Replacement HEPA H14 filter with activated carbon for the HEPA FILTER BOX L. Captures fine dust, pollen, aerosols and allergens, while the activated carbon layer helps reduce odors, smoke and volatile organic compounds. Ideal as a post-filtration stage downstream of heat recovery ventilation units.
HEPA H14 replacement filter with activated carbon for the HEPA FILTER BOX L.
HEPA H14 CARBON FILTER L is a replacement filter element designed for use in the HEPA FILTER BOX L duct filter box. It combines highly efficient HEPA H14 filtration with an activated carbon layer that helps reduce odors and selected gaseous pollutants.
The filter is ideal for post-filtration of supply air downstream of a heat recovery ventilation unit. While most HRV units are equipped with G4, M5 or F7 filters, a HEPA H14 filter captures significantly finer particles and further improves indoor air quality.
It is particularly suitable for households with allergy sufferers, children's rooms, bedrooms, offices and buildings located in areas with increased dust levels, pollen exposure or heavy traffic.
The filter combines two important air purification technologies:
| HEPA H14 | captures fine dust, pollen, allergens, aerosols and other microscopic particles |
| Activated Carbon | helps reduce odors, smoke and selected volatile organic compounds (VOC) |
The result is a high level of air filtration and improved indoor comfort.
| HEPA H14 Filtration | high-efficiency capture of fine airborne particles |
| Activated Carbon Layer | helps reduce odors, smoke and VOC compounds |
| Ideal After HRV Units | additional filtration stage for supply air |
| Easy Replacement | quick and simple replacement in the HEPA FILTER BOX L |
| Long Service Life | typically 8–12 months depending on operating conditions |
The HEPA H14 CARBON FILTER L was tested in our laboratory using the HEPA FILTER BOX L. The measured values help with proper fan selection and assessing suitability for specific installations.
Selected measured values:
| Airflow | Pressure Loss |
| 119 m³/h | 26 Pa |
| 141 m³/h | 38 Pa |
| 174 m³/h | 55 Pa |
| 217 m³/h | 70 Pa |
| 261 m³/h | 88 Pa |
| 308 m³/h | 105 Pa |
| 357 m³/h | 130 Pa |
| 371 m³/h | 150 Pa |
HEPA Filter Pressure Loss Graph:
| Fine Dust | PM2.5, PM1 and other microscopic particles |
| Pollen and Allergens | helps reduce pollen levels indoors |
| Aerosols | fine airborne particles |
| Smoke and Odors | reduced by the activated carbon layer |
| VOC Compounds | helps reduce selected volatile organic compounds |
| Filter Type | HEPA H14 + Activated Carbon |
| Dimensions | 337 × 360 × 42 mm |
| Weight | 0.63 kg |
| Recommended Service Life | 8–12 months |
| Application | HEPA FILTER BOX L |
HEPA H14 CARBON FILTER L is a consumable filter element that should be replaced regularly. Only a clean filter can ensure proper airflow, low pressure loss and maximum filtration efficiency.
Regular filter replacement helps maintain high indoor air quality and ensures the proper operation of the HEPA FILTER BOX L.
