 compatibility for the main filters should not be taken as confirmation that the carbon pieces fit your purifier.

Blutoget recommends replacing the main filter every 6–12 months and the carbon pre-filter every 2–3 months, depending on use and environment. The set may suit households with multiple compatible Honeywell models, provided each part matches the machine it will serve.

If you’re comparing the larger purifier’s options, our best Honeywell HPA300 replacement filters guide focuses on those kits.

4

PETOX HPA300 Filter Replacement for Honeywell Air: Best for a mixed HPA series household

9.2/10Our score

• 6 main filters
• 8 carbon pre-filters
• Names HPA100 compatibility

PETOX names HPA100 among the compatible models for its main filter. The carbon pre-filters are specified for HPA300 series, so confirm whether that part fits your purifier.

See it on Amazon

Pros

• Names HPA100 compatibility
• Includes 6 main filters
• Includes carbon pre-filters

Cons

• Carbon pre-filters are specified for HPA300 series

PETOX also names HPA100 compatibility for its main filter set. It includes 6 main filters and 8 carbon pre-filters, with the carbon pieces specified for HPA300 series purifiers.

That split matters if you own an HPA100. The main filter compatibility list includes HPA100, but the pre-filter fit list is narrower, so confirm whether those carbon parts match your unit before choosing the bundle.

PETOX recommends replacing the main filter every 6–12 months and the pre-filter every 2–3 months, depending on use and environment. Its description identifies the main filter as non-woven fabric and activated carbon as the pre-filter material.

5

LANTINY HPA300 HEPA Filter R Replacement: Best for a six-filter pack

9.0/10Our score

• 6 HEPA filters
• Names HPA100 compatibility
• No carbon pre-filters included

This six-pack names HPA100 compatibility and contains main filters only. Buy carbon pre-filters separately if your replacement routine calls for them.

See it on Amazon

Pros

• Six filters in the pack
• Names HPA100 compatibility
• Dimensions are provided

Cons

• No carbon pre-filters included

LANTINY provides 6 main filters and names HPA100, HPA200, HPA300, HPA304 and selected other models as compatible. The pack does not include carbon pre-filters, so it works best for buyers who only need the main filter.

The stated filter dimensions are 10.24 x 6.5 x 1.6 inches. LANTINY recommends a 6–12 month replacement interval for the main filter.

Its title focuses on HPA300, but the compatibility information also names HPA100. Check the model number and dimensions against the filter you are replacing, and buy a separate carbon pre-filter if needed.

6

Filter Bros HRF-R1 HEPA Replacement Filter R: Best for one replacement filter

8.8/10Our score

• One filter
• Fits HPA100 series
• Carbon pre-filter sold separately

A single-filter option suits buyers replacing one filter at a time. Filter Bros says its carbon pre-filters are sold separately.

See it on Amazon

Pros

• Single-filter pack
• Names HPA100 compatibility
• Provides filter dimensions

Cons

• Carbon pre-filter sold separately

Filter Bros sells a single HRF-R1 filter, which is useful if you need one replacement instead of a multi-pack. Its compatibility list includes HPA-100 and related HPA series models.

The filter measures 10.25 x 6.5 x 1.5 inches. Filter Bros recommends replacing its HEPA filter annually and says activated charcoal pre-filters are sold separately.

This pick keeps the purchase focused on one main filter. Filter Bros notes that its replacement may not fit exactly like the previous filter, so check the dimensions and confirm the fit if a precise match is important.

7

Laukowind HPA304 Filters Replacement for Honeywell Home: Best for a smaller mixed pack

8.5/10Our score

• 3 main filters
• 6 precut carbon pre-filters
• Names HPA100 compatibility

This smaller combo pack names HPA100 as compatible and includes precut carbon pre-filters. The pre-filter shape is described for HPA300, so check fit for your model.

See it on Amazon

Pros

• Includes main filters and carbon pre-filters
• Names HPA100 compatibility
• Pre-filters come precut

Cons

• Pre-filter fit is described for HPA300

Laukowind’s pack contains 3 main filters and 6 precut carbon pre-filters, and its compatibility list names HPA100. It is a smaller combo than the six-filter kits.

The maker describes the carbon pre-filters as precut for HPA300, though they can also be cut to fit other models. For HPA100, check the size and shape before relying on the included carbon pieces.

Laukowind recommends replacing the main filter every 6–12 months and the carbon filter every 2–3 months. The pack may suit buyers who want a modest supply and are comfortable checking pre-filter fit separately.

8

Cabiclean 9 Pack HPA300 HEPA Filter Replacement: Best for a main-filter stock-up

8.2/10Our score

• 9 main filters
• Names HPA100 compatibility
• No carbon pre-filters included

The nine-filter pack names HPA100 compatibility and focuses on main filters. Carbon pre-filters are not included.

See it on Amazon

Pros

• Nine main filters
• Names HPA100 compatibility
• Provides filter dimensions

Cons

• No carbon pre-filters included

Cabiclean’s 9-pack contains main filters only and names HPA100, HPA200 and HPA300 series models as compatible. It is a stock-up option if you already have a separate source for carbon pre-filters.

The stated dimensions are 10.2 x 6.5 x 1.6 inches, and Cabiclean recommends replacing the main filter every 6–12 months, depending on use and environment. The compatibility list includes several related models, such as HPA094, HPA101, HPA104, HPA105 and HA106.

Choose it for a larger supply of main filters, but make sure the pack and your separate pre-filter plan match your purifier.

How do you choose an HPA100 filter replacement?

Start with the full model number on your purifier, then confirm that the replacement explicitly includes it. A broad HPA-series compatibility claim can cover multiple main-filter models while leaving the carbon pre-filter fit limited to a different series.

Next, decide whether you need the main filter only or a combo pack. Honeywell’s Filter R and the LANTINY, Filter Bros and Cabiclean options focus on main filters, while isinlive, Blutoget, PETOX and Laukowind include carbon pre-filters.

Compare pack quantity with how often the brand recommends replacement. A large pack can be useful if you have storage space and expect to use the same filter type, while a one-filter pack can avoid keeping extras.

Do HPA100 filters include carbon pre-filters?

Some HPA100 replacement sets include carbon pre-filters, but several multi-model kits describe those pre-filters as HPA300-fit. The main filter and pre-filter should be checked as separate parts.

The isinlive set names HPA100 and includes 8 precut carbon pre-filters. For Blutoget, PETOX and Laukowind, confirm the carbon pieces fit your HPA100 before buying; their descriptions specifically call out HPA300 series fit.

A carbon layer is generally used as a pre-filter alongside the main filter. Learn what an electrostatic filter does if you want to understand how some filter materials capture particles.

What should you check before ordering?

Check the model label on the purifier, the replacement filter’s compatibility list, and the stated dimensions. If you are buying a combo kit, confirm that both the main filter and carbon pre-filter fit your specific model.

Replacement schedules vary by brand and use. Honeywell recommends replacing its HEPA filter once a year, while several compatible-filter brands recommend 6–12 months for the main filter and 2–3 months for carbon pre-filters.

If you’re researching another purifier system, our guide to IQAir HealthPro Plus replacement filters explains how its staged filter replacements differ.

Which Honeywell HPA100 replacement filter should you choose?

Choose isinlive if you want a set that names HPA100 and includes both main and carbon filters. Choose Honeywell’s Filter R if you prefer the brand-made main filter, or Filter Bros if you need one filter at a time.

For larger packs, LANTINY and Cabiclean focus on main filters, while Blutoget, PETOX and Laukowind add carbon pre-filters that need a separate fit check for HPA100. Match each part to your purifier model before ordering.

Frequently asked questions

Which filter fits the Honeywell HPA100?

Check that the replacement names HPA100 or HRF-R1 compatibility, then compare the full model number on your purifier. Several picks here also name HPA200 or HPA300 series, but carbon pre-filter fit can differ from main-filter fit.

For a brand-made option, Honeywell’s Filter R names HPA100 compatibility.

Does the HPA100 need a carbon pre-filter?

The picks with combo packs include carbon pre-filters, while the Honeywell Filter R, LANTINY, Filter Bros and Cabiclean options focus on main filters or sell pre-filters separately.

Check your purifier’s instructions for the correct replacement parts and schedule. Combo sets aimed at HPA300 may have pre-filters that need a separate fit check for HPA100.

How often should you replace an HPA100 filter?

Replacement timing depends on the filter and your use. Honeywell recommends replacing its HEPA filter once a year, while some compatible brands recommend 6–12 months for the main filter and 2–3 months for the carbon pre-filter.

Follow the directions for the filter you choose and your purifier.

Can an HPA300 filter fit an HPA100?

Some HPA300 replacement sets name HPA100 in their compatible-model lists, but that does not mean every part in the set fits both purifiers. PETOX, Blutoget and Laukowind describe their carbon pre-filters as HPA300-fit.

Check main-filter and pre-filter compatibility separately before ordering.
