In general, HEPA filter cartridges don’t come in a universally standardized size. The size mainly depends on the design of the device, airflow, filtration area, and the specific application. Even among H13 HEPAフィルター, various sizes can be found in totally different products.
The next part will classify them by industry:
Small HEPA Filters
Mini HEPA filters are designed for small consumer electronics and localized appliances, offering very effective air filtration. These small filters are typically made with a strong, lightweight plastic frame and can handle low airflow rates from 10 to 80 CFM. As they are designed for use in places where replacements happen frequently, such as smart home robots and portable devices, it is very important to keep their size consistent in order to prevent air bypass.
| mm | inches | Typical Application |
|---|---|---|
| 40 × 40 × 15 | 1.6 × 1.6 × 0.6 | Mini Air Purifiers |
| 60 × 60 × 20 | 2.4 × 2.4 × 0.8 | Small Air Purifiers |
| 70 × 100 × 25 | 2.8 × 3.9 × 1.0 | Robot Vacuums |
| 90 × 90 × 25 | 3.5 × 3.5 × 1.0 | ハンディクリーナー |
| 120 × 120 × 25 | 4.7 × 4.7 × 1.0 | Car Air Purifiers |
Medium HEPA Filters
Mini HEPA filters are designed for small consumer electronics and localized appliances, offering very effective air filtration. These small filters are typically made with a strong, lightweight plastic frame and can handle low airflow rates from 10 to 80 CFM. As they are designed for use in places where replacements happen frequently, such as smart home robots and portable devices, it is very important to keep their size consistent in order to prevent air bypass.
| mm | Typical Application |
|---|---|
| 180 × 180 × 30 | Residential Air Purifier |
| 200 × 250 × 30 | 空気清浄機 |
| 250 × 250 × 35 | Fresh Air Ventilation System |
| 300 × 300 × 46 | Commercial Air Cleaner |
| 305 × 305 × 69 | HVAC System |
Large HEPA Panel Filters
In critical environments where contamination must be completely avoided, heavy-duty large HEPA panel filters are designed to manage high airflow rates ranging from 500 to over 2000 cubic meters per hour. These high-capacity rigid filters feature top-quality aluminum or galvanized steel frames and are typically requested with high efficiency ratings of H13 and H14.
Each panel is reinforced to maintain its shape and prevent any wrinkling or deformation when subjected to high pressure, making it a standard choice in semiconductor cleanrooms, pharmaceutical labs, biosafety labs, and advanced hospital HVAC systems.
| mm | inches |
|---|---|
| 305 × 305 × 150 | 12 × 12 × 6 |
| 484 × 484 × 220 | 19 × 19 |
| 610 × 610 × 69 | 24 × 24 × 3 |
| 610 × 610 × 90 | 24 × 24 × 4 |
| 610 × 1220 × 69 | 24 × 48 × 3 |
Cylindrical HEPA Filters
When your equipment design calls for 360° omnidirectional air intake or localized high vacuum suction, cylindrical HEPA filters provide superior geometric benefits. These filters enclose the filter media in a strong circular cartridge that provides a larger effective filtration area than flat-panel filters of the same size.
| Outside Diameter | 高さ | Typical Application |
|---|---|---|
| Ø50 × 80 mm | 80 mm | Small Equipment |
| Ø80 × 120 mm | 120 mm | 掃除機 |
| Ø120 × 200 mm | 200 mm | Industrial Dust Collectors |
| Ø150 × 300 mm | 300 mm | Industrial Air Filtration |
Pleat Depth
Commercial air filtration is more than just physical length and width. The depth of the pleat in your HEPA filter is proportional to the aerodynamic performance of your system. A more sophisticated pleat design increases the filter’s surface area exponentially; this design choice significantly reduces the initial pressure drop, reduces strain on the system and maximizes the overall service life before replacement.
Many applications require very specialized dimension profiles. For instance, a common robotic vacuum uses the slim 25mm profile, whereas a semiconductor cleanroom or pharmaceutical facility will require the deep-pleat panel sizes from 69mm up to 220mm to ensure absolute containment control.
Common Thicknesses
| 10 mm | 46 mm |
| 15 mm | 69 mm |
| 20 mm | 90 mm |
| 25 mm | 150 mm |
| 30 mm | 220 mm |
The Greater the Thicknes
- The larger the filtration area
- Lower wind resistance
- Longer service life
- The higher the cost

Common OEM & ODM Custom HEPA Filter Sizes
For HEPA filter manufacturers such as HIFINE, most products are custom-designed rather than produced in fixed standard dimensions. Manufacturers typically develop filters according to customer drawings, samples, or equipment specifications.
Typical Customization Range
- 長さ： 40–1220 mm
- Width: 40–610 mm
- Thickness: 10–220 mm
- Filter Efficiency: H10, H11, H12, H13, H14
- Frame Materials: ABS, PP, Aluminum, Galvanized Steel, Stainless Steel
- Seal Materials: PU, EVA, EPDM, Silicone
- Filter Shapes: Flat Panel, V-Bank, Cylindrical, Conical, Custom-Shaped
Most OEM projects begin with a drawing, CAD file, sample, or equipment model number. The manufacturer then designs the filter dimensions and structure based on installation space, airflow requirements, filtration efficiency, and pressure drop, rather than relying on standard off-the-shelf sizes.
概要
The following table summarizes the relationship between HEPA filter sizes and their typical applications.
| Size Range | Typical Applications | Airflow Characteristics |
|---|---|---|
| 40–120 mm | Car Air Purifiers, Robot Vacuums, Handheld Vacuums | Low airflow, compact design |
| 180–300 mm | Residential Air Purifiers, Fresh Air Systems | Medium airflow, most common consumer sizes |
| 305–610 mm | HVAC Systems, Commercial Air Cleaners | High airflow, extended service life |
| 610 × 610 mm and larger | Cleanrooms, Hospitals, Laboratories, Semiconductor Manufacturing | High airflow, high-efficiency filtration |
For B2B buyers, size is only one factor when selecting a HEPA filter. A complete evaluation should also consider the filtration efficiency (H11–H14), rated airflow, initial 圧力損失, dust-holding capacity, frame material, gasket design, and sealing method to ensure the filter meets the performance requirements of the intended application.
