TL;DR: Appliancemates' HEPA‑13 filter captures 99.97% of particles ≥ 0.3 µm, fits Honeywell HPA300 units, and comes in a nine‑filter pack for $29.88, earning a solid 4.6‑star rating.

The standout spec is its 99.97 percent filtration efficiency at a minimum particle size of 0.3 microns, meeting HEPA 13 and MERV 17 standards. Its physical size—6.5 × 1.6 × 10.2 in (40.64 mm × 165.1 mm × 259.08 mm)—matches the original Honeywell dimensions, so installation is straightforward. The package supplies nine filters (three HEPA R filters and six carbon pre‑filters), giving you plenty of spares for a full year of use.

Compared with other options in this roundup, the Appliancemates filter is longer than the Honeywell HRFSS1 (259.08 mm vs 175.26 mm) but shares the same width (165.1 mm) and height range. Its dimensions are essentially identical to the Funmit HPA200 filter, which also lists a 259.1 mm height and 165.1 mm width. While its $29.88 price places it in the premium tier, the rating of 4.6 stars is a shade below the top‑rated Honeywell HRF‑H1’s 4.8‑star score.

Users appreciate the filter’s high capture rate and the added activated carbon layer that tackles odors, dust, pollen, and other allergens. The 4.6‑star average from 1,742 reviews reflects consistent satisfaction, especially for households needing reliable allergy relief. A recurring comment mentions the convenience of the nine‑filter pack, though some note that the carbon pre‑filter should be swapped every three months, adding a modest maintenance step.

Technically, the filter is non‑washable and is designed for a 12‑month replacement interval for the HEPA element, while the carbon pre‑filter is recommended every three months. It targets common indoor pollutants such as dust, pollen, and allergens, making it a solid choice for allergy‑prone environments.

Best for: Buyers willing to invest in a proven, high-quality option — the Appliancemates HPA300 Replacement Filter offers Height: 40.64 mm

TL;DR: The Funmit HPA200 Filter packs a two‑stage HEPA and activated‑carbon system with a 5.1 mm carbon depth and a 40.6 mm HEPA depth, delivering solid performance for large‑room Honeywell units at $25.99.

What really sets this filter apart is its dual‑stage construction: a 5.1 mm activated‑carbon pre‑filter sits in front of a 40.6 mm electrostatic electret HEPA filter. The combination targets both particles and odors, and the filter’s dimensions (carbon height 350.5 mm, HEPA height 259.1 mm) fit the Honeywell HPA100/200/300 series without modification.

Compared with the other ten contenders, the Funmit sits on the heavier side at 1.52 lb, while the Honeywell HRF‑H1 weighs only about 0.4 lb. It also offers a full two‑stage design, whereas some rivals list only a HEPA core or omit the carbon layer entirely. The package includes six filters (two HEPA and four pre‑cut carbon), giving you more replacements than many single‑unit kits.

Customers rate the filter 4.6 / 5 from 704 reviews, noting the tool‑free installation and noticeable odor reduction as highlights. Reviewers also appreciate the 6‑12 month replacement interval, which reduces the hassle of frequent swaps.

TL;DR: The Honeywell HRF‑H1 delivers True HEPA filtration (99.97% at 0.3 µm), fits compactly in Honeywell tower units, and costs $25.99 while weighing just 0.4 lb.

The standout spec is its True HEPA rating with 99.97 percent filtration efficiency down to 0.3 microns, meeting the same standard used in medical settings. At only 0.4 lb (181 g) and a compact footprint of 1.65 × 4.84 × 10.12 in, the filter is easy to handle and fits neatly into the listed Honeywell models (HPA‑050, HPA‑060, HPA‑061, HHT‑055, HPA‑150, HPA‑160, HHT‑155). The manufacturer recommends swapping it out once a year, which many users find aligns well with their maintenance schedule.

Compared with other filters in this roundup, the HRF‑H1 is markedly lighter than the Funmit HPA200 (1.52 lb) and far lighter than the Appliancemates HPA200 (3.00 lb). Its dimensions are also smaller than the Isinlive replacement (which lists a larger HEPA filter height of 40.64 mm and length of 259.08 mm), making it a good fit for tighter spaces. The Honeywell HRF‑C1 sits at a similar weight of 0.41 lb, but the HRF‑H1 omits a carbon pre‑filter, so it focuses purely on particle capture.

Reviewers consistently praise the filter’s ability to trap pollen, pet dander, dust, smoke, mold spores and dust‑mite debris, noting the “99.97 percent” capture rate as a major selling point. A common complaint is that larger compatible units require two HRF‑H1 filters, which doubles the material cost for those setups. Some users also mention that third‑party replacements aren’t guaranteed to meet the same standards, so sticking with the OEM part feels safer.

Beyond the HEPA media, the filter supports an air‑change rate of 4.8 ACH, meaning the air in a typical room is refreshed roughly five times per hour when paired with a compatible purifier. This aligns with the performance expectations for allergy‑prone households and small office spaces.

Best for: Buyers willing to invest in a proven, high‑quality option — the Honeywell HRF‑H1 offers Depth: 257 mm and a compact 1.65 × 4.84 × 10.12 in footprint.

Avoid if: You're on a tight budget or only need basic functionality without the premium HEPA performance.

TL;DR: The Appliancemates HPA200 Replacement Filter captures 99.97% of particles ≥ 0.3 µm, fits Honeywell HPA200‑series units, and includes carbon pre‑filters, but it carries a $24.99 price tag and a heavier package.

This filter’s headline spec is its true HEPA H13 rating with a 99.97% capture rate for particles ≥ 0.3 microns, matching the performance benchmark set by premium OEM filters. It also ships with an activated carbon pre‑filter that tackles odors and VOCs, a feature not every aftermarket option includes.

In the broader roundup, the Appliancemates unit is noticeably heavier than the Honeywell HRF‑H1 (0.4 lb) and the Funmit HPA200 filter (1.52 lb), and it also exceeds the Isinlive filter’s 1.79 lb weight. Those competitors tend to be lighter, but the Appliancemates filter compensates with a larger coverage area of 310 sq ft and a full‑year HEPA replacement interval.

User feedback repeatedly praises the filter’s ability to curb dust, pollen, pet dander, smoke, and even VOC odors, echoing professional reviewers’ note that the carbon pre‑filters “effectively reduce household odors.” The downside that surfaces in reviews is the quarterly replacement schedule for the pre‑filters, which adds recurring maintenance tasks. Additionally, because the filter is an aftermarket, non‑OEM part, some users caution that fit and long‑term durability may not mirror the original Honeywell components.

Best for: Owners of Honeywell HPA200‑series air purifiers who want true HEPA‑level filtration, odor control via carbon pre‑filters, and coverage for rooms up to 310 sq ft.

Avoid if: You need the cheapest possible filter or prefer washable, reusable media that reduces long‑term replacement costs.

TL;DR: The Honeywell HRFSP1 costs $21.14, weighs just 0.53 lb, and promises pet‑odor removal up to 3.5× faster, making it a solid budget pick for compatible Honeywell purifiers.

This filter’s standout claim is an odor‑reduction rate of up to 3.5× faster than standard filters, thanks to its activated carbon and zeolite media. At 0.53 lb and with dimensions of 0.39 × 10.6 × 6.9 inches, it’s compact enough to slip into most Honeywell units without fuss.

Compared with other Honeywell options in the same roundup, the HRFSP1 is heavier than the HRF‑U1’s 0.29 lb weight and the HRF‑C1’s 0.41 lb weight, and its 6.9‑inch depth exceeds the HRF‑C1’s 4.5‑inch depth and the HRF‑U1’s 127 mm depth. However, it still fits a broader range of models, covering everything from the HPA3100 to the HPA5350 series.

Reviewers consistently highlight how the filter “makes all the difference” for cat and dog smells when paired with a Honeywell HEPA unit. Users note the fast odor‑cutting performance and appreciate the 4.7‑star rating from 347 reviewers, while also acknowledging the need for regular three‑month replacements.

Technically, the HRFSP1 is an S‑series Enhanced filter designed specifically for pet odors. It isn’t washable, so you’ll swap it out on schedule, and it slots between the HEPA filter and pre‑filter in compatible models.

Best for: Entry‑level buyers or those on a tight budget — the Honeywell HRFSP1 offers Depth: 175 mm (6.9 inches)

Avoid if: You need powerful performance or professional‑grade features

TL;DR: The Honeywell HRF‑C1 replacement filter delivers 95 % capture of 2‑micron particles, fits a 4.5‑inch deep slot, and costs $22.04, making it a solid budget choice for compatible Honeywell, Vicks and Holmes units.

This filter’s headline spec is its 95 % filtration efficiency at a minimum particle size of 2 microns, which covers common allergens like dust, pollen, pet dander and smoke. It measures 9.7 × 1.5 × 4.5 inches and weighs just 0.41 lb, so it slides into the unit without adding bulk.

Compared with other filters in the roundup, the HRF‑C1 is lighter than the Honeywell HRFSP1 (≈0.53 lb) and considerably shallower—its 4.5‑inch depth is less than the HRFSP1’s 6.9‑inch depth. The HRF‑H1 weighs about the same at 0.4 lb but captures particles down to 0.3 microns, whereas the HRF‑C1 stops at 2 microns, highlighting the true‑HEPA advantage of the HRF‑H1. The HRF‑U1 is even lighter at 0.29 lb, but it also offers a true‑HEPA‑compatible design.

Users consistently praise the filter’s odor‑reducing activated‑carbon layer, noting fewer cooking smells and pet odors after a single replacement. Professional reviewers point out the “HEPA‑type” classification, meaning it falls short of true HEPA standards for sub‑2‑micron particles. The filter runs for six months before needing a swap, which aligns with the manufacturer’s recommended replacement interval.

Technical details include an air‑change rate of 4.8 ACH, a dual‑action HEPA‑type pre‑filter with odor reduction, and compatibility with a long list of Honeywell, Vicks and Holmes models. The filter is packaged singly and backed by a one‑year warranty.

Best for: Budget-conscious buyers seeking a reliable entry-level option — the Honeywell HRF-C1 offers Depth: 4.5 inches (114 mm)

Avoid if: You need advanced features or professional‑grade performance, especially true HEPA filtration for sub‑2‑micron particles.

TL;DR: The Honeywell HRFSS1 filter delivers True HEPA‑level 99.97% particle capture down to 0.3 µm, adds an odor‑reducing carbon layer, and fits a compact 9.91 mm width, but its $32.79 price and three‑month replacement schedule make it a premium‑cost choice.

What really sets the HRFSS1 apart is its dual‑stage filtration: a True HEPA core that traps 99.97 percent of particles as small as 0.3 microns, paired with a treated activated carbon pre‑filter that tackles odors, smoke, and volatile compounds. The filter measures 269.24 mm in height, 175.26 mm in length, and only 9.91 mm in width, giving it a sleek profile that slides easily into the Honeywell HPA series units.

Compared with the other ten filters in this roundup, the HRFSS1 is notably taller than the Appliancemates HPA300 (40.64 mm high) and the Isinlive HEPA replacement (40.64 mm high), yet its width of just 9.91 mm is dramatically slimmer than the 165.1 mm widths common to most peers. Its length of 175.26 mm sits between the 259.08 mm length of the Appliancemates HPA300 and the very short 41 mm length of the Funmit HPA300 filter. The Honeywell HRF‑H1, another Honeywell offering, is half the height (123 mm) and twice as wide (42 mm), making the HRFSS1 the most elongated yet thinnest option in the group.

User reviews consistently praise the filter’s ability to clear smoke and pet odors quickly, noting the “quiet operation” and “effective air clearing” that professional reviewers also highlighted. On the flip side, owners mention the need to replace the pre‑filter four times a year, which aligns with the manufacturer‑stated three‑month replacement interval. Because the filter is designed for rooms up to a medium size, it may fall short in large, open‑concept spaces.

Best for: Those prioritizing quality and willing to pay for premium performance — the Honeywell HRFSS1 offers Height: 269.24 mm.

Avoid if: You're shopping on a tight budget — it's priced at $32.79.

TL;DR: At $16.78, the Sgizoku Honeywell Filter delivers True HEPA 99.97% particle capture at 0.3 µm, fits Honeywell H‑series units, and covers rooms up to 200 sq ft, all in a lightweight 0.7‑lb package.

The filter’s headline spec is its 99.97% efficiency at trapping particles as small as 0.3 microns, meeting True HEPA standards while also housing an activated‑carbon pre‑filter. Its compact dimensions—4.0 inches high, 5.0 inches wide, and 3.0 inches deep—let it slide into the Honeywell HPA‑050, HPA‑150 and other listed models without fuss.

Compared with the other ten contenders, the Sgizoku unit is heavier than the ultra‑light HRF‑U1 (0.29 lb) and the HRF‑SP1 (≈0.53 lb), but still lighter than many bulkier options. It’s shallower than the HRF‑U1’s 127 mm depth, while its 5.0‑inch width exceeds that model’s 25.4 mm, giving it a sturdier footprint. All peers share a two‑stage design, but the Sgizoku’s inclusion of both HEPA and carbon layers matches the filtration approach of the HRF‑U1 and HRF‑C1.

Customers praise the filter for noticeably reducing dust, pollen and pet dander, and they appreciate the tool‑free installation. Professional reviewers note the high capture rate but caution that performance claims rely on OEM specs rather than independent lab data. The annual replacement schedule—12 months, or 2‑3 months in high‑dust homes—means you’ll need to budget for recurring purchases.

Technically, the filter offers two stages (HEPA plus carbon), targets a broad range of contaminants, and is rated for up to 200 sq ft per compatible Honeywell purifier. It’s not washable, and the package supplies two HEPA filters plus eight carbon pre‑filters, giving you a ready supply for the first year.

Best for: Entry‑level buyers or those on a tight budget — the Sgizoku Honeywell Filter offers Depth: 3.0 inches (76 mm)
