Replacing the filter in a Febreze air purifier is a small chore that makes a real difference to how the machine performs. A clogged filter slows airflow and stops trapping dust, pet dander and odors effectively, and a filter that is the wrong shape will not seat properly at all. The good news is that Febreze purifiers use a small number of filter types, so the job is mostly about reading your model number and matching it. The label is usually on the bottom or back of the unit, and the purifier name will begin with FHT followed by three digits.
According to the listings, the options here sort by model. The FHT170, FHT180 and FHT190 family use the FRF102B filter, and two products cover it: a single replacement filter and a four-pack. The compact OdorGrab FHT150W uses a different small filter, sold here as a four-pack that references part FRF105. The fourth product is a genuine Febreze Linen & Sky scent refill cartridge, which works alongside a filter rather than replacing one. It is important to know that all three filters are compatible third-party products, not Febreze-branded parts; only the scent cartridge is made by Febreze.

The Models in Detail
FRF102B Filter Replacement for Febreze Air Purifier FHT170 FHT180 FHT190 Fit for Febreze air purifier filter replacement premium HEPA air filter
Check price on Amazon 4.0 out of 5 — average from Amazon buyers
Best for: FHT170, FHT180 and FHT190 owners needing one
Pros
- Replaces FRF102B filter
- Built-in carbon pre-filter
- 90-day assurance
Cons
- Third-party, not Febreze-made
- Single filter only
The FRF102B Filter Replacement for Febreze Air Purifier is a single third-party filter that replaces part FRF102B. The listing names the Febreze FHT170W, FHT180W and FHT190W as compatible, and also says it replaces the Honeywell HRF201B U filter used in the HHT270 and HHT290 tabletop and tower models, which share the same filter shape.
It is described as a dual action HEPA-type filter with a built-in carbon pre-filter for odor reduction, capturing up to 99.97% of particles down to 0.3 microns. It is rectangular and pleated, slides into place, weighs 16 ounces and is made with FSC-certified paper. The seller recommends replacing it every four months and offers a 90-day assurance for questions or problems.
One point to be careful with: the listing uses the term HEPA-type, which is not the same as a certified True HEPA filter. The 99.97% figure is the seller’s claim. Still, for an owner of an FHT170, FHT180 or FHT190 who needs a single filter now, it is the straightforward choice. The listing’s claim that it fits all Febreze HEPA-type purifiers is broader than its model list, so rely on the named models.
If you use your purifier constantly, especially in a room with pets, the four-pack below is more practical, since you will go through a filter every few months.
4 Pack Febreze Filter Replacement for FRF102B Experience easy installation with just three simple steps
Check price on Amazon 4.9 out of 5 — average from Amazon buyers
Best for: Stocking up a year of FRF102B filters
Pros
- Four filters per pack
- Wide FHT170 to FHT190 fit list
- Exact filter dimensions listed
Cons
- Third-party, not Febreze-made
- Spec dimensions contradict features
The 4 Pack Febreze Filter Replacement for FRF102B is another third-party option for the same purifier family, but it names more model variants: FHT170W, FHT170WCV, FHT180W, FHT180X, FHT1180V, FHT190V and FHT190W, plus Honeywell HHT270, HHT270W and HHT290 series units. The pack includes four double-acting filters.
The filters combine a high-efficiency activated carbon layer with what the listing calls a class true filter, and the spec block lists a MERV 13 rating. Installation takes three steps: turn off the purifier, open the filter door, swap the filter and close the door. The seller suggests replacing every two to four months, more often in polluted environments or with heavy use.
The listing gives the filter size as 10.04 inches high by 4.91 inches long by 1.38 inches wide, and the package as 10.2 x 5.1 x 6.1 inches. The spec block’s 1 x 1 x 1 inch dimensions are clearly placeholders. Compare the stated filter size with your old filter before installing.
At four filters, this pack covers roughly a year of use at the upper end of the suggested interval. It suits a household that runs its FRF102B purifier daily in a bedroom or home office and would rather not reorder every few months.
4 Pack FHT150W Replacement Filter for Febreze OdorGrab 4 Pack FHT150W Replacement Filter
Check price on Amazon 4.6 out of 5 — average from Amazon buyers
Best for: OdorGrab FHT150W owners
Pros
- Fits FHT150W, FRF105 part
- H13 filter with activated carbon
- Four filters per pack
Cons
- Third-party, not Febreze-made
- Fits only the FHT150W
The 4 Pack FHT150W Replacement Filter is made for the Febreze OdorGrab FHT150W portable air purifier and references part FRF105. This is a much smaller filter, listed at 3.74 x 3.74 x 0.63 inches, so it will not fit the FHT170-190 family, and the FRF102B filters above will not fit the FHT150W.
Each filter contains what the listing calls an H13 true filter along with activated carbon. The spec block lists a MERV 16 rating. The seller advises removing the plastic wrapping before installation, storing spares in a dry place and replacing a filter every three to six months. Four filters come in the pack, and the listing names the manufacturer separately from the seller brand.
The OdorGrab is a small purifier designed for spaces like bathrooms, closets or a litter box corner, where odor control is the priority. If that describes your unit, this is the only matching filter in this group. Confirm your model label says FHT150W before ordering.
Febreze Linen & Sky Air Purifier Scent Refill Cartridge Febreze Air Purifiers help capture airborne particles such as dust, pet
Check price on Amazon 4.0 out of 5 — average from Amazon buyers
Best for: Adding fresh scent to FRF102 purifiers
Pros
- Genuine Febreze scent cartridge
- Two-pack of Linen & Sky
- Monthly replacement is simple
Cons
- Not a filter
- Compatible models not listed
The Febreze Linen & Sky Air Purifier Scent Refill Cartridge two-pack is the only genuine Febreze product in this group, with model number FRF102L. It is not a filter. The description explains that the scent cartridge works with the air purifier filter, sold separately, to remove odors while circulating a clean Febreze scent. Each cartridge measures 1.43 x 4.02 x 0.47 inches.
Febreze recommends changing the scent cartridge every 30 days, so a two-pack covers about two months. The description also states that Febreze recommends genuine Febreze filters and scent cartridges, and that compatible replacements are not certified to offer the same performance or efficiency. That is worth weighing when choosing the third-party filters above.
The listing does not name which purifier models accept the cartridge, though the FRF102L model number suggests it is designed around the FRF102 filter family. It suits a household that likes a light fragrance in a living room or entryway. If anyone in the home is sensitive to scents, you can skip it; the filter does the actual air cleaning. For more on genuine refills, see our guide to Febreze air purifier filters and refills.

Before You Buy
None of the filter listings are genuine Febreze parts, and none give a standard warranty; the single FRF102B filter offers a 90-day assurance from the seller. Terms such as HEPA-type, class true filter and H13 are the sellers’ own descriptions, and the MERV ratings come from their spec blocks, not independent testing described in the listings. Febreze’s own scent cartridge listing notes that compatible filters are not certified to match genuine performance.
Replacement intervals vary from two to six months across listings, so use the filter’s color and your purifier’s performance as a guide as well. The scent cartridge listing does not say which purifiers accept it. If you also own other brands of purifier, our air purifier filter replacement guide covers a different filter system.
