What This Product Is
This filter set is a compatible replacement solution for Wolf CWL 300B and Wolf CWL 400B heat recovery ventilation units with flap recuperators. The set includes two filters designed to filter both incoming supply air and outgoing extract air. The standard configuration is G4+G4, providing economical filtration suitable for most residential applications. These filters replace the original Wolf filters with a cost-effective alternative that maintains proper system performance.
Filter Class Comparison
Understanding filter classes helps you choose the right option for your ventilation needs:
- G4 filters capture medium-sized particles down to 10 μm, including dust, pollen, and larger airborne particles. They provide adequate protection for general residential use and both supply and extract air applications.
- F7 filters capture ultra-fine particles down to 0.3 μm, including fine dust, bacteria, and combustion particles. F7 is recommended for supply air when enhanced indoor air quality is required, such as in urban areas or for allergy sufferers.
For most standard residential installations, the G4+G4 configuration offers reliable performance. If you need enhanced filtration, consider upgrading the supply air filter to F7.
